    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

    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

    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.

    Described is a new automated lumbar disk aspiration technique in which a 2-mm suction cutting probe is used. The procedure allows rapid and safe removal of disk material percutaneously. The presentation describes the technique and the preliminary results of a cooperative study. The procedure is performed under local anesthesia and the aspiration probe is placed into the disk under fluoroscopic guidance and using a posterrolateral approach. One hundred twenty patients have met the study criteria, undergone the procedure, and had at least a 6-week follow-up. Of these, 74% have achieved good to excellent results, based on physician and patient satisfaction and three other criteria. Of 93 patients for whom 6-mont follow-up is available, 71% have achieved good to excellent results. No complications have been reported. The preliminary results indicate that percutaneous automated diskectomy is a low morbidity procedure that can be done on an outpatient basis and be used successfully to treat uncomplicated herniated lumbar disks

    Fifty-seven patients were examined with CT 5 years after primary myelography for disabling sciatica and suspected herniated lumbar disk. Forty were in an operated group, 22 with good and 18 with poor results evaluated by occupational handicap (21) 5 years after surgery. Seventeen patients had myelography indicating disk herniation, but were treated conservatively, 9 with good and 8 with poor result. Various spinal dimensions measured at CT did not correlate with outcome. Operated patients had narrower canals than others, and male canals were broader than those in females. Increased amount of scar tissue at L4 level correlated with poor result (p=0.008). Operated patients with poor result had more advanced lateral stenosis than those treated conservatively (p<0.001). Patients with good result after operation had more degeneration observed on CT of erector spinae muscle than those treated conservatively with good outcome. Only 9% of operated patients did not have muscle degeneration. A tendency for more frequent recurrent disk herniations could be ssen for conservatively treated patients. The narrowing of the spinal canal 5 years after operation did not correlate with the 5-year outcome. (orig.).

    1984-01-01

    Computed tomography (CT) of the lumbar spine was performed with selectively positioned 5-mm-thick axial cross sections to examine each disk level from the top of the neural foramen to the pedicle of the next caudad vertebra. One hundred consecutive patients with 116 surgical disk explorations were reviewed. There was agreement between the CT and surgical findings in 89 patients (104 explorations) in determination of presence or absence of a herniated nucleus pulposus (HNP). Discrepancy occurred in 12 instances (11 patients): two because of incorrect interpretations, five in previously operated patients, three in spondylolisthesis, and two in spinal stenosis. There were 97 true-positives, eight false-negatives, seven true-negatives, and four false-positives. If nine previously operated patients are excluded from the study, then CT was accurate in detection of presence or absence of an HNP in 93% of the disk explorations

    Full Text Available Aggressive open lumbar discectomy is the most commonly performed surgical procedure for patients with persistent low back and leg pain. In this retrospective study,  1,380 patients were evaluated for long-term results of aggressive discectomy for the single level lumbar disk herniation. Demographic data, surgical data, complications and reherniation rate were collected and clinical outcomes were assessed using visual analogue score (VAS, Oswestry disability index (ODI and modified Mcnab criteria. The mean follow-up period was 28.8 months. According to the modified Mcnab criteria, the long-term results were excellent in 640 cases, good in 445 cases, fair in 255 cases, and poor in 40 cases. The mean VAS scores for back and radicular pains and ODI at the end of 2 years were 1.1 ± 1.0, 1.5 ± 0.5 and 6.6 ± 3.1% respectively. The complications were foot drop (n=7, dural tear (n=14, superficial wound infection (n=17, discitis (n=37 and reherniation (n=64. The dural tear and superficial wound infections resolved after treatment but 28 discitis patients were treated by conservatively and the remaining 9 underwent surgery. Among reherniation patients, 58 underwent revision discectomy and 4 underwent transforaminal lumbar interbody fusion and stabilization. Aggressive discectomy is an effective treatment of lumbar disk herniation and maintains a lower incidence of reherniation but leads to a collapse of disc height and in long run gives rise to intervertebral instability and accelerates spondylosis.

    Diffusion-weighted imaging (DWI) can provide valuable structural information that may be useful for evaluating pathological changes of the lumbar nerve root. Diffusion-weighted magnetic resonance (MR) neurography has recently been introduced as an alternative way to visualize nerves, but to date, quantitative DWI and MR neurography have not been applied to evaluate the pathology of lumbar nerve roots. Our purpose was to visualize lumbar nerve roots and to analyze their morphology by MR neurography, and to measure the apparent diffusion coefficient (ADC) of lumbar nerve roots compressed by herniated disks using 1.5-T MR imaging. Ten consecutive patients (median age, 48.0 and range, 20-72 years) with monoradicular symptoms caused by a lumbar herniated disk and 14 healthy volunteers were studied. Regions of interests were placed on the lumbar roots at dorsal root ganglia (DRG) and distal spinal nerves on DWI to quantify mean ADC values. The spinal nerve roots were also visualized by MR neurography. In the patients, mean ADC values were significantly greater in the compressed DRG and distal spinal nerves than in intact nerves. MR neurography also showed abnormalities such as nerve swelling at and below the compression in the symptomatic nerve root. Increased ADC values were considered to be because of edema and Wallerian degeneration of compressed nerve roots. DWI is a potential tool for analysis of the pathophysiology of lumbar nerve roots compressed by herniated disks. (orig.)

    Gd-DTPA, a paramagnetic MR contrast agent, is most familiarly utilized for delineation of brain and cord abnormalities. Since contrast-enhanced CT may help distinguish epidural fibrosis from recurrent herniated lumbar disk, the efficacy of Gd-DTPA-enhanced MR imaging was evaluated. Symptomatic patients with previous back surgery are being evaluated with pre- and post-Gd-DTPA T1- and T2-weighted images. Results to date (over 40 cases) suggest that this technique will be extremely helpful

    Objective: To assess the concordance of MRI diagnosis for patients suspected of lumbar disk herniation by using Kappa statistic. Methods: One hundred patients (48 males and 52 females) with lumbosacral radiculm pain, aged from 17 to 86 (average 61). All patients underwent fast spin-echo T 1 and T 2 weighted imaging on a 3.0 T MR scanner and spine surface coil. Two radiologists (doctor A and doctor B) evaluated the lumbar disks from L3-4, L4-5, and L5-S1 in 50 out of the 100 patients independently. The presence of a bulging disk or a herniation was reported. Images were interpreted twice: once before and once after disclosure of clinical information. And disks of 52 patients out of the 100 samples were interpreted by the two radiologists independently without clinical information as well. The Kappa statistics was employed to assess the concordance of each radiologist's diagnoses as well as the observer variation of the two radiologists. Results: Diagnoses before and after disclosure to clinical information were concordant in 114 disks for doctor A and in 109 for doctor B, respectively. Diagnoses before and after disclosure to clinical information were not concordant in 36 disks for doctor A and in 41 disks for doctor B, respectively. The Kappa values were 0.60±0.06 and 0.57±0.06 for doctor A and doctor B, respectively. The concordance was moderate. After disclosure to clinical information, the numbers of reported bulging disks increased significantly, by 10 and 31 for doctor A and doctor B, respectively. Without clinical information, the diagnoses of the two radiologists were concordant in 77 disks, while not concordant in 79 disks. The interobserver agreement was poor (Kappa=0.24±0.06). The difference on diagenoses made between with and without clinical information mainly happened on the differential diagnosis of normal disks and bulging disks. The different diagnoses made between with and without clinical information were on 20 disks and on 30 disks for doctor

    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

    Legs burning for treating lumbar radicular pain are still in use nowadays in low socioeconomical environments. They are dangerous as the case we report shows clearly. A 49-year-old man came to our attention with severe flaccid paraparesis occurred 10 days before, almost immediately after he had immersed his legs in boiling water to treat his severe left lumbocrural pain. This was known to be due to a right L3/4 herniated disk diagnosed by magnetic resonance imaging. At the examination he showed severe motor paresis and absent reflexes of his lower limbs, while crural pain was mild and sensation and urinary function were unaffected. The results of his neurologic examination led us to suspect an acute motor axon degeneration related to thermal shock. Lumbar magnetic resonance imaging, performed before the planned electromyogram as an exception to the established routine, showed instead a giant 5- × 5.5-cm, herniated disk compressing the dural sac at L3. Prompt surgical decompression led to rapid improvement. We discuss here the pathophysiology of this unusual case and point out how medieval practices for treating sciatica-like pain are not only unjustified from a medical viewpoint but also potentially dangerous.

    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

    The primary objective of this study conducted on 100 patients is to demonstrate that performing CT-guided percutaneous discectomy for herniated disks results in a significant improvement in pain symptoms at several times (D1, D2, D7, 1 month, 3 months, 6 months). This objective assesses the effectiveness and feasibility of this technique under CT guidance in patients presenting documented lower back pain related to disk herniation that has not improved with appropriate medical treatment. The impact of various factors on the effectiveness of discectomy will also be evaluated. At 1 week, we notes a decrease in average VAS respectively of 71% and 67% in patients treated for posterolateral and foraminal herniated disks; the result for posteromedian herniated disks is only 45% in average decrease. At 6 months post op, 79% of lateralized herniated disks have a satisfactory result (≥70% decrease in pain as compared to initial pain), whereas post median herniated disks had a satisfactory result in only 50% of cases. Percutaneous fine needle discectomy probe under combined CT and fluoroscopic guidance is a minimally invasive spine surgery which should be considered as an alternative to surgery. This technique presents several advantages: the small diameter of the probe used (maximum 16G or 1.5 mm) allows a cutaneous incision of only a few millimeters, and a trans-canal approach can be possible; it also decreases the risk of ligamentary lesion and does not cause an osseous lesion of the posterior arc or of the adjacent muscular structures.

    Objective: To compare the clinical effectiveness of ozone (O 3 ) nucleus pulposus ablation only with that of O 3 nucleus pulposus ablation combined with intervertebral facet joint injection of compound Betamethasome in treating lumbar disk herniation accompanied with intervertebral facet arthritis. Methods: Eighty patients with lumbar disk herniation and intervertebral facet arthritis were equally and randomly divided into two groups. Under CT guidance, O 3 nucleus pulposus ablation was performed in patients of group A(n=40), while O 3 nucleus pulposus ablation combined with intervertebral facet joint injection of compound Betamethasome (0.5-1 ml) was carried out in patients of group B(n=40). Using double blind method the therapeutic effectiveness was evaluated before and 1 week,3,6-months after the procedure by an Oswestry Low Back Pain Disability Questionnaire. Results: One week after the procedure the effective rate of group A and group B was 65% and 82.5% respectively. Three and six months after the treatment, the effective rate was 75% and 70% respectively for group A, while it was 90% and 92.5% respectively for group B. The difference between two groups was significant (P 3 combined with intervertebral facet joint injection of compound Betamethasome is an effective and safe treatment for lumbar disk herniation accompanied with intervertebral facet arthritis.It is worth popularizing this technique in clinical practice.

    Lumbar disk herniation (LDH) with discogenic low back pain and sciatica is a common and complicated musculoskeletal disorder. The underlying mechanisms are poorly understood, and there are no effective therapies for LDH-induced pain. In the present study, we found that the patients who suffered from LDH-induced pain had elevated plasma methylglyoxal (MG) levels. In rats, implantation of autologous nucleus pulposus (NP) to the left lumbar 5 spinal nerve root, which mimicked LDH, induced mechanical allodynia, increased MG level in plasma and dorsal root ganglion (DRG), and enhanced the excitability of small DRG neurons (DRG neurons ex vivo increased the number of action potentials evoked by depolarizing current pulses. Furthermore, inhibition of MG accumulation by aminoguanidine attenuated the enhanced excitability of small DRG neurons and the mechanical allodynia induced by NP implantation. In addition, NP implantation increased levels of advanced glycation end products (AGEs) in DRG, and intrathecal injection of MG-derived AGEs induced the mechanical allodynia and DRG neuronal hyperactivity. Intrathecal injection of MG also significantly increased the expression of AGEs in DRG. Importantly, scavenging of MG by aminoguanidine also attenuated the increase in AGEs induced by NP implantation. These results suggested that LDH-induced MG accumulation contributed to persistent pain by increasing AGE levels. Thus generation of AGEs from MG may represent a target for treatment of LDH-induced pain. NEW & NOTEWORTHY Our study demonstrates that methylglyoxal accumulation via increasing advanced glycation end-product levels in dorsal root ganglion contributes to the persistent pain induced by lumbar disk herniation, which proposed potential targets for the treatment of lumbar disk herniation-induced persistent pain.

We compared long-term effects of ESI in HD and LSS patients.Methods: In a prospective, single-blind uncontrolled study, 60 patients with radicular pain due to HD (n = 32 or LSS (n = 28 were enrolled over a 9-month period. Methylprednisolone acetate 80 mg plus 0.5% bupivacaine 10 mg were diluted in normal saline up to a total volume of 10 mL, and injected into the epidural space. The amount of pain based on numeric pain score, level of activity, and subjective improvement were reported by patients after 2 and 6 months by telephone. Demographic data were analyzed with the chi-square test. The differences in numeric pain scale scores between the two groups at different times were analyzed with the t-test.Results: There were no differences between HD and LSS patients regarding age, sex, and average duration of pain prior to ESI. The degree of pain was significantly higher in LSS patients in comparison with HD patients in the pre-injection period. The amount of pain was significantly reduced in both groups 2 months after injection. This pain reduction period lasted for 6 months in the HD group, but to a lesser extent in LSS patients (P < 0.05.Discussion: Epidural methylprednisolone injection has less analgesic effect in LSS, with less permanent effect in comparison with HD.Keywords: methylprednisolone acetate, lumbar spinal stenosis, herniated disk

    To investigate the accuracy of 3 commonly used neurodynamic tests (slump test, straight-leg raise [SLR] test, femoral neurodynamic test) and 2 clinical assessments to determine radiculopathy (radiculopathy I, 1 neurologic sign; radiculopathy II, 2 neurologic signs corresponding to 1 specific nerve root) in detecting magnetic resonance imaging (MRI) findings (extrusion, subarticular nerve root compression, and foraminal nerve root compression). Validity study. Secondary care. We included subjects (N=99; mean age, 58y; 54% women) referred for epidural steroid injection because of lumbar radicular symptoms who had positive clinical and MRI findings. Positive clinical findings included the slump test (n=67), SLR test (n=50), femoral neurodynamic test (n=7), radiculopathy I (n=70), and radiculopathy II (n=33). Positive MRI findings included extrusion (n=27), subarticular nerve compression (n=14), and foraminal nerve compression (n=25). Not applicable. Accuracy of clinical tests in detecting MRI findings was evaluated using sensitivity, specificity, and receiver operating characteristics analysis with area under the curve (AUC). The slump test had the highest sensitivity in detecting extrusion (.78) and subarticular nerve compression (1.00), but the respective specificity was low (.36 and .38). Radiculopathy I was most sensitive in detecting foraminal nerve compression (.80) but with low specificity (.34). Only 1 assessment had a concurrent high sensitivity and specificity (ie, radiculopathy II) in detecting subarticular nerve compression (.71 and .73, respectively). The AUC for all tests in detecting extrusion, subarticular nerve compression, and foraminal nerve compression showed ranges of .48 to .60, .63 to .82, and .33 to .57, respectively. In general, the investigated neurodynamic tests or assessments for radiculopathy lacked diagnostic accuracy. The slump test was the most sensitive test, while radiculopathy II was the most specific test. Most interestingly, no

    Abstract: Background: Lumbar discectomy is a surgery to remove all or part of a disc cushion that helps protect the spinal column. 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 ...

    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.

    Full Text Available Cerebral edema resulting in elevated intracranial pressure is a well-known complication of galactosemia. Lumbar puncture was performed for the diagnosis of clinically suspected bacterial meningitis. Herniation of cerebral tissue through the foramen magnum is not a common problem in neonatal intensive care units because of the open fontanelle in infants. We present the case of a 3-week-old infant with galactosemia who presented with signs of cerebellar herniation after lumbar puncture.

    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.)

    It is well established that smoking has a myriad of negative effects on varies aspects of bodily health. The aim of this study was to examine the effects of the smoking status at time of surgery on the postoperative subjective pain course and health related quality of life (HRQoL) until 1 year after surgery for lumbar disc herniation (LDH). This prospective cohort study included patients ≥18 and ≤90 years of age with a symptomatic and radiological verified LDH. The current smoking patient collective (smoking 1 or more cigarettes a day) was compared with the nonsmoking collective (previous smokers without cigarette consumption for >2 months and never smokers) in respect of subjective pain sensation (measured with the visual analogue scale (VAS)) and HRQoL using the short-form (SF-12) questionnaire preoperatively, before discharge, as well as after 4 weeks and 1 year postoperatively. The primary outcome measures were the 1-year SF-12 scores (MCS and PCS) categorized into responders and non-responders. A total of 102 patients were enrolled in the study. Thirty-eight patients were current smokers (37.2%), whereas 43 (42.2%) and 21 (20.6%) patients were never-smokers and previous smokers, respectively. Four weeks and one year after surgery, both smokers and nonsmokers reported increase in the HRQoL as compared to preoperative values - the MCS increased more than the PCS. From a univariate and multivariate perspective, smoking status at time of surgery did not predict responder status. The present study results could not confirm the hypothesis that smoking at time of surgery was associated with worse outcome after surgery for LDH. Copyright © 2014 Elsevier B.V.

    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.

    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.

    The differential diagnosis between epidural fibrosis and recurrent or residual disk herniation in symptomatic patients who have been operated is often difficult. The MRI with Spin Echo T1 sequences before and after i.v. gadolinium plays and important role in the differentiation of these two entities. The signal characteristics in T1 and T2 sequences are not reliable to distinguish between herniated disk and scar. In order to evaluate the use of the FLAIR technique in the differentiation between herniated disk and epidural fibrosis we used MRI to study 37 symptomatic patients who had been operated of lumbar disk herniation, with FSE-T2 sequences in axial and sagittal planes, FLAIR in axial sections and SE-T1 in sagittal and axial sections before and after i.v. gadolinium. This sequence was used as gold standard for the final diagnosis. We conclude that the FLAIR technique is a reliable alternative in the differential diagnosis between epidural fibrosis and herniated disk, providing a positive correlation to the SE-T1-weighted images with i.v. gadolinium in 100% of the patients.

    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

    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 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

    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.

    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

    A computed tomography (CT)-confirmed L5-S1 disk protrusion is reported to be reduced following chiropractic adjustment, as seen on repeat CT scanning. Correlation of the CT reports with the patient's symptoms before and after manipulation is reported. A 38-yr-old female was treated for low back pain and right lower extremity first sacral dermatome sciatica. CT confirmed disk herniations at both the L4-L5 and L5-S1 levels were found. Motor weakness of the right gluteus maximus muscle was found and extremely tight hamstring muscles accompanying positive straight leg signs were elicited. A clinical and imaging diagnosis of an L5-S1 disk herniation was made. Distraction type chiropractic manipulation, electrical stimulation, exercises, nutrition advice and low back wellness class were administered with complete relief of sciatic pain and nearly complete relief of low back pain. Chiropractic distraction manipulation is an effective treatment of lumbar disk herniation, if the chiropractor is observant during its administration for patient tolerance to manipulation under distraction and any signs of neurological deficit demanding other types of care.

    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.

    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.

    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)

    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).

    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.

    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.

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

    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

    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.

    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.

    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).

    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

    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.

    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

    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

    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

    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

    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 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.

    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.

    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

    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

    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.

    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)

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

    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

    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.

    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)

    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.

    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.

    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.

    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.

    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.)

    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

    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.

    An MRI unit for interventional procedure is very useful for minimally invasive surgery of the brain and spine. Percutaneous laser disc decompression (PLDD) utilizing X-ray fluoroscopy is a relatively new less invasive procedure for treatment of lumbar disc herniation. MR guided laser surgery is applied to patients with disc herniation at our department. Approaching the target of the disc protrusion was easily conducted and vaporizing the disc hernia directly using a laser was possible under MR fluoroscopy. The purpose of the present study is to evaluate the usefulness of MR guided percutaneous laser disc hernia ablation (MR-guided PLDHA). As subjects, 36 patients with lumbar disc herniation, including 23 cases with L4/5 involvement and 13 cases with L5/S1 involvement were studied. Among these, 26 were males and 10 were females, age ranging from 24 to 62. We used an open type MR system (Hitachi, Airis 0.3T), a permanent, open configuration MR system. A YAG laser (LaserScope, USA) was used for PLDHA. An MR compatible 18G titanium needle 15 cm in length was used to puncture the herniated discs. The MR compatible needle was clearly visualized, and used to safely and accurately puncture the target herniated disc in each case with multidimensional guidance. Application of the laser was performed with MR guidance. The energy dose from the laser ranged from 800 to 2100 joules. In most cases, signs and symptoms improved in the patients immediately after disc vaporization. The overall success rate was 88.9%. The complication rate was 2.8%, including one case of discitis after PLDHA. MR fluoroscopy sequence permits near real time imaging and provides an easy approach to the therapeutic target of disc herniation. MR guided PLDHA is a minimally invasive procedure and is very useful for the treatment of lumbar disc protrusion. (author)

    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.

    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

    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.

    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 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.

    Full Text Available The objective was to report a case of a 63-year-old man with a history of low back pain (LBP and left leg pain for 2 years, and the symptom became more serious in the past 5 months. The patient was diagnosed with lumbar scoliosis combined with lumbar spinal stenosis (LSS and lumbar disc herniation (LDH at the level of L4-5 that was confirmed using Computerized Topography and Magnetic Resonance Imaging. The surgical team preformed a novel technique, “U” route transforaminal percutaneous endoscopic lumbar discectomy (PELD, which led to substantial, long-term success in reduction of pain intensity and disability. After removing the osteophyte mass posterior to the thecal sac at L4-5, the working channel direction was changed to the gap between posterior longitudinal ligament and thecal sac, and we also removed the herniation and osteophyte at L3-4 with “U” route PELD. The patient’s symptoms were improved immediately after the surgical intervention; low back pain intensity decreased from preoperative 9 to postoperative 2 on a visual analog scale (VAS recorded at 1 month postoperatively. The success of the intervention suggests that “U” route PELD may be a feasible alternative to treat lumbar scoliosis with LSS and LDH patients.

