    In general practice, disc hernia is increasingly being questioned about its relation with traffic injuries. In this study, we examined the image findings of cervical disc herniation for findings indicative of traumatic hernia. In 2008, we examined 35 cases of cervical disc herniation at our hospital by MRI. The patients were divided into two groups; patients with trauma history (19 cases) and those without (16 cases), and their images were compared. Disc herniation in the trauma group showed high intensity at T2, with some of the patients in this group also indicating continuous high intensity of the internal and herniated discs. Traumatic force was found to cause swelling under the laryngeal soft tissue. Cases with further flexion injury showed interspinous ligament hemorrhage. These findings strongly suggest the involvement of injury. But given that some younger patients in the non-trauma group also show high intensity at T2*, attention must be paid not to confuse swelling below the larynx with inflammation of the longus colli muscle.

    Full Text Available The spontaneous regression of herniated cervical discs is not a well-established phenomenon. However, we encountered a case of a spontaneous regression of a severe radiculopathic herniated cervical disc that was treated with acupuncture, pharmacopuncture, and herb medicine. The symptoms were improved within 12 months of treatment. Magnetic resonance imaging (MRI conducted at that time revealed marked regression of the herniated disc. This case provides an additional example of spontaneous regression of a herniated cervical disc documented by MRI following non-surgical treatment.

    Therapeutic armamentarium for symptomatic intervertebral disc herniation includes conservative therapy, epidural infiltrations (interlaminar or trans-foraminal), percutaneous therapeutic techniques and surgical options. Percutaneous, therapeutic techniques are imaging-guided, minimally invasive treatments for intervertebral disc herniation which can be performed as outpatient procedures. They can be classified in 4 main categories: mechanical, thermal, chemical decompression and biomaterials implantation. Strict sterility measures are a prerequisite and should include extensive local sterility and antibiotic prophylaxis. Indications include the presence of a symptomatic, small to medium sized contained intervertebral disc herniation non-responding to a 4–6 weeks course of conservative therapy. Contraindications include sequestration, infection, segmental instability (spondylolisthesis), uncorrected coagulopathy or a patient unwilling to provide informed consent. Decompression techniques are feasible and reproducible, efficient (75–94% success rate) and safe (>0.5% mean complications rate) therapies for the treatment of symptomatic intervertebral disc herniation. Percutaneous, imaging guided, intervertebral disc therapeutic techniques can be proposed either as an initial treatment or as an attractive alternative prior to surgery for the therapy of symptomatic herniation in both cervical and lumbar spine. This article will describe the mechanism of action for different therapeutic techniques applied to intervertebral discs of cervical and lumbar spine, summarize the data concerning safety and effectiveness of these treatments, and provide a rational approach for the therapy of symptomatic intervertebral disc herniation in cervical and lumbar spine.

    Full Text Available Brown-Sequard syndrome is commonly seen in the setting of spinal trauma or an extramedullary spinal neoplasm. The clinical picture reflects hemisection of the spinal cord. We report a rare case of Brown-Sequard syndrome caused by a large cervical herniated disc. A 63-year-old man presented with progressive right hemiparesis and disruption of pain and temperature sensation on the left side of the body. Magnetic resonance imaging showed large C3-C4 disc herniation compressing the spinal cord at that level, with severe canal stenosis from C4 through C7. Decompressive cervical laminoplasty was performed. After surgery, complete sensory function was restored and a marked improvement in motor power was obtained.

    To explore clinical presentations and the operational opportunity of traumatic cervical disc herniation. From June 2002 to June 2009,40 patients with traumatic cervical disc herniation were treated. There were 24 males and 16 females, with an average age of 43.2 years old ranging from 30 to 56 years. There were 36 patients with single intervertebral disc herniation and 4 patients with double. The injury level of those patients were at C3,4 in 16 cases, C4,5 in 10 cases, C5,6 in 12 cases and C6,7 in 6 cases. Among them, 18 patients showed spinal cord signal changes by MRI, 5 patients suffered from nothing but neck and shoulder pain, 8 patients with nerve root stimulation; 10 patients with spinal cord compression, and 17 patients had both nerve root stimulation and spinal cord compression symptoms. Conservative treatment were applied to 13 patients with neck and shoulder pain and nerve root stimulation, 5 cases of which were transferred to operation in case of poor effects, and Odom criteria were used to assess operational effects. Twenty-seven patients with spinal cord compression accepted operation from 1 to 27days after their trauma, 16 of which were operated in 5 days (early operational group with an JOA score of 11.3 +/- 2.8), other 11 cases were operated from 5 to 27 days (delayed operational group with an JOA score of 11.4 +/- 2.9 ), then functional assessment of spinal cord were assessed according to JOA criteria. Three patients who were transferred from conservative treatment recovered excellently according to Odom criteria and the other 2 were good at final followed-up. JOA score of early operational group increased from (11.3 +/- 2.8) to (15.3 +/- 1.8) one week after operation (P traumatic cervical disc herniation and cervical spondylosis. Early operation is favorable to the recovery of neurological function in patients with spinal cord compression.

    Computed tomography (CT) is an accurate method of diagnosing cervical disc herniation in patients with radiculopathy. We evaluated 7 patients for the treatment of radiculopathy. The CT features of lateral cervical disc herniation include: (1) plain CT reveals a soft tissue mass compatible with laterally herniated disc material within the intervertebral foramen; (2) plain CT shows a soft tissue mass, which implies a fragmented disc, in the lateral recess; (3) CT with the intravenous administration of the contrast medium shows no delineation of the nerve root in the intervertebral foramen; and (4) CT metrizamide myelography demonstrates the filling defect of the root sleeve and hypertrophy of the nerve root. In those seven patients, all CT examinations were interpreted as positive for lateral disc herniation. There was a good correlation between the results of the neurologic examination and the CT findings. We wish to stress the usefulness of CT in the diagnosis of lateral cervical disc herniation.

    A discogenic cervical headache is a subtype of cervicogenic headache (CEH) that arises from a degenerative cervical disc abnormality. The purpose of this study was to evaluate the clinical outcome of percutaneous endoscopic cervical discectomy (PECD) for patients with chronic cervical headache due to soft cervical disc herniation. Seventeen patients underwent PECD for intractable headache. The inclusion criteria were soft disc herniation without segmental instability, proven by both local anesthesia and provocative discography for headache unresponsive to conservative treatment. The mean follow-up period was 37.6 months. Fifteen of the 17 patients (88.2%) showed successful outcomes based on the Macnab criteria. Pain scores on a visual analog scale (VAS) improved from a preoperative mean of 8.35±0.79 to 2.12±1.17, postoperatively (P<0.01). The mean disc height decreased from 6.81±1.08 to 5.98±1.07 mm (P<0.01). There was no newly developed segmental instability or spontaneous fusion on follow-up radiography. In conclusion, PECD appears to be effective for chronic severe discogenic cervical headache under strict inclusion criteria. (orig.)

    This study evaluated the contribution of computed tomographic discography (CTD) to the surgical indications and selection of surgical techniques in cervical disc herniation. The study population consisted of 73 patients who were diagnosed as having cervical disc herniation by CTD: Of them, hernia mass was confirmed by surgery in 64 patients (a concordance rate of 88% between CTD and surgical findings). In evaluable 40 patients receiving computed tomographic myelography (CTM), the rate of flattened spinal cord on CTM was significantly correlatd with postoperative prognosis. Flattened spinal cord was favorably improved. Higher preoperative flat rate was associated with severer cervical disc herniation. CTD provided the information concerning the positional relation in the posterior longitudinal ligament of hernia mass. Preoperative severity, preoperative rate of flattened spinal cord, and the site of protrusion of hernia mass were independent of surgical outcome. (N.K.).

    Objective: To evaluate the security and therapeutic effect for the treatment of cervical disc herniation with O 2 -O 3 mixture. Methods: Thirty-two patients with cervical herniated discs verified by MRI were selected in study, and all patients presented the symptoms of upper limb, cervical and shoulder areas pain. The procedure was guided by DSA and their puncture route was defined as the right common cervical artery and trachea clearance. 1.5-3.0 ml O 2 -O 3 mixture gas at (30-50) μg/ml was injected into every herniated disc space and 3-5 ml mixture gas was injected in paraspinal space. Results: Thirty-two patients were followed up from 3 to 32 months after treatment. The therapeutic effect showed that 17 cases (53.1%) had excellent recovery, 8 cases (25.0%) had significant relief of symptoms, and 7 cases (21.9%) got failure in treatment. No serious complication occurred. Conclusion: The therapeutic method developed by using O 2 -O 3 mixture injection in cervical intradiscal space was a safe and effective method for the treatment of the cervical disc herniation.

    2012-01-01

    A 34-year-old woman was seen in a physiotherapy department with signs and symptoms of cervical radiculopathy. Loss of cervical lordosis and a large paracentral to intraforaminal disc prolapse (8 mm) at C5-C6 level was reported on MRI. She was taking diclofenac sodium, tramadol HCl, diazepam and pregabalin for the preceding 2 months and no significant improvement, except temporary relief, was reported. She was referred to physiotherapy while awaiting a surgical opinion from a neurosurgeon. In physiotherapy she was treated with mobilisation of the upper thoracic spine from C7 to T6 level. A cervical extension exercise was performed with prior voluntary extension of the thoracic spine and elevated shoulders. She was advised to continue the same at home. General posture advice was given. Signs and symptoms resolved within the following four sessions of treatment over 3 weeks. Surgical intervention was subsequently deemed unnecessary.

    The purposes of this study are to delineate the clinical course and MRI findings of patients with disc hernias which regressed spontaneously and to determine who is eligible for conservative treatment. Twenty-three patients with mild cervical myelopathy (initial Japanese Orthopedic Association (JOA) scores >10) caused by soft disc herniation were treated conservatively for more than two years (13 males, 10 females, mean age 50, mean follow-up 3.6 years). The investigated items included JOA scores and MRI findings (morphology of disc herniation). Morphology of disc herniation was classified into focal type (herniated mass persisting at the intervertebral level) and diffuse type (herniated mass migrating rostrally or caudally) in the sagittal plane and median type or paramedian type in the axial plane. The mean JOA scores were 13.4±1.5 before treatment, and 16.0±1.0 at follow-up. Regression of herniation was observed in 14 patients (Group A), while no regression was seen in 9 patients (Group B). The JOA scores were 13.7±1.5 (Group A) and 14.0±1.6 (Group B) before treatment, and 16.3±1.6 and 15.7±1.2 at follow-up, respectively. On sagittal MR images, diffuse-type herniation was observed in 9 patients (64%) and focal-type in 5 (36%) in Group A, and 3 (33%) and 6 (67%) in Group B, respectively. On axial images, median-type herniation was observed in 10 patients (71%), and paramedian-type in 4 (29%) in Group A, and 6 (67%) and 3 (33%) in Group B, respectively. Spontaneous soft disc regression in patients with cervical myelopathy was observed in more than half of those treated conservatively for longer than 2 years. Conservative treatment can be recommended for patients with mild cervical myelopathy, especially when caused by median-and/or diffuse-type disc hernia, although close observation is mandatory.

  16. Spontaneous Cervical Intradural Disc Herniation Associated with Ossification of Posterior Longitudinal Ligament

    Dachuan Wang

    2014-01-01

    Full Text Available Intradural herniation of a cervical disc is rare; less than 35 cases have been reported to date. A 52-year-old man with preexisting ossification of posterior longitudinal ligament developed severe neck pain with Lt hemiparesis while asleep. Neurological exam was consistent with Brown-Séquard syndrome. Magnetic resonance images showed a C5-6 herniated disc that was adjacent to the ossified ligament and indenting the cord. The mass was surrounded by cerebrospinal fluid signal intensity margin, and caudally the ventral dura line appears divided into two, consistent with the “Y-sign” described by Sasaji et al. Cord edema were noted. Because of preexisting canal stenosis and spinal cord at risk, a laminoplasty was performed, followed by an anterior C6 corpectomy. Spot-weld type adhesions of the posterior longitudinal ligament to the dura was noted, along with a longitudinal tear in the dura. An intradural extra-arachnoid fragment of herniated disc was removed. Clinical exam at 6 months after surgery revealed normal muscle strength but persistent mild paresthesias. It is difficult to make a definite diagnosis of intradural herniation preoperatively; however, the clinical findings and radiographic signs mentioned above are suggestive and should alert the surgeon to look for an intradural fragment.

    This study aims at evaluating and comparing the effects of cervical stability training to combined cervical and core stability training in patients with neck pain and cervical disc herniation. Fifty patients with neck pain and cervical disc herniation were included in the study, randomly divided into two groups as cervical stability and cervical-core stability. Training was applied three times a week in three phases, and lasted for a total duration of 8 weeks. Pain, activation and static endurance of deep cervical flexor muscles, static endurance of neck muscles, cross-sectional diameter of M. Longus Colli, static endurance of trunk muscles, disability and kinesiophobia were assessed. Pain, activation and static endurance of deep cervical flexors, static endurance of neck muscles, cross-sectional diameter of M. Longus Colli, static endurance of trunk muscles, disability and kinesiophobia improved in both groups following the training sessions (p training methods revealed that the cervical stability group produced a greater increase in the right transverse diameter of M. Longus Colli (p training provided benefit to patients with cervical disc herniation. The addition of core stability training did not provide any additional significant benefit. Further research is required to investigate the efficacy of combining other techniques with cervical stability training in patients with cervical disc herniation. Both cervical stability training and its combination with core stability training were significantly and similarly effective on neck pain and neck muscle endurance in patients with cervical disc herniation. © 2017 European Pain Federation - EFIC®.

  18. Prevalence of annular tears and disc herniations on MR images of the cervical spine in symptom free volunteers

    Ernst, C.W.; Stadnik, T.W.; Peeters, E.; Breucq, C.; Osteaux, M.J.C.

    2005-01-01

    Study design: Prospective MR analysis of the cervical spine of 30 asymptomatic volunteers. Objectives: To evaluate the prevalence of annular tears, bulging discs, disc herniations and medullary compression on T2-weighted and gadolinium-enhanced T1-weighted magnetic resonance (MR) images of the cervical spine in symptom free volunteers. Summary of background data: Few studies have reported the prevalence of cervical disc herniations in asymptomatic people, none have reported the prevalence of cervical annular tears on MR images of symptom free volunteers. Materials and methods: Thirty symptom-free volunteers (no history or symptoms related to the cervical spine) were examined using sagittal T2-weighted fast spin-echo (SE), sagittal gadolinium-enhanced T1-weighted SE imaging and axial T2 * -weighted gradient echo (GRE). The prevalence of bulging discs, focal protrusions, extrusions, nonenhancing or enhancing annular tears and medullary compression were assessed. Results: The prevalence of bulging disk and focal disk protrusions was 73% (22 volunteers) and 50% (15 volunteers), respectively. There was one extrusion (3%). Eleven volunteers had annular tears at one or more levels (37%) and 94% of the annular tears enhanced after contrast injection. Asymptomatic medullary compression was found in four patients (13%). Conclusion: Annular tears and focal disk protrusions are frequently found on MR imaging of the cervical spine, with or without contrast enhancement, in asymptomatic population. The extruded disk herniation and medullary compression are unusual findings in a symptom-free population

  19. The impact of generalized joint laxity (GJL) on the posterior neck pain, cervical disc herniation, and cervical disc degeneration in the cervical spine.

    Generalized joint laxity (GJL) can have a negative impact on lumbar spine pathology, including low back pain, disc degeneration, and disc herniation, but the relationship between GJL and cervical spine conditions remains unknown. To investigate the relationship between GJL and cervical spine conditions, including the prevalence of posterior neck pain (PNP), cervical disc herniation (CDH), and cervical disc degeneration (CDD), in a young, active population. Retrospective 1:2 matched cohort (case-control) study from prospectively collected data PATIENT SAMPLE: Of a total of 1853 individuals reviewed, 73 individuals with GJL (study group, gruop A) and 146 without GJL (control group, Group B) were included in the study according to a 1:2 case-control matched design for age, sex, and body mass index. The primary outcome measure was the prevalence and intensity of PNP at enrollment based on a visual analogue scale score for pain. The secondary outcome measures were (1) clinical outcomes as measured with the neck disability index (NDI) and 12-item short form health survey (SF-12) at enrollment, and (2) radiological outcomes of CDH and CDD at enrollment. We compared baseline data between groups. Descriptive statistical analyses were performed to compare the 2 groups in terms of the outcome measures. The prevalence and intensity of PNP were significantly greater in group A (patients with GJL) than in group B (patients without GJL) (prevalence: p=.02; intensity: p=.001). Clinical outcomes as measured with NDI and SF-12 did not differ significantly between groups. For radiologic outcomes, the prevalence of CDD was significantly greater in group A than in group B (p=.04), whereas the prevalence of CDH did not differ significantly between groups (p=.91). The current study revealed that GJL was closely related to the prevalence and intensity of PNP, suggesting that GJL may be a causative factor for PNP. In addition, GJL may contribute to the occurrence of CDD, but not CDH. Spine

    Objective: To explore the value of MR imaging-guided percutaneous cervical discectomy and discolysis with oxygen-ozone mixture for treatment of cervical disc herniation. Methods: Eight herniated cervical discs in 7 patients were diagnosed by MRI, inclluding 5 discs of lateral protruding type, 2 discs of paramedian protruding type and one disc of central protruding type. All patients underwent MR imaging-guided percutaneous cervical discectomy and discolysis with oxygen-ozone mixture. The procedures were guided by a set of 0.23 T open MR system mounted with iPath 200 optical tracking system. The herniated portion of the disc was punctured with a 14 G MR-comparible needle in the healthy side via anterolateral oblique route. The interventional steps were as follows: firstly, cut herniated part with percutaneous discectomy probe and inject 2ml oxygen-ozone mixture of 60 μg/ml; secondly, retreat the needle to the disc center, resect nucleus pulposus, and inject 2 ml oxygen-ozone mixture of 60 μg/ml; secondly, retreat the needle to the disc center, resect nucleus pulposus, and inject 2 ml oxygen-ozone mixture of 60 μg/ml. All patients were followed up for 6 months, with 4 patients by telephone and 3 patients in outpatient clinic. The effect of treatment was evaluated according to Williams postoperative assessment standard. Results: All procedures were performed successfully. The clinical outcome was evaluated as excellent in 5 cases, good in 1 cases and fair in 1 case. The total ratio of excellent and good was 85.7%. No serious complication occurred expect 1 case with intraoperative paroxysmal pain. Conclusion: MR imaging-guided percutaneous cervical discectomy and discolysis with oxygen-ozone mixture was a safe, effective and minimally invasive method for the treatment of cervical disc herniation.

  1. A calcified cervical intervertebral disc in a child and a thoracic disc calcification in an adult with posterior herniation-radiographic, computed tomography and magnetic resonance imaging findings

    Jevtic, V.

    2004-01-01

    Background. Nucleus pulposus calcification in children is a relatively rare but well known clinical syndrome, usually localized at the level of the cervical spine. The exact aetiology still remains uncertain. Calcifications of the intervertebral discs in adults differ from the childhood variety. They are mainly degenerative in nature and occur at the level of midthoracic and upper lumbar spine. Potentially serious complications, posterior herniation of calcified disc may occur in both entities. Case reports. We report two cases of the calcification of the nucleus pulposus in a seven-year-old boy at the level of C7-T1 and a case of calcified intervertebral disc T11-T12 in a forty-five-year-old woman, with massive posterior herniation. Remission of symptoms was achieved with a conservative therapy alone. Clinical, radiographic, computed tomographic and magnetic resonance imaging (MRI) findings were analyzed in an attempt to investigate similarities and differences between both disease entities. Conclusion. Massive posterior herniation of calcified nucleus pulposus in a child was treated conservatively with a favourable outcome. A disappearance of symptoms followed quick resolution of herniated calcified masses. In adult variety extruded thoracic disc calcification was of a permanent type with no tendency towards spontaneous resolution and remission of symptoms after the conservative therapy. MRI seems to be able to depict disc calcification before a conventional radiography. The widening of affected discs in a paediatric patient was also better demonstrated by MRI. It would seem to support the theory of an increased intradiscal pressure as the precursor of annulus fibrosus ruptures and consecutive calcified disc herniations. (author)

  2. Cervical myelopathy due to single level disc herniation presenting as intramedullary mass lesion: What to do first?

    Murat Sakir Eksi

    2015-01-01

    Full Text Available Cervical myelopathy (CM is mostly a degenerative process ending in myelopathic and/or radiculopathic syndromes. On T2-weighted magnetic resonance imaging (MRI, CM appears as a hyperintense area near the spondylotic spine. This high intensity signal depends on the impact of outer forces and their duration. It also determines the prognosis of the surgical candidate. A 40-year-old male patient admitted to our clinic with right upper extremity weakness and hypoesthesia that had started 2 months earlier. On neurological examination there was 2/5 motor weakness of right biceps brachii, and hypoesthesia over right C6 dermatome. Right upper extremity deep tendon reflexes were hypoactive, but lower ones were hyperactive. After clinical and radiological work-up, preliminary diagnosis was directed to a spinal intramedullary tumor. Total resection of the herniated cervical disc fragment and the mass lesion was managed. Pathology of the mass lesion was compatible with subacute infarct tissue and inflammatory response. Final diagnosis was CM under effect of cervical disc herniation. Contrast-enhanced spinal cord myelopathic lesions are very rare and resemble much more tumors and inflammatory processes. However, the principal treatment approach totally differs depending on pathology. When there are both a disc herniation and a high clinical suspicion; biopsy should be delayed. The most probable solution will be surgery for the disc disease with thorough preoperative scanning of vascular malformations; clinical and radiological close follow-up after surgery. Biopsy or surgical resection can be performed if patient deteriorates despite the primary surgery.

  3. Cervical Intradural Disc Herniation Causing Progressive Quadriparesis After Spinal Manipulation Therapy: A Case Report and Literature Review.

    Yang, Hwan-Seo; Oh, Young-Min; Eun, Jong-Pil

    2016-02-01

    Cervical intradural disc herniation (IDH) is an extremely rare condition, comprising only 0.27% of all disc herniations. Three percent of IDHs occur in the cervical, 5% in the thoracic, and over 92% in the lumbar spinal canal. There have been a total of 31 cervical IDHs reported in the literature. The pathogenesis and imaging characteristics of IDH are not fully understood. A preoperative diagnosis is key to facilitating prompt intradural exploration in patients with ambivalent findings, as well as in preventing reoperation. The purpose of reporting our case is to remind clinicians to consider the possibility of cervical IDH during spinal manipulation therapy in patient with chronic neck pain.The patient signed informed consent for publication of this case report and any accompanying image. The ethical approval of this study was waived by the ethics committee of Chonbuk National University Hospital, because this study was case report and the number of patients was manipulation for chronic neck pain over the course of a month. The day prior, he had noticed neck pain and tingling in the bilateral upper and lower extremities during the manipulation procedure. The following day, he presented with bilateral weakness of all 4 extremities, which rendered him unable to walk. Neurological examination demonstrated a positive Hoffmann sign and ankle clonus bilaterally, hypoesthesia below the C5 dermatome, 3/5 strength in the bilateral upper extremities, and 2/5 strength in the lower extremities. This motor weakness was progressive, and he further complained of voiding difficulty.Urgent magnetic resonance imaging (MRI) of the cervical spine revealed large, central disc herniations at C4-C5 and C5-C6 that caused severe spinal cord compression and surrounding edema. We performed C4-C5-C6 anterior cervical discectomy and fusion.The patient's limb weakness improved rapidly within 1 day postoperatively, and he was discharged 4 weeks later. At his 12-month follow-up, the patient had

    To assess inter-modality variability when evaluating cervical intervertebral disc herniation using 64-slice multidetector-row computed tomography (MDCT) and magnetic resonance imaging (MRI). Three musculoskeletal radiologists independently reviewed cervical spine 1.5-T MRI and 64-slice MDCT data on C2-3 though C6-7 of 51 patients in the context of intervertebral disc herniation. Interobserver and inter-modality agreements were expressed as unweighted kappa values. Weighted kappa statistics were used to assess the extents of agreement in terms of the number of involved segments (NIS) in disc herniation and epicenter measurements collected using MDCT and MRI. The interobserver agreement rates upon evaluation of disc morphology by the three radiologists were in fair to moderate agreement (k = 0.39-0.53 for MDCT images; k = 0.45-0.56 for MRIs). When the disc morphology was categorized into two and four grades, the inter-modality agreement rates were moderate (k-value, 0.59) and substantial (k-value, 0.66), respectively. The inter-modality agreements for evaluations of the NIS (k-value, 0.78) and the epicenter (k-value, 0.79) were substantial. Also, the interobserver agreements for the NIS (CT; k-value, 0.85 and MRI; k-value, 0.88) and epicenter (CT; k-value, 0.74 and MRI; k-value, 0.70) evaluations by two readers were substantial. MDCT tended to underestimate the extent of herniated disc lesions compared with MRI. Multidetector-row computed tomography and MRI showed a moderate-to-substantial degree of inter-modality agreement for the assessment of herniated cervical discs. MDCT images have a tendency to underestimate the anterior/posterior extent of the herniated disc compared with MRI.

    Educating patients about receiving surgical procedures is becoming an important issue, as it can reduce anxiety and uncertainty while helping to hasten decisions for undergoing time sensitive surgeries. We evaluated a new integrated education model for patients undergoing cervical disc herniation surgery using a quasi-experimental design. The participants were grouped into either the new integrated educational model (n = 32) or the standard group (n = 32) on the basis of their ward numbers assigned at admission. Anxiety, uncertainty, and patient satisfaction were measured before (pre-test) and after the educational intervention (post-test-1) and post-surgery (post-test-2) to assess the effectiveness of the model in this intervention. We found that the generalized estimating equation modeling demonstrated this new integrated education model was more effective than the conventional model in reducing patients' anxiety and uncertainty (p approach to individual health. This novel systemic educational model enhances patient's understanding of the medical condition and surgery while promoting patient-caregiver interaction for optimal patient health outcomes. We present a comprehensive and consistent platform for educational purposes in patients undergoing surgery as well as reducing the psychological burden from anxiety and uncertainty. Integrating medicine, nursing, and new technologies into an e-practice and e-learning platform offers the potential of easier understanding and usage. It could revolutionize patient education in the future. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Background: Multiple sclerosis (MS is a chronic autoimmune, inflammatory demyelinating disease of the central nervous system. Commonly, MS patients present with accompanying degenerative vertebral disc diseases. Simultaneous disc herniations situated in the cervical or lumbosacral spine can mimic the clinical symptoms of MS and worsen patients’ quality of life.Objective: to investigate the incidence rate and clinical impact of accompanying disc herniations in patients with MS.Material and methods: Our study covered 330 patients (220 females and 110 males, mean age 40.5±12.4 years with clinically definite MS, according to McDonald’s criteria. Comprehensive neurological examinations, EDSS (Expanded Disability Status Scale assessments, and MRI neuroimaging were carried out. Statistical data processing was performed by using the method of variation analysis.Results: Relapsing-remitting MS (RRMS was diagnosed in 280 patients while 50 patients presented with secondary progressive MS (SPMS. Disc herniation was found in 64 (19.4% of our patients. Cervical disc pathology was detected in 38 patients (11.5% of the cases and lumbosacral - in 26 (7.9% of the cases. EDSS scores ranged from 2.5 to 5.5. EDSS evaluation showed statistically significantly worse scores in MS patients with disc herniation comorbidity (p<0, 05.Conclusion: Our own data confirm the assumption that MS patients often present with accompanying degenerative disc pathology. We suggest that comorbidity of disc herniation and MS exert an additional unfavorable effect on patient’s disability and individual quality of life.

    The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years). Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%). On control examinations, there was no finding of instability or cervical kyphosis. Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis.

  10. Percutaneous treatment of intervertebral disc herniation.

    Buy, Xavier; Gangi, Afshin

    2010-06-01

    Interventional radiology plays a major role in the management of symptomatic intervertebral disc herniations. In the absence of significant pain relief with conservative treatment including oral pain killers and anti-inflammatory drugs, selective image-guided periradicular infiltrations are generally indicated. The precise control of needle positioning allows optimal distribution of steroids along the painful nerve root. After 6 weeks of failure of conservative treatment including periradicular infiltration, treatment aiming to decompress or remove the herniation is considered. Conventional open surgery offers suboptimal results and is associated with significant morbidity. To achieve minimally invasive discal decompression, different percutaneous techniques have been developed. Their principle is to remove a small volume of nucleus, which results in an important reduction of intradiscal pressure and subsequently reduction of pressure inside the disc herniation. However, only contained disc herniations determined by computed tomography or magnetic resonance are indicated for these techniques. Thermal techniques such as radiofrequency or laser nucleotomy seem to be more effective than purely mechanical nucleotomy; indeed, they achieve discal decompression but also thermal destruction of intradiscal nociceptors, which may play a major role in the physiopathology of discal pain. The techniques of image-guided spinal periradicular infiltration and percutaneous nucleotomy with laser and radiofrequency are presented with emphasis on their best indications.

    Patients with approved workers' compensation injuries receive guaranteed compensation for the duration of their injury, whereas patients with personal injury claims are only compensated, if at all, at the time of a successful settlement or trial verdict at a time point distant from their injury. This study compares the financial impact and loss of work patterns due to a workers' compensation (WC) claim or personal injury in patients with a symptomatic cervical disc herniation resulting from a motor vehicle collision. A prospective study of patients who were seen by a single spine specialist between 1/2/96 and 9/1/01. A consecutive evaluation of 531 patients who were treated for a cervical pain syndrome caused by a motor vehicle collision. Mechanism of injury and insurance type, ie, workers' compensation or personal injury, was recorded for each patient as well as treatment response and return to work patterns. The data were analyzed using the two-way Z test. All patients were managed in a similar manner with noninvasive treatment initially, followed by injections, and finally surgical intervention in those who failed conservative measures. Return to work rates and work disability were determined at either final follow-up or at the last doctor's visit before loss to follow-up. 270 of 531 patients were diagnosed with a symptomatic one or two level disc herniation by a cervical magnetic resonance imaging scan. Fifty-four patients were insured through the workers' compensation board, and 216 reported their crash as a personal injury claim. In the WC group the work disability at 3 months follow-up revealed a cumulative 2,262 total lost days of work (average 37.1 days per person). At the point of maximal medical improvement (MMI) or 2-year follow-up, total days lost from work were 7,107 (average 131.6 days per person.) In the personal injury non-WC group, the 3-month follow-up of lost days of work was 1,093 days (average 5.1 days per person.) At 2 years follow-up, the

    The aim of this study was to compare the efficiency of different surgical approaches to thoracic disc herniation, and to show the role of segmental fusion and selection of an appropriate microsurgical decompression technique for the successful outcome of surgery. A group of 27 patients, 10 men and 17 women, between 31 and 70 years (average age, 49.33 years) were included in this prospective study. They underwent surgery for thoracic degeneration disc disease in the period from June 1994 to August 2008. In all patients, the severity of myelopathy was assessed using the grading Frankel system and JOA score, axial and radicular pain intensity was evaluated with VAS and ODI rating systems. The diagnosis was established on the basis of thoracic spine radiography, thoracic spine MRI and a CT scan of the segment. A total of 30 thoracic segments, in the range of Th4/Th5 to Th12/L1, were indicated for surgery. Localisation of the hernia was medial at 19 segments, mediolateral at three and lateral at eight segments. Soft disc herniation was found in 17 cases and hard disc protrusion at the remaining 13 segments. Surgery for significant myelopathy was carried out in 23 patients and for pain in four patients. According to the surgical procedure used, the patients were allocated to two groups: group A comprised 10 patients treated without disc replacement through a laminectomy or a costotransversectomy exposure, and group B consisted of 17 patients undergo- ing intersomatic fusion via a thoracotomy. Clinical and radiographic examinations were made at regular intervals for at least 1 year of follow-up. The results of clinical assessment, including JOA scores, JOA Recovery Rate, VAS scores at rest and after exercise and ODI, were statistically analysed for each group and compared. There was a statistically significant difference in JOA evaluation of myelopathy between the groups in group A, the mean JOA score declined from 7.9 to 7.0, i.e., -0.9 point, while in group B it

    The CT appearance of the lumbar neural foramina and contents is described in detail and compared to histopathological specimens. Direct axial scans with secondary sagittal, coronal and paraxial reconstruction series of slices of the neuralforamen were derived from lumbar spine examination of fifty normal adults. These normal parameters were then used to evaluate and subdivide 20 patients with disc herniation involving the neuralforamen. The new paraxial reformation was able to show an intraneuroforaminal disc involvement. CT-reformation technique and operative results in intraneuroforaminal disc herniation correspond in 80%. This improvement in preoperative diagnosis demonstrates to the neurosurgeon the full extent of disc herniation and results in an optimized operative approach. (orig.)

    Among the patients operated because of lumbar disc herniation from January 1973 to May 1979 at Korea University Hospital, 154 cases were analyzed radiologically and the following conclusions were obtained. 1. The ratio of male to female was 1.96 : 1. 2. The incidences of single and multiple involvement were 74.7% and 25.3%. 3. Most frequent level of lumbar disc herniation was L4-5 interspace. 4. The incidences of left, central and bilateral defects were 45.45%, 33.76%, 12.33% and 8.44% respectively. 5. The incidences of spina bifida and transitional vertebra were 24.04% and 9.09% respectively. 6. The overall mean of the lumbosacral angle was 33.97 .deg. 7. The overall mean depth of the lumbar lordosis was 8.48 mm. 8. The ratio of the height of L4-5 interspace to the shorter anteroposterior diameter of L-5 body was obtained by authors' idea. The mean ratios of male and female patients of L4-5 disc herniation which had no evidence of the narrowing of L4-5 interspace on simple radiologic finding were 0.3042 and 0.3064 respectively. So the ratio had a little value in the diagnosis of L4-5 disc herniation on simple radiologic study. 9. Myelography had high diagnostic accuracy, and the majority of the pseudonegative finding on lumbar disc herniation myelographically was seen at L4-5 disc herniation.

    A CT study was carried out on 43 patients with low back pain and sciatica who were treated conservatively. They were followed up for over 20 months (mean) clinically and monitored by CT before and after treatment. Initially, 38 of them had herniation and 5 had protrusion of the disc. At the time of follow-up only 24 of the initial 40 patients still had neurological deficits. In 76.7% of the patients CT showed an improvement (clear regression in 15 patients, moderate decrease in 18 patients). A favourable tendency towards regression was observed in disc herniation at the L5-S1 level and in cases showing sequestration. The prognosis was unfavourable in herniations at higher levels than L5-S1 and in lateral herniation reaching the intervertebral foramen. (orig.) [de

    A 48-year-old woman with the C5/6 disc herniation was reported. She had noticed vague pains in the left shoulder a half year earlier. Neurological examination showed left lower cervical radicular pains and incomplete Brown-Sequard syndrome of the same side. The disc herniation was diagnosed by myelography and discography. On the CT examination, surprisingly, the prolapsed disc was homogenously enhanced after the administration of intravenous contrast medium. The vertebral angiography showed increased vascularity behind the C5/6 intervertebral space. At operation, a prolapsed nucleus pulposus with proliferated connective tissue was found and curetted. The etiology of contrast enhancement was discussed. (author)

  2. Can repeat injection provide clinical benefit in patients with cervical disc herniation and stenosis when the first epidural injection results only in partial response?

    Lee, Jung Hwan; Lee, Sang-Ho

    2016-07-01

    Epidural steroid injection (ESI) is known to be an effective treatment for neck or radicular pain due to herniated intervertebral disc (HIVD) and spinal stenosis (SS). Although repeat ESI has generally been indicated to provide more pain relief in partial responders after single ESI, there has been little evidence supporting the usefulness of this procedure. The purpose of this study, therefore, was to determine whether repeat ESI at a prescribed interval of 2 to 3 weeks after the first injection would provide greater clinical benefit in patients with partial pain reduction than intermittent ESI performed only when pain was aggravated. One hundred eighty-four patients who underwent transforaminal ESI (TFESI) for treatment of axial neck and radicular arm pain due to HIVD or SS and could be followed up for 1 year were enrolled. We divided the patients into 2 groups. Group A (N = 108) comprised partial responders (numeric rating scale (NRS) ≥ 3 after the first injection) who underwent repeat injection at a prescribed interval of 2 to 3 weeks after the first injection. Group B (N = 76) comprised partial responders who did not receive repeat injection at the prescribed interval, but received intermittent injections only for aggravation of pain. Various clinical data were assessed, including total number of injections during 1 year, NRS duration of Group A, or after first injection in Group B (time to reinjection). Groups A and B were compared in terms of total population, HIVD, and SS. In the whole population, HIVD subgroup, and SS subgroup, patients in Group A required significantly fewer injections to obtain satisfactory pain relief during the 1-year follow-up period. Group A showed a significantly longer time to reinjection and longer NRS Group B did. Repeat TFESI conducted at 2- to 3-week intervals after the first injection in partial responders contributed to greater clinical benefit compared with intermittent TFESI performed only upon pain

    The Gd-DTPA-enhanced magnetic resonance findings in two patients with herniated thoracic intervertebral discs are reported. The first patient was a 56-year-old woman with a small subligamentous T6-7 disc herniation, slightly lateralized to the right. The second patient was a 51-year-old man with a central and right posterolateral disc herniation, including a large calcified fragment, at the T8-9 level. The nonenhanced MR examination revealed the presence of an extradural mass lesion in both patients, impinging upon the dural sac and compressing and displacing the spinal cord posteriorly. The lesion was slightly hypointense on both T1- and T2-weighted spin echo sequences. Following intravenous injection of Gd-DTPA in a dosage of 0.1 mmol/kg body weight, enhancement of the posterior longitudinal ligament was noted and triangular areas of contrast uptake were seen to occur in the epidural space above and below the herniated disc. At surgery, they were found to correspond to dilated and congested epidural veins. (orig.)

    To assess the frequency, location, associated MR findings, and clinical symptoms of the high level lumbar disc herniation(HLDH). A total of 1076 patients with lunbar disc herniation were retrospectively reviewed. MR images of 41 of these with HLDH(T12-L1, L1-2, L2-3) were analysed in terms of frequency, location, and associated MR findings, and correlated with clinical symptoms of HLDH. The prevalence of HLDH was 3.8%(41/1076). HLDH was located at T12-L1 level in four patients(10%), at L1-2 level in 14(34%), at L2-3 level in 21(51%), and at both L1-2 and L2-3 levels in two. The age of patients ranged from 20 to 72 years (mean, 44), and there were 26 men and 16 women. In 11(27%), whose mean age was 32 years, isolated disc herniation was limited to these high lumbar segments. The remaining 30 patients had HLDH associated with variable involvement of the lower lumbar segments. Associated lesions were as follow : lower level disc herniation(14 patients, 34%); apophyseal ring fracture(8 patients, 19%); Schmorl's node and spondylolisthesis (each 6 patients, each 14%); spondylolysis(3 patients, 7%); and retrolisthesis(2 patients, 5%). In 20 patients(49%) with HLDH(n=41), there was a previous history of trauma. Patients with HLDH showed a relatively high incidence of associated coexisting abnormalities such as lower lumbar disc herniation, apophyseal ring fracture, Schmorl's node, spondylolysis, and retrolisthesis. In about half of all patients with HLDH there was a previous history of trauma. The mean age of patients with isolated HLDH was lower; clinical symptoms of the condition were relatively nonspecific and their incidence was low

    To assess the frequency, location, associated MR findings, and clinical symptoms of the high level lumbar disc herniation(HLDH). A total of 1076 patients with lunbar disc herniation were retrospectively reviewed. MR images of 41 of these with HLDH(T12-L1, L1-2, L2-3) were analysed in terms of frequency, location, and associated MR findings, and correlated with clinical symptoms of HLDH. The prevalence of HLDH was 3.8%(41/1076). HLDH was located at T12-L1 level in four patients(10%), at L1-2 level in 14(34%), at L2-3 level in 21(51%), and at both L1-2 and L2-3 levels in two. The age of patients ranged from 20 to 72 years (mean, 44), and there were 26 men and 16 women. In 11(27%), whose mean age was 32 years, isolated disc herniation was limited to these high lumbar segments. The remaining 30 patients had HLDH associated with variable involvement of the lower lumbar segments. Associated lesions were as follow : lower level disc herniation(14 patients, 34%); apophyseal ring fracture(8 patients, 19%); Schmorl's node and spondylolisthesis (each 6 patients, each 14%); spondylolysis(3 patients, 7%); and retrolisthesis(2 patients, 5%). In 20 patients(49%) with HLDH(n=41), there was a previous history of trauma. Patients with HLDH showed a relatively high incidence of associated coexisting abnormalities such as lower lumbar disc herniation, apophyseal ring fracture, Schmorl's node, spondylolysis, and retrolisthesis.

    Low back pain with or without lower extremity pain is the most common problem among chronic pain disorders with significant economic, social, and health impact. This study was conducted to determine the frequency of lumbar disc herniation and its different levels, among patients with chronic backache. This cross sectional study was conducted in the department of Neurosurgery, Ayub Medical College Abbottabad from January 2011 to January 2013. All the patients presenting with chronic low backache of either gender above the age 14 years were included in the study. Magnetic resonance imaging (MRI) was done in all the patients included in the study to look for lumbar disc herniation. A total of 477 patients with chronic low backache were included in the study out of which 274 (57.4%) were males. Age of the patients ranged from 19 to 75 (39.92 +/- 12.31) years. Out of 477 patients 38 (7.9%) had significant radiological evidence of disc prolapse at lumbar vertebral levels, with 26 (9.5%) males and 12 (5.9%) females. Among these 38 patients with inter-vertebral disc, 20 (52.6%) of patients had disc herniation at L5-S1, 15 (39.5%) at L4-L5, 2 (5.26%) cases at L3-L4 level and only one case (2.6%) had the involvement of L2-L3 level. No cases of L1-L2 disc prolapse were found. Patients with chronic backache can have inter-vertebral lumbar disc prolapsed disease. Middle age group are more affected by lumbar disc disease especially at the lower lumbar regions.

    1999-01-01

    In the cases which had surgery after enhanced MRI, prolapsed form of hernia and the usefulness of enhanced MRI were examined. The patients were 13 males (14 intervertebral discs) and 5 females (6 intervertebral discs) with lumber disc herniation. The lumber disc herniation was classified into 3 types reference to Macnab's classification; SE (protrusion and subligamentous extrusion), TE (transligamentous extrusion) and SEQ (sequestration). Prolapsed forms were identified in 20 intervertebral discs. Enhanced MRI showed positive in 9 intervertebral discs (SE 1, TE 4 and SEQ 4) and showed negative in 11 discs (SE 10 and TE 1). As for the period from development to enhanced MRI, the significant difference wasn't recognized between positive group and negative group. The diagnostic rate of enhanced MRI was 88.9% (8/9) in sensitivity, 90.9% (10/11) in specificity and 90.0% (18/20) in accuracy. In enhanced MRI, engorged epidural venous plexus was also imaged, and minute change as only annular tear couldn't be detected. Looking from 2 directions crossing at right angles, the effect of contrast enhancement should be judged. (K.H.)

    Full Text Available Objective:To associate spinopelvic parameters, pelvic incidence, sacral slope, pelvic tilt and lumbar lordosis with the axial location of lumbar disc herniation.Methods:Retrospective study, which evaluated imaging and medical records of 61 patients with lumbar disc herniation, who underwent surgery with decompression and instrumented lumbar fusion in only one level. Pelvic incidence, sacral slope, pelvic tilt and lumbar lordosis with simple lumbopelvic lateral radiographs, which included the lumbar spine, the sacrum and the proximal femur. The affected segment was identified as the level and location of lumbar disc herniation in the axial plane with MRI scans.Results:Of 61 patients, 29 (47.5% had low lumbar lordosis; in this group 24 (82.8% had central disc herniation, 4 (13.8% had lateral recess disc herniation and 1 (3.4% had extraforaminal disc herniation (p<0.05. Of the 61 patients, 18 (29.5% had low sacral slope; of this group 15 (83.3% had central disc herniation and 3 (16.7% had disc herniation in lateral recess (p<0.05.Conclusions:There is a trend towards greater load distribution in the anterior region of the spine when the spine has hypolordotic curve. This study found an association between low lordosis and central disc herniation, as well as low sacral slope and central disc herniation.

  10. Huge Intracanal lumbar Disc Herniation: a Review of Four Cases

    Farzad Omidi-Kashani

    2016-01-01

    Full Text Available Lumbar disc herniation (LDH is the most common cause of sciatica and only in about 10% of the affected patients, surgical intervention is necessary. The side of the patient (the side of most prominent clinical complaints is usually consistent with the side of imaging (the side with most prominent disc herniation on imaging scans. In this case series, we presented our experience in four cases with huge intracanal LDH that a mismatch between the patient’s side and the imaging’s side was present. In these cases, for deciding to do the operation, the physicians need to rely more on clinical findings, but for deciding the side of discectomy, imaging characteristic (imaging side may be a more important criterion.

    Lumbar disc herniation is a common surgical spine pathology that may be presented during pregnancy. The state of pregnancy complicates the diagnosis and therapeutical management of this entity. Specific considerations rule the decision for surgical intervention, the optimal timing of it and the type of selected procedure in a pregnant patient, due to the potential risks for the fetus. In the last 30 years, evolution in the field of spine surgery has provided options other than open standard discectomy. The well-established concept of "minimal intervention" has led to the development of microdiscectomy and other innovative, full-endoscopic techniques for lumbar discectomy. The aim of the present study is to review the surgical management of lumbar disc herniation in pregnancy and investigate the potential role of minimally invasive spine surgery in this specific population.

    To determine the association of pre-operative assessment of MRI findings, neurological status and symptoms with postoperative Cloward surgical outcome in cervical disc prolapse. Descriptive study. The Neurosurgery Department of Jinnah Postgraduate Medical Centre (JPMC), Karachi, from May 2008 to May 2009. Patients presenting with neck pain, brachialgia, limb weakness and spasticity were clinically examined for pre-operative neurological status of power, reflexes and sensation. The exclusion criteria were, cervical disc prolapsed patients, planned for smith-Robinson and micro-discectomy, traumatic cervical disc prolapse and cervical spondylosis. Neuroradiological investigations included cervical spine X-rays and MRI. All patients were surgically treated for cervical prolapsed intervertebral disc with anterior cervical discectomy and interbody fusion with Cloward technique. Postoperative neck immobilization was done with cervical collar for 7-8 weeks. Drain was removed on first postoperative day while check plain cervical X-rays were taken on third day. Results were analysed using chi-square test with significance at p cervical disc prolapse were C 5-6 (43.3%) and C 6-7 (23.3%); 26 (86.6%) patients had disc herniation causing thecal effacement with cord compression and 04 (13.3%) patients showed ischemia of cord. Single-level Cloward surgery done in 26 (86.3%) patients while two-level Cloward surgery performed in 04 (13.3%) only. About 83.3% patients improved and 13.3% did not while 01 patient was re-operated. No complications and mortality was related to the surgical procedure. Statistically different variables identified, related to outcome were pre-operative neurological status (p=0.001) and spinal cord involvement on MRI (p=0.001). Cloward technique for cervical disc prolase was simple and safe surgical procedure with favourable results and few complications; 100% fusion occurred after Cloward surgery, even without instrumentation. Outcome was significantly

  13. CT findings of lumbar intervertebral disc: II. Disc herniation (HNP)

    Yang, W. J.; Lee, J. M.; Bahk, Y. W.

    1984-01-01

    In lumbar region the epidural fat pad is relatively abundant so that CT can provides sufficient information in diagnosis of lumbar HNP. Many authors have reported on the CT findings of HNP such as focal nodular protrusion of the posterior disc margin, obliteration of epidural fat pad, impingement of dural sac and nerve root, swelling of nerve root, soft tissue density in the spinal canal and calcification of disc. However there was so previous report describing incidence and reliability of the findings. It is the purpose of the present study to survey the frequency, reliability, and limitation of these CT findings. The clinical material was consisted of 30 operatively proven cases of HNP of the lumbar spine. Each lumbar CT scan was reviewed retrospectively and the findings were analysed by two radiologists independently. There were 20 males and 10 females and the mean age was 36.7 years. Involvement of L4-S5 level was 2.3 times more frequent than that of L5-S1 level. Of 30 cases, 22 were unilateral posterolateral types and 8 cases central or unilateral far lateral types. CT findings observed were nodular protrusion of the posterior margin of the disc, obliteration of epidural fat pad, impingement of dural sac or nerve root, soft tissue density in the spinal canal and calcification in the posterior portion of the protruded disc, in order of decreasing frequency. The conclusions are follows: 1. Nodular protrusion of the posterior disc margin accompanied by obliteration of epidural fat pad was observed in every case. The former findings was designated as direct sign and the latter indirect. 2. Obliteration of the epidural fat appears to be significant in lateral recesses especially when it occurs unilaterally. This was not true, however, in the centrally located fat pad. 3. Impingement of the dural sac and nerve root were observed in 90% and 67%, respectively, and were very helpful in establishing HNP diagnosis when the direct and indirect signs were equivocal

    paciente con síndrome de Brown-Séquard por hernia de disco cervical.This article presents a case in which Brown-Séquard syndrome resulted from a double level cervical disc herniation. A 40-year-old man without previous history of cervical pathology, presented with insidious right arm and leg paresis associated with associated with decreased pain and thermal sensitivity in the left hemibody after diving which caused indirect trauma of the cervical spine. Magnetic resonance imaging of the cervical spine showed double level disc herniation in C4-C5 and C5-6 with compression of the right half of spinal cord and hyperintensity in T2-weighted images. After a complete decompression of neural structures, a double level interbody fusion was performed. There was partial recovery of neurological status after a long period of physical therapy. Early surgical intervention and prompt rehabilitation are paramount to achieve neurological recovery in patients with Brown-Séquard syndrome resulting from a cervical disc herniation.

  15. Effect of Age and Lordotic Angle on the Level of Lumbar Disc Herniation

    2011-01-01

    Full Text Available It has been previously suggested in the literature that with aging, degenerative changes as well as disc herniation start at the lower lumbar segments, with higher disc involvement observed in an ascending fashion in older age groups. We conducted a study to investigate this correlation between age and level of disc herniation, and to associate it with the magnitude of the Lumbar Lordotic Angle (LLA, as measured by Cobb’s method. We followed retrospectively lumbosacral spine MRI’s of 1419 patients with symptomatic disc herniation. Pearson’s correlation was used in order to investigate the relationship between LLA, age, and level of disc herniation. Student’s -test was applied to assess gender differences. Young patients were found to have higher LLA (=0.44, <0.0001 and lower levels of disc herniation (=0.302, <0.0001, whereas older patients had higher level herniation in lower LLA group (mean LLA 28.6° and 25.4° and lower level herniation in high LLA group (mean LLA 33.2°. We concluded that Lumbar lordotic Cobb’s angle and age can be predictors of the level of lumbar disc herniation. This did not differ among men and women (=0.341, <0.0001.

    1985-03-01

    In this study the effectiveness of computed tomographic discography (CTD) in diagnosing cervical soft disc hernia was evaluated. Twenty-five intervertebral discs of 15 cases with cervical soft disc hernia were examined with a discography and then a CT scan. Results of the CT scan were as follows: three discs were protruded, 12 discs were prolapsed, 6 discs were extruded, and 4 discs were sequestrated. The findings were helpful in determining the location of soft disc hernias between the median and posterolateral discs. They were also valuable in classifying types of hernias and surgical approaches.

    2014-04-01

    Technical case report. To describe the novel technique of percutaneous endoscopic herniotomy using a unilateral intra-annular subligamentous approach for the treatment of large centrally herniated discs. Open discectomy for large central disc herniations may have poor long-term prognosis due to heavy loss of intervertebral disc tissue, segmental instability, and recurrence of pain. Six consecutive patients who presented with back and leg pain, and/or weakness due to a large central disc herniation were treated using percutaneous endoscopic herniotomy with a unilateral intra-annular subligamentous approach. The patients experienced relief of symptoms and intervertebral disc spaces were well maintained. The annular defects were noted to be in the process of healing and recovery. Percutaneous endoscopic unilateral intra-annular subligamentous herniotomy was an effective and affordable minimally invasive procedure for patients with large central disc herniations, allowing preservation of nonpathological intradiscal tissue through a concentric outer-layer annular approach.

    A prospective cross-sectional case series study. To investigate the prevalence of low virulence disc infection and its associations with characteristics of patients or discs in the cervical spine. Low virulence bacterial infections could be a possible cause of intervertebral disc degeneration and/or back pain. Controversies are continuing over whether these bacteria, predominantly Propionibacterium acnes (P. acnes), represent infection or contamination. However, the current studies mainly focus on the lumbar spine, with very limited data on the cervical spine. Thirty-two patients (20 men and 12 women) who underwent anterior cervical fusion for degenerative cervical spondylosis or traumatic cervical cord injury were enrolled. Radiological assessments included X-ray, CT, and MRI of the cervical spine. Endplate Modic changes, intervertebral range of motion, and disc herniation type were evaluated. Disc and muscle tissues were collected under strict sterile conditions. Samples were enriched in tryptone soy broth and subcultured under anaerobic conditions, followed by identification of the resulting colonies by the PCR method. Sixty-six intervertebral discs were excised from thirty-two patients. Positive disc cultures were noted in eight patients (25%) and in nine discs (13.6%). The muscle biopsy (control) cultures were negative in 28 patients and positive in 4 patients (12.5%); three of whom had a negative disc culture. Seven discs (10.6%) were positive for coagulase-negative Staphylococci (CNS) and two discs were positive for P. acnes (3.0%). A younger patient age and the extrusion or sequestration type of disc herniation, which represented a complete annulus fibrous failure, were associated with positive disc culture. Our data show that CNS is more prevalent than P. acnes in degenerative cervical discs. The infection route in cervical discs may be predominantly through an annulus fissure. Correlation between these infections and clinical symptoms is uncertain

  20. Suspected herniated lumbar disc - computed tomography in differential diagnosis of non-disc-related sciatica

    Weiss, T.; Koehler, D.; Treisch, J.; Claussen, C.; Felix, R.

    1984-01-01

    The most common reason a patient is referred for spinal CT examination is to exclude a ruptured intervertebral disc. Besides nerve root entrapment due to herniated disc, a number of unusual for unexpected conditions have been encountered in the course of CT lumbar spine studies. These include spondylolisthesis, spinal dysraphism, Paget's disease, and inflammatory, neoplastic, or metastatic lesions. The application of spinal (small-circle) target imaging includes the risk to overlook soft tissue lesions that extend beyond the reconstruction circle. Therefore, complete (large-circle) circumferential abdominal scanning is recommended in case of a suspected extraspinal cause of sciatica. (orig.) [de

    Full Text Available Low back pain is one of the prevalent diseases of the world. In this research, with helping of MRI the incidence of disc herniation in patients of low back pain in our living area was studied. Survey of the specifications of disc herniation was carried out and data was compared with some performed studies in other parts of the world. In this study, for 600 patients referred to HAMEDAN MRI CENTER, who had complaint of low back pain, MRI study was performed. Then, MRI Images of the patients who had disc hernition, studied for number, form, severity and anatomic position of the herniated disc and family history of low back pain. 83.7% of the studied cases was pathologic and 16.3% was normal. Among the pathologic cases, 70.12% had disc herniation. The most common age group in both sex for disc herniotion was 30-50 years. Disc herniation in men was more common than women. The most common anatomic position of the herniated disc was L4- L5 disc, mostly was one herniated disc and centrolateral form. There was not any meaningful relation between family history of the low back pain and lumbar disc herniation. This study showed that lumbar disc herniation is one of the common causes of the low back pain in our living area and MRI is the choice imaging modality for diagnosis and survey of low back pain and disc herniation.

    Although disc injury is common in cervical spinal fractures the mechanism of disc herniation in cervical fracture dislocations is not known. This study evaluated the pathogenesis of disc hernia in cervical fracture dislocations. Twenty-two patients who underwent anterior and posterior spinal fixation were studied. Findings of preoperative magnetic resonance imaging (MRI) were compared with surgical findings. During surgery, cervical disk hernia were found in six patients (27 %), and the MRI finding of these patients were evaluated in detail. We concluded that the characteristic MRI findings of cervical disc hernia are as follows: 1) discontinuity of injured disc, 2) anterior indentation of spinal cord at the site of dislocated vertebral body, and 3) signal irregularity at the site of interspace between dislocated vertebral body and spinal cord.

  7. Genotypic and antimicrobial characterisation of Propionibacterium acnes isolates from surgically excised lumbar disc herniations

    Rollason, Jess; McDowell, Andrew; Albert, Hanne B

    2013-01-01

    The anaerobic skin commensal Propionibacterium acnes is an underestimated cause of human infections and clinical conditions. Previous studies have suggested a role for the bacterium in lumbar disc herniation and infection. To further investigate this, five biopsy samples were surgically excised...... from each of 64 patients with lumbar disc herniation. P. acnes and other bacteria were detected by anaerobic culture, followed by biochemical and PCR-based identification. In total, 24/64 (38%) patients had evidence of P. acnes in their excised herniated disc tissue. Using recA and mAb typing methods...... isolate collection (63%) suggests that the role of P. acnes in lumbar disc herniation should not be readily dismissed....

    Objective: To study the clinical effect and the range of indications of oxygen-ozone treatment for lumber disc herniation. Methods: 6-15 ml of oxygen-ozone (35-45 μg/ml) were injected percutaneously into lumbar disc. In case of multiple disc herniations, the procedure could be taken with two discs for once. Results: 323 patients with 433 discs were treated by oxygen-ozone injection procedure. Total effective rate was 77.7%. Conclusions: The treatment of lumber disc herniation by oxygen-ozone injection is simple, safe and effective with mild trauma. Oxygen-ozone not only can oxidize the proteoglycan in the nucleus leading to the contraction of nucleus, but also provide anti-inflammation effect with pain relief and without complication yet.

    2013-01-01

    Cranial thoracic intervertebral disc herniations have been reported to be rare in dogs due to the presence of the intercapital ligament, however some studies have proposed they may not be uncommon in German Shepherd dogs. The purpose of this retrospective study was to compare cranial thoracic intervertebral disc herniations in German Shepherd dogs and other large breed dogs (control group). Medical records at the Ontario Veterinary College were searched for German Shepherd dogs and other large breed dogs that had magnetic resonance imaging studies including the T1-T9 region. For each dog and each disc space from T1-T9, three variables (compression, disc degeneration, and herniation) were recorded and graded based on review of sagittal T2-weighted images. Twenty-three German Shepherd dogs and 47 other large breed dogs met inclusion criteria. The German Shepherd dog group had higher scores than the control group for compression (P = 0.0099) and herniation (P dog group, intervertebral discs T2-T3 and T4-T5 had an increased risk for compression and T3-T4 had an increased risk for compression and herniation. Findings from this study indicated that German Shepherd dogs may be more likely than other large breed dogs to have spinal cord compression due to cranial thoracic disc herniations. Imaging of the cranial thoracic spine, including T2-T3, is recommended for German Shepherd dogs with T3-L3 neurological signs. © 2012 Veterinary Radiology & Ultrasound.

    Full Text Available A hérnia discal lombar é o diagnóstico mais comum dentre as alterações degenerativas da coluna lombar (acomete 2 a 3% da população e a principal causa de cirurgia de coluna na população adulta. O quadro clínico típico inclui lombalgia inicial, seguida de lombociatalgia e, finalmente, de dor ciática pura. A história natural da hérnia de disco é de resolução rápida dos sintomas (quatro a seis semanas. O tratamento inicial deve ser conservador, com manejo medicamentoso e fisioterápico, podendo ser acompanhado ou não por bloqueios percutâneos radiculares. O tratamento cirúrgico está indicado na falha do controle da dor, déficit motor maior que grau 3, dor radicular associada à estenose óssea foraminal ou síndrome de cauda equina, sendo esta última uma emergência médica. Uma técnica cirúrgica refinada, com remoção do fragmento extruso, e preservação do ligamento amarelo, resolve a sintomatologia da ciática e reduz a possibilidade de recidiva em longo prazo.Lumbar disc herniation is the most common diagnosis amongst the degenerative conditions of the lumbar spine (affecting around 2 to 3% of the population, and is the principal cause of spine surgery in the adult population. The typical clinical picture includes initial lumbalgia, followed by progressive sciatica. The natural history of disc herniation is one of rapid resolution of the symptoms (from 4-6 weeks. Early treatment should be conservative, with pain management and physiotherapy, sometimes associated with selective nerve root block. Surgery should be considered if pain management is unsuccessful, if there is a motor deficit (strength grade 3 or less, where there is radicular pain associated with foraminal stenosis, or in the presence of cauda equina syndrome, the latter representing a medical emergency. A refined surgical technique, with removal of the extruded fragment and preservation of the ligamentum flavum, resolves the sciatic symptoms and reduces

    The authors retrospectively reviewed the relation between the location of disc herniation and pre- and postoperative changes in sciatic scoliotic list in 40 patients with surgically confirmed lumbar disc herniation who had sciatic scoliotic list with postoperative recovery. Clinical factors associated with scoliosis also were included. To evaluate the significance and pathomechanism of sciatic scoliotic list. The proposed causes of lumbar sciatic scoliosis mainly imply an alleviation of nerve root irritation in relation to the anatomic location of disc herniation relative to the nerve root. The pre- and postoperative serial Cobb angle between L1 and L5 in anteroposterior lumbar radiographs in the standing position were measured. The relation between the convex side of scoliosis and clinical parameters in terms of the side of symptoms, age, gender, duration of low back pain or leg pain, the angle of a positive straight leg raising test, and the time required for recovery of sciatic scoliosis were investigated. In addition, magnetic resonance imaging also was performed in five recent cases from 40 patients. The average Cobb angle decreased from 10.7 degrees to 2.7 degrees within an average of 7.5 months after surgery. The preoperative Cobb angle of patients with disc herniation medial to the nerve root was significantly higher than that just beneath or lateral to the nerve root. Thirty-two of 40 patients (80.0%) had a lumbar disc herniation at the convex side of scoliosis, irrespective of the transverse location of the herniation. The time required for scoliosis disappearance in disc herniation located lateral to the nerve root tended to be longer than that for other types of disc herniation. Magnetic resonance imaging through the paramedian planes showed enlargement of the intervertebral foramen at the convex side of scoliosis, compared with that at the concave side in five recent cases from the current study. These results suggest that sciatic scoliotic list is not

    To evaluate the relationship between MR changes of the nucleus pulposus and the time interval after traumatic disc herniation. T2-weighted MR images of 132 patients with back pain and/or sciatica were reviewed. The changes of signal intensity, central cleft and height of the nucleus pulposus were used as criteria of disc degeneration and they were graded as normal, mild, moderate and severe degree of degeneration. Putting these criteria together we provided integrated grade of degeneration of the nucleus pulposus(grade 0-3). To get the preliminary data for normal and age-related disc degeneration, we measured the disc height by age groups and disc levels and analyzed the relationship between the age of the patients and the signal intensity, cleft and height in normal disc levels of the 132 patients. In 68 patients of 88 levels disc herniation, we analyzed the relationship between symptom duration and the degree of degeneration. Among these 68 patients we selected 14 patients(16 levels) who were under 30 years of age and had history of recent trauma to minimize data distortion from age related degeneration and ambiguity of initiation point of degeneration. In this group we analyzed the relationship between the time period after traumatic disc herniation and the degree of degeneration. The age of the patient had close relationship with the grade of signal intensity, central cleft, and disc height and grade of degeneration of the nucleus pulposus in normal discs. In 88 levels of herniated discs, the duration of symptom and degree of degeneration showed moderate correlation. In 14 patients of disc herniation who were under 30 years old and had trauma history in recent 2 years, grade 1 disc degeneration occurred in average 3.7 months after trauma. Although it was difficult to proceed statistical analysis in the last group because of small patients number, the degree of degeneration of nucleus pulposus had close relationship with the duration after traumas or duration of

  15. A new method for lumbar herniated inter-vertebral disc diagnosis based on image analysis of transverse sections.

    Tsai, Ming Dar; Jou, Shyan Bin; Hsieh, Ming Shium

    2002-01-01

    This paper describes an image analysis method that uses automatic algorithms for the evaluation of herniation classification and geometry in the diagnosis of lumbar herniated inter-vertebral disc (HIVD). The method uses boundary approximation that uses a B-spline curve to approximate circle-like disc boundary and excludes the herniation from other normal parts of the disc boundary and, feature recognition that classifies the herniation, and herniation shape reconstruction that infers the 3D geometry from one or more transverse sections. This method can be used as a qualitative and quantitative tool for the diagnosis of lumbar HIVD using transverse sections.

    The CT discographic findings of 56 discs in 43 patients with low-back and/or leg pain were evaluated mainly from the clinical standpoint including pain provocation during the injection of the contrast material, correlation between the type of the herniation and symptoms and clinical course after the examination. The clinical value of CT discography is controversial, but it is well recognized that CT discography is the diagnostic method of choice for equivocal situations as patients showing negative myelography and significant symptoms and for the preoperative evaluation of patient thought to have the extreme lateral disc herniation. Exact provoked pain response was noted in 72 % of 43 pathologic discs and almost all discs especially in patients showing positive SLR test at less than 70 deg. So this pain response seems to provide additional information indicating the true pathologic disc level. Sciatic pain in the legs was much more frequently seen in the paramedian or lateral type herniation, but there was no relation between low-back pain and central type herniation. Majority of either type of disc herniation showed both low-back and leg pains. This suggests that clinical symptoms are based on not only disc herniation but also disc degeneration itself. We injected steroid (4 mg of Decadron) and local anesthetic (1 ml of 1 % Carbocain) into the disc after the examination for the purpose of improving the clinical symptoms as the first attempt. Definite improvement of various degree was noted in 56 % of total 43 cases after the procedure and CT discography was thought to be a valuable method of diagnosis in proper indications despite risky needle puncture.

    Study design: Descriptive study comparing MRI classifications with measurements from radiographs. Objectives: 1.Define the relationship between MRI classified cervical disc degeneration and objectively measured disc height. 2.Assess the level of inter- and intra-observer errors using MRI in defining cervical disc degeneration. Summary of background data: Cervical spine degeneration has been defined radiologically by loss of disc height, decreased disc and bone marrow signal intensity and disc protrusion/herniation on MRI. The intra- and inter-observer error using MRI in defining cervical degeneration influences data interpretation. Few previous studies have addressed this source of error. The relation and time sequence between cervical disc degeneration classified by MRI and cervical disc height decrease measured from radiographs is unclear. Methods: The MRI classification of degeneration was based on nucleus signal, prolaps identification and bone marrow signal. Two neuro-radiologists evaluated the MR-images independently in a blinded fashion. The radiographic disc height measurements were done by a new computer-assisted method compensating for image distortion and permitting comparison with normal level-, age- and gender-appropriate disc height. Results/conclusions: 1.Progressing disc degeneration classified from MRI is on average significantly associated with a decrease of disc height as measured from radiographs. Within each MRI defined category of degeneration measured disc heights, however, scatter in a wide range. 2.The inter-observer agreement between two neuro-radiologists in both defining degeneration and disc height by MRI was only moderate. Studies addressing questions related to cervical disc degeneration should take this into consideration.

    Professional basketball players are at risk for lumbar disc herniation (LDH), yet the evidence guiding treatment after operative or nonoperative management of this condition in the National Basketball Association (NBA) is limited. NBA players with LDH will have different performance outcomes based on treatment type. Case-control study. Level 4. Athletes in the NBA with an LDH were identified through team injury reports, transaction records, and public sports archives. A 1:2 case-control study was performed in which LDH players and players without LDH were matched for player variables. Statistical analysis was employed to compare pre- and postindex season performance (games played and player efficiency rating [PER]) and career longevity between test subjects and controls in the operatively treated (OT) and nonoperatively treated (NOT) cohorts. A total of 61 NBA players with LDH were included, of whom 34 underwent discectomy and 27 were managed nonoperatively. Return-to-play (RTP) rates did not differ between NOT and OT players (77.8% vs. 79.4%). When compared with controls, OT players played significantly fewer games and had a lower PER than controls during the first postoperative season, but no difference was seen 2 and 3 years after surgery, with no difference in postoperative career length. In contrast, no difference in games played or PER was seen between NOT players and controls, although NOT players played significantly fewer postindex seasons. NBA players have a high RTP rate regardless of type of treatment for LDH; however, postindex performance differs between surgically and nonoperatively managed patients when compared with players without an LDH. However, further studies with a larger sample size are required for more definitive recommendations. There is a high RTP rate after LDH in the NBA, although postindex performance may differ based on operative versus nonoperative treatment. © 2015 The Author(s).

    1995-01-01

    The purpose of this study is to describe the patterns of enhancement of the herniated lumbar disc with Gd-DTPA enhanced MR imaging. Out of 65 patients, 103 lumbar discs diagnosed to be herniated by MR image were retrospectively analyzed. The MR imaging was performed with 1.5 T MR unit, using T1-and T2-weighted sagittal and axial spin echo techniques. Contrast-enhanced T1 weighted sagittal and axial images were performed after intravenous injection of Gadopentetate-dimeglumine(Magnevist, Shering) (0.1 mmol/kg). Contrast enhancement was seen in 66 cases(64%). Thirteen cases of bulging disc were not enhanced. Twenty-eight cases of protruded disc showed intraannular enchantment in 23 cases, peripheral linear and irregular enhancement in each of one case, and nonenhancement in three cases. Fifty-seven cases of extruded disc showed irregular enhancement in 14 cases, peripheral linear enhancement in 12 cases, peripheral ring enhancement in five cases and intraannular enhancement in five cases. All five cases of sequestered disc showed peripheral ring enhancement. Protruded discs show intraannular enhancement frequently and sequestered discs usually show peripheral ring enhancement. Enhanced MR imaging may be helpful to evaluate the type of herniated lumbar disc and relationship among disc material, nerve root and thecal sac

  3. Imbalanced Protein Expression Patterns of Anabolic, Catabolic, Anti-Catabolic and Inflammatory Cytokines in Degenerative Cervical Disc Cells: New Indications for Gene Therapeutic Treatments of Cervical Disc Diseases

    2014-01-01

    Degenerative disc disease (DDD) of the cervical spine is common after middle age and can cause loss of disc height with painful nerve impingement, bone and joint inflammation. Despite the clinical importance of these problems, in current publications the pathology of cervical disc degeneration has been studied merely from a morphologic view point using magnetic resonance imaging (MRI), without addressing the issue of biological treatment approaches. So far a wide range of endogenously expressed bioactive factors in degenerative cervical disc cells has not yet been investigated, despite its importance for gene therapeutic approaches. Although degenerative lumbar disc cells have been targeted by different biological treatment approaches, the quantities of disc cells and the concentrations of gene therapeutic factors used in animal models differ extremely. These indicate lack of experimentally acquired data regarding disc cell proliferation and levels of target proteins. Therefore, we analysed proliferation and endogenous expression levels of anabolic, catabolic, ant-catabolic, inflammatory cytokines and matrix proteins of degenerative cervical disc cells in three-dimensional cultures. Preoperative MRI grading of cervical discs was used, then grade III and IV nucleus pulposus (NP) tissues were isolated from 15 patients, operated due to cervical disc herniation. NP cells were cultured for four weeks with low-glucose in collagen I scaffold. Their proliferation rates were analysed using 3-(4, 5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide. Their protein expression levels of 28 therapeutic targets were analysed using enzyme-linked immunosorbent assay. During progressive grades of degeneration NP cell proliferation rates were similar. Significantly decreased aggrecan and collagen II expressions (P<0.0001) were accompanied by accumulations of selective catabolic and inflammatory cytokines (disintegrin and metalloproteinase with thrombospondin motifs 4 and 5, matrix

    Retrospective study. The objective of the study is to evaluate the relationship between the detection rate of lumbar disc herniation and socioeconomic status. Income is one important determinant of public health. Yet, there are no reports about the relationship between socioeconomic status and the detective rate of disc herniation. In this study, 443 cases were checked for lumbar computed tomography for lumbar disc herniation, and they reviewed questionnaires about their socioeconomic status, the presence of back pain or radiating pain and the presence of a medical certificate (to check the medical or surgical treatment for the pain) during the Korean conscription. Without the consideration for the presence of a medical certificate, there was no difference in spinal physical grade according to socioeconomic status (p=0.290). But, with the consideration of the presence of a medical certificate, the significant statistical differences were observed according to socioeconomic status in 249 cases in the presence of a medical certificate (p=0.028). There was a lower detection rate in low economic status individuals than those in the high economic class. The common reason for not submitting a medical certificate is that it is neither necessary for the people of lower socioeconomic status nor is it financially affordable. The prevalence of lumbar disc herniation is not different according to socioeconomic status, but the detective rate was affected by socioeconomic status. Socioeconomic status is an important factor for detecting lumbar disc herniation.

    To evaluate and compare two groups of patients with sciatica due to intervertebral disc herniation with no neurologic deficit. The groups consisted of patients with intervertebral disc herniation in a medial location (group 1) and those in a lateral location (group 2). A total of 200 patients were included in the study and were followed for a minimum of 6 months. In our series, we treated 80 postero-lateral herniated discs (40% of cases), 46 postero-medial herniated discs (23%), and 74 foraminal herniated discs (37%). Level L3-L4 was treated in 30 cases (15%), L4-L5 in 98 cases (49%), and L5-S1 in 72 cases (36%). The procedure was performed under dual guidance: fluoroscopic and CT. A helical probe was activated. It penetrates the herniated disc and causes the pulpous material to be mechanically evacuated through the probe. All 200 patients were followed for a minimum of 6 months. In group 1, the patients had a mean pain score of 7.9 {+-} 2.5 VAS units (range 6-10 units) prior to intervention. This was reduced to 3.2 {+-} 2.1 VAS units (range 0-10 units) at 48 h follow-up and increased to 3.9 {+-} 1.2 VAS units (range 0-10 VAS units) at 1 month follow-up and further reduced to 2.7 {+-} 1.2 units (range 0-10 VAS units) at 6 month follow-up. In group 2, the patients had a mean pain score of 8.2 {+-} 3.2 VAS units (range 6-10 units) prior to intervention. This was reduced to 2.8 {+-} 1.5 VAS units (range 0-10 units) at 48 h follow-up and decreased to 1.5 {+-} 0.9 VAS units (range 0-10 units) at 1 month and further reduced to 1.1 {+-} 0.5 VAS units (range 0-10 units) at 6 months. Our study showed that results were more satisfactory for the hernia located laterally (postero-lateral, foraminal, and extra-foraminal) as compared to the hernia located posteromedially. (orig.)

It penetrates the herniated disc and causes the pulpous material to be mechanically evacuated through the probe. All 200 patients were followed for a minimum of 6 months. In group 1, the patients had a mean pain score of 7.9 ± 2.5 VAS units (range 6-10 units) prior to intervention. This was reduced to 3.2 ± 2.1 VAS units (range 0-10 units) at 48 h follow-up and increased to 3.9 ± 1.2 VAS units (range 0-10 VAS units) at 1 month follow-up and further reduced to 2.7 ± 1.2 units (range 0-10 VAS units) at 6 month follow-up. In group 2, the patients had a mean pain score of 8.2 ± 3.2 VAS units (range 6-10 units) prior to intervention. This was reduced to 2.8 ± 1.5 VAS units (range 0-10 units) at 48 h follow-up and decreased to 1.5 ± 0.9 VAS units (range 0-10 units) at 1 month and further reduced to 1.1 ± 0.5 VAS units (range 0-10 units) at 6 months. Our study showed that results were more satisfactory for the hernia located laterally (postero-lateral, foraminal, and extra-foraminal) as compared to the hernia located posteromedially. (orig.)

    The aim of the investigation was to evaluate the diagnostic effectiveness of sonography in the evaluation of the lower lumbar intervertebral disc herniations. Prospective ultrasonographic examinations by transabdominal approach were performed on 65 consecutive patients (32 males and 33 females) with clinically suspected lumbar disc herniation, and the findings were compared with MR findings. The transabdominal representation of lumbar disc herniations was successful in 64 cases at L3-4 level,59 cases at L4-5 level and 55 cases at L5-S1 level. The sonographic examination wa inconclusive in the some patients because of degenerative disc with vacuum phenomenon, osteophytosis and diminution of the intervertebal disc space. Both sensitivity and specificity of sonography were 100% at L3-4 level. At the same time, the sensitivity and specificity of sonography were 60% and 97% at L4-5 level and 36% and 100% at L5-S1 level. Although ultrasound is not currently used as a screening modality because of the low sensitivity, ultrasound shows a high specificity with non-invasiveness but without radiation hazard. Therefore, ultrasound can be used as an aid for diagnosing lumbar disc herniation, especially in young men without spondylosis.

    To assess multifidus muscle asymmetry using the cross-sectional area (CSA) and perpendicular distance of the multifidus muscle to the lamina (MLD) measurements in patients with nerve compression due to lumbosacral disc hernia. In total, 122 patients who underwent microdiscectomy for unilateral radiculopathy caused by disc herniation, diagnosed by magnetic resonance imaging (MRI), were evaluated retrospectively. Posterolateral or foraminal disc herniation at only one disc level, the L3-4, L4-L5, or L5-S1 region, was confirmed using MRI. Subjects were divided by symptom duration: 1-30 days, (group A), 31-90 days (group B), and > 90 days (group C). There were 48 cases in group A, 26 in group B, and 48 in group C. In groups A, B, and C, the median MLD differed significantly between the diseased and normal sides (P < 0.05). The MLD increased on the diseased side with symptom duration by lumbar disc herniation. The diseased side MLD was 5.1, 6.7, and 7.6 mm in groups A, B, and C, respectively (P < 0.05). The cut-off values for the MLD measurements were 5.3 mm (sensitivity = 62.3 %, specificity = 55.5 %; P < 0.05). In groups A, B, and C, the median CSA of the multifidus muscle was not significantly different between the diseased and the normal side (P > 0.05). The MLD measurement correlated significantly with multifidus asymmetry in patients with lumbar disc herniation. (orig.)

    2014-01-01

    Lumbosacral nerve root anomalies are the leading cause of lumbar surgery failures. Although co-occurrence of lumbar spondylolysis and disc herniation is common, it is very rare to observe that a nerve root anomaly accompanies these lesions. A 49-year-old male patient presented with sudden-onset right leg pain. Examinations revealed L5/S1 lumbar spondylolysis and disc herniation. At preoperative period, he was also diagnosed with lumbosacral root anomaly. Following discectomy and root decompression, stabilization was performed. The complaints of the patient diagnosed with lumbosacral root anomaly at intraoperative period were improved at postoperative period. It should be remembered that in patients with lumbar disc herniation and spondylolysis, lumbar root anomalies may coexist when clinical and neurological picture is severe. Preoperative and perioperative assessments should be made meticulously to prevent neurological injury. PMID:25210343

    Farzad Omidi-Kashani

    2013-12-01

    Full Text Available   Background: Literature recommends that refractory cases with lumbar disc herniation and appropriate indications are better to be treated surgically, but do all the patients throughout the world consent to the surgery with a same disability and pain threshold? We aim to elucidate the prevalence and severity of disabilities and pain in Iranian patients with lumbar disc herniation who have consented to the surgery.   Methods: In this case series study, we clinically evaluated 194 (81 female and 113 male admitted patients with primary, simple, and stable L4-L5 or L5-S1 lumbar disc herniation who were undergoing surgical discectomy. The mean age of the patients was 38.3±11.2 (range: 18-76 years old. Disabilities were evaluated by the items of the Oswestry Disability Index (ODI questionnaire and severity of pain by the Visual Analogue Scale (VAS. Chi-square test was used to compare the qualitative variables. Results: Severe disability (39.2% and crippled (29.9% were the two most common types of disabilities. Mean ODI score was 56.7±21.1 (range: 16-92. Total mean VAS in all patients was 6.1±1.9 (range: 0-10. Sex and level of disc herniation had no statistical effect on preoperative ODI and VAS. The scale of six was the most frequent scale of preoperative VAS in our patients. Conclusion: Iranian patients with lumbar disc herniation who consented to surgery have relatively severe pain or disability. These severities in pain or disabilities have no correlation with sex or level of disc herniation and are not equal with developed countries.

    2010-01-01

    Introduction The purpose of this study was to determine whether ligamentum flavum hypertrophy among disc herniated patients causes contralateral pain symptoms. For this reason we measured the thickness of the ligament in disc herniated patients with ipsilateral or contralateral symptoms. Material and methods Two hundred disc herniated patients with ipsilateral symptoms as group I were compared with five disc herniated patients with only contralateral symptoms as group II. Ligamenta flava thicknesses and spinal canal diameters of both groups were measured on magnetic resonance imaging (MRI) with a micro-caliper. Results Both groups underwent surgery only on the disc herniated side. The total thicknesses of the ligamenta flava in group II was thicker than in group I. There was no spinal stenosis in either group and no significance difference between the groups. Statistically significant differences were found for both ipsilateral and contralateral thickness of the ligament flava in both groups. We also compared thickness of the ligamenta flava for each level of disc herniation in group I; ligamenta flava hypertrophy was more common at L3-L4 and L4-L5 levels of vertebrae in females. Conclusions Aetiology of contralateral sciatica among disc herniated patients may be related to hypertrophy of the ligamenta flava, especially on the opposite side. Surgical approaches of the disc herniated side alone may be sufficient for a good outcome. PMID:22371809

  19. Does nuclear tissue infected with bacteria following disc herniations lead to Modic changes in the adjacent vertebrae?

    Albert, H. B.; Lambert, Peter; Rollason, Jess

    2013-01-01

    PURPOSE: To investigate the prevalence of infected herniated nucleus material in lumbar disc herniations and to determine if patients with an anaerobic infected disc are more likely to develop Modic change (MC) (bone oedema) in the adjacent vertebrae after the disc herniation. MCs (bone oedema...... due to cytokine and propionic acid production. METHODS: Patients undergoing primary surgery at a single spinal level for lumbar disc herniation with an MRI-confirmed lumbar disc herniation, where the annular fibres were penetrated by visible nuclear tissue, had the nucleus material removed. Stringent...... antiseptic sterile protocols were followed. RESULTS: Sixty-one patients were included, mean age 46.4 years (SD 9.7), 27 % female. All patients were immunocompetent.

    The authors studied the histological alterations and the expression of matrix metalloproteinase (MMP)-1 and MMP-3 in disc specimens of patients who had undergone operations for lumbar disc herniation. Forty-three lumbar disc specimens were evaluated histopathologically for degenerative changes and immunohistochemical expression of MMP-1 and MMP-3. The observed degenerative changes provided a degenerative score that was applied in each patient. Sections of disc immunostained for MMP-1 and MMP-3 were evaluated semiquantitatively. Patients were categorized in 3 age groups: 60 years of age. The expression of MMP-1 and MMP-3 were correlated to patient's age, degenerative score, and grade of lumbar disc herniation. There was no statistically significant difference in the degenerative score between the age groups. Degenerative changes were more pronounced in greater grades of herniation (p correlation between MMP-1 and MMP-3 expression and both degenerative score and herniation grade. For the group of patients 30-60 years of age, there was no significant difference between MMP-1 expression and degenerative score, but the correlation between MMP-1 expression and grade of herniation was significant. There was a significant correlation between MMP-3 expression and both degenerative score and herniation grade. Regarding the patients > 60 years of age, there was a significant correlation between MMP-1 and MMP-3 expression and both degenerative score and herniation grade. There was a significantly lower expression of both MMP-1 and MMP-3 in the group correlation was found in MMP-1 and MMP-3 expression between the groups of patients who were 30-60 and > 60 years of age. Interestingly, in age groups > 30 years, there were no statistically significant differences between the expression of MMP-1 and MMP-3, whereas in patients correlated to the age of the patients and the grade of herniation. An important finding in this study is the differential expression of MMP-1 and MMP-3

  1. Lumbar Disc Herniation in a Patient With Congenital Vertebral Body Anomaly: A Case Report

    Atabey, Cem; Topuz, Ali Kivanc; Velioğlu, Murat; Demircan, Mehmet Nusret

    2014-01-01

    Lumbar disc herniation is characterized with low back and leg pain resulting from the degenerated lumbar disc compressing the spinal nerve root. The etiology of degenerative spine is related to age, smoking, microtrauma, obesity, disorders of familial collagen structure, occupational and sports-related physical activity. However, disc herniations induced by congenital lumbar vertebral anomalies are rarely seen. Vertebral fusion defect is one of the causes of congenital anomalies. The pathogenesis of embryological corpus vertebral fusion anomaly is not fully known. In this paper, a 30-year-old patient who had the complaints of low back and right leg pain after falling from a height is presented. She had right L5-S1 disc herniation that had developed on the basis of S1 vertebra corpus fusion anomaly in Lumbar computed tomography. This case has been discussed in the light of literature based on evaluations of Lumbar Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). This case is unique in that it is the first case with development of lumbar disc herniation associated with S1 vertebral corpus fusion anomaly. Congenital malformations with unusual clinical presentation after trauma should be evaluated through advanced radiological imaging techniques. PMID:25620987

  2. Cervical disc arthroplasty: Pros and cons.

    Moatz, Bradley; Tortolani, P Justin

    2012-01-01

    Cervical disc arthroplasty has emerged as a promising potential alternative to anterior cervical discectomy and fusion (ACDF) in appropriately selected patients. Despite a history of excellent outcomes after ACDF, the question as to whether a fusion leads to adjacent segment degeneration remains unanswered. Numerous US investigational device exemption trials comparing cervical arthroplasty to fusion have been conducted to answer this question. This study reviews the current research regarding cervical athroplasty, and emphasizes both the pros and cons of arthroplasty as compared with ACDF. Early clinical outcomes show that cervical arthroplasty is as effective as the standard ACDF. However, this new technology is also associated with an expanding list of novel complications. Although there is no definitive evidence that cervical disc replacement reduces the incidence of adjacent segment degeneration, it does show other advantages; for example, faster return to work, and reduced need for postoperative bracing.

  3. How should we grade lumbar disc herniation and nerve root compression? A systematic review.

    Li, Yiping; Fredrickson, Vance; Resnick, Daniel K

    2015-06-01

    MRI is the gold standard for evaluating the relationship of disc material to soft tissue and neural structures. However, terminologies used to describe lumbar disc herniation and nerve root compression have always been a source of confusion. A clear understanding of lumbar disc terminology among clinicians, radiologists, and researchers is vital for patient care and future research. Through a systematic review of the literature, the purpose of this article is to describe lumbar disc terminology and comment on the reliability of various nomenclature systems and their application to clinical practice. PubMed was used for our literature search using the following MeSH headings: "Magnetic Resonance Imaging and Intervertebral Disc Displacement" and "Lumbar Vertebrae" and terms "nomenclature" or "grading" or "classification". Ten papers evaluating lumbar disc herniation/nerve root compression using different grading criteria and providing information regarding intraobserver and interobserver agreement were identified. To date, the Combined Task Force (CTF) and van Rijn classification systems are the most reliable methods for describing lumbar disc herniation and nerve root compression, respectively. van Rijn dichotomized nerve roots from "definitely no root compression, possibly no root compression, indeterminate root compression, possible root compression, and definite root compression" into no root compression (first three categories) and root compression (last two categories). The CTF classification defines lumbar discs as normal, focal protrusion, broad-based protrusion, or extrusion. The CTF classification system excludes "disc bulges," which is a source of confusion and disagreement among many practitioners. This potentially accounts for its improved reliability compared with other proposed nomenclature systems. The main issue in the management of patients with lumbar disc disease and nerve root compression is correlation of imaging findings with clinical

    2008-01-01

    To evaluate the surgical outcome in terms of functional and subjective recovery, patients who needed discectomies at L1-L2, L2-L3 and L3-L4 levels were compared with an age and sex-matched group of patients who required L4-L5 and L5-S1 discectomies. We prospectively enrolled 50 consecutive patients, referred to our center, who had L1-L2, L2-L3 and L3-L4 herniations and required surgical intervention. Likewise, a comparative group of 50 consecutive patients with herniations at L4-L5 and L5-S1 were selected. All 100 patients were treated and followed for a 1 year period. Physical examination findings as well as Oswestry Disability Questionnaire before surgery were recorded. After 1 year, patients were requested to fill the same questionnaire. Significant decline in the Oswestry Disability Index (ODI) scores was considered to be a measure of functional improvement and recovery. The mean age of patients with upper lumbar disc herniation (L1-L2, L2-L3, L3-L4) was 45.7 years and patients with lower lumbar disc herniation (L4-L5, L5-S1) had a mean age of 41.2 years. There was no statistically significant difference in age between the two groups. The preoperative Oswestry Disability (ODI) Index score had a statistically significant impact on ODI score improvement after surgery in both lower and upper lumbar disc groups. All 100 patients with either lower or upper lumbar disc herniation had statistically significant ODI change after surgical intervention (P disability (ODI of 21-40%) did not show significant improvement, while patients with ODI greater than 40% had significant reduction (P = 0.018). Surprisingly, as many as 25% of the former had even an increase in ODI scores after surgery. Gender was also a conspicuous factor in determining the surgical outcome of patients with upper lumbar disc herniation, and male patients had more reduction in ODI score than female patients (P = 0.007). Since the functional recovery in patients with herniated lumbar disc, especially

  5. Posterior migration of lumbar disc herniation - imaging dilemma due to contrast contraindication: a case report

    Fabrício Guimarães Gonçalves

    2012-06-01

    Full Text Available Disc herniation with posterior epidural migration is a rare and often symptomatic entity. Multiple are the natural barriers that prevent this pattern of migration. Enhanced magnetic resonance imaging is the diagnostic modality of choice in these cases. The diagnostic dilemma in this case was the contraindication to the use of contrast since the patient was known to have chronic renal failure.

  6. Endoscopic Transforaminal Thoracic Foraminotomy and Discectomy for the Treatment of Thoracic Disc Herniation

    Nie, Hong-Fei; Liu, Kai-Xuan

    2013-01-01

    Thoracic disc herniation is a relatively rare yet challenging-to-diagnose condition. Currently there is no universally accepted optimal surgical treatment for symptomatic thoracic disc herniation. Previously reported surgical approaches are often associated with high complication rates. Here we describe our minimally invasive technique of removing thoracic disc herniation, and report the primary results of a series of cases. Between January 2009 and March 2012, 13 patients with symptomatic thoracic disc herniation were treated with endoscopic thoracic foraminotomy and discectomy under local anesthesia. A bone shaver was used to undercut the facet and rib head for foraminotomy. Discectomy was achieved by using grasper, radiofrequency, and the Holmium-YAG laser. We analyzed the clinical outcomes of the patients using the visual analogue scale (VAS), MacNab classification, and Oswestry disability index (ODI). At the final follow up (mean: 17 months; range: 6–41 months), patient self-reported satisfactory rate was 76.9%. The mean VAS for mid back pain was improved from 9.1 to 4.2, and the mean ODI was improved from 61.0 to 43.8. One complication of postoperative spinal headache occurred during the surgery and the patient was successfully treated with epidural blood patch. No other complications were observed or reported during and after the surgery. PMID:24455232

    2014-10-01

    We describe a decade of our experience in the surgical management of patients with giant lumbar intervertebral disc herniation (GILID). This is a case series of patients operated for a GILID between 2000 and 2009. Among 1334 patients eligible for the present study: 154 patients presented with GILID (study group) and 1180 patients without GILID (control group). Clinical symptoms and preoperative imaging results were obtained from medical records. Complications and long-term results were assessed. This retrospective study documents the characteristic features between patients with and without GILID. The difference in the incidence of female patients was statistically significant between the study group and the control group as was the mean duration of symptoms, hyperalgic radicular pain, bilaterality of symptoms, preoperative motor deficit, central location of lumbar disc herniation (LDH), contained herniation and recurrence of LDH. GILIDs are a distinct entity: they are distinctly uncommon compared with smaller herniations, patients were statistically more likely to be hyperalgic with bilateral radicular pain and often associated with neurological deficits. The majority of patients do not display a cauda equina syndrome (CES). Low lumbar disc sites are mostly affected and disc fragments are more likely to be central-uncontained. The recurrence rate is lower for GILIDs. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Background: Low-back pain with leg pain (sciatica) may be caused by a herniated intervertebral disc exerting pressure on the nerve root. Most patients will respond to conservative treatment, but in carefully selected patients, surgical discectomy may provide faster relief of symptoms. Primary care

    1991-01-01

    To understand CT and MR findings and, furthermore, the pathophysiology of the lumbar apophyseal ring fracture (LARF) associated with lumbar disc herniation in 31 cases of LARF (CT was performed in 23, MRI in 18, and both CT and MRI in 12), we studied the age and sex distribution of the patients, history of trauma, shape of bony fragment, number of lesions, lesion sites, associated lumbar disc herniations, and evidence of Scheuermann's disease. Twenty-three out of 31 patients were male, 6 were adolescents, 21 were young adults, and 4 were middled-aged. Arcuate or nodular bone fragment and/or bone defects were detected at the posterior margin of L1 in 2, L2 in 1, L3 in 1, L4 in 10, L5 in 20 and S1 in 7 patients. Eight patients showed multiple LARF, and 13 showed multiple lumbar disc herniations. Radiologic evidence of Scheuermann's disease was obvious in 9 patients. Only 6 patients had a history of evident trauma. CT and MRI showed a similar detection rate of bone fragments and defects. We concluded that LARF would be encountered in young male patients with multiple lumbar disc herniations and evidence of Scheuermann's disease

    To investigate the role of lumbosacral transitional vertebra (LSTV) in the pathogenesis of adolescent lumbar disc herniation (ALDH) and the association between LSTV type and the herniation level of ALDH. This study was a retrospective case-control analysis of roentgenographic images. All adolescent patients who received surgical treatment for L4/5 or L5/S1 single level lumbar disc herniation in our department from 2010 to 2015 were eligible for the ALDH group. All adolescent patients admitted to our hospital during the same period and who had ever undergone a plain anteroposterior radiologic examination of the abdomen and met the inclusion criteria that ensured the absence of any spinal disorders were selected into the control group. The anteroposterior lumbar or abdomen roentgenograms were collected to identify the LSTV. The incidence of LSTV in the ALDH group and the control group were compared. Among the ALDH group, the association between LSTV type (sacralization or lumbarization) and the herniation level of ALDH were evaluated. A total of 80 adolescent patients were included in the ALDH group and 92 asymptomatic adolescents were included in the control group. LSTV was found in 24 patients (30%) in ALDH group compared with 7 patients (7.6%) in the control group (P adolescent patients with sacralization, the L4/5 disc herniation was significantly more common than L5/S1 (81.3% vs. 18.7%; P = 0.019). The LSTV is associated with LDH in adolescents and the sacralization of L5 may contribute to the L4/5 disc herniation in adolescent patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    To evaluate the diagnostic accuracy of multidetector CT (MDCT) for detection of lumbar disc herniation with MRI as standard of reference. Patients with low back pain underwent indicated MDCT (128-row MDCT, helical pitch), 60 patients with iterative reconstruction (IR) and 67 patients with filtered back projection (FBP). Lumbar spine MRI (1.5 T) was performed within 1 month. Signal-to-noise ratios (SNR) of cerebrospinal fluid (CSF), annulus fibrosus (AF) and the spinal cord (SC) were determined for all modalities. Two readers independently rated image quality (IQ), diagnostic confidence and accuracy in the diagnosis of lumbar disc herniation using MRI as standard of reference. Inter-reader correlation was assessed with weighted κ. Sensitivity, specificity, precision and accuracy of MDCT for disc protrusion were 98.8%, 96.5%, 97.1%, 97.8% (disc level), 97.7%, 92.9%, 98.6%, 96.9% (patient level). SNR of IR was significantly higher than FBP. IQ was significantly better in IR owing to visually reduced noise and improved delineation of the discs. κ (>0.90) was excellent for both algorithms. MDCT of the lumbar spine yields high diagnostic accuracy for detection of lumbar disc herniation. IR improves image quality so that the provided diagnostic accuracy is principally equivalent to MRI.

    Full Text Available Abstract Background The overall rate of operations after recurrent lumbar disc herniation has been shown to be 3–11%. However, little is known about the rate of residives. Thus the aim of this study was to explore the cumulative rates of re-operations and especially residive disc herniations at the same side and level as the primary disc herniation after first lumbar disc herniation surgery and the factors that influence the risk of re-operations over a five year follow-up study. Methods 166 virgin lumbar disc herniation patients (mean age 42 years, 57% males were studied. Data on patients' initial disc operations and type and timing of re-operations during the follow-up were collected from patient files. Back and leg pain on visual analog scale and employment status were collected by questionnaires. Results The cumulative rate of re-operations for lumbar disc herniation was 10.2% (95% Cl 6.0 to 15.1. The rate of residives at initial site was 7.4% (95% Cl 3.7 to 11.3 and rate of lumbar disc herniations at other sites was 3.1% (95% Cl 0.6 to 6.2. The occurrence of residive lumbar disc herniations was evenly distributed across the 5 years. Neither age, gender, preoperative symptoms, physical activity nor employment had effect on the probability of re-operation. Conclusion Seven percent of the lumbar disc patients had a residive lumbar disc operation within five years of their first operation. No specific factors influencing the risk for re-operation were found.

    A prospective analysis of computed tomography (CT) and magnetic resonance imaging (MRI) scans in 51 patients with lumbar disc herniation was made to determine the height of hernia for operation and, if impossible, the indications of myelography. Among the 51 patients, 40 (78%) received surgery based on these imaging modalities (Group A); and the remaining 11 (22%) underwent myelography for the confirmation of the height of hernia or detailed examination (Group B). Satisfactory or excellent surgical outcome was achieved in 95% in Group A and in 91% in Group B. Twenty seven patients had multiple disc herniation on CT and MRI; in 17 patients surgery was performed for one disc hernia that was radiologically found to compress the spinal nerve root; and in the other 10 hernia-related disc was not determined by either radiological or neurological manifestations. Satisfactory or excellent surgical outcome could, however, be achieved in 26 patients (96%). Myelography should be indicated when there is no neurological radicular sign in the lower extremities, and when there is no radiological evidence of the compressed spinal nerve root in spite of the presence of multiple disc herniation. The height of hernia may be determined when compression of the spinal nerve root is visualized on CT or MRI. (N.K.).

    To determine the relative frequency of sacroiliac joint dysfunction in a sample of patients with image proven lumbar disc herniation. A single group cross-sectional study was conducted in a three year period from 2007 in an outpatient clinic at a university hospital. Overall, 202 patients aged more than or equal to 18 years with image proven herniated lumbar disc and with physical findings suggestive of lumbosacral root irritation were included. Overall, 146 (72.3%) participants had sacroiliac joint dysfunction. The dysfunction was significantly more prevalent in females (pSacroiliac joint dysfunction is a significant pathogenic factor with high possibility of occurrence in low back pain. Thus, regardless of intervertebral disc pathology, sacroiliac joint dysfunction must be considered in clinical decision making.

  18. Conus medullaris syndrome due to an intradural disc herniation: A case report

    2008-01-01

    Full Text Available A 70-year-old male patient developed acute paraplegia due to conus medullaris compression secondary to extrusion of D12-L1 disc. After negative epidural examination intraoperatively, a durotomy was performed and an intradural disc fragment was excised. Patient did not regain ambulatory status at two-year follow-up. Intraoperative finding of negative extradural compression, tense swollen dura and CSF leak from ventral dura should alert the surgeon for the possibility of intradural disc herniation. A routine preoperative MRI is misleading and a high index of suspicion helps to avoid a missed diagnosis.

    Full Text Available A 70-year-old outpatient presented with a chief complaint of sudden left leg motor weakness and sensory disturbance. He had undergone L4/5 posterior interbody fusion with L3–5 posterior fusions for spondylolisthesis 3 years prior, and the screws were removed 1 year later. He has been followed up for 3 years, and there had been no adjacent segment problems before this presentation. Lumbar magnetic resonance imaging (MRI showed a large L2/3 disc hernia descending to the L3/4 level. Compared to the initial MRI, this hernia occurred in an “intact” disc among multilevel severely degenerated discs. Right leg paresis and bladder dysfunction appeared a few days after admission. Microscopic lumbar disc herniotomy was performed. The right leg motor weakness improved just after the operation, but the moderate left leg motor weakness and difficulty in urination persisted.

  20. Comparison of discectomy versus sequestrectomy in lumbar disc herniation: a meta-analysis of comparative studies.

    Jisheng Ran

    Full Text Available Lumbar disc removal is currently the standard treatment for lumbar disc herniation. No consensus has been achieved whether aggressive disc resection with curettage (discectomy versus conservative removal of the offending disc fragment alone (sequestrectomy provides better outcomes. This study aims to compare the reherniation rate and clinical outcomes between discectomy and sequestrectomy by literature review and a meta-analysis.A systematic search of PubMed, Medline, Embase and the Cochrane Library was performed up to June 1, 2014. Outcomes of interest assessing the two techniques included demographic and clinical baseline characteristics, perioperative variables, complications, recurrent herniation rate and post-operative functional outcomes.Twelve eligible trials evaluating discectomy vs sequestrectomy were identified including one randomized controlled study, five prospective and six retrospective comparative studies. By contrast to discectomy, sequestrectomy was associated with significantly less operative time (p<0.001, lower visual analogue scale (VAS for low back pain (p<0.05, less post-operative analgesic usage (p<0.05 and better patients' satisfaction (p<0.05. Recurrent herniation rate, reoperation rate, intraoperative blood loss, hospitalization duration and VAS for sciatica were without significant difference.According to our pooled data, sequestrectomy entails equivalent reherniation rate and complications compared with discectomy but maintains a lower incidence of recurrent low back pain and higher satisfactory rate. High-quality prospective randomized controlled trials are needed to firmly assess these two procedures.

  1. Ipsilateral atrophy of the psoas major muscle in patients with lumbar disc herniation

    2009-01-01

    We measured the cross-sectional area (CSA) of the psoas major muscles of 48 male patients under 50 years of age with unilateral sciatica caused by a single-level lumbar disc herniation. Patients who had multi-level disc lesions, lumbar canal stenosis, spondylolisthesis, scoliosis>5deg, or a history of lumbar surgery or hip joint disease were excluded. Mean age at surgery was 33 years old. Two orthopedic surgeons measured the CSA independently and blindly on magnetic resonance images in which the spinal canal had been blacked out. The CSA ratio (pain-positive side/pain-negative side) was 0.99 at L3/4, 0.98 at L4/5, and 1.00 at L5/S. There was a statistically significant difference between the CSA of the psoas major muscle on the painful side and the unaffected side at L4/5 (p=0.02). There was no correlation between the CSA ratio and the angle in the straight leg raising test, the duration of symptoms, or the size of the disc herniation. The atrophy of the psoas major muscle observed on the pain-positive side in lumbar disc herniation patients may be attributable to disuse of the affected leg. (author)

  2. Evaluation of epidural blockade as therapy for patients with sciatica secondary to lumbar disc herniation

    2016-08-01

    Full Text Available ABSTRACT OBJECTIVE: Sciatic pain secondary to lumbar disc herniation is a complex condition that is often highly limiting. The causes of pain in disc herniation are multifactorial. Two physiopathological mechanisms are involved in discogenic pain: mechanical deformation of nerve roots and a biochemical inflammatory component resulting from contact between the intervertebral disc and neural tissue, by way of the nucleus pulposus. The aim of this study was to evaluate the efficacy and safety of epidural blockade as therapy for bulging lumbar disc herniation. METHODS: A clinical study was conducted based on a retrospective and prospective survey. The blockade consisted of interlaminar puncture and bolus drug delivery. The number of procedures varied according to the clinical response, as determined through weekly evaluations and then 30, 90, and 180 days after the final session. A total of 124 patients who received one to five blockades were evaluated. RESULTS: The success rate (defining success as a reduction in sciatic pain of at least 80% was 75.8%. CONCLUSION: The results demonstrated the therapeutic action of epidural blockade over the short term, i.e. in cases of acute pain, thus showing that intense and excruciating sciatic pain can be relieved through this technique. Because of the multifactorial genesis of sciatica and the difficulties encountered by healthcare professionals in treating this condition, epidural blockade can become part of therapeutic arsenal available. This procedure is situated between conservative treatment with an eminently clinical focus and surgical approaches.

    We give a description of a technique of the patient's positioning with traction of the arms during the cervical spinal computed tomography which allows to draw the shoulders downwards by about one to three cervical segments. By this method the quality of the images can be improved in 96% in the cervical segment 6/7 and in 81% in the cervical/thoracal segment 7/1 to such a degree that a reliable judgement of the soft parts in the spinal canal becomes possible. The diagnostic reliability of the computed tomography of the cervical disc herniation is thus improved so that the necessity of a myelography is decreasing. The results of 396 cervical spinal computed tomographies are presented. (orig.) [de

    We studied the efficacy of papaine for treatment of herniated discs at a mean 10-year follow-up and compared results with other series and other treatments. From an initial group of 160 patients, 96 patients, 53 men and 43 women, mean age 39 years, were selected for evaluation. These patients had 46 L4L5 herniations and 50 L5S1 herniations. All 96 patients were operated in the same department and received the same dose of papaine under the same anesthesia conditions. All patients were followed regularly to 3 months postoperatively then were reviewed 3 to 17 years after surgery. Inquiries were made about return to work, pain, and activity. Physical examination and x-rays were obtained for all patients. There were no neurological complications in our series. Seventeen patients required a second procedure for sciatic pain. Most of the patients continued their normal occupational and social activities after papaine treatment, but many of them had chronic lumbar pain. Our results were comparable with series reporting a similar long follow-up. Surgery is more efficient than papaine but long-term results are equivalent. Chemopapaine treatment provided good long-term results in our patients, similar to surgery. Chemonucleolysis may be employed as first line treatment for young patients with non-excluded disc herniation with sciatic pain.