    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.

    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.

    Objective: To evaluate the clinical value of X-ray target puncture collagenase chemonucleolysis combined with injection of medical ozone for lumbar disc herniation. Methods: One thousand and sixty-two cases of lumbar disc herniation accepted collagenase chemonucleolysis combined with injection of medical ozone targeted by X-ray. The therapeutic effects after operation were analyzed. Results: Of all the 1062 cases, the effective rate of X-ray target puncture collagenase chemonucleolysis combined with injection of medical ozone was 95.3% at 3 months, 92.3% at 12 months, and 91.2% at 24 months after operation. Conclusion: X-ray target puncture collagenase chemonucleolysis combined with injection of medical ozone is a simple and safe method for the lumbar disc herniation. It also had fewer adverse reactions and better therapeutic effects. (authors)

    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

    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

    The objective was to determine the importance of the ''sagittal shoulder sign'' on magnetic resonance (MR) images for the diagnosis of conjoined lumbosacral nerve roots (CLNR) that are compromised by herniated disks. Magnetic resonance images of 11 patients (6 men and 5 women; age range, 25-71 years; average age, 48.7 years) with surgically proven CLNR, which was compromised by herniated disks, were retrospectively evaluated by two musculoskeletal radiologists. MR images were evaluated for the presence or absence of the sagittal shoulder sign - a vertical structure connecting two consecutive nerve roots and overlying disk on the sagittal MR images. The radiologists noted the type of accompanying disk herniation and bony spinal canal changes, as well as other characteristic MR features of CLNR, the common passage of two consecutive nerve roots through the neural foramen on axial MR images. The sagittal shoulder sign was identified with a mean frequency of 90.9% by the two observers (in 10 of 11 patients). The common passage of two consecutive nerve roots through the neural foramen on axial MR images was identified with a mean frequency of 59.1% (in 7 and 6 out of 11 patients, by observers 1 and 2, respectively). Good interobserver agreement for the sagittal shoulder sign was present (k = 0.621, p < 0.05). Observation of the sagittal shoulder sign may prove helpful for diagnosing CLNR in patients with disk herniation. In particular, this sign appears to be useful when there is no evidence of CLNR on axial MR images. (orig.)

    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.

    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.).

    2017-07-01

    A retrospective review of prospectively collected data. To determine why artificial disk replacements (ADRs) fail by examining results of 91 patients in FDA studies performed at a single investigational device exemption (IDE) site with minimum 2-year follow-up. Patients following lumbar ADR generally achieve their 24-month follow-up results at 3 months postoperatively. Every patient undergoing ADR at 1 IDE site by 2 surgeons was evaluated for clinical success. Failure was defined as <50% improvement in ODI and VAS or any additional surgery at index or adjacent spine motion segment. Three ADRs were evaluated: Maverick, 25 patients; Charité, 31 patients; and Kineflex, 35 patients. All procedures were 1-level operations performed at L4-L5 or L5-S1. Demographics and inclusion/exclusion criteria were similar and will be discussed. Overall clinical failure occurred in 26% (24 of 91 patients) at 2-year follow-up. Clinical failure occurred in: 28% (Maverick) (7 of 25 patients), 39% (Charité) (12 of 31 patients), and 14% (Kineflex) (5 of 35 patients). Causes of failure included facet pathology, 50% of failure patients (12 of 24). Implant complications occurred in 5% of total patients and 21% of failure patients (5 of 24). Only 5 patients went from a success to failure after 3 months. Only 1 patient went from a failure to success after a facet rhizotomy 1 year after ADR. Seventy-four percent of patients after ADR met strict clinical success after 2-year follow-up. The clinical success versus failure rate did not change from their 3-month follow-up in 85 of the 91 patients (93%). Overall clinical success may be improved most by patient selection and implant type.

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

    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.

    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.

    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.

    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.

From June 2011 to January 2012,the clinical data of 46 patients with lumbar intervertebral disc herniation and sciatica underwent percutaneous transforaminal endoscopic technique were retrospectively analyzed. There were 28 males and 18 females,ranging in age from 11 to 77 years old with an average of (39.7_ 15.3) years old,20 cases were L5S1 and 26 cases were L4,5. All patients had the symptoms such as lumbago and sciatica and their straight-leg raising test were positive. Straight-leg raising test of patients were instantly repeated after operation;operative time,volume of blood loss,complication, length of stay and duration of back to work or daily life were recorded. The clinical effects were assessed according to the VAS,JOA and JOABPEQ score. All operations were successful,postoperative straight-leg raising test were all negative. Operative time,volume of blood loss,length of stay,duration of back to work or daily life,follow-up time were (93.0+/-28.0) min, (20.0+/-9.0)ml, (3.1+/-1.5) d, (11.6+/-4.2) d, (13.9+/-1.6) months,respectively. VAS score of lumbar before operation and at the 1st and 3rd,6th,12th month after operation were 5.3+/-1.2,1.9+/-1.1,1.0+/-0.8,0.9+/-0.8,0.8+/-0.6,respectively;VAS score of leg before operation and at the 1st and 3rd,6th,12th month after operation were 7.2+ 1.2,0.8+/-1.2,0.5+/-0.8,0.5+/-0.8,0.3+/-0.8,respectively. Five factors of JOABPEQ score,including lumbar pain,lumbar function, locomotor activity,social life viability and mental status,were respectively 27.0+/-30.6,37.3+/-27.4,38.5+/-26.6,33.0+/-13.7,55.4+/-19.0 before operation and 83.6+/-24.8,89.4+/-15.7,87.0+/-17.9,58.4+/-14.6,79.5+/-13.4 at final follow-up.

    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.

    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.

    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.

    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.)

    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.

As diagnostic proceedings to discover disc herniation myelography and computerized tomography have been proven to be very useful. Each of those methods show a high sensitivity and accuracy. Computerized tomography seems to be the first procedure because of the lac of any risk. Myelography has been reserved for the second approach, if there is any doubt in diagnosis. This paper will especially discuss advantages and disadvantages of MRI-tomography for the diagnosis of disc herniation. In MRI-tomography we have no radiation, there is no risk for the patient and we have the possibility of slices in different orientations with the sagittal orientation having priority in diagnosis of disc herniation. A more pronounced contrast in MRI relatively to the computerized tomography with nearly the same spatial resolution is an other important fact in favour for MRI. The value of MRI diagnosis of the spine depends however mainly on the use of special surface coils and on the use of high magnetic fields which provides a good signal to noise relation and which would permit us to use a thin-slice technique. The main disadvantage by now are the relative high costs.

    The CTF nomenclature had not been tested in clinical practice. The purpose of this study was to compare the reliability and diagnostic confidence in the interpretation of disk contours on lumbar 1.5T MR imaging when using the CTF and the Nordic nomenclatures. Five general radiologists from 3 hospitals blindly and independently assessed intravertebral herniations (Schmorl node) and disk contours on the lumbar MR imaging of 53 patients with low back pain, on 4 occasions. Measures were taken to minimize the risk of recall bias. The Nordic nomenclature was used for the first 2 assessments, and the CTF nomenclature, in the remaining 2. Radiologists had not previously used either of the 2 nomenclatures. κ statistics were calculated separately for reports deriving from each nomenclature and were categorized as almost perfect (0.81-1.00), substantial (0.61-0.80), moderate (0.41-0.60), fair (0.21-0.40), slight (0.00-0.20), and poor (<0.00). Categorization of intra- and interobserver agreement was the same across nomenclatures. Intraobserver reliability was substantial for intravertebral herniations and disk contour abnormalities. Interobserver reliability was moderate for intravertebral herniations and fair to moderate for disk contour. In conditions close to clinical practice, regardless of the specific nomenclature used, a standardized nomenclature supports only moderate interobserver agreement. The Nordic nomenclature increases self-confidence in an individual observer's report but is less clear regarding the classification of disks as normal versus bulged.

    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

    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.)

    Percutaneous laser disk decompression under X-ray fluoroscopy was first reported in 1987 for minimally invasive therapy of lumbar disk hernia. In patients with disk hernia, laser vaporizes a small portion of the intervertebral disk thereby reducing the volume and pressure of the affected disk. We present the efficacy and safety of this procedure, and analysis of fair or poor response cases. In our study, 226 cases of lumbar disk hernia and 7 cases of cervical disk hernia were treated under CT guided PLDD. Japan Orthopedic Association (JOA) score and Mac-Nab criteria were investigated to evaluate the response to treatment. Improvement ratio based on the JOA score was calculated as follows. Overall success rate was 91.6% in cases lumber disk hernia, and 100% in cases of cervical disk hernia. We experienced two cases with two cases with postoperative complication. Both cases were treated conservatively. The majority of acute cases and post operative cases were reported to be 'good' on Mac-Nab criteria. Cases of fair or poor response on Mac-Nab criteria were lateral type, foraminal stenosis or large disk hernia. CT-guided PLDD is a safe and accurate procedure. The overall success rate can be increased by carefully selecting patients. (author)

    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)

    Lumbar disk herniation, degenerative disk disease, and spondylolysis are the most prevalent lumbar conditions that result in missed playing time. Lumbar disk herniation has a good prognosis. After recovery from injury, professional athletes return to play 82% of the time. Surgical management of lumbar disk herniation has been shown to be a viable option in athletes in whom nonsurgical measures have failed. Degenerative disk disease is predominately genetic but may be accelerated in athletes secondary to increased physiologic loading. Nonsurgical management is the standard of care for lumbar degenerative disk disease in the elite athlete. Spondylolysis is more common in adolescent athletes with back pain than in adult athletes. Nonsurgical management of spondylolysis is typically successful. However, if surgery is required, fusion or direct pars repair can allow the patient to return to sports.

    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.

    One of the most common indications for performing magnetic resonance (MR) imaging of the lumbar spine is the symptom complex thought to originate as a result of degenerative disk disease. MR imaging, which has emerged as perhaps the modality of choice for imaging degenerative disk disease, can readily demonstrate disk pathology, degenerative endplate changes, facet and ligamentous hypertrophic changes, and the sequelae of instability. Its role in terms of predicting natural history of low back pain, identifying causality, or offering prognostic information is unclear. As available modalities for imaging the spine have progressed from radiography, myelography, and computed tomography to MR imaging, there have also been advances in spine surgery for degenerative disk disease. These advances are described in a temporal context for historical purposes with a focus on MR imaging's history and current state. (orig.)

    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.

    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.

    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.

    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.

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

    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. Chemonucleolysis, percutaneous manual discectomy, automated percutaneous lumbar discectomy, laserdiscectomy and endoscopic procedures accessing the disc

    Gere S. diZerega

    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

    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

    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.

    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.

    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 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

    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.

    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.

    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.

    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.

    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.

    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.

    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

    Over a 4 year period, 12 college players were treated for diskogenic injury. The most common position affected was down-lineman. Symptoms consisted of low back and/or radicular pain. No players could recall the onset of symptoms relative to football activity; weightlifting was associated with symptoms in three cases. Tentative clinical diagnosis was herniated disk disease. Method of diagnosis in the athletic population is presented along with results of surgical treatment. Percutaneous diskectomy appears to be successful for disk herniations occurring at the L4-5 space or higher.

    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

    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.

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.

    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)

    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

    Thirty-two patients were examined to determine the clinical usefulness of magnetic resonance imaging (MRI) of the lumbar spine. MRI using a resistive magnet at 0.1 Tesla was compared with computed tomography (CT) and myelography. A saturation recovery (SR) technique with repetition time (TR) of 500 msec was used in all cases. There were 19 cases with disk herniation, 5 with canal stenosis, 2 with spondylosis deformans and 6 with other suspected disease. MRI showed the protrusion of disk, displacement of epidural fat and degenerative change of disk more clearly than CT and myelography. Of the 12 herniated disks, 8 disks were clearly shown and one was not detected by MRI. In some cases, herniated disk could not be differentiated from disk bulging. With further technical advance, MRI is likely to become the initial procedure for evaluation of lumbar spinal disease. (author)

    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.

    Full text: Introduction Lumbar disc herniation can be treated with lumbar micro-invasive herniotomy under CT control through transforaminal posterolateral or transchannel approach. Percutaneous access by the fine needle probe in combination with X-ray and CT control is a micro - invasive surgery of the spine, which may be considered as an alternative to traditional surgery. The advantages of this method are: the small diameter of the used probe (not more than 16 G or 1,5 mm), allowing the dermal incision to be only a few millimeters as well as the realization of transchannel access, thereby reducing the risk for susceptible ligament injury and the avoidance of bone lesions on the back arc or neighboring muscular structures. Materials and Methods: The aim of this study is to demonstrate that percutaneous lumbar herniotomy under CT control and on posterolateral and foraminal disc herniation with symptoms of pain and root irritation, leads to a significant improvement of the complaints at times immediately postinterventsional and within 6 months ( D1 , D2, D7 , 1, 2 , 6 months) . This lecture presents 55 consecutive patients with symptoms of pain and root irritation, who have made significant progress after percutaneous lumbar herniotomy under CT control and who did not have satisfactory results despite an adapted medical treatment. All patients were clinically evaluated by using visual analogue scales (VAS) for pain, lumbar and root irritation, as well as by MR images postoperatively. Results: All 55 patients showed immediate postoperative improvement of clinical symptoms and signs. Postoperative MR images also show root decompression. It is not reported about complications during the procedure. After the first week it was noted a reduction in average VAS values of 71% and 67% in patients treated for posterolateral and foraminal herniated disc; in medial disc hernia it was noted an average reduction of only 45% . Six months after micro surgery treatment a positive

    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.

    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.

    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.

    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.

    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

    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.

    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.

    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.

    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.

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.

    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 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.

    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.

    Full Text Available Does the Finneson-Cooper score reflect the true value of predicting surgical success before discectomy? The aim of this study was to identify reliable predictors for surgical success two year after surgery for patients with LDH. Prospective analysis of 154 patients with LDH who underwent single-level lumbar discectomy was performed. Pre- and post-surgical success was assessed by the Oswestry Disability Index (ODI over a 2-year period. The Finneson-Cooper score also was used for evaluation of the clinical results. Using the ODI, surgical success was defined as a 30% (or more improvement on the ODI score from the baseline. The ODI was considered the gold standard in this study. Finally, the sensitivity, specificity, and positive and negative predictive power of the Finneson-Cooper score in predicting surgical success were calculated. The mean age of the patients was 49.6 (SD = 9.3 years and 47.4% were male. Significant improvement from the pre- to post-operative ODI scores was observed (P < 0.001. Post-surgical success was 76.0% (n = 117. The patients' rating on surgical success assessments by the ODI discriminated well between sub-groups of patients who differed with respect to the Finneson-Cooper score. Regarding patients' surgical success, the sensitivity, specificity, and accuracy of the Finneson-Cooper ratings correlated with success rate. The findings indicated that the Finneson-Cooper score was reflective of surgical success before discectomy.

    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

    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.

    Herniated disk and bulging annulus are the major causes of lower back pain. It is necessary to differentiate bulging annulus from herniated disk because of their different methods of treatment. Myelography is one of the useful diagnostic methods for disk diseases even though advanced diagnostic modalities such as CT and MRI are more accurate. Functional myelography is not a new technology expect for two additional views, flexion and extension, are obtained with conventional myelography. Differentiation between bulging annulus and herniated disk by conventional myelography is based on the extent and multiplicity of extradural deformity of the contrast filled dural sac and neural sleeve as well as the changes of nerve root. There is no previous report about differential points between bulging annulus and herniated disk according to functional myelography. It is the purpose of this study to find any additional differential points on functional myelography between bulging annulus and herniated disk over convectional myelography. Authors analysed functional myelographic findings of 152 cases from July 1986 to July 1987. Among them, 22 cases who had been suffered from cervical abnormality or vague lower back pain were diagnosed as normal by myelography, and 30 cases of L4-5 herniated disk and 21 cases of L4-5 bulging annulus which had been finally diagnosed by operation were studied. The results were as follows. 1. In normal group, anterior epidural space was gradually widened from the upper lumbar vertebra downward. And anterior epidural space was more sidened at the disk level in extension view than in flexion except for L5-S1 lever. 2. In bulging annulus group, the shape of anterior epidural space in flexion state was as similar as normal. Anoterior epidural space in extension state was more sidened at the buldging annulus than normal, but lesser than herniated disk. 3. In herniated disk group, widening of anterior epidural space at the herniated disk level was

    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.

    To assess the anatomic distribution of thoracolumbar and lumbar intervertebral disk extrusions (IVDEs) in English Cocker Spaniels as compared with findings in Dachshunds and to characterize clinical findings in English Cocker Spaniels with thoracolumbar or lumbar IVDEs affecting various regions of the vertebral column. Retrospective observational study. 81 English Cocker Spaniels and 81 Dachshunds with IVDEs. Signalment, clinical signs, neurologic examination findings, and affected intervertebral disk spaces (IVDSs) were recorded for both breeds. Management methods and outcomes were recorded for English Cocker Spaniels. Lesions were categorized as thoracolumbar (IVDSs T9-10 through L1-2), midlumbar (L2-3 through L4-5), or caudal lumbar (L5-6 through L7-S1). Midlumbar and caudal lumbar IVDEs were significantly more common in English Cocker Spaniels than in Dachshunds. English Cocker Spaniels with caudal lumbar IVDEs had a longer median duration of clinical signs before evaluation and more commonly had unilateral pelvic limb lameness or spinal hyperesthesia as the predominant clinical sign than did those with IVDEs at other sites. Those with caudal lumbar IVDEs less commonly had neurologic deficits and had a higher median neurologic grade (indicating lesser severity), shorter mean postoperative hospitalization time, and faster mean time to ambulation after surgery than those with other sites affected. These variables did not differ between English Cocker Spaniels with thoracolumbar and midlumbar IVDEs. Caudal and midlumbar IVDEs were more common in English Cocker Spaniels than in Dachshunds. English Cocker Spaniels with caudal lumbar IVDE had clinical signs and posttreatment responses that differed from those in dogs with midlumbar or thoracolumbar IVDE.

    Three cadaver spines were examined by magnetic resonance imaging (MRI) with 0.1 tesla resistive magnet. Anatomic sections of lumbar intervertebral disks were compared with various MR images, saturation recovery (SR), inversion recovery (IR), T1 and T2 weighted spin echo (SE) images. And the signal intensity of degenerated disks on T2 weighted images were correlated with the histological studies. The disks were well delineated by SR and their degenerative changes were detected most sensitively by T2 weighted SE image. Two parts of disk were delineated on T2 weighted SE image. The central portion of disk showed high signal intensity and the periphery a low signal intensity. The central high signal intensity area corresponded to the combination of annulus fibrosus and nucleus pulposus, which cannot be differenciated by MR. And the peripheral low signal intensity area corresponded to the collagenous fibers of annulus fibrosus. Histologically, disks with decreased signal intensity had marked increase of collagen fibers. The intranuclear cleft were evident on T2 weighted image, and the corresponding structures thought to be caused by invagination of the lamellae of the annulus into the nucleus in the histological specimens. MRI were useful modality for evaluation of intervertebral disks, but biochemical analysis may be needed for precise interpretation of MR images of disks in addition to histological studies.

The efficacy of nucleoplasty and identified variables that can predict pain relief for nucleoplasty was reported. Patients and methods: Between December 2013 and November 2015, 47 nucleoplasty procedures on 47 lumbar disks in 31 consecutive patients were performed. The outcome was evaluated using a visual analog scale (VAS score. Improvements of ≥50% in VAS scores were considered substantial pain relief. The variables associated with pain relief after nucleoplasty included: 1 age; 2 sex; 3 body mass index; 4 hyperintensity zone at the rear of the disk; 5 hypointensity of the disk; 6 Modic changes of the end plates; 7 spinal instability pain; and 8 discography results. Results: Twenty-one patients (67.7% experienced substantial pain relief. The most common side effects following nucleoplasty were soreness at the needle puncture site (64.5%, numbness in the lower leg (12.9%, and increased intensity of back pain (9.7%. All side effects were transient. Multivariate analysis revealed that the discography results were the most critical predictor for substantial pain relief of nucleoplasty (P=0.03. The sensitivity and specificity of discography were 92.8% and 62.5%, respectively. Conclusion: Discography results could improve the success rate of nucleoplasty in the treatment of disk degenerative LBP.

    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.

    Full Text Available Objectives This study aimed to determine the prevalence of diabetes mellitus in patients with spinal stenosis and lumbar vertebral disk degeneration, and the correlation of diabetes with these diseases. Study Design This is a cross-sectional study. Methods This case–control study was performed during 2012–2014 with 110 patients suffering from lumbar spinal stenosis and 110 patients with lumbar disk herniation, who were diagnosed using clinical and radiological evidences. Additionally, 110 participants who were referred to the clinic and did not show clinical signs of degenerative diseases of the lumbar spine entered the study as a control group. Demographic data and medical histories of the patients were collected using checklists. Results A total of 50 patients (15.2% were diagnosed with diabetes, which comprised 32 (29.1% in the stenosis group, 7 (6.4% in the lumbar disk herniation group, and 11 (10% in the control group. The prevalence of diabetes in women with spinal stenosis and women with lumbar disk herniation was 35.9% and 10.3%, respectively, whereas prevalence of diabetes in women was 10.9% in the control group. This difference was statistically significant in the spinal stenosis group in comparison with the controls ( P < 0.0001. Conversely, no significant difference was found in men. Conclusions There is an association between diabetes and lumbar spinal stenosis. Diabetes mellitus may be a predisposing factor for the development of lumbar spinal stenosis.