  8. A history of lumbar disc herniation from Hippocrates to the 1990s.

    Truumees, Eeric

    2015-06-01

    In ancient times, a supernatural understanding of the syndrome of lumbar radiculopathy often involved demonic forces vexing the individual with often crippling pain. The ancient Greeks and Egyptians began to take a more naturalistic view and, critically, suspected a relationship between lumbar spinal pathology and leg symptoms. Relatively little then changed for those with sciatica until the classic works by Cotugno and Kocher arrived in the late 18th century. Early lumbar canal explorations were performed in the late 1800s and early 1900s by MacEwen, Horsley, Krause, Taylor, Dandy, and Cushing, among others. In these cases, when compressive pathologies were found and removed, the lesions typically were (mis-)identified as enchondromas or osteochondritis dissecans. To better understand the history, learn more about the first treatments of lumbar disc herniation, and evaluate the impact of the early influences on modern spine practice, searches of PubMed and Embase were performed using the search terms discectomy, medical history, lumbar spine surgery, herniated disc, herniated nucleus pulposus, sciatica, and lumbar radiculopathy. Additional sources were identified from the reference lists of the reviewed papers. Many older and ancient sources including De Ischiade Nervosa are available in English translations and were used. When full texts were not available, English abstracts were used. The first true, intentional discectomy surgery was performed by Mixter and Barr in 1932. Early on, a transdural approach was favored. In 1938, Love described the intralaminar, extradural approach. His technique, although modified with improved lighting, magnification, and retractors, remains a staple approach to disc herniations today. Other modalities such as chymopapain have been investigated. Some remain a part of the therapeutic armamentarium, whereas others have disappeared. By the 1970s, CT scanning after myelography markedly improved the clinical evaluation of patients with

    Full Text Available ABSTRACT Objective: To determine the efficacy of anesthetic transforaminal nerve root block in patients with sciatica secondary to lumbar disc herniation through a prospective observational study. Methods: The study included 176 patients from a private clinic undergoing transforaminal injection performed by a single spinal surgeon. The patients were assessed after two weeks, three months and six months regarding to the improvement of the pain radiating to the lower limbs. In case of persistent symptoms, patients could choose to perform a new nerve root block and maintenance of physical therapy or be submitted to conventional microdiscectomy. Results: By the end of six-month follow-up of the 176 patients, 116 had a favorable outcome (95 after one block and 21 after two blocks, and only 43 required surgery. Conclusion: The results of our study suggest a positive effect of transforaminal block for the treatment of sciatica in patients with lumbar disc herniation.

    Current cervical total disc replacement (TDR) designs incorporate a variety of different biomaterials including polyethylene, stainless steel, titanium (Ti), and cobalt-chrome (CoCr). These materials are most important in their utilization as bearing surfaces which allow for articular motion at the disc space. Long-term biological effects of implanted materials include wear debris, host inflammatory immune reactions, and osteolysis resulting in implant failure. We review here the most common materials used in cervical TDR prosthetic devices, examine their bearing surfaces, describe the construction of the seven current cervical TDR devices that are approved for use in the United States, and discuss known adverse biological effects associated with long-term implantation of these materials. It is important to appreciate and understand the variety of biomaterials available in the design and construction of these prosthetics and the considerations which guide their implementation.

  14. Primary immune system responders to nucleus pulposus cells: evidence for immune response in disc herniation

    K Murai

    2010-01-01

    Full Text Available Although intervertebral disc herniation and associated sciatica is a common disease, its molecular pathogenesis is not well understood. Immune responses are thought to be involved. This study provides direct evidence that even non-degenerated nucleus pulposus (NP cells elicit immune responses. An in vitro colony forming inhibition assay demonstrated the suppressive effects of autologous spleen cells on NP cells and an in vitro cytotoxicity assay showed the positive cytotoxic effects of natural killer (NK cells and macrophages on NP cells. Non-degenerated rat NP tissues transplanted into wild type rats and immune-deficient mice demonstrated a significantly higher NP cell survival rate in immune-deficient mice. Immunohistochemical staining showed the presence of macrophages and NK cells in the transplanted NP tissues. These results suggest that even non-degenerated autologous NP cells are recognized by macrophages and NK cells, which may have an immunological function in the early phase of disc herniation. These findings contribute to understanding resorption and the inflammatory reaction to disc herniation.

    Lumbar disc herniation leads to disability by restricting of patients' lives and reducing their quality of life. This situation causes a decrease in motivation of patients by triggering depressive mood. Therefore, the aim of the study was investigation of correlation between fear avoidance beliefs and burnout syndrome in patients with lumbar disc herniation. Totally forty-seven patients (24 male and 23 female patients) diagnosed lumbar disc herniation was included in this study. Maslach II Burnout Inventory (MBI) and Fear Avoidance Beliefs Questionnaire (FABQ) for determining of levels of burnout and fear avoidance level were used, respectively. It was observed that MBI and FABQ scores of the patients were 50.78 ± 10.07 and 36.61 ± 13.91, respectively. Moderate level correlation was found between FABQ and MBI total scores (r= 0.49, p= 0.00). Fear avoidance beliefs of patients with chronic back pain can affect level of burnout syndrome. Therefore, symptoms of burnout syndrome and fear avoidance beliefs of patients should be considered in evaluation and treatment process.

    To observe the clinical effect of post-extension pulling massage in treating lumbar disc herniation. From January 2008 to December 2008, 61 patients with lumbar disc herniation, 34 males and 27 females, ranging in age from 17 to 67 years with an average of 42.6 years, were treated with post-extension pulling massage after continued traction for 30 minutes (on alternate days one time, 3 times as a course of treatment). There was bulging type in 9 cases, hernia type in 22, free type in 30. After a course of treatment, the clinical effects were evaluated according to standard of Macnab, the items included pain, lumbar activity, normal work and life of patients. All patients were followed up from 1 to 9 months with an average of 4.6 months. After treatment, the symptoms and signs of patients had obviously improved in above aspects. According to standard of Macnab, 48 cases got excellent result, 10 good, 2 fair, 1 poor. The post-extension pulling massage in treating lumbar disc herniation can obtain satisfactory results, which have localized site of action, small compression for vertebral body and can reduce accidental injury.

  17. The Relationship between Lifestyle and Pain in Patients with Spinal Disc Herniation

    Full Text Available Due to the rapid growth of the industries and constantly involvement of the new technologies into the human lives, the lifestyles of the people are altering. Simultaneously few new disorders in their lifestyles and diseases in their lives are also emerging. The spinal cord abnormalities i.e., the spinal disc herniation and/or low back pain is one of them which have made the life of some people very miserable (Farahani et al., 2012. Indeed the overall lifestyle of a human being regulates the musculoskeletal symptoms. Differences in lifestyle and psychosocial factors associated with individuals' lifestyle are effective in experiencing the level of pressure in musculoskeletal systems. Studies related to the lifestyle and musculoskeletal system, including pain and inflammation, are largely correlate (Mikkonen et al., 2015. Proper knowledge regarding the relationship between lifestyle and spinal disc herniation is very important. Social habits such as diet, exercise, weight gain, anxiety, and depression can cause changes in the spinal cord and spinal disc herniation (Kadow et al., 2014. Further, some of the lifestyle parameters such as smoking, nutrition, BMI, level of activity, sleep status, stress, and anxiety are also seen to reduce the need for medication or avoid and reduce musculoskeletal pain (Dean et al., 2015. As per Bohman et al. (2014 people with a healthy lifestyle suffer 66% less from low back pain than those who have unhealthy lifestyles.

These cushions, called disks, separate the spinal vertebrae/bones. When one of the disks herniates (moves out of place) in patients with protruded disc, the soft gel inside pushes through the wall of the disk. The disk may then place pressure on the spinal cord and nerves that are coming out of the spinal column. The lumbar discectomy procedure remained basically ...

    We collected the samples of cervical intervertebral discs from patients with vertigo to examine the distribution and types of mechanoreceptors in diseased cervical disc. The aim of this study was to determine whether mechanoreceptors are distributed more abundantly in cervical discs from patients with cervical spondylosis, and whether they are related to vertigo. Previous limited studies have found that normal cervical intervertebral discs are supplied with mechanoreceptors that have been considered responsible for proprioceptive functions. Several clinical studies have indicated that the patients with cervical spondylosis manifested significantly impaired postural control and subjective balance disturbance. We collected 77 samples of cervical discs from 62 cervical spondylosis patients without vertigo, 61 samples from 54 patients with vertigo, and 40 control samples from 8 cadaveric donors to investigate distribution of mechanoreceptors containing neurofilament (NF200) and S-100 protein immunoreactive nerve endings. The immunohistochemical investigation revealed that the most frequently encountered mechanoreceptors were the Ruffini corpuscles in all groups of cervical disc samples. They were obviously increased in the number and deeply ingrown into inner annulus fibrosus and even into nucleus pulposus in the diseased cervical discs from patients with vertigo in comparison with the discs from patients without vertigo and control discs. Only three Golgi endings were seen in the three samples from patients with vertigo. No Pacinian corpuscles were found in any samples of cervical discs. The diseased cervical discs from patients with vertigo had more abundant distribution of Ruffini corpuscles than other discs. A positive association between the increased number and ingrowth of Ruffini corpuscles in the diseased cervical disc and the incidence of vertigo in the patients with cervical spondylosis was found, which may indicate a key role of Ruffini corpuscles in the

    Eight patients, who had symptoms and signs of cervical spondylosis and/or disk were studied with myelography (using Omnipaque) followed by postmyelographic computed tomography to evaluate the relative efficacy of these two methods in the determination of cervical herniation and spondylosis. Thirty nine levels in 26 patients were confirmed by surgery. Of these, 20 levels proved to have operative evidence of herniated disk. Postmyelographic CT adds useful information to the myelographic findings. Cord and root compression are better evaluated and osteopathy can be differentiated from disk herniation. In osteopathy, myelography was as diagnostic as postmyelographic CT. But, disk herniation was identified in 70% (14/20 levels) with postmyelographic CT and only in 15% (3/20 levels) with myelography.

    2007-01-01

    Objective: To compare the outcomes of percutaneous laser disc decompression (PLDD) and PLDD with synchronous suction through syringe in the patients with herniated lumbar disc (HLD). Methods: Forty-two patients with HLD on MRI and those who did not respond to conservative treatment for 6 weeks were randomly divided into group A and group B. In group A, the patients were treated with PLDD and those in group B with PLDD and synchronous suction through syringe. GaAIAS diode laser at 810 nm was used for the ablation in both groups. The treatment effect was evaluated by modified MacNab's criteria on the 7th, 30th and 90th day. Results: Evaluated by modified MacNab's criteria, the percentages of the excellent and good cases in total patients treated for group B and A were 80.95% and 57.14% on the 7th follow-up day, 85.71% and 66.67% on the 30th follow-up day, and 95.24% and 71.43% on the 90th follow-up day, respectively. Conclusion: Synchronous suction technique through syringe during PLDD improves the overall outcome in the treatment of herniated lumbar disc.

  5. Evaluation of Lumbosacral Angle (LSA and its Impact on Patients with Lumbar Disc Herniation

    2016-04-01

    Full Text Available Aim: One of the most common causes of low back pain is lumbar disc herniation (LDH. One of the treatments for patients with LDH is a surgical operation. Changes in the lumbar lordosis angle have a negative impact on patients, clinically. The significance of changes in the lordosis-sacral inclination angle that are associated with muscle spasms and are seen after LDH surgery is known. In this study, we would like to examine the clinical impact on patients due to changes in the lumbosacral angle measured before and after surgical operations in patients with LDH. Material and Method: Between 2005%u20132007, preoperative and postoperative lumbosacral angles of 139 patients operated on for a diagnosis of lumbar disc herniation were measured. Patients were evaluated with the Oswestry Scale, Visual Analogue Scale, Narcotic Score, and Patient Satisfaction Evaluation. Lumbar lordosis angle, sacral inclination angle, and disc height were calculated by direct radiography. Statistical analysis was performed with GraphPad Prisma V.3 software package. Results: In this study, increases of lordosis angles and sacral inclination angles have been observed, postoperatively. It has been shown that these have a positive impact on the clinical course. Discussion: The clinical effects of the biomechanics of angles of patients with LDH are clear. Biomechanical parameters should be considered at preoperative treatment, postoperative treatment, and postoperative controls. The patient%u2019s lordosis angle, neighboring disc structure, and relationship with the sacrum must be carefully evaluated for surgical decision.

    Degenerative processes in a movement segment of the vertebral column, which can potentially give rise to herniation of elements of the nucleus pulposus, are complex and of variable clinical and radiological dimensions; however the mere assumption that degenerative changes precede disc herniation remains a matter of debate. By definition, spinal disc herniation (SDH) refers to components of the gelatinous nucleus pulposus protruding beyond the dorsal level of the vertebral body margin through tears in the annulus fibrosus. Clinical presentation may include pain, paresis and sensory disturbances. Magnetic resonance imaging (MRI) is considered the gold standard in the diagnosis of SDH. In the majority of patients a conservative approach with physical therapy exercises and adequate analgesic and antiphlogistic medical treatment results in a substantial improvement of symptoms. (orig.) [German] Degenerative Prozesse eines Bewegungssegments, die in einem Prolaps des Nucleus pulposus resultieren koennen, sind vielschichtig und von unterschiedlicher klinischer und radiologischer Auspraegung. Selbst die Annahme, dass Bandscheibenvorfaellen eine Degeneration vorangeht, ist keineswegs unumstritten. Definitionsgemaess spricht man von einem Bandscheibenvorfall (BSV), wenn das Gewebe des gelatinoesen Nucleus pulposus durch eine Dehiszenz im Anulus fibrosus ueber das Niveau der normalen dorsalen Begrenzung des Bandscheibenfachs hinaus prolabiert. Klinisch kann dies mit Schmerzen, Paresen und Sensibilitaetsstoerungen einhergehen. Die Magnetresonanztomographie gilt als Goldstandard in der Diagnostik eines BSV. In der Mehrzahl der Faelle fuehrt ein konservatives Vorgehen zu einer deutlichen Besserung der Symptomatik im Verlauf. (orig.)

    Objective: To evaluate the efficacy of endoscopic discectomy for the lumbar disc herniation and to determine the prognostic factors affecting surgical outcome. Methods: In the group of 160 cases, posterolateral and trans-interlaminar endoscopic Ho: YAG laser and radio frequency-assisted disc excisions were performed under local anesthesia. Results: In 160 patients with post-surgical follow-up period was 15 months on average (7 ∼ 24 months). Based on the MacNab criteria, there were 117 cases in which result was excellent, in 19 cases good, in 12 cases fair, and in 12 cases poor, and successful rate was 85%. Conclusion: Percutaneous endoscopy lumbar discectomy is effective for recurrent disc herniation in the selected. In applies in particular to the traditional open surgery of lumbar disc herniation in patients with recurrent. (authors)

    1985-07-01

    Twenty patients suffering from the cervical disc disorders were examined by CT scan after cervical discography. Cervical discs are situated in horizontal plane and contrast medium spreads in horizontal course. The horizontal analysis obtained by CT discography supplies several new findings useful to diagnosis and surgical treatment. Especially it can correct the false negative or the false positive findings of other radiological examinations.

  10. Diffusion-weighted imaging and diffusion tensor imaging of asymptomatic lumbar disc herniation.

    Sakai, Toshinori; Miyagi, Ryo; Yamabe, Eiko; Fujinaga, Yasunari; N Bhatia, Nitin; Yoshioka, Hiroshi

    2014-01-01

    Diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) were performed on a healthy 31-year-old man with asymptomatic lumbar disc herniation. Although the left S1 nerve root was obviously entrapped by a herniated mass, neither DWI nor DTI showed any significant findings for the nerve root. Decreased apparent diffusion coefficient (ADC) values and increased fractional anisotropy (FA) values were found. These results are contrary to those in previously published studies of symptomatic patients, in which a combination of increased ADC and decreased FA seem to have a relationship with nerve injury and subsequent symptoms, such as leg pain or palsy. Our results seen in an asymptomatic subject suggest that the compressed nerve with no injury, such as edema, demyelination, or persistent axonal injury, may be indicated by a combination of decreased ADC and increased FA. ADC and FA could therefore be potential tools to elucidate the pathomechanism of radiculopathy.

    Shoulder problems are common in patients with a cervical herniated intervertebral disc (HIVD). This study aimed to explore the incidence and risk of shoulder capsulitis/tendonitis following cervical HIVD surgery. We used data from the Taiwan "Longitudinal Health Insurance Database". We identified all patients who were hospitalized with a diagnosis of displacement of a cervical HIVD and who underwent cervical surgery (n = 1625). We selected 8125 patients who received cervical HIVD conservative therapy only as the comparison group matched with study patients. We individually tracked these sampled patients for 6 months to identify all patients who received a diagnosis of shoulder tendonitis/capsulitis. We found that incidence rates of shoulder tendonitis/capsulitis during the 6-month follow-up period were 3.69 (95% CI: 2.49~5.27) per 100 person-years for the study group and 2.33 (95% CI: 1.89~2.86) per 100 person-years for the comparison group. Cox proportional hazard regressions showed that the adjusted hazard ratio for shoulder tendonitis/capsulitis among patients who underwent cervical disc surgery was 1.66 (95% CI = 1.09~2.53) when compared to comparison group. We concluded that patients who underwent surgery for a cervical HIVD had a significantly higher risk of developing shoulder capsulitis/tendonitis in 6 months follow-up compared to patients who received cervical HIVD conservative therapy only.

    2003-01-01

    Objective: To evaluate the therapeutic effect and safety for the treatment of lumbar disc herniation by using intradiscal and paraspinal space injection of O 2 -O 3 mixture. Methods: One hundred and twenty-nine patients were selected in this study. All patients presented the symptoms of sciatica and low back pain. The diagnosis of the lumbar disc herniation including 47 bulging, 78 protrusion, and 4 extrusion was verified by CT or MR imaging. One hundred and eighty-nine herniated discs were chosen as therapeutic targets. O 2 -O 3 mixture at 40 μg/ml and 19-21G puncture needles were prepared. The injection was conducted through the puncture of intradiscal and paraspinal space. For each herniated disc treatment, 5 ml O 2 -O 3 mixture were injected into the intradiscal space and 10-15 ml into paraspinal space. Results: The patients were followed up from 3 to 18 months after treatment. The therapeutic effect showed that 79 patients (61.2%) had excellent recovery, 19 cases (14.7%) had significant relief of symptoms, and 31 patients (24.0%) got failure in treatment. No serious complication occurred. Conclusion: The therapeutic method of O 2 -O 3 mixture injection into the lumbar intradiscal and paraspinal space was a safe and effective method for the treatment of the lumbar disc herniation

    1994-01-01

    To describe normal postoperative MR findings and MR findings of postoperative discitis in patients who underwent operation due to herniated intervertebral disc. We retrospectively reviewed normal postoperative MR findings and MR findings of discitis in 30 patients(21-61 yrs) (13 cases diagnosed as discitis and 17 cases as normal) who previously underwent laminectomy and discectomy, or bony fusion. We analyzed signal intensity of end plate and disc, end plate destruction,and enhancement of end plate and disc on T1- and T2-weighted images(WI) of 1.5 T MRI. Among 14 out 17 patients with no evidence of discitis, 7 patients showed high signal of the posterior portion of disc on T1- and T2-WI and 11 patients revealed enhancement at the same sites. In all 13 patients suspected of having discitis, end plate and disc showed low signal on T1-WI, high signal on T2-WI, heterogeneous enhancement,and irregular destruction of end plate. Meanwhile, 3 cases with no evidence of postoperative discitis clinically who underwent bony fusion showed similar findings to those of the above 13 patients, except for homogeneous enhancement of end plate and vertebral body. The MR findings of postoperative discitis were low signal on T1-WI, high signal on T2-WI, and heterogeneous enhancement of and plate and disc, and destruction of end plate

  14. Prevalence of Concomitant Sacroiliac joint Dysfunction in Patients With Image Proven Herniated Lumbar Discs

    Salah Alalawi

    2009-05-01

    Full Text Available Background:Sacroiliac joint (SIJ dysfunction is a widely known but poorly defined cause of low back pain. To our knowledge, few published studies have been conducted to evaluate systematically the prevalence and significance of concomitant sacroiliac joint dysfunction in patients with herniated lumbar discs. As concomitant SIJ dysfunction in low back pain patients is likely to respond to particular noninvasive interventions such as manipulation,improved understanding of the relationship between these two diagnoses would improve clinical decision making and research.Methods:This study was designated to estimate the prevalence of concomitant sacroiliac joint dysfunction in sub acute low back pain patients with image proven discopathy and evaluate the theory that sacroiliac joint dysfunction can be a source of pain and functional disability in discopathy. A total of 202 patients with sub acute radicular back pain and MRI proven herniated lumbar discs underwent standardized   physiatrist history and physical examination, specified for detection of concomitant sacroiliac joint dysfunction.Results: Sacroiliac joint dysfunction is a concomitant finding in 72.3% of evaluated patients.There was significantly higher SIJ dysfunction prevalence in female patients (p <0.0001. Conclusion: SIJ dysfunction is a significant pathogenic factor with high possibility of occurrence in low back pain. Thus, in the presence of radicular and sacroiliac joint symptoms, SIJ dysfunction, regardless of intervertebral disc pathology, must be considered in clinical decisiomaking.

    2004-01-01

    Objective: To evaluate the effect of the percutaneous lumbar puncture to treat sciatica caused by lumbar disc herniation. Methods: 75 cases of lumbar disc herniation with significant clinical signs were confirmed by CT scan. The technique of the percutaneous lumbar puncture led the needle to approach nerve root and injected medicine diffusing into extraduramater, and then relieved the symptom of sciatica. Results: The rate of success of percutaneous lumbar puncture guided by CT reached to 100%. After two weeks of follow-up, the symptom of pain was obviously improved and disappeared in 63.3% cases. There were 23.0% cases needed a second procedure, and no change was obsesved in 9.3% cases. Conclusions: The percutaneous lumbar puncture guided by CT to treat sciatica resulted from lumbar disc herniation is one of the safe, reliable, effective new methods with no complication. The long term effectiveness is still in need of investigation. (authors)

    1996-01-01

    To evaluate the relationship between the direction of herniated disc and pressure effect on nerve root and dural sac, as seen on MRI. We retrospectively reviewed lumbar spine MR images of 122 cases of lumbar disk herniation 75 patients MRI findings were analyzed with regard to the relationship between the direction of the herniated disc and pressure effect on nerve root and dural sac. Pressure effect on nerve root and dural sac was arbitrarily divided into three types. Type I was defined as zero or minimal compression of nerve roots or thecal sac by the herniated disc ; type II was defined as mild to moderate compression, while III was defined as severe compression or displacement of nerve roots and/or thecal sac. Of the 122 cases seen in these 75 patients, 97(80%) were observed at L4-5 and L5-S1. The central type(71cases ; 58%) was more frequently observed than the posterolateral type(48cases ; 40%) or lateral type(3cases ; 2%). The totals of types I, II, and III were 44(36%), 43(35%) and 35 cases(29%), respectively. Seventy-seven %(34/44) of type I and 65%(28/43) of type II were of the central type but for type III, the corresponding figure was only 26%(9/35). On MR imaging, most of lumbar disk herniations were observed at L4-5 and L5-S1, with a predominance of the central type rather than the posterolateral one. Most of the central types were either type I or type II

  19. Comparison of radiation delivered by current diagnostic procedures for herniated disc

    Gasquet, C.; Drouineau, J.; Goubault, F.; Hurmic, A.; Lavigne, B.; Vandermarcq, P.

    1983-01-01

    Three methods are currently employed for the diagnosis of sciatica due to disc lesions: radiculography, spinal phlebography, and computed tomography. Though their indications vary according to the author, it seemed worthwhile to compare radiation delivered by each of them, because of the often young age of the patients. Dosimetric studies using a Rando Phantom enabled calculation of doses to the skin, spinal cord, and gonads. Results indicated that low doses were delivered by the scanner, relatively high doses by spinal phlebography, and intermediate doses by radiculography. These findings suggest that the initial examination preoperatively in cases of simple sciatica due to herniated disc should be a CT scan whenever possible. Phlebography, on the contrary, and particularly in young women, should be used only exceptionally, as a result of the high doses delivered to the ovaries even during technically simple explorations [fr

  20. Changes of signal intensity on precontrast magnetic resonance imaging in spontaneously regressed lumbar disc herniation

    Okushima, Yuichiro; Chiba, Kazuhiro; Matsumoto, Morio; Maruiwa, Hirofumi; Nishizawa, Takashi; Toyama, Yoshiaki

    2001-01-01

    To see whether the MRI images can give a criterion for conservative therapy of the lumbar disc herniation, time changes of the images were retrospectively studied on 41 cases of spontaneous regression. They had the imaging diagnosis 3 times in average until regression with GE Signa equipment (1.5T). Images were evaluated by 2 experts. Certain cases accompanying the brightness change were seen during the process of regression. The period leading to the disappearance of melosalgia and to the regression tended to be short in cases with the brighter pulp center than disc and/or with less bright pulp verge than center. Further studies were thought necessary for clear conclusion. (K.H.)

    Kaveh Haddadi

    2016-01-01

    Full Text Available Lumbar disc herniation (LDH is a public complaint among adults with degenerated lumbar intervertebral discs. However, its incidence in childhood and adolescence is abundant. This dissimilarity designates that children are distant from being just little adults. Findings recommended that pediatric LDH is, in numerous ways, dissimilar from that in adults. The occurrence, the etiological and the diagnostic topographies of pediatric LDH have been entirely described in the text, while the features concerning the treatment have not been yet studied in details. It was confirmed that pediatric patients respond to conventional management less positively as matched with adults. Also, the consequences of the operation continued to be acceptable for at least 10 years after the first surgery, even though it seems to decline somewhat. The purpose of the current review is to offer a comparative view on the management of pediatric LDH.

  2. A clinical study on diagnostic value of CT-myelography in herniated lumbar disc and related disorders

    Endo, Tohru

    1984-01-01

    In order to evaluate the diagnostic value of CT-myelography (CTM) in herniated lumbar disc and related disorders, myelography and CTM were performed on 60 patients with sciatic pain and the findings obtained were compared. Among these patients, operation was undertaken in 30 including 5 reoperated patients, and preoperative findings on CTM were compared with the grades of herniated disc observed at operation. On the basis of abnormal myelographic findings of 55 patients, excluding 5 reoperated patients, morphological changes of the CTM were classified into the following seven types; normal, anterior defect, lateral defect, antero-lateral defect, root defect or thinning, total defect, and anterior plus unilateral root defect or thinning. Agreetment between myelographic and CTM findings was found in 85.1% of the cases. While myelography permitted only an indefinite diagnosis of lumbar disc lesion, CTM permitted a define diagnosis in 8 intervertebral discs including 2 giving nomal results by CTM. In cases of reoperation, CTM provided usefull information for an analysis of the pathological changes included disc herniation, whereas myelography rarely provided usefull findings. A comparative study of CTM and surgical findings revealed that the morphological changes in CTM were closely related with the grades of herniated discs. Consequently, CTM may be performed after myelography. If findings by the two techniques are synthesized, the diagnostic rate of herniated lumbar disc and related disorders will be considerably improved. Furthermore, it is concluded that CTM is an important technique for observing bony and neural changes inside the spinal canal in the axial transverse plane. (author)

  3. Grading system for migrated lumbar disc herniation on sagittal magnetic resonance imaging. An agreement study

    Ahn, Y.; Jeong, T.S. [Gachon University Gil Medical Center, Department of Neurosurgery, Incheon (Korea, Republic of); Lim, T.; Jeon, J.Y. [Gachon University Gil Medical Center, Department of Radiology, Incheon (Korea, Republic of)

    2018-01-15

    Migrated lumbar disc herniations (LDHs) in the sagittal plane are common. Disc migration grading can be applied as a useful measurement tool in the diagnosis, treatment, and outcome evaluation of migrated LDH. No study has evaluated the reliability of migrated LDH grading. We evaluated the reliability and functionality of the current magnetic resonance imaging (MRI) grading system for migrated LDH. We assessed a six-level grading system developed based on sagittal MRI and graded according to the direction (rostral and caudal) and degree (low, high, and very high) of disc migration. One-hundred and one migrated LDHs treated with minimally invasive endoscopic discectomy were analyzed independently by two experienced radiologists. Intraobserver and interobserver agreements were assessed by kappa statistics. The most common migrated LDH grade was grade 4 (30.94%; caudal, low-grade migration). Rostral and caudal migrations were more common in the upper and lower lumbar levels, respectively. Interobserver agreement in the grading of migrated LDH was good at both the first (kappa = 0.737) and second assessment (kappa = 0.657). The intraobserver agreement for reader 1 was very good (kappa = 0.827) and for reader 2 was good (kappa = 0.620). The current grading system for migrated LDH was found to be reliable and functional with good interobserver and intraobserver agreement. It may be useful in the interpretation of disc migration patterns and outcomes of various minimally invasive surgical procedures. (orig.)

    2017-01-01

    Abstract Background: Around 90% of sciatica cases are due to a herniated intervertebral disc in the lumbar region. Ankle acupuncture (AA) has been reported to be effective in the treatment of acute nonspecific low back pain. This study aims to evaluate the efficacy of a single session of ankle acupuncture for disc-related sciatica. Method: This will be a double-blinded, randomized controlled clinical trial. Patients diagnosed with disc-related sciatica will be randomly divided into 3 parallel groups. The treatment group (n = 30) will receive ankle acupuncture. The 2 control groups will either undergo traditional needle manipulation (n = 30) or sham acupuncture (n = 30) at the same point as the treatment group. The primary outcome will be pain intensity on a visual analog scale (VAS). The secondary outcomes will be paresthesia intensity on a VAS and the Abbreviated Acceptability Rating Profile (AAPR). The success of blinding will be evaluated, and the needle-induced sensation and adverse events will be recorded. All outcomes will be evaluated before, during, and after the treatment. Discussion: This study will determine the immediate effect and specificity of ankle acupuncture for the treatment of disc-related sciatica. We anticipate that ankle acupuncture might be more effective than traditional needle manipulation or sham acupuncture.

    Full Text Available Context: Little seems to be known about the sexual dysfunction (SD in lumbar intervertebral disc herniation. Aims: Investigation of sexual and sphincter dysfunction in patient with lumbar disc hernitions. Settings and Design: A retrospective analysis. Materials and Methods: Sexual and sphincter dysfunction in patients admitted with lumbar disc herniations between September 2012-March 2014. Statistical Analysis Used: Statistical analysis was performed using the Predictive Analytics SoftWare (PASW Statistics 18.0 for Windows (Statistical Package for the Social Sciences, SPSS Inc., Chicago, Illinois. The statistical significance was set at P < 0.05. The Wilcoxon signed ranks test was used to evaluate the difference between patients. Results: Four patients with sexual and sphincter dysfunction were found, including two women and two men, aged between 20 and 52 years. All of them admitted without low back pain. In addition, on neurological examination, reflex and motor deficit were not found. However, almost all patients had perianal sensory deficit and sexual and sphincter dysfunction. Magnetic resonance imaging (MRI of three patients displayed a large extruded disc fragment at L5-S1 level on the left side. In fourth patient, there were not prominent disc herniations. There was not statistically significant difference between pre-operative and post-operative sexual function, anal-urethral sphincter function, and perianal sensation score. A syndrome in L5-S1 disc herniation with sexual and sphincter dysfunction without pain and muscle weakness was noted. We think that it is crucial for neurosurgeons to early realise that paralysis of the sphincter and sexual dysfunction are possible in patients with lumbar L5-S1 disc disease. Conclusion: A syndrome with perianal sensory deficit, paralysis of the sphincter, and sexual dysfunction may occur in patients with lumbar L5-S1 disc disease. The improvement of perianal sensory deficit after surgery was

    Prospective cohort study. To report the clinical course of patients with MRI-confirmed lumbar disc herniation-related radicular noncentralizing pain who received transforaminal epidural steroid injections (TESIs) and mechanical diagnosis and therapy (MDT). Noncentralizing symptoms in patients with lumbar disc herniation are associated with poor outcome. Commonly used treatments for these patients include TESIs and MDT. No study has evaluated the outcome of combining both strategies. Consecutive candidates for herniated lumbar disc surgery with noncentralizing chronic pain were eligible. Patients received TESIs followed by MDT. The primary outcomes were pain severity in the leg, disability (Roland-Morris Disability Questionnaire for Sciatica), and global perceived effect (GPE). Outcomes were measured at baseline, discharge, and 12 months. Linear mixed-models and McNemar's tests were used to analyze outcome data. Sixty-nine patients receive TESIs. After TESIs, symptoms were resolved completely in 11 patients (16%). In these patients, symptom resolution was maintained at 12 months. A second subgroup of 32 patients (46%) reported significantly less pain after TESIs and showed centralization with MDT reassessment (significant reductions in leg pain and disability [P TESIs but still showed noncentralization with MDT reassessment (significant reductions in leg pain and disability [P TESIs and received an operative intervention. The results indicate that a course of TESIs followed by MDT may be able to avoid surgery in a substantial proportion of candidates for herniated lumbar disc surgery. Wiley Periodicals, Inc.

  7. Imaging of Spinal Cord Injury: Acute Cervical Spinal Cord Injury, Cervical Spondylotic Myelopathy, and Cord Herniation.

    2016-10-01

    We review the pathophysiology and imaging findings of acute traumatic spinal cord injury (SCI), cervical spondylotic myelopathy, and briefly review the much less common cord herniation as a unique cause of myelopathy. Acute traumatic SCI is devastating to the patient and the costs to society are staggering. There are currently no "cures" for SCI and the only accepted pharmacologic treatment regimen for traumatic SCI is currently being questioned. Evaluation and prognostication of SCI is a demanding area with significant deficiencies, including lack of biomarkers. Accurate classification of SCI is heavily dependent on a good clinical examination, the results of which can vary substantially based upon the patient׳s condition or comorbidities and the skills of the examiner. Moreover, the full extent of a patients׳ neurologic injury may not become apparent for days after injury; by then, therapeutic response may be limited. Although magnetic resonance imaging (MRI) is the best imaging modality for the evaluation of spinal cord parenchyma, conventional MR techniques do not appear to differentiate edema from axonal injury. Recently, it is proposed that in addition to characterizing the anatomic extent of injury, metrics derived from conventional MRI and diffusion tensor imaging, in conjunction with the neurological examination, can serve as a reliable objective biomarker for determination of the extent of neurologic injury and early identification of patients who would benefit from treatment. Cervical spondylosis is a common disorder affecting predominantly the elderly with a potential to narrow the spinal canal and thereby impinge or compress upon the neural elements leading to cervical spondylotic myelopathy and radiculopathy. It is the commonest nontraumatic cause of spinal cord disorder in adults. Imaging plays an important role in grading the severity of spondylosis and detecting cord abnormalities suggesting myelopathy. Copyright © 2016 Elsevier Inc. All rights

    Full Text Available Cauda equina syndrome (CES is a rare neurologic condition that is caused by compression of the cauda equina. Cauda equina consists of spinal nerves L2-L5, S1-S5 and the coccygeal nerve. The compression of these nerve roots can be caused mainly by lumbar disc herniation (45% of all causes. The diagnosis consists of two critical points: a detailed history and physical examination and b MRI or CT. The gold standard of the treatment of this syndrome is the surgical approach in combination with the timing of onset of symptoms. The surgery as an emergency situation is recommended in the fi rst 48 hours of onset of symptoms. Any delay in diagnosis and treatment leads to a poor prognosis of CES.

    Gregebo, Birgitta; Dai, Deliang; Schillberg, Birgitta; Baehr, Martin; Nyström, Bo; Taube, Adam

    2014-01-01

    In the 2006 yearly report from the Swedish National Register for Lumbar Spine Surgery it was claimed that international studies show obvious differences between private and non-private patients with regard to results from back surgery. Therefore our aim was to reveal such possible differences by comparing the two categories of patients at a private clinic. The material comprises 1184 patients operated on for lumbar disc herniation during the period of 1987 to 2007. Basic pre-operative data were obtained from the medical records and follow-up was performed by a questionnaire around 5 years post-operatively. Small but statistically significant differences between private and non-private patients were seen pre-operatively regarding the proportions of a/ men and women in the samples, b/ those with physically demanding jobs, c/ those on sick leave and d/ those with lumbar pain. Over the years the admitted private patients had a decreasing mean duration of symptoms which was not seen in the non-private patients. No apparent differences (n.s.) were seen between the two categories of patients pre-operatively regarding age, presence and level of leg pain or the proportion who smoked. Post-operative improvement in leg and lumbar pain was very similar in private and non-private patients as was satisfaction with the results and the proportion of patients returning to work. Despite small pre-operative differences concerning some variables and a significant difference in symptom duration between private and non-private disc herniation patients, the final clinical results were very similar.

A pesar de que el número limitado de pacientes no permite conclusiones estadísticas significativas, factores anatómicos intrínsecos del paciente como cuello corto y diámetro aumentado, bien como tiempo quirúrgico y dificultades técnicas que puedan aumentarlo, pueden estar asociados a lesiones en el NLR. Nuevos estudios evaluando las variables arriba estudiadas deben ser considerados.OBJECTIVE: To study other possible factors associated with RLN injury after anterior approach for treatment of disc herniation. METHODS: Between June 2009 and July 2010, we evaluated 30 patients underwent anterior approach for treatment of disc herniation in Hospital Sao Lucas, PUC-RS. At preoperative period, we evaluated the measure of neck circumference (at the level of the cricoid cartilage and cervical height (angle of the jaw to the upper edge of the clavicle. At perioperative period, we evaluated the time and difficulty in endotracheal intubation, surgical time, the approach side , the number of levels operated, and the type of incision (transverse / longitudinal and the use of the cranial halo. An endoscopic evaluation of the larynx was performed preoperatively. In the first 10 days after surgery, it was performed a second evaluation. The patients who had a normal second examination were considered without RLN injury. Patients who showed injuries were followed monthly until a period of six months when injuries were considered as definitive. RESULTS: We found 3/30 (10% cases of temporary RLN injury which recovered to up to 120 days post operate. Related to patients with no RLN injury, these patients had a neck circumference greater than average, their surgical time was above average, as well the number of levels operated, and the neck length was shorter than average. Two injuries occurred in the approach through the right side and one in the left side. All

    Full Text Available This study investigates the effect of a new Chinese massage technique named “press-extension” on degenerative lumbar with disc herniation and facet joint dislocation, and provides a biomechanical explanation of this massage technique. Self-developed biomechanical software was used to establish a normal L1–S1 lumbar 3D FE model, which integrated the spine CT and MRI data-based anatomical structure. Then graphic technique is utilized to build a degenerative lumbar FE model with disc herniation and facet joint dislocation. According to the actual press-extension experiments, mechanic parameters are collected to set boundary condition for FE analysis. The result demonstrated that press-extension techniques bring the annuli fibrosi obvious induction effect, making the central nucleus pulposus forward close, increasing the pressure in front part. Study concludes that finite element modelling for lumbar spine is suitable for the analysis of press-extension technique impact on lumbar intervertebral disc biomechanics, to provide the basis for the disease mechanism of intervertebral disc herniation using press-extension technique.

    Indicating lumbar disc herniation via magnetic resonance imaging (MRI) T2 mapping in the posterior annulus fibrosus (AF). Sagittal T2 maps of 313 lumbar discs of 64 patients with low back pain were acquired at 3.0 Tesla (3T). The discs were rated according to disc herniation and bulging. Region of interest (ROI) analysis was performed on median, sagittal T2 maps. T2 values of the AF, in the most posterior 10% (PAF-10) and 20% of the disc (PAF-20), were compared. A significant increase in the T2 values of discs with herniations affecting the imaged area, compared to bulging discs and discs with lateral herniation, was shown in the PAF-10, where no association to the NP was apparent. The PAF-20 exhibited a moderate correlation to the nucleus pulposus (NP). High T2 values in the PAF-10 suggest the presence of disc herniation (DH). The results indicate that T2 values in the PAF-20 correspond more to changes in the NP.

    This case report presents a 37-year-old man with clinical signs of myelopathy almost 9 years after implantation of a Bryan disc prosthesis (Medtronic Sofamor Danek, Memphis, TN, USA) for C5/C6 soft disc herniation. As demonstrated on MRI and CT scan, spinal cord compression was caused by bony spurs due to heterotopic ossification posterior to the still moving prosthesis. The device, as well as the ectopic bone deposits, had to be removed because of myelopathy and its imminent aggravation. Conversion to anterior spondylodesis was performed.

  18. Structural brain alterations in patients with lumbar disc herniation: a preliminary study.

    Michael Luchtmann

    Full Text Available Chronic pain is one of the most common health complaints in industrial nations. For example, chronic low back pain (cLBP disables millions of people across the world and generates a tremendous economic burden. While previous studies provided evidence of widespread functional as well as structural brain alterations in chronic pain, little is known about cortical changes in patients suffering from lumbar disc herniation. We investigated morphometric alterations of the gray and white matter of the brain in patients suffering from LDH. The volumes of the gray and white matter of 12 LDH patients were determined in a prospective study and compared to the volumes of healthy controls to distinguish local differences. High-resolution MRI brain images of all participants were performed using a 3 Tesla MRI scanner. Voxel-based morphometry was used to investigate local differences in gray and white matter volume between patients suffering from LDH and healthy controls. LDH patients showed significantly reduced gray matter volume in the right anterolateral prefrontal cortex, the right temporal lobe, the left premotor cortex, the right caudate nucleus, and the right cerebellum as compared to healthy controls. Increased gray matter volume, however, was found in the right dorsal anterior cingulate cortex, the left precuneal cortex, the left fusiform gyrus, and the right brainstem. Additionally, small subcortical decreases of the white matter were found adjacent to the left prefrontal cortex, the right premotor cortex and in the anterior limb of the left internal capsule. We conclude that the lumbar disk herniation can lead to specific local alterations of the gray and white matter in the human brain. The investigation of LDH-induced brain alterations could provide further insight into the underlying nature of the chronification processes and could possibly identify prognostic factors that may improve the conservative as well as the operative treatment of the

    Full Text Available Objective To explore the techniques and curative effect of microsurgical procedures assisted by minimal exposure tubular retractor system (METRx in the treatment of lumbar disc herniation (LDH.  Methods A total of 51 LDH patients, including 24 patients with L4-5 herniation and 27 patients with L5-S1 herniation, underwent discectomy assisted by METRx system. The operation time, intraoperative blood loss, postoperative complications and hospital stay were recorded. Visual Analogue Scale (VAS and Oswestry Disability Index (ODI were used to evaluate the degree of low back pain before operation, one week, 3 months after operation, and in the last follow-up. Lumbar MRI was used to evaluate the decompression of spinal canal.  Results The success rate of operations in 51 cases was 98.04% (50/51. The average operation time was 125 min, the average intraoperative blood loss was 50 ml, the mean hospital stay was 5 d, all patients were followed up for 6-48 months (average 24 months. Compared with preoperation, both VAS and ODI scores decreased significantly one week after operation (P = 0.036, 0.029, 3 months after operation (P = 0.018, 0.023 and in the last follow-up (P = 0.007, 0.013. The improvement rate of ODI was 35.37% in the last follow-up. No infection, postoperative cerebrospinal fluid (CSF fistula, neurological defects or incision infection was found. One patient presented acute abdominalgia on the 2nd day after operation, and was diagnosed as annexitis. One patient showed nerve root irritation symptoms after operation caused by thick nerve root during the surgery. They were cured after symptomatic treatment.  Conclusions Microsurgical procedures for treating LDH assisted by METRx system can effectively relieve nerve root compression, protect the dural sac and nerve roots, and reduce surgical complications. DOI: 10.3969/j.issn.1672-6731.2016.04.008

    Prospective study. To analyze the sagittal balance after single-level cervical disc replacement (CDR) and range of motion (ROM). To define clinical and radiologic parameters those have a significant correlation with segmental and overall cervical curvature after CDR. Clinical outcomes and ROM after CDR with Mobi-C (LDR, Troyes, France) prosthesis have been documented in few studies. No earlier report of this prosthesis has studied correlations between static and dynamic parameters or those between static parameters and clinical outcomes. Forty patients were evaluated. Clinical outcome was assessed using the Short Form-36 questionnaire, Neck Disability Index, and a Visual Analog Scale. Spineview software (Surgiview, Paris, France) was used to investigate sagittal balance parameters and ROM. The mean follow-up was 24.3 months (range: 12 to 36 mo). Clinical outcomes were satisfactory. There was a significant improvement of Short Form-36, Neck Disability Index, and Visual Analog Scale scores. Mean ROM was 8.3 degrees preoperatively and 11.0 degrees postoperatively (P=0.013). Mean preoperative C2C7 curvature was 12.8 and 16.0 degrees at last follow-up (P=0.001). Mean preoperative functional spinal unit (FSU) angle was 2.3 and 5.3 degrees postoperatively (P<0.0001). Mean postoperative shell angle was 5.5 degrees. There was a significant correlation between postoperative C2C7 alignment and preoperative C2C7 alignment, change of C2C7 alignment, preoperative and postoperative FSU angle, and prosthesis shell angle. There was also a significant correlation between postoperative FSU angle and preoperative C2C7 alignment, preoperative FSU angle, change of FSU angle, and prosthesis shell angle. Regression analysis showed that prosthesis shell angle and preoperative FSU angle contributed significantly to postoperative FSU angle. Moreover, preoperative C2C7 alignment, preoperative FSU angle, postoperative FSU angle, and prosthesis shell angle contributed significantly to

    Full Text Available Low back pain in pregnancy is a common complaint. It has been reported that the pregnancy is an independent risk factor for lomber disc herniation and may worsen the existing herniation. Transient osteoporosis of the hip (TOH, is a rare, self-limiting and gestational disease of unknown cause. In this article, we report a case of acute lomber disc hernia and later bilateral temporal osteoporosis of the hip that was treated with conservative methods during the same gestational period. With this pathologic case it is emphasized that, two pathological phenomenon can be seen in the same patient at the same time. It should be kept in mind TOH and radiculopathy should be considered in the differential diagnosis in pregnant patients who complains back and hip pain.

    Full Text Available Background Low back pain is one of the most common debilitating disorders worldwide and the third cause of visiting a physician. One of the most common causes of low back pain is spinal disc herniation. Still there is no general agreement on the most effective treatment for it. Objectives This study aimed to determine the effect of Capsaicin cream on low back pain in patients with inter-vertebral disc herniation in Ahvaz. Patients and Methods This was a double blind clinical trial in which 43 patients with chronic low back pain, according to characteristics of the subjects, were randomly divided into two groups of treatment (n = 23 and control (n = 20. Data collection instruments included demographic specifications and visual analogue scale (VAS questionnaire completed on arrival and at the first, second and third weeks after intervention. The treatment and placebo groups used the ointment for three weeks and three times a day as a thin layer on the painful position. Data entered SPSS (version 18 and analyzed using the analytical descriptive statistics. Results There was a significant difference in the average pain intensity between the groups of study pre-and post-intervention (P = 0.0001 and the rate of using analgesics in the treatment group significantly decreased (P = 0.008. Also patients’ satisfaction was significantly different between the two groups using the ointment (P = 0.0001. Conclusions Capsaicin cream has beneficial effects on pain relieving and reducing analgesic use in patients with inter-vertebral disc herniation. Therefore, the ointment can be recommended in the treatment of low back pain caused by inter-vertebral disc herniation.

    Ossification of the posterior longitudinal ligament (OPLL) is a common spinal disorder that presents with or without cervical myelopathy. Furthermore, there is evidence suggesting that OPLL often coexists with cervical disc hernia (CDH), and that the latter is the more important compression factor. To raise the awareness of CDH in OPLL for spinal surgeons, we performed a retrospective study on 142 patients with radiologically proven OPLL who had received surgery between January 2004 and January 2008 in our hospital. Plain radiograph, three-dimensional computed tomography construction (3D CT), and magnetic resonance imaging (MRI) of the cervical spine were all performed. Twenty-six patients with obvious CDH (15 of segmental-type, nine of mixed-type, two of continuous-type) were selected via clinical and radiographic features, and intraoperative findings. By MRI, the most commonly involved level was C5/6, followed by C3/4, C4/5, and C6/7. The areas of greatest spinal cord compression were at the disc levels because of herniated cervical discs. Eight patients were decompressed via anterior cervical discectomy and fusion (ACDF), 13 patients via anterior cervical corpectomy and fusion (ACCF), and five patients via ACDF combined with posterior laminectomy and fusion. The outcomes were all favorable. In conclusion, surgeons should consider the potential for CDH when performing spinal cord decompression and deciding the surgical approach in patients presenting with OPLL.

    Full Text Available Acquired cerebellar tonsillar herniation and syringomyelia associated with posterior fossa mass lesions is an exception rather than the rule. In the present article, we describe the neuroimaging findings in a case of 28-year-old female patient presented with a history of paraesthesia involving right upper limb of 8-month duration. Magnetic resonance imaging showed a giant retrocerebellar arachnoid causing tonsillar herniation with cervical syringomyelia. The findings in the present case supports that the one of the primary mechanism for the development of syringomyelia may be the obstruction to the flow of cerebrospinal fluid causing alterations in the passage of extracellular fluid in the spinal cord and leading to syringomyelia.

    This study intends to evaluate whether regional common habits or differences in case-volume between surgeons are significative variables in the perioperative management of patients undergoing surgery for lumbar disc herniation. An e-mail survey was sent to all neurosurgeons working in Lombardy, Italy's most populated region. The survey consisted of 17 questions about the perioperative management of lumbar disc herniation. Forty-seven percent (47%) out of 206 Lombard neurosurgeons answered the survey. Although in some respects there is clear evidence in current literature on which is the best practice to adopt for an optimal management strategy, we noticed substantial differences between respondents, not only between hospitals but also between surgeons from the same hospital. Still, no differences were evident in a high vs low case-volume comparison. We identified no regional clusterization as for practical principles in the perioperative management of lumbar disc herniation and neither was case-volume a significative variable. Other causes may be relevant in the variability between the perioperative management and the outcomes achieved by different specialists.

    2014-07-01

    Although percutaneous cervical nucleoplasty (PCN) has been shown to be both safe and effective, its application is still debated. PCN applied in disk herniation has not been systematically reviewed before, resulting in a limited insight into its effectiveness and safety, and the quality of available evidence. Therefore, we systematically reviewed the evidence on the efficacy and safety of PCN in patients with a (contained) herniated disk. MEDLINE, EMBASE, and the Cochrane Library (Central Register of Controlled Trials) were searched for randomized controlled trials (RCTs) and nonrandomized studies using the following keywords: "Nucleoplasty," "Cervical," "Hernia," "Herniation," "Prolapse," "Protrusion," "Intervertebral disk," and "Percutaneous disk decompression." First, all articles were appraised for methodological quality, and then, RCTs were graded for the level of evidence according a best-evidence synthesis, because a meta-analysis was not possible. Finally, the RCTs' applicability and clinical relevance also was assessed. Of 75 identified abstracts, 10 full-text articles were included (3 RCTs and 7 nonrandomized studies). These studies represented a total of 1021 patients: 823 patients (≥ 892 disks) were treated by PCN. All studies showed low methodological quality, except for two. The level of evidence of the RCTs was graded as moderate, with low to moderate applicability and clinical relevance. All included studies showed PCN to be an effective and safe procedure in the treatment of (contained) herniated disks at short-, mid-, and long-term follow-up. However, the level of evidence is moderate and shows only low to moderate applicability and clinical relevance. © 2013 World Institute of Pain.

  9. Biomechanical analysis of the camelid cervical intervertebral disc

    Full Text Available Chronic low back pain (LBP is a prevalent global problem, which is often correlated with degenerative disc disease. The development and use of good, relevant animal models of the spine may improve treatment options for this condition. While no animal model is capable of reproducing the exact biology, anatomy, and biomechanics of the human spine, the quality of a particular animal model increases with the number of shared characteristics that are relevant to the human condition. The purpose of this study was to investigate the camelid (specifically, alpaca and llama cervical spine as a model of the human lumbar spine. Cervical spines were obtained from four alpacas and four llamas and individual segments were used for segmental flexibility/biomechanics and/or morphology/anatomy studies. Qualitative and quantitative data were compared for the alpaca and llama cervical spines, and human lumbar specimens in addition to other published large animal data. Results indicate that a camelid cervical intervertebral disc (IVD closely approximates the human lumbar disc with regard to size, spinal posture, and biomechanical flexibility. Specifically, compared with the human lumbar disc, the alpaca and llama cervical disc size are approximately 62%, 83%, and 75% with regard to area, depth, and width, respectively, and the disc flexibility is approximately 133%, 173%, and 254%, with regard to range of motion (ROM in axial-rotation, flexion-extension, and lateral-bending, respectively. These results, combined with the clinical report of disc degeneration in the llama lower cervical spine, suggest that the camelid cervical spine is potentially well suited for use as an animal model in biomechanical studies of the human lumbar spine.