    Based on the analysis of the results of 297 contrast myelographies (MG) by means of water soluble agents made in patients with posterior hernias of lumbar intervertebral disks (PHLID), the authors define the potentialities of this technique in the diagnosis of PHLID. Additionally, two oblique X-ray films have been included into the exicting filming routine, which may detect all specific features of intervertebral disk damage at MG. The authors make additions into the wellknown myelographic symptomatology of PHLID, by outlining the abnormal anterior configuration of a contrast column at the level of a diseased disk in PHLID at the foraminal site. The findings suggest that contrast MG with nonionic water-soluble agents is a rather effective technique in the diagnosis of PHLID

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

    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.

    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.)

    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.

    We compared the analgesic effects of intravenous (IV) paracetamol with that of dexketoprofen on postoperative pain and morphine consumption during the first 24 hour after a lumbar disk surgery. This prospective, placebo-controlled, double blind study investigated the analgesic effects of IV paracetamol and dexketoprofen on postoperative pain, morphine consumption, and morphine-related side effects after a lumbar disk surgery. Sixty American Society of Anesthesiologists 1 or 2 status patients scheduled for elective lumbar disk surgery under general anesthesia were included in the study. Patients were treated using patient-controlled analgesia with morphine for 24 hours after a lumbar disk surgery and randomized to receive IV paracetamol 1 g, dexketoprofen 50 mg, or isotonic saline (placebo). The primary endpoint was pain intensity measured by the visual analogue scale, and secondary endpoints were morphine consumption and related side effects. Pain intensity was lower in the dexketoprofen group (P=0.01) but not in the paracetamol group (P=0.21) when compared with the control group. Cumulative morphine consumption and morphine-related side effects did not reveal significant differences between the groups. The study showed that pain intensity during 24 hours after the lumbar disk surgery was significantly lowered by dexketoprofen, but not with paracetamol, as a supplemental analgesic to morphine patient-controlled analgesia when compared with controls.

    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.

    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.

    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.

    Lumbar disk degeneration (LDD) has been related to heavy physical loading. However, the quantification of the exposure has been controversial, and the dose-response relationship with the LDD has not been established. The purpose of this study was to investigate the dose-response relationship between lifetime cumulative lifting load and LDD. This was a cross-sectional study. Every participant received assessments with a questionnaire, magnetic resonance imaging (MRI) of the lumbar spine, and estimation of lumbar disk compression load. The MRI assessments included assessment of disk dehydration, annulus tear, disk height narrowing, bulging, protrusion, extrusion, sequestration, degenerative and spondylolytic spondylolisthesis, foramina narrowing, and nerve root compression on each lumbar disk level. The compression load was predicted using a biomechanical software system. A total of 553 participants were recruited in this study and categorized into tertiles by cumulative lifting load (ie, lifting load. The best dose-response relationships were found at the L5-S1 disk level, in which high cumulative lifting load was associated with elevated odds ratios of 2.5 (95% confidence interval [95% CI]=1.5, 4.1) for dehydration and 4.1 (95% CI=1.9, 10.1) for disk height narrowing compared with low lifting load. Participants exposed to intermediate lifting load had an increased odds ratio of 2.1 (95% CI=1.3, 3.3) for bulging compared with low lifting load. The tests for trend were significant. There is no "gold standard" assessment tool for measuring the lumbar compression load. The results suggest a dose-response relationship between cumulative lifting load and LDD. © 2014 American Physical Therapy Association.

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

    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

    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

    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).

    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.

    The radiological investigation of persistent or recurrent sciatica after lumbar diskectomy essentially consists of demonstrating recurrent disk herniation. Comparison between plain and contrast enhanced CT or MR examinations at the level of the diskectomy is the main step of the radiological survey. The meanings of the various radiological findings are discussed. Other lesions that may induce persistent sciatica after lumbar diskectomy include degenerative narrowing of the lateral recess, spinal instability, stress fracture of the remaining neural arch, pseudo-meningomyelocele after laminectomy.

    Concomitant spine and hip disease in patients undergoing total hip arthroplasty (THA) presents a management challenge. Degenerative lumbar spine conditions are known to decrease lumbar lordosis and limit lumbar flexion and extension, leading to altered pelvic mechanics and increased demand for hip motion. In this study, the effect of lumbar spine disease on complications after primary THA was assessed. The Medicare database was searched from 2005 to 2012 using International Classification of Diseases, Ninth Revision, procedure codes for primary THA and diagnosis codes for preoperative diagnoses of lumbosacral spondylosis, lumbar disk herniation, acquired spondylolisthesis, and degenerative disk disease. The control group consisted of all patients without a lumbar spine diagnosis who underwent THA. The risk ratios for prosthetic hip dislocation, revision THA, periprosthetic fracture, and infection were significantly higher for all 4 lumbar diseases at all time points relative to controls. The average complication risk ratios at 90 days were 1.59 for lumbosacral spondylosis, 1.62 for disk herniation, 1.65 for spondylolisthesis, and 1.53 for degenerative disk disease. The average complication risk ratios at 2 years were 1.66 for lumbosacral spondylosis, 1.73 for disk herniation, 1.65 for spondylolisthesis, and 1.59 for degenerative disk disease. Prosthetic hip dislocation was the most common complication at 2 years in all 4 spinal disease cohorts, with risk ratios ranging from 1.76 to 2.00. This study shows a significant increase in the risk of complications following THA in patients with lumbar spine disease. [Orthopedics. 2017; 40(3):e520-e525.]. Copyright 2017, SLACK Incorporated.

    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.

    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.)

    T2 mapping was used to quantify moisture content of the lumbar spinal disk nucleus pulposus (NP) and annulus fibrosus before and after exercise stress, and after rest, to evaluate the intervertebral disk function. To clarify water retention in intervertebral disks of the lumbar vertebrae by performing magnetic resonance imaging before and after exercise stress and quantitatively measuring changes in moisture content of intervertebral disks with T2 mapping. To date, a few case studies describe functional evaluation of articular cartilage with T2 mapping; however, T2 mapping to the functional evaluation of intervertebral disks has rarely been applied. Using T2 mapping might help detect changes in the moisture content of intervertebral disks, including articular cartilage, before and after exercise stress, thus enabling the evaluation of changes in water retention shock absorber function. Subjects, comprising 40 healthy individuals (males: 26, females: 14), underwent magnetic resonance imaging T2 mapping before and after exercise stress and after rest. Image J image analysis software was then used to set regions of interest in the obtained images of the anterior annulus fibrosus, posterior annulus fibrosus, and NP. T2 values were measured and compared according to upper vertebrae position and degeneration grade. T2 values significantly decreased in the NP after exercise stress and significantly increased after rest. According to upper vertebrae position, in all of the upper vertebrae positions, T2 values for the NP significantly decreased after exercise stress and significantly increased after rest. According to the degeneration grade, in the NP of grade 1 and 2 cases, T2 values significantly decreased after exercise stress and significantly increased after rest. T2 mapping could be used to not only diagnose the degree of degeneration but also evaluate intervertebral disk function. 3.

    Sixteen patients including 13 cases with disk herniation and 3 cases with spondylosis of lumbar spine were examined on a resistive MRI system operating at 0.1 T. All lesions were studied with both multiple spin echo (MSE) and low flip angle gradient echo (LF) techniques to evaluate which technique is more effective in detecting the disk degeneration and the indentation on subarachnoid space. MSE images were obtained with repetition time (TR) of 1100-1500 ms or cardiac gating, an echo time (TE) of 30, 60, 90, 120, 150, and 180 ms symmetrical 6 echoes, and total acquisition time of more than 281 sec. LF images were obtained with TR of 500, 250, and 100 ms, TE of 18 ms, a flip angle of 30 degree, and total acquisition time of 128 sec. Eleven lesions of spinal disk degeneration and 12 of indentation on subarachnoid space were detected with LF. On the other hand, 26 lesions of spinal disk degeneration and 38 of indentation on subarachnoid space were detected with MSE. Although the parameters of LF employed in this study were relatively effective to emphasize T2 * -based contrast, the ability of LF in detection of spinal disk degeneration and indentation on subarachnoid space is less than that of MSE. Signal contrast to noise ratios for normal disk and degenerative disk, epidural-fat and disk herniated material, CSF and disk herniated material, and epidural-fat and CSF were less than 4 with LF, but more than 4 with MSE. This difference of contrast to noise ratio between MSE and LF was one of the main causes of the difference of the detection rate of spinal disk degeneration and indentation on subarachnoid space.

    Contrast-enhanced MR imaging of the spine after surgery for lumbar disk herniation almost always shows pathologic changes. To investigate to what extent these changes are correlated to patients' actual clinical symptoms, we compared the postoperative MR findings in 19 asymptomatic patients with 42 symptomatic patients (43 levels). The asymptomatic patients underwent MR examination one year after surgery. Twenty-six of the symptomatic patients underwent MR one year of less after surgery, and in 16 patients (17 levels) MR was performed more than one year after surgery. Sixteen percent of the asymptomatic and 42% of the symptomatic patients had disk herniation at the level of previous surgery. Most of the herniated disks were found in the symptomatic patients less than one year after surgery. The amount of epidural scar tissue, displacement and thickening of nerve roots, and compression of the dural sac were also studied. Disk herniation as a probable cause of recurrent sciatica was a common finding among symptomatic patients examined one year or less after surgery. In comparing asymptomatic patients and symptomatic patients with more than one year between surgery and MR examination, no significant radiologic differences, including disk herniation, were found.

    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.

    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.

    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

    ículo se describen las características de esta entidad clínica, incluyendo el aspecto clínico, radiológico e histológico, para discutir la posible patogénesis y tratamiento.Herniated lumbar disc is an important as well as the most common cause of low back pain and sciatica. Many cases can be readily diagnosed by simple semiological examination. Magnetic resonance imaging (MRI provides a definitive diagnosis even in an outpatient basis. Several types of intraspinal cysts with different pathogenesis have been reported in the past, such as perineural cysts, synovial cysts, arachnoid cysts, and ganglion cysts, diseases that are difficult to differentiate from lumbar disc herniation. Recently, the authors have observed one case of intraspinal cyst communicating with the corresponding intervertebral disk, presenting clinical symptoms, signs, and even some radiographic findings undistinguishable from those of herniated disks. The diagnosis established by MRI and confirmed at surgery. This paper describes the features of this distinct clinical condition, including clinical findings, images, and histological aspects, to discuss possible pathogenesis and management.

    Due to the mathematical complexity of current musculoskeletal spine models, there is a need for computationally efficient models of the intervertebral disk (IVD). The aim of this study is to develop a mathematical model that will adequately describe the motion of the IVD under axial cyclic loading as well as maintain computational efficiency for use in future musculoskeletal spine models. Several studies have successfully modeled the creep characteristics of the IVD using the three-parameter viscoelastic standard linear solid (SLS) model. However, when the SLS model is subjected to cyclic loading, it underestimates the load relaxation, the cyclic modulus, and the hysteresis of the human lumbar IVD. A viscoelastic standard nonlinear solid (SNS) model was used to predict the response of the human lumbar IVD subjected to low-frequency vibration. Nonlinear behavior of the SNS model was simulated by a strain-dependent elastic modulus on the SLS model. Parameters of the SNS model were estimated from experimental load deformation and stress-relaxation curves obtained from the literature. The SNS model was able to predict the cyclic modulus of the IVD at frequencies of 0.01 Hz, 0.1 Hz, and 1 Hz. Furthermore, the SNS model was able to quantitatively predict the load relaxation at a frequency of 0.01 Hz. However, model performance was unsatisfactory when predicting load relaxation and hysteresis at higher frequencies (0.1 Hz and 1 Hz). The SLS model of the lumbar IVD may require strain-dependent elastic and viscous behavior to represent the dynamic response to compressive strain.

  4. [Impact of obesity in the pathophysiology of degenerative disk disease and in the morbidity and outcome of lumbar spine surgery].

    Science.gov (United States)

    Delgado-López, Pedro David; Castilla-Díez, José Manuel

    Obesity (BMI>30Kg/m 2 ) is a pandemic with severe medical and financial implications. There is growing evidence that relates certain metabolic processes within the adipose tissue, preferentially abdominal fat, with a low-intensity chronic inflammatory state mediated by adipokines and other substances that favor disk disease and chronic low back pain. Obesity greatly conditions both the preoperative evaluation and the spinal surgical technique itself. Some meta-analyses have confirmed an increase of complications following lumbar spine surgery (mainly infections and venous thrombosis) in obese subjects. However, functional outcomes after lumbar spine surgery are favorable although inferior to the non-obese population, acknowledging that obese patients present with worse baseline function levels and the prognosis of conservatively treated obese cohorts is much worse. The impact of preoperative weight loss in spine surgery has not been prospectively studied in these patients. Copyright © 2017 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

  5. Do positive MRI findings in the lumbar spine predict future seeking care for low back pain in young teenagers?

    DEFF Research Database (Denmark)

    Kjær, Per; Leboeuf-Yde, Charlotte; Korsholm, Lars

    Background: In MRI studies lumbar disk degeneration and endplate changes have been found in children and adolescents. Such MRI findings appear to be more strongly associated with LBP than in adults. However, this knowledge is mainly based on cross-sectional studies from which no inferences regarded......, nucleus form, annular tears, high intensity zones, bulging, herniation, nerve root compression, endplate changes, Modic changes, and spondylolisthesis). Associations were sought through logistic regression at each lumbar level for boys and girls separately. Statistically significant results were presented......, and annular tears and bulging at L4. Moderate predictors included reduced signal L1 and L4, disk herniation and nerve root compression L4. Other levels and findings showed no statistically significant associations.

    Problems after intervertebral disk operations are to be expected in about 25-40% of the patients operated. Progressive degnerative alterations at the disks, the vertebrae and the intervertebral joints entail chronic mechanical pain resulting from the sensitive innervation of the structures mentioned, or lead in severe cases to the alteration of the epidural space respectively the spinal nerves with corresponding peripheral neurological symptoms. As post-surgical complications spondylodiscitis, spondylitis, haematomae, liquor fistulae, and split-off bone fragments can be the cause of complaints, for which computerized tomography is a better diagnostical method than myelography.

    The radiological investigation of persistent or recurrent sciatica after lumbar diskectomy essentially consists of demonstrating recurrent disk herniation. Comparison between plain and contrast enhanced CT or MR examinations at the level of the diskectomy is the main step of the radiological survey. The meanings of the various radiological findings are discussed. Other lesions that may induce persistent sciatica after lumbar diskectomy include degenerative narrowing of the lateral recess, spinal instability, stress fracture of the remaining neural arch, pseudo-meningomyelocele after laminectomy.

    Full Text Available Objective : Compare the interlaminar blocking technique with the transforaminal blocking, with regard to pain and the presence or absence of complications. Methods : Prospective, descriptive and comparative, double-blind, randomized study, with 40 patients of both sex suffering from sciatic pain due to central-lateral or foraminal disc herniation, who did not respond to 20 physiotherapy sessions and had no instability diagnosed on examination of dynamic radiography. The type of blocking, transforaminal or interlaminar, to be performed was determined by draw. Results : We evaluated 40 patients, 17 males, mean age 49 years, average VAS pre-blocking of 8.85, average values in transforaminal technique in 24 hours, 7, 21, and 90 days of 0.71, 1.04, 2.33 and 3.84, respectively; the average VAS post-blocking for interlaminar technique was 0.89, 1.52, 3.63 and 4.88. The techniques differ only in the post-blocking period of 21 days and overall post-blocking, with significance of p=0.022 and p=0.027, respectively. Conclusion : Both techniques are effective in relieving pain and present low complication rate, and the transforaminal technique proved to be the most effective.

    Epidurograms of the lumbar spine of 446 patients with discogenic lumbosacral radiculitis were analyzed. In 147 of these patients discal hernians were removed at operation. Epidurography was shown to give an opportunity of specifying the site of discal hernians with relation to cross-section of the vertebral canal. Median hernians were characterized by light shadows of the contrast column in a straight view and by deformity in both of its lateral views. Lateral hernians were characterized by changes in a straight view where there was a niche on the contrast column from the affected side. Deformity of the contrast column in the front epidural space was characteristic for paramedian hernians in the lateral view from the affected side. The determination of the site of discal hernia with relation to the vertebral canal facilitates a choice of surgical tactics

    Full Text Available Objective is to analyze the surgical strategy, safety, and clinical results of percutaneous full-endoscopic discectomy through interlaminar or extraforaminal puncture technique for LDH. 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.

    The objective of the present study was the comprehensive analysis of the postmortem changes in the lumbar intervertebral disks within different periods after death. A total of seven vertebromotor segments were distinguished in the lumbosacral region of the vertebral column based on the examination of 7 corpses. All these segments were divided into three groups in accordance with the prescription of death coming as follows: up to 12 hours (group 1), between 12 and 24 hours (group 2), and between 24 and 36 hours (group 3) after death. The models of the segments thus obtained were subjected to the study by means of diffusion weighted MRI. The removed intervertebral disks were used for morphological and immunohistochemical investigations. The comparison of the diffusion coefficients (DI) revealed the significant difference between the intervertebral disks assigned to groups 1 and 2 (p<0.01). The number of the cells in the pulpal core, the vertebral end plate, and the fibrous ring in all the above groups of the intervertebral disks was significantly reduced (p<0.01). The analysis of the correlation dependence between cell density and diffusion coefficients has demonstrated the well apparent relationship between these characteristics of the intervertebral disks comprising groups 1 and 2. It is concluded that diffusion weighted MRI in the combination with the calculation of diffusion coefficients for the intervertebral disks provides a tool for diagnostics of prescription of death coming as confirmed by the results of the morphometric studies and immunohistochemical analysis.

    Spine surgeon survey. The objective was to investigate the failure of widespread adoption of lumbar total disk replacement (L-TDR) in the United States. L-TDR has been available for use in the United States since 2005. L-TDR has not gained wide acceptance as a treatment for degenerative disk disease despite substantial investments in product development and positive results in randomized controlled trials. Estimates of the number of L-TDR procedures performed in the United States from 2005 to 2010 were calculated using the Nationwide Inpatient Sample database. Insurance policies were assessed for L-TDR coverage through Internet search. Finally, an 18-question survey regarding surgeons' opinions toward L-TDR was distributed to the members of North American Spine Society. The estimated number of primary L-TDR procedures performed in the United States decreased from 3650 in 2005 to 1863 in 2010, whereas revision L-TDR procedures increased from 420 to 499. Of 14 major insurers, 11 (78.6%) do not cover L-TDR. In total, 613 spine surgeons responded to the survey. Over half of respondents (51.1%, 313/612) have performed L-TDR, although only 44.6% (136/305) of initial adopters currently perform the surgery. However, 81.5% (106/130) of those currently performing L-TDR have been satisfied with the results. When asked about their perceptions of L-TDR, 65.0% (367/565) indicated a lack of insurance coverage for L-TDR in their region, 54.9% (310/565) worry about long-term complications, and 52.7% (298/565) worry about the technical challenges of revision. Despite early enthusiasm for L-TDR, wide adoption has not occurred. A primary reason for this failure seems to be a lack of insurance coverage, despite intermediate-term clinical success. In addition, surgeons continue to express concerns regarding long-term outcomes and the technical difficulties of revision. This case study of a failed surgical innovation may signal increasing involvement of payers in clinical decision

    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.)

Objective: The current study was performed to explore the relationship between serum CCL3/MIP-1α levels with lumbar intervertebral disk degeneration (IDD. Patients and methods: A total of 132 disk degeneration patients confirmed by magnetic resonance imaging and 126 healthy controls were enrolled in the current study. Radiological evaluation of the IDD was conducted using a 3.0-T magnetic resonance imaging scanner for entire lumbar vertebra region. Degeneration of intervertebral disk was assessed by Schneiderman criteria. Serum CCL3/MIP-1α levels were investigated using a sandwich enzyme-linked immunosorbent assay. The Visual Analog Scale scores and Oswestry Disability Index index were recorded for clinical severity. Results: Elevated concentrations of CCL3 in serum were found in IDD patients compared with asymptomatic volunteers. The case group included 49 IDD patients with grade 1, 42 with grade 2, and 41 with grade 3. Grade 3 and 2 had significantly higher CCL3 concentrations in serum compared with those with grade 1. The serum CCL3 levels were positively related to the degree of disk degeneration. In addition, the serum CCL3 levels also demonstrated a significant correlation with the clinical severity determined by Visual Analog Scale scores and Oswestry Disability Index index. Conclusion: Serum CCL3 may serve as a biomarker of IDD. Keywords: chemokine cytokine ligand 3, intervertebral disk degeneration, cross

Coronal slices, 3-mm-thick with a 0.3-mm gap between the slices were obtained (TR/TE 600/22) through the lumbar spinal canal. All the nerve roots were visible on at least one image. One can routinely expect to demonstrate the 3rd, 4th, and 5th lumbar, and 1st sacral nerve roots on T1-weighted, 3-mm-thick coronal MR scans. We found no correlation between the degree of lumbar lordosis and the lengths of the visible nerve roots. Five patients with one of the following spinal problems: anomaly, tumor, disk herniation, and failed back surgery syndrome were examined according to our protocol. In all these cases coronal MR imaging gave the correct diagnosis. (orig.)

    Sixteen patients including 13 cases with disk herniation and 3 cases with spondylosis of lumbar spine were examined on a resistive MRI system operating at 0.1 T. All lesions were studied with both multiple spin echo (MSE) and low flip angle gradient echo (LF) techniques to evaluate which technique is more effective in detecting the disk degeneration and the indentation on subarachnoid space. MSE images were obtained with repetition time (TR) of 1100-1500 ms or cardiac gating, an echo time (TE) of 30, 60, 90, 120, 150, and 180 ms symmetrical 6 echoes, and total acquisition time of more than 281 sec. LF images were obtained with TR of 500, 250, and 100 ms, TE of 18 ms, a flip angle of 30 degree, and total acquisition time of 128 sec. Eleven lesions of spinal disk degeneration and 12 of indentation on subarachnoid space were detected with LF. On the other hand, 26 lesions of spinal disk degeneration and 38 of indentation on subarachnoid space were detected with MSE. Although the parameters of LF employed in this study were relatively effective to emphasize T2{sup *}-based contrast, the ability of LF in detection of spinal disk degeneration and indentation on subarachnoid space is less than that of MSE. Signal contrast to noise ratios for normal disk and degenerative disk, epidural-fat and disk herniated material, CSF and disk herniated material, and epidural-fat and CSF were less than 4 with LF, but more than 4 with MSE. This difference of contrast to noise ratio between MSE and LF was one of the main causes of the difference of the detection rate of spinal disk degeneration and indentation on subarachnoid space.

    This study looks into the efficacy and safety of the transforaminal lumbar epidural steroid injection (TLESI) applied to patients with radiculopathy due to lumbar disk herniation. The patients' files which were applied TLESI, were retrospectively scanned. Patients who did not respond to one-month conservative treatment and who were detected to have bulging or protruding lumbar disk herniation as a result of imaging methods were included in the study. All applications were performed with C-arm fluoroscopy under local anesthesia by outpatient method. In all cases, a mix of 80 mg triamsinolone and 0.25% bupivacaine, was transforaminally injected to the anterior epidural area. Initial VAS pain scores were compared with the values of the 1, 3 and 6th months after the application. Patient satisfaction was determined through scoring. Furthermore, early and late term complications were collected for evaluation. A total of 222 patients were administered TLESI 460 times (average: 2.1, repeat interval: 1-6 times). The applications were carried out most frequently at the levels of L4-L5 and L5-S1. While the initial VAS score average was 8.2±0.7, after TLESI, it was 5.0±1.6, 4.8±1.5 and 5.1±1.5 in the 1, 3 and 6th months, respectively. 63.9% of the patients (n=142) defined the treatment as 'good and excellent'. No major complications were experienced and the overall minor complication rate was 11.1%. It was seen that TLESI was an efficient and safe method in the short and medium term.

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.

    Reducing lumbar spine MRI scanning time while retaining diagnostic accuracy can benefit patients and reduce health care costs. This study compares the effectiveness of a rapid lumbar MRI protocol using 3D T2-weighted sampling perfection with application-optimized contrast with different flip-angle evolutions (SPACE) sequences with a standard MRI protocol for evaluation of lumbar spondylosis. Two hundred fifty consecutive unenhanced lumbar MRI examinations performed at 1.5 T were retrospectively reviewed. Full, rapid, and complete versions of each examination were interpreted for spondylotic changes at each lumbar level, including herniations and neural compromise. The full examination consisted of sagittal T1-weighted, T2-weighted turbo spin-echo (TSE), and STIR sequences; and axial T1- and T2-weighted TSE sequences (time, 18 minutes 40 seconds). The rapid examination consisted of sagittal T1- and T2-weighted SPACE sequences, with axial SPACE reformations (time, 8 minutes 46 seconds). The complete examination consisted of the full examination plus the T2-weighted SPACE sequence. Sensitivities and specificities of the full and rapid examinations were calculated using the complete study as the reference standard. The rapid and full studies had sensitivities of 76.0% and 69.3%, with specificities of 97.2% and 97.9%, respectively, for all degenerative processes. Rapid and full sensitivities were 68.7% and 66.3% for disk herniation, 85.2% and 81.5% for canal compromise, 82.9% and 69.1% for lateral recess compromise, and 76.9% and 69.7% for foraminal compromise, respectively. Isotropic SPACE T2-weighted imaging provides high-quality imaging of lumbar spondylosis, with multiplanar reformatting capability. Our SPACE-based rapid protocol had sensitivities and specificities for herniations and neural compromise comparable to those of the protocol without SPACE. This protocol fits within a 15-minute slot, potentially reducing costs and discomfort for a large subgroup of

    Full Text Available Abstract Background No prior studies have examined systematic bias in the musculoskeletal physical examination. The objective of this study was to assess the effects of bias due to prior knowledge of lumbar spine magnetic resonance imaging findings (MRI on perceived diagnostic accuracy of the physical examination for lumbar radiculopathy. Methods This was a cross-sectional comparison of the performance characteristics of the physical examination with blinding to MRI results (the 'independent group' with performance in the situation where the physical examination was not blinded to MRI results (the 'non-independent group'. The reference standard was the final diagnostic impression of nerve root impingement by the examining physician. Subjects were recruited from a hospital-based outpatient specialty spine clinic. All adults age 18 and older presenting with lower extremity radiating pain of duration ≤ 12 weeks were evaluated for participation. 154 consecutively recruited subjects with lumbar disk herniation confirmed by lumbar spine MRI were included in this study. Sensitivities and specificities with 95% confidence intervals were calculated in the independent and non-independent groups for the four components of the radiculopathy examination: 1 provocative testing, 2 motor strength testing, 3 pinprick sensory testing, and 4 deep tendon reflex testing. Results The perceived sensitivity of sensory testing was higher with prior knowledge of MRI results (20% vs. 36%; p = 0.05. Sensitivities and specificities for exam components otherwise showed no statistically significant differences between groups. Conclusions Prior knowledge of lumbar MRI results may introduce bias into the pinprick sensory testing component of the physical examination for lumbar radiculopathy. No statistically significant effect of bias was seen for other components of the physical examination. The effect of bias due to prior knowledge of lumbar MRI results should be considered

    Purpose. The spine is an important source of pain and disability, affecting two thirds of adults at some time in their lives. Treatment in these patients is mainly conservative medical management, based on medication, physical therapy, behavioral management, and psychotherapy, surgery being limited to elective cases with neurologic deficits. This study was carried out to evaluate the efficacy of percutaneous nucleoplasty in patients affected by painful diskal protrusions and contained herniations. Methods. From February 2004 to October 2005, 72 patients (48 men, 24 women; mean age 48 years) affected by lumbar disk herniation were treated with nucleoplasty coblation. All patients were evaluated clinically and with radiography and MRI in order to confirm the presence of lumbalgic and/or sciatalgic pain, in the absence of major neurologic deficit and with lack of response after 6 weeks of conservative management. Results. Average preprocedural pain level for all patients was 8.2 (on a visual analog scale of 1 to 10), while the average pain level at 12 months follow-up was 4.1. At the 1 year evaluation, 79% of patients demonstrated a statistically significant improvement in numeric pain scores (p < 0.01): 17% (12 patients) were completely satisfied with complete resolution of symptoms, and 62% (43 patients) obtained a good result. Conclusion. Our data indicate that nucleoplasty coblation is a promising treatment option for patients with symptomatic disk protrusion and herniation who present with lumbalgic and/or sciatalgic pain, have failed conservative therapies, and are not considered candidates for open surgery

    Full Text Available Minimally invasive spine surgery prevents alteration of paraspinal muscles and avoids traditional open surgery, so in the majority of cases, recovery is much quicker and patients have less back pain after surgery. The authors describe an endoscopic approach to lumbar disc herniation by the Destandau's method originated in Bordeaux. Destandau designed ENDOSPINE for discectomy will be inserted, and the procedure will continue using endoscopy. The Endoscopic approach to lumbar disc herniation by Destandau's method offers a convenient access to lumbar disc herniation with less complications and negligible morbidity. It gives maximum exposure to the disc space with maximal angles and minimal cutaneous incision. Contrary to other minimally invasive approaches, the visual field in discectomy by Destandau technique is broad and depending on the workability of ENDOSPINE an adequate access to lumbar disc herniation is possible.

    Thirty-three patients with recurrent sciatica after lumbar-disk surgery were studied for recurrent herniated nucleus pulposus (HNP) by CT alone and CT-discography (CTD). Twenty-six patients underwent surgical reexploration allowing correlation with CTD. CTD made a correct diagnosis of recurrent HNP in twenty-one patients showing an extravasation of the contrast medium from the disk space into the medullary canal. In two cases CTD was positive for recurrent HNP but surgery showed only fibrosis. The amount of contrast leak was very small in these two cases along the posterior common longitudinal ligament, and the junction with the disk was very narrow. Because of their clinical presentation three patients with negative studies were operated upon. One showed only fibrosis and the two others showed an associated disk fragment. Among the twenty-one true-positive cases, seven showed a combination of recurrent HNP and scarring. Contamination of CSF by the contrast medium through the dura was observed in two patients. Although a prospective comparative study between CTD and IV-contrast-enhanced CT is necessary, CTD appears to be a useful diagnostic procedure for recurrent HNP after surgery of the lumbar spine.

    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

    Full Text Available The aim of this study was to compared the efficacy of paracetamol–codeine phosphate and naproxen sodium–codeine phosphate on postoperative pain and tramadol consumption during the first 24 hours after a lumbar disk surgery. After Ethics Committee approval and informed consent had been obtained, 64 patients were allocated into three groups. Patients received oral paracetamol–codeine (300 mg + 30 mg; Group P, naproxen sodium–codeine (550 mg + 30 mg; Group N, or placebo tablets (Group C 30 minutes prior to induction of anesthesia. Patient-controlled analgesia was supplied postoperatively using tramadol. Pain intensity, tramadol consumption, and side effects were recorded every 1 hour, 2 hours, 6 hours, 12 hours, and 24 hours after surgery. Whole study period pain intensity (visual analogue scale scores was lower in Group P (p = 0.007 and Group N (p = 0.001, compared with Group C, however, there was no statistically significant difference between Group P and Group N regarding pain intensity (p > 0.05. Tramadol consumption was lower in Group P and Group N, compared with Group C (p < 0.001, and in turn the lowest incidence of tramadol consumption was detected in Group P compared with Group N (p < 0.001 and Group C (p < 0.001. Side effects were similar between the groups. Preemptive administration of paracetamol–codeine and naproxen sodium–codeine combination significantly reduced tramadol consumption and provided more effective analgesia compared with placebo. The paracetamol–codeine combination was superior to naproxen sodium–codeine with regard to tramadol consumption.

    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 report a case of a human-habituated mountain gorilla, Alvila, resident at the San Diego Zoo, who was found to have a herniated intervertebral lumbar disc after being attacked by the gorilla troop's silverback male gorilla. Ultimately, the gorilla required surgical intervention for her disease and made a full recovery. To our knowledge, this is the only known case of spine surgery. A 36-year-old female human-habituated mountain gorilla (Gorilla beringei beringei), resident at the San Diego Zoo, was noticed by caregivers to walk with a substantial limp after being attacked by the gorilla troop's silverback male gorilla. Magnetic resonance (MR) imaging of her lumbar spine revealed a large herniated disk at the L1-2 level on the right. This finding appeared to correlate well with the gorilla's symptoms. The gorilla underwent a lumbar diskectomy under loupe. Post-operatively the gorilla did very well. The right leg weakness was immediately improved post-operatively. The gorilla continued to "crutch walk" initially, swinging on the upper extremities and not bearing weight on the lowers. However, by 2 weeks the limp was no longer noticeable to the zoo caregivers. The wound healed well and there was no evidence of wound infection or CSF leak. The gorilla was reunited with her troop and has reintegrated well socially. With 10 months of follow-up, the gorilla continues to do well. This is the only known case of spine surgery in a gorilla. For best surgical results, one needs to consider the similarities and differences between the gorilla and human vertebral anatomy. We believe that careful pre-operative planning contributed to the good early post-operative result. Ultimate assessment of the long-term outcome will require additional follow-up.

    Technical case report. The authors report a new percutaneous endoscopic lumbar discectomy (PELD) technique for the treatment of lumbar disc herniation via a contralateral approach. When there are highly down-migrated lumbar disc herniation along just medial to pedicle and narrow ipsilateral intervertebral foramen, the conventional PELD is not easily accessible via ipsilateral transforaminal route. Five patients manifested gluteal and leg pain because of a soft disc herniation at the L4-L5 level. Transforaminal PELD via a contralateral approach was performed to remove the herniated fragment, achieving complete decompression of the nerve root. The symptom was relieved and the patient was discharged the next day. When a conventional transforaminal PELD is difficult because of some anatomical reasons, PELD via a contralateral route could be a good alternative option in selected cases.

    Full Text Available Impaired motor and sensory functions have been associated with low back pain (LBP. This includes disturbances in a wide range of sensorimotor control e.g. sensory dysfunctions, impaired postural responses and psychomotor control. However, the physiological mechanisms, clinical relevance and characteristics of these findings in different spinal pathologies require further clarification. The purposes of this study were to investigate postural control, lumbar muscle function, movement perception and associations between these findings in healthy volunteers (n=35, patients with lumbar disc herniation (n=20 and lumbar spinal stenosis (LSS, n=26. Paraspinal muscle responses for sudden upper limb loading and muscle activation during flexion-extension movement and the lumbar endurance test were measured by surface electromyography (EMG. Postural stability was measured on a force platform during two- and one-footed standing. Lumbar movement perception was assessed in a motorised trunk rotation unit in the seated position. In addition, measurements of motor-(MEP and somatosensory evoked potentials (SEP and needle EMG examination of lumbar multifidus muscles were performed in the LSS patients. Clinical and questionnaire data were also recorded. A short latency paraspinal muscle response (~50 ms for sudden upper limb loading was observed. The latency of the response was shortened by expectation (p=0.017. The response latency for unexpected loading was similar in healthy persons and disc herniation patients but the latency was not shortened by expectation in the patients (p = 0.014. Also impaired postural control (p < 0.05 and lumbar movement perception (p = 0.012 were observed in disc herniation patients. The impaired lumbar movement perception (p=0.054 and anticipatory muscle activation (p = 0.043 tended to be restored after successful surgery but postural control had still not recovered after 3 months of follow-up.

    síntomas preoperatorios de los pacientes con HDL. Los signos y síntomas evaluados fueron el dolor lumbar, el dolor en la pierna, los disturbios motores y sensitivos y el signo de Lasègue. CONCLUSIÓN: el índice de éxito de la cirugía de los pacientes con HDL refractarios al tratamiento clínico se correlaciona con la ausencia de lumbalgia, la presencia de ciatalgia con tiempo de evolución de hasta seis meses, el déficit sensitivo presente de forma aislada o asociado al déficit motor y la presencia de signo de Lasègue positivo en el periodo preoperatorio.INTRODUCTION: lumbar disc herniation (LDH is currently a prevalent pathology which leads to physical, psychological and social limitations for the patient. The most frequent signs and symptoms are lumbocyatalgia, motor and sensitive disorders and Lasègue's sign. In patients with LDH refractory to medical treatment, discectomy is the standard procedure to improve the symptoms. OBJECTIVES: to study the prognostic relevance of signs and symptoms in patients with LDH refractory to medical treatment. METHODS: a survey was performed, in the main biomedical databases, for articles that studied the percentage of improvement and prognostic value of the preoperative signs and symptoms of patients with LDH. The signs and symptoms evaluated were lumbar pain, leg pain, motor and sensitive disorders and Lasègue's sign. CONCLUSION: the success rate in surgery of patients with LDH refractory to medical treatment is correlated with the absence of lumbalgia, the presence of cyatalgia over up to six months, the sensitive deficit present alone or associated with motor deficit and the presence of positive Lasègue's sign during the preoperative period.

    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.

    The aims of this preliminary study were to demonstrate the feasibility of in vivo diffusion tensor imaging (DTI) and fibre tracking (FT) of the lumbar nerve roots, and to assess potential differences in the DTI parameters of the lumbar nerves between healthy volunteers and patients suffering from disc herniation. Nineteen patients with unilateral sciatica related to posterolateral or foraminal disc herniation and 19 healthy volunteers were enrolled in this study. DTI with tractography of the L5 or S1 nerves was performed. Mean fractional anisotropy (FA) and mean diffusivity (MD) values were calculated from tractography images. FA and MD values could be obtained from DTI-FT images in all controls and patients. The mean FA value of the compressed lumbar nerve roots was significantly lower than the FA of the contralateral nerve roots (p=0.0001) and of the nerve roots of volunteers (p=0.0001). MD was significantly higher in compressed nerve roots than in the contralateral nerve root (p=0.0002) and in the nerve roots of volunteers (p=0.04). DTI with tractography of the lumbar nerves is possible. Significant changes in diffusion parameters were found in the compressed lumbar nerves. (orig.)

    To present a radiculopathy case due to unilateral facet hypertrophy developing three years after a lumbar disc hernia operation. A fifty two-year-old female patient, who had been operated on for a left L5-S1 herniated lumbar disc three years ago, was hospitalized and re-operated with a diagnosis of unilateral facet hypertrophy. She had complaints of left leg pain and walking restrictions for the last six months. Left Straight Leg Raising test was positive at 40 degrees , left ankle dorsiflexion muscle strength was 4/5, left Extensor Hallucis Longus muscle strength was 3/5, and left Achilles reflex was hypoactive. Lumbar spinal Magnetic Resonance Imaging revealed left L5-S1 facet hypertrophy. Lumbar radiculopathy due to lumbar facet hypertrophy is a well-known neurological condition. Radicular pain develops during the late postoperative period following lumbar disc hernia operations that are often related to recurrent disc herniation or to formation of post-operative scar tissue. In addition, it can be speculated that unilateral facet hypertrophy, which may develop after a disc hernia operation, might also be one of the causes of radiculopathy.

    In order to assess changes occurring in disk hernias and disk spaces following percutaneous nucleotomy a follow-up CT was carried out an average of 6 months after treatment of 69 disks in 60 patients. Forty-three of the disks were also reexamined at an average of 11 months after the first follow-up. Twenty-seven percent of the hernias were reduced in size at the first follow-up. Fourteen percent were reduced and 7% had increased between the first and second follow-ups. The medium-sized and large hernias were more frequently reduced compared to the smaller ones. Reduction of the disk space was found in 29% of the cases at first follow-up. An additional 24% were reduced between the first and second follow-ups. No association was demonstrated between change in size of the herniation or disk space and clinical outcome or amount of nucleous material removed at nucleotomy. (orig.).

    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.

    1985-05-01

    It is not unusual for intervertebral disk calcifications to be detected in pediatric practice, the 150 or so cases reported in the literature probably representing only a small proportion of lesions actually diagnosed. Case reports of 33 children with intervertebral disk calcifications were analyzed. In the majority of these patients (31 of 33) a diagnosis of "idiopathic" calcifications had been made, the cervical localization of the lesions being related to repeated ORL infections and/or trauma. A pre-existing pathologic factor was found in two cases (one child with juvenile rheumatoid arthritis treated by corticoids and one child with Williams and Van Beuren's syndrome). An uncomplicated course was noted in 31 cases, the symptomatology (pain, spinal stiffness and febricula) improving after several days. Complications developed in two cases: one child had very disabling dysphagia due to an anteriorly protruding cervical herniated disc and surgery was necessary; the other child developed cervicobrachial neuralgia due to herniated disc protrusion into the cervical spinal canal, but symptoms regressed within several days although calcifications persisted unaltered. These findings and the course of the rare complications documented in the literature suggest the need for the most conservative treatment possible in cases of disc calcifications in children.

    1988-04-01

    In order to estimate the clinical value of lumbar CT assisted discography (CTD), results obtained by this method were compared with histological findings of the cross section of the spine in fresh human cadavera. Based on these findings, preoperative CTD of lumbar disc herniation was investigated. In the discs of human cadavera, the contrast medium mainly invaded the fissures of nucleus pulposus and the ruptures of annulus fibrosus and then diffused to the surrounding tissues. These ruptures were classified into two categories: radial and circumferential. This indentification was possible only in CTD and was obscure in the usual discogram. Not all the ruptures could be dyed in a severe degenerative disc, and a rupture which was not communicated with nucleus pulposus was not dyed in a mild degenerative disc. In the preoperative CTD of lumbar disc herniation, the posterior radial ruptures representing the route of herniated nuclei were characteristic and the circumferential ruptures were found complicated.

    % returned to work if surgically treated within three months. In contrast, only 50% of those whose sick leave exceeded three months returned to work. CONCLUSION: The present analysis suggests that the return-to-work rate after lumbar disc herniation surgery is affected by the length of sick leave. FUNDING......INTRODUCTION: Lumbar disc herniation (LDH) is associated with high morbidity and significant socio-economic impact as the majority of the patients are of working age. The purpose of this study was to determine the impact of length of sick leave on the return-to-work rate after lumbar disc...... herniation surgery. METHODS: This was a single-centre study of LDH patients who underwent surgery from 18 May 2009 through 28 November 2014. Data were collected prospectively from the DaneSpine database.

    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

    Lumbar spondylosis is a chronic, noninflammatory disease caused by degeneration of lumbar disc and/or facet joints. The etiology of lumbar spondylosis is multifactorial. Patients with lumbar spondylosis complain of a broad variety of symptoms including discomfort in the low back lesion, whereas some of them have radiating leg pain or neurologenic intermittent claudication (lumbar spinal stenosis). The majority of patients with spondylosis and stenosis of the lumbosacral spine can be treated nonsurgically. Nonsteroidal anti-inflammatory drugs and COX-2 inhibitors are helpful in controlling symptoms. Prostaglandin, epidural injection, and transforaminal injection are also helpful for leg pain and intermittent claudication. Operative therapy for spinal stenosis or spondylolisthesis is reserved for patients who are totally incapacitated by their condition.