  10. Traumatic Migration of the Bryan Cervical Disc Arthroplasty.

    Wagner, Scott C; Kang, Daniel G; Helgeson, Melvin D

    2016-02-01

    Study Design Case study. Objective To describe a case of dislodgment and migration of the Bryan Cervical Disc (Medtronic Sofamor Danek, Memphis, Tennessee, United States) arthroplasty more than 6 months after implantation secondary to low-energy trauma. Methods The inpatient, outpatient, and radiographic medical records of a patient with traumatic migration of the Bryan Cervical Disc arthroplasty were reviewed. The authors have no relevant disclosures to report. Results A 36-year-old man with chronic left upper extremity radiculopathy underwent uncomplicated Bryan Cervical Disc arthroplasty at C5-C6, with complete resolution of his symptoms. Approximately 6 months after his index procedure, he sustained low-energy trauma to the posterior cervical spine, after being struck by a book falling from a shelf. The injury forced his neck into flexion, and though he did not have recurrence of his radiculopathy symptoms, radiographs demonstrated anterior migration of the arthroplasty device. He underwent revision to anterior cervical diskectomy and fusion. Conclusions Although extremely rare, it is imperative that surgeons consider the potential for failure of osseous integration in patients undergoing cervical disk arthroplasty, even beyond 3 to 6 months postoperatively. This concern is especially relevant to press-fit or milled devices like the Bryan Cervical Disc arthroplasty, which lack direct fixation into adjacent vertebral bodies. We are considering modification of our postoperative protocol to improve protection of the device after implantation, even beyond 3 months postoperatively.

  11. High lumbar disc herniation coexisting with thoracic meningioma – an issue of differential diagnostic

    Dabija M.

    2017-09-01

    Full Text Available Meningiomas involving the spinal compartment are relatively rare compared to the intracranial ones representing between 7,5% and 12,5% of all CNS meningiomas, most of them being located in the intradural compartment respecting the pial layer of the spinal cord. Affecting ten times more often women rather than men, especially in the 5th and 6th decade of life, they pose a difficult diagnostic setting despite modern neuroimagistic techniques. The matter of correct differential diagnosis becomes even more doubtful, most of the patients of that age having also associative degenerative disorders, e.g. lumbar disc herniation. In this case proper neurological examination is the key as we will furthermore demonstrate - the MRI exam being targeted on the level of the sensorial dysfunction and not on the most common region which gives according pathology. The following case presentation can be considered “classic” representing a patient with all the criteria mentioned above including a long history of rheumatologic and chronic back pain medication for pain relief. We used the Frankel Scale for grading the pre- and postoperative neurological status. Acute neurological deterioration (under 24 hours is an important criteria for admission in emergency unit with around the clock exploration followed by microsurgical operation for the best possible outcome. Coexisting chronic lesions may be left behind and kept under surveillance, operated only when clear signs of health disorder appear. Because there are reported cases of thoracic meningiomas discovered after hernia disc operation and even cases of paraplegia due to a missed lesion, the aim of this article is to emphasize the importance of proper neurological examination preceding any MRI exploration.

    The objectives were to estimate the cut-off points for success on different sciatica outcome measures and to determine the success rate after an episode of sciatica by using these cut-offs. A 12-month multicenter observational study was conducted on 466 patients with sciatica and lumbar disc herniation. The cut-off values were estimated by ROC curve analyses using Completely recovered or Much better on a 7-point global change scale as external criterion for success. The cut-off values (references in brackets) at 12 months were leg pain VAS 17.5 (0-100), back pain VAS 22.5 (0-100), Sciatica Bothersomeness Index 6.5 (0-24), Maine-Seattle Back Questionnaire 4.5 (0-12), and the SF-36 subscales bodily pain 51.5, and physical functioning 81.7 (0-100, higher values indicate better health). In conclusion, the success rates at 12 months varied from 49 to 58% depending on the measure used. The proposed cut-offs may facilitate the comparison of success rates across studies.

  13. Comparison of diagnostic protocols and the equivalent effective dose in renal cancer and herniated lumbar disc

    1994-01-01

    Renal cancer (RC) and herniated lumbar disc (HLD) were the two pathologies selected for the study of the diagnostic protocols applied in different centers to determine how their variability is reflected in the effective equivalent dose (EED) and establish the optimal radiological protocol for diagnostic purposes, while using the lowest possible dose. On the basis of 222 case histories, it was observed that the EED resulting from the diagnosis of HLD can vary as much as a factor of 3(6.2-18.9 mSv). Likewise, the EED related to the diagnosis of RC can be modified by a factor of 1.5(32.6-48.3 mSv), depending on the diagnostic protocol employed. It can be considered that the optimal protocol to reach a diagnosis of HLD includes chest x-ray, lumbar spine x-ray and lumbar CT scan, while that required for the diagnosis of RC involves chest x-ray, IVU, abdominal CT scan and digital subtraction angiography. The optimization of the study protocols-especially the reduction of the number of exposures, modernization and quality control of the equipment, among other aspects, can reduce the EED by a factor of 2.

    The aim of this study is to assess the long-term clinical and radiological outcomes between minimally invasive (MIS) and conventional transforaminal lumbar interbody fusion (TLIF) in treating one-segment lumbar disc herniation (LDH). One-hundred and six patients treated by MIS-TLIF (50 cases) or conventional TLIF (56 cases) were included. Perioperative results were evaluated. Clinical outcomes were compared preoperatively and postoperatively. Radiologic parameters were based on a comparison of preoperative and three-year postoperative lumbar lordosis, segmental lordosis, sacral slope, the cross-sectional area of the paraspinal muscle and fusion rates. MIS TILF had significantly less blood, shorter operation time, mean return to work time and lower intramuscular pressure compared with the conventional group during the operation. VAS scores for lower back pain and ODI in MIS-TLIF were significantly decreased. The mean cross-sectional area of the paraspinal muscle was significantly decreased after surgery in the conventional TLIF group and no significant intragroup differences were established in the MIS-TLIF group. No significant differences were found in fusion rate, lumbar lordosis, segmental lordosis and sacral slope. Both MIS and conventional TLIF were beneficial for patients with LDH. However, MIS-TLIF manifests a great improvement in perioperative outcomes, low back pain, disability and preventing paraspinal muscle atrophy during the follow-up period observation.

    Full Text Available Background: Fenestration discectomy (FD is a common treatment method for lumber disc herniation (LDH, with good effects obtained. Nevertheless, it also causes many complications, such as lumbar instability, lumbago and back pain. Percutaneous endoscopic lumbar discectomy (PTED is a new minimally invasive treatment available for LDH with conservative therapy failure. At present, this technique has been carried out in China. The purpose of this study was to conduct a randomized prospective trial to compare the surgical outcomes of PTED and FD, explore the clinical application value of PTED, and discuss the operative manipulated skills of PTED.Methods: Totally 100 patients with LDH were enrolled from March 2014 to December 2015 and randomly divided into PTED group and FD group, 50 cases in each group. FD group received FD including epidural anesthesia, unilateral fenestration decompression, removal of nucleus pulposus, and nerve root decompression and release, while FTED group received PTED including local anesthesia, endoscopic removal of herniated nucleus pulposus and nerve root decompression and release. Both groups were followed up postoperatively. The duration of operation, incision length, postoperative bed-rest and hospital stay were compared between two groups, and the visual analogue scale (VAS, Oswestry disability index (ODI, and therapeutic effects at the final follow-up time were recorded and compared between 2 groups.Results: All patients completed the operation successfully. The surgical duration was similar between two groups (P>0.05. PTED group showed a less incision length and shorter postoperative bed-rest time and hospital stay than FD group (P<0.01. The VAS and ODI scores showed a significant decrease in both groups postoperatively when compared with operation before (P<0.05, but with no significant difference between two groups (P>0.05. Moreover, the excellent and good rate was higher in PTED group thanin FD group, with no

  16. Minimally invasive surgical procedures for the treatment of lumbar disc herniation

    Raspe, Heiner

    2005-11-01

    Full Text Available Introduction: In up to 30% of patients undergoing lumbar disc surgery for herniated or protruded discs outcomes are judged unfavourable. Over the last decades this problem has stimulated the development of a number of minimally-invasive operative procedures. The aim is to relieve pressure from compromised nerve roots by mechanically removing, dissolving or evaporating disc material while leaving bony structures and surrounding tissues as intact as possible. In Germany, there is hardly any utilisation data for these new procedures – data files from the statutory health insurances demonstrate that about 5% of all lumbar disc surgeries are performed using minimally-invasive techniques. Their real proportion is thought to be much higher because many procedures are offered by private hospitals and surgeries and are paid by private health insurers or patients themselves. So far no comprehensive assessment comparing efficacy, safety, effectiveness and cost-effectiveness of minimally-invasive lumbar disc surgery to standard procedures (microdiscectomy, open discectomy which could serve as a basis for coverage decisions, has been published in Germany. Objective: Against this background the aim of the following assessment is: * Based on published scientific literature assess safety, efficacy and effectiveness of minimally-invasive lumbar disc surgery compared to standard procedures. * To identify and critically appraise studies comparing costs and cost-effectiveness of minimally-invasive procedures to that of standard procedures. * If necessary identify research and evaluation needs and point out regulative needs within the German health care system. The assessment focusses on procedures that are used in elective lumbar disc surgery as alternative treatment options to microdiscectomy or open discectomy.

    Percutaneous Laser Nucleotomy (PLN) is a new treatment for disc herniation applying neodymium: yttrium-aluminum-garnet (Nd : YAG) laser through inserted needle into the center of the disc, with less invasion and shorter hospitalization than conventional open surgery. Serial MR images were observed in 21 patients before and after PLN. Canal occupying ratio (COR) and signal intensity (S.I.) of herniated disc were measured. Recovery rate of symptoms was 57.2%, based on scoring system proposed by the Japanese Orthopaedic Association for low-back pain (JOA score). The successful group (≥30% improvement in JOA score) showed rapid decrease in signal intensity, though the ineffective group ( 2 -weighted sequence. Increase of signal intensity was observed in some patients whose symptoms had become worse. This may correlate with increase of water content and inner pressure on the disc. There was no significant difference between pre- and post-COR; however, more than 10% COR decrease was observed in 7 patients and symptoms improved in these cases. Thus the prognosis of the patients treated with PLN can be assessed by MR findings. (author)

    Few studies have investigated prognostic factors for patients with sciatica, especially for patients treated without surgery. The aim of this study was to identify factors associated with non-success after 1 and 2 years of follow-up and to test the prognostic value of surgical treatment for sciatica. The study was a prospective multicentre observational study including 466 patients with sciatica and lumbar disc herniation. Potential prognostic factors were sociodemographic characteristics, back pain history, kinesiophobia, emotional distress, pain, comorbidity and clinical examination findings. Study participation did not alter treatment considerations for the patients in the clinics. Patients reported on the questionnaires if surgery of the disc herniation had been performed. Uni- and multivariate logistic regression analyses were used to evaluate factors associated with non-success, defined as Maine-Seattle Back Questionnaire score of ≥5 (0-12) (primary outcome) and Sciatica Bothersomeness Index ≥7 (0-24) (secondary outcome). Rates of non-success were at 1 and 2 years 44% and 39% for the main outcome and 47% and 42% for the secondary outcome. Approximately 1/3 of the patients were treated surgically. For the main outcome variable, in the final multivariate model non-success at 1 year was significantly associated with being male (OR 1.70 [95% CI; 1.06 - 2.73]), smoker (2.06 [1.31 - 3.25]), more back pain (1.0 [1.01 - 1.02]), more comorbid subjective health complaints (1.09 [1.03 - 1.15]), reduced tendon reflex (1.62 [1.03 - 2.56]), and not treated surgically (2.97 [1.75 - 5.04]). Further, factors significantly associated with non-success at 2 years were duration of back problems >; 1 year (1.92 [1.11 - 3.32]), duration of sciatica >; 3 months (2.30 [1.40 - 3.80]), more comorbid subjective health complaints (1.10 [1.03 - 1.17]) and kinesiophobia (1.04 [1.00 - 1.08]). For the secondary outcome variable

    The abrupt onset of respiratory failure secondary to asthma, known as acute asphyxial asthma (AAA) in adults, is uncommonly reported in children. Here, we report a case of a child with the acute onset of respiratory failure consistent with AAA complicated by the finding of a neck mass during resuscitation. This 11-year-old boy with a history of asthma initially presented in respiratory failure with altered mental status after the complaint of difficulty in breathing minutes before collapsing at home. Initially, his respiratory failure was thought to be secondary to status asthmaticus, and treatment was initiated accordingly. However, a neck mass noted during the resuscitation was cause for concern, and other etiologies for his respiratory failure were considered, including an airway obstructing neck mass. After pediatric surgery and anesthesia consultation for intubation and possible tracheostomy placement, general anesthesia was induced in the operating room with an inhaled anesthetic, with prompt resolution of the bronchspasm and decompression of the neck mass. Review of the imaging and clinical course ultimately yielded a diagnosis of cervical lung herniation as the etiology of his neck mass. We report this case of AAA and cervical lung herniation and a review of the literature of these 2 uncommon phenomena in children.

    2016-03-01

    We evaluated postoperative outcomes in patients who have lumbar foraminal or extraforaminal disc herniation (FELDH) and suggested the risk factors for poor outcomes. A total of 234 patients were selected for this study. Pre- and post-operative Visual Analogue Scale (VAS) and Korean version Oswestry Disability Index (KODI) were evaluated and the changes of both score were calculated. Outcome was defined as excellent, good, fair, and poor based on Mcnab classification. The percentage of superior facetectomy was calculated by using the Maro-view 5.4 Picture Archiving Communication System (PACS). Paramedian lumbar discectomy was performed in 180 patients and combined lumbar discectomy was performed in 54 patients. Paramedian lumbar discectomy group showed better outcome compared with combined discectomy group. p value of VAS change was 0.009 and KODI was 0.013. The average percentage of superior facetectomy was 33% (range, 0-79%) and it showed negative correlation with VAS and KODI changes (Pearson coefficient : -0.446 and -0.498, respectively). Excellent or good outcome cases (Group I) were 136 (58.1%) and fair or poor outcome cases (Group II) were 98 (41.9%). The percentage of superior facetectomy was 26.5% at Group I and 42.5% at Group II. There was significant difference in superior facetectomy percentage between Group I and II (p=0.000). This study demonstrated that paramedian lumbar discectomy with preservation of facet joints is an effective and good procedure for FELDH. At least 60% of facet should be preserved for excellent or good outcomes.

    Objective: To assess the long-term outcomes as well as the living quality of the patients with lumbar disc herniation (LDH) after the treatment of percutaneous lumbar discectomy (PLD), and to discuss the influential factors related to the long-term effectiveness. Methods: During the period of January 2000 to March 2002, PLD was performed in 129 patients with LDH. By using self-evaluation questionnaires of Oswestry disability index(ODI), Short Form-36(SF-36) and Japanese Orthopaedic Association(JOA) through letter or telephone interviews as well as the patients' initial medical records, the related clinical data were collected. Statistical analysis was conducted by using Wilcoxon's rank sum test, Chi-square test. Results: One hundred and eight patients (83.7%) were able to be followed up and 104 effective ques-tionnaires were collected. The mean follow-up time was (6.64±0.67) years, the excellent rate(ODI score, 0-20%) was 71.15%. The average scores of the JOA and SF-36 was 23.66±5.72 and 75.88±25.57, respectively. The scores of quality of life were obviously improved in all follow-up subscales. Conventional operations were carried out subsequently in 9 patients as they failed to respond to PLD. No complications related to PLD occurred in this study. The age,course of the disease and the patient's condition at the time of discharge might bear a relationship to long-term effectiveness. Conclusion: PLD is a safe and minimally-invasive technique for the treatment of LDH with quick and reliable effect. PLD can dramatically improve the quality of life. Many factors,such as the age, course of the disease and the patient's condition at the time of discharge,can affect the long-term outcomes. (authors)

    2016-01-01

    Full Text Available Background: Several prognostic factors exist influencing the outcome of surgical discectomy in the patients with lumbar disc herniation (LDH. The aim of this study is to evaluate the relationship between severity of preoperative impaired ankle reflex and outcomes of lumbar discectomy in the patients with L5-S1 LDH. Methods: We retrospectively evaluated 181 patients (108 male and 73 female who underwent simple discectomy in our orthopedic department from April 2009 to April 2013 and followed them up for more than one year. The mean age of the patients was 35.3±8.9 years old. Severity of reflex impairment was graded from 0 to 4+ and radicular pain and disability were assessed by visual analogue scale (VAS and Oswestry disability index (ODI questionnaires, respectively. Subjective satisfaction was also evaluated at the last follow-up visit. Chi-square and Kruskal-Wallis tests were used to compare qualitative variables. Results: Reflex impairment existed in 44.8% preoperatively that improved to 10% at the last follow-up visit. Statistical analyses could not find a significant relationship between the severity of impaired ankle reflex and sex or age (P=0.538 and P=0.709, respectively. There was a remarkable relationship between severity of reflex impairment and preoperative radicular pain or disability (P=0.012 and P=0.002, respectively. Kruskal-Wallis test showed that a more severity in ankle reflex impairment was associated with not only less improvement in postoperative pain and disability but also less satisfaction rate (P Conclusions: In the patients with L5-S1 LDH, more severe ankle reflex impairment is associated with less improvement in postoperative pain, disability, and subjective satisfaction.

    An association between aggrecan gene variable number of tandem repeats polymorphism (VNTR) and symptomatic lumbar disc herniation (LDH) has been reported in Chinese Han of Northern China, and obesity had previously been suspected of causing severe LDH. However, the interaction between aggrecan VNTR and obesity in symptomatic LDH has not been well studied. To examine the interaction between aggrecan VNTR and obesity in the susceptibility of symptomatic LDH, 259 participants participated in this study and donated a blood sample. The disease group comprised 61 patients already diagnosed with symptomatic LDH. The control group consisted of 198 healthy blood donors without symptoms of LDH who were not diagnosed with LDH. The aggrecan gene VNTR region was analyzed using polymerase chain reaction. The data indicated that between the two groups, participants carrying one or two alleles ≤25 repeats who were non-obese people showed a 1.057-fold increase in risk for symptomatic LDH (p = 0.895, changing the number of repeat alleles to 25 repeats who were obese people showed an 1.061-fold higher risk (p = 0.885, adding obesity to the mix alone did not demonstrably increase the risk of LDH), while participants carrying one or two alleles ≤25 repeats who were obese people showed a 4.667-fold increase in risk for symptomatic LDH (p = 0.0003, adding obesity plus changing the repeat allele number significantly increased the risk of LDH by 4.667). Overall, the findings suggest an underlying interaction between aggrecan VNTR and obesity in symptomatic LDH.

  5. Unsuspected spondylolysis in patients with lumbar disc herniation on MRI: The usefulness of posterior epidural fat.

    2012-12-01

    Lumbar disc herniation (LDH) at the level of non-displaced spondylolysis (isthmic spondylolisthesis) is an uncommon association rarely evaluated in the literature. In this study, authors examine whether the continuous posterior epidural fat between the dura mater and spinous process (continuous double-hump sign) at the level of LDH is a valuable tool to identify patients with non-displaced spondylolysis on MRI. Eighteen patients (group 1) presented at our department (2000-2010) with a LDH associated with an undiagnosed non-displaced spondylolysis on MRI. Spondylolysis was confirmed by direct visualization of the defect on CT-scan, dynamic radiography, MRI or at surgery. To validate this method, we made the same evaluation in 20 surgically treated patients (group 2) with a one-level LDH without spondylolysis. In all patients of group 1 spondylolysis was unsuspected on the MRI report. However, a positive "continuous double-hump sign" was seen in 16 patients. The spondylolysis was recognized on MRI in six cases, on CT-scan in nine cases and on dynamic radiography in one case. Two cases were diagnosed surgically. In group 2, only one patient had a positive "continuous double-hump sign". This new sign had a specificity of 95%, sensitivity of 88.88%, and accuracy of 92.10% for diagnosis of non-displaced spondylolysis. Non-displaced spondylolysis may be associated with adjacent LDH. Although uncommon, it is important for neurosurgeons to be aware of this association because of its implication on the therapeutical management. MRI is not always sufficient to recognize a non-displaced spondylolysis with certainty; however "continuous double-hump sign" may be used as a simple valuable diagnosis tool.

    Full Text Available The principle etiology of leg pain (sciatica from lumbar disc herniation is mechanical compression of the nerve root. Sciatica is reduced by decompression of the herniated disc, i.e., removing mechanical compression of the nerve root. Decompression surgery typically reduces sciatica more than lumbar back pain (LBP. Decompression surgery reduces mechanical compression of the nerve root. However, decompression surgery does not directly reduce sensitization of the sensory nerves in the epidural space and disc. In addition, sensory nerves in the annulus fibrosus and epidural space are not protected from topical interaction with pain mediators induced by decompression surgery. The secondary etiology of sciatica from lumbar disc herniation is sensitization of the nerve root. Sensitization of the nerve root results from a mechanical compression, b exposure to cellular pain mediators, and/or c exposure to biochemical pain mediators. Although decompression surgery reduces nerve root compression, sensory nerve sensitization often persists. These observations are consistent with continued exposure of tissue in the epidural space, including the nerve root, to increased cellular and biochemical pain mediators following surgery. A potential contributor to lumbar back pain (LBP is stimulation of sensory nerves in the annulus fibrosus by a cellular pain mediators and/or b biochemical pain mediators that accompany annular tears or disruption. Sensory fibers located in the outer one-third of the annulus fibrosus increase in number and depth as a result of disc herniation. The nucleus pulposus is comprised of material that can produce an autoimmune stimulation of the sensory nerves located in the annulus and epidural space leading to LBP. The sensory nerves of the annulus fibrosus and epidural space may be sensitized by topical exposure to cellular and biochemical pain mediators induced by lumbar surgery. Annulotomy or annular rupture allows the nucleus pulposus

    Full Text Available Objective: To study the difference of nerve conduction and injury degree in patients with lumbar disc herniation after microendoscopic discectomy and fenestration discectomy. Methods: Patients with single-segment lumbar disc herniation who were treated in Dazhou Central Hospital between May 2014 and February 2017 were selected as the research subjects, the history data were reviewed and the operation methods were referred to divide them into FD group and MED group who received fenestration discectomy and microendoscopic discectomy respectively. The conduction velocity of common peroneal nerve and tibial nerve were detected before operation and 4 weeks after operation; serum levels of nerve and muscle injury-related molecules as well as inflammation and stress-related molecules were detected before operation and 3 days after operation. Results: MNCV levels of common peroneal nerve and tibial nerve 4 weeks after operation as well as serum CRP, TNF-α, MDA and AOPP contents 3 d after operation of both groups of patients were significantly higher than those before operation, and the MNCV levels of common peroneal nerve and tibial nerve of MED group 4 weeks after operation were significantly higher than those of FD group while serum CRP, TNF-α, MDA and AOPP contents of MED group 3 d after operation were not significantly different from those of FD group; serum NSE, S100B, Tau, pNF-H, CPK, Myo and LDH contents of FD patients 3 d after operation were significantly higher than those before operation while serum NSE, S100B, Tau, pNF-H, CPK, Myo and LDH contents of MED group were not significantly different from those before operation. Conclusion: Microendoscopic discectomy for lumbar disc herniation can relieve the nerve and muscle injury, and is equivalent to fenestration discectomy in activating the systemic stress and inflammatory response.

    2017-01-01

    Cervical total disc replacement (TDR) is an established alternative to anterior cervical discectomy and fusion (ACDF) with excellent long-term outcomes and low failure rates. Cases of implant failure and migration are scarce and primarily limited to several years postoperatively. The authors report a case of anterior extrusion of a C4-C5 ProDisc-C (DePuy Synthes, West Chester, PA, USA) cervical artificial disc (CAD) 14 months after placement due to minor trauma. A 33-year-old female who had undergone C4-C5 CAD implantation presented with neck pain and spasm after experiencing a paragliding accident. A 4 mm anterior protrusion of the CAD was seen on x-ray. She underwent removal of the CAD followed by anterior fusion. Other cases of CAD extrusion in the literature are discussed and the device's durability and testing are considered. Overall, CAD extrusion is a rare event. This case is likely the result of insufficient osseous integration. Patients undergoing cervical TDR should avoid high-risk activities to prevent trauma that could compromise the disc's placement, and future design/research should focus on how to enhance osseous integration at the interface while minimizing excessive heterotopic ossification.

  9. The cauda equina syndrome in pregnant woman with a massive disc herniation.

    Antón Capitán, B; Malillos Torán, M

    Low back pain during pregnancy is a common cause of medical consultation. Although back pain is very common, the incidence of low back pain secondary to lumbar disk herniation in pregnancy is low (1: 10,000). Cauda equina syndrome from lumbar disk herniation is a serious complication. The delay in diagnosis and treatment can be a cause of chronic disability secondary to neurological sequelae. Numerous cases of disk herniation in pregnancy have been reported, however the association of a cauda equina syndrome as a result of disk herniation is rare. A case is presented of cauda equina syndrome in a pregnant woman at 12-week gestation. Copyright © 2015 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.

    2006-05-01

    Full Text Available Abstract Background Open discectomy is the standard surgical procedure in the treatment of patients with long-lasting sciatica caused by lumbar disc herniation. Minimally invasive approaches such as microendoscopic discectomy have gained attention in recent years. Reduced tissue trauma allows early ambulation, short hospital stay and quick resumption of daily activities. A comparative cost-effectiveness study has not been performed yet. We present the design of a randomised controlled trial on cost-effectiveness of microendoscopic discectomy versus conventional open discectomy in patients with lumbar disc herniation. Methods/Design Patients (age 18–70 years presenting with sciatica due to lumbar disc herniation lasting more than 6–8 weeks are included. Patients with disc herniation larger than 1/3 of the spinal canal diameter, or disc herniation less than 1/3 of the spinal canal diameter with concomitant lateral recess stenosis or sequestration, are eliglible for participation. Randomisation into microendoscopic discectomy or conventional unilateral transflaval discectomy will take place in the operating room after induction of anesthesia. The length of skin incision is equal in both groups. The primary outcome measure is the functional assessment of the patient, measured by the Roland Disability Questionnaire for Sciatica, at 8 weeks and 1 year after surgery. We will also evaluate several other outcome parameters, including perceived recovery, leg and back pain, incidence of re-operations, complications, serum creatine kinase, quality of life, medical consumption, absenteeism and costs. The study is a randomised prospective multi-institutional trial, in which two surgical techniques are compared in a parallel group design. Patients and research nurses are kept blinded of the allocated treatment during the follow-up period of 2 years. Discussion Currently, open discectomy is the golden standard in the surgical treatment of lumbar disc

    A prospective study. To investigate the association between microstructural nerve roots changes on diffusion tensor imaging (DTI) and clinical symptoms and their duration in patients with lumbar disc herniation. The ability to identify microstructural properties of the nervous system with DTI has been demonstrated in many studies. However, there are no data regarding the association between microstructural changes evaluated using DTI and symptoms assessed with the Oswestry Disability Index (ODI) and their duration. Forty consecutive patients with foraminal disc herniation affecting unilateral sacral 1 (S1) nerve roots were enrolled in this study. DTI with tractography was performed on the S1 nerve roots. Clinical symptoms were evaluated using an ODI questionnaire for each patient, and the duration of clinical symptoms was noted based on the earliest instance of leg pain and numbness. Mean fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values were calculated from tractography images. The mean FA value of the compressed lumbar nerve roots was significantly lower than the FA of the contralateral nerve roots (P leg pain, indicating that the microstructure of the nerve root has been damaged. 3.

    Magnetic resonance images (MRI) of diseased cervical and lumbar intervertebral discs involving both intrinsic and extrinsic cord lesions were examined using either a 0.15 T resistive or a 0.5 T superconductive magnetic imaging system. The vertebrae, intervertebral discs, and spinal cord were delineated on spin-echo (SE) images with a long repetition time (TR) and a short echo time (proton density-weighted image). Protrusion of degenerated intervertebral discs into the spinal canal was clearly demonstrated not only on sagittal but also on parasagittal and transverse views. The location of protruded discs and compression of the spinal cord, caudal sac, and nerve roots were well visualized three-dimensionally. Pathological features of intervertebral discs were well appreciated on T 2 -weighted images with long TR and SE pulse sequences. Degeneration of intervertebral discs resulted in decreased signal intensity in cases of lumbar disc involvement. For suspected myelomalacia, the intrinsic cord lesion resulting from traumatic disc protrusion appeared as focal low signal intensity on T 1 -weithed images and as somewhat high intensity on T 2 weighted images. The inversion recovery sequence with median inversion time displayed an inferior image of low contrast and was judged uninformative in comparison to SE imags. The findings showed MRI to be an essential diagnostic technique for spinal cord disorders. It clearly pinpoints the anatomic structures of the spine and the features of disc degeneration. Both extrinsic and intrinsic cord abnormalities can be identified with MRI. The selection of proper pulse sequences is required for the differentiation of the object of interest. (Namekawa, K)

    Prospective cohort study. Although lumbar radiculopathy is regarded as a specific diagnosis, the most effective treatment strategy is unclear. Commonly used treatments include transforaminal epidural steroid injections (TESIs) and Mechanical Diagnosis & Therapy (MDT), but no studies have investigated the effectiveness of this combination. MDT differentiates pain centralization (C) from non-centralization (NC), which indicates good vs. poor prognostic validity respectively. The main aims were 1) to determine changes in Mechanical Diagnosis and Therapy (MDT) pain response classifications after transforaminal epidural steroid injections (TESIs) in candidates for lumbar herniated disc surgery and 2) to evaluate differences in short and long term outcomes for patients with different pain response classifications. Candidates for lumbar herniated disc surgery were assessed with a MDT protocol and their pain response classified as centralizing or peripheralizing. For this study,only patients were eligible who showed a peripheralizing pain response at intake. All patients then received TESIs and were reassessed and classified using the MDT protocol, into groups according to pain response (resolved, centralizing, peripheralizing with less pain and peripheralising with severe pain). After receiving targeted treatment based on pain response after TESIs, ranging from advice, MDT or surgery, follow-up assessments were completed at discharge and at 12 months. The primary outcomes were disability (Roland-Morris Disability Questionnaire [RMDQ] for Sciatica), pain severity in leg (visual analogue scale [VAS], 0-100) and global perceived effect (GPE). Linear mixed-models were used to determine between-groups differences in outcome. A total of 77 patients with lumbar disc herniation and peripheralizing symptoms were included. Patients received an average of 2 (SD 0.7) TESIs. After TESIs, 17 patients (22%) were classified as peripheralizing with continuing severe pain.These patients

    We assessed the long-term outcomes of patients with lumbar disc herniation treated with percutaneous lumbar discectomy (PLD) or microendoscopic discectomy (MED). A retrospective study was performed in consecutive patients with lumbar disc herniation treated with PLD (n = 129) or MED (n = 101) in a single hospital from January 2000 to March 2002. All patients were followed up with MacNab criteria and self-evaluation questionnaires comprising the Oswestry Disability Index and Medical Outcomes Study 36-Item Short-Form Health Survey. Several statistical methods were used for analyses of the data, and a p value of <0.05 was considered to be statistically significant. A total of 104 patients (80.62%) with PLD and 82 patients (81.19%) with MED were eligible for analyses, with a mean follow-up period of 6.64 ± 0.67 years and 6.42 ± 0.51 years, respectively. There were no significant differences between the two groups in age, number of lesions, major symptoms and physical signs, and radiological findings. According to the MacNab criteria, 75.96% in the PLD group and 84.15% in the MED group achieved excellent or good results, respectively, this was statistically significant (p = 0.0402). With the Oswestry Disability Index questionnaires, the average scores and minimal disability, respectively, were 6.97 and 71.15% in the PLD group and 4.89 and 79.27% in the MED group. Total average scores of Medical Outcomes Study 36-Item Short-Form Health Survey were 75.88 vs. 81.86 in PLD group vs. MED group (p = 0.0582). The cost and length of hospitalization were higher or longer in MED group, a statistically significant difference (both p < 0.0001). Long-term complications were observed in two patients (2.44%) in the MED group, no such complications were observed in the PLD group. Both PLD and MED show an acceptable long-term efficacy for treatment of lumbar disc herniation. Compared with MED patients, long-term satisfaction is slightly lower in the PLD patients; complications

    We have developed a new method of three-dimensional MRI (3D-MRI) which enables a stereoscopic view of the spinal cord and both sides of spinal nerve roots in one image. Anatomical study for normal subjects, the S1 angulations and length were significantly smaller than those of others. The S1 DRG was oval and was the largest. In a pathological study the use of 3D-MRI defects the signal changes following damage to the spinal nerve roots or ganglion in lumbar disc herniation. With regard to signal changes in damaged root ganglion, a good correlation between root compression and root inflammation was detected by experiments. We are currently examining the relationship between the damaged root ganglion, pain sensory disturbance. This study showed that the dorsal root ganglion plays an important role in sensory control of radiculopathy on 3D-MRI. (author)

    2014-05-01

    To explore the reason, key diagnosic point and therapeutic method of the incisions fat colliquation or infections at early stage after operation of lumbar disc herniation. From July 2007 to May 2012, clinical data of 11 patients with incision fat liquefaction or early infection after lumbar discectomy were retrospectively analyzed. There were 5 males and 6 females with an average age of 43.1 years, and the mean time of incisions fat colliquation or infection was 5 days and a half after operation. The main clinical features included local wound pain aggravating, fervescence, fresh seepage in the wound, and blood inflammatory index increased, etc. The wound could heal at the first treatment stage or not was an evaluation standard of curative effect. All patients were followed up with an average period of 21 months. The wounds of 10 cases healed at the first stage without recurrence and complications. In 1 case infected by staphylococcus aureus, distal part of the wound present local red, swelling and with wave motion at 2 months after operation, staphylococcus aureus infection was confirmed after puncture and bacterial culture, and 1 thrum was found after local incision. The wound healed after change dressings for 1 week, without recurrence after followed up for 13 months. Preventing the risk factors before operation, minimizing invasive technique during operation reasonable antibiotics application for the lumbar operation reguiring placement objects, and correctly handling with wound after operation could prevent and reduce the incidence of incisions fat liquefaction or infection after operation of lumbar disc herniation. For incision fat liquefaction or infection, early diagnosis, debridement, VSD negative pressure irrigation and drainage, to choosing sensitive antibiotics according to the results of drug sensitivity, may contribute to wound early healing and decrease complication.

  2. Total disc replacement using tissue-engineered intervertebral discs in the canine cervical spine.

    Yu Moriguchi

    Full Text Available The most common reason that adults in the United States see their physician is lower back or neck pain secondary to degenerative disc disease. To date, approaches to treat degenerative disc disease are confined to purely mechanical devices designed to either eliminate or enable flexibility of the diseased motion segment. Tissue engineered intervertebral discs (TE-IVDs have been proposed as an alternative approach and have shown promise in replacing native IVD in the rodent tail spine. Here we demonstrate the efficacy of our TE-IVDs in the canine cervical spine. TE-IVD components were constructed using adult canine annulus fibrosis and nucleus pulposus cells seeded into collagen and alginate hydrogels, respectively. Seeded gels were formed into a single disc unit using molds designed from the geometry of the canine spine. Skeletally mature beagles underwent discectomy with whole IVD resection at levels between C3/4 and C6/7, and were then divided into two groups that received only discectomy or discectomy followed by implantation of TE-IVD. Stably implanted TE-IVDs demonstrated significant retention of disc height and physiological hydration compared to discectomy control. Both 4-week and 16-week histological assessments demonstrated chondrocytic cells surrounded by proteoglycan-rich matrices in the NP and by fibrocartilaginous matrices in the AF portions of implanted TE-IVDs. Integration into host tissue was confirmed over 16 weeks without any signs of immune reaction. Despite the significant biomechanical demands of the beagle cervical spine, our stably implanted TE-IVDs maintained their position, structure and hydration as well as disc height over 16 weeks in vivo.

    This study was to determine the prevalence of herniated intervertebral disc (HIVD) among Korean 19-year-old male in a large national sample and to compare the prevalence across geographic regions based on the data of conscription. We analyzed the conscription data of 615508 cases who were 19-year-old male, given an examination for conscription at nationwide Korean Military Manpower Administration from January 2008 to December 2009. Prevalence was determined by dividing the number of cases by the number of persons enrolled for 2 years. The analyses included of a cross-tabulations and nonparametric chi-square to compare the prevalence according to geographic region, disc severity, and conscription year. The prevalence of HIVD among 19-year-old male was 0.47%. Seoul had the highest prevalence of HIVD (total HIVD was 0.60%, and severe HIVD was 0.44%). The prevalence of HIVD was lower in Jeollabuk- do and Jeollanam-do (total HIVD was 0.25-0.27%, and severe HIVD was 0.16-0.17%). Annual prevalence of HIVD was slightly decreased in 2009, but geographic distribution annually was not different. In Korean 19-year-old male, the national prevalence of adolescent HIVD was 0.60%, but different geographic distribution was observed. It is quite possible that secondary contributing factor(s) interfere with the different geographic prevalence of HIVD.

    To examine rehabilitation preferences, participation and determinants for the choice of a certain rehabilitation setting (inpatient vs. outpatient) and setting-specific rehabilitation outcomes. The longitudinal observational study referred to 534 consecutive disc surgery patients (18-55 years). Face-to-face baseline interviews took place about 3.6 days after disc surgery during acute hospital stay. 486 patients also participated in a follow-up interview via telephone three months later (dropout-rate: 9%). The following instruments were used: depression and anxiety (Hospital Anxiety and Depression Scale), pain intensity (numeric analog scale), health-related quality of life (Short Form 36 Health Survey), subjective prognosis of gainful employment (SPE-scale) as well as questions on rehabilitation attendance, return to work, and amount of sick leave days. The vast majority of patients undergoing surgery for a herniated disc attended a post-hospital rehabilitation treatment program (93%). Thereby two-thirds of these patients took part in an inpatient rehabilitation program (67.9%). Physical, psychological, vocational and health-related quality of life characteristics differed widely before as well as after rehabilitation depending on the setting. Inpatient rehabilitees were significantly older, reported more pain, worse physical quality of life, more anxiety and depression and a worse subjective prognosis of gainful employment before rehabilitation.

    Objective To examine rehabilitation preferences, participation and determinants for the choice of a certain rehabilitation setting (inpatient vs. outpatient) and setting-specific rehabilitation outcomes. Methods The longitudinal observational study referred to 534 consecutive disc surgery patients (18–55 years). Face-to-face baseline interviews took place about 3.6 days after disc surgery during acute hospital stay. 486 patients also participated in a follow-up interview via telephone three months later (dropout-rate: 9%). The following instruments were used: depression and anxiety (Hospital Anxiety and Depression Scale), pain intensity (numeric analog scale), health-related quality of life (Short Form 36 Health Survey), subjective prognosis of gainful employment (SPE-scale) as well as questions on rehabilitation attendance, return to work, and amount of sick leave days. Results The vast majority of patients undergoing surgery for a herniated disc attended a post-hospital rehabilitation treatment program (93%). Thereby two-thirds of these patients took part in an inpatient rehabilitation program (67.9%). Physical, psychological, vocational and health-related quality of life characteristics differed widely before as well as after rehabilitation depending on the setting. Inpatient rehabilitees were significantly older, reported more pain, worse physical quality of life, more anxiety and depression and a worse subjective prognosis of gainful employment before rehabilitation. Pre-rehabilitation differences remained significant after rehabilitation. More than half of the outpatient rehabilitees (56%) compared to only one third of the inpatient rehabilitees (33%) returned to work three months after disc surgery (p<.001).

  7. A potential role for cell-based therapeutics in the treatment of intervertebral disc herniation.

    Ganey, Timothy M; Meisel, Hans Joerg

    Lower back pain and disc degeneration negatively affect quality of life and impose an enormous financial burden. An extensive body of scientific work has evolved that characterizes the disc, demonstrating spinal anatomy and morphology that contribute to risk and likely promote failure. Ultimately, matrix failure is responsible for mechanical failure, which in turn results in spinal compromise anatomically and subsequent pain. One intervening approach to breaking this sequence has been to repopulate the anatomy with autologous disc chondrocytes--cells capable of restoring the matrix and retaining the mechanical balance by which the disc functions. This strategy has been implemented both in patients and in animal models, and early results, although preliminary, support the premise as a positive approach.

    2003-05-01

    Full Text Available This study evaluated the efficacy and safety of titanium cage implants in cervical reconstruction to treat cervical spondylosis. Surgical data covered a 4-year period from January 1999 to December 2002 and included 34 consecutive patients, 20 men and 14 women, with ages ranging from 27 to 84 years (mean, 57 years. Patients underwent anterior cervical microdiscectomy followed by interbody fusion with a titanium cage implant (rather than an autogenous iliac crest bone graft at a single level ranging from C3 to C7. Twenty-one patients had a herniated intervertebral disc, nine had degenerative disc disease, and four had previous failed autograft fusion surgery that required revision. At clinical presentation, 26 patients had neck pain, 23 had radiculopathy, and nine had myelopathy. Diagnostic imaging studies included spinal dynamic roentgenography, computerized tomography, and magnetic resonance imaging. Lesions were located at C3-4 in seven cases, C4-5 in 14 cases, C5-6 in nine cases, and C6-7 in four cases. The follow-up period ranged from 7 to 48 months (mean, 26 months. Results revealed that the procedure was technically feasible. There were no intra- or postoperative complications. The most commonly used cage was 9 mm high. Imaging studies showed no cage instability, migration, or pseudarthrosis. Although mild subsidence (< 5 mm was observed in three cases, these patients preserved adequate postoperative cervical lordosis and the subsidence did not preclude a good clinical result. The advantages of this procedure over a similar operation using traditional tricorticate bone graft are: no graft morbidity; shorter operation time (mean time saved, 35 minutes; reduced blood loss (average blood loss, 75 mL; and early postoperative ambulation (mean, 4.7 hospital days. Nearly all patients rapidly lost their neck pain (92%, 24/26 and radicular symptoms (87%, 20/23 after surgery. The recovery rate from myelopathy was 44% (4/9. Progressive bony shield

    2017-01-01

    Objective To compare the clinical outcomes and biomechanical effects of total disc replacement (TDR) and posterior cervical foraminotomy (PCF) and to propose relative inclusion criteria. Methods Thirty-five patients who underwent surgery between 2006 and 2008 were included. All patients had single-level disease and only radiculopathy. The overall sagittal balance and angle and height of a functional segmental unit (FSU; upper and lower vertebral body of the operative lesion) were assessed by preoperative and follow-up radiographs. C2–7 range of motion (ROM), FSU, and the adjacent segment were also checked. Results The clinical outcome of TDR (group A) was tended to be superior to that of PCF (group B) without statistical significance. In the group A, preoperative and postoperative upper adjacent segment level motion values were 8.6±2.3 and 8.4±2.0, and lower level motion values were 8.4±2.2 and 8.3±1.9. Preoperative and postoperative FSU heights were 37.0±2.1 and 37.1±1.8. In the group B, upper level adjacent segment motion values were 8.1±2.6 and 8.2±2.8, and lower level motion values were 6.5±3.3 and 6.3±3.1. FSU heights were 37.1±2.0 and 36.2±1.8. The postoperative FSU motion and height changes were significant (p<0.05). The patient’s satisfaction rates for surgery were 88.2% in group A and 88.8% in group B. Conclusion TDR and PCF have favorable outcomes in patients with unilateral soft disc herniation. However, patients have different biomechanical backgrounds, so the patient’s biomechanical characteristics and economic status should be understood and treated using the optimal procedure.

    This study aims to investigate (1) motives, motivations and expectations regarding the choice for a specific rehabilitation setting after herniated disc surgery and (2) how rehabilitation-related motivations and expectations are associated with rehabilitation outcome (ability to work, health-related quality of life and satisfaction with rehabilitation) three months after disc surgery. The longitudinal cohort study refers to 452 disc surgery patients participating in a subsequent rehabilitation. Baseline interviews took part during acute hospital stay (pre-rehabilitation), follow-up interviews three months later (post-rehabilitation). Binary logistic regression and multiple linear regression analyses were applied. (1) Motives, motivations and expectations: Inpatient rehabilitation (IPR) patients stated "less effort/stress" (40.9%), more "relaxation and recreation" (39.1%) and greater "intensity of care and treatment" (37.0%) regarding their setting preference, whereas outpatient rehabilitation (OPR) patients indicated "family reasons" (45.3%), the wish for "staying in familiar environment" (35.9%) as well as "job-related reasons" (11.7%) as most relevant. IPR patients showed significantly higher motivation/expectation scores regarding regeneration (p job (p example, patients with less motivations/expectations to achieve improvements regarding "physical burden" showed a better health-related quality of life (p satisfaction with rehabilitation (OR = .806; p < .05). Rehabilitation-related motivations and expectations differed substantially between IPR and OPR patients before rehabilitation and were significantly associated with rehabilitation outcome. Taking motivational and expectation-related aspects into account may help to improve allocation procedures for different rehabilitation settings and may improve rehabilitation success.

  12. Effects of segmental traction therapy on lumbar disc herniation in patients with acute low back pain measured by magnetic resonance imaging: A single arm clinical trial.

    2017-01-01

    Low Back Pain (LBP) is considered as one of the most frequent disorders, which about 80% of adults experience in their lives. Lumbar disc herniation (LDH) is a cause for acute LBP. Among conservative treatments, traction is frequently used by clinicians to manage LBP resulting from LDH. However, there is still a lack of consensus about its efficacy. The purpose of this study was to evaluate the effects of segmental traction therapy on lumbar discs herniation, pain, lumbar range of motion (ROM), and back extensor muscles endurance in patients with acute LBP induced by LDH. Fifteen patients with acute LBP diagnosed by LDH participated in the present study. Participants undertook 15 sessions of segmental traction therapy along with conventional physiotherapy, 5 times a week for 3 weeks. Lumbar herniated mass size was measured before and after the treatment protocol using magnetic resonance imaging. Furthermore, pain, lumbar ROM and back muscle endurance were evaluated before and after the procedure using clinical outcome measures. Following the treatment protocol, herniated mass size and patients' pain were reduced significantly. In addition, lumbar flexion ROM showed a significant improvement. However, no significant change was observed for back extensor muscle endurance after the treatment procedure. The result of the present study showed segmental traction therapy might play an important role in the treatment of acute LBP stimulated by LDH.

    To investigate the early effectiveness of the Discover cervical artificial disc replacement in treating cervical spondylosis. Qualified for the selective standard, 24 patients with cervical spondylosis were treated between March 2010 and March 2011. Of 24 patients, 13 patients underwent anterior cervical decompression and fusion (ACDF) (ACDF group, between March 2010 and September 2010) and 11 patients underwent Discover cervical artificial disc replacement (CADR group, between September 2010 and March 2011). There was no significant difference in gender, age, disease duration, lesions typing, and affected segments between 2 groups (P > 0.05). The operative time, blood loss, and complications were recorded. Japanese Orthopaedic Association (JOA) scores, Neck Disability Index (NDI) scores, and Odom's scores were used to evaluate the postoperative effectiveness. In CADR group, the cervical range of motion (ROM) in all directions, and prosthesis eccentricity were measured before and after operation. Symptoms disappeared and no complication occurred after operation in the patients of 2 groups. The patients were followed up 12 to 18 months (mean, 15.3 months) in ACDF group and 6 to 12 months (mean, 9.6 months) in CADR group. The NDI scores in CADR group were significantly higher than those in ACDF group at 1, 3, and 6 months (P 0.05). According to Odom's score at last follow-up, the results were excellent in 6 cases, good in 4 cases, and fair in 3 cases with an excellent and good rate of 76.92% in ACDF group, and were excellent in 9 cases, good in 1 case, and poor in 1 case with an excellent and good rate of 90.91% in CADR group, showing no significant difference (chi2 = 3.000, P = 0.223). The patients in CADR group had significant limit of cervical joint ROM in flexion and extension and right bending at 1 month (P value (P < 0.05). Meanwhile, ROM in left bending were bigger than that in right bending in replaced segment and upper segment (P < 0.05), and the ROM

    To investigate the effects of surgical versus non-operative treatment on the physical function and safety of patients with lumbar disc herniation. PubMed, Cochrane Library, Embase, EBSCO, Web of Science, China National Knowledge Infrastructure and Chinese Biomedical Literature Database were searched from initiation to 15 May 2017. Randomized controlled trials that evaluated surgical versus non-operative treatment for patients with lumbar disc herniation were selected. The primary outcomes were pain and side-effects. Secondary outcomes were function and health-related quality of life. A random effects model was used to calculate the pooled mean difference with 95% confidence interval. A total of 19 articles that involved 2272 participants met the inclusion criteria. Compared with non-operative treatment, surgical treatment was more effective in lowering pain (short term: mean difference = -0.94, 95% confidence interval = -1.87 to -0.00; midterm: mean difference = -1.59, 95% confidence interval = -2.24 to -9.94), improving function (midterm: mean difference = -7.84, 95% confidence interval = -14.00 to -1.68; long term: mean difference = -12.21, 95% confidence interval = -23.90 to -0.52) and quality of life. The 36-item Short-Form Health Survey for physical functions (short term: mean difference = 6.25, 95% confidence interval = 0.43 to 12.08) and bodily pain (short term: mean difference = 5.42, 95% confidence interval = 0.40 to 10.45) was also utilized. No significant difference was observed in adverse events (mean difference = 0.82, 95% confidence interval = 0.28 to 2.38). Low-quality evidence suggested that surgical treatment is more effective than non-operative treatment in improving physical functions; no significant difference was observed in adverse events. No firm recommendation can be made due to instability of the summarized data.

    Voronina, D D; Kulikov, A G; Luppova, I A; Yarustovskaya, O V

    The objective of the present work was to rehabilitate more efficiently the patients who had undergone the surgical treatment for herniated discs in the lumbosacral spine by applying general magnetic therapy during the combined treatment. A total of 73 patients underwent the medical examination and treatment. The patients matched for age and sex presenting with similar clinical symptoms were divided into two groups. All of them received initial therapy that included medication, therapeutic physical exercises, and aquatic therapy. The patients in the main study group were given, in addition, general magnetic therapy. All the patients had their lower back examined before and after the treatment; moreover, they were asked to report their pain intensity based on the visual-analogue scale. The patients had their spinal and lower extremity temperature measured by means of thermal scanning with the use of remote infrared thermography and the non-invasive thermal imaging to check temperature fluctuations. To evaluate the psycho-emotional condition of the patients and to obtain their quality of life characteristics, they were asked to fill up the WAM (wellbeing, activity, mood) questionnaire; moreover, the disability Index was determined using the Oswestry questionnaire (version 2.1.), and the State-Trait Anxiety Inventory (STAI) was employed. 75.7% of the patients in the main group had the positive treatment results in the form of improvement of the affected movement skills, sensory processing abilities, and reflex functions as compared with the 58,3% success rate among the patients in the control groupd. Based on the data of non-invasive infrared thermal imaging, the patients of the main group had significantly lower post-treatment topical hyperthermia in the region of the surgical intervention in comparison with the controls which suggested the reduction of the severity of the inflammatory process and the manifestations of the muscular-tonic syndrome. Their temperature

    Isner-Horobeti, Marie-Eve; Dufour, Stéphane Pascal; Schaeffer, Michael; Sauleau, Erik; Vautravers, Philippe; Lecocq, Jehan; Dupeyron, Arnaud

    This study compared the effects of high-force versus low-force lumbar traction in the treatment of acute lumbar sciatica secondary to disc herniation. A randomized double blind trial was performed, and 17 subjects with acute lumbar sciatica secondary to disc herniation were assigned to high-force traction at 50% body weight (BW; LT50, n = 8) or low force traction at 10% BW (LT10, n = 9) for 10 sessions in 2 weeks. Radicular pain (visual analogue scale [VAS]), lumbo-pelvic-hip complex motion (finger-to-toe test), lumbar-spine mobility (Schöber-Macrae test), nerve root compression (straight-leg-raising test), disability (EIFEL score), drug consumption, and overall evaluation of each patient were measured at days 0, 7, 1, 4, and 28. Significant (P sciatica secondary to disc herniation who received 2 weeks of lumbar traction reported reduced radicular pain and functional impairment and improved well-being regardless of the traction force group to which they were assigned. The effects of the traction treatment were independent of the initial level of medication and appeared to be maintained at the 2-week follow-up. Copyright © 2016. Published by Elsevier Inc.