    Full Text Available Objectives: To compare the outcomes of prone and supine lumbar traction in patients with chronic discogenic low back pain. Methods: The test was prospective and randomized control trial. The structure of trial was Urban Physical Medicine and Rehabilitation clinic. Participants was included of A total of 124 subjects with chronic low back pain (LBP and evidence of a degenerative and/or herniated inter-vertebral disk at 1 or more levels of the lumbar spine, who have not our exclusion criteria. There was A 4-week course of lumbar traction, prone or supine in case and control groups consecutively, consisting of six 30-minute sessions every other days, followed by four 30-minute sessions every 3 days. The numeric Visual pain rating scale and the Oswestry Disability Index (ODI were completed at pre-intervention and discharge (within 2 weeks of the last visit. Results: A total of 124 subjects completed the treatment protocol. We noted significant improvements for all post-intervention outcome scores when compared with pre-intervention scores (P<0.01. Also found significant difference between 2 groups in favor of prone traction (P<0.01 Discussion: Traction applied in the prone position for 4 weeks was associated with improvements in pain intensity and ODI scores at discharge, in a sample of patients with activity limiting LBP. However, because we lacked a reasonable long time follow-up, we cannot imply a long lasting relationship between the traction and outcome, and a long time follow-up is suggested.

    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.

The position of DRG is not related to the occurrence of radicular symptoms in disc herniation, while in lumbar spondylosis proximally placed DRG are related to both of unilateral and bilateral occurrence of redicular symptoms. Unilateral occurrence of radicular symptoms is influenced by surrounding tissues of the nerve root, rather than the position of DRG. (author).

    This report concerns 12 patients, eight young adults and four adolescents, presenting with lumbar or sciatic pain. This was associated with an unusual defect of the inferior and posterior edges of the vertebral bodies of L4 or L5, together with a small bony ridge protruding into the spinal canal. We found 11 similar cases in the literature, all involving adolescents except for one young adult. It has been considered to be the result of a fracture of the posterior ring apophysis in association with a herniated disc. In our cases, in the absence of any known previous trauma, the radiological features and surgical results and the similarity and frequent association with typical lesions of Scheuermann disease, all suggest a posterior marginal cartilaginous node. The inferior lumbar location and frequent association with herniated disc and sciatic nerve root compression in young patients are discussed.

    Degenerative diseases of the lumbar spine and associated lower back pain represent a major epidemiological and health-related economic challenge. A distinction is made between specific and unspecific lower back pain. In specific lower back pain lumbar disc herniation and spinal canal stenosis with or without associated segment instability are among the most frequent pathologies. Diverse conservative and operative strategies for treatment of these diseases are available. The aim of this article is to present an overview of current data and an evidence-based assessment of the possible forms of treatment. An extensive literature search was carried out via Medline plus an additional evaluation of the authors' personal experiences. Conservative and surgical treatment represent efficient treatment options for degenerative diseases of the lumbar spine. Surgical treatment of lumbar disc herniation shows slight advantages compared to conservative treatment consisting of faster recovery of neurological deficits and a faster restitution of pain control. Surgical decompression is superior to conservative measures for the treatment of spinal canal stenosis and degenerative spondylolisthesis. In this scenario conservative treatment represents an important supporting measure for surgical treatment in order to improve the mobility of patients and the outcome of surgical treatment. The treatment of specific lower back pain due to degenerative lumbar pathologies represents an interdisciplinary challenge, requiring both conservative and surgical treatment strategies in a synergistic treatment concept in order to achieve the best results for patients.

    Full Text Available Lumbar spinal stenosis results from the progressive combined narrowing of the central spinal canal, the neurorecesses, and the neuroforaminal canals. In the absence of prior surgery, tumor, or infection, the spinal canal may become narrowed by bulging or protrusion of the intervertebral disc annulus, herniation of the nucleus pulposis posteriorly, thickening of the posterior longitudinal ligament, hypertrophy of the ligamentum flavum, epidural fat deposition, spondylosis of the intervertebral disc margins, or a combination of two or more of the above factors. Patients with spinal stenosis become symptomatic when pain, motor weakness, paresthesia, or other neurologic compromise causes distress. In one case, we administrated oriental medical treatment with acupuncture treatment and herb-medicine. Oriental medical treatment showed desirable effect on lumbar spinal stenosis.

    2014-01-01

    Lumbar lordosis is a key postural component that has interested both clinicians and researchers for many years. Despite its wide use in assessing postural abnormalities, there remain many unanswered questions regarding lumbar lordosis measurements. Therefore, in this article we reviewed different factors associated with the lordosis angle based on existing literature and determined normal values of lordosis. We reviewed more than 120 articles that measure and describe the different factors associated with the lumbar lordosis angle. Because of a variety of factors influencing the evaluation of lumbar lordosis such as how to position the patient and the number of vertebrae included in the calculation, we recommend establishing a uniform method of evaluating the lordosis angle. Based on our review, it seems that the optimal position for radiologic measurement of lordosis is standing with arms supported while shoulders are flexed at a 30° angle. There is evidence that many factors, such as age, gender, body mass index, ethnicity, and sport, may affect the lordosis angle, making it difficult to determine uniform normal values. Normal lordosis should be determined based on the specific characteristics of each individual; we therefore presented normal lordosis values for different groups/populations. There is also evidence that the lumbar lordosis angle is positively and significantly associated with spondylolysis and isthmic spondylolisthesis. However, no association has been found with other spinal degenerative features. Inconclusive evidence exists for association between lordosis and low back pain. Additional studies are needed to evaluate these associations. The optimal lordotic range remains unknown and may be related to a variety of individual factors such as weight, activity, muscular strength, and flexibility of the spine and lower extremities.

    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

    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.

    Full Text Available Lung herniation (LH is a rare clinical entity involving the protrusion of lung outside the thoracic cage. It has a variety of etiologies and clinical presentations, making diagnosis difficult. We present a case of a 20-year-old male who reported pleuritic pain after falling from a skateboard. Evaluation through computed tomography (CT scanning of the chest revealed an anterior lung hernia associated with rib fractures. This case emphasizes the need for clinicians to include lung herniation in the differential diagnosis of patients with trauma and inexplicable or persistent pulmonary issues.

    We present a 7-year-old boy, with a history of neonatal intraventricular hemorrhage, leading to hydrocephalus with multiple shunt revisions. The current presentation of shunt failure and resultant hydrocephalus was complicated by herniation of the trigone of the lateral ventricle into the posterior fossa. Despite the dramatic radiological appearance, this herniation of the lateral ventricle was not accompanied by any additional clinical signs or symptoms other than those usually attributed to hydrocephalus. Following successful shunt revision, the patient returned to his baseline clinically with the trigone reverting back to its normal position. We also present a second companion case. (orig.)

    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.

    1988-01-01

    Computed tomography (CT) scans of lumbar canal stenosis (LCS, n = 20), osteoarthritis (OA, n = 65), disk herniation (n = 21), and lumbar pain (n = 23) were reviewed for the quanlitative evaluation of the vertebral canal and stenosis factors. Trefoil type on transverse sections of the bony vertebral canal was observed in 23 %, having no implications for pathologic significance at the L5 level. The degree of degeneration in soft tissues inside the vertebral canal varied according to diseases. This was most noticeable at the L4/L5 level in the LCS group. The morphological CT appearance of vertebral arch were divided into three types: I - the concave inner part, II - the linear inner part, and III - the convex inner part to the vertebral canal. In the group of LCS, the incidences of types II and III were high at the L5/S1 and at the L4/L5 levels, respectively. As for the angle of apophyseal joint, the incidence of sagittal joint was high at the L3/L4 and L4/L5 levels in the group of LCS. The incidence of degenerative changes was high in the groups of LCS and OA, suggesting some relationship between degenerative degree and both sagittal and asymmetric joints. This was noticeable at the L4/L5 level. Calcification surrounding the joint was seen in 13 %, reflecting the relationship to the degenerative changes. There was no relationship between degenerative changes and vacuum joint phenomenon observed in 18 %. As for the area less than 90 mm 2 of the dural canal, there was no morphological change between the LCS and OA groups. In the symptomatic mechanism in the case of LCS, morphological dynamic and unstable factors may be involved. (Namekawa, K.) 67 refs

    The present study describes the radiological and histological changes in the canine intervertebral disk after the experimental injection of chymopapain as the chemical reagent, and determines the appropriate dose of the enzyme for treatment of herniated disks. By radiography, narrowing of the disk space was observed within 2 weeks after the injection of chymopapain, and recovered to 74.1% in the 0.1 mg group, 61.1% in the 1.0 mg group and 71.7% in the 10.0 mg group at 12 weeks. The disk space recovery showed a tendency to delay with aging. Microscopically, proteoglycan positive matrix appeared and the nuclear space was reduced in each disk at 2 weeks after chymopapain injection. The nucleus pulposus contained an irregularly-defined mass consisting of clusters of degenerated notochordal cells surrounded by proliferated chondrocytes and collagen matrix. In each disk at 12 weeks after chymopapain injection, the center of the nucleus pulposus was replaced by fibrocartilage tissue. In the disk into which 10.0 mg chymopapain was injected, the nuclear space filled with dense fibrocartilage tissue without a regenerated matrix component and narrowing of the disk were maintained. It is suggested that canine chemonucleolysis with 10.0 mg of chymopapain reduces the interdiskal pressure. This treatment may therefore relieve the signs and symptoms of herniation of the nucleus pulposus, and may effect chemical disk decompression

    Full Text Available Background: Transforaminal lumbar endoscopic discectomy (TLED is a minimally invasive procedure for removing lumbar disc herniations. This technique was initially reserved for herniations in the foraminal or extraforaminal region. This study concentrated on our experience regarding the outcomes and efficacy of TLED. Materials and Methods: A total of 105 patients were included in the study. The patients were retrospectively evaluated for demographic features, lesion levels, numbers of affected levels, visual analog scores (VASs, Oswestry disability questionnaire scale scores and MacNab pain relief scores. Results: A total of 48 female and 57 male patients aged between 25 and 64 years (mean: 41.8 years underwent TLED procedures. The majority (83% of the cases were operated on at the levels of L4-5 and L5-S1. Five patients had herniations at two levels. There were significant decreases between the preoperative VAS scores collected postoperatively at 6 months (2.3 and those collected after 1-year (2.5. Two patients were referred for microdiscectomy after TLED due to unsatisfactory pain relief on the 1 st postoperative day. The overall success rate with respect to pain relief was 90.4% (95/105. Seven patients with previous histories of open discectomy at the same level reported fair pain relief after TLED. Conclusions: Transforaminal lumbar endoscopic discectomy is a safe and effective alternative to microdiscectomy that is associated with minor tissue trauma. Herniations that involved single levels and foraminal/extraforaminal localizations were associated with better responses to TLED.

  6. Percutaneous treatment of intervertebral disc herniation.

    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.

    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.

    2015-03-01

    Full Text Available Incidental durotomy is a common complication of lumbar spine operations for degenerative disorders. Its incidence varies depending on several risk factors and regarding the intra and postoperative management, there is no consensus. Our objective was to report our experience with incidental durotomy in patients who were operated on for lumbar disc herniation, lumbar spinal stenosis and revision surgeries. Between 2009 and 2012, 1259 patients were operated on for degenerative lumbar disorders. For primary operations, the surgical approach was mino-open, interlamar, uni- or bilateral, as for recurrences, the removal of the compressive element was intended: the epidural scar and the disc fragment. 863 patients (67,7% were operated on for lumbar disc herniation, 344 patients (27,3% were operated on for lumbar spinal stenosis and 52 patients (5% were operated for recurrences. The operations were performed by neurosurgeons with the same professional degree but with different operative volume. Unintentional durotomy occurred in 20 (2,3% of the patients with herniated disc, in 14 (4,07% of the patients with lumbar spinal stenosis and in 12 (23% of the patients who were operated on for recurrences. The most frequent risk factors were: obesity, revised surgery and the physician’s low operative volume. Intraoperative dural fissures were repaired through suture (8 cases, by applying muscle, fat graft or by applying curaspon, tachosil. There existed 4 CSF fistulas which were repaired at reoperation. Incidental dural fissures during operations for degenerative lumbar disorders must be recognized and immediately repaired to prevent complications such as CSF fistula, osteodiscitis and increased medical costs. Preventing, identifying and treating unintentional durotomies can be best achieved by respecting a neat surgical technique and a standardized treatment protocol.

    The aim of this study was to investigate the correlation between facet tropism and spinal degenerative diseases, such as degenerative lumbar spondylolisthesis, degenerative lumbar scoliosis, and lumbar disc herniation. This study retrospectively analysed clinical data from the Department of Orthopaedics at The First Affiliated Hospital of Nanchang University. Ninety-two patients were diagnosed with lumbar spondylolisthesis, 64 patients with degenerative scoliosis, and 86 patients with lumbar disc herniation between 1 October 2014 and 1 October 2016. All patients were diagnosed using 3.0 T magnetic resonance imaging and underwent conservative or operative treatment. Facet tropism was defined as greater than a ten degree between the facet joint angles on both sides. For L3-L4 degenerative lumbar spondylolisthesis, one out of six cases had tropism compared to seven out of the 86 controls (p = 0.474). At the L4-L5 level, 17/50 cases had tropism compared to 4/42 cases in the control group (p = 0.013). At the L5-S1 level, 18/36 cases had tropism compared to 7/56 controls (p = 0.000). For degenerative lumbar scoliosis at the L1-L5 level, 83/256 cases had tropism as compared to 36/256 controls (p = 0.000). For L3-L4 lumbar disc herniation two out of eight cases had tropism compared to 14/78 controls (p = 0.625). At the L4-L5 level, 19/44 cases had tropism compared to four out of 42 controls (p = 0.001). At the L5-S1 level, 24/34 cases had tropism compared to 10/52 controls (p = 0.000). At the L4-5 and L5-S1 levels, facet tropism is associated with degenerative spondylolisthesis. In the degenerative lumbar scoliosis group, the number of case with facet tropism was significantly higher than that of the control group. Facet tropism was associated with lumbar disc herniation at the L4-5 and L5-S1 levels. Overall, in these three lumbar degenerative diseases, facet tropism is a common phenomenon.

    The change in the relative size of lumbar disc hernias and its relation to sciatic symptoms was investigated in 30 consecutive patients after conservative treatment of CT verified lumbar disc herniations. CT and clinical examination were performed before the start of therapy (CT1), as well as 3 months (CT2) and 24 months (CT3) after institution of treatment. In each patient the size of the lumbar disc herniation in relation to the size of the spinal canal was measured on identical CT slices and expressed as an index. The disc herniation index decreased markedly from CT1 to CT2 (p<0.001). Between CT2 and CT3 the reduction of the hernias was less pronounced and not significant for hernias located centrally but still significant for intermediate (p=0.03) and lateral (p=0.04) hernias. The degree of sciatic symptoms also decreased markedly between CT1 and CT2 (p=0.001) while no further improvement occurred from CT2 to CT3. There was a significant positive correlation between the improvement from sciatic pain and the reduction in the size of the individual hernia (CT1-CT2 p=0.02, CT2-CT3 p<0.001). Thus, the disc herniation index provided a method to study the anatomic effect of conservative treatment as well as a method to evaluate sciatic symptoms in relation to anatomic changes. (orig.).

    To determine whether single injections of autologous platelet-rich plasma (PRP) into symptomatic degenerative intervertebral disks will improve participant-reported pain and function. Prospective, double-blind, randomized controlled study. Outpatient physiatric spine practice. Adults with chronic (≥6 months), moderate-to-severe lumbar diskogenic pain that was unresponsive to conservative treatment. Participants were randomized to receive intradiskal PRP or contrast agent after provocative diskography. Data on pain, physical function, and participant satisfaction were collected at 1 week, 4 weeks, 8 weeks, 6 months, and 1 year. Participants in the control group who did not improve at 8 weeks were offered the option to receive PRP and subsequently followed. Functional Rating Index (FRI), Numeric Rating Scale (NRS) for pain, the pain and physical function domains of the 36-item Short Form Health Survey, and the modified North American Spine Society (NASS) Outcome Questionnaire were used. Forty-seven participants (29 in the treatment group, 18 in the control group) were analyzed by an independent observer with a 92% follow-up rate. Over 8 weeks of follow-up, there were statistically significant improvements in participants who received intradiskal PRP with regards to pain (NRS Best Pain) (P = .02), function (FRI) (P = .03), and patient satisfaction (NASS Outcome Questionnaire) (P = .01) compared with controls. No adverse events of disk space infection, neurologic injury, or progressive herniation were reported following the injection of PRP. Participants who received intradiskal PRP showed significant improvements in FRI, NRS Best Pain, and NASS patient satisfaction scores over 8 weeks compared with controls. Those who received PRP maintained significant improvements in FRI scores through at least 1 year of follow-up. Although these results are promising, further studies are needed to define the subset of participants most likely to respond to biologic intradiskal

    Full Text Available OBJECTIVE: Early detection of degenerative changes in lumbar intervertebral disc by magnetic resonance imaging in a semiautomatic classifier for prevention of degenerative disease. METHOD: MRIs were selected with a diagnosis of degenerative disc disease or back pain from January to May 2014, with a sample of 23 patients and a total of 170 disks evaluated by sagittal T2 MRI image, first evaluated by a specialist physician in training and them were introduced into the software, being the results compared. RESULTS: One hundred and fifteen discs were evaluated by a programmed semiautomatic classifier to identify MODIC changes and hernia, which produced results "normal or MODIC" and "normal or abnormal", respectively. With a total of 230 readings, of which 141 were correct, 84 were reading errors and 10 readings were undiagnosed, the semiautomatic classifier is a useful tool for early diagnosis or established disease and is easy to apply because of the speed and ease of use; however, at this early stage of development, software is inferior to clinical observations and the results were from around 65% to 60% certainty for MODIC rating and 61% to 58% for disc herniation, compared with clinical evaluations. CONCLUSION: The comparative results between the two doctors were 94 consistent results and only 21 errors, which represents 81% certainty.

  16. Overload pain but root differentiation discomfort in the lumbar spine

    Full Text Available Lumbar pain syndromes of the spine can also be referred to as the pain of the cross. These ailments have now become epidemics of our time. In literature, these pain are referred to as localized ailments that are located in the lumbar, lumbosacral, and cross-iliac areas. Cross pains are a very general term because there are a multitude of factors that cause lumbar disc herniation. This problem poses great diagnostic difficulties. [4]. The nature of these ailments is often difficult to pinpoint by the patient, but it can be the pain that describes patients from blunt, piercing, biting, baking, to those that are termed cold feeling. Keep in mind that the location of the lumbar pain symptoms varies. Patients report pain that is located throughout the lumbar-sacral area or only on one side of the spine, or occurs only in the area of the hip joints. These complaints often radiate along the lower limb. They are often the result of a lack of proper spine prevention: they contribute to this poor body posture, improper sleep positioning, as well as lack of coping skills, as well as a bad diet. In daily life, it is important to remember to do your daily activities in the correct position as well as to use prevention to avoid pain in the lumbar area.

    Lumbar vertebral body and disk infection, presenting as low back pain, is a relatively uncommon disease but is seen more often in drug addicts. Radiographs show typical changes of infection of the lumbar vertebrae and adjacent disc. Under local anesthesia a fine needle is placed, saline injected, and aspirated. The entire needle-syringe unit is submitted to the bacteriology department. Pseudomonas infection is usually found. This method of diagnosis is simple, cost effective, well accepted by the patients, and can be done on outpatients. (orig.)

    Bibliometric review of the literature. To analyze and quantify the most frequently cited papers in lumbar spine surgery and to measure their impact on the entire lumbar spine literature. Lumbar spine surgery is a dynamic and complex field. Basic science and clinical research remain paramount in understanding and advancing the field. While new literature is published at increasing rates, few studies make long-lasting impacts. The Thomson Reuters Web of Knowledge was searched for citations of all papers relevant to lumbar spine surgery. The number of citations, authorship, year of publication, journal of publication, country of publication, and institution were recorded for each paper. The most cited paper was found to be the classic paper from 1990 by Boden et al that described magnetic resonance imaging findings in individuals without back pain, sciatica, and neurogenic claudication showing that spinal stenosis and herniated discs can be incidentally found when scanning patients. The second most cited study similarly showed that asymptomatic patients who underwent lumbar spine magnetic resonance imaging frequently had lumbar pathology. The third most cited paper was the 2000 publication of Fairbank and Pynsent reviewing the Oswestry Disability Index, the outcome-measure questionnaire most commonly used to evaluate low back pain. The majority of the papers originate in the United States (n=58), and most were published in Spine (n=63). Most papers were published in the 1990s (n=49), and the 3 most common topics were low back pain, biomechanics, and disc degeneration. This report identifies the top 100 papers in lumbar spine surgery and acknowledges those individuals who have contributed the most to the advancement of the study of the lumbar spine and the body of knowledge used to guide evidence-based clinical decision making in lumbar spine surgery today. 3.

  19. Emergency Medicine Myths: Computed Tomography of the Head Prior to Lumbar Puncture in Adults with Suspected Bacterial Meningitis - Due Diligence or Antiquated Practice?

    Various sources purport an association between lumbar puncture and brainstem herniation in patients with intracranial mass effect lesions. Several organizations and texts recommend head computed tomography (CT) prior to lumbar puncture in selected patients. To review the evidence regarding the utility of obtaining head CT prior to lumbar puncture in adults with suspected bacterial meningitis. Observational studies report a risk of post-lumbar puncture brainstem herniation in the presence of intracranial mass effect (1.5%) that is significantly lower than that reported among all patients with bacterial meningitis (up to 13.3%). It is unclear from existing literature whether identifying patients with intracranial mass effect decreases herniation risk. Up to 80% of patients with bacterial meningitis experiencing herniation have no CT abnormalities, and approximately half of patients with intracranial mass effect not undergoing lumbar puncture herniate. Decision rules to selectively perform CT on only those individuals most likely to have intracranial mass effect lesions have not undergone validation. Despite recommendations for immediate antimicrobial therapy prior to imaging, data indicate an association between pre-lumbar puncture CT and antibiotic delays. Recent data demonstrate shortened door-to-antibiotic times and lower mortality from bacterial meningitis after implementation of new national guidelines, which restricted generally accepted CT indications by removing impaired mental status as imaging criterion. Data supporting routine head CT prior to lumbar puncture are limited. Physicians should consider selective CT for those patients at risk for intracranial mass effect lesions based on decision rules or clinical gestalt. Patients undergoing head CT must receive immediate antibiotic therapy. Published by Elsevier Inc.

    Indian Hedgehog (HH) has been shown to be involved in osteoarthritis (OA) in articular joints, where there is evidence that Indian HH blockade could ameliorate OA. It seems to play a prominent role in development of the intervertebral disc (IVD) and in postnatal maintenance. There is little work on IHH in the IVD. Hence the aim of the current study was to investigate the role of Indian Hedgehog in the pathology of facet joint (FJ) OA. 24 patients diagnosed with lumbar intervertebral disk herniation or degenerative spinal stenosis were included. Preoperative magnetic resonance imaging (MRI) and Osteoarthritis Research Society International (OARSI) histopathology grading system was correlated to the mRNA levels of GLI1, PTCH1, and HHIP in the FJs. The Weishaupt grading and OARSI scores showed high positive correlation (r = 0.894) (P < 0.01). MRI Weishaupt grades showed positive correlation with GLI1 (r = 0.491), PTCH1 (r = 0.444), and HHIP (r = 0.654) mRNA levels (P < 0.05 in each case). OARSI scores were also positively correlated with GLI1 (r = 0. 646), PTCH1 (r = 0. 518), and HHIP (r = 0.762) mRNA levels (P < 0.01 in each case). Cumulatively our findings indicate that Indian HH signaling is increased in OA and is perhaps a key component in OA pathogenesis and progression.

    Purpose: To show the morphological changes in postoperative lumbar spine. Material and methods: We reviewed 128 Magnetic Resonance Imaging (MRI) studies of lumbar spine. All patients complained of low back pain and had a previous lumbar surgery (1 month to 8 years). All the examinations include axial and sagittal Gadopentate-dimeglumine enhanced T1 weighted imaging. Results: Only 7,8% have the normal appearance of the postoperative lumbar spine. Epidural scar was found in 69% of examinations; of this group, 72% showed radicular involvement, and 28% had no radicular involvement. Recurrent disc herniation was found in 14,8% of exams, using gadopentate-dimeglumine to assist the differentiation from epidural fibrosis; infections like spondylodiscitis and abscess in 12,5%. Other findings included arachnoiditis, pseudomeningoceles and seromas. Conclusions: MRI is a useful method to study the postoperative lumbar spine, specially when enhanced with gadopentate-dimeglumine. Enhanced images can differentiate two of the major complication like epidural fibrosis, and recurrent disc herniation. Spondylodiscitis are important and frequent too. Although the findings of complications in our series in the postoperative lumbar spine represent 92,18 %, these not always explain the symptomatology. Therefore, the interrelation is important with the surgeon to determine which abnormalities are clinically significant. (authors) [es

    To evaluate the stenotic condition of the lumbar spinal canal, MRI was compared with myelography and with discography in 102 patients, all of whom underwent surgical exploration. Various pathologic conditions were studied including 50 cases of herniated nucleus pulposus, 39 cases of lumbar canal stenosis (central, peripheral type or combined type), and 13 cases of spondylolisthesis (degenerative, spondylolytic, and dysplastic type). High correlation was detected between the T2 weighted mid-sagittal image of the thecal sac and the lateral view of a full-column myelogram, but subtle changes such as adhesive changes, or redundancy, or anomalous changes of the nerve roots were more clearly demonstrated on myelograms than on MRI. Actually some of these changes could not be detected on MRI. The degrees of disc degeneration were classified into five grades according to the signal intensity and the irregularity of the disc on the T2-weighted image. The MRI evaluation of disc degeneration in this series was similar to that of the discography. However, MRI could not replace discography for identifying the source of pain in symptomatic patients. Although MRI might be the imaging modality for diagnostic screening and for detecting stenotic conditions of the lumbar spinal canal, it will not be able to replace myelography and/or discography for determining indication for surgery and preferred surgical approach.

    Full Text Available Abstract Background The to date evidence for a dose-response relationship between physical workload and the development of lumbar disc diseases is limited. We therefore investigated the possible etiologic relevance of cumulative occupational lumbar load to lumbar disc diseases in a multi-center case-control study. Methods In four study regions in Germany (Frankfurt/Main, Freiburg, Halle/Saale, Regensburg, patients seeking medical care for pain associated with clinically and radiologically verified lumbar disc herniation (286 males, 278 females or symptomatic lumbar disc narrowing (145 males, 206 females were prospectively recruited. Population control subjects (453 males and 448 females were drawn from the regional population registers. Cases and control subjects were between 25 and 70 years of age. In a structured personal interview, a complete occupational history was elicited to identify subjects with certain minimum workloads. On the basis of job task-specific supplementary surveys performed by technical experts, the situational lumbar load represented by the compressive force at the lumbosacral disc was determined via biomechanical model calculations for any working situation with object handling and load-intensive postures during the total working life. For this analysis, all manual handling of objects of about 5 kilograms or more and postures with trunk inclination of 20 degrees or more are included in the calculation of cumulative lumbar load. Confounder selection was based on biologic plausibility and on the change-in-estimate criterion. Odds ratios (OR and 95% confidence intervals (CI were calculated separately for men and women using unconditional logistic regression analysis, adjusted for age, region, and unemployment as major life event (in males or psychosocial strain at work (in females, respectively. To further elucidate the contribution of past physical workload to the development of lumbar disc diseases, we performed lag

    Internal hernias have an overall incidence of less than 1% and are difficult to diagnose clinically due to their nonspecific presentation. Most internal hernias present as strangulating closed-loop obstruction and delay in surgical intervention is responsible for a high mortality rate (49%). We present a case of ileal herniation through the foramen of Winslow. A 29-year-old previously healthy female presented with acute onset right upper quadrant pain, abdominal fullness, and nausea. The pain was sudden in onset and began shortly after a dinner party where she consumed larger portions of food. Laboratory investigations revealed mild leukocytosis with left shift. Dual-phase multi-detector computed tomography disclosed herniation of the small bowel into the lesser sac. The patient underwent an emergency median laparotomy that revealed ileal herniation through the foramen of Winslow. Adhesiolysis and manual reduction of the bowel was performed, and the reduced bowel showed only congestive changes. The postoperative recovery was uneventful and the patient was discharged on the third postoperative day. Risk factors for internal herniation still remain unclear, although excessively mobile bowel loops and an enlarged foramen of Winslow have been described. Our case demonstrated that overeating could be an additional risk factor for internal herniation. We describe our clinical and radiology findings, as well as surgical management. Due to the high rates of morbidity and mortality, it is imperative that clinicians be aware of the possible risks factors for internal herniation. Internal hernias should be included in the differential diagnosis of small bowel obstruction so that appropriate steps can be made in the work-up of these patients, followed by timely surgical intervention.

    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.

    To examine epidural fat images, lumbar magnetic resonance (MR) images were retrospectively reviewed in a total of 103 patients with surgically proven lumbar disc herniation (DH, n=57) and lumbar canal stenosis (LCS, n=46). Epidural fat images consisted of middorsal epidural fat (MDF), paramedian ventral fat (PVF) and intervertebral foraminal fat (IFF) ones. In the group of DH, the thickness of MDF image did not correlate with that of subcutaneous fat, suggesting that epidural fat was not affected by body fat. From the pathophysiological point of view, decrease and disappearance of MDF images correlated with compression of the epidural canal. Decrease and disappearance of PVF images lead to suspicious compression of the traversing root. In addition, asymmetrical PVF images were useful for the bilateral diagnosis of herniation. Abnormal findings of IFF images were suggestive of compression of the exiting nerve root at the intervertebral foramen. This was also seen frequently at the non-responsible level in patients over the age of 50. Degenerative and sequentrated spondylolistheses in the group of LCS were more frequently associated with a higher incidence of abnormal findings of IFF images, suggesting the presence of existing nerve root compression.

    This paper reports low back symptoms of 1,500 school children (14 years old) evaluated with a questionnaire and with a standardized clinical examination. Forty children who complained of recurrent and/or persistent low back pain and 40 matching symptomless controls were randomly chosen to undergo MR imaging of the lumbar spine. Premature disk degeneration was seen in 25.5% of asymptomatic children and in 40% of those with low back pain. The difference was statistically not significant. Disk degeneration is a surprisingly frequent MR finding in symptomless children. Premature disk degeneration may be the cause of low back pain in some children but is not always symptomatic in childhood

    The authors report radiological findings in 13 cases of avulsion of the posterior lumbar apophyseal ring. The lesion affected young adults in 10 cases and adolescents in 3 cases. The lesion involved the inferior endplate of L4 in 11, and of L5 in 2 patients. 6 patients presented with unilateral sciatica, 3 with bilateral sciatica, and 4 with low back pain. Acute spinal trauma was evident only in 2 adolescents. Radiological recognition of the lesion was possible on plain films in 9 cases. CT demonstrates association of avulsion of the posterior vertebral apophyseal ring and herniated disc in all cases. Avulsion of the posterior apophyseal ring has to be differentiated from posterior longitudinal ligament, annulus, or herniated disc calcifications, as well as from posterior degenerative ridge osteophytes. Controversy about physiopathology of the lesion remains: Weakness of the apophyseal ring during childhood and in patients with Scheuermann's disease may explain avulsion of the apophyseal ring in association with median disc herniation.

    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

    Preoperative CT was done in 39 patients with lumbar canal stenosis. Marked symmetrical narrowing of the whole vertebral canal was seen in the group with nervous symptoms in the cauda equina. Deformed bilateral intervertebral joints were seen in the group with both nervous symptoms in the cauda equina and radicular sciatica. The lateral recess on the affected side was markedly narrowed by the projection of the upper and lower joints and herniation. In the group with radicular sciatica, the vertebral canal itself was not so narrowed, but the unilateral intervertebral joint was extremely deformed, causing a narrowing of the lateral recess. There were large differences in the angle of the left and right intervertebral joints. (Namekawa, K)

    The authors describe an unusual case of a fatal iatrogenic fourth lumbar artery injury during left hemilaminectomy in a 38-year-old woman. At autopsy, gross inspection revealed hemoperitoneum with 1,800 ml of free blood and massive retroperitoneal extravasation. A laceration with irregular and jagged margins was detected on the wall of the fourth right lumbar artery. The autopsy and the post-mortem TC investigations demonstrated that wrong-level hemilaminectomy was performed for the herniated disc.

    The computer tomography is useful in evaluation of bony structures and adjacent soft tissues of the lumbar spine. Recently, the multiplanar reconstruction of lumbar spine of CT of significant value for the anatomical localization and for the myelographic and surgical correlation. We observed 177 cases of lumbar spine CT, who complains of spinal symptom, during the period from Dec. 1982 to Aug. 1984. The results were as follows: 1. The sex distribution of cases were 113 males and 44 females. The CT diagnosis showed 152 cases of herniated lumbar disc, 15 cases of degenerative disease, 5 cases of spine tbc., 3 cases of spine trauma and 2 cases of meningocele. 2. CT findings of herniated disc were as follows: focal protrusion of posterior disc margin and obliteration of anterior epidural fat in all cases, indentation on dural sac in 92 cases (60.5%) soft tissue mass in epidural fat in 85 cases (55.9%), compression or displacement of nerve root sheath in 22 cases(14.4%). 3. Sites of herniated lumbar disc were at L4-L5 level in 100 cases(59.1%) and at L5-S1 level in 65 cases (38.4%). Location of it were central type in 70 cases(41.1%), left-central type in 46 cases (27.2%), right-central type in 44 cases(26.0%) and lateral type in 9 cases (5.1%). 4. The sagittal reconstruction images were helpful in evaluating neural foramina, size of disc bluge into spinal canal, especially at L5-S1, and patients with spondylolisthesis. The coronal reconstruction images were the least informative, although they contributed to the evaluation of lumbar nerve roots of course, the axial CT scans were the most sensitive and specific.

    To evaluate the sonographic features and appearance time of the physiologic midgut herniation early in pregnancy. Sonograms of 87 features ranging from 7 to 13 weeks were obtained over a 2-month period. The presence or absence, the size and echogenecity of the physiologic midgut herniation were evaluate on each examination. Disappearance of the midgut herniation was confirmed on follow-up sonogram at 13-20 weeks, 3-12 weeks after the first sonogram. The results were analyzed in terms of appearance or disappearance time of midgut herniation. In all cases of physiologic midgut herination, an echogenic mass measuring 0.4-0.7 cm wa demonstrated within the base of the umbilical cord at its insertion into the fetal abdomen. This herniation was detected in 3/6 cases (50%) at 8 weeks, in 15/16 cases (94%) at 9 weeks, in 22/24 cases (92%) at 10 weeks and in 12/27 cases (44%) at 11 weeks gestation. None of the features studied at 7 weeks and 12 weeks had a midgut herniation. Sonographic findings of a 0.4-0.7 cm sized echogenic mass within the base of the umbilical cord which appears from 8 weeks to 12 weeks pregnancy represent physiologic midgut herniation in early pregnancy and should not be confused with pathologic ventral wall defected such as omphalocele or gastroschisis.

    Despite decompressive hemicraniectomy (DHC), progressive herniation resulting in death has been reported following middle cerebral artery (MCA) strokes. We aimed to determine the surgical parameters measured on brain computed tomography (CT) scan that are associated with progressive herniation despite DHC in large MCA strokes. Retrospective chart review of medical records of patients with malignant hemispheric infarction who underwent DHC for cerebral edema was performed. Infarct volume was calculated on CT scans obtained within 24 hours of ictus. Radiological parameters of craniectomy bone flap size, brain volume protruding out of the skull, adequate centering of the craniectomy over the stroke bed, and the infarct volume outside the craniectomy bed (volume not centered [VNC]) were measured on the postoperative brain CT. Of 41 patients who underwent DHC, 7 had progressive herniation leading to death. Radiographic parameters significantly associated with progressive herniation included insufficient centering of craniectomy bed on the stroke bed (P = .03), VNC (P = .011), additional anterior cerebral artery infarction (P = .047), and smaller craniectomy length (P = .05). Multivariate logistic regression analysis for progressive herniation using craniectomy length and VNC as independent variables demonstrated that a higher VNC was significantly associated with progressive herniation despite surgery (P = .029). In large MCA strokes, identification of large infarct volume outside the craniectomy bed was associated with progressive herniation despite surgery. These results will need to be verified in larger prospective studies. Copyright © 2018 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Objective. The objective of this study was to review the problem of lumbar gibbus in children with storage diseases and bone dysplasias utilizing plain films and MR imaging. Materials and methods. Clinical histories and radiographic images in five patients with storage diseases [four mucopolysaccharidosis (MPS) and one mucolipidosis] and two with achondroplasia were reviewed. The International Skeletal Dysplasia Registry (Los Angeles, Calif.), surveyed for all patients with lumbar gibbus and skeletal dysplasias, provided 12 additional cases. Results. All patients had localized gibbus of the upper lumbar spine, characterized by anterior wedging and posterior displacement of the vertebrae at the apex of the curve, producing a beaked appearance. The curve, exaggerated in the sitting or standing position, was most severe in the two patients with MPS-IV (one of whom died). Both developed severe neurologic signs and symptoms requiring surgical intervention. In four patients, MR images demonstrated the apex of the curve to be at or below the conus. Two patients demonstrated anterior herniation of the intervertebral discs at the apex of the curve, though the signal intensity of the intervertebral discs was normal. Conclusion. Lumbar gibbus has important neurologic and orthopedic implications, and is most severe in patients with MPS. The etiology of the gibbus with vertebral beaking is multifactorial and includes poor truncal muscle tone, weight-bearing forces, growth disturbance and anterior disc herniation. The curve is generally at or below the conus. Neurologic complications are unusual, although orthopedic problems can arise. Due to their longer survival, patients with achondroplasia or Morquio`s disease are more vulnerable to eventual gibbus-related musculoskeletal complications. (orig.). With 6 figs., 2 tabs.

The curve, exaggerated in the sitting or standing position, was most severe in the two patients with MPS-IV (one of whom died). Both developed severe neurologic signs and symptoms requiring surgical intervention. In four patients, MR images demonstrated the apex of the curve to be at or below the conus. Two patients demonstrated anterior herniation of the intervertebral discs at the apex of the curve, though the signal intensity of the intervertebral discs was normal. Conclusion. Lumbar gibbus has important neurologic and orthopedic implications, and is most severe in patients with MPS. The etiology of the gibbus with vertebral beaking is multifactorial and includes poor truncal muscle tone, weight-bearing forces, growth disturbance and anterior disc herniation. The curve is generally at or below the conus. Neurologic complications are unusual, although orthopedic problems can arise. Due to their longer survival, patients with achondroplasia or Morquio's disease are more vulnerable to eventual gibbus-related musculoskeletal complications. (orig.). With 6 figs., 2 tabs

    To report our results about minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) with bilateral pedicle screw fixation, in patients with degenerative lumbosacral spine disease. To describe the indications, surgical technique and results of a consecutive series of 40 patients undergone MI-TLIF. Despite the limited number of clinical studies, published data suggest tremendous potential advantages of this technique. Forty patients with radiological findings of degenerative lumbosacral spine disease were undergone MI-TLIF between July 2012 and January 2015. Clinical outcomes were assessed by means of Oswestry Disability Index (ODI) and Health Survey Scoring (SF36) before surgery and at first year follow-up. Furthermore, the following parameters were retrospectively reviewed: age, sex, working activity, body mass index (BMI), type of degenerative disease, number of levels of fusion, operative time, blood loss, length of hospital stay. Average operative time was of 230 minutes, mean estimated blood loss 170 mL, average length of hospital stay 5 days. The ODI improved from a score of 59, preoperatively, to post-operative score of 20 at first year follow-up. Average SF36 score increased from 36 to 54 (Physical Health) and from 29 to 50 (Mental Health) at first year outcome evaluation. MI-TLIF with bilateral pedicle screw fixation is an excellent choice for selected patients suffering from symptomatic degenerative lumbosacral spine disease, especially secondary to recurrent disk herniations.

    The lumbar facet disease is a frequently overlooked cause of sciatic pain, but the lumbar facet joints are well-recognized source of low back pain and radiating leg pain which can be confused with sciatica due to herniated disc. We measured the angulation of the facet joints on axial spine CT films in 149 cases which contains 41 normal group and 108 abnormal group and studied the relationship between the angulation and degeneration of the facets, the asymmetry of each sided facets and facet degeneration, the asymmetry and disc protrusion, and the asymmetry and annular bulging of the disc. The results were as follows: 1. Facet angulation in abnormal group were more sagittally oriented than the normal group. 2. The angulation of right facet was more sagittally oriented than the left in L4-5 level of abnormal group. 3. Degeneration of facet joints occur asymmetrically, and the more facet joint degenerates, the more it orients sagittally, particularly in L4-5. 4. Asymmetry in facet joint degeneration and unilateral disc protrusion of L5-SI level is greater than the normal gro0008.

    In order to evaluate the stenotic condition of lumbar spinal canal, MRI was compared with myelogram and with discogram in 82 patients, all of whom underwent surgical exploration. Pathologic conditions were studied including herniated nucleus pulposus in 36, lumbar canal stenosis (central, peripheral portion, combined) in 35, and spondylisthesis (degenerative, spondylolytic, dysplastic) in 11. Correlation between T2 mid-sagittal image of the thecal sac and profile view of full-column myelogram was very high, but fine parts such as adhesive change or redundancy or anomalous condition of nerve roots were more clearly observed on myelogram than on MRI. And some of them were not detected on MRI. The stage of disc degeneration was classified in 5 grades according to signal intensity and irregularity of the disc on T2-weighted image. The evaluation of disc degeneration was similar to discogram. But MRI will not replace discography for identifying the source of pain in symptomatic patients. Although MRI is the most important imaging modality to diagnostic screening and to post-operative evaluation of the stenotic condition, determination of the strict indication and the method of the operation will need myelogram and/or discogram and so on.

    Full Text Available We report on a patient who presented with left flank pain for 6 months. Computed tomography and intravenous urography revealed left ureterosciatic herniation with severe hydronephrosis. Antegrade placement of the ureteral double-J stent was performed and her symptoms subsequently subsided. These symptoms recurred after the removal of the stent 1 year later with persistent hydronephrosis and herniation. We performed laparoscopic ureterolysis, ureteral fixation to psoas muscle, and sciatic hernia repair with hyaluronan-containing mesh. The result was encouraging and the follow-up image at 6 months showed no hydronephrosis and no ureteral herniation.

    Muscle herniation can be defined as protrusion of a portion of muscle through an acquired or congenital defect of enclosing fascia. Although it is usually a cosmetic problem, it can lead to local pain and tenderness after prolonged exertion. In this report, we present a case of flexor digitorum superficialis muscle herniation in a 58-year-old man. The radiographic, ultrasonographic and magnetic resonance imaging findings are described with dynamic examination, permitting demonstration of muscle herniation through the fascial defect during muscle contraction.

Physical examination showed small bulge at the level of the herniation that was most obvious with coughing. CT scan of chest done 2 months ago showed 2. 5 cm pulmonary hernia identified at the left 7-8 costal interspace (Figures 1 and 2. This was thought to have resulted from an open lung biopsy of his left lung done 4 years before presentation to evaluate for acute respiratory failure or chest tube insertion at same site 3 years prior to presentation for treatment of a pneumothorax. Surgical repair was done with round Bard Kugel hernia patch. His symptoms resolved after the procedure.