    Delgado-López, Pedro David; Rodríguez-Salazar, Antonio; Martín-Alonso, Javier; Martín-Velasco, Vicente

    Indication for surgery in lumbar disc herniation (LDH) varies widely depending on the geographical area. A literature review is presented on the natural history, role of physical examination, timing of surgery, evidence-based treatment, and conflicts of interests in LDH. Surgery is shown to provide significant faster relief of pain compared to conservative therapy, although the effect fades after a year. There is no treatment modality better than the rest in terms of pain control and neurological recovery, nor is there a surgical technique clearly superior to simple discectomy. The lack of sound scientific evidence on the surgical indication may contribute to its great geographical variability. Since LDH has a favourable natural history, neuroimaging and surgery should not be considered until after a 6-week period. It is necessary to specify and respect the surgical indications for LDH, avoiding conflicts of interests. Copyright © 2016 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

    Analysis of prospectively collected radiographic data. To investigate the influence of preoperative index-level range of motion (ROM) and disc height on postoperative ROM after cervical total disc arthroplasty (TDA) using compressible disc prostheses. Clinical studies demonstrate benefits of motion preservation over fusion; however, questions remain unanswered as to which preoperative factors have the ability to identify patients who are most likely to have good postoperative motion, which is the primary rationale for TDA. We analyzed prospectively collected data from a single-arm, multicenter study with 2-year follow up of 30 patients with 48 implanted levels. All received compressible cervical disc prostheses of 6 mm-height (M6C, Spinal Kinetics, Sunnyvale, CA). The influence of index-level preoperative disc height and ROM (each with two levels: below-median and above-median) on postoperative ROM was analyzed using 2 x 2 ANOVA. We further analyzed the radiographic outcomes of a subset of discs with preoperative height less than 3 mm, the so-called "collapsed" discs. Shorter (3.0 ± 0.4 mm) discs were significantly less mobile preoperatively than taller (4.4 ± 0.5 mm) discs (6.7° vs. 10.5°, P = 0.01). The postoperative ROM did not differ between the shorter and taller discs (5.6° vs. 5.0°, P = 0.63). Tall discs that were less mobile preoperatively had significantly smaller postoperative ROM than short discs with above-median preoperative mobility (P < 0.05). The "collapsed discs" (n = 8) were less mobile preoperatively compared with all discs combined (5.1° vs. 8.6°, P < 0.01). These discs were distracted to more than two times the preoperative height, from 2.6 to 5.7 mm, and had significantly greater postoperative ROM than all discs combined (7.6° vs. 5.3°, P < 0.05). We observed a significant interaction between preoperative index-level disc height and ROM in influencing postoperative ROM. Although limited by small sample

    2014-12-01

    Full Text Available Objective: Evaluate the impact of motor deficit (MD on pain, disability, depression and quality of life measures of patients with LDH prior to a specific treatment. Methods: A total of 254 consecutively enrolled patients with LDH associated to neurological impairment and sciatica who have not responded to conservative treatment were evaluated. After reviewing the exclusion criteria, 168 were included. Validated instruments were used in the preoperative period to evaluate: pain, disability, quality of life, anxiety and depression. Results: Normal motor strength was observed in 57 (33.9% patients and MD was observed in 111 (66.1% cases. No statistically significant differences were observed between patients with and without MD regarding gender, age, level of herniation, lateralization and workers' compensation. Regarding quality of life, no difference was detected in the eight domains of SF36 and between the PCS and MCS groups. The only difference observed was a higher disability rate in the MD group, with the mean ODI difference being 7.84 (CI 95%: 1.82â€"13.87; p=0.011. Motor weakness was observed in 35.1% (n=39/111 of patients who had abnormal results at the motor evaluation, being related to severity (X²: 46.058; p<0.0001. Conclusion: In patients with LDH without prior specific treatment, the presence of MD did not modify the pain, disability, depression measures and self-reported quality of life. The MD has no discriminative power for measures of quality of life in patients with LDH.

  2. Cut-Off Value for Pain Sensitivity Questionnaire in Predicting Surgical Success in Patients with Lumbar Disc Herniation.

    Parisa Azimi

    Full Text Available Various factors related to predict surgical success were studied; however, a standard cut-off point for the Pain Sensitivity Questionnaire (PSQ measure has not yet been established for a favorable surgical outcome for lumbar disc herniation (LDH. This study was to find the optimal cut-off point on the PSQ to distinguish surgical success in patients with LDH. A total of 154 patients with LDH consecutively referred to our clinic were enrolled into this prospective study between February 2011 and January 2014. All participants completed the PSQ. Patients completed the Oswestry Disability Index (ODI score before surgery, and at 2 years after surgery. Surgical success was defined as a 13-point improvement from the baseline ODI scores. The cut-off value for PSQ was determined by the receiver-operating characteristic curve (ROC. The mean age of patients was 49.3±9.6 years, and there were 80 women. The mean time for follow-up assessment was 31±5 months (range 24-35. Post-surgical success was 79.9% (n = 123 at 2 years follow up. The mean score for the total PSQ, PSQ-minor, and PSQ-moderate were 6.0 (SD = 1.6, 5.4 (SD = 1.9 and 6.5 (SD = 1.7, respectively. Total PSQ score was also significantly correlated with the total scores of the ODI. The optimal total PSQ cut-off point was determined as > 5.2 to predict surgical success in LDH patients, with 80.0% sensitivity and 75.6% specificity (AUC-0.814, 95% CI 0.703-0.926. This study showed that the PSQ could be considered a parameter for predicting surgical success in patients with LDH, and can be useful in clinical practice.

Thirty non-ambulatory paraparetic or paraplegic (with pain perception) dogs after decompressive surgery for TL-IVDH. Blinded, prospective clinical trial. Dogs were randomized (1:1) to a basic or intensive 14-day in-house rehabilitation protocol. Fourteen-day open field gait score (OFS) and coordination (regulatory index, RI) were primary outcomes. Secondary measures of gait, post-operative pain, and weight were compared at 14 and 42 days. Of 50 dogs assessed, 32 met inclusion criteria and 30 completed the protocol. There were no adverse events associated with rehabilitation. Median time to walking was 7.5 (2 - 37) days. Mean change in OFS by day 14 was 6.13 (confidence intervals: 4.88, 7.39, basic) versus 5.73 (4.94, 6.53, intensive) representing a treatment effect of -0.4 (-1.82, 1.02) which was not significant, P=.57. RI on day 14 was 55.13 (36.88, 73.38, basic) versus 51.65 (30.98, 72.33, intensive), a non-significant treatment effect of -3.47 (-29.81, 22.87), P = .79. There were no differences in secondary outcomes between groups. Early postoperative rehabilitation after surgery for TL-IVDH is safe but doesn't improve rate or level of recovery in dogs with incomplete SCI. Copyright © 2018 The Authors.

    2018-05-01

    Artificial cervical disc replacement is expected to maintain normal cervical biomechanics. At present, the effect of the Prestige LP prosthesis height on cervical biomechanics has not been thoroughly studied. This finite element study of the cervical biomechanics aims to predict how the parameters, like range of motion (ROM), adjacent intradiscal pressure, facet joint force, and bone-implant interface stress, are affected by different heights of Prestige LP prostheses. The finite element model of intact cervical spine (C3-C7) was obtained from our previous study, and the model was altered to implant Prestige LP prostheses at the C5-C6 level. The effects of the height of 5, 6, and 7 mm prosthesis replacement on ROM, adjacent intradiscal pressure, facet joint force, as well as the distribution of bone-implant interface stress were examined. ROM, adjacent intradiscal pressure, and facet joint force increased with the prosthesis height, whereas ROM and facet joint force decreased at C5-C6. The maximal stress on the inferior surface of the prostheses was greater than that on the superior surface, and the stresses increased with the prosthesis height. The biomechanical changes were slightly affected by the height of 5 and 6 mm prostheses, but were strongly affected by the 7-mm prosthesis. An appropriate height of the Prestige LP prosthesis can preserve normal ROM, adjacent intradiscal pressure, and facet joint force. Prostheses with a height of ≥2 mm than normal can lead to marked changes in the cervical biomechanics and bone-implant interface stress. Copyright © 2018 Elsevier Inc. All rights reserved.

    To study the relationship of upper thoracic spine degenerative disc contour changes on MR imaging in patients with neck pain. The relation between upper thoracic and cervical spine degenerative disc disease is not well established. One hundred and fifty-six patients referred with cervical pain were studied. There were 73 women and 77 men with a mean age of 48.6 +/- 14.6 years (range, 19 to 83 years). All MR studies were performed with a large 23-cm FOV covering at least from the body of T4 to the clivus. Discs were coded as normal, protrusion/bulge or extrusion. Degenerative thoracic disc contour changes were observed in 13.4% of patients with cervical pain. T2-3 was the most commonly affected level of the upper thoracic spine, with 15 bulge/protrusions and one extrusion. Upper degenerative thoracic disc contour changes presented in older patients than the cervical levels (Student-Newman-Keuls test, P < 0.001). Degenerative disc contour changes at the C7-T1, T1-2, T2-3 and T3-4 levels were significantly correlated ( P = 0.001), but unrelated to any other disc disease, patient's gender or age. Degenerative cervical disc disease was closely related together ( P < 0.001), but not with any thoracic disc. A statistically significant relation was found within the upper thoracic discs, reflecting common pathoanatomical changes. The absence of relation to cervical segments is probably due to differences in their pathomechanisms.

    A case-control study. To investigate the effectiveness of transforaminal percutaneous endoscopic discectomy (TPED) in Parkinson's disease (PD). Patients with PD frequently suffer from radiculopathy and low back pain. Additionally, they demonstrate higher complication rates after open spine surgery. However, the clinical outcome of minimally invasive techniques for lumbar discectomy, such as TPED, have not been established for this population. Patients diagnosed with lumbar disc hernia were divided into Group A (11 patients diagnosed with PD), and Group B (10 patients as the control, non-PD group). All patients underwent TPED. Indexes of visual analogue scale (VAS) for leg pain and Oswestry disability index (ODI) were assessed right before surgery and at six weeks, three months, six months and one year post-surgery. At the baseline visit, groups did not differ significantly with age (p=0.724), gender (p=0.835), level of operation (p=0.407), ODI (p=0.497) and VAS (p=0.772). Parkinson's patients had higher scores in ODI at every visit, but the outcome was statistically significant only at 3 months (p=0.004) and one year (p=0.007). Similarly, VAS measurements were higher at each time point, with the difference being significant at 3 (p<0.001), 6 (0.021), and 12 (p<0.001) months after surgery. At the end of a year of follow up, ODI was reduced by 49.6% (±16.7) in Group A and 59.2% (±8.0) in Group B (p=0.111), translating to a 79.5% (±13.0) and 91.5% (±4.1) average improvement in daily functionality (p=0.024). VAS was reduced by 59.1 mm (±11.8) in Group A and 62.2 mm (±7.4) in Group B (p=0.485), leading to an 85.3 % (±4.0) and 91.9% (±2.6) general improvement in leg pain (p<0.001). Our data indicate that TPED led to satisfactory improvement in leg pain and daily living in PD patients a year after surgery.

    Reported rate of infections after lumbar discectomy is 1%-15 %. This complication may result in disability or even the death. The aim of the study is to assess the rate of infection associated with lumbar discectomies when combined systemic and local antibiotic prophylaxis was employed. In this retrospective study we analyzed all patients operated for herniated lumbar disc from 2009 -2012 in our institute. Beside of receiving systemic prophylaxis with 2g of Cefazoline, all patients had their operative field irrigated at the end of operation with Amikacin sulfate injection. Wound was considered infected when local and systemic signs of infection were revealed and were associated with elevated ESR, leukocytosis and elevated CRP. Assessment of infection is done by neurosurgeon during the hospitalization and later at outpatient's clinic along postoperative course of three months. A total of 604 patients were operated, of those 285 patients (47.2 %) females and 319 males (52.8 %), 12 patients were operated on two levels (1.98 %). Average patient age was 32.5 years (range 20-65 years) Localization of herniated disc was: in L/2-L/3 20 patients or 3.3 %, the L/3-L/4 level 42 patients or 7 % , the L/4 -L /5 262 patients or 43.3 % at the level L/V- S/1 280 patients or 46.3 %. Three patients (0.49%) developed wound infection, two of them superficial infection only with local signs: local pain, redness and leakage. They were treated with oral antibiotics. One with deep wound infection. He presented with local and systemic signs and treated with i.v antibiotics. All the cultures from wound swab revealed staphylococcus aureus. Prophylaxis with systemic antibiotic (Cefazoline 2.0) intravenous administration 30 minutes before the incision and irrigation of operative field with local antibiotic Amikacine sulfate at the end of procedure reduces the infection rate in patients operated for herniated lumbar disc when compared with systemic antibiotic prophylaxis only.

    Objective: To discuss the indications, long-term outcomes and complications of microendoscopy discectomy (MED) and percutaneous lumbar discectomy (PLD) in treating central lumbar intervertebral disc herniation, and to compare the advantages of the two procedures. Methods: During the period from Jan. 2001 to March 2002 surgical procedure was carried out in sixty-three patients with single central lumbar disc herniation. The surgeries included MED (n=23) and PLD (n=40). The clinical data were retrospectively analyzed. The lesion site, the operation time, the blood loss in operation, the time staying in bed, the hospitalization cost and the postoperative hospitalization days were recorded. Oswestry disability index (ODI) and MacNab score were determined. Statistical analysis was performed by using pair sample t-test, κ-test and Fisher exact test. All patients were followed up. Results: A mean follow-up time was (5.1±0.6) years for patients receiving MED and (6.6±0.7) years for patients receiving PLD. The ODI and MacNab scores of patients receiving MED were better than these of patients receiving PLD. The hospitalization cost and the postoperative hospitalization days of MED group was higher and longer than these of PLD group, the differences between the two groups were statistically significant. The occurrence of long-term complication in MED group was 3.49%, while no complication was seen in PLD group. Conclusion: For the treatment of central lumbar intervertebral disc herniation, both MED and PLD are safe and minimally-invasive procedures with satisfactory long-term effectiveness, and the patients recover from clinical symptoms quickly. The PLD has used more common than MED. The performance of MED needs more skill and experience. Therefore, an interventional radiologist has to follow a relatively long learning curve in order to get the sufficient training and practice before he or she can master the technique of MED with full confidence. However, the long

    Most surgeons undertaking anterior cervical discectomy (ACD) introduce a bone graft or cage into the disc space when the decompression is complete. This is done to prevent segmental collapse, preserve cervical spine alignment and to promote fusion. We have conducted a prospective observational cohort study to investigate the relationship between loss of disc height, cervical spine alignment and clinical outcome in 140 patients undergoing ACD without inter-body graft or cage. At a minimum of 12 months after operation changes in disc space height and cervical spine alignment were correlated with clinical outcome measured by SF36, Neck Disability Index, and visual analogue neck and arm pain scores. There was no relationship between loss of disc height and outcome. Loss of the overall cervical lordosis was present in 71 patients and segmental kyphosis was found in 69. Analysis of clinical outcome showed no significant differences between patients with preserved and abnormal cervical alignment. Neither loss of disc height nor disturbance of cervical alignment compromised clinical outcome in the first year following ACD.

    Retrospective study of the difference of heterotopic ossification (HO) occurrence according to 3 different types of prosthesis. This study was designed to investigate the difference of HO occurrence according to different type of prosthesis. HO is defined as formation of the bone outside the skeletal system. Reported HO occurrence rate in cervical artificial disc replacement (ADR) was unexpectedly high and varied. But the influencing factors of HO in cervical ADR have not been elucidated well. The prosthesis-related factors for making difference of HO occurrence were investigated in this study. A total of 170 patients undergoing cervical arthroplasty with the Bryan cervical disc prosthesis (Medtroic Sofamor Danek, Memphis, TN), Mobi-C disc prosthesis (LDR Medical, Troyes, France), and ProDisc-C (Synthes, Inc., West Chester, PA) were included. Cervical lateral radiographs obtained before and after surgery were used to identify HO. Occurrence rate, occurrence-free period, location, and grade of HOs were investigated according to the different prosthesis. Each prosthesis group included patients as follows: Bryan disc, 81 patients; Mobi-C, 61 patients; and ProDisc-C, 28 patients. Overall HO rate was 40.6% (69 of 170 patients). Each HO occurrence rate by prosthesis was as follows: the Bryan disc group, 21.0%; Mobi-C group, 52.5%; and the ProDisc-C group, 71.4%. In the survival analysis, all patients showed 27.1 +/- 3.7 months as the median survival. The Bryan disc group showed statistically longer survival (48.4 +/- 7.4 months) than the other groups. Occurrence of HO is an inevitable postoperative complication after cervical ADR. The occurrence rate of HO was higher than our expectation. Moreover, definite differences in occurrence rate according to the prosthesis type were identified by this study.

    Full Text Available Background: Ninety percent of all people sometimes during their lives experience low back pain, and 30-40% develops radicular leg pain with the sciatica characteristics. Although for clinical diagnosis of lumbar disc herniation (LDH straight leg raising (SLR test in 85-90% of cases indicates LDH, but in our practice with LDH patients this test is frequently negative despite radicular leg pain due to LDH. Hence, we decided to evaluate this test in LDH in different age groups. Materials and Methods: All patients with leg pain referring to neurosurgery clinic were enrolled. Those with a history of pain other than sciatica excluded and SLR test and magnetic resonance imaging (MRI of the lumbosacral spine performed. The patients with negative MRI findings excluded and finally 269 patients with true sciatica and positive MRI were included. SLR tests were performed for different age groups. Results: Of 269 patients, 167 were male. The age range was 16-80 years. The most involved levels were L5-S1 (47% and L4-L5 (42%, respectively. The rate of positive SLR result, which was 100%, 87% and 82% for 10-19, 20-29 and 30-39 years age group respectively. With an increment of age, the rate of positive test regularly declined . The chance of positive SLR in men is 1.3 times the women (odds ratio [OR] 2.4; 95% confidence interval [CI] = 1.265-4.557; P = 0.007. Increasing the age has suppression effect in positivity of SLR so that for each 1-year the chance of SLR become 0.27 times less to become positive and this is also statically meaningful (OR = 0.271;95% CI = 0.188-0.391; P,0.001. The chance of positive SLR for patients under 60 is 5.4 folds more than patients above 60 years old (OR = 5.4; 95% CI = 4-8.3; P, 0.001. Conclusion: Age, sex (male, and disk level had statistically the effect on SLR positive test.

    The aim of this study was to assess the efficacy of the Artcure Diffusional Patch, which contains a mixture of 6 herbal oils (oleum thymi, oleum limonis, oleum nigra, oleum rosmarini, oleum chamomilla, oleum lauriexpressum) and has a hypoosmolar lipid structure, in the conservative treatment of lumbar disc herniation patients and to show the advantages and/or possibility of using this as an alternative method to surgery. Of the 120 patients enrolled, 79 clinically diagnosed patients were included in the study. Clinical evaluations were performed on patients who had findings of protrusion or extrusion in their magnetic resonance results. The treatment group was treated with the Artcure Diffusional Patch while the control group received a placebo transdermal diffusional patch. The functional state of patients was measured using the Oswestry Disability Index and pain intensity was measured with a visual analog scale as primary outcomes. Secondary outcomes of the study were Lasegue's sign, the femoral stretching test, and paravertebral muscle spasm. The treatment group showed a dramatic recovery in the first month following the application in regards to Oswestry Disability Index scores and visual analog scale values. The patients treated with the Artcure Diffusional Patch showed a statistically significant difference in recovery as compared to the control group. These findings suggest that the Artcure Diffusional Patch may be an alternative for the conservative treatment of lumbar disc herniation with radiculopathy.

The Mobi-C disc prosthesis, one of many Food and Drug Administration (FDA-approved devices for CDA, is the only FDA-approved prosthesis for two-level CDA. Hence, it may allow for improved outcomes compared with multilevel fusion procedures.Purpose: To critically assess the available literature on CDA with the Mobi-C prosthesis, with a focus on two-level CDA.Methods: All clinical articles involving the Mobi-C disc prosthesis for CDA through September 1, 2014 were identified on Medline. Any paper that presented Mobi-C CDA clinical results was included. Study design, sample size, length of follow-up, use of statistical analysis, quality of life outcome scores, conflict of interest, and complications were recorded.Results: Fifteen studies were included that investigated Mobi-C CDA, only one of which was a level Ib randomized control trial. All studies included showed non-inferiority of one-level Mobi-C CDA to one-level anterior cervical discectomy and fusion (ACDF. Only one study analyzed outcomes of one-level versus two-level Mobi-C CDA, and only one study analyzed two-level Mobi-C CDA versus two-level ACDF. In comparison with other cervical disc prostheses, the Mobi-C prosthesis is associated with higher rates of heterotopic ossification (HO. Studies with conflicts of interest reported lower rates of HO. Adjacent segment degeneration or disease, along with other complications, were not assessed in most studies.Conclusion: One-level Mobi-C CDA is non-inferior, but not superior, to one-level ACDF for patients

    2017-12-01

    Around 90% of sciatica cases are due to a herniated intervertebral disc in the lumbar region. Ankle acupuncture (AA) has been reported to be effective in the treatment of acute nonspecific low back pain. This study aims to evaluate the efficacy of a single session of ankle acupuncture for disc-related sciatica. This will be a double-blinded, randomized controlled clinical trial. Patients diagnosed with disc-related sciatica will be randomly divided into 3 parallel groups. The treatment group (n = 30) will receive ankle acupuncture. The 2 control groups will either undergo traditional needle manipulation (n = 30) or sham acupuncture (n = 30) at the same point as the treatment group. The primary outcome will be pain intensity on a visual analog scale (VAS). The secondary outcomes will be paresthesia intensity on a VAS and the Abbreviated Acceptability Rating Profile (AAPR). The success of blinding will be evaluated, and the needle-induced sensation and adverse events will be recorded. All outcomes will be evaluated before, during, and after the treatment. This study will determine the immediate effect and specificity of ankle acupuncture for the treatment of disc-related sciatica. We anticipate that ankle acupuncture might be more effective than traditional needle manipulation or sham acupuncture. ChiCTR-IPR-15007127 (http://www.chictr.org.cn/showprojen.aspx?proj=11989).

    To observe the effect of medicinal-cake-separated moxibustion combined with acupuncture on back-leg activities and plasma substance P (SP) levels in patients with lumbar disc herniation, so as to reveal its mechanism underlying pain relief. A total of 114 patients with lumbar disc herniation were randomly divided into control group (n=56) and treatment group (n=58) according to a random digits table. Patients of the control group were treated by manual acupuncture stimulation of main acupoints Jiaji (EX-B 2), Huantiao (GB 30, affected side), Chengshan (BL 57, affected side), Kunlun (BL 60, affected side), and supplemented acupoints Yanglingquan (GB 34), Weizhong (BL 40) and Zusanli (ST 36) in combination with wheat-flour-cake separated moxibustion at the main acupoints, and patients of the treatment group were treated by medicinal-cake [Chuanwu (Radix Aconiti), Caowu (Radix Aconiti Kusnezoffii), Ruxiang (Olibanum), etc. ]-separated moxibustion in combination with manual acupuncture stimulation of the same acupoints mentioned above. Acupuncture treatment was conducted for 30 min, followed by moxibustion for 15 min. The treatment was given once daily for 10 days. The patients' back-leg functional activity ability was assessed using straight-leg raising test, and the pain state assessed using visual analogue scale (VAS) and Japanese Orthopaedic Association (JOA) scores, respectively. The therapeutic effect was evaluated by using "Crite- ria for Diagnosis and Outcome Evaluation of Clinical Disorders or Syndromes of Chinese Medicine" issued in 1994 and plasma SP content was detected by radioimmunoassay. After the therapy, the back-leg activity score and JOA score of both groups were significantly higher than those of pre-treatment in the same one group (Pcake-separated moxibustion therapy can ame- liorate pain severity and functional activity of the back-leg pain patients with lumbar disc hernia, which may be related to its effect in reducing blood SP level.

  19. Efficacy and safety of Mobi-C cervical artificial disc versus anterior discectomy and fusion in patients with symptomatic degenerative disc disease: A meta-analysis.

    2017-12-01

    Total disc replacement (TDR) using Mobi-C cervical artificial disc might be promising to treat symptomatic degenerative disc disease. However, the results remained controversial. We conducted a systematic review and meta-analysis to compare the efficacy and safety of Mobi-C cervical artificial disc and anterior cervical discectomy and fusion (ACDF) in patients with symptomatic degenerative disc disease. PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of Mobi-C versus ACDF on the treatment of symptomatic degenerative disc disease were included. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. The primary outcomes were neck disability index (NDI) score, patient satisfaction, and subsequent surgical intervention. Meta-analysis was performed using the random-effect model. Four RCTs were included in the meta-analysis. Overall, compared with ACDF surgery for symptomatic degenerative disc disease, TDR using Mobi-C was associated with a significantly increased NDI score (Std. mean difference = 0.32; 95% CI = 0.10-0.53; P = .004), patient satisfaction (odds risk [OR] = 2.75; 95% confidence interval [CI] = 1.43-5.27; P = .002), and reduced subsequent surgical intervention (OR = 0.20; 95% CI = 0.11-0.37; P degenerative disc disease, TDR using Mobi-C cervical artificial disc resulted in a significantly improved NDI score, patient satisfaction, and reduced subsequent surgical intervention. There was no significant difference of neurological deterioration, radiographic success, and overall success between TDR using Mobi-C cervical artificial disc versus ACDF surgery. TDR using Mobi-C cervical artificial disc should be recommended for the treatment of symptomatic degenerative disc disease.

    To identify characteristics of chondrodystrophoid and nonchondrodystrophoid small-breed dogs with cervical intervertebral disk herniation (IVDH). Retrospective case series. 187 small-breed (≤ 15 kg [33 lb]) dogs that underwent surgery because of cervical IVDH. Medical records were reviewed for information on breed, sex, age, weight, location of affected intervertebral disks, duration and severity of neurologic signs, and recovery time. 55 of the 187 (29.4%) dogs were Beagles. The most frequently affected intervertebral disk was C2-3 (81/253 [32.0%]), and this was the more frequently affected intervertebral disk in dogs of several chondrodystrophoid breeds, including Beagles (29/66 [43.9%]), Dachshunds (13/37 [35.1%]), Shih Tzus (16/41 [39.0%]), and Pekingese (3/10 [30.0%]). However, caudal disks (C5-6 or C6-7) were more frequently affected in Yorkshire Terriers (13/24 [54.2%]) and Chihuahuas (9/13 [69%]). Shih Tzus and Yorkshire Terriers were significantly older at the time of surgery (mean ± SD age, 9.6 ± 2.3 years and 9.5 ± 2.5 years, respectively) than were Pomeranians (6.2 ± 2.3 years), and Yorkshire Terriers had a significantly higher number of affected disks (2.0 ± 0.9) than did Dachshunds (1.1 ± 0.3). Mean recovery time was significantly longer in Yorkshire Terriers (36.7 ± 13.0 days) than in Beagles (16.5 ± 17.1 days), Shih Tzus (17.8 ± 14.5 days), or Chihuahuas (12.2 ± 7. 2 days). Results suggested that there may be breed-specific differences in the characteristics of cervical IVDH in small-breed dogs.

    Objective: To observe the short and intermediate-term clinical outcomes of porous coated motion (PCM) cervical prosthesis in the treatment of cervical spondylosis. Methods: The 12 (13 levels) patients who were suffered spondylotic myelopathy with PCM cervical prosthesis were treated. Evaluate the clinical outcome by comparing the JOA scores, the position of prosthesis,rotation of motion, the heterotopic ossification and Odom's scales. Results: After the average 6.5 months(3 ∼ 12 months) follow-up, the JOA scales raised from 8.35 ± 1.10 preoperatively to 15.88 ± 0.73 postoperatively (P 0.05). There was no occurrence of failures of prosthesis such as subsidence, loosening, or excursion. Heterotopic ossification was also absent. Conclusion: The clinical outcomes for cervical disc replacement in the treatment of cervical spondylopathy are satisfied. (authors)

    Degeneration of intervertebral discs and facet joints is one of the most frequently encountered spinal disorders. In order to describe and quantify degeneration and evaluate a possible relationship between degeneration and biomechanical parameters, e.g., the intervertebral range of motion and intradiscal pressure, a scoring system for degeneration is mandatory. However, few scoring systems for the assessment of degeneration of the cervical spine exist. Therefore, two separate objective scoring systems to qualitatively and quantitatively assess the degree of cervical intervertebral disc and facet joint degeneration were developed and validated. The scoring system for cervical disc degeneration consists of three variables which are individually scored on neutral lateral radiographs: "height loss" (0-4 points), "anterior osteophytes" (0-3 points) and "endplate sclerosis" (0-2 points). The scoring system for facet joint degeneration consists of four variables which are individually scored on neutral computed tomography scans: "hypertrophy" (0-2 points), "osteophytes" (0-1 point), "irregularity" on the articular surface (0-1 point) and "joint space narrowing" (0-1 point). Each variable contributes with varying importance to the overall degeneration score (max 9 points for the scoring system of cervical disc degeneration and max 5 points for facet joint degeneration). Degeneration of 20 discs and facet joints of 20 patients was blindly assessed by four raters: two neurosurgeons (one senior and one junior) and two radiologists (one senior and one junior), firstly based on first subjective impression and secondly using the scoring systems. Measurement errors and inter- and intra-rater agreement were determined. The measurement error of the scoring system for cervical disc degeneration was 11.1 versus 17.9% of the subjective impression results. This scoring system showed excellent intra-rater agreement (ICC = 0.86, 0.75-0.93) and excellent inter-rater agreement (ICC = 0

    Full Text Available Worldwide, accidents are one of the main causes of illness in developed and undeveloped socio-economic countries. Additive Manufacturing (AM technologies bring extremely useful and advantageous applications for the new neurosurgical procedures. Because the surgical insertion of devices for cervical disc replacement is very difficult, the development of new devices that can minimize these disadvantages, are needed. The aim of this paper was to improve the characteristics of an implant for cervical intervertebral disc replacement, a model based on an existing implant. A cervical cage designed for stabilization and arthrodesis between the cervical vertebrae was analyzed. A new design of a cage that have some improvements, useful for patient safety, as well as for facilitating the surgery was developed. The new proposed design was verified through Fine Element Analysis.

  4. [Longterm results of cervical arthroplasty with disc prosthesis. A literature review].

    Fransen, P; Schils, F

    2014-01-01

    Cervical arthroplasty has now been performed for over 10 years. Despite the large number of implanted artificial discs, the quality of the published studies is weak, and very few report a follow up exceeding two years. We reviewed the literature on cervical total disc replacement, focusing on publications reporting a follow-up of more than two years. The selection of patients, the type of implant and the surgical technique seem to influence greatly the quality of the clinical and radiological results. The occurrence of heterotopic ossifications around the implant seems to be the rule rather than the exception. Wear debris are likely to be observed in the vicinity of the prosthesis. Most long term studies also report a progressive decrease in the range of motion of the prosthesis, although without influence on the clinical evolution. It seems reasonable to say that cervical disc prosthesis is not inferior to discectomy and fusion, and that these implants allow a short term preservation of cervical mobility, but the efficacy in preventing adjacent segment disease or a favourable costleffectiveness ratio have yet to be demonstrated. A more widespread use of cervical disc prosthesis can only be suggested when these questions have been answered by long term follow-up studies.

    Heterotopic ossification (HO) is defined as a formation of bone outside the skeletal system. The reported HO occurrence rate in cervical artificial disc replacement (ADR) is unexpectedly high and is known to vary. However, the predisposing factors for HO in cervical ADR have not yet been elucidated. Investigation of the predisposing factors of HO in cervical arthroplasty and the relationship between degeneration of the cervical spine and HO occurrence. Retrospective study to discover predisposing factors of HO in cervical arthroplasty. A total of 170 patients who underwent cervical ADR were enrolled including full follow-up clinical and radiologic data. Radiologic outcomes were assessed by identification of HOs according to McAfee's classifications. This study enrolled a total of 170 patients who underwent cervical ADR. Pre-existing degenerative change included anterior or posterior osteophytes, ossification of the anterior longitudinal ligament, posterior longitudinal ligament, or ligamentum nuchae. The relationships between basic patient data, pre-existing degenerative change, and HO were investigated using linear logistic regression analysis. Among all 170 patients, HO was found in 69 patients (40.6%). Among the postulated predisposing factors, only male gender and artificial disc device type were shown to be statistically significant. Unexpectedly, preoperative degenerative changes in the cervical spine exerted no significant influence on the occurrence of HOs. The odds ratio of male gender compared with female gender was 2.117. With regard to device type, the odds ratios of Mobi-C (LDR medical, Troyes, France) and ProDisc-C (Synthes, Inc., West Chester, PA, USA) were 5.262 and 7.449, respectively, compared with the Bryan disc. Definite differences in occurrence rate according to the gender of patients and the prosthesis type were identified in this study. Moreover, factors indefinably expected to influence HO in the past were not shown to be risk factors

    Artificial cervical disc replacement surgery has become an effective and main treatment method for cervical disease, which has become a more common and serious problem for people with sedentary work. To improve cervical disc replacement surgery significantly, a 6-DOF parallel bone-grinding robot is developed for cervical bone-grinding by image navigation and surgical plan. The bone-grinding robot including mechanical design and low level control is designed. The bone-grinding robot navigation is realized by optical positioning with spatial registration coordinate system defined. And a parametric robot bone-grinding plan and high level control have been developed for plane grinding for cervical top endplate and tail endplate grinding by a cylindrical grinding drill and spherical grinding for two articular surfaces of bones by a ball grinding drill. Finally, the surgical flow for a robot-assisted cervical disc replacement surgery procedure is present. The final experiments results verified the key technologies and performance of the robot-assisted surgery system concept excellently, which points out a promising clinical application with higher operability. Finally, study innovations, study limitations, and future works of this present study are discussed, and conclusions of this paper are also summarized further. This bone-grinding robot is still in the initial stage, and there are many problems to be solved from a clinical point of view. Moreover, the technique is promising and can give a good support for surgeons in future clinical work.

    This study is aimed to investigate the changes of nerve root functions during the straight leg raising (SLR) test in vivo. To investigate the relationship between nerve root movement and the electrophysiological values during an intraoperative SLR test. The SLR test is one of the most significant signs for making a clinical diagnosis of lumbar disc herniation. A recent study showed that intraradicular blood flow apparently decreased during the SLR test in patients with disc herniation. The study included 32 patients who underwent microdiscectomy. During the surgery, the nerve root motion affected by the hernia was observed during the SLR test. The patients' legs were allowed to hang down to the angle at which sciatica had occurred and the change of nerve root action potentials was measured. After removal of the hernia, a similar procedure was repeated. The periradicular specimens collected during surgery were examined by light and electron microscope. In all patients intraoperative microscopy revealed that the hernia was adherent to the dura mater of the nerve roots. During the SLR test, the limitation of nerve root movement occurred by periradicular adhesive tissue and amplitude of action potential showed a sharp decrease at the angle that produced sciatica. After removal of the hernia, all the patients showed smooth gliding of the nerve roots during the test, and there was no marked decrease of amplitude. Our data suggest that temporary ischemic changes in the nerve root cause transient conduction disturbances. Pathologic examination showed that the periradicular tissue consisted of the granulation with vascularization and many inflammatory cell infiltrations. The presence of periradicular fibrosis will compound the nerve root pain by fixing the nerve in one position, thereby increasing the susceptibility of the nerve root to tension or compression.

    To determine whether a change in apparent diffusion coefficient (ADC) value could predict early response to CT-guided Oxygen-Ozone (O 2 -O 3 ) injection therapy in patients with unilateral mono-radiculopathy due to lumbar disc herniation. A total of 52 patients with unilateral mono-radiculopathy received a single intradiscal (3 mL) and periganglionic (5 mL) injection of an O 2 -O 3 mixture. An ADC index of the involved side to the intact side was calculated using the following formula: pre-treatment ADC index = ([ADC involved side - ADC intact side] / ADC intact side) x 100. We analyzed the relationship between the pre-treatment Oswestry Disability Index (ODI) and the ADC index. In addition, the correlation between ODI recovery ratio and ADC index was investigated. The sensitivity and specificity of the ADC index for predicting response in O 2 -O 3 therapy was determined. Oswestry Disability Index and the ADC index was not significantly correlated (r = -0.125, p = 0.093). The ADC index and ODI recovery ratio was significantly correlated (r = 0.819, p < 0.001). When using 7.10 as the cut-off value, the ADC index obtained a sensitivity of 86.3% and a specificity of 82.9% for predicting successful response to therapy around the first month of follow-up. This preliminary study demonstrates that the patients with decreased ADC index tend to show poor improvement of clinical symptoms. The ADC index may be a useful indicator to predict early response to CT-guided O 2 -O 3 injection therapy in patients with unilateral mono-radiculopathy due to lumbar disc herniation

    Full Text Available Objective To analyze the causes of surgical complications after treatment of lumbar disc herniation (LDH and lumbar intervertebral foraminal stenosis by percutaneous transforaminal endoscopic discectomy (PTED.  Methods From December 2009 to December 2014, 286 patients with LDH (N = 201 and lumbar intervertebral foraminal stenosis (N = 85 were confirmed by X-ray, CT or MRI and treated by PTED in our hospital. Visual Analogue Scale (VAS was used to evaluate the degree of pain in each paitent before and after operation. The curative effect was evaluated by Macnab score. Surgical complications were recorded to find out the causes and methods to prevent them.  Results All cases were followed up for 3 months, and the VAS score decreased significantly compared with preoperation [1.00 (0.00, 1.05 vs 8.50 (7.75, 9.25; Z = 2.825, P = 0.050]. According to Macnab score, the rate of excellent and good functional recovery was 95.45% (273/286. Procedure-related complications included nerve injury in 8 cases (2.80%, hemorrhage at the operation site and hematoma formation around nerve root in 6 cases (2.10%, rupture of dural sac in one case (0.35%, muscle cramps in 3 cases (1.05%, surgical infection in one case (0.35%, postoperative recurrence in 4 cases (1.40%. All patients with complications were cured after symptomatic treatment. Conclusions The overall effect of percutaneous transforaminal endoscopic discectomy for treating lumbar disc herniation and lumbar intervertebral foraminal stenosis is satisfactory, which has a low incidence rate of postoperative complications. Some tips can effectively reduce the rate of surgical complications such as preoperative evaluation, precise performance, careful hemostasis, shortening the operation time and postoperatively symptomatic treatment, etc. DOI: 10.3969/j.issn.1672-6731.2016.04.007

    Objective: To evaluate the short-term curative effect and the incidence of postoperative adverse events of percutaneous lumbar diskectomy (PLD) combined with ozone or PLD combined with collagenase in treating lumbar disk herniation. Methods: A total of 223 patients with lumbar disk herniation were enrolled in this study. Patients in the study group (n=108) were treated with PLD combined with ozone, while patients in the control group (n=115) were treated with PLD combined with collagenase. The short-term effectiveness and the incidence of postoperative adverse events were documented. The results were analyzed and compared between the two groups. Results: In the study group, the excellent and good therapeutic results were achieved in 85.18% of the patients (n=92) and the occurrence of adverse events was 5.56%, while in the control group, the excellent and good therapeutic results were achieved in 80.00% of the patients (n=92) and the occurrence of adverse events was 13.04%. No significant difference in the short-term effectiveness existed between the two groups (Pearson Chi-Square =1.038, P=0.308). And the difference in the occurrence of postoperative adverse events was not significant between the two groups (Pearson Chi-Square =3.661, P=0.056). No disc infection occurred in the study group. Conclusion: The short-term curative effect of PLD combined with ozone is not significantly different from that of PLD combined with collagenase. In order to maintain decompression within the disc for a long period and to reduce the incidence of postoperative adverse events PLD combined with ozone ablation is an effective complementary treatment.

    Neuropathic pain conditions are common after nerve injuries and are suggested to be regulated in part by genetic factors. We have previously demonstrated a strong genetic influence of the rat major histocompatibility complex on development of neuropathic pain behavior after peripheral nerve injury. In order to study if the corresponding human leukocyte antigen complex (HLA) also influences susceptibility to pain, we performed an association study in patients that had undergone surgery for inguinal hernia (n=189). One group had developed a chronic pain state following the surgical procedure, while the control group had undergone the same type of operation, without any persistent pain. HLA DRB1genotyping revealed a significantly increased proportion of patients in the pain group carrying DRB1*04 compared to patients in the pain-free group. Additional typing of the DQB1 gene further strengthened the association; carriers of the DQB1*03:02 allele together with DRB1*04 displayed an increased risk of postsurgery pain with an odds risk of 3.16 (1.61-6.22) compared to noncarriers. This finding was subsequently replicated in the clinical material of patients with lumbar disc herniation (n=258), where carriers of the DQB1*03:02 allele displayed a slower recovery and increased pain. In conclusion, we here for the first time demonstrate that there is an HLA-dependent risk of developing pain after surgery or lumbar disc herniation; mediated by the DRB1*04 - DQB1*03:02 haplotype. Further experimental and clinical studies are needed to fine-map the HLA effect and to address underlying mechanisms. Copyright © 2012 International Association for the Study of Pain.

    2006-01-01

    Purpose: To study the location of (Modic) MR signal alterations (SA) of the cartilage endplate (CEP) in pre- and non-operated segments L3-S1 with special focus on the presence of recurrent lumbar disc herniation (RLDH). Materials and Methods: In a retrospective study the MR images of vertebrae L3-S1 of 65 consecutive patients with a history of microdiscectomy were evaluated. Of the 190 segments studied, 67 were pre-operated. These were divided into a group with recurrent lumbar disc herniation (RLDH) (n=19) and a group without evidence of RLDH (n=48). Non-operated segments (n=123) were also considered as a separate group. In these three groups the prevalence of different Modic types was determined using the sag. T1- and T2-weighted images, and, in particular, the distribution of SA at the upper and lower CEP was examined by evaluating the sag. T2-weighted images. In order to achieve this, each CEP was divided into nine regions. Results: Pre-operated segments showed significantly more frequent (p<0.001) and more expansive (p<0.001) SA than non-operated segments. Non-operated segments showed SA less frequently in the central region of both upper and lower CEP (p=0.056 and p=0.015, respectively). In operated segments without RLDH, the upper CEP had significantly more SA on the operation side than in the mid-sagittal and contra-lateral regions (p=0.016, p=0.037) and significantly more on the operation side of the lower CEP than in the contra-lateral region (p=0.027). Operated segments with RLDH did not show an emphasis of SA on the operation side. In this group SA occurred significantly more often in the central and ventral mid-sagittal regions of the upper CEP than in the preoperated segments without RLDH. (orig.)

  14. Outcome of physiotherapy after surgery for cervical disc disease: a prospective randomised multi-centre trial

    2014-01-01

    Background Many patients with cervical disc disease require leave from work, due to long-lasting, complex symptoms, including chronic pain and reduced levels of physical and psychological function. Surgery on a few segmental levels might be expected to resolve disc-specific pain and reduce neurological deficits, but not the non-specific neck pain and the frequent illness. No study has investigated whether post-surgery physiotherapy might improve the outcome of surgery. The main purpose of this study was to evaluate whether a well-structured rehabilitation programme might add benefit to the customary post-surgical treatment for cervical disc disease, with respect to function, disability, work capability, and cost effectiveness. Methods/Design This study was designed as a prospective, randomised, controlled, multi-centre study. An independent, blinded investigator will compare two alternatives of rehabilitation. We will include 200 patients of working age, with cervical disc disease confirmed by clinical findings and symptoms of cervical nerve root compression. After providing informed consent, study participants will be randomised to one of two alternative physiotherapy regimes; (A) customary treatment (information and advice on a specialist clinic); or (B) customary treatment plus active physiotherapy. Physiotherapy will follow a standardised, structured programme of neck-specific exercises combined with a behavioural approach. All patients will be evaluated both clinically and subjectively (with questionnaires) before surgery and at 6 weeks, 3 months, 6 months, 12 months, and 24 months after surgery. The main outcome variable will be neck-specific disability. Cost-effectiveness will also be calculated. Discussion We anticipate that the results of this study will provide evidence to support physiotherapeutic rehabilitation applied after surgery for cervical radiculopathy due to cervical disc disease.

    1999-01-01

    Purpose: We examined the postoperative changes of the cervical spine after treatment of cervical nerve root compression with anterior cervical discectomy and fusion with a new titanium intervertebral disc. Patients and Methods: 37 patients were examined prior to, as well as 4 days, 6 weeks, and 7 months after surgery. Lateral view X-rays and functional imaging were used to evaluate posture and mobility of the cervical spine, the position of the implants, and the reactions of adjacent bone structures. Results: Implantation of the titanium disc led to post-operative distraction of the intervertebral space and slight lordosis. Within the first 6 months a slight loss of distraction and re-kyphosis due to impression of the implants into the vertebral end-plates were found in all patients. We noted partial infractions into the vertebral end-plates in 10/42 segments and slight mobility of the implants in 14/42 segments. Both groups of patients showed reactive spondylosis and local symptoms due to loosening of the implants. The pain subsided after onset of bone bridging and stable fixation of the loosened discs. Conclusions: The titanium intervertebral disc provides initial distraction of the fusioned segments with partial recurrence of kyphosis during the subsequent course. Loosening of the implants with local symptoms can be evaluated with follow-up X-rays and functional imaging. (orig.) [de

    Cross-sectional survey. The objective of this study was to investigate the authorship, content, and quality of information available to the public on the Internet pertaining to the cervical artificial disc replacement device. The Internet is widely used by patients as an educational tool for health care information. In addition, the Internet is used as a medium for direct-to-consumer marketing. Increasing interest in cervical artificial disc replacement has led to the emergence of numerous Web sites offering information about this procedure. It is thought that patients can be influenced by information found on the Internet. A cross section of Web sites accessible to the general public was surveyed. Three commonly used search engines were used to locate 150 (50/search engine) Web sites providing information about the cervical artificial disc replacement. Each Web site was evaluated with regard to authorship and content. Fifty-three percent of the Web sites reviewed were authorized by a private physician group, 4% by an academic physician group, 13% by industry, 16% were news reports, and 14% were not otherwise categorized. Sixty-five percent of Web sites offered a mechanism for direct contact and 19% provided clear patient eligibility criteria. Benefits were expressed in 80% of Web sites, whereas associated risks were described in 35% or less. European experiences were noted in 17% of Web sites, whereas only 9% of Web sites detailed the current US experience. CONCLUSION.: The results of this study demonstrate that much of the content of the Internet-derived information pertaining to the cervical artificial disc replacement is for marketing purposes and may not represent unbiased information. Until we can confirm the content on a Web site to be accurate, patients should be cautioned when using the Internet as a source for health care information related to cervical disc replacement.

Preoperative CT and MRI were analyzed, which were based on the main location of the herniated disc and its relationship with compressed nerve root. Sixty-two patients satisfied the inclusion criteria during the period from August 2012 to March 2014. We use percutaneous full-endoscopic discectomy through different puncture technique to remove the protrusive NP for LDH. Sixty patients completed the full-endoscopic operation successfully. Their removed disc tissue volume ranged from 1.5 mL to 3.8 mL each time. Postoperative ODI and VAS of low back and sciatica pain were significantly decreased in each time point compared to preoperative ones. No nerve root injury, infection, and other complications occurred. The other two patients were shifted to open surgery. No secondary surgery was required and 91.6% of excellent-to-good ratio was achieved on the basis of Macnab criteria at postoperative 12 months. Acquired benefits are fewer complications, rapid recovery, complete NP removal, effective nerve root decompression, and satisfactory cosmetic effect as well. This is a safe, effective, and rational minimally invasive spine-surgical technology with excellent clinical outcome.

    Our objective was to use an open weight-bearing MRI to identify the effects of different loading conditions on the inter-vertebral anatomy of the lumbar spine in a post-discectomy recurrent lumbar disc herniation patient. A 43-year-old male with a left-sided L5-S1 post-decompression re-herniation underwent MR imaging in three spine-loading conditions: (1) supine, (2) weight-bearing on standing (WB), and (3) WB with 10 % of body mass axial loading (WB + AL) (5 % through each shoulder). A segmentation-based proprietary software was used to calculate and compare linear dimensions, angles and cross sections across the lumbar spine. The L5 vertebrae showed a 4.6 mm posterior shift at L5-S1 in the supine position that changed to an anterior translation >2.0 mm on WB. The spinal canal sagittal thickness at L5-S1 reduced from supine to WB and WB + AL (13.4, 10.6, 9.5 mm) with corresponding increases of 2.4 and 3.5 mm in the L5-S1 disc protrusion with WB and WB + AL, respectively. Change from supine to WB and WB + AL altered the L5-S1 disc heights (10.2, 8.6, 7.0 mm), left L5-S1 foramen heights (12.9, 11.8, 10.9 mm), L5-S1 segmental angles (10.3°, 2.8°, 4.3°), sacral angles (38.5°, 38.3°, 40.3°), L1-L3-L5 angles (161.4°, 157.1°, 155.1°), and the dural sac cross sectional areas (149, 130, 131 mm 2 ). Notably, the adjacent L4-L5 segment demonstrated a retro-listhesis >2.3 mm on WB. We observed that with weight-bearing, measurements indicative of spinal canal narrowing could be detected. These findings suggest that further research is warranted to determine the potential utility of weight-bearing MRI in clinical decision-making.

    A total of 210 cervical intervertebral discs were taken at autopsy from 36 cadavers, and underwent both magnetic resonance imaging (MRI) and discography to compare their diagnostic efficacies for investigating degenerative changes in the cervical spine. The age of the subjects had ranged from 43 to 92 years with an average of 68.1 years. Following the autopsy, MRI and discography were performed on the excised cervical spinal column, and the specimen was then prepared for histological examination. The findings were compared with those of the lumbar spine that had previously been reported by Yasuma et al. on 1238 lumbar discs from 197 cadavers ranging in age from 11 to 92 years. The results were as follows: Low intensity in the T2-weighted MRI was well correlated with histological degeneration in the cervical disc. The rate of appearance of the posterior protrusion of the cervical disc on the MRI was in accordance with the degree of histological disc degeneration, but it did not always correspond with histological posterior protrusion. There was a remarkably high incidence for false-positive posterior protrusion on the MRI, which should be kept in mind on reading the MRI. In the comparison of the MRI with the discography, a certain positive correlation was found as for disc degeneration, but not in complete accordance. There was a considerable difference in the patterns of degeneration and in posterior protrusion of the discs between the cervical spine and the lumbar spine. The posterior protrusion in the cervical disc was more likely related to horizontal fissure and hyalinization of the posterior annulus, while posterior protrusion in the lumbar disc was often related to reversed orientation of the bundles and myxomatous degeneration of the posterior annulus. This difference was attributed to the difference in the mechanical properties of the cervical and lumbar spines. (author).

    To study the influence of (Modic) signal alterations (SA) of the cartilage endplate (CEP) of vertebrae L3-S1 on the outcome of an in-patient minimally invasive treatment (MIT) using epidural injections on patients with lumbar disc herniation (LDH). The MR images of 59 consecutive patients with LDH within segments L3/L4 - L5/S1 undergoing in-patient minimally invasive treatment with epidural injections were evaluated in a clinical study. The (Modic) signal alterations of the CEP were recorded using T1- and T2-weighted sagittal images. On the basis of the T2-weighted sagittal images, the extension and distribution of the SA were measured by dividing each CEP into 9 areas. The outcome of the MIT was recorded using the Oswestry Disability Index (ODI) before and after therapy and in a 3-month follow-up. Within a subgroup of patients (n = 35), the distribution and extension of the signal alterations were correlated with the development of the ODI. Segments with LDH showed significantly more (p < 0.001) SA of the CEP than segments without LDH. Although the extension of the SA was not dependent on sex, it did increase significantly with age (p = 0.017). The outcome after MIT did not depend on the sex and age of the patients nor on the type of LDH. The SA extension tended to have a negative correlation with the outcome after MIT after 3 months (p = 0.071). A significant negative correlation could be established between the SA extension in the central section of the upper endplate and the outcome after 3 months (p = 0.019). 1. Lumbar disc herniation is clearly associated with the prevalence of (Modic) signal alterations. 2. Extensive signal alterations tend to correlate with a negative outcome of an MIT using epidural injections. 3. Such SA in the central portion of the upper CEP correlate significantly with a negative treatment result. 4. The central portion of the upper CEP being extensively affected by (Modic) SA is a negative predictor for the success of a minimally

    The objective was to assess the effects of therapeutic nuclear magnetic resonance (tNMR) as a conservative treatment for lumbar radicular syndrome (LRS) in patients with lumbar disc herniation. The prospective, randomised, double-blind, placebo-controlled trial included 94 patients, aged 20-60 years (44.79 ± 8.83), with LRS caused by lumbar disc herniation confirmed by MRI scans and with clinical signs of a radicular lesion without indication for surgical intervention. Treatment group (TG) and control group (CG) received standard non-surgical therapy. Additionally, the TG had seven sessions with the tNMR device with a magnetic flux density of 2.3 mT and a frequency of 85 kHz; the CG received 7 sham treatments. Outcome parameters were the treatment effect on pain intensity (Visual Analogue Scale-VAS), health-related quality of life (36-item Short Form Health Survey-SF-36), disease-related disability (Roland Morris Disability Questionnaire-RMDQ), pain medication intake, duration of sick leave and morphological changes assessed by MRI scan analysis. VAS scores improved significantly in both groups (p Patients in the TG recorded significantly fewer days of sick leave in month 3 after treatment (p = 0.026). MRI scan summary scores improved significantly in both groups (L4/5 p treatment of lumbar disc herniation with LRS. The application of tNMR did not meet MCID criteria. It rendered few statistically significant differences between patient groups. The overall results of this trial make a clinical implementation of tNMR in the treatment of lumbar disc herniation with LRS appear premature. Further research is needed to better understand the mode of action of tNMR on compressed neural tissue and to elucidate the issue of the cost/benefit ratio.