Various modalities of treatments are utilized in managing discogenic and axial low back pain including epidural injections. However, there is a paucity of evidence regarding the effectiveness, indications, and medical necessity of any treatment modality utilized for managing axial or discogenic pain, including epidural injections. In an interventional pain management practice in the US, a randomized, double-blind, active control trial was conducted. The objective was to assess the effectiveness of lumbar interlaminar epidural injections of local anesthetic with or without steroids for managing chronic low back pain of discogenic origin. However, disc herniation, radiculitis, facet joint pain, or sacroiliac joint pain were excluded. Two groups of patients were studied, with 60 patients in each group receiving either local anesthetic only or local anesthetic mixed with non-particulate betamethasone. Primary outcome measures included the pain relief-assessed by numeric rating scale of pain and functional status assessed by the, Oswestry Disability Index, Secondary outcome measurements included employment status, and opioid intake. Significant improvement or success was defined as at least a 50% decrease in pain and disability. Significant improvement was seen in 77% of the patients in Group I and 67% of the patients in Group II. In the successful groups (those with at least 3 weeks of relief with the first two procedures, the improvement was 84% in Group I and 71% in Group II.

    To examine associations between imaging characteristics of compressive lesions and patient outcomes after lumbar transforaminal epidural steroid injections (TFESIs) stratified by steroid formulation (solution versus suspension). Retrospective observational study, academic radiology practice. A 516-patient sample was selected from 2,634 consecutive patients receiving lumbar TFESI for radicular pain. The advanced imaging study(s) preceding sampled TFESI were reviewed. Compressive lesions were described by a) nature of the lesion [disc herniation, fixed stenosis, synovial cyst, epidural fibrosis, no lesion] b) degree of neural compression [4 part scale], and c) presence of a tandem lesion. Associations between 2-month categorical outcomes (responder rates for pain, functional recovery) and imaging characteristics, stratified by steroid formulation, were examined with chi-squared tests of categorical outcomes and multivariable logistic regression models. Disc herniation patients had more responders for functional recovery than patients with fixed lesions (54% versus 38%, P = 0.01). Patients with fixed lesions receiving steroid solution (dexamethasone) had more responders for pain relief, with a similar trend for functional recovery, than patients receiving suspensions (59% versus 40%, P = 0.01). Outcomes for patients with fixed lesions treated with dexamethasone were not statistically different from those for disc herniation patients. Patients with single compressive lesions had more responders than those with tandem lesions (55% versus 41%, P = 0.03). In the entire sample, outcomes for disc herniations were more favorable than for fixed lesions. However, fixed lesions treated with dexamethasone had outcomes indistinguishable from disc herniations. Single lesions had better outcomes than tandem lesions. © 2016 American Academy of Pain Medicine. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.

  15. Clinical And Surgical Anatomy Of Lumbar Hernia: A Review

    Full Text Available Lumbar hernia is defined as the presence of failure in the transverse fascia or in the aponeurosis of the transverse abdominal muscle that results in the extrusion of intra or extra peritoneal organs through the discontinuity of the postero lateral abdominal wall. The aim of this study was to conduct a methodical review of the anatomy of the hernia form grynfelt dated from 2006 to 2017. For this, we performed a bibliographic review by means of electronic databases like SciELO, PubMed, Science Direct, LILACS and Bireme to get better approach to the subject. It has been found that the lumbar hernia is a disease little known by doctors whose diagnostics are often performed in the wrong way and for surgical correction needs a good anatomical knowledge. Lumbar hernias, although rare, must be taken into account, since ischemia of herniated intestinal segments can lead to the death of the patient, especially in the elderly. Knowledge about the anatomy of the lumbar region is of vital importance because it makes surgery safe and reduces risks of complications and recidivating of the hernia.

    Anatomic and X-ray correlations in 31 postmortem unfixed specimens of the vertebral lumbar region have shown that in the diagnosis of disk prolapse and commissural processes in the anterior epidural space roentgenopositive contrast substances are not much superior to roentgenonegative ones. Functional pneumoepidurogaphy used in 102 patients with lumbar osteochondrosis helped to reveal intervertebral disk prolapse at all the stages of degenerative affection, to evaluate function of the disk-ligamentous apparatus and to specify the nature of a pathological process in the epidural space.

    SUMMARY - 'Idiopathic' herniation of the brain is a rare entity previously reported in 13 cases. It may be incidentally encountered in neuroimaging studies acquired for various clinical indications. We herein describe two cases of idiopathic brain herniation that were incidentally diagnosed. A 12-year-old boy presented with a six-month history of daytime sleepiness and sudden spells of sleep. Herniation of the left inferior temporal gyrus was revealed in MRI acquired with the suspicion of epilepsy. His overnight polysomnogram and multiple sleep latency tests were compatible with the diagnosis of narcolepsy. The other case, a two-year-old girl, was transferred from an outside hospital due to partial seizures with the fever. Herniation of the precuneal gyrus was encountered in MRI acquired after controlling her seizures with the initiation of phenytoin. The brain herniations of both patients were considered to be inconsistent with their medical conditions, so that they were symptom-free with only medical treatment for following three and six months, respectively. This is a rare presentation of idiopathic brain herniation as an incidental finding that accompanied narcolepsy and epilepsy. Awareness of this entity would avoid excessive surgical and medical treatments.

  19. 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

    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)

    Symptom of herpes zoster is sometimes difficult to distinguish from sciatica induced by spinal diseases, including lumbar disc herniation and spinal canal stenosis. Here we report a case of sciatica mimicking lumbar canal stenosis. A 74-year-old Chinese male patient visited our hospital for left-sided sciatic pain upon standing or walking for 5 min of approximately 1 month's duration. At the first visit to our hospital, there were no skin lesions. A magnetic resonance imaging showed spinal canal stenosis between the 4th and 5th lumbar spine. Thus, we diagnosed the patient with sciatica induced by spinal canal stenosis. We considered decompression surgery for the stenosis of 4th and 5th lumbar spine because conservative therapy failed to relieve the patient's symptom. At that time, the patient complained of a skin rash involving his left foot for several days. A vesicular rash and erythema were observed on the dorsal and plantar surfaces of the great toe and lateral malleolus. The patient was diagnosed with herpes zoster in the left 5th lumbar spinal nerve area based on clinical findings, including the characteristics of the pain and vesicular rash and erythema in the 5th lumbar spinal dermatome. The patient was treated with famciclovir (1,500 mg/day) and non-steroidal anti-inflammatory drugs. After 1 week of medication, the skin rash resolved and pain relief was obtained. In conclusion, spinal surgeons should keep in mind herpes zoster infection as one of the possible differential diagnoses of sciatica, even if there is no typical skin rash.

    Full Text Available Background: Lumbar disc herniation is a major cause of back pain and sciatica. The surgical management of lumbar disc prolapse has evolved from exploratory laminectomy to percutaneous endoscopic discectomy. Percutaneous endoscopic discectomy is the least invasive procedure for lumbar disc prolapse. The aim of this study was to analyze the clinical outcome, quality of life, neurologic function, and complications. Materials and Methods: One hundred patients with lumbar disc prolapse who were treated with percutaneous endoscopic discectomy from May 2012 to January 2014 were included in this retrospective study. Clinical followup was done at 1 month, 3 months, 6 months, 1 year, and at yearly interval thereafter. The outcome was assessed using modified Macnab′s criteria, visual analog scale, and Oswestry Disability Index. Results: The mean followup period was 2 years (range 18 months - 3 years. Transforaminal approach was used in 84 patients, interlaminar approach in seven patients, and combined approach in nine patients. An excellent outcome was noted in ninety patients, good outcome in six patients, fair result in two patients, and poor result in two patients. Minor complications were seen in three patients, and two patients had recurrent disc prolapse. Mean hospital stay was 1.6 days. Conclusions: Percutaneous endoscopic lumbar discectomy is a safe and effective procedure in lumbar disc prolapse. It has the advantage that it can be performed on a day care basis under local anesthesia with shorter length of hospitalization and early return to work thus improving the quality of life earlier. The low complication rate makes it the future of disc surgery. Transforaminal approach alone is sufficient in majority of cases, although 16% of cases required either percutaneous interlaminar approach or combined approach. The procedure definitely has a learning curve, but it is acceptable with adequate preparations.

    Degenerative lumbar spine diseases, i.e., sacrolumbar stenosis, intervertebral disk degeneration and protrusion and spondylosis deformans of the canine lumbar spine were studied in eleven canine patients and three healthy controls using radiography and 0.02 T and 0.04 T low field magnetic resonance imaging. The T1 and T2 weighted images were obtained in sagittal and transverse planes. The loss of hydration of nucleus pulposus, taken as a sign of degeneration in the intervertebral disks, could be evaluated in both T1 and T2 weighted images. As a noninvasive method magnetic resonance imaging gave more exact information about the condition of intervertebral disks than did radiography. Sacrolumbar stenosis and compression of the spinal cord or cauda equina and surrounding tissue could be evaluated without contrast medium

    Foraminal and extra-foraminal disc herniations comprise up to 11.7% of all lumbar disc herniations. Facetectomy, which had been the classic approach, is now recognized as cause of pain and instability after surgery. Otherwise, posterior lateral approaches through a trans-muscular or a para-muscular technique offer no significant damage to key structures for spinal stability. The surgical anatomy of these approaches has already been described, but they were not compared. In order to quantify the angle of vision towards the intervertebral foramen offered by each technique, 12 fresh cadavers were dissected and studied regarding these approaches. The angle presented by trans-muscular approach was wider in all studied lumbar levels. Surgery through the trans-muscular approach is performed with a better working angle, requiring a smaller resection of surrounding tissues. Therefore, minor surgical trauma can be expected. Our measurements support previously published data that point the trans-muscular approach as the best surgical option.

    The most common causes of pain following lumbar spinal fusions are residual herniation, or foraminal fibrosis and foraminal stenosis that is ignored, untreated, or undertreated. The original surgeon may advise his patient that nothing more can be done in his opinion that the nerve was visually decompressed by the original surgery. Post-operative imaging or electrophysiological assessment may be inadequate to explain all the reasons for residual or recurrent symptoms. Treatment of failed lumbar spinal fusions by repeat traditional open revision surgery usually incorporates more extensive decompression causing increased instability and back pain. The authors, having limited their practice to endoscopic surgery over the last 10 years, report on their experience gained during that period to relieve pain by transforaminal percutaneous endoscopic revision of lumbar spinal fusions. To assess the effectiveness of transforaminal percutaneous endoscopic discectomy and foraminoplasty in patients with pain after lumbar spinal fusion. Retrospective study. Inpatient surgery center. Sixteen consecutive patients with pain after lumbar spinal fusions presenting with back and leg pain that had supporting imaging diagnosis of foraminal stenosis and/or residual/recurrent disc herniation, or whose pain complaint was supported by relief from diagnostic and therapeutic injections, were offered percutaneous transforaminal endoscopic discectomy and foraminoplasty over a repeat open procedure. Each patient sought consultation following a transient successful, partially successful or unsuccessful open lumbar spinal fusions treatment for disc herniation or spinal stenosis. Endoscopic foraminoplasty was also performed to either decompress the bony foramen in the case of foraminal stenosis, or to allow for endoscopic visual examination of the affected traversing and exiting nerve roots in the axilla. The average follow-up time was 30.3 months, minimum 12 months. Outcome data at each visit

    Gas production as a part of disk degeneration can occur but rarely causes nerve compression syndromes. Few cases have been reported in which lumbar intraspinal epidural gas cause nerve root compression symptoms. We present 12 cases of gas collection in the spinal canal that were presented to the orthopaedic out-patient department with symptoms of low back pain and sciatica. CT showed the presence of free epidural gas collections adjacent to or over the affected nerve roots. Relief of symptoms was noted with the change of positions, lying down or sleeping. In this study, we conclude that the presence of lumbar intraspinal epidural gas that causes radicular compressing phenomena, can be easily detected with the use of CT.

    Gas production as a part of disk degeneration can occur but rarely causes nerve compression syndromes. Few cases have been reported in which lumbar intraspinal epidural gas cause nerve root compression symptoms. We present 12 cases of gas collection in the spinal canal that were presented to the orthopaedic out-patient department with symptoms of low back pain and sciatica. CT showed the presence of free epidural gas collections adjacent to or over the affected nerve roots. Relief of symptoms was noted with the change of positions, lying down or sleeping. In this study, we conclude that the presence of lumbar intraspinal epidural gas that causes radicular compressing phenomena, can be easily detected with the use of CT

    Full Text Available People around the world suffer chronic lower back pain. Because spine imaging often does not explain the degree of perceived pain reported by patients, the role of the processing of nociceptor signals in the brain as the basis of pain perception is gaining increased attention. Modern neuroimaging techniques (including functional and morphometric methods have produced results that suggest which brain areas may play a crucial role in the perception of acute and chronic pain. In this study, we examined twelve patients with chronic low back pain and sciatica, both resulting from lumbar disc herniation. Structural magnetic resonance imaging (MRI of the brain was performed one day prior to and about four weeks after microsurgical lumbar discectomy. The subsequent MRI revealed an increase in gray matter volume in the basal ganglia but a decrease in volume in the hippocampus, which suggests the complexity of the network that involves movement, pain processing, and aspects of memory. Interestingly, volume changes in the hippocampus were significantly correlated to preoperative pain intensity but not to the duration of chronic pain. Mapping structural changes of the brain that result from lumbar disc herniation has the potential to enhance our understanding of the neuropathology of chronic low back pain and sciatica and therefore may help to optimize the decisions we make about conservative and surgical treatments in the future. The possibility of illuminating more of the details of central pain processing in lumbar disc herniation, as well as the accompanying personal and economic impact of pain relief worldwide, calls for future large-scale clinical studies.

    This study aimed to analyze the clinical features of lumbar hernia reported in South Korea and compare these features with those reported in foreign literature. From January 1968 through December 2013, 13 cases reported in South Korea were included in the study. The variables compared were age, sex, main symptoms at hospital visit, etiology, location, herniated contents, lateralization, defect size, diagnostic methods, surgical methods, surgical opinions, and recurrence. In the South Korean cases, women outnumbered men (3.3:1) and no significant differences were found in the herniated side (left:right, 1.1:1). In contrast, in the foreign cases, men outnumbered women (3:1) and left-sided hernia was dominant (2:1). Moreover, in most of the foreign cases, patients were aged 50-70 years, whereas in the South Korean cases, none of the patients were in their 50 s. However, no substantial differences were found in etiology, anatomical locations, symptoms, and herniated contents. This research revealed that few clinical features of lumbar hernias in South Korea differ from those reported in foreign literature. Thirteen cases were analyzed in the present study, and results obtained from such a small sample size cannot be generalized with certainty. Therefore, more cases should be collected for a definitive analysis. Despite this limitation, this study is important because it is the first attempt to collect and analyze the clinical features of lumbar hernia in South Korea. This study will serve as a basis for future studies investigating the clinical features of lumbar hernia cases in South Korea.

    Full Text Available Herniation of nucleus pulposus leading to leg pain is the commonest indication for lumbar spine surgery. However, there is no consensus when to stop conservative treatment and when to consider for surgery. A systematic review of literature was done to find a consensus on the issue of when should surgery be performed for herniation of nucleus pulposus in lumbar spine was conducted. Electronic database searches of Medline, Embase and Pubmed Central were performed to find articles relating to optimum time to operate in patients with herniation of nucleus pulposus in lumbar spine, published between January 1975 and 10 December 2012. The studies were independently screened by two reviewers. Disagreements between reviewers were settled at a consensus meeting. A scoring system based on research design, number of patients at final followup, percentage of patients at final followup, duration of followup, journal impact factor and annual citation index was devised to give weightage to Categorize (A, B or C each of the articles. Twenty one studies fulfilled the criteria. Six studies were of retrospective design, 13 studies were of Prospective design and two studies were randomized controlled trials. The studies were categorized as: Two articles in category A (highest level of evidence, 12 articles in category B (moderate level of evidence while seven articles in Category C (poor level of evidence. Category A studies conclude that duration of sciatica prior to surgery made no difference to the outcome of surgery in patients with herniation of nucleus pulposus in the lumbar spine. Ten out of 12 studies in Category B revealed that longer duration of sciatica before surgery leads to poor results while 2 studies conclude that duration of sciatica makes no difference to outcome. In category C, five studies conclude that longer duration of sciatica before surgery leads to poor outcome while two studies find no difference in outcome with regards to duration of

    There are many different reasons why patients could be experiencing pain in the gluteal area. Previous studies have shown an association between radicular low back pain (LBP) and gluteal pain (GP). Studies locating the specific level responsible for gluteal pain in lumbar disc hernias have rarely been reported. All patients with lumbar disc herniation (LDH) in the Kanghua hospital from 2010 to 2014 were recruited. All patients underwent a lumbar spine MRI to clarify their LDH diagnosis, and patients were allocated to a GP group and a non-GP group. To determine the cause and effect relationship between LDH and GP, all of the patients were subjected to percutaneous endoscopic lumbar discectomy (PELD). A total of 286 cases were included according to the inclusive criteria, with 168 cases in the GP group and 118 cases in the non-GP group. Of these, in the GP group, 159 cases involved the L4/5 level and 9 cases involved the L5/S1 level, while in the non-GP group, 43 cases involved the L4/5 level and 48 cases involved the L5/S1 level. PELD was performed in both groups. Gluteal pain gradually disappeared after surgery in all of the patients. Gluteal pain recrudesced in a patient with recurrent disc herniation (L4/5). As a clinical finding, gluteal pain is related to low lumbar disc hernia. The L4/5 level is the main level responsible for gluteal pain in lumbar disc hernia. No patients with gluteal pain exhibited involvement at the L3/4 level.

    In order to assess the incidence and radiologic findings of herniation pit of the femur neck in Korean. In 152 macerated femurs of 88 cadavers, and randomly selected 115 hips of 70 patients, the presence of herniation pit was determined by using fluoroscopy and radiography. It was then examined by CT for inspection of overlying surface and its opening was confirmed by inserting thin steal wire under the fluoroscopic guidance. Seventeen herniation pits in 15 macerated femurs of 13 cadavers were noted. (14.8%, 13/88). Two of 13 individuals showed bilaterality. All lesions were found only in males. Six herniation pit in 6 femurs of 6 patients (8.6%, 6/70) were also noted. All lesions were on anterosuperior aspect of femur neck. Plain radiographs of macerated femurs revealed well marginated and thin sclerosis in 15 lesions. Of all 23 lesions, CT showed cortical breakdown in 3, and overlying cortical thickening in 8. In 15 macerated femurs, roughed area of cortex was found in anterosuperior aspect of femur in all cases, and tiny openings(diameter less than 1 mm) related to cystic lesions were confirmed in 9 lesions. The incidence of herniation pits was 14.8% in 88 cadaver, and 8.6% in 70 patients. All were males

    Gynecomastia is a common disorder observed in male plastic surgery patients. Treatment options may include observation, surgical excision, or liposuction techniques. Congenital herniated nipple is a more rare condition, especially in male patients. We present the case of a 12-year-old boy with bilateral gynecomastia and herniated nipple-areolar complexes. A staged repair was undertaken in this patient with grade 2 gynecomastia. The first operation was ultrasonic liposuction bilaterally, yielding 200 mL of aspirate from the left and 400 mL on the right, to correct the gynecomastia. The second procedure, performed 6 months later, was a bilateral periareolar mastopexy to repair the herniated nipple-areolar complexes. The result of the first procedure was flattened and symmetrical breast tissue bilaterally, essentially a correction of the gynecomastia. The herniated nipples were still present, however. Bilateral periareolar mastopexies were then performed with resulting reduction of the herniations. There were no complications with either procedure, and a good cosmetic result was achieved. A staged surgical approach was successful in correcting both conditions with an excellent aesthetic result and the advantage of decreased risk for nipple complications.

    Full Text Available OBJECTIVE: Evaluate the predictive value of the Lasègue sign on self-reported quality of life measures (HRQoL in patients who undergo microdiscectomy. METHODS: 95 patients with clinical and radiological diagnosis of LDH who underwent microdiscectomy were included. The patients were assessed by a neurological examination and answered validated instruments to assess pain, disability, quality of life, and mood disorder in the preoperative period, and 1, 6 and 12 months after surgery. RESULTS: Preoperative Lasègue sign was identified in 56.8% (n=54/95 of the cases. There was no difference between the groups in the preoperative period regarding HRQoL. At one year follow-up no statistically significant difference in HRQoL was observed in the Lasègue group. The discrimination capacity of the preoperative Lasègue sign to determinate variations in HRQoL outcomes one year postoperatively was low. CONCLUSION: Lasègue sign is not a good predictor of outcome after microdiscectomy for LDH.

    Full Text Available Lumbar stenosis is an increasingly common pathological condition that is becoming more frequent with increasing mean life expectancy, with high costs for society. It has many causes, among which degenerative, neoplastic and traumatic causes stand out. Most of the patients respond well to conservative therapy. Surgical treatment is reserved for patients who present symptoms after implementation of conservative measures. Here, a case of severe stenosis of the lumbar spine at several levels, in a female patient with pathological and surgical antecedents in the lumbar spine, is presented. The patient underwent two different decompression techniques within the same operation.