    2014-08-01

    Current health care reform calls for a reduction of procedures and treatments that are less effective, more costly, and of little value (high cost/low quality). The authors assessed the 2-year cost and effectiveness of comprehensive medical management for lumbar spondylolisthesis, stenosis, and herniation by utilizing a prospective single-center multidisciplinary spine center registry in a real-world practice setting. Analysis was performed on a prospective longitudinal quality of life spine registry. Patients with lumbar spondylolisthesis (n = 50), stenosis (n = 50), and disc herniation (n = 50) who had symptoms persisting after 6 weeks of medical management and who were eligible for surgical treatment were entered into a prospective registry after deciding on nonsurgical treatment. In all cases, comprehensive medical management included spinal steroid injections, physical therapy, muscle relaxants, antiinflammatory medication, and narcotic oral agents. Two-year patient-reported outcomes, back-related medical resource utilization, and occupational work-day losses were prospectively collected and used to calculate Medicare fee-based direct and indirect costs from the payer and societal perspectives. The maximum health gain associated with medical management was defined as the improvement in pain, disability, and quality of life experienced after 2 years of medical treatment or at the time a patient decided to cross over to surgery. The maximum health gain in back pain, leg pain, disability, quality of life, depression, and general health state did not achieve statistical significance by 2 years of medical management, except for pain and disability in patients with disc herniation and back pain in patients with lumbar stenosis. Eighteen patients (36%) with spondylolisthesis, 11 (22%) with stenosis, and 17 (34%) with disc herniation eventually required surgical management due to lack of improvement. The 2-year improvement did not achieve a minimum clinically

    To evaluate the long-term effects of postoperative comprehensive physiotherapy starting one week after lumbar disc surgery. Twelve-year follow-up of a three-armed, randomized, controlled, single-blinded clinical trial. Department of Physical Medicine & Rehabilitation. Of 111 patients following first-time, uncomplicated lumbar disc surgery who participated in the original study and completed the treatment originally allocated, 74 ((67%; 29 (73%) physiotherapy, 22 (58%) sham therapy, 23 (68%) no therapy) completed a 12-year follow-up examination. In the original study, patients had been randomly assigned to comprehensive physiotherapy, sham intervention (neck massage), or no therapy. Low Back Pain Rating Scale; best score 0, worst score 130 points). At 12 years after surgery, the group participating in comprehensive physiotherapy had significantly better functional outcomes, as rated on the Low Back Pain Rating Score, than the untreated group (mean difference: -13.2 (95% CI: (-25.4; -1.0)). Equally, there was a clinically relevant, non-significant difference between the sham therapy and no therapy (mean difference: -12.5 (95%CI: -26.1; 1.1)). Consequently, the Low Back Pain Rating Score outcome did not differ between physiotherapy and sham therapy (mean difference: -0.7 (95%CI: -14.2; 12.8)). Participating in a comprehensive physiotherapy program following lumbar disc surgery may be associated with better long-term health benefits over no intervention, but may not be superior to sham therapy. © The Author(s) 2014.

    Background The design of a randomized multicenter trial is presented on the effectiveness of a prolonged conservative treatment strategy compared with surgery in patients with persisting intense sciatica (lumbosacral radicular syndrome). Methods/design Patients presenting themselves to their general practitioner with disabling sciatica lasting less than twelve weeks are referred to the neurology outpatient department of one of the participating hospitals. After confirmation of the diagnosis and surgical indication MRI scanning is performed. If a distinct disc herniation is discerned which in addition covers the clinically expected site the patient is eligible for randomization. Depending on the outcome of the randomization scheme the patient will either be submitted to prolonged conservative care or surgery. Surgery will be carried out according to the guidelines and between six and twelve weeks after onset of complaints. The experimental therapy consists of a prolonged conservative treatment under supervision of the general practitioner, which may be followed by surgical intervention in case of persisting or progressive disability. The main primary outcome measure is the disease specific disability of daily functioning. Other primary outcome measures are perceived recovery and intensity of legpain. Secondary outcome measures encompass severity of complaints, quality of life, medical consumption, absenteeism, costs and preference. The main research question will be answered at 12 months after randomization. The total follow-up period covers two years. Discussion Evidence is lacking concerning the optimal treatment of lumbar disc induced sciatica. This pragmatic randomized trial, focusses on the 'timing' of intervention, and will contribute to the decision of the general practictioner and neurologist, regarding referral of patients for surgery.

    To observe the efficacy of acupuncture stimulation of the sciatic nerve trunk in the treatment of patients suffering from sciatica induced by lumbar disc herniation (LDH). A total of 60 LDH sciatica patients met the inclusion criteria were randomly divided into treatment group and control group, with 30 cases in each. Patients of the treatment group were treated by directly needling the sciatic nerve and routine acupuncture of Ashi -points, Lumbar Jiaji (EX-B 2), Dachangshu (BL 28), etc., and those of the control group treated by simple routine acupuncture. The treatment was conducted once a day, 5 times a week, 4 weeks altogether. The clinical effect was evaluated according to the "Standards for Diagnosis and Therapeutic Effect Evaluation of Syndromes of Chinese Medicine" and the pain intensity was assessed by using simplified Short-Form McGill Pain Questionnaire (SF-MPQ) containing pain rating index (PRI), visual analogue scale (VAS) and present pain intensity (PPI). After the treatment, of the two 30 cases of LDH sciatica patients in the control and treatment groups, 11 and 18 were cured, 7 and 7 experienced marked improvement, 10 and 4 were effective, 2 and 1 was invalid, with the effective rate being 93.3% and 96.7%, respectively. The cured+markedly effective rate of the treatment group was significantly higher than that of the control group ( P sciatica in LDH patients, and is superior to simple routine acupuncture in the clinical efficacy.

    Lumbar discectomy is among the most frequently performed procedures in spinal surgery. Transforaminal percutaneous endoscopic discectomy (TPED) is a minimally invasive technique that gains ground among surgeons in the recent years. TPED has been studied in terms of effectiveness, however little is known about its overall impact on health-related quality of life (HRQoL) of the patients. To investigate the progress of HRQoL following TPED. Seventy-six (76) patients were enrolled in the study. Mean age was 56.5 ±12.1 years with 38 (50%) males and 38 (50%) females. All patients underwent TPED at L3-L4 (27.6%), L4-L5 (52.6%) and L5-S1 (19.7%). SF-36 was used for the assessment of HRQoL preoperatively and at 6 weeks, at 3, 6 and 12 months after the procedure. All aspects of SF-36 questionnaire showed statistically significant improvement one year after the procedure (p< 0.001). Role limitations due to physical problems, bodily pain and role limitations due emotional problems showed the highest improvement, followed by physical functioning, vitality, social functioning, mental health and general health. TPED for lumbar disc herniation is associated with significant improvement in all aspects of health-related quality of life within 6 weeks postoperatively and the improvement remains significant one year after surgery, as measured by the SF-36 questionnaire.

    2017-08-01

    Pain drawings have been frequently used in the preoperative evaluation of spine patients. For lumbar conditions comprehensive research has established both the reliability and predictive value, but for the cervical spine most of this knowledge is lacking. The aims of this study were to validate pain drawings for the cervical spine, and to investigate the predictive value for treatment outcome of four different evaluation methods. We carried out a post hoc analysis of a randomized controlled trial, comparing cervical disc replacement to fusion for radiculopathy related to degenerative disc disease. A pain drawing together with Neck Disability Index (NDI) was completed preoperatively, after 2 and 5 years. The inter- and intraobserver reliability of four evaluation methods was tested using κ statistics, and its predictive value investigated by correlation to change in NDI. Included were 151 patients, mean age of 47 years, female/male: 78/73. The interobserver reliability was fair for the modified Ransford and Udén methods, good for the Gatchel method, and very good for the modified Ohnmeiss method. Markings in the shoulder and upper arm region on the pain drawing were positive predictors of outcome after 2 years of follow-up, and markings in the upper arm region remained a positive predictor of outcome even after 5 years of follow-up. Pain drawings were a reliable tool to interpret patients' pain prior to cervical spine surgery and were also to some extent predictive for treatment outcome.

    Full Text Available Objective is to describe a safe and effective percutaneous endoscopic approach for removal of highly migrated and sequestrated disc herniations of the upper lumbar spine and to report the results, surgical indications, and technical considerations of the new technique. Eleven patients who had highly migrated and sequestrated disc herniations in the upper lumbar were included in this study. A retrospective study was performed for all patients after translaminar osseous channel-assisted PELD was performed. Radiologic findings were investigated, and pre-and postoperative visual analog scale (VAS assessments for back and leg pain and Oswestry disability index (ODI evaluations were performed. Surgical outcomes were evaluated under modified MacNab criteria. All of the patients were followed for more than 1 year. The preoperative and postoperative radiologic findings revealed that the decompression of the herniated nucleus pulposus (HNP was complete. After surgery, the mean VAS scores for back and leg pain immediately improved from 8.64 (range, 7–10 and 8.00 (range, 6–10 to 2.91 (range, 2–4 and 2.27 (range, 1–3, respectively. The mean preoperative ODI was 65.58 (range, 52.2–86, which decreased to 7.51 (range, 1.8–18 at the 12-month postoperative follow-up. The MacNab scores at the final follow-up included nine excellent, one good, and one fair. The modified translaminar osseous channel-assisted PELD could be a safe and effective option for the treatment of highly migrated and sequestrated disc herniations of the upper lumbar.

    The purpose of this study was to evaluate whether specific MRI features, such as axial location and type of herniation, are associated with outcomes of symptomatic lumbar disc herniation patients treated with spinal manipulation therapy (SMT). MRI and treatment outcome data from 68 patients were included in this prospective outcomes study. Pain numerical rating scale (NRS) and Oswestry physical disability questionnaire (OPDQ) levels were measured at baseline. The Patients Global Impression of Change scale, the NRS and the OPDQ were collected at 2 weeks, 1, 3, 6 months and 1 year. One radiologist and 2 chiropractic medicine master's degree students analyzed the MRI scans blinded to treatment outcomes. κ statistics assessed inter-rater reliability of MRI diagnosis. The proportion of patients reporting relevant improvement at each time point was compared based on MRI findings using the chi-square test. The t test and ANOVA compared the NRS and OPDQ change scores between patients with various MRI abnormalities. A higher proportion of patients with disc sequestration reported relevant improvement at each time point but this did not quite reach statistical significance. Patients with disc sequestration had significantly higher reduction in leg pain at 1 month compared to those with extrusion (P = .02). Reliability of MRI diagnosis ranged from substantial to perfect (K = .733-1.0). Patients with sequestered herniations treated with SMT to the level of herniation reported significantly higher levels of leg pain reduction at 1 month and a higher proportion reported improvement at all data collection time points but this did not reach statistical significance.

    Background The ideal surgical approach for cervical disk disease remains controversial, especially for multilevel cervical disease. The purpose of this study was to investigate the biomechanics of the cervical spine after 3-level hybrid surgery compared with 3-level anterior cervical discectomy and fusion (ACDF). Material/Methods Eighteen human cadaveric spines (C2-T1) were evaluated under displacement-input protocol. After intact testing, a simulated hybrid construct or fusion construct was created between C3 to C6 and tested in the following 3 conditions: 3-level disc plate disc (3DPD), 3-level plate disc plate (3PDP), and 3-level plate (3P). Results Compared to intact, almost 65~80% of motion was successfully restricted at C3-C6 fusion levels (p0.05). 3PDP construct resulted in significant decrease of ROM at C3-C6 levels less than 3P (pbiomechanical advantages compared to fusion in normalizing motion.

    The purpose of this study was to evaluate the effects of psychosocial factors on pain levels and depression, before and after surgical treatment, in patients with degenerative lumbar and cervical vertebral disc disease. The study included 188 patients (98 women, 90 men) who were confirmed to have cervical or lumbar degenerative disc disease on magnetic resonance imaging, and who underwent a single microdiscectomy procedure, with no postoperative surgical complications. All patients completed two questionnaires before and after surgery - the Beck Depression Inventory scale (I-IV) and the Visual Analog Scale for pain (0-10). On hospital admission, all patients completed a social and demographic questionnaire. The first pain and depression questionnaire evaluations were performed on the day of hospital admission (n=188); the second on the day of hospital discharge, 7 days after surgery (n=188); and the third was 6 months after surgery (n=140). Patient ages ranged from 22 to 72 years, and 140 patients had lumbar disc disease (mean age, 42.7±10.99 years) and 44 had cervical disc disease (mean age, 48.9±7.85 years). Before surgery, symptoms of depression were present in 47.3% of the patients (11.7% cervical; 35.6% lumbar), at first postoperative evaluation in 25.1% of patients (7% cervical; 18.1% lumbar), and 6 months following surgery in 31.1% of patients (7.5% cervical; 23.6% lumbar). Patients with cervical disc disease who were unemployed had the highest incidence of depression before and after surgery ( p =0.037). Patients with lumbar disc disease who had a primary level of education or work involving standing had the highest incidence of depression before and after surgery ( p =0.368). This study highlighted the association between social and demographic factors, pain perception, and depression that may persist despite surgical treatment for degenerative vertebral disc disease.

    Until quite recently spinal disorder problems in the U.S. have been operated by fusing cervical vertebrae instead of replacement of the cervical disc with an artificial disc. Cervical disc replacement is a recently approved procedure in the U.S. It is one of the most challenging surgical procedures in the medical field due to the deficiencies in available diagnostic tools and insufficient number of surgical practices For physicians and surgical instrument developers, it is critical to understand how to successfully deploy the new artificial disc replacement systems. Without proper understanding and practice of the deployment procedure, it is possible to injure the vertebral body. Mixed reality (MR) and virtual reality (VR) surgical simulators are becoming an indispensable part of physicians' training, since they offer a risk free training environment. In this study, MR simulation framework and intricacies involved in the development of a MR simulator for the rasping procedure in artificial cervical disc replacement (ACDR) surgery are investigated. The major components that make up the MR surgical simulator with motion tracking system are addressed. A mixed reality surgical simulator that targets rasping procedure in the artificial cervical disc replacement surgery with a VICON motion tracking system was developed. There were several challenges in the development of MR surgical simulator. First, the assembly of different hardware components for surgical simulation development that involves knowledge and application of interdisciplinary fields such as signal processing, computer vision and graphics, along with the design and placements of sensors etc . Second challenge was the creation of a physically correct model of the rasping procedure in order to attain critical forces. This challenge was handled with finite element modeling. The third challenge was minimization of error in mapping movements of an actor in real model to a virtual model in a process called

    2010-01-01

    To summarize the recent minimally invasive approach for cervical spondylotic radiculopathy (CSR). The recent literature at home and abroad concerning minimally invasive approach for CSR was reviewed and summarized. There were two techniques of minimally invasive approach for CSR at present: percutaneous puncture techniques and endoscopic techniques. The degenerate intervertebral disc was resected or nucleolysis by percutaneous puncture technique if CSR was caused by mild or moderate intervertebral disc herniations. The cervical microendoscopic discectomy and foraminotomy was an effective minimally invasive approach which could provide a clear view. The endoscopy techniques were suitable to treat CSR caused by foraminal osteophytes, lateral disc herniations, local ligamentum flavum thickening and spondylotic foraminal stenosis. The minimally invasive procedure has the advantages of simple handling, minimally invasive and low incidence of complications. But the scope of indications is relatively narrow at present.

    To understand whether a spondylolisthesis in the sub-axial spine cranial to a cervical disc arthroplasty (CDA) construes a risk of adjacent level disease (ALD). A retrospective review of 164 patients with a minimum 5-year follow-up of a cervical disc arthroplasty was performed. Multi-level surgeries, including hybrid procedures, were included. Multiple implant types were included. The two inter-vertebral discs (IVD) cranial of the CDA were monitored for evidence of radiologic degeneration using the Kettler criteria. The rate of ALD in CDA found in this series was 17.8%, with most affecting the immediately adjacent IVD (27.4 and 7.6%, respectively p = 0.000). Pre-operative mild spondylolisthesis adjacent to a planned CDA was not found to be a risk factor for ALD within 5 years. Those with a degenerative spondylolisthesis are at higher risk of ALD (33%) than those with a non-degenerative cause for their spondylolisthesis (11%). Post-operative CDA alignment, ROM or induced spondylolisthesis do not affect the rate of ALD in those with an adjacent spondylolisthesis. Patients with ALD experience significantly worse 5-year pain and functional outcomes than those unaffected by ALD. A pre-operatively identified mild spondylolisthesis in the sub-axial spine cranially adjacent to a planned CDA is not a risk factor for ALD within 5 years.

  2. Cervical spine degenerative changes (narrowed intervertebral disc spaces and osteophytes) in coal miners

    Zejda, J. E.; Stasiow, B.

    2003-01-01

    A series of 685 x-rays films of the cervical spine obtained in coal miners was analyzed to explore the occurrence of narrowed disc spaces and osteophytes in this occupational group, and to examine the association of x-rays changes with age, duration of employment, and duration of occupational exposure to hand-arm vibration. All data were extracted from individual medical files of coal miners examined for suspected hand-arm vibration-related disorders in 1989-1999 at the Occupational Medicine Center in Katowice. The narrowed intervertebral disc spaces were found in 188 coal miners (26.9%) and osteophytes in 332 coal miners (47.5%). The occurrence of degenerative changes in coal miners was similar to that observed in a small group of 68 blue-collar workers (no exposure to hand-arm vibration) employed in the coal industry. Univariate comparisons showed that intervertebral disc spaces and osteophytes were more frequent among older subjects and among subjects with longer duration of employment. The results of logistic regression analysis confirmed statistically significant effect of age, but not of other factors included in the model. When both x-ray changes were grouped together (a combined dependent variable) age remained the only statistically significant explanatory variable. The findings do not support the view that the examined degenerative changes in cervical spine are more prevalent in coal miners and depend on duration of physical work or local exposure to hand-arm vibration in this occupational group.

    We wanted to investigate the relationship between the magnetic resonance (MR) findings and the clinical outcome after treatment with non-surgical transforaminal epidural steroid injections (ESI) for lumbar herniated intervertebral disc (HIVD) patients. Transforaminal ESI were performed in 91 patients (50 males and 41 females, age range: 13 78 yrs) because of lumbosacral HIVD from March 2001 to August 2002. Sixty eight patients whose MRIs and clinical follow-ups were available were included in this study. The medical charts were retrospectively reviewed and the patients were divided into two groups; the successful (responders, n = 41) and unsatisfactory (non-responders, n = 27) outcome groups. A successful outcome required a patient satisfaction score greater than two and a pain reduction score greater than 50%. The MR findings were retrospectively analyzed and compared between the two groups with regard to the type (protrusion, extrusion or sequestration), hydration (the T2 signal intensity), location (central, right/left central, subarticular, foraminal or extraforaminal), and size (volume) of the HIVD, the grade of nerve root compression (grade 1 abutment, 2 displacement and 3 entrapment), and an association with spinal stenosis. There was no significant difference between the responders and nonresponders in terms of the type, hydration and size of the HIVD, or an association with spinal stenosis (p > 0.05). However, the location of the HIVD and the grade of nerve root compression were different between the two groups (p < 0.05). MRI could play an important role in predicting the clinical outcome of non-surgical transforaminal ESI treatment for patients with lumbar HIVD

    Percutaneous transforaminal endoscopic discectomy (PTED) is a minimally invasive surgical technique used principally for the treatment of lumbar disc herniation (LDH). LDH is a frequent spinal ailment in obese individuals. The aim of this prospectively designed study was to assess for the first time in the literature the impact of PTED in postoperative parameters of health-related quality of life (HRQoL) in obese patients with LDH within a 2-year follow-up period, to further evaluate the effectiveness of PTED. Patients with surgically treatable LDH were divided into 2 groups. Group A constituted 20 obese patients, and group B was composed of 10 patients with normal body mass index (BMI). A visual analog scale was used for pain evaluation, and the Short Form SF-36 Medical Survey Questionnaire contributed to HRQoL assessment. Follow-up was conducted preoperatively and at 6 weeks and 3, 6, 12, and 24 months postoperatively. Two of the 20 patients (10%) presented with severe postoperative pain, necessitating conventional microdiscectomy. All studied parameters exhibited maximal improvement at 6 months in group A and at 6 weeks in group B, with subsequent stabilization. Obese patients scored lower in all parameters compared with their healthy counterparts with normal BMI, acquiring a less favorable clinical benefit. PTED appears to be a generally safe and effective method for treating obese patients with LDH. However, major technical challenges that lead to a higher frequency of complications, as well as the lesser acquired clinical benefit, in obese patients may contribute to the further consideration for PTED in specific obese patients, especially on the grounds of low surgical experience.

    Purpose: To study the influence of (Modic) signal alterations (SA) of the cartilage endplate (CEP) of vertebrae L3-S1 on the outcome of an in-patient minimally invasive treatment (MIT), using epidural injections on patients with lumbar disc herniation (LDH). Materials and Methods: The MR images of 59 consecutive patients with LDH within segments L3/L4-L5/S1 undergoing in-patient minimally invasive treatment with epidural injections were evaluated in a clinical study. The (Modic) signal alterations of the CEP were recorded using T1- and T2-weighted sagittal images. On the basis of the T2-weighted sagittal images, the extension and distribution of the SA were measured by dividing each CEP into 9 areas. The outcome of the MIT was recorded using the Oswestry Disability Index (ODI) before and after therapy and in a 3-month follow-up. Within a subgroup of patients (n=35), the distribution and extension of the signal alterations were correlated with the development of the ODI. Results: Segments with LDH showed significantly more (p<0.001) SA of the CEP than segments without LDH. Although the extension of the SA was not dependent on sex, it did increase significantly with age (p=0.017). The outcome after MIT did not depend on the sex and age of the patients or on the type od LDH. The SA extension tended to have a negative correlation with the outcome after MIT after 3 months (p=0.071). A significant negative correlation could be established between the SA extension in the central section of the upper endplate and the outcome after 3 months (p=0.019). (orig.)

    Hodgkin's disease may involve the spine as a setting of the advanced disease. An initial manifestation of Hodgkin's disease in spine is extremely rare and the major involved sites usually are the thoracic or cervical spine. The mechanisms of pathogenesis for the formation of an epidural mass during Hodgkin's disease are hematogenous dissemination from nodal sites or local infiltration of lymphomatous tissue. We document here a case of a 16 year-old boy who suffered from incomplete voiding due to dumbbell-shaped retroperitoneal Hodgkin's disease with cauda equina compression. He was successfully managed using surgery and adjuvant chemotherapy. Although lymphadenomatous tissue responds well to radiotherapy and chemotherapy, the role of surgery in this case was to achieve immediate nerve tissue decompression and to obtain an adequate specimen for pathological diagnosis. Magnetic resonance imaging (MRI) is a non-invasive and helpful tool when detecting spinal and paraspinal lesions and we emphasize that spinal MRI should be performed without delay if there is persistent back pain or sciatica.

    Cervical total disc replacement (CTDR) was developed to treat cervical spondylosis, while preserving motion. While anterior cervical discectomy and fusion (ACDF) has been the standard of care for 2-level disease, a randomized clinical trial (RCT) suggested similar outcomes. Cost-effectiveness of this intervention has never been elucidated. To determine the cost-effectiveness of CTDR compared with ACDF. Data were derived from an RCT that followed up 330 patients over 24 months. The original RCT consisted of multi-institutional data including private and academic institutions. Using linear regression for the current study, health states were constructed based on the stratification of the Neck Disability Index and a visual analog scale. Data from the 12-item Short-Form Health Survey questionnaires were transformed into utilities values using the SF-6D mapping algorithm. Costs were calculated by extracting Diagnosis-Related Group codes from institutional billing data and then applying 2012 Medicare reimbursement rates. The costs of complications and return-to-work data were also calculated. A Markov model was built to evaluate quality-adjusted life-years (QALYs) for both treatment groups. The model adopted a third-party payer perspective and applied a 3% annual discount rate. Patients included in the original RCT had to be diagnosed as having radiculopathy or myeloradiculopathy at 2 contiguous levels from C3-C7 that was unresponsive to conservative treatment for at least 6 weeks or demonstrated progressive symptoms. Incremental cost-effectiveness ratio of CTDR compared with ACDF. A strong correlation (R2 = 0.6864; P sensitivity analysis, the incremental cost-effectiveness ratio value stays below the threshold of $50,000 per QALY in most scenarios (range, -$58,194 to $147,862 per QALY). The incremental cost-effectiveness ratio of CTDR compared with traditional ACDF is lower than the commonly accepted threshold of $50,000 per QALY. This remains true with varying input

  9. Calcification of intervertebral discs in children

    Hoermann, D.

    1984-01-01

    Thirteen children with intervertebral disc calcifications of the cervical, thoracal and lumbar spine have been diagnosed since 1970. Most of them were observed over a period of several years. Ten children fell ill with acute pains, but only 2 of them sufferred from a trauma. In 3 cases the features were discovered accidentally combined with malformations of vertebral bodies and congenital diseases. Our results suggest a primary structural inferiority of the calcified discs. The calcifications arise partially from a birth trauma, partially from an unknown etiology. They can last for a long time without symptoms. An acute event effects the pains due to shifting or herniation of calcified disc-fragments. Secondary findings such as decrease of the height of cervical vertebral bodies or destructions of the endplates of thoracal and lumbar vertebral bodies disappear retarded and often incompletely and demand a control for a long time.

    Objective: To study the effectiveness and safety of laser nucleotomy of the intervertebral cervical disc. Methods: The experimental study was performed in 10 dogs, and each dog was treated with laser nucleolysis in C3-4 and C4-5. The laser energy was turned on in 1.0-second pulses with 1.0 second (C3-4) and 5.0 second (C4-5) pause interval, and the total energy was up to 1000 joules. The temperatures were measured at the place between the posterior longitudinal ligament and the dura and at the vertebral foramen by using a tip type thermometer. Chronic histologic changes were observed by light microscopy at 2-4 weeks after laser irradiation. Results: The temperatures at the place between the posterior longitudinal ligament and the dura and at the vertebral Forman did not exceed 40 degree C when the pause interval was 5 second. Two dogs were euthanized immediately after treatment, and the oval-shaped cavity was observed on the macroscopic view in the nucleus. The cavity measured between 5 mm and 6 mm in long axis and between 2 mm and 4 mm in short. 4 weeks after the laser irradiation, the nucleus pulposus was replaced by cartilaginous cells and fibrous tissues. Conclusion: The laser nucleotomy of the intervertebral cervical disc is effective and feasible at the suitable condition

    In the cervical disc disease, computed tomography (CT) myelographic and conventional myelographic findings were surgically confirmed. The authors classified the disc protrusion into two types, and demonstrated the characteristic features of these two types in CT myelography and conventional myelography. Moreover, the correlation with the localization of the disc protrusion and the laterality of the myelopathy are discussed. All cases were obtained using a late generation scanner and the patient in the supine position with the neck in the neutral position. Using conventional myelography, all examinations were obtained with the neck in a flexion, neutral and extended positions. Twenty-two patients with cervical disc disease operated on by an anterior approach were studied by CT myelography and conventional myelography. According to the style of the compression on the spinal cord, the cervical disc protrusion was classified into two main groups, the subligamentous type and epiligamentous type. This study included 10 patients of the subligamentous type and 12 patients of the epiligamentous type. The localization of the disc protrusion and the laterality of the myelopathy often corresponded with each other. Not only the localization of the lesion, but also the pincer effect, especially the oblique pincer effect, which is reinforced by dynamic factors, are important in the understanding of the manifestations of myelopathy. In the subligamentous type, the main cause of the myelopathy is considered to be the mechanical pressure by the prolapsed nucleus pulposus. In the epiligamentous type, on the other hand, it is believed to be the pincer effect, reinforced by dynamic factors. (author)

    resultados buenos y excelentes, 10% satisfactorios y el 7% malos. Hubo sólo una complicación (3%, que se revirtió con artrodesis anterior. CONCLUSIONES: La artroplastia discal cervical ha demostrado ser un método seguro y eficaz para el tratamiento de casos seleccionados de hernia de disco cervical asociada a la radiculopatía y/o a compresión de la médula espinal en el corto y mediano plazo.OBJECTIVE: To evaluate results of cervical disc arthroplasty with the Bryan prosthesis for treatment of cervicobrachial pain (radiculopathy and spinal cord compression (myelopathy. METHODS: From 2002 to 2007, the CECOL surgical staff has operated 65 patients. Only 28 patients were found in 2010 to a new data collection. The pre- and post-operative evaluation was conducted using the CSOQ questionnaire (Cervical Spine Outcomes Questionnaire. Odom criteria were used only in the postoperative evaluation. Both were translated and adapted to local culture. RESULTS: There was a significant symptomatic and functional improvement in most patients. The reduction of neck pain (axial and brachial pain (radicular was similar. Odom criteria showed 82.1% good and excellent results, 10% satisfactory and 7% poor. There was only one complication (3% which was reversed with anterior arthrodesis. CONCLUSIONS: The total cervical disc arthroplasty has proved to be a safe and effective method to treat selected cases of cervical disc herniation with radiculopathy and/or myelopathy in the short and medium term.

    This study aimed to investigate the short-term effect of hospital-based intensive nonsurgical treatment in lumbar intervertebral disc herniation (IDH) inpatients admitted to an integrated hospital that offers both complementary and alternative medicine (CAM) and conventional medicine treatment. A prospective observational study. A private Korean medicine hospital inpatient setting in Korea. A total of 524 inpatients diagnosed with lumbar IDH admitted from June 1, 2012, to May 31, 2013. The participants received treatment according to a CAM treatment protocol (herbal medicine, acupuncture, bee venom pharmacopuncture, and Chuna manipulation) and conventional medicine treatment as needed. Numeric rating scale (NRS) of low back pain (LBP) and leg pain, Oswestry Disability Index (ODI), and patient global impression of change. The study also assessed whether improvement was obtained over minimal clinically important difference (MCID) in LBP or leg pain. The average hospital stay was 24.4 ± 13.2 days. The majority of patients received CAM treatment and a few selected conventional medicine, such as pain killers (22.7%; 4.2 ± 3.0 administrations) or nerve blocks (14.1%; 1.4 ± 0.7 sessions). At discharge, the average reduction in NRS was 3.18 ± 2.29 (95% confidence interval [CI], 2.99-3.38) for LBP and 2.61 ± 2.60 (95% CI, 2.38-2.83) for leg pain the average reduction in ODI was 19.45 ± 19.53 (95% CI, 17.77-21.12). Two-hundred and seventy patients (51.5%) showed improvement over MCID in both NRS and ODI, 150 (28.6%) in either NRS or ODI, and 104 (19.8%) in neither. Integrated CAM treatment during hospitalization was effective for patients with lumbar IDH who had severe LBP and disability. However, these results must be investigated further to assess whether the effects surpass those seen with placebo and are cost-effective.

    Spinal sagittal imbalance is a widely acknowledged problem, but there is insufficient knowledge regarding its occurrence. In some patients with lumbar disc herniation (LDH), their symptom is similar to spinal sagittal imbalance. The aim of this study is to illustrate the spinopelvic sagittal characteristics and identity the role of spinal musculature in the mechanism of sagittal imbalance in patients with LDH. Twenty-five adults with spinal sagittal imbalance who initially came to our clinic for treatment of LDH, followed by posterior discectomy were reviewed. The horizontal distance between C7 plumb line-sagittal vertical axis (C7PL-SVA) greater than 5 cm anteriorly with forward bending posture is considered as spinal sagittal imbalance. Radiographic parameters including thoracic kyphotic angle (TK), lumbar lordotic angle (LL), pelvic tilting angle (PT), sacral slope angle (SS) and an electromyography(EMG) index 'the largest recruitment order' were recorded and compared. All patients restored coronal and sagittal balance immediately after lumbar discectomy. The mean C7PL-SVA and trunk shift value decreased from (11.6 ± 6.6 cm, and 2.9 ± 6.1 cm) preoperatively to (-0.5 ± 2.6 cm and 0.2 ± 0.5 cm) postoperatively, while preoperative LL and SS increased from (25.3° ± 14.0° and 25.6° ± 9.5°) to (42.4° ± 10.2° and 30.4° ± 8.7°) after surgery (P imbalance caused by LDH is one type of compensatory sagittal imbalance. Compensatory mechanism of spinal sagittal imbalance mainly includes a loss of lumbar lordosis, an increase of thoracic kyphosis and pelvis tilt. Spinal musculature plays an important role in spinal sagittal imbalance in patients with LDH.

    This study defined the incidence and trends of surgeries performed for patients with cervical disc degeneration with and without tobacco use disorder (TUD). This study utilized the Humana Inc. database between 2007 and 2013 to identify patients with cervical disc degeneration with or without myelopathy. International Classification of Diseases, ninth revision (ICD-9) and Current Procedural Terminology (CPT) codes determined the initial diagnosis of disc degeneration, myelopathy status and TUD, whether patients received surgery, and TUD status at surgery. The prevalence of disc degeneration with myelopathy increased by 32.8% between 2007 and 2013, while disc disease with myelopathy and TUD increased by 91.6%. For patients without myelopathy, the prevalence of disc degeneration alone increased by 65.4%, and disc degeneration with myelopathy increased by 148.7%. Of myelopathy patients, 1717 (6.4%) had TUD and 1024 (59.6%) received surgery, compared to 6508 patients without TUD (26.1%). For patients without myelopathy, 11,337 (3.5%) had TUD and 787 (6.9%) underwent surgery, compared to 9716 patients (3%) without TUD. Of surgical patients, 781 (76.3%) with myelopathy and TUD still had a TUD diagnosis at surgery, and 542 (68.9%) of patients without myelopathy still had a TUD diagnosis at surgery. The prevalence of degenerative disc disease and TUD has increased more than disc disease alone. Patients with TUD were more likely to get surgery, and to have surgeries earlier than patients without TUD. Patients with TUD at the time of the diagnosis of their disc degeneration likely still had a TUD diagnosis at the time of surgery.

    Full Text Available PURPOSE: To carry out a systematic review and meta-analysis of the efficacy of chemonucleolysis in the treatment of lumbar disc herniation. METHODS: Clinical trials were selected from 3 electronic databases (The Cochrane Controlled Trials Register, MEDLINE, and EMBASE. Data were analyzed with the software STATA, using the meta command. RESULTS: Twenty-two clinical trials were eligible. For chemonucleolysis versus placebo, the summary risk ratio estimate for pain relief as outcome was 1.51 (95% CI: 1.27-1.80. The summary estimate was 1.07 (95% CI: 0.95-1.20 for the comparison between chymopapain and collagenase. Regarding chemonucleolysis with chymopapain versus surgery, the fixed-effect summary estimate of effect for pain relief was 0.93 (95% CI: 0.88-0.98 with surgery as the reference group. In this case, heterogeneity was statistically significant. CONCLUSIONS: Chemonucleolysis with chymopapain was superior to placebo and was as effective as collagenase in the treatment of lumbar disc prolapse. Results for studies comparing chemonucleolysis with surgery were heterogeneous, making it difficult to interpret the summary measure of effect.OBJETIVO: Avaliar a eficácia da quimonucleólise no tratamento da hérnia de disco lombar por meio de uma metanálise de ensaios clínicos.

    A prospective study made into cervical disc hernias. To determine the kinesthetic sense and hand functions, which are important for the patients with cervical disc hernia to return to work life and daily activities that need skill. Neurosurgical department. Data Symptoms in cervical disc hernias and hand functions are affected depending on long-term pain. The evaluation of the hand is essential in assessing the patients' overall recovery and ability to return to daily activities and work life. Thirty-four patients with cervical disc hernia, who were operated on, were included in the study. Eight different test positions in the assessment of the hand's kinesthetic sense and hand function sort (HFS) in the evaluation of the hand function were applied. The disability levels of the patients were determined with The Neck Pain and Disability Scale, on the preoperative and postoperative discharge day and in the postoperative second month. Patients were divided into groups according to the side involved. In the evaluation of the kinesthetic test of the hand, only in the postoperative second month was a significant difference observed between the 1, 2, 3, and 4 test positions of the right side of the groups. On the other hand, no significant difference was found between the groups in the assessment of the hand function. In the measurement of hand functions and disability levels, strong and important correlations were determined. An early assessment of the hand's kinesthetic sense and function is instrumental in the patients' evaluation of recovery and resumption of work.

    2007-01-01

    Two aged dogs with chronic obstructive airway disease were evaluated because of intermittent swelling of the ventral cervical region. Radiographs made at expiration and caudal positioning of the forelimbs allowed identification of intermittent cervical lung herniation of the left and right cranial lung lobe in both dogs. Pulmonary hyperinflation, increased expiratory effort, and chronic coughing were considered responsible for the lung herniation. Cervical lung hernia should be included in the differential diagnoses of intermittent cervical swelling in dogs with chronic respiratory disorders associated with increased expiratory effort and chronic coughing.

    To evaluate glycosaminoglycan chemical exchange saturation transfer (gagCEST) imaging at 3T in the assessment of the GAG content of cervical IVDs in healthy volunteers. Forty-two cervical intervertebral discs of seven healthy volunteers (four females, three males; mean age: 21.4 ± 1.4 years; range: 19-24 years) were examined at a 3T MRI scanner in this prospective study. The MRI protocol comprised standard morphological, sagittal T2 weighted (T2w) images to assess the magnetic resonance imaging (MRI) based grading system for cervical intervertebral disc degeneration (IVD) and biochemical imaging with gagCEST to calculate a region-of-interest analysis of nucleus pulposus (NP) and annulus fibrosus (AF). GagCEST of cervical IVDs was technically successful at 3T with significant higher gagCEST values in NP compared to AF (1.17 % ± 1.03 % vs. 0.79 % ± 1.75 %; p = 0.005). We found topological differences of gagCEST values of the cervical spine with significant higher gagCEST effects in lower IVDs (r = 1; p = 0). We could demonstrate a significant, negative correlation between gagCEST values and cervical disc degeneration of NP (r = -0.360; p = 0.019). Non-degenerated IVDs had significantly higher gagCEST effects compared to degenerated IVDs in NP (1.76 % ± 0.92 % vs. 0.52 % ± 1.17 %; p < 0.001). Biochemical imaging of cervical IVDs is feasible at 3T. GagCEST analysis demonstrated a topological GAG distribution of the cervical spine. The depletion of GAG in the NP with increasing level of morphological degeneration can be assessed using gagCEST imaging. (orig.)

    The cervical total disc replacement (cTDR) was developed to treat cervical degenerative disc disease while preserving motion. Cost-effectiveness of this intervention was established by looking at 2-year follow-up, and this update reevaluates our analysis over 5 years. Data were derived from a randomized trial of 330 patients. Data from the 12-Item Short Form Health Survey were transformed into utilities by using the SF-6D algorithm. Costs were calculated by extracting diagnosis-related group codes and then applying 2014 Medicare reimbursement rates. A Markov model evaluated quality-adjusted life years (QALYs) for both treatment groups. Univariate and multivariate sensitivity analyses were conducted to test the stability of the model. The model adopted both societal and health system perspectives and applied a 3% annual discount rate. The cTDR costs $1687 more than anterior cervical discectomy and fusion (ACDF) over 5 years. In contrast, cTDR had $34 377 less productivity loss compared with ACDF. There was a significant difference in the return-to-work rate (81.6% compared with 65.4% for cTDR and ACDF, respectively; P = .029). From a societal perspective, the incremental cost-effective ratio (ICER) for cTDR was -$165 103 per QALY. From a health system perspective, the ICER for cTDR was $8518 per QALY. In the sensitivity analysis, the ICER for cTDR remained below the US willingness-to-pay threshold of $50 000 per QALY in all scenarios (-$225 816 per QALY to $22 071 per QALY). This study is the first to report the comparative cost-effectiveness of cTDR vs ACDF for 2-level degenerative disc disease at 5 years. The authors conclude that, because of the negative ICER, cTDR is the dominant modality.

    Anterior cervical discectomy and fusion (ACDF) and cervical disc replacement (CDR) are both acceptable surgical options for the treatment of cervical myelopathy and radiculopathy. To date, there are limited economic analyses assessing the relative cost-effectiveness of two-level ACDF versus CDR. The purpose of this study was to determine the 5-year cost-effectiveness of two-level ACDF versus CDR. The study design is a secondary analysis of prospectively collected data. Patients in the Prestige cervical disc investigational device exemption (IDE) study who underwent either a two-level CDR or a two-level ACDF were included in the study. The outcome measures were cost and quality-adjusted life years (QALYs). A Markov state-transition model was used to evaluate data from the two-level Prestige cervical disc IDE study. Data from the 36-item Short Form Health Survey were converted into utilities using the short form (SF)-6D algorithm. Costs were calculated from the payer perspective. QALYs were used to represent effectiveness. A probabilistic sensitivity analysis (PSA) was performed using a Monte Carlo simulation. The base-case analysis, assuming a 40-year-old person who failed appropriate conservative care, generated a 5-year cost of $130,417 for CDR and $116,717 for ACDF. Cervical disc replacement and ACDF generated 3.45 and 3.23 QALYs, respectively. The incremental cost-effectiveness ratio (ICER) was calculated to be $62,337/QALY for CDR. The Monte Carlo simulation validated the base-case scenario. Cervical disc replacement had an average cost of $130,445 (confidence interval [CI]: $108,395-$152,761) with an average effectiveness of 3.46 (CI: 3.05-3.83). Anterior cervical discectomy and fusion had an average cost of $116,595 (CI: $95,439-$137,937) and an average effectiveness of 3.23 (CI: 2.84-3.59). The ICER was calculated at $62,133/QALY with respect to CDR. Using a $100,000/QALY willingness to pay (WTP), CDR is the more cost-effective strategy and would be selected

    1988-01-01

    Thirty patients with symptoms of disk herniation and no previous surgery were examined with Gd-DTPA-enhanced MR imaging. Studies obtained before and after administration of Gd-DTPA included the following sequences: sagittal and axial spin echo (SE) 500/17 (repetition time, msec/echo time, msec), sagittal SE 2,000/60, sagittal FLASH 200/13/60. Studies were interpreted separately for presence of extradural disease (EDD) characterized by morphology, mass effect, and enhancement. Post Gd-DTPA diagnoses were: normal, n = 1; herniation, n = 28; neoplasm, n = 1. Tissue diagnosis was obtained in 13. The Gd-DTPA examination correctly changed the diagnosis in one case, provided increased confidence in the diagnosis in four, and was equivalent to the precontrast study in eight. Increased conspicuity of EDD with Gd-DTPA was related to the enhancement of epidural space analogous to IV CT and enhancement of scar surrounding disk herniation. Histologically, this scar was identical to that seen in postoperative spines, Gd-DTPA appears to be a useful adjunct in cervical and thoracic degenerative disk disease

  3. Value of preoperative cervical discography

    2006-01-01

    The aim of this study was to describe the method and the value of cervical discography as correlated with the MR findings. Twenty-one discs in 11 consecutive patients who underwent cervical discography were analyzed. MR and CT discography (CTD) were performed in all patients. Discography was performed after swallowing barium for visualizing the pharynx and the esophagus to prevent penetration. We also analyzed the preceding causes of the subjects' cervical pain. The results of the pain provocation test were classified into concordant pain, discordant pain and a negative test. MRI was analyzed according to the T2-signal intensity (SI) of the disc, disc height, annular bulging and disc herniation. The CTD was analyzed for degeneration or radial tear of the disc, epidural leakage of the contrast agent and pooling of the contrast agent at the periphery of the disc. The pain provocation tests were correlated with the MR and CTD findings. We used the chi-square test to analyze the results. Concordant pain was observed in 14 cases, discordant pain in 3 cases and there were negative tests in 4 cases. There were no complications related to the procedure. Four patients had undergone anterior cervical fusion and four patients that developed after traffic injuries. The decreased T2-SI and annular bulging on MRI, disc degeneration and peripheral pooling of the contrast agent on CT were significantly correlated with pain provocation. When the diagnosis of disc disease is difficult with performing MRI, cervical discography with using swallowed barium solution to reduce the penetration of the esophagus or hypopharynx may play be helpful. The decreased T2-SI and annular bulging on MRI correlated significantly with a positive result on the pain provocation test

    To study the characteristics and changes in the total Oswestry Disability Index (ODI) and in its ten component items in female and male patients pre- and post-surgery for lumbar disc herniation. Ninety-eight patients [mean (SD) age 43 (13), 61% males] undergoing lumbar disc herniation surgery were selected for this clinical 12-month follow-up. Subjective disability and back and leg pain were assessed by ODI version 1.0 and the visual analog scale. Pre-operatively females had a significantly higher mean (SD) total ODI [59(3)] than males [51(2)] (P = 0.030). Females were more disabled in the walking, sex life, social life and travelling items of the ODI compared to males. The total Oswestry decreased by 38 (95% CI − 44 to − 31) in females and by 34 (− 39 to − 30) in males at the 1-year follow-up. Most of the improvement (88% in females and 80% in males) occurred during the first 6 weeks; thereafter the changes were minor. In males the changes were greatest in pain, social life and travelling and in females in walking, social life and travelling. Internal consistency value of ODI was 0.88 (95% CI 0.82–0.91). Item analysis of the ODI showed that all the items except pain had high corrected item correlation. As recovery following lumbar disc surgery occurred to a great extent during the first 6 weeks, the early post-operative outcome appears to be quite a reliable indicator of the overall post-operative outcome over the 1-year follow-up. The ODI proved to capture a wide range of disability in these lumbar disc surgery patients, thereby supporting the future use of the index. The “pain intensity” component, which collects data on the use of painkillers in version 1.0 of the ODI did not support the item structure of the index in this study. The use of ODI version 2.0 might remove this problem. PMID:16912888

    The aim of this study was to document the prevalence of degenerative intervertebral disc changes in the patients who previously reported symptoms of neck pain and to determine the influence of education level on degenerative intervertebral disc changes and subsequent chronic neck pain. One hundred and twelve patients were randomly selected from the University Hospital in Mostar, Bosna and Herzegovina, (aged 48.5±12.7 years) and submitted to magnetic resonance imaging (MRI) of the cervical spine. MRI of 3.0 T (Siemens, Skyrim, Erlangen, Germany) was used to obtain cervical spine images. Patients were separated into two groups based on their education level: low education level (LLE) and high education level (HLE). Pfirrmann classification was used to document intervertebral disc degeneration, while self-reported chronic neck pain was evaluated using the previously validated Oswestry questionnaire. The entire logistic regression model containing all predictors was statistically significant, (χ 2 (3)=12.2, p=0.02), and was able to distinguish between respondents who had chronic neck pain and vice versa. The model explained between 10.0% (Cox-Snell R 2 ) and 13.8% (Nagelkerke R 2 ) of common variance with Pfirrmann classification, and it had the strength to discriminate and correctly classify 69.6% of patients. The probability of a patient being classified in the high or low group of degenerative disc changes according to the Pfirrmann scale was associated with the education level (Wald test: 5.5, p=0.02). Based on the Pfirrmann assessment scale, the HLE group was significantly different from the LLE group in the degree of degenerative changes of the cervical intervertebral discs (U=1,077.5, p=0.001). A moderate level of intervertebral disc degenerative changes (grade II and III) was equally matched among all patients, while the overall results suggest a higher level of education as a risk factor leading to cervical disc degenerative changes, regardless of age

    Systematic review. To assess the efficacy of Chinese herbal medicines in treating chronic neck pain with radicular signs or symptoms. Chronic neck pain with radicular signs or symptoms is a common condition. Many patients use complementary and alternative medicine, including traditional Chinese medicine, to address their symptoms. We electronically searched CENTRAL, MEDLINE, EMBASE, CINAHL, and AMED (up to 2009), the Chinese Biomedical Database and related herbal medicine databases in Japan and South Korea (up to 2007). We also contacted content experts and hand searched a number of journals published in China.We included randomized controlled trials with adults with a clinical diagnosis of cervical degenerative disc disease, cervical radiculopathy, or myelopathy supported by appropriate radiologic findings. The interventions were Chinese herbal medicines. The primary outcome was pain relief, measured with a visual analogue scale, numerical scale, or other validated tool. All 4 included studies were in Chinese; 2 of which were unpublished. Effect sizes were not clinically relevant and there was low quality evidence for all outcomes due to study limitations and sparse data (single studies). Two trials (680 participants) found that Compound Qishe Tablets relieved pain better in the short-term than either placebo or Jingfukang; one trial (60 participants) found than an oral herbal formula of Huangqi relieved pain better than Mobicox or Methycobal, and another trial (360 participants) showed that a topical herbal medicine, Compound Extractum Nucis Vomicae, relieved pain better than Diclofenac Diethylamine Emulgel. There is low quality evidence that an oral herbal medication, Compound Qishe Tablet, reduced pain more than placebo or Jingfukang and a topical herbal medicine, Compound Extractum Nucis Vomicae, reduced pain more than Diclofenac Diethylamine Emulgel. Further research is very likely to change both the effect size and our confidence in the results.

    There is very little literature examining optimal radiographic parameters for placement of cervical disc arthroplasty (CDA), nor is there substantial evidence evaluating the relationship between persistent postoperative neck pain and radiographic outcomes. We set out to perform a single-center evaluation of the radiographic outcomes, including associated complications, of CDA. This is a retrospective review. Two hundred eighty-five consecutive patients undergoing CDA were included in the review. The outcome measures were radiological parameters (preoperative facet arthrosis, disc height, CDA placement in sagittal and coronal planes, heterotopic ossification [HO] formation, etc.) and patient outcomes (persistent pain, recurrent pain, new-onset pain, etc.). We performed a retrospective review of all patients from a single military tertiary medical center from August 2008 to August 2012 undergoing CDA. Preoperative, immediate postoperative, and final follow-up films were evaluated. The clinical outcomes and complications associated with the procedure were also examined. The average radiographic follow-up was 13.5 months and the rate of persistent axial neck pain was 17.2%. For patients with persistent neck pain, the rate of HO formation per level studied was 22.6%, whereas the rate was significantly lower for patients without neck pain (11.7%, p=.03). There was no significant association between the severity of HO and the presence of neck pain. Patients with a preoperative diagnosis of cervicalgia, compared to those without cervicalgia, were significantly more likely to experience continued neck pain postoperatively (28.6% vs. 13.1%, p=.01). There were no differences in preoperative facet arthrosis, pre- or postoperative disc height, segmental range of motion, or placement of the device relative to the posterior edge of the vertebral body.However, patients with implants more centered between the uncovertebral joints were more likely to experience posterior neck pain

  8. Comparison of 2 Zero-Profile Implants in the Treatment of Single-Level Cervical Spondylotic Myelopathy: A Preliminary Clinical Study of Cervical Disc Arthroplasty versus Fusion.

    Sheng Shi

    Full Text Available Cervical disc arthroplasty (CDA with Discover prosthesis or anterior cervical discectomy and fusion (ACDF with Zero-P cage has been widely used in the treatment of cervical spondylotic myelopathy (CSM. However, little is known about the comparison of the 2 zero-profile implants in the treatment of single-level CSM. The aim was to compare the clinical outcomes and radiographic parameters of CDA with Discover prosthesis and ACDF with Zero-P cage for the treatment of single-level CSM.A total of 128 consecutive patients who underwent 1-level CDA with Discover prosthesis or ACDF with Zero-P cage for single-level CSM between September 2009 and December 2012 were included in this study. Clinical outcomes were evaluated using the Japanese Orthopaedic Association (JOA score and Neck Disability Index (NDI. For radiographic assessment, the overall sagittal alignment (OSA, functional spinal unit (FSU angle, and range of motion (ROM at the index and adjacent levels were measured before and after surgery. Additionally, the complications were also recorded.Both treatments significantly improved all clinical parameters (P 0.05. Besides, no significant differences existed in dysphagia, subsidence, or adjacent disc degeneration between the 2 groups (P > 0.05. However, significant differences occurred in prosthesis migration in CDA group.The results of this study showed that clinical outcomes and radiographic parameters were satisfactory and comparable with the 2 techniques. However, more attention to prosthesis migration of artificial cervical disc should be paid in the postoperative early-term follow-up.

    1994-01-01

    The purpose of this study was to compare changes in clinical symptoms and sequential findings of magnetic resonance imaging (MRI) in 66 patients managed with conservative treatment for lumbar disc herniation. In all but 12 patients, there was a good correlation between leg pain and MRI findings, although findings of MRI tended to slightly follow symptom improvement. A notable reduction of herniated mass was seen in a high frequency in sequentrated herniation from an extremely degenerated lumbar disk. The greater the degree of sequentration, the greater the reduction of herniated mass. A shorter duration of leg pain was significantly associated with greater reduction of the herniated mass; leg pain disappeared within 2 months when the herniated mass disappeared on MRI. Because herniated mass disappeared within a short period of time, the involvement of immune reaction was suggested, as well as the possibility of sequentration, degeneration, and phagocytosis.

    Abstract The predictive factors associated with neck pain remain unclear. We conducted a cross-sectional study to assess predictive factors, especially Modic changes (MCs), associated with the intensity and duration of neck pain in patients with cervical disc degenerative disease. We retrospectively reviewed patients in our hospital from January 2013 to December 2016. Severe neck pain (SNP) and persistent neck pain (PNP) were the 2 main outcomes, and were assessed based on the numerical rating scale (NRS). Basic data, and also imaging data, were collected and analyzed as potential predictive factors. Univariate analysis and multiple logistic regression analysis were performed to assess the predictive factors for neck pain. In all, 381 patients (193 males and 188 females) with cervical degenerative disease were included in our study. The number of patients with SNP and PNP were 94 (24.67%) and 109 (28.61%), respectively. The NRS of neck pain in patients with type 1 MCs was significantly higher than type 2 MCs (4.8 ± 0.9 vs 3.9 ± 1.1; P = .004). The multivariate logistic analysis showed that kyphosis curvature (odds ratio [OR] 1.082, 95% confidence interval [CI] 1.044–1.112), spondylolisthesis (OR 1.339, 95% CI 1.226–1.462), and annular tear (OR 1.188, 95% CI 1.021–1.382) were factors associated with SNP, whereas kyphosis curvature (OR 1.568, 95% CI 1.022–2.394), spondylolisthesis (OR 1.486, 95% CI 1.082–2.041), and MCs (OR 1.152, 95% CI 1.074–1.234) were associated with PNP. We concluded that kyphosis curvature, spondylolisthesis, and annular tear are associated with SNP, whereas kyphosis curvature, spondylolisthesis, and MCs are associated with PNP. This study supports the view that MCs can lead to a long duration of neck pain. PMID:29069048

    Many meta-analyses have been performed to study the efficacy of cervical disc arthroplasty (CDA) compared with anterior cervical discectomy and fusion (ACDF); however, there are few data referring to adjacent segment within these meta-analyses, or investigators are unable to arrive at the same conclusion in the few meta-analyses about adjacent segment. With the increased concerns surrounding adjacent segment degeneration (ASDeg) and adjacent segment disease (ASDis) after anterior cervical surgery, it is necessary to perform a comprehensive meta-analysis to analyze adjacent segment parameters. To perform a comprehensive meta-analysis to elaborate adjacent segment motion, degeneration, disease, and reoperation of CDA compared with ACDF. Meta-analysis of randomized controlled trials (RCTs). PubMed, Embase, and Cochrane Library were searched for RCTs comparing CDA and ACDF before May 2016. The analysis parameters included follow-up time, operative segments, adjacent segment motion, ASDeg, ASDis, and adjacent segment reoperation. The risk of bias scale was used to assess the papers. Subgroup analysis and sensitivity analysis were used to analyze the reason for high heterogeneity. Twenty-nine RCTs fulfilled the inclusion criteria. Compared with ACDF, the rate of adjacent segment reoperation in the CDA group was significantly lower (panalysis. There was no statistically significant difference in ASDeg between CDA and ACDF within the 24-month follow-up period; however, the rate of ASDeg in CDA was significantly lower than that of ACDF with the increase in follow-up time (p.05). Cervical disc arthroplasty provided a lower adjacent segment range of motion (ROM) than did ACDF, but the difference was not statistically significant. Compared with ACDF, the advantages of CDA were lower ASDeg and adjacent segment reoperation. However, there was no statistically significant difference in ASDis and adjacent segment ROM.

    The typically accepted surgical procedure for cervical disc pathology has been the anterior cervical discectomy and fusion (ACDF), although recent trials have demonstrated equivalent or improved outcomes with cervical disc arthroplasty (CDA). Trends for these two procedures regarding utilization, revision procedures, and other demographic information have not been sufficiently explored. The present study aims to provide data regarding ACDF and CDA from 2006 to 2013 in the United States. The present study is a retrospective national database analysis. The present study included 20% sample of discharges from US hospitals, which is weighted to provide national estimates. Functional measures such as national incidence, hospital costs, length of stay (LOS), routine discharge, revision burden, and patient characteristics were used in the present study. Patients from the National Inpatient Sample (NIS) database who underwent primary ACDF, revision ACDF, primary CDA, and revision CDA from 2006 to 2013 were included. Demographic and economic data for the procedures' respective International Classification of Diseases, Ninth Revision, Clinical Modification codes were collected. A total of 1,059,403 ACDF and 13,099 CDA surgeries were performed in the United States from 2006 to 2013. The annual number of ACDF increased by 5.7% nonlinearly from 120,617 in 2006 to 127,500 in 2013 (mean per year 132,425; range 120,617-147,966); CDA increased by 190% nonlinearly from 540 in 2006 to 1,565 in 2013 (mean per year 1,637; range 540-2,381). Cervical disc arthroplasty patients were younger and had more private or "other" insurance, including worker's compensation (p<.0001). Mean LOS was longer for ACDF (ACDF 2.3 days vs. CDA 1.5; p<.0001). Routine discharge was higher in the CDA group (CDA 96% vs. ACDF 89%; p-value<.0001). The mean hospital-related cost was more expensive for ACDF (ACDF $16,178 vs. CDA $13,197; p-value=.0007). Cervical disc arthroplasty mean revision burden, defined as

    OBJECTIVE Seven cervical total disc replacement (TDR) devices have received FDA approval since 2006. These devices represent a heterogeneous assortment of implants made from various biomaterials with different biomechanical properties. The majority of these devices are composed of metallic endplates with a polymer core. In this prospective, randomized multicenter study, the authors evaluate the safety and efficacy of a metal-on-metal (MoM) TDR (Kineflex|C) versus anterior cervical discectomy and fusion (ACDF) in the treatment of single-level spondylosis with radiculopathy through a long-term (5-year) follow-up. METHODS An FDA-regulated investigational device exemption (IDE) pivotal trial was conducted at 21 centers across the United States. Standard validated outcome measures including the Neck Disability Index (NDI) and visual analog scale (VAS) for assessing pain were used. Patients were randomized to undergo TDR using the Kineflex|C cervical artificial disc or anterior cervical fusion using structural allograft and an anterior plate. Patients were evaluated preoperatively and at 6 weeks and 3, 6, 12, 24, 36, 48, and 60 months after surgery. Serum ion analysis was performed on a subset of patients randomized to receive the MoM TDR. RESULTS A total of 269 patients were enrolled and randomly assigned to undergo either TDR (136 patients) or ACDF (133 patients). There were no significant differences between the TDR and ACDF groups in terms of operative time, blood loss, or length of hospital stay. In both groups, the mean NDI scores improved significantly by 6 weeks after surgery and remained significantly improved throughout the 60-month follow-up (both p < 0.01). Similarly, VAS pain scores improved significantly by 6 weeks and remained significantly improved through the 60-month follow-up (both p < 0.01). There were no significant changes in outcomes between the 24- and 60-month follow-ups in either group. Range of motion in the TDR group decreased at 3 months but

    We wished to evaluate the incidence of non-contiguous spinal injury in the cervicothoracic junction (CTJ) or the upper thoracic spines on cervical spinal MR images in the patients with cervical spinal injuries. Seventy-five cervical spine MR imagings for acute cervical spinal injury were retrospectively reviewed (58 men and 17 women, mean age: 35.3, range: 18-81 years). They were divided into three groups based on the mechanism of injury; axial compression, hyperflexion or hyperextension injury, according to the findings on the MR and CT images. On cervical spine MR images, we evaluated the presence of non-contiguous spinal injury in the CTJ or upper thoracic spine with regard to the presence of marrow contusion or fracture, ligament injury, traumatic disc herniation and spinal cord injury. Twenty-one cases (28%) showed CTJ or upper thoracic spinal injuries (C7-T5) on cervical spinal MR images that were separated from the cervical spinal injuries. Seven of 21 cases revealed overt fractures in the CTJs or upper thoracic spines. Ligament injury in these regions was found in three cases. Traumatic disc herniation and spinal cord injury in these regions were shown in one and two cases, respectively. The incidence of the non-contiguous spinal injuries in CTJ or upper thoracic spines was higher in the axial compression injury group (35.5%) than in the hyperflexion injury group (26.9%) or the hyperextension (25%) injury group. However, there was no statistical significance (ρ > 0.05). Cervical spinal MR revealed non-contiguous CTJ or upper thoracic spinal injuries in 28% of the patients with cervical spinal injury. The mechanism of cervical spinal injury did not significantly affect the incidence of the non-contiguous CTJ or upper thoracic spinal injury

  19. Regenerative and immunogenic characteristics of cultured nucleus pulposus cells from human cervical intervertebral discs.

    Stefan Stich

    Full Text Available Cell-based regenerative approaches have been suggested as primary or adjuvant procedures for the treatment of degenerated intervertebral disc (IVD diseases. Our aim was to evaluate the regenerative and immunogenic properties of mildly and severely degenerated cervical nucleus pulposus (NP cells with regard to cell isolation, proliferation and differentiation, as well as to cell surface markers and co-cultures with autologous or allogeneic peripheral blood mononuclear cells (PBMC including changes in their immunogenic properties after 3-dimensional (3D-culture. Tissue from the NP compartment of 10 patients with mild or severe grades of IVD degeneration was collected. Cells were isolated, expanded with and without basic fibroblast growth factor and cultured in 3D fibrin/poly (lactic-co-glycolic acid transplants for 21 days. Real-time reverse-transcription polymerase chain reaction (RT-PCR showed the expression of characteristic NP markers ACAN, COL1A1 and COL2A1 in 2D- and 3D-culture with degeneration- and culture-dependent differences. In a 5,6-carboxyfluorescein diacetate N-succinimidyl ester-based proliferation assay, NP cells in monolayer, regardless of their grade of degeneration, did not provoke a significant proliferation response in T cells, natural killer (NK cells or B cells, not only with donor PBMC, but also with allogeneic PBMC. In conjunction with low inflammatory cytokine expression, analyzed by Cytometric Bead Array and fluorescence-activated cell sorting (FACS, a low immunogenicity can be assumed, facilitating possible therapeutic approaches. In 3D-culture, however, we found elevated immune cell proliferation levels, and there was a general trend to higher responses for NP cells from severely degenerated IVD tissue. This emphasizes the importance of considering the specific immunological alterations when including biomaterials in a therapeutic concept. The overall expression of Fas receptor, found on cultured NP cells, could have

    The high prevalence of chronic persistent neck pain not only leads to disability but also has a significant economic, societal, and health impact. Among multiple modalities of treatments prescribed in the management of neck and upper extremity pain, surgical, interventional and conservative modalities have been described. Cervical epidural injections are also common modalities of treatments provided in managing neck and upper extremity pain. They are administered by either an interlaminar approach or transforaminal approach. To determine the long-term efficacy of cervical interlaminar and transforaminal epidural injections in the treatment of cervical disc herniation, spinal stenosis, discogenic pain without facet joint pain, and post surgery syndrome. The literature search was performed from 1966 to October 2014 utilizing data from PubMed, Cochrane Library, US National Guideline Clearinghouse, previous systematic reviews, and cross-references. The evidence was assessed based on best evidence synthesis with Level I to Level V. There were 7 manuscripts meeting inclusion criteria. Of these, 4 assessed the role of interlaminar epidural injections for managing disc herniation or radiculitis, and 3 assessed these injections for managing central spinal stenosis, discogenic pain without facet joint pain, and post surgery syndrome. There were 4 high quality manuscripts. A qualitative synthesis of evidence showed there is Level II evidence for each etiology category. The evidence is based on one relevant, high quality trial supporting the efficacy of cervical interlaminar epidural injections for each particular etiology. There were no randomized trials available assessing the efficacy of cervical transforaminal epidural injections. Paucity of available literature, specifically conditions other than disc herniation. This systematic review with qualitative best evidence synthesis shows Level II evidence for the efficacy of cervical interlaminar epidural injections with local

    cem pacientes com diagnóstico de hérnia de disco lombar, comprovada com ressonância magnética e discografia evocativa positiva. Todos os pacientes nunca tinham passado por um tratamento cirúrgico e foi feito um seguimento por dois anos. RESULTADOS: os resultados foram classificados em bons, regulares e ruins. Foram encontrados bons resultados em 82 pacientes, regulares em 10 e ruins em 8. CONCLUSÕES: os resultados do tratamento da hérnia de disco lombar, com a endoscopia lateral e com o sistema YESS são, até o momento, similares àqueles com abordagem posterior aberta, mesmo que o tempo de recuperação e a capacidade sejam menores, assim como também o custo, pois é um procedimento ambulatório.INTRODUCTION: in the patients with lumbar disc herniation, who are candidates to surgical procedures, the open diskectomy has been the gold standard for many years. Nevertheless, the complications of this procedure, in which the medullar canal is invaded, have caused other means to be developed. One of them is the YESS system (Young Endoscopic Spine System. OBJECTIVE: to examine the results of one hundred patients with lumbar disc herniation, treated with the YESS system. METHODS: it was studied one hundred patients with lumbar disc herniation, which was proved with magnetic resonance imaging and discography, and their results were positive. None of the patients had ever undergone a surgical procedure; therefore, they were tracked for two years. RESULTS: results were classified into good, regular, and bad. In 82 patients good results were found, 10 were regular, and 8 were bad. CONCLUSIONS: the results of the treatment for a lumbar disc herniation with the YESS system are so far similar to open back surgery, even though the time of recovery, disability, and costs are lower because it is an ambulatory procedure.

    2008, buscando identificar os fatores que têm relação com a doença; também se analisaram os casos de pacientes submetidos à cirurgia primária de hérnia de disco lombar. RESULTADOS: Foram analisados os casos de 20 pacientes com hérnia de disco lombar recidivante e 27 casos de cirurgia primária de hérnia de disco lombar. Para os pacientes com recorrência, constatou-se que 95% tinham algum grau de obesidade, determinada pela fórmula de Quetelet, baseada no Índice de Massa Corporal; e também foi observado que 75% dos casos eram protrusão do disco com excelentes resultados em 35% e bons em 55%; 10% tiveram problemas residual grave. Foram estudados 27 casos de pacientes com hérnia primária, nos quais se verificou que 92% foram operados antes dos 6 meses do início do quadro, 38% tiveram resultados excelentes, 40%, bom e 19%, resultado ruim. Ao considerar as variáveis com a relação de Pearson encontrou-se relação da recorrência com tabagismo, trabalho, diabetes, hipertensão e escolaridade, mas não com a obesidade. CONCLUSÃO: É importante ressaltar que dois dos fatores estão sujeitos a alteração antes da cirurgia ou depois dela, o que pode beneficiar o resultado do mesmo.OBJECTIVE: Recurrent lumbar disc herniation is a condition that involves some difficulties in relation to diagnosis and treatment. It is important to identify factors that may influence recurrence. METHODS: We reviewed cases of patients operated for recurrent lumbar disc herniation between 2006 and 2008, seeking to identify the factors that have relation with this disease, and also reviewed the cases of patients that underwent primary surgery for herniated lumbar disc. RESULTS: We analyzed the cases of 20 patients with recurrent lumbar disc herniation and 27. For patients with recurrence, it was found that 95% had some degree of obesity determined by the Quetelet Index, based on Body Mass Index; it was also observed that 75% of cases were protruding with excellent results in 35

    We report a case of awake intubation utilizing Pentax-AWS Airwayscope in semi-sitting position. A 74-year-old man with myasthenia gravis and cervical disc hernia was scheduled for distal gastrectomy under general anesthesia. He could not move his head due to severe cervical disc hernia and also could not sufficiently breathe due to the fatigue of respiratory muscles by myasthenia gravis in supine position. With fentanyl bolus administration and lidocaine spray for laryngotracheal anesthesia, we performed awake intubation in semi-sitting position with AWS from cranial side. The patient did not buck during intubation and no hemodynamic change was observed.

    Decisions about the treatment of neck pain are largely made on the basis of information gained from plain X-rays and magnetic resonance imaging (MRI), which are used routinely as part of preliminary investigation. We performed a descriptive cadaveric study to compare histology with radiography and MRI. We correlated plain radiography, disc height [Farfan index (FI)] and MRI findings with histology to assess the ability of radiology to detect significant pathologic lesions. The study included 52 motion segments from nine subjects over the age of 50, who underwent routine hospital autopsy. Disc degeneration was assessed by histology, radiography, disc height (FI: anterior disc height plus posterior disc height divided by anterioposterior diameter) and MRI using established grading systems. Most of the discs were classified radiologically as grade 1 (19/52), grade 2 (13/52), grade 3 (9/52) or grade 4 (3/52). Eight of the discs were graded as normal. The distribution of MRI grades was grade 0 (9/36), grade 1 (9/36), grade 2 (7/36), grade 3 (8/36) and grade 4 (3/36). Half of the discs (26/52) showed advanced (grade 4) degeneration histologically. FI correlated with histological grade (P=0.013), MRI grade (P=0.02) and radiological grade (P<0.001) of degeneration. Radiological and histological grade of degeneration showed a weak correlation (r=0.3, P=0.033). MRI correlated with overall histological grade (r=0.41, P=0.015, n=34). Histological features (e.g., tears, rim lesions, prolapse of nucleus material) were poorly recognised by MRI, which had a sensitivity for disc material prolapse and annulus tears of less than 40%. Our study showed that discs from patients over 50 years are histologically severely degenerated; however, these changes may not be detected by conventional radiography and MRI. (orig.)

    Nowadays, anterior cervical artificial disc replacement (ACDR) has achieved favorable outcomes in treatment for patients with single-level cervical spondylosis. However, It is still controversial that whether or not it will become a potent therapeutic alternation in treating 2 contiguous levels cervical spondylosis compared with anterior cervical decompression and fusion (ACDF). Therefore, we conducted a systematic review and meta-analysis to compare the efficacy and safety of ACDR and ACDF in patients with 2 contiguous levels cervical spondylosis. According to the computer-based online search, PubMed, Embase, Web of Science, and Cochrane Library for articles published before July 1, 2017 were searched. The following outcome measures were extracted: neck disability index (NDI), visual analog scale (VAS) neck, VAS arm, Short Form (SF)-12 mental component summary (MCS), SF-12 physical component summary (PCS), overall clinical success (OCS), patient satisfaction (PS), device-related adverse event (DRAE), subsequent surgical intervention (SSI), neurological deterioration (ND), and adjacent segment degeneration (ASD). Methodological quality was evaluated independently by 2 reviewers using the Furlan for randomized controlled trial (RCT) and MINORS scale for clinical controlled trials (CCT). The chi-squared test and Higgin I test were used to evaluate the heterogeneity. A P bi-level cervical spondylosis, ACDR appears to provide superior clinical effectiveness and safety effects than ACDF. In the future, more high-quality RCTs are warranted to enhance this conclusion.

    The aim of this case report was to highlight the application of magnetic resonance imaging (MRI) in elucidating serious and occult injuries in a single case of hyperflextion injury of a patient cervical spine (C-Spine). A chart and radiology review was performed to establish the sequence of care and how the results of imaging studies influenced the clinical management in this trauma case. Plain radiographs and computed tomography (CT) imaging modalities of the C-Spine revealed bilateral C4/C5 facetal subluxation with no obvious fractures; however, the MR imaging of the C-Spine revealed a non-contiguous and occult injury to C6/C7 disc with a posterior annular tear and associated disc extrusion. This altered the operative intervention that was initially planned. MR imaging proved an invaluable diagnostic addition in this particular case of cervical trauma in a rugby player following a hyperflextion injury, by revealing a serious non-contiguous and occult injury of the C-Spine.

    Full Text Available Anterior cervical discectomy and fusion is effective surgical modality in the treatment of cervical prolapsed intervertebral disc, radiculopathy and myelopathy. Aims of our study is to evaluate fusion of cervical spine  by ICG with plating and PEEK cage with bone graft, also assess the donor site morbidity. Thirty patients (male 16; female 14 with mean age 46 ± 9.2 years and were distributed  into two treatment groups (PEEK cage group and ICG group. We assess the patients clinically for myelopathy and functional outcome by Nurick scale and Odom's criteria respectively and  neck and arm pain by Visual Analogue Scale (VAS. Eighteen patients were operated for single level discectomy and fusion by either ICG or PEEK cages and twelve patients for two levels. After surgery follow up was 2 years and better  postoperative score which was assessed by Nurick scale, Odoms criteria and VAS score. Total patients 14(93%were graded excellent in the PEEK cage group compared to 13 patients (86% in the ICG group.  Statistically it was not significant between two groups and p value was <0.35. Difference was significant in VAS score  after 24 months with more reduction of pain in PEEK cage group. Fusion occurred in 13 patients (86% of the PEEK cage group and 14 patient (93% of the ICG group. Result showed more fusion rate in ICG group and less donor site morbidity in PEEK group.

    2007-01-01

    To compare the MR findings of a sequestered disc with an extruded disc. MR images of 28 patients with a sequestered disc and 18 patients with an extruded disc were retrospectively reviewed. Patients with sequestered discs were divided into two groups whether definite separation from the parent disc was or was not seen. In the latter group (definite separation not seen) and the extruded disc group of patients, the signal intensities of the herniated discs were compared with the signal intensities of the parent discs and were evaluated on T1-and T2-weighted images. We also assessed the presence of a notch within the herniated disc. In the sequestered disc group of patients (28 discs), only 5 discs (18%) showed obvious separation from the parent disc. Among the remaining 23 discs with indefinite separation, the notch was visible in 14 discs (61%) and 9 discs (39%) had no notch. In the extruded disc group (18 discs), the notch was visible in 2 (11%) discs and the difference between the two groups was statistically significant (ρ 0.0002). The signal intensities of the herniated discs on T1-weighted images were isointense in both the sequestered and extruded discs. The difference of incidence of high signal intensities on T2-weighted images was not statistically significant (ρ = 0.125). It is necessary to consider the possibility of the presence of a sequestered disc when a herniated disc material shows a notch

    Background Past in vitro experiments studying artificial discs have focused on range of motion. It is also important to understand how artificial discs affect other biomechanical parameters, especially alterations to kinematics. The purpose of this in vitro investigation was to quantify how disc replacement with a ball-and-socket disc arthroplasty device (ProDisc-C; Synthes, West Chester, Pennsylvania) alters biomechanics of the spine relative to the normal condition (positive control) and simulated fusion (negative control). Methods Specimens were tested in multiple planes by use of pure moments under load control and again in displacement control during flexion-extension with a constant 70-N compressive follower load. Optical markers measured 3-dimensional vertebral motion, and a strain gauge array measured C4-5 facet loads. Results Range of motion and lax zone after disc replacement were not significantly different from normal values except during lateral bending, whereas plating significantly reduced motion in all loading modes (P biomechanics were less substantial after artificial disc placement than after anterior plating.

    Cervical spondylosis and intervertebral disc (IVD) degeneration are the most common cause for compression of the spinal cord and/or its roots. Total IVD arthroplasty, as a modern alternative to surgical treatment of IVD degeneration, is gaining popularity in many neurosurgical clinics around the world. Aim - the study aim was to conduct a multicenter analysis of cervical spine arthroplasty with an IVD prosthesis M6-C ('Spinal Kinetics', USA). The study included 112 patients (77 males and 35 females). All patients underwent single-level discectomy with implantation of the artificial IVD prosthesis M6-C. The follow-up period was up to 36 months. Dynamic assessment of the prosthesis was based on clinical parameters (pain intensity in the cervical spine and upper extremities (visual analog scale - VAS); quality of life (Neck Disability Index - NDI)); and subjective satisfaction with the results of surgical treatment (Macnab scale) and instrumental data (range of motion in the operated spinal motion segment, degree of heterotopic ossification (McAfee-Suchomel classification), and time course of degenerative changes in the adjacent segments).

    Purpose: To illustrate quantitative discomanometry's (QD) diagnostic efficacy and predictive value in discogenic-pain evaluation in a prospective study correlating intradiscal pressure values with pain reduction after percutaneous image-guided technique (i.e., percutaneous decompression, PD). Materials and Methods: During the last 3 years, 36 patients [21 male and 15 female (mean age 36 {+-} 5.8 years)] with intervertebral disc hernia underwent QD before PD. Under absolute sterilization and fluoroscopy, a mixture of contrast medium and normal saline (3:1 ratio) was injected. A discmonitor performed a constant rate injection and recorded pressure and volume values, thus producing the relative pressure-volume curve. PD was then performed. Pain reduction and improved mobility were recorded at 3, 12, and 24 months after PD using clinical evaluation and a numeric visual scale (NVS; 0 to 10 units). Results: Mean pain values of 7.5 {+-} 1.9 (range 4 to 8) NVS units were recorded before PD; these decreased to 2.9 {+-} 2.44 at 3 months, 1.0 {+-} 1.9 at 12 months, and 1.0 {+-} 1.9 NVS units at 24 months after PD. Recorded correlations (pressure, volume, significant pain-reduction values) with bilateral statistical significance included a maximum injected volume of 2.4 ml (p = 0.045), P{sub o} < 14 psi [initial pressure required to inject 0.1 ml of the mixture inside the disc (p = 0.05)], P{sub max} {<=} 65 psi [greatest pressure value on the curve (p = 0.018)], and P{sub max} - P{sub o} {<=} 47 psi (p = 0.038). Patients meeting these pressure or volume cut-off points, either independently or as a total, had significant pain reduction (>4 NVS units) after PD. No complications were noted. Conclusions: QD is an efficient technique that may have predictive value for discogenic pain evaluation. It might serve as a useful tool for patient selection for intervertebral disc therapies.

  15. Quality of systematic reviews: an example of studies comparing artificial disc replacement with fusion in the cervical spine.

    Tashani, Osama A; El-Tumi, Hanan; Aneiba, Khaled

    2015-01-01

    Cervical artificial disc replacement (C-ADR) is now an alternative to anterior cervical discectomy and fusion (ACDF). Many studies have evaluated the efficacy of C-ADR compared with ACDF. This led to a series of systematic reviews and meta-analyses to evaluate the evidence of the superiority of one intervention against the other. The aim of the study presented here was to evaluate the quality of these reviews and meta-analyses. Medline via Ovid, Embase, and Cochrane Library were searched using the keywords: (total disk replacement, prosthesis, implantation, discectomy, and arthroplasty) AND (cervical vertebrae, cervical spine, and spine) AND (systematic reviews, reviews, and meta-analysis). Screening and data extraction were conducted by two reviewers independently. Two reviewers then assessed the quality of the selected reviews and meta-analysis using 11-item AMSTAR score which is a validated measurement tool to assess the methodological quality of systematic reviews. Screening of full reports of 46 relevant abstracts resulted in the selection of 15 systematic reviews and/or meta-analyses as eligible for this study. The two reviewers' inter-rater agreement level was high as indicated by kappa of >0.72. The AMSTAR score of the reviews ranged from 3 to 11. Only one study (a Cochrane review) scored 100% (AMSTAR 11). Five studies scored below (AMSTAR 5) indicating low-quality reviews. The most significant drawbacks of reviews of a score below 5 were not using an extensive search strategy, failure to use the scientific quality of the included studies appropriately in formulating a conclusion, not assessing publication bias, and not reporting the excluded studies. With a significant exception of a Cochrane review, the methodological quality of systematic reviews evaluating the evidence of C-ADR versus ACDF has to be improved.

    Purpose: To study the influence of (Modic) signal alterations (SA) of the cartilage endplate (CEP) of vertebrae L3-S1 on the outcome of an in-patient minimally invasive treatment (MIT), using epidural injections on patients with lumbar disc herniation (LDH). Materials and Methods: The MR images of 59 consecutive patients with LDH within segments L3/L4-L5/S1 undergoing in-patient minimally invasive treatment with epidural injections were evaluated in a clinical study. The (Modic) signal alterations of the CEP were recorded using T1- and T2-weighted sagittal images. On the basis of the T2-weighted sagittal images, the extension and distribution of the SA were measured by dividing each CEP into 9 areas. The outcome of the MIT was recorded using the Oswestry Disability Index (ODI) before and after therapy and in a 3-month follow-up. Within a subgroup of patients (n=35), the distribution and extension of the signal alterations were correlated with the development of the ODI. Results: Segments with LDH showed significantly more (p<0.001) SA of the CEP than segments without LDH. Although the extension of the SA was not dependent on sex, it did increase significantly with age (p=0.017). The outcome after MIT did not depend on the sex and age of the patients or on the type od LDH. The SA extension tended to have a negative correlation with the outcome after MIT after 3 months (p=0.071). A significant negative correlation could be established between the SA extension in the central section of the upper endplate and the outcome after 3 months (p=0.019). (orig.)

  17. Comparison of lumbar discectomy alone and lumbar discectomy with direct repair of pars defect for patients with disc herniation and spondylolysis at the nearby lumbar segment.

    It is unknown whether direct repair (DR) of pars defect after lumbar discectomy (LD) for patients with lumbar disc herniation (LDH) and spondylolysis leads to better outcomes than LD alone. The aim was to compare two surgical methods, LD alone and LD with DR, for LDH patients with spondylolysis at a nearby lumbar segment. This was a retrospective comparative study. This study enrolled 89 patients who were diagnosed with LDH and spondylolysis at the same or adjacent lumbar segment and were followed up for at least 1 year. The primary outcome was pain intensity of the lower back and lower extremities as measured with visual analog scale. Secondary outcomes included clinical outcomes as assessed with the Oswestry Disability Index and the 12-item short form health survey, radiologic outcomes as assessed with the gap distance and the union rate at the pars defect, surgical outcomes, and complications. Enrolled patients were classified into two groups: LD alone (Group A, 48 patients) and LD with DR (Group B, 41 patients). Pain intensity of the lower back and lower extremities and clinical outcomes were significantly improved 1 year after surgery compared with preoperative scores. However, the scores in the group receiving LD alone steadily worsened during follow-up, whereas the scores in the group receiving LD with DR did not deteriorate over time. The difference in the gap distance of the pars defect between baseline and 1 year after surgery was significantly different between the groups. The fusion rate of the pars defect was 59% (24/41). With the exception of surgical time, which was longer in Group B, surgical outcomes and complications did not differ significantly between the groups. At the 1-year follow-up, DR after LD was associated with better outcomes for LDH with spondylolysis than LD alone. Copyright © 2015 Elsevier Inc. All rights reserved.

    To verify the usefulness of a fluoroscopy guided cervical interlaminar epidural steroid injection (CIESI) in patients with neck pain and cervical radiculopathy and to evaluate outcome predictors. We retrospectively analyzed 91 patients from July 2004 to June 2005 in whom CIESI was initially performed for neck pain and cervical radiculopathy. Therapeutic effects were evaluated 2 weeks after the administration of CIESI, and CIESI effectiveness was graded using a five-point scale, namely, whether the pain had disappeared, was much improved, slightly improved, the same, or aggravated. We also used a visual analog scale (VAS) for the clinical evaluation. According to documentation and follow-up charts, we categorized treatments as effective or ineffective. Possible outcome predictors, namely, diagnosis (spinal stenosis vs herniated disc), primary symptoms (neck pain vs radiculopathy vs both), age, gender, and duration of pain (more or less than 6 months) were also analyzed. Fisher's exact test, the chi-square test, and multiple logistic regression analysis were used for the statistical analysis. After their medical records had been reviewed, 76 patients were included in this study. Inclusion criteria were: the availability of a cross-sectional image, such as a CT scan or an MR image, and a follow-up record after injection. The medical records of 76 patients (male:female = 41: 35) of mean age 53.1 years (range 32 years to 82 years) were reviewed. Two weeks after injection, 55 patients (72.4%) had experienced effective pain relief. Patients with herniated discs had significantly better results than patients with spinal stenosis (86.1% vs 60.0%) (P < 0.05). Other non-significant predictors of an improved outcome included: a symptom duration of <6 months, a young age, and the presence of cervical radiculopathy. Multiple regression analysis showed that the only factor that was significantly associated with outcome was the cause of the pain, i.e., herniated disc or

  20. Compressive cervical pannus formation in a patient after 2-level disc arthroplasty: a rare complication treated with posterior instrumented fusion.

    Brophy, Carl M; Hoh, Daniel J

    2018-06-01

    Cervical disc arthroplasty (CDA) has received widespread attention as an alternative to anterior fusion due to its similar neurological and functional improvement, with the advantage of preservation of segmental motion. As CDA becomes more widely implemented, the potential for unexpected device-related adverse events may be identified. The authors report on a 48-year-old man who presented with progressive neurological deficits 3 years after 2-level CDA was performed. Imaging demonstrated periprosthetic osteolysis of the vertebral endplates at the CDA levels, with a heterogeneously enhancing ventral epidural mass compressing the spinal cord. Diagnostic workup for infectious and neoplastic processes was negative. The presumptive diagnosis was an inflammatory pannus formation secondary to abnormal motion at the CDA levels. Posterior cervical decompression and instrumented fusion was performed without removal of the arthroplasty devices or the ventral epidural mass. Postoperative imaging at 2 months demonstrated complete resolution of the compressive pannus, with associated improvement in clinical symptoms. Follow-up MRI at > 6 months showed no recurrence of the pannus. At 1 year postoperatively, CT scanning revealed improvement in periprosthetic osteolysis. Inflammatory pannus formation may be an unexpected complication of abnormal segmental motion after CDA. This rare etiology of an epidural mass associated with an arthroplasty device should be considered, in addition to workup for other potential infectious or neoplastic mass lesions. In symptomatic individuals, compressive pannus lesions can be effectively treated with fusion across the involved segment without removal of the device.

    Clinically, magnetic resonance (MR) imaging is the most effective non-invasive tool for assessing IVD degeneration. Histological examination of the IVD provides a more detailed assessment of the pathological changes at a tissue level. However, very few reports have studied the relationship between these techniques. Identifying a relationship may allow more detailed staging of IVD degeneration, of importance in targeting future regenerative therapies. To investigate the relationship between MR and histological grading of IVD degeneration in the cervical and lumbar spine in patients undergoing discectomy. Lumbar (N = 99) and cervical (N = 106) IVD samples were obtained from adult patients undergoing discectomy surgery for symptomatic IVD herniation and graded to ascertain a histological grade of degeneration. The pre-operative MR images from these patients were graded for the degree of IVD (MR grade) and vertebral end-plate degeneration (Modic Changes, MC). The relationship between histological and MR grades of degeneration were studied. In lumbar and cervical IVD the majority of samples (93%) exhibited moderate levels of degeneration (ie MR grades 3-4) on pre-operative MR scans. Histologically, most specimens displayed moderate to severe grades of degeneration in lumbar (99%) and cervical spine (93%). MR grade was weakly correlated with patient age in lumbar and cervical study groups. MR and histological grades of IVD degeneration did not correlate in lumbar or cervical study groups. MC were more common in the lumbar than cervical spine (e.g. 39 versus 20% grade 2 changes; p < 0.05), but failed to correlate with MR or histological grades for degeneration. In this surgical series, the resected IVD tissue displayed moderate to severe degeneration, but there is no correlation between MR and histological grades using a qualitative classification system. There remains a need for a quantitative, non-invasive, pre-clinical measure of IVD degeneration that

(4 For treating a patient with cervical pain, the type of pharmacopuncture to be used should be selected based on the cause of the disease and the patient’s condition.

  4. Comparative Study Between M6-C and Mobi-C Cervical Artificial Disc Replacement: Biomechanical Outcomes and Comparison with Normative Data.

    Pham, My; Phan, Kevin; Teng, Ian; Mobbs, Ralph J

    2018-05-01

    Cervical spondylosis affects a huge proportion of the middle-aged population. Degenerative changes can occur in multiple regions of the cervical spine typically affecting the joints, intervertebral discs and endplates. These changes lead to compression of adjacent nervous structures, which results in radiculopathic and myelopathic pain. Various treatment modalities are currently available with non-surgical approaches the initial go to if there is no symptomatic cord compression. Anterior cervical discectomy and fusion, or arthroplasty are the two common surgical approaches if non-surgical treatments fail to relieve symptoms of the patients or there are signs of central cord compression. However, studies have shown that there is an increased risk of adjacent segment disease related to fusion. Cervical disc arthroplasty aims to restore normal range of motion (ROM) in patients with pain and disability due to degenerative disc disease resistant to conservative care. Two common disc prostheses used include M6-C and Mobi-C. Both prostheses comprise a mobile polymer segment sandwiched between two metal endplates with mechanisms resembling an actual intervertebral disc. This study aims to compare the kinematics associated with these prostheses, against the normal range of motion in the non-degenerative population. Patients who underwent M6-C or Mobi-C disc replacements by the senior author from 2012 to 2015 were identified at a single tertiary institution. Routine 3-month postoperative lateral radiographs were analyzed for flexion and extension ROM angles at the involved vertebral level by two independent authors. Data was compared to previous published studies investigating cervical spine ROM of asymptomatic patients. There was no statistical significance in the difference of overall flexion range between M6-C and Mobi-C prostheses. However, overall range of extension of Mobi-C was greater compared to M6-C (P = 0.028). At C 5-6 , the range of flexion for both implants

    2017-09-01

    Full Text Available Stroke is generally considered to be the first preliminary diagnosis in patients presenting with acute hemiparesia in the emergency department. But rarely in unexpected spontaneous neurological pathologies that may lead to hemiparesis. The data from 8 non-traumatic patients who underwent surgical treatment for brown-sequard syndrome (BSS were reviewed retrospectively. All patients were initially misdiagnosed with strokes. Two of the patients had spinal canal stenosis, two had spinal epidural hematomas, one had an ossified herniated disc and three had soft herniated discs. None of the patients complained of significant pain at the initial presentation. All of the patients had a mild sensory deficit that was initially unrecognized. The pain of the patients began to become evident after hospitalization and, patients transferred to neurosurgery department. Cervical spinal pathologies compressing the corticospinal tract in one-half of the cervical spinal canal may present with only hemiparesis, without neck and radicular pain. If it's too late, permanent neurological damage may become inevitable while it is a correctable pathology.

  6. [Cervical myelopathy from an aspect of a neurological surgeon].

    Koyama, T

    1994-12-01

    More than 65 per cent of intramedurally tumors and intradural extramedurally tumors were located in cervical region. They enact a cause of cervical myelopathy. A special attention should be paid to solitaly intramedurally vascular malformations, when the patients show an acute progressive myelopathy. In very rare cases of syringomyelia, intramedurally tumors such as hemangioblastoma or ependymoma could be found, so that enhanced MRI or angiography should be done if necessary. In cases of a herniated disc, cervical spondylosis and OPLL, the distance between articulo-pillar line and spinolaminal line must be measured. If the distance of both lines is near or the same, that means narrow cervical canal. In rare cases the form of the vertebral body is round. This is a rare cause of a type of narrow canal.

    2016-06-01

    We aimed to investigate the diagnostic and therapeutic approaches in pharyngoesophageal perforation (PEP) following anterior cervical spine intervention (ACSI). We reviewed the records of four patients with PEP after ACSI. Symptoms, physical examination findings, imaging results, treatment, and follow-up characteristics were evaluated. All four patients had undergone ACSI for either cervical trauma or cervical disc herniation with cervical cage reconstruction. Symptoms developed within the first 10 days of the postoperative period in three patients, and in the eighth month in one patient. Mucosal defects were detected during neck exploration in three patients. Reconstruction with primary suture and a local muscle flap was utilized in two patients. Three patients were discharged 3-8 weeks after surgical treatment. In cases of PEP after ACSI, a good prognosis can be achieved when symptoms are detected in the early period and reconstruction with local muscle flap is applied.

    Full Text Available Ailiang Zhang, Kun Wang, Lianghua Ding, Xinnan Bao, Xuan Wang, Xubin Qiu, Jinbo Liu Spine Surgery, Third Affiliated Hospital of Soochow University, Changzhou, People’s Republic of China Abstract: Lumbar disc herniation (LDH is an important cause of radiculopathy, but the underlying mechanisms are incompletely understood. Many studies suggested that local inflammation, rather than mechanical compression, results in radiculopathy induced by LDH. On the molecular and cellular level, nuclear factor-kappa B (NF-κB and nucleotide-binding domain-like receptor protein 3 (NLRP3 inflammasome have been implicated in the regulation of neuroinflammation formation and progression. In this study, the autologous nucleus pulposus (NP was implanted in the left L5 dorsal root ganglion (DRG to mimic LDH in rats. We investigated the expression of NF-κB and the components of NLRP3 inflammasome in the DRG neurons in rats. Western blotting and immunofluorescence for the related molecules, including NLRP3, apoptosis-associated speck-like protein containing caspase-1 activator domain (ASC, caspase-1, interleukin (IL-1β, IL-18, IκBα, p-IκBα, p65, p-p65, and calcitonin gene-related peptide (CGRP were examined. In the NP-treated group, the activations of NLRP3, ASC, caspase-1, IL-1β, IL-18, p-IκBα, and p-p65 in DRG neurons in rats were elevated at 1 day after surgery, and the peak occurred at 7 days. Treatment with Bay11-7082, an inhibitor of the actions of IKK-β, was able to inhibit expression and activation of the molecules (NLRP3, ASC, caspase-1, IL-1β, IL-18, p-IκBα, and p-p65 and relieve the pain in rats. Our study shows that NF-κB and NLRP3 inflammasome are involved in the maintenance of NP-induced pain, and that Bay11-7082 could alleviate mechanical allodynia and thermal hyperalgesia by inhibiting NF-κB and NLRP3 inflammasome activation.

    anillo fibroso y núcleo pulposo. Se llevó a cabo un análisis semicuantitativo por microscopia óptica de las alteraciones histopatológicas. RESULTADO: Respecto a los parámetros evaluados en el análisis comparativo entre anillo fibroso y núcleo pulposo, no se produjo variación estadística significativa entre los grupos, lo cual muestra que ambas regiones son semejantes. La hernia extruida presentó una mayor proporción de infiltrado inflamatorio y neovascularización. Las alteraciones degenerativas no presentaron una variación significativa según el tipo de hernia. CONCLUSIONES: En la hernia discal hay una relación entre neovascularización, infiltrado inflamatorio y tipo de hernia. No hay diferencia histopatológica respecto a la parte del disco intervertebral analizada.OBJECTIVE: to investigate histopathological changes such as neovascularization, inflammatory infiltrate, cellularity, apoptosis, mucoid degeneration, granular changes, and calcification in contained and extruded disc herniations, and to compare these differences in the nucleus pulposus and annulus fibrosus. METHODS: 65 lumbar discs were evaluated. These were divided in three groups: 25 cases of extruded herniated discs, 28 cases of contained herniated discs, and 12 cases of discs without degenerative changes. Fragments were removed and separated into annulus fibrosus and nucleus pulposus. Semi-quantitative analysis of histopathologic changes was carried out, using a microscope. RESULTS: in the comparative analysis between annulus fibrosus and nucleus pulposus, no statistical differences were obtained between these groups, showing that both regions are similar. The extruded disc herniation presented a higher proportion of inflammatory infiltrate and neovascularization. Degenerative changes did not present significant variation in relation to disc herniation type. CONCLUSION: There is a relation in disc herniation between neovascularitazion, inflammatory infiltrate and type of disc herniation

    1987-01-01

    We report two cases of cervical disc disease with myelopathy classified as of motor system syndrome type showing small contrast accumulation within the spinal cord on delayed CT myelography. In our two cases, high density spots on delayed CT myelography were bilaterally localized within the spinal cord, and believed represent pathological changes of the spinal cord, such as collection of microcavities or cystic necrosis. In case 1, the high density areas seemed to be localized in the anterior horn and corticospinal tract, and in case 2, they seemed to be localized in the corticospinal tract. The patient in case 1 produced signs and symptoms resembling motor neurone disease and lesion could not be differentiated from the latter. Delayed CT myelography showed that the cause of the upper limb amyotrophy was attributed to an anterior horn disorder and that of pyramidal tract sign to a corticospinal tract disorder. Therefore, we could differentiate the lesion from motor neurone disease on delayed CT myelography in case 1. In conclusion, we emphasize that delayed CT myelography can demonstrate the intramedullary pathological changes in the cervical disc disease and is useful in distinguishing between cervical disc disease simulating motor neurone disease and the latter.

    Studies delineating the adjacent level effect of single level disc replacement systems have been reported in literature. The aim of this study was to compare the adjacent level biomechanics of bi-level disc replacement, bi-level fusion and a construct having adjoining level disc replacement and fusion system. In total, biomechanics of four models- intact, bi level disc replacement, bi level fusion and fusion plus disc replacement at adjoining levels- was studied to gain insight into the effects of various instrumentation systems on cranial and caudal adjacent levels using finite element analysis (73.6N+varying moment). The bi-level fusion models are more than twice as stiff as compared to the intact model during flexion-extension, lateral bending and axial rotation. Bi-level disc replacement model required moments lower than intact model (1.5Nm). Fusion plus disc replacement model required moment 10-25% more than intact model, except in extension. Adjacent level motions, facet loads and endplate stresses increased substantially in the bi-level fusion model. On the other hand, adjacent level motions, facet loads and endplate stresses were similar to intact for the bi-level disc replacement model. For the fusion plus disc replacement model, adjacent level motions, facet loads and endplate stresses were closer to intact model rather than the bi-level fusion model, except in extension. Based on our finite element analysis, fusion plus disc replacement procedure has less severe biomechanical effects on adjacent levels when compared to bi-level fusion procedure. Bi-level disc replacement procedure did not have any adverse mechanical effects on adjacent levels. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Suzileide Oliveira Costa

    2018-01-01

    Full Text Available Disk herniation (DH is a protrusion of the nucleus pulposus through the fibrous ring, arising because of trauma to the spine, which over time will damage the intervertebral discs. The objective of this work is to analyze the hydrotherapy effects on DH. It was done a descriptive analysis, with a bibliographic review on lumbar disc herniation, as well as its prevention measures, and developed and based on the analysis of scientific articles. Eleven articles were founded using the key-words disk herniation, physiotherapy and hydrotherapy on PubMed site. One of all obey to the inclusion propositions. In this way it concludes that the conservative treatment for lumbar disc herniation most indicated would be the hydrotherapy, because the physical properties of the water diminish the impact on the intervertebral discs due to the fluctuation causing a pain relief, thus providing a better quality of life to the patient.

    1995-01-01

    We reviewed 19 patients with cervical myelopathy treated with anterior decompression and fusion. Etiology of cervical myelopathy was cervical disc herniation (CDH) in 13 patients and cervical spondylosis (CSM) in 6. Clinical recovery rate (%) was calculated from preoperative cervical myelopathy score (JOA) and the score at follow-up. Correlation between the clinical recovery rate and MRI findings (area and flatness at the narrowest part of the spinal cord), age at surgery, duration of myelopathy and pre-operative clinical score were analyzed separately in the CDH and CSM groups. Clinical recovery rate averaged 69% in the CDH group and 75% in the CSM group. In the CDH group, average clinical recovery rate in patients younger than 60 years was 80 and in patients over 60 years was 60. There was a significant negative correlation between the clinical recovery rate and age at surgery (p<0.05). No significant correlation was found between the clinical recovery rate and other factors investigated. (author)

    2018-01-01

    Background Disorders connected with the musculoskeletal and central nervous system dysfunction are the most significant clinical problem worldwide. Our earlier research has shown that back and spinal disorders and lumbar disc disorders were most frequently diagnosed using MRI scanner at the University Clinical Hospital (UCH) in Olsztyn in years 2011–2015. We have also observed that another two diseases of spinal column, spondylosis and cervical disc disorders, were also very prevalent. The main objective of this work was to analyze the prevalence of spondylosis and cervical disc disorders in the study population diagnosed at UCH in years 2011–2015. Methods The digital database including patients' diagnostic and demographic information was generated based on MRI reports from years 2011–2015 and analyzed using SPSS software. Results Within the study group (n = 13298) the most frequently MRI-diagnosed diseases were musculoskeletal group (M00–M99; n = 7711; 57,98%) and cervical disc disorders (M50; n = 1659; 12,47%) and spondylosis (M47, n = 611; 4,59%). More women (67%) than men (33%) were enrolled in the study, and the largest fraction of the study population was in the range of 51–60 years, with about 1/3 of cases of both diseases diagnosed in early age range of 31–40 years. Conclusion Significant number of patients presenting with either of the spine disorders at the young age of 31–40 years points to the necessity of introducing methods preventing disorders of the vertebral column at younger age, preferably at school age.

    1992-01-01

    To obtain functional studies of the cervical spine, a device has been developed which allows MRI examinations to be carried out in five different degrees of flexion. T 1 and T 2 * weighted FFE sequences were used. Dynamic functional MRI was performed on 5 normals and 31 patients (5 disc herniation, 4 whiplash injuries, 6 spinal canal stenoses, 14 laminectomies and spinal fusions, 2 rheumatoid arthritis). The relationship of the spinal cord to the bony and ligamentous components in different degrees of flexion was particularly well shown in whiplash injury, spinal stenosis and postoperative situations.

    2012-01-01

    Full Text Available The purpose of this study was to investigate whether treatment with electroacupuncture (EA inhibited mitochondria-dependent apoptosis in annulus fibrosis (AF cells in a rat model of cervical intervertebral disc degradation induced by unbalanced dynamic and static forces. Forty Sprague-Dawley rats were used in this study, of which 30 underwent surgery to induce cervical intervertebral disc degradation, 10 rats received EA at acupoints Dazhui (DU 14 and Shousanli (LI 10. TUNEL staining was measured to assess apoptosis in AF cells, immunohistochemistry was used to examine Bcl-2 and Bax expression, colorimetric assays were used to determine caspase 9 and caspase 3 activities and RT-PCR and western blotting were used to assess the mRNA and protein expression of Crk and ERK2. Treatment with EA reduced the number of AF-positive cells in TUNEL staining, increased Bcl-2-positive cells and decreased Bax-positive cells in immunohistochemical staining, significantly inhibited the activation of caspases-9 and -3, and enhanced the mRNA and protein expression of Crk and ERK2. Our data show that EA inhibits AF cell apoptosis via the mitochondria-dependent pathway and up-regulates Crk and ERK2 expression. These results suggest that treatment with may be a good alternative therapy for preventing cervical spondylosis.

    2003-01-01

    Background: Cervical spine and intervertebral discs are potentially prone to functional disorders. Objectives: This study sought type and distribution of different pathologies in the cervical spine and a possible relationship between the MRI findings and the probable risk factors of the degenerative disorders. Materials and Methods: This descriptive cross-sectional research was carried out from october 2000 to january 2002 in three referral centers in Tehran. All the patients had referred for cervical MRI for neck pain and/or radicular pain. Results: Totally 342 patients entered the study. Sixty percent of patients were male. The mean age was 55.1± 12.1 years. Seventy-nine percent of patients had abnormal MRI findings (238 patients (70%) had signs of degenerative processes and 31 patients (9%) had the other findings ) with a total 308 pathologies. The most common findings were disc bulging /protrusion (%21.1), disc dehydration (%20.1), disc herniation (%18.1), and canal stenosis (%17.5). Older age, male gender and history of neck trauma were associated with increasing probability of degenerative changes (P-values<0.05). Conclusion: Types of cervical spine pathologies are comparable to other reports. The anatomical distribution of disc bulging and protrusion in our study are similar to other reports. Likewise age, gender and a history of trauma the neck were closely associated with the degenerative signs on the MR images

    Full Text Available OBJECTIVE: The objective of this study was to evaluate the efficacy of quantitative T2 magnetic resonance imaging (MRI for quantifying early cervical intervertebral disc (IVD degeneration in asymptomatic young adults by correlating the T2 value with Pfirrmann grade, sex, and anatomic level. METHODS: Seventy asymptomatic young subjects (34 men and 36 women; mean age, 22.80±2.11 yr; range, 18-25 years underwent 3.0-T MRI to obtain morphological data (one T1-fast spin echo (FSE and three-plane T2-FSE, used to assign a Pfirrmann grade (I-V and for T2 mapping (multi-echo spin echo. T2 values in the nucleus pulposus (NP, n = 350 and anulus fibrosus (AF, n = 700 were obtained. Differences in T2 values between sexes and anatomic level were evaluated, and linear correlation analysis of T2 values versus degenerative grade was conducted. FINDINGS: Cervical IVDs of healthy young adults were commonly determined to be at Pfirrmann grades I and II. T2 values of NPs were significantly higher than those of AF at all anatomic levels (P0.05. T2 values decreased linearly with degenerative grade. Linear correlation analysis revealed a strong negative association between the Pfirrmann grade and the T2 values of the NP (P = 0.000 but not the T2 values of the AF (P = 0.854. However, non-degenerated discs (Pfirrmann grades I and II showed a wide range of T2 relaxation time. T2 values according to disc degeneration level classification were as follows: grade I (>62.03 ms, grade II (54.60-62.03 ms, grade III (<54.60 ms. CONCLUSIONS: T2 quantitation provides a more sensitive and robust approach for detecting and characterizing the early stage of cervical IVD degeneration and to create a reliable quantitative in healthy young adults.

  4. Comparison among perfect-C®, zero-P®, and plates with a cage in single-level cervical degenerative disc disease.

    Noh, Sung Hyun; Zhang, Ho Yeol

    2018-01-25

    We intended to analyze the efficacy of a new integrated cage and plate device called Perfect-C for anterior cervical discectomy and fusion (ACDF) to cure single-level cervical degenerative disc disease. We enrolled 148 patients who were subjected to single-level ACDF with one of the following three surgical devices: a Perfect-C implant (41 patients), a Zero-P implant (36 patients), or a titanium plate with a polyetheretherketone (PEEK) cage (71 patients). We conducted a retrospective study to compare the clinical and radiological results among the three groups. The length of the operation, intraoperative blood loss, and duration of hospitalization were significantly lower in the Perfect-C group than in the Zero-P and plate-with-cage groups (P Zero-P groups but was noted in 21 cases (30%) in the plate-with-cage group. The cephalad and caudal plate-to-disc distance (PDD) and the cephalad and caudal PDD/anterior body height (ABH) were significantly greater in the Perfect-C and Zero-P groups than in the plate-with-cage group (P Zero-P group, and in 15 cases (21%) in the plate-with-cage group. Fusion occurred in 37 cases (90%) in the Perfect-C group, in 31 cases (86%) in the Zero-P group, and in 68 cases (95%) in the plate-with-cage group. The Perfect-C, Zero-P, and plate-with-cage devices are effective for treating single-level cervical degenerative disc disease. However, the Perfect-C implant has many advantages over both the Zero-P implant and conventional plate-cage treatments. The Perfect-C implant was associated with shorter operation times and hospitalization durations, less blood loss, and lower subsidence rates compared with the Zero-P implant or the titanium plate with a PEEK cage.

    2013-10-01

    Cervical disc prostheses induce significant amount of artifact in magnetic resonance imaging which may complicate radiologic follow-up after surgery. The purpose of this study was to investigate as to what extent the artifact, induced by the frequently used Discover(®) cervical disc prosthesis, impedes interpretation of the MR images at operated and adjacent levels in 1.5 and 3 Tesla MR. Ten subsequent patients were investigated in both 1.5 and 3 Tesla MR with standard image sequences one year following anterior cervical discectomy with arthroplasty. Two neuroradiologists evaluated the images by consensus. Emphasis was made on signal changes in medulla at all levels and visualization of root canals at operated and adjacent levels. A "blur artifact ratio" was calculated and defined as the height of the artifact on T1 sagittal images related to the operated level. The artifacts induced in 1.5 and 3 Tesla MR were of entirely different character and evaluation of the spinal cord at operated level was impossible in both magnets. Artifacts also made the root canals difficult to assess at operated level and more pronounced in the 3 Tesla MR. At the adjacent levels however, the spinal cord and root canals were completely visualized in all patients. The "blur artifact" induced at operated level was also more pronounced in the 3 Tesla MR. The artifact induced by the Discover(®) titanium disc prosthesis in both 1.5 and 3 Tesla MR, makes interpretation of the spinal cord impossible and visualization of the root canals difficult at operated level. Adjusting the MR sequences to produce the least amount of artifact is important.

    Purpose: We examined the postoperative changes of the cervical spine after treatment of cervical nerve root compression with anterior cervical discectomy and fusion with a new titanium intervertebral disc. Patients and Methods: 37 patients were examined prior to, as well as 4 days, 6 weeks, and 7 months after surgery. Lateral view X-rays and functional imaging were used to evaluate posture and mobility of the cervical spine, the position of the implants, and the reactions of adjacent bone structures. Results: Implantation of the titanium disc led to post-operative distraction of the intervertebral space and slight lordosis. Within the first 6 months a slight loss of distraction and re-kyphosis due to impression of the implants into the vertebral end-plates were found in all patients. We noted partial infractions into the vertebral end-plates in 10/42 segments and slight mobility of the implants in 14/42 segments. Both groups of patients showed reactive spondylosis and local symptoms due to loosening of the implants. The pain subsided after onset of bone bridging and stable fixation of the loosened discs. Conclusions: The titanium intervertebral disc provides initial distraction of the fusioned segments with partial recurrence of kyphosis during the subsequent course. Loosening of the implants with local symptoms can be evaluated with follow-up X-rays and functional imaging. (orig.)

    Several previous studies comparing artificial disc replacement (ADR) and fusion have been conducted with cautiously positive results in favor of ADR. This study is not, in contrast to most previous studies, an investigational device exemption study required by the Food and Drug Administration for approval to market the product in the United States. This study was partially funded with unrestricted institutional research grants by the company marketing the artificial disc used in this study. To compare outcomes between the concepts of an artificial disc to treatment with anterior cervical decompression and fusion (ACDF) and to register complications associated to the two treatments during a follow-up time of 2 years. This is a randomized controlled multicenter trial, including three spine centers in Sweden. The study included patients seeking care for cervical radiculopathy who fulfilled inclusion criteria. In total, 153 patients were included. Self-assessment with Neck Disability Index (NDI) as a primary outcome variable and EQ-5D and visual analog scale as secondary outcome variables. Patients were randomly allocated to either treatment with the Depuy Discover artificial disc or fusion with iliac crest bone graft and plating. Randomization was blinded to both patient and caregivers until time for implantation. Adverse events, complications, and revision surgery were registered as well as loss of follow-up. Data were available in 137 (91%) of the included and initially treated patients. Both groups improved significantly after surgery. NDI changed from 63.1 to 39.8 in an intention-to-treat analysis. No statistically significant difference between the ADR and the ACDF groups could be demonstrated with NDI values of 39.1 and 40.1, respectively. Nor in secondary outcome measures (EQ-5D and visual analog scale) could any statistically significant differences be demonstrated between the groups. Nine patients in the ADR group and three in the fusion group underwent

  11. Bilateral cervical spondylolysis of C7.

    Paik, Nam Chull

    2010-11-01

    Cervical spondylolysis, which is defined as a cleft between the superior and inferior articular facets of the articular pillar, is a rare condition. The sixth cervical vertebra (C6) is the level most commonly affected. Cases involving C2, C3, C4, or C5 have also been reported. However, to date, no case of C7 spondylolysis has been reported. To present a rare case of bilateral spondylolysis of the seventh cervical vertebra (C7) in a 58-year-old man. A case report. A 58-year-old man visited our hospital with chronic posterior neck pain radiating to the left upper extremity. Magnetic resonance imaging (MRI) study revealed left foraminal disc herniations at C5-C6 and C6-C7. Cervical spondylolysis involving C7 was discovered incidentally during computed tomography (CT)-guided transforaminal steroid injection. Plain radiographs, CT images, and MRIs were reviewed thoroughly once again. The patient's symptoms were relieved after he received CT-guided transforaminal steroid injections. Plain radiographs revealed a radiolucent defect in the articular pillar and cleft at the spinous process of C7. Computed tomography confirmed bilateral spondylolysis and spina bifida occulta of the C7 vertebra. Magnetic resonance imaging revealed absence of edema, which was suggestive of a chronic lesion. Involvement of C7 is not exceptional in a case of cervical spondylolysis. Copyright © 2010 Elsevier Inc. All rights reserved.

    The objective of this study was to compare the clinical outcomes of the cervical interlaminar epidural steroid injection (CIESI) for unilateral radiculopathy by the midline or paramedian approaches and to determine the prognostic factors of CIESI. We retrospectively analyzed 182 patients who underwent CIESI from January 2009 to December 2012. Inclusion criteria were no previous spinal steroid injection, presence of a cross-sectional image, and presence of follow-up records. Exclusion criteria were patients with bilateral cervical radiculopathy and/or dominant cervical axial pain, combined peripheral neuropathy, and previous cervical spine surgery. Short-term clinical outcomes were evaluated at the first follow-up after CIESI. We compared the clinical outcomes between the midline and paramedian approaches. Possible prognostic factors for the outcome, such as age, gender, duration of radiculopathy, and cause of radiculopathy were also analyzed. Cervical interlaminar epidural steroid injections were effective in 124 of 182 patients (68.1%) at the first follow-up. There was no significant difference in the clinical outcomes of CIESI, between midline (69.6%) and paramedian (63.7%) approaches (p = 0.723). Cause of radiculopathy was the only significant factor affecting the efficacy of CIESI. Patients with disc herniation had significantly better results than patients with neural foraminal stenosis (82.9% vs. 56.0%) (p < 0.001). There is no significant difference in treatment efficacy between the midline and paramedian approaches in CIESI, for unilateral radiculopathy. The cause of the radiculopathy is significantly associated with the treatment efficacy; patients with disc herniation experience better pain relief than those with neural foraminal stenosis.

Patients with disc herniation had significantly better results than patients with neural foraminal stenosis (82.9% vs. 56.0%) (p < 0.001). There is no significant difference in treatment efficacy between the midline and paramedian approaches in CIESI, for unilateral radiculopathy. The cause of the radiculopathy is significantly associated with the treatment efficacy; patients with disc herniation experience better pain relief than those with neural foraminal stenosis.

    Compared with anterior cervical discectomy and fusion (ACDF), cervical disc replacement (CDR) has provided satisfactory clinical results. The incidence of post-operative dysphagia between ACDF with a traditional anterior plate and CDR remains controversial. Considering the limited studies and knowledge in this area, a retrospective study focusing on post-operative dysphagia was conducted. The Bazaz grading system was used to assess the severity of dysphagia at post-operative intervals including 1 week, 1 month, 3 months, 6 months, 12 months and 24 months respectively. The Chi-square test, Student t-test, Mann-Whitney U tests and Ordinal Logistic regression were used for data analysis when appropriate. Statistical significance was accepted at a probability value of dysphagia in the CDR and plate group were 36.58% and 60.43% at one week, 29.27% and 38.85% at one month, 21.95% and 31.65% at three months, 6.83% and 17.99% at six months, 5.85% and 14.39% at 12 months, and 4.39% and 10.07% at the final follow-up respectively (All Pdysphagia (all Pdysphagia. Female patients, two-level surgery, C4/5 surgery and anterior cervical plating were associated with a higher incidence of dysphagia. Future prospective, randomized, controlled studies are needed to further validate these findings. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Introduction: Lumbar disc prolapse is most common between 30 and 50 years of age and is associated with severe disability and pain. It commonly occurs at L4/5 and L5/S1. Transforaminal endoscopic discectomy is an emerging technique for treatment of degenerative disc disease. Literature has shown clinical outcomes, comparable to classical open and micro lumbar discectomy. Central disc herniations in lumbar spine pose technical challenge for transforaminal endoscopic decompression due to its location. Existing techniques to access central herniations and ventral epidural space have trajectory related challenges due to the proximity of the retroperitoneal space and abdominal organs and technically difficult for the less experienced surgeon. Materials and Methods: Thirty patients – 19 males and 11 females – with central, multifocal, central-paracentral disc herniations in the lumbar spine operated in 2015 and 2016 were considered in this study. All patients underwent selective endoscopic discectomy under monitored care anesthesia and local anesthesia with modification of the classical technique, medialization of annulotomy, undercutting the nonarticular part of superior articular process (foraminotomy and use of articulating and long jaw instruments either alone or in combination. Results: In all the thirty patients, we were able to achieve adequate decompression with neurological recovery. All patients improved in their neurological status. Postoperatively, visual analog scale dropped from 7.8 to 1.8 and ODI dropped from 73.46% to 32. 90% of the patients reported excellent and good results. One patient had recurrent herniation and was treated with transforaminal surgery. One patient had persistent back pain and reported poor outcome. Three patients underwent medial branch block for facet joint pain followed by medial branch rhizotomy and reported excellent and good results. Conclusion: Transforaminal endoscopic spine surgery with modifications

    To evaluate injury patterns of facet joints and associated soft tissue injuries in patients with acute traumatic cervical facet joint injuries. From among patients with cervical spine trauma, 27 with facet joint injuries, as seen on CT and MRI, were chosen for this study. CT scans were analyzed with regard to the location of facet joint injury, the presence or absence of facet dislocation or fracture, and other associated fractures. MR images were analyzed with regard to ligament injury, intervertebral disc injury, intervertebral disc herniation, and spinal cord injury. The most common location of facet joint injury was C6-7 level(n=10), followed by C5-6(n=8). Among these 27 patients with facet joint injuries, 12(44%) had bilateral injuries and 15(56%) unilateral injuries. Facet fractures were present in 17 cases(63%) and the fracture of inferior facet was more frequent than superior. Patterns of fracture were vertical, transverse, or comminuted, but vertical fracture was the most common. Various degrees of dislocation were observed in patients with facet fractures. Fractures other than facet included pillar(n=11), lamina(n=6), transverse process(n=14), body(n=13), and spinous process(n=3). On MR images, anterior longitudinal ligament injury was found in 8 patients(30%), posterior longitudinal ligament injury in 4(15%), and interspinous ligament injury in 20(74%). Twelve patients(44%) had spinal cord injuries including edema(n=8) and hemorrhage(n=4). Among patients with disc abnormalities, 11(41%) had intervertebral disc injuries, and traumatic disc herniations were found in nine. Traumatic cervical facet joint injuries were manifested as various patterns and frequently associated with other fractures or soft tissue injuries. Analysis of CT and MR findings of these injury patterns helped formulate a therapeutic plan and determine of prognosis.

From January 2011 to January 2014,50 patients were treated with the MC+PEEK cage filled with autogenous cancellous illic-bone graft after anterior cervical discectomy. There were 22 patients with cervical spondylosis,26 patients with traumatic cervical disc herniation, 2 patients with cervical instability in these patients. There were 32 males and 18 females, aged from 30 to 79 years old with an average of 53.30 years old. There were 32 patients with single segment, 15 patients with double segments and 3 patients with three segments. Cervical AP and lateral and the flexion-extension X-rays were regularly taken in order to assess the cervical physiological curvature, the graft fusion and internal fixation related complications. Nerve function, clinical effect and bone fusion were respectively evaluated according to Japan Orthopedic Association (JOA), Otani grade and Suk method. All patients were followed up from 6 to 36 months with an average of 20 months. No correlated surgical complications were found and all patients obtained bony fusion with an average time of 4.30 months. JOA score had significantly improvement after surgery (P cervical fusion can obtain satisfactory clinical effect with less operation injury and reduce the complications. It is a better fusion method in anterior cervical fusion.

    To obtain functional studies of the cervical spine, a device has been developed which allows MRI examinations to be carried out in five different degrees of flexion. T[sub 1] and T[sub 2][sup *] weighted FFE sequences were used. Dynamic functional MRI was performed on 5 normals and 31 patients (5 disc herniation, 4 whiplash injuries, 6 spinal canal stenoses, 14 laminectomies and spinal fusions, 2 rheumatoid arthritis). The relationship of the spinal cord to the bony and ligamentous components in different degrees of flexion was particularly well shown in whiplash injury, spinal stenosis and postoperative situations.

    We report a cervical intraspinal cyst in a dog that was initially tetraparetic but spontaneously recovered completely. MRI revealed a well-demarcated intraspinal cyst located dorsally to a degenerated intervertebral disc. The location of the cyst and its signal features on MRI resembled those of discal cysts previously reported in humans. It has been reported in dogs that clinical signs of a intraspinal cyst are similar to those of intervertebral disc herniation and both conditions require surgical intervention. Unexpectedly, our case showed rapid spontaneous recovery and the follow-up MRI revealed complete resolution of the intraspinal cyst and spinal cord compression. Spontaneous recovery of degenerative intraspinal cyst may occur in dogs, similar to rare human cases as reported previously. (author)

    To describe and characterize the temporal changes in disc-related disorders of the thoracic spine using MR imaging. A retrospective longitudinal cohort study was carried out of 40 patients with two sequential thoracic spine MR images at variable intervals. The images were assessed for baseline presence of, new incidence of and changes in disc herniation, degenerative disc disease, endplate marrow signal alteration and Schmorl nodes. The range of follow-up was 4-149 weeks. Baseline presence was: disc herniation, 10% (49/480); degenerative disc disease, 14% (66/480); endplate marrow signal alteration, 2.3% (11/480); Schmorl nodes 9.6% (46/480). Most pre-existing lesions tended to remain unchanged. Herniations showed the most change, tending to improve in 27%. New incidence was: disc herniation, 1.5% (7/480), degenerative disc disease, 2% (10/480); endplate marrow signal alteration, 1.6% (8/480); Schmorl nodes, 2.1% (10/480). Disc degeneration was first visible at an 11-week interval and once established almost never changed over many weeks to months. Endplate signal alterations (Modic changes) were uncommon. Schmorl nodes show no change from baseline for up to 2 1/2 years. All findings predominated in the lower intervertebral levels from T6 to T10. The most prevalent thoracic spine disc-related findings are degeneration and herniation. Disc herniations predominate in the lower segments and are a dynamic phenomenon. Disc degeneration can be rapidly evolving but tends to remain unchanged after occurrence. Endplate marrow signal changes were an uncommon manifestation of thoracic disc disease. Schmorl nodes showed the least change over time. (orig.)

    CoCrMo alloys are believed to be a kind of potential material for artificial cervical disc. However, the tribological properties of CoCrMo alloys against different metals and ceramics are not systematically studied. In this study, the tribological behaviors of CoCrMo alloys against metals (316L, Ti6Al4V) and ceramics (Si3N4, ZrO2) were focused under dry friction and 25 wt.% newborn calf serum (NCS)-lubricated conditions using a ball-on-disc apparatus under reciprocating motion. The microstructure, composition and hardness of CoCrMo alloys were characterized using x-ray diffraction, scanning electron microscopy (SEM) and hardness testers, respectively. The contact angles of the CoCrMo alloys with deionized water and 25 wt.% NCS were measured by the OCA contact angle measuring instrument. The maximum wear width, wear depth and wear volume were measured by three-dimensional white light interference. The morphology and the EDX analysis of the wear marks on CoCrMo alloys were examined by SEM to determine the basic mechanism of friction and wear. The dominant wear mechanism in dry friction for CoCrMo alloys against all pairings was severe abrasive wear, accompanied with a lot of material transfer. Under 25 wt.% NCS-lubricated condition, the wear mechanism for CoCrMo alloys against ceramics (Si3N4, ZrO2) was also mainly severe abrasive wear. However, severe abrasive wear and electrochemical corrosion occurred for the CoCrMo-316L pairing under lubrication. Severe abrasive wear, adhesive wear and electrochemical corrosion occurred for the CoCrMo-Ti6Al4V pairing under lubrication. According to the results, the tribological properties of CoCrMo alloys against ceramics were better than those against metals. The CoCrMo-ZrO2 pairing displayed the best tribological behaviors and could be taken as a potential candidate bearing material for artificial cervical disc.

    Polyetheretherketone (PEEK) and its composite coatings are believed to be the potential candidates' bio-implant materials. However, these coatings have not yet been used on the surface of titanium-based orthopedics and joint products and very few investigations on the tribological characteristics could be found in the published literature till date. In this study, the wettabilities, composition and micro-hardness were characterized using contact angle measurement, scanning electron microscopy (SEM) and hardness tester. The tribological tests were conducted using a ball-on-disc contact pair under 25% newborn calf serum (NCS) lubricated condition. For comparison, bare Ti6Al4V was studied. The obtained results revealed that those PEEK/ZrO 2 composite coatings could improve the tribological properties of Ti6Al4V significantly. Adhesive wear and mild abrasive wear might be the dominant wear and failure mechanisms for PEEK/ZrO 2 composite coatings in NCS lubricated condition. After comprehensive evaluation in the present study, 5 wt.% ZrO 2 nanoparticles filled PEEK coating displayed the optimum tribological characteristics and could be taken as a potential candidate for the bearing material of artificial cervical disc. - Graphical abstract: Polyetheretherketone (PEEK) is a type of biomaterial which might be used in surface modification.

    Anterior cervical discectomy and fusion (ACDF) constitutes the conventional treatment of cervical disc herniation due to degenerative disc disease (DDD). ACDF with plating presents a variety of complications postoperatively and stand-alone cages are thought to be a promising alternative. The aim of this study was firstly, to analyze prospectively collected data from a sample of patients treated with single ACDF using C-Plus self-locking stand-alone PEEK cage system, without the use of plates or screws, in order to evaluate pain levels of patients, utilizing Neck and Arm Pain scale as an expression of visual analogue scale (VAS). Secondly, we aimed to evaluate health-related quality of life, via the short-form 36 (SF-36) and Neck Disability Index (NDI). Thirty-six patients (19 male and 17 female) with mean age 49.6±7 years old who underwent successful single ACDF using self-locking stand-alone PEEK cage for symptomatic cervical DDD were selected for the study. Neck and Arm pain, as well as SF-36 and NDI were estimated preoperatively and 1, 3, 6, and 12 months postoperatively. Patients underwent preoperative and postoperative clinical, neurological and radiological evaluation. The clinical and radiological outcomes were satisfactory after a minimum 1-year follow-up. All results were statistically important (P<0.05), excluding improvement in NDI measured between 6 and 12 months. SF-36, Neck Pain, as well as Arm Pain featured gradual and constant improvement during follow-up, with best scores presenting at 12 months after surgery, while NDI reached its best at 6 months postoperatively. Generally, all scores showed improvement postoperatively during the different phases of the follow-up. Subsequently, ACDF using C-Plus cervical cage constitutes an effective method for cervical disc herniation treatment, in terms of postoperative improvement on pain levels and health-related quality of life and a safe alternative to the conventional method of treatment for cervical DDD.

    2008-01-01

    Objective: To present the prevalence and imaging findings of patients with hydatid disease (HD) showing features of migration or herniation of the hydatid cysts (HCs) and underline the clinical significance of this condition. Materials and methods: Between May 2003 and June 2006, 212 patients with HD were diagnosed by abdomen and/or thorax CT, searched for migrating or herniating HC. Imaging findings of 7 patients (5 women, 2 men with an age range of 19-63 years; mean ± S.D., 44 ± 19 years) with HD showing transdiaphragmatic migration (6 subjects) or femoral herniation (1 subject) were evaluated. Diagnosis of all the patients were established by pathologic examination and migration or herniation was confirmed by surgery in all patients. Results: Liver HD were identified in 169 (79.7%) of 212 patients with HD. Transdiaphragmatic migration of HCs were identified in 6 (3.5%) of the 169 patients with liver HD. In one patient, femoral herniation of the retroperitoneal HC into the proximal anterior thigh was identified. All of these seven patients exhibiting migration or herniation of HCs had active HCs including 'daughter cysts'. Two patients had previous surgery because of liver HD and any supradiaphragmatic lesion was not noted before operation. Findings of migration or herniation were confirmed by surgery. Conclusion: Active HCs may show migration or herniation due to pressure difference between the anatomic cavities, and in some of the patients, by contribution of gravity. Previous surgery may be a complementary factor for migration as seen in two of our patients. The possibility of migration or herniation in patients with HD should be considered before surgery

    The authors put-forth this technical report to establish the feasibility of performing an anterior cervical corpectomy and fusion (ACCF) and a two-level anterior cervical discectomy and fusion (ACDF) using a minimally invasive approach with tubular retractors. First case: cervical spondylotic myelopathy secondary to a large postero-inferiorly migrated disc treated with corpectomy and reconstruction with a mesh cage and locking plate. Second case: cervical disc herniation with radiculopathy treated with a two-level ACDF. Both cases were operated with minimally invasive approach with tubular retractor using a single incision. Technical aspects and clinical outcomes have been reported. No intra or post-operative complications were encountered. Intra-operative blood loss was negligible. The patients had a cosmetic scar on healing. Standard procedure of placement of tubular retractors is sufficient for adequate surgical exposure with minimal invasiveness. Minimally invasive approach to anterior cervical spine with tubular retractors is feasible. This is the first report on use of minimally invasive approach for ACCF and two-level ACDF.

    1988-01-01

    From a series of 25 patients with low-back pain and sciatica who subsequently underwent surgical exploration, 24 lumbar herniated disks and one asymmetrically bulging disk were correctly diagnosed with use of a 0.5-T MR imaging unit. The radiologic findings on saggital images included a polypoid protrusion beyond the posterior margin of the vertebral bodies more clearly displayed with T1-weighted than with T-2 weighted sequences and a focal extension into the extradural space on axial views. In most, the signal intensity of HNP was isointense to the disk of origin. The study suggests that MR imaging is currently capable of accurately predicting an HNP. The diagnosis is based primarily on morphologic characteristics rather than signal intensity alterations

We conducted a cross-sectional study to assess predictive factors, especially Modic changes (MCs), associated with the intensity and duration of neck pain in patients with cervical disc degenerative disease.We retrospectively reviewed patients in our hospital from January 2013 to December 2016. Severe neck pain (SNP) and persistent neck pain (PNP) were the 2 main outcomes, and were assessed based on the numerical rating scale (NRS). Basic data, and also imaging data, were collected and analyzed as potential predictive factors. Univariate analysis and multiple logistic regression analysis were performed to assess the predictive factors for neck pain.In all, 381 patients (193 males and 188 females) with cervical degenerative disease were included in our study. The number of patients with SNP and PNP were 94 (24.67%) and 109 (28.61%), respectively. The NRS of neck pain in patients with type 1 MCs was significantly higher than type 2 MCs (4.8 ± 0.9 vs 3.9 ± 1.1; P = .004). The multivariate logistic analysis showed that kyphosis curvature (odds ratio [OR] 1.082, 95% confidence interval [CI] 1.044-1.112), spondylolisthesis (OR 1.339, 95% CI 1.226-1.462), and annular tear (OR 1.188, 95% CI 1.021-1.382) were factors associated with SNP, whereas kyphosis curvature (OR 1.568, 95% CI 1.022-2.394), spondylolisthesis (OR 1.486, 95% CI 1.082-2.041), and MCs (OR 1.152, 95% CI 1.074-1.234) were associated with PNP.We concluded that kyphosis curvature, spondylolisthesis, and annular tear are associated with SNP, whereas kyphosis curvature, spondylolisthesis, and MCs are associated with PNP. This study supports the view that MCs can lead to a long duration of neck pain.

    After single intradiscal injection of C-ABC in rabbit inter-vertebral discs, water content in the matrix of nucleus pulposus diminished clearly. After similar injection of C-ABC in sheep discs, disc inner pressure was diminished. After single intradiscal injection of C-ABC in dog inter-vertebral discs suffering disc herniation, the syndromes coming from the herniation diminished or disappeared. Based on these observations C-ABC is expected to be a chemonucleolytic agent and a human clinical trial is now in progress.

    Although the normal adult human intervertebral disc is considered to be avascular, vascularised cellular fibrous tissue can be found in pathological conditions involving the disc such as disc herniation. Whether lymphatics vessels form a component of this reparative tissue is not known as the presence or absence of lymphatics in herniated and normal disc tissue is not known. We examined spinal tissues and discectomy specimens for the presence of lymphatics. The examination used immunohistochemistry to identify the specific lymphatic endothelial cell markers, podoplanin and LYVE1. Lymphatic vessels were not found in the nucleus pulposus or annulus fibrosus of intact, non-herniated lumbar and thoracic discs but were present in the surrounding ligaments. Ingrowth of fibrous tissue was seen in 73% of herniated disc specimens of which 36% contained LYVE1+/podoplanin + lymphatic vessels. Lymphatic vessels were not seen in the sacrum and coccyx or biopsies of four sacrococcygeal chordomas, but they were noted in surrounding extra-osseous fat and fibrous tissue at the edge of the infiltrating tumour. Our findings indicate that lymphatic vessels are not present in the normal adult intervertebral disc but that, when there is extrusion of disc material into surrounding soft tissue, there is ingrowth of reparative fibrous tissue containing lymphatic vessels. Our findings also indicate that chordoma, a tumour of notochordal origin, spreads to regional lymph nodes via lymphatics in para-spinal soft tissues. (orig.)

  17. The course of atlanto-axial involvement and disc narrowing of the cervical spine in rheumatoid arthritis

    Carvalho, A. de; Graudal, H.; Aarhus Univ.

    1981-01-01

    In 188 patients with rheumatoid arthritis 585 radiological examinations of the cervical spine were performed. Subluxation of C1-2 was found more often than expected; it was often the only radiological change in that segment, and its degree was not related to the duration of the disease. Lateral radiographs taken in full flexion were important for the diagnosis. Age over 40 years at the onset of RA, increased ESR at least on one occasion and seropositivity were related to more severe degrees of involvement. The presence of subcutaneous nodules, high titres of the Rose-Waaler reaction and the presence of antinuclear antibodies had no definite relation to the degree of involvement. (orig.) [de

  18. Anterior cervical discectomy with fusion in patients with cervical disc degeneration: a prospective outcome study of 258 patients (181 fused with autologous bone graft and 77 fused with a PEEK cage)

    2010-01-01

    Background Anterior cervical discectomy with fusion (ACDF) is challenging with respect to both patient selection and choice of surgical procedure. The aim of this study was to evaluate the clinical outcome of ACDF, with respect to both patient selection and choice of surgical procedure: fusion with an autologous iliac crest graft (AICG) versus fusion with an artificial cage made of polyetheretherketone (PEEK). Methods This was a non-randomized prospective single-center outcome study of 258 patients who underwent ACDF for cervical disc degeneration (CDD). Fusion was attained with either tricortical AICG or PEEK cages without additional anterior plating, with treatment selected at surgeon's discretion. Radicular pain, neck-pain, headache and patient satisfaction with the treatment were scored using the visual analogue scale (VAS). Results The median age was 47.5 (28.3-82.8) years, and 44% of patients were female. 59% had single-level ACDF, 40% had two level ACDF and 1% had three-level ACDF. Of the patients, 181 were fused with AICG and 77 with a PEEK-cage. After surgery, the patients showed a significant reduction in radicular pain (ΔVAS = 3.05), neck pain (ΔVAS = 2.30) and headache (ΔVAS = 0.55). Six months after surgery, 48% of patients had returned to work: however 24% were still receiving workers' compensation. Using univariate and multivariate analyses we found that high preoperative pain intensity was significantly associated with a decrease in pain intensity after surgery, for all three pain categories. There were no significant correlations between pain relief and the following patient characteristics: fusion method (AICG or PEEK-cage), sex, age, number of levels fused, disc level fused, previous neck surgery (except for neck pain), previous neck trauma, or preoperative symptom duration. Two hundred out of the 256 (78%) patients evaluated the surgical result as successful. Only 27/256 (11%) classified the surgical result as a failure. Patient satisfaction

  2. Cervical Spondylosis and Hypertension

    2015-01-01

    Abstract Cervical spondylosis and hypertension are all common diseases, but the relationship between them has never been studied. Patients with cervical spondylosis are often accompanied with vertigo. Anterior cervical discectomy and fusion is an effective method of treatment for cervical spondylosis with cervical vertigo that is unresponsive to conservative therapy. We report 2 patients of cervical spondylosis with concomitant cervical vertigo and hypertension who were treated successfully with anterior cervical discectomy and fusion. Stimulation of sympathetic nerve fibers in pathologically degenerative disc could produce sympathetic excitation, and induce a sympathetic reflex to cause cervical vertigo and hypertension. In addition, chronic neck pain could contribute to hypertension development through sympathetic arousal and failure of normal homeostatic pain regulatory mechanisms. Cervical spondylosis may be one of the causes of secondary hypertension. Early treatment for resolution of symptoms of cervical spondylosis may have a beneficial impact on cardiovascular disease risk in patients with cervical spondylosis. PMID:25761188

    A randomized, double-blind, active-controlled trial. To assess the effectiveness of cervical interlaminar epidural injections of local anesthetic with or without steroids for the management of axial or discogenic pain in patients without disc herniation, radiculitis, or facet joint pain. Cervical discogenic pain without disc herniation is a common cause of suffering and disability in the adult population. Once conservative management has failed and facet joint pain has been excluded, cervical epidural injections may be considered as a management tool. Despite a paucity of evidence, cervical epidural injections are one of the most commonly performed nonsurgical interventions in the management of chronic axial or disc-related neck pain. One hundred and twenty patients without disc herniation or radiculitis and negative for facet joint pain as determined by means of controlled diagnostic medial branch blocks were randomly assigned to one of the 2 treatment groups. Group I patients received cervical interlaminar epidural injections of local anesthetic (lidocaine 0.5%, 5 mL), whereas Group II patients received 0.5% lidocaine, 4 mL, mixed with 1 mL or 6 mg of nonparticulate betamethasone. The primary outcome measure was ≥ 50% improvement in pain and function. Outcome assessments included numeric rating scale (NRS), Neck Disability Index (NDI), opioid intake, employment, and changes in weight. Significant pain relief and functional improvement (≥ 50%) was present at the end of 2 years in 73% of patients receiving local anesthetic only and 70% receiving local anesthetic with steroids. In the successful group of patients, however, defined as consistent relief with 2 initial injections of at least 3 weeks, significant improvement was illustrated in 78% in the local anesthetic group and 75% in the local anesthetic with steroid group at the end of 2 years. The results reported at the one-year follow-up were sustained at the 2-year follow-up. Cervical interlaminar epidural

    To study the correlation between lumber disc degeneration and sacroiliac joint disorder, in order to provides a new understanding concepts and therapeutic approach for the prevention and treatment of chronic intractable low back pain. From August 2009 to October 2010,129 cases with lumbar disc herniation were studied with epidemiological methods. Among them, 61 patients with L4, disc herniation included 37 males and 24 females, ranging in aged from 20 to 75 years old, duration of the disease ranged from 1 to 144 months; The other 68 patients with L5S1 disc herniation included 32 males and 36 females,ranging in aged froml8 to 76 years old,duration of the disease ranged from 0.5 to 240 months. The clinical data, symptoms and signs,X-ray characteristics of lumbar spine and pelvis of the patients were investigated by epidemiological. The risk of lumbar disc herniation was calculated with case-control study; independent variables were screened with single factor analysis; the risk factors for lumbar disc herniation were determined with logistic regression analysis, and biomechanics analyses were taken. Among 129 patients with lumbar disc herniation, 88 cases associated with sacroiliac joint disorders, sacroiliac joint disorder was a risk factor of lumbar disc herniation (OR = 4.61, P = 0.00); 47 cases associated with sacroiliac joint disorders in 61 patients with L4,5 disc herniation, iliac crest uneven caused by iliac rotational displacement was a high risk factor of L4,5 disc herniation (OR = 11.27, P = 0.00); 41 cases associated with sacroiliac joint disorders in 68 patients with L5S1 disc herniation, lumbar sacral angle abnormalities caused by sacral tilt shift was a high risk factor L5S1 disc herniation (OR = 2.31, P = 0.03). Lumbar disc herniation and sacroiliac joint disorder are two of fallot, the two factors affect each other and there is a causal relationship. They are common exists in low back pain.

    Cervical radicular syndrome (CRS) due to a herniated disc can be safely treated by surgical decompression of the spinal root. In the vast majority of cases this relieves pain in the arm and restores function. However, conservative treatment also has a high chance on relieving symptoms. The objective of the present study is to evaluate the (cost-) effectiveness of surgery versus prolonged conservative care during one year of follow-up, and to evaluate the timing of surgery. Predisposing factors in favour of one of the two treatments will be evaluated. Patients with disabling radicular arm pain, suffering for at least 2 months, and an MRI-proven herniated cervical disc will be randomised to receive either surgery or prolonged conservative care with surgery if needed. The surgical intervention will be an anterior discectomy or a posterior foraminotomy that is carried out according to usual care. Surgery will take place within 2-4 weeks after randomisation. Conservative care starts immediately after randomisation. The primary outcome measure is the VAS for pain or tingling sensations in the arm one year after randomisation. In addition, timing of surgery will be studied by correlating the primary outcome to the duration of symptoms. Secondary outcome measures encompass quality of life, costs and perceived recovery. Predefined prognostic factors will be evaluated. The total follow-up period will cover two years. A sample size of 400 patients is needed. Statistical analysis will be performed using a linear mixed model which will be based on the 'intention to treat' principle. In addition, a new CRS questionnaire for patients will be developed, the Leiden Cervical Radicular Syndrome Functioning (LCRSF) scale. The outcome will contribute to better decision making for the treatment of cervical radicular syndrome. NTR3504.

    Chronic persistent neck pain with or without upper extremity pain is common in the general adult population with prevalence of 48% for women and 38% for men, with persistent complaints in 22% of women and 16% of men. Multiple modalities of treatments are exploding in managing chronic neck pain along with increasing prevalence. However, there is a paucity of evidence for all modalities of treatments in managing chronic neck pain. Cervical epidural injections for managing chronic neck pain are one of the commonly performed interventions in the United States. However, the literature supporting cervical epidural steroids in managing chronic pain problems has been scant. A systematic review of cervical interlaminar epidural injections for cervical disc herniation, cervical axial discogenic pain, cervical central stenosis, and cervical postsurgery syndrome. To evaluate the effect of cervical interlaminar epidural injections in managing various types of chronic neck and upper extremity pain emanating as a result of cervical spine pathology. The available literature on cervical interlaminar epidural injections in managing chronic neck and upper extremity pain were reviewed. The quality assessment and clinical relevance criteria utilized were the Cochrane Musculoskeletal Review Group criteria as utilized for interventional techniques for randomized trials and the criteria developed by the Newcastle-Ottawa Scale criteria for observational studies. The level of evidence was classified as good, fair, and limited based on the quality of evidence developed by the U.S. Preventive Services Task Force (USPSTF). Data sources included relevant literature identified through searches of PubMed and EMBASE from 1966 to December 2011, and manual searches of the bibliographies of known primary and review articles. The primary outcome measure was pain relief (short-term relief = up to 6 months and long-term > 6 months). Secondary outcome measures were improvement in functional status

    Objective: To study the value of diagnosis for internal disc disruption (IDD)with CT discography(CTD). Methods: 42 discs of 32 patients showing no disc herniation on CT or MRI, but suffering from chronic low back pain, were undertaken CTD to work out the types of CTD with correlation between contrast medium dosages and the induction of pain. Results: CTD demonstrated 4 types of IDD which was individually correlated with the contrast dosages and induced pain; furthermore the dosages for positive and negative disc cases showed significant differece (P<0.01). Conclusions: CTD can show the direct sign of internal disc disruption, providing more information than conventional discography. (authors)

  9. Calcifying discopathy in infancy in the cervical spine: Evaluation of vertebral alterations over a period of time

    Urso, S; Colajacomo, M; Migliorini, A; Fassari, F M

    1987-07-01

    CDI in the cervical spine has already been observed and described by many authors, as a well-defined clinico-radiological syndrome with a benign course. The clinical picture is composed of: pain and functional limitation, sometimes with a stiff neck, more rarely slight fever, increase of the erythrocyte sedimentation rate or leukocytosis. The radiographic picture consists of the association of morphological and structural alterations of vertebral bodies adjacent to one or more disc calcifications usually centrally sited, sometimes associated with anterior or posterior herniations. On the basis of the observation of 7 patients, in the 15-year-old range, the authors propose to evaluate the changes of both the vertebral bodies and the discs involved in the disease over a period of time. The repetition of even modest alterations, that persist in time, testify to the involvement of the vertebral growth perhaps, more than the discal alterations connected with the calcification.

  10. CT recognition of lateral lumbar disk herniation

    1982-01-01

    Although computed tomography (CT) has been shown to be useful in diagnosing posterolateral and central lumbar disk herniations, its effectiveness in demonstrating lateral herniated disks has not been emphasized. The myelographic recognition of those herniations may be difficult because root sheaths or dural sacs may not be deformed. A total of 274 CT scans interpreted as showing lumbar disk herniation was reviewed. Fourteen (5%) showed a lateral disk herniation. The CT features of a lateral herniated disk included: (1) focal protrusion of the disk margin within or lateral to the intervertebral foramen: (2) displacement of epidural fat within the intervertebral foramen; (3) absence of dural sac deformity; and (4) soft-tissue mass within or lateral to the intervertebral foramen. Because it can image the disk margin and free disk fragments irrespective of dural sac or root sheath deformity, CT may be more effective than myelography for demonstrating the presence and extent of lateral disk herniation

    2006-01-01

    It is generally accepted that cervical spine bilateral facet dislocation results in complete disruption of the posterior longitudinal ligament. The goal of this study was to evaluate the integrity of numerous spine-stabilizing structures by MRI, and to determine if any associations between injury patterns exist with respect to the posterior longitudinal ligament status. Retrospective case series. A retrospective review was performed of 30 cervical spine injury subjects with bilateral facet dislocation. Assessment of 1.5T MRI images was carried out for: intervertebral disc disruption, facet fracture, and ligamentous disruption. Statistical analyses were performed to evaluate for associations between various injury patterns and posterior longitudinal ligament status. The frequency of MRI abnormalities was: anterior longitudinal ligament disruption (26.7%), disc herniation or disruption (90%), posterior longitudinal ligament disruption (40%), facet fracture (63.3%) and disruption of the posterior column ligament complex (97%). There were no significant associations between injury to the posterior longitudinal ligament and other structures. Compared to surgical reports, MRI was accurate for determining the status for 24 of 26 ligaments (three of three anterior longitudinal ligament, seven of nine posterior longitudinal ligament, and 14 of 14 posterior column ligament complex) but generated false negatives in two instances (in both MRI showed an intact posterior longitudinal ligament that was torn at surgery).

    This paper reports on cervical hyperextension injuries that are common and often show minimal radiographic abnormalities, even with severe or unstable lesions. MR images and clinical records of 14 patients scanned within 4 months of hyperextension cervical injuries were reviewed. Clinical, radiographic, and MR findings were correlated. Nine patients had acceleration hyperextension whiplash injuries, four with acute cervical disk herniations developing radiculopathy after several weeks. Five patients injured by direct frontal head trauma presented with myelopathy and had MR evidence of cord injury, and four had acute disk herniation

    The relatively new technique of Piezosurgery is based on microvibrations, generated by the piezoelectrical effect, which results in selective bone cutting with preservation of adjacent soft tissue. To study the applicability of Piezosurgery in anterior cervical discectomy with fusion (ACDF) surgery. Prospective clinical study at the neurosurgical department of the University of Freiburg, Germany. Nine patients with cervical disc herniation and retrovertebral osteophytes who underwent ACDF surgery. Piezosurgery was evaluated with respect to practicability, safety, preciseness of bone cutting, and preservation of adjacent neurovascular tissue. Pre- and postoperative clinical and radiological data were assessed. Piezosurgery was supportively used in ACDF in nine patients with either radiculopathy or myelopathy from disc herniation or ventral osteophytes. After discectomy, osteophytes were removed with Piezosurgery to decompress the spinal canal and the foramina. Angled inserts were used, allowing for cutting even retrovertebral osteophytes. In all nine cases, Piezosurgery cut bone selectively with no damage to nerve roots, dura, or posterior longitudinal ligament. None of the patients experienced any new neurological deficit after the operation. The handling of the instrument was safe and the cut precise. Osteophytic spurs, even retrovertebral ones that generally only can be approached via corpectomies, could be safely removed because of the angled inserts through the disc space. Currently, a slightly prolonged operation time was observed for Piezosurgery. Furthermore, the design of the handpiece could be further improved to facilitate the intraoperative handling in ACDF. Piezosurgery proved to be a useful and safe technique for selective bone cutting and removal of osteophytes with preservation of neuronal and soft tissue in ACDF. In particular, the angled inserts were effective in cutting bone spurs behind the adjacent vertebra which cannot be reached with

    The purpose of this article is to review less common presentations of degenerative disc disease on MR imaging. The images of eight patients were retrospectively analyzed. Six of them had transligamentous (or noncontained) disc herniations, the fragments of which were located in the posterior epidural space in three of them. One patient had a transdural disc fragment and one patient had a disc cyst. The cyst was located in the ventrolateral epidural space. On T2-weighted images, the migrated disc fragment returned a higher signal than the disc of origin in 6 of 7 patients. The disc cyst returned a signal similar to that of cerebrospinal fluid. The MR appearances of disc fragments can be puzzling, particularly if they are located in the posterior epidural space.

    The purpose of this article is to review less common presentations of degenerative disc disease on MR imaging. The images of eight patients were retrospectively analyzed. Six of them had transligamentous (or noncontained) disc herniations, the fragments of which were located in the posterior epidural space in three of them. One patient had a transdural disc fragment and one patient had a disc cyst. The cyst was located in the ventrolateral epidural space. On T2-weighted images, the migrated disc fragment returned a higher signal than the disc of origin in 6 of 7 patients. The disc cyst returned a signal similar to that of cerebrospinal fluid. The MR appearances of disc fragments can be puzzling, particularly if they are located in the posterior epidural space. It is important to recognize the abnormalities in order to differentiate them from less common lesions such as hematoma, abscess and neurinoma. (orig.)

    Full Text Available Background : Lumbar disc herniation often causes sciatica. Many different techniques have been advocated with the aim of least possible damage to other structures while dealing with prolapsed disc surgically in the properly selected and indicated cases. Methods : Twenty six patients with clinical symptoms and signs of prolapsed lumbar intervertebral disc having radiological correlation by MRI study were subjected to disc excision by interlaminar fenestration method. Results : The assessment at follow-up showed excellent results in 17 patients, good in 6 patients, fair in 2 patients and poor in 1 patient. The mean preoperative and postoperative Visual Analogue Scores were 9.34 ±0.84 and 2.19 ±0.84 on scale of 0-10 respectively. These were statistically significant (p value< 0.001, paired t test. No significant complications were recorded. Conclusion : Procedures of interlaminar fenestration and open disc excision under direct vision offers sufficient adequate exposure for lumbar disc excision with a smaller incision, lesser morbidity, shorter convalescence, early return to work and comparable overall results in the centers where recent laser and endoscopy facilities are not available.

    at hospital. Methods. We followed all in- and outpatients diagnosed with HLD at a Danish University Hospital 2001 to 2005 eligible for the labor market in the Danish National Register on Public Transfer Payments (n = 2039). Clinical data were obtained from the Danish National Patient Register. The outcome...... were lumbar fusion alone HR 1.4 (CI = 1.1–1.8) and in combination with discectomy HR 1.6 (CI = 1.2–2.2) as compared with nonsurgical treatment, ethnicity other than Danish HR 1.55 (CI = 1.2–1.8), and female gender HR 1.2 (CI = 1.1–1.4). Discectomy, age, and year of inclusion were not associated...... with the outcome. Conclusion. The risk of an unfavorable vocational prognosis after hospital contact for HLD was substantial. Nonacademic work and less than 40 weeks of employment within year two before hospital contact were the strongest prognostic factors, but also lumbar fusion alone and in combination...

    Right- and left-sided herniation of the heart are rare but serious complications after intrapericardial pneumonectomy. A case of a symptomless right-sided herniation is described. After a large pleural effusion was aspirated, a caval vein obstruction syndrome occurred. This was successfully treated by reposition of the heart. Digital subtraction angiography of the herniated heart was performed and demonstrated the torsion of the caval vein. 38 refs.; 5 figs

    Full Text Available Herniation of the anterior lens capsule is a rare abnormality in which the capsule bulges forward in the pupillary area. This herniation can be mistaken for an anterior lenticonus where both the capsule and the cortex bulge forward. The exact pathology behind this finding is still unclear. We report the clinical, ultrasound biomicroscopy (UBM and histopathological findings of a case of herniation of the anterior lens capsule. UBM helped to differentiate this entity from anterior lenticonus. Light microscopy revealed capsular splitting suggestive of capsular delamination and collection of fluid (aqueous in the area of herniation giving it a characteristic appearance.

    Full Text Available Idiopathic spinal cord herniation is a rare and often missed cause of thoracic myelopathy. The clinical presentation and radiological appearance is inconsistent and commonly confused with a dorsal arachnoid cyst and often is a misdiagnosed entity. While ventral spinal cord herniation through a dural defect has been previously described, intravertebral herniation is a distinct entity and extremely rare. We present the case of a 70-year old man with idiopathic thoracic transdural intravertebral spinal cord herniation and discuss the clinico-radiological presentation, pathophysiology and operative management along with a review the literature of this unusual entity.

    INTRODUCTION The natural history of a lumbar hernia of the nucleus pulposus (HNP) is not fully known and clear indications for operative intervention cannot be established from the literature. Several studies have shown that the largest discs appear to have the greatest tendency to resolve. The aim of this study was to investigate whether massive prolapsed discs can be safely managed conservatively once clinical improvement has occurred. PATIENTS AND METHODS Thirty-seven patients were studied by clinical assessments and serial magnetic resonance imaging (MRI) over 2 years. Patients had severe sciatica at first, but began to show clinical improvement despite the large disc hernia-tions. Clinical assessment included the Lasegue test and neurological appraisal. The Oswestry Disability Index was used to measure function and changes in function. Serial MRI studies allowed measurement of volume changes of the herniated disc material over a period of time. RESULTS Initial follow-up at an average of 23.2 months revealed that 83% had a complete and sustained recovery at the initial follow-up. Only four patients required a discectomy. The average Oswestry disability index improved from 58% to 15%. Volumetric analysis of serial MRI scans found an average reduction of 64% in disc size. There was a poor correlation between clinical improvement and the extent of disc resolution. CONCLUSIONS A massive disc herniation can pursue a favourable clinical course. If early progress is shown, the long-term prognosis is very good and even massive disc herniations can be treated conservatively. PMID:19887021

    THE OBJECT OF STUDY: Analysis of surgical treatment results in patients with recurrent lumbar disc herniation by transforaminal lumbar interbody fusion (TLIF) and repeated laminotomy and discectomy for the improvement of pain and disability. Data analysis was performed on a complex diagnosis and treatment of 56 patients with recurrent lumbar disc herniation who had previously underwent 1-3 lumbar disc surgeries. An MRI investigation with paramagnetic contrast agent (gadolinium) was used for the diagnosis and differentiation of epidural fibrosis, and a dynamic lateral X-ray investigation was carried out for the identification of segmental instability. The evolution period after the previous surgery was between 1 and 3 years after the index surgery. Pain expression degree and dynamics were assessed with the pain visual analog scale (VAS) in early and late postoperative periods. Postoperative success was assessed by using a modified MacNab scale. The follow-up recording period after the last operation was of at least 1 year, ranging from 1 to 4 years. The surgical treatment was effective in most cases, recording a reduction in pain expression level from 7.2-7.7 points on the VAS scale to 1.7-2.1 in the early period and 2.2-2.6 in the late period (1 year). Repeated surgery was effective in 21 of 30 (70%) cases who underwent decompression surgery without fusion and in 20 of 26 (76.9%) cases who underwent repeated surgery with transforaminal lumbar interbody fusion (TLIF). Overall, postoperative success was assessed by using a modified MacNab scale. Repeated surgery is a viable option for patients who have clinical manifestations of recurrent disc herniation. Investigation with contrast agent by MRI allows differentiating disk herniation recurrences from epidural fibrosis. Supplementing repeated discectomies and decompression with intervertebral transforaminal fusion provide superior clinical outcomes, especially in patients with clinical and radiological signs of lumbar

    Degeneration of the intervertebral disc (IVD) is a common problem in dogs and humans. IVD degeneration can lead to herniation of the IVD with subsequent compression of neural structures and various clinical signs, including back pain. Current treatment of IVD disease is conservative or surgical.

    Full Text Available Low back pain is among the most frequent medical complaints and a major public health problem. 1.7 percent of cases are caused by herniated disc, 20 percent of which require interventional treatment. Percutaneous laser disc decompression (P.L.DD can be considered as an effective therapeutic alternative in certain cases."nMaterials and Methods: To determine the efficacy of this method in Iran in patient's with low back pain due to disc herniation, 40 patients according to medical history, physical examination and MRI findings were selected for this study. Patients who had canal stenosis, marginal, osteophyte, advanced disc dehydration, ruptured posterior ligament and other contraindication were excluded. CT scan was used only for needle navigation. After proper positioning of needle, nucleous pulposus was evapourated with Nd-YAG laser. Total energy was 1200-1600j. The procedure was done out patient and follow up has been done at 1 day, 1 week, 1,3, 6 and 12 months."nResults: There was no serious complication. 80 percent of patients in one-year follow up showed significant clinical improvement."nConclusion: Our findings suggests that percutaneous laser disc decompression can be considered as an effective alternative method of treatment for disc herniation and patient selection is the critical factor which determines success rate.