    Full Text Available Background: Avaialable minimal invasive arthro/endoscopic techniques are not compatible with 30 degree arthroscope which orthopedic surgeons uses in knee and shoulder arthroscopy. Minimally invasive “Arthrospine assisted percutaneous technique for lumbar discectomy” is an attempt to allow standard familiar microsurgical discectomy and decompression to be performed using 30° arthroscope used in knee and shoulder arthroscopy with conventional micro discectomy instruments. Materials and Methods: 150 patients suffering from lumbar disc herniations were operated between January 2004 and December 2012 by indiginously designed Arthrospine system and were evaluated retrospectively. In lumbar discectomy group, there were 85 males and 65 females aged between 18 and 72 years (mean, 38.4 years. The delay between onset of symptoms to surgery was between 3 months to 7 years. Levels operated upon included L1-L2 (n = 3, L2-L3 (n = 2, L3-L4 (n = 8, L4-L5 (n = 90, and L5-S1 (n = 47. Ninety patients had radiculopathy on right side and 60 on left side. There were 22 central, 88 paracentral, 12 contained, 3 extraforaminal, and 25 sequestrated herniations. Standard protocol of preoperative blood tests, x-ray LS Spine and pre operative MRI and pre anaesthetic evaluation for anaesthesia was done in all cases. Technique comprised localization of symptomatic level followed by percutaneous dilatation and insertion of a newly devised arthrospine system devise over a dilator through a 15 mm skin and fascial incision. Arthro/endoscopic discectomy was then carried out by 30° arthroscope and conventional disc surgery instruments. Results: Based on modified Macnab's criteria, of 150 patients operated for lumbar discectomy, 136 (90% patients had excellent to good, 12 (8% had fair, and 2 patients (1.3% had poor results. The complications observed were discitis in 3 patients (2%, dural tear in 4 patients (2.6%, and nerve root injury in 2 patients (1.3%. About 90% patients

    To assess the clinical and radiographic outcomes and complications of anterior lumbar interbody fusion (ALIF) versus transforaminal lumbar interbody fusion (TLIF). A systematic literature search was conducted from six electronic databases. The relative risk and weighted mean difference (WMD) were used as statistical summary effect sizes. Fusion rates (88.6% vs. 91.9%, P = 0.23) and clinical outcomes were comparable between ALIF and TLIF. ALIF was associated with restoration of disk height (WMD, 2.71 mm, P = 0.01), segmental lordosis (WMD, 2.35, P = 0.03), and whole lumbar lordosis (WMD, 6.33, P = 0.03). ALIF was also associated with longer hospitalization (WMD, 1.8 days, P = 0.01), lower dural injury (0.4% vs. 3.8%, P = 0.05) but higher blood vessel injury (2.6% vs. 0%, P = 0.04). ALIF and TLIF appear to have similar success and clinical outcomes, with different complication profiles. ALIF may be associated with superior restoration of disk height and lordosis, but requires further validation in future studies.

    To determine the results of discectomy surgery for lumbar disc herniation in military personnel and compare it with civilians. One-hundred and seventeen military patients (54 subjects as combat forces and 63 as office personnel) and 115 civilians, who underwent discectomy surgery were included. In a mean duration of 50.8 months, the ability to return to full duty and resolution of complaints were assessed and satisfaction was measured using a Visual Analog Scale. Inability to return to previous duty was significantly higher in military personnel compared to civilians (p = 0.002); and in combat forces compared to office personnel (p 0.05). Surgical intervention had relatively poor outcomes in military personnel, specifically in combat forces. Prevention of injury to back region should be considered in military training programs and in case of presence of disc herniation related symptoms, efforts should be made to save patients effective function by conservation and medical therapies.

    Low back pain is probably the second most common disease entity to upper respiratory infection in developed country. We were missing at least 50% of the pathologic conditions by using conventional diagnostic modalities in low back pain. They did tell us nothing or little about facet abnormalities, lateral recesses, vertebral canal and soft tissue surrounding lumbar spines. High resolutional CT has been the biggest turning point in the diagnosis and management of low back pain. CT make a contribution to reducing the morbidity and probably the cost of evaluating patients with low back pain, and to increasing diagnostic accuracy. We observed 100 cases of lumbar CT using TCT 80A scanner for the evaluation of low back pain during the period from Apr. 1985 to Sept. 1985 at Chung-Ang University Hospital. Lumbar CT scan reveals high-positive findings (98%) in low back pain patients. Common low back disorders in CT are disc bulging (53%), herniated nucleus pulposus (32%), degenerative arthritis in posterior facet joints (27%), spinal stenosis (20%) and postoperative spines (15%). Uncommon low back disorders in CT are compression fracture of vertebral bodies, spondylolysis or spondylolisthesis, tropism, transitional vertebra, Scheueman's disease, limbic fracture, transverse process or articular process fracture, sacroiliac joint subluxation, conjoined nerve root and meningocele.

    To assess the location and associated findings of fractures of the posterior lumbar vertebral ring apophysis as seen on MRI We retrospectively evaluated MR findings in 77 patients (86 lesions) with lumbar apophyseal ring fractures. Their age ranged from ten to 67 (mean 33-1) years. To confirm the presence of verterbral ring fractures, CT was performed in 29 patients (31 lesions) within two weeks of MR imaging. Open laminectomy was performed in ten patients, percutaneous automated nucleotomy in three, and LASER operation in four. The most common location of fractures was the superior margin of L5 (36 lesions 41.9%), next was superior margin of S1 (21 lesions, 24.4%). On CT, a bony fragment was seen in 28 patients (30 lesions); the positive predictive value of MR was 99.7%. Multiple lesions were seen in nine patients. Associated disc herniation and bulging were noted in 64 (74.4%) and 15 lesions (17.4%), respectively, and a high signal intensity rim aound the bony fragment on T1 weighted image was noted in 33 (38.4%). Other associated findings were spondylolysis in eight patients, retrolisthesis in five, and spondylolisthesis in three. Operative outcomes were variable. The results of open laminectomy were better than those of percutaneous automated laminectomy or LASER operation. In patients with lumbar apophyseal ring fractures, their exact location and associated findings could be evalvated by MRI, which was therefore useful in the planning of appropriate surgery.

    Anomalies in the frontal lobe can interfere with visual function by compression of the optic chiasm and nerve. The gyrus rectus is located at the anterior cranial fossa floor superior to the intracranial optic nerves and chiasm. Compression of these structures by the gyrus rectus is often caused by neoplastic or dysplastic growth in the area. We report a rare case of a herniated gyrus rectus impinged on the optic chiasm and nerve without a clear pathological cause for the herniation. Copyright © 2016 Elsevier B.V. All rights reserved.

    Seven measures at the three lowest lumbar interspaces were recorded from conventional radiographs of the lumbar spines of 160 consecutive patients with low back pain and sciatica admitted for myelography and possible surgery. Eighty-eight patients were operated upon for disc herniation, and of the conservatively-treated 72 patients, 18 had a pathologic and 54 a normal myelogram. The results were evaluated after one year using the occupational handicap scales of WHO. Correlations of radiographic measures to stature were moderate and to age small. After adjusting for stature and age, only the male interpedicular distances and the antero-posterior diameter of intervertebral foramen at L3 were greater than those of females. The males with a pathologic myelogram had smaller posterior disc height at L3 and a smaller interarticular distance at L3 and L4 than those with normal myelogram, likewise the midsagittal diameter at L3 and L4 in females. In all patients other measures besides posterior disc height were smaller than those for low back pain patients (p<0.001) or for cadavers (p<0.001). The only correlation between measures and clinical manifestations was between pedicular length at L3 and limited straight leg raising. Where the disc material had been extruded into the spinal canal, the interpedicular distance was significantly wider. Only anterior disc height at L3 revealed differences between good and poor outcome one year after surgery, as did the interarticular distance at S1 in patients with normal myelogram after conservative treatment.

    Three-dimensional (3-D) magnetic resonance (MR) images obtained from 10 patients with lumbar degenerative diseases were retrospectively reviewed to determine how far 3-D MR imaging is capable of demonstrating nerve roots. In 8 of the 10 patients, the area up to the dorsal root ganglion was visualized on 3-D MR images. Thus, it is capable of detecting a wide area of nerve roots, thereby allowing the determination of running of nerve root, and size and location of dorsal root ganglion. In delineating the area from the dural canal to root cyst, 3-D MR imaging was equal to conventional myelography. The former was superior to the latter in detecting the positional relation between the degenerative intervertebral disc and the nerve root, and herniation-compressed root cyst. In 3 of 9 patients who presented with root symptoms, disturbed nerve roots were of high signal on 3-D MR images. This may suggest that it has the potential for selectively detecting root nerves associated with clinical manifestations. (N.K.)

    The herniated nucleus pulposus (HNP) is a major cause of low back pain and sciatica. High resolution computed tomography is the most accurate diagnostic tool to define a HNP, because it provides a complete in vivo analysis of bony framework of lumbar spine as well as the supporting soft tissue structures and neural elements. But the discrepancy between neurologic findings and CT findings is often confusing. From May 1983 to August 1986, sixty patients with HNP who had both CT and surgical intervention at Pusan National University Hospital were analyzed. The feasibility of the neurologic examination on HNP and the effect of HNP on nerve root were evaluated on the basis of CT findings. The results were as follows : 1. Thirty-four cases (56.7%) of clinical impression were matched to CT findings in determining level of HNP and affected nerve root. 2. In evaluation of affected level, there was high trend to cause discrepancy between neurologic findings and CT findings in multiple disc involvement than in single involvement. 3. There was no correlation between degree of nerve root compression determined by CT and pattern of neurologic signs (motor weakness, sensory deficit, and reflex change)

    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.)

    We report the radiologic findings of herniation of Hoffa's fat pad through a defect in the lateral patellar retinaculum in young children who presented with painless masses visible by ultrasound (US) only with flexion of the knee. Six children, between the ages of 1-8 years, presented with an anterolateral knee mass that was not tender and was only seen and palpable with knee flexion. An US was performed in all patients, magnetic resonance imaging (MRI) in 2 patients and knee radiographs in 1 patient. US imaging displayed focal herniation of Hoffa's fat pad within the infrapatellar region through a defect of the lateral retinaculum, visible only during dynamic imaging when the knee was in flexion. MRI performed in knee extension did not demonstrate a mass; however, it revealed a focal defect in the lateral retinaculum in the region of the abnormality. Radiographs were normal. Focal herniation of Hoffa's fat pad is an uncommon cause of an anterolateral knee mass in young children. When a knee mass is only identified in flexion, focal fat herniation through a defect in the retinaculum should be suspected and a dynamic US should be performed. (orig.)

    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.

  16. Lumbar dorsal ramus syndrome.

    1980-11-15

    Low back pain, referred pain in the lower limbs, and spasm of the back, gluteal, and hamstring muscles are clinical features which can be induced in normal volunteers by stimulating structures which are innervated by the lumbar dorsal rami. Conversely, they can be relieved in certain patients by selective interruption of conduction along dorsal rami. These facts permit the definition of a lumbar dorsal ramus syndrome, which can be distinguished from the intervertebral disc syndrome and other forms of low back pain. The distinguishing feature is that, in lumbar dorsal ramus syndrome, all the clinical features are exclusively mediated by dorsal rami and do not arise from nerve-root compression. The pathophysiology, pathology, and treatment of this syndrome are described. Recognition of this syndrome, and its treatment with relatively minor procedures, can obviate the need for major surgery which might otherwise be undertaken.

    Technological advances have changed the indications for and the way in which lumbar puncture is done. Suspected CNS infection remains the most common indication for lumbar puncture, but new molecular techniques have broadened CSF analysis indications, such as the determination of neuronal autoantibodies in autoimmune encephalitis. New screening techniques have increased sensitvity for pathogen detection and can be used to identify pathogens that were previously unknown to cause CNS infections. Evidence suggests that potential treatments for neurodegenerative diseases, such as Alzheimer's disease, will rely on early detection of the disease with the use of CSF biomarkers. In addition to being used as a diagnostic tool, lumbar puncture can also be used to administer intrathecal treatments as shown by studies of antisense oligonucleotides in patients with spinal muscular atrophy. Lumbar puncture is generally a safe procedure but complications can occur, ranging from minor (eg, back pain) to potentially devastating (eg, cerebral herniation). Evidence that an atraumatic needle tip design reduces complications of lumbar puncture is compelling, and reinforces the need to change clinical practice. Copyright © 2018 Elsevier Ltd.

    Back pain attributable to lumbar disc herniation is a substantial cause of reduced workplace productivity. Disc herniation surgery is effective in reducing pain and improving function. However, few studies have examined the effects of surgery on worker productivity. We wished to determine the effect of disc herniation surgery on workers' earnings and missed workdays and how accounting for this effect influences the cost-effectiveness of surgery? Regression models were estimated using data from the National Health Interview Survey to assess the effects of lower back pain caused by disc herniation on earnings and missed workdays. The results were incorporated into Markov models to compare societal costs associated with surgical and nonsurgical treatments for privately insured, working patients. Clinical outcomes and utilities were based on results from the Spine Patient Outcomes Research Trial and additional clinical literature. We estimate average annual earnings of $47,619 with surgery and $45,694 with nonsurgical treatment. The increased earnings for patients receiving surgery as compared with nonsurgical treatment is equal to $1925 (95% CI, $1121-$2728). After surgery, we also estimate that workers receiving surgery miss, on average, 3 fewer days per year than if workers had received nonsurgical treatment (95% CI, 2.4-3.7 days). However, these fewer missed work days only partially offset the assumed 20 workdays missed to recover from surgery. More fully accounting for the effects of disc herniation surgery on productivity reduced the cost of surgery per quality-adjusted life year (QALY) from $52,416 to $35,146 using a 4-year time horizon and from $27,359 to $4186 using an 8-year time horizon. According to a sensitivity analysis, the 4-year cost per QALY varies between $27,921 and $49,787 depending on model assumptions. Increased worker earnings resulting from disc herniation surgery may offset the increased direct medical costs associated with surgery. After

    Magnetic resonance T2 mapping allows for the quantification of water and proteoglycan content within tissues and can be used to detect early cartilage abnormalities as well as to track the response to therapy. The goal of the present study was to use T2 mapping to quantify intervertebral disk water content according to the Pfirrmann classification. This study involved 60 subjects who underwent lumbar magnetic resonance imaging (a total of 300 lumbar disks). The degree of disk degeneration was assessed in the midsagittal section on T2-weighted images according to the Pfirrmann classification (grades I to V). Receiver operating characteristic (ROC) analysis was performed among grades to determine the cut-off values. In the nucleus pulposus, T2 values tended to decrease with increasing grade, and there was a significant difference in T2 values between each grade from grades I to IV. However, there was no significant difference in T2 values in the anterior or posterior annulus fibrosus. T2 values according to disk degeneration level classification were as follows: grade I (>116.8 ms), grade II (92.7-116.7 ms), grade III (72.1-92.6 ms), grade IV (<72.0 ms). T2 values decreased with increasing Pfirrmann classification grade in the nucleus pulposus, likely reflecting a decrease in proteoglycan and water content. Thus, T2 value-based measurements of intervertebral disk water content may be useful for future clinical research on degenerative disk diseases. (orig.)

  20. Oscillations of disks

    CERN Document Server

    Kato, Shoji

    2016-01-01

    This book presents the current state of research on disk oscillation theory, focusing on relativistic disks and tidally deformed disks. Since the launch of the Rossi X-ray Timing Explorer (RXTE) in 1996, many high-frequency quasiperiodic oscillations (HFQPOs) have been observed in X-ray binaries. Subsequently, similar quasi-periodic oscillations have been found in such relativistic objects as microquasars, ultra-luminous X-ray sources, and galactic nuclei. One of the most promising explanations of their origin is based on oscillations in relativistic disks, and a new field called discoseismology is currently developing. After reviewing observational aspects, the book presents the basic characteristics of disk oscillations, especially focusing on those in relativistic disks. Relativistic disks are essentially different from Newtonian disks in terms of several basic characteristics of their disk oscillations, including the radial distributions of epicyclic frequencies. In order to understand the basic processes...

    CT scan is peculiarly effective in the study of architectural pathologies of the column; it appears that a number of etiological factors of low back pain are involved and they are often related. Indeed, dis herniation, for instance, is frequently associated with facetal asymmetry, the first signs of arthroses and ligamentous calcification after treatment. The three vertebral axes must be evaluated, one discal and two facetal, the slightest defect in one of which can affect the two others. Moreover, in view of the complexity of the innervation, the entire lumbar column from L1 to L5 S1 must be investigated: it is not uncommonly that low sciatica is caused by a more cranial lumbar pathology. This systematic study promotes better understanding of the etiology of low back pain and suggests a stet judicious therapeutic attitude.

    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.

    2008-01-01

    Objective: To evaluate imaging appearances of herniation pit of the femoral neck. Methods: We retrospectively analyzed the X-ray, CT and MRI findings of 9 patients with herniation pit of the femoral neck. All nine patients were male with the age ranging from 21 to 73 years. They had pain in the hip from two months to two years duration. Results: The bilateral hips were affected in six patients, the right hips in the other 3 patients. Of the nine patients, X-ray plain films (2 cases), CT scanning(6 cases), and MR scanning (5 cases ) were performed. The size of the lesions ranged from 0.5 cm x 0.6 cm to 1.0 cm x 1.5 cm, located in the anterosuperior portion of the femoral neck (n=7) or anteroinferior portion (n=2). X-ray plain films showed an osteolytic lesion surrounded by a sclerotic rim. CT scanning showed the lesion just below the cortex of the femoral neck surrounded by a rim of sclerosis or associated with a small cortical break in two patients. MR scanning showed low signal intensity in five patients on T 1 WI and high signal intensity surrounded by a rim of low signal intensity (n=3) or low signal intensity (n=2) on T 2 WI, and high signal intensity on fat suppression MR image. A small joint effusion was observed in two cases on T 2 WI. Conclusion: The CT and MRI findings of herniation pit of the femoral neck are characteristic, it is useful in defining the diagnosis of the herniation pit of the femoral neck. (authors)

    The authors report radiological findings in 13 cases of avulsion of the posterior lumbar apophyseal ring. The lesion affected young adults in 10 cases and adolescents in 3 cases. The lesion involved the inferior endplate of L4 in 11, and of L5 in 2 patients. 6 patients presented with unilateral sciatica, 3 with bilateral sciatica, and 4 with low back pain. Acute spinal trauma was evident only in 2 adolescents. Radiological recognition of the lesion was possible on plain films in 9 cases. CT demonstrates association of avulsion of the posterior vertebral apophyseal ring and herniated disc in all cases. Avulsion of the posterior apophyseal ring has to be differentiated from posterior longitudinal ligament, annulus, or herniated disc calcifications, as well as from posterior degenerative ridge osteophytes. Controversy about physiopathology of the lesion remains: Weakness of the apophyseal ring during childhood and in patients with Scheuermann's disease may explain avulsion of the apophyseal ring in association with median disc herniation.

  9. Intrathecal ligaments and nerve root tension: possible sources of lumbar pain during spaceflight.

    2004-04-01

    Lumbar intrathecal ligaments have recently been demonstrated to randomly bind dorsal nerve roots to the dura within the lumbar vertebral column. Lengthening of the vertebral column and associated lumbar back pain experienced by astronauts is common in microgravity. This study was designed to investigate the relationship of lumbar intrathecal ligaments in spinal lengthening as a possible mechanism for back pain. A two-part study was designed using 36 vertebral columns from embalmed cadavers. There were 12 vertebral columns studied in mid-sagittal section to demonstrate the possible movement of the spinal cord during lengthening of the vertebral column. The remainder were assessed for the amount of tension placed on a dorsal nerve root by the lumbar intrathecal ligament during lengthening of the vertebral column. The spinal cord moves in a cephalic direction approximately 2.8 mm with 4 cm lengthening of the vertebral column. During lengthening, a loss of thoracic and lordotic curvature was noted with an increase in disk height. Tension was significantly increased on the dorsal nerve roots being tethered by the lumbar intrathecal ligaments in comparison to non-tethered nerve roots during lengthening of the vertebral column. A significant amount of tension is placed on dorsal nerve roots tethered by intrathecal ligaments within the lumbar spine during spinal lengthening. These ligaments randomly bind dorsal nerve roots in the lumbar spine and may be involved in the back pain experienced by astronauts in microgravity.

    1989-12-01

    Bertolotti's syndrome refers to the association of back pain with lumbosacral transitional vertebrae. Such vertebrae were observed in 140 of 2,000 adults with back pain over a 4-year period of study. Each patient had radiographic evaluation of the lumbar spine by plain films as well as a sectional imaging modality (magnetic resonance [MR] or computed tomography [CT]). The overall incidence of structural pathology (eg, spinal stenosis and disc protrusion) detected by CT or MR was not apparently higher in patients with transitional vertebrae, but the distribution of these lesions was significantly different. Disc bulge or herniation, when it occurred, was nearly nine times more common at the interspace immediately above the transitional vertebra than at any other level. Spinal stenosis and nerve root canal stenosis were more common at or near the interspace above the transitional vertebra than at any other level. Degenerative change at the articulation between the transverse process of the transitional vertebra and the pelvis was an uncommon occurrence; when seen there was no significant correlation with the reported side of pain. It is postulated that hypermobility and altered stresses become concentrated in the spine at the level immediately above a lumbar transitional vertebra. Accelerated disc and facet joint degeneration at this level may then result.

    Internal herniation is a rare cause of intestinal obstruction, especially in the emergency department. We report a child with acute abdomen resulting from transmesenteric internal herniation of the small bowel. Radiographic findings revealed gaseous distension of the bowel loops in the upper abdominal area with a paucity of gas in the lower abdomen. Operative finding showed gangrenous small bowel due to mesenteric defect with an internal herniation. The gangrenous bowel was resected and the patient was discharged with an uneventful outcome. We emphasize that early recognition of internal herniation warrants further evaluation and appropriate management. Copyright © 2012. Published by Elsevier B.V.

    Traumatic ruptures of the pericardium with cardiac herniation are infrequent, and their radiological pattern little familiar, so that they are often missed preoperatively. Few reports have emphasised the use of a CT scan as a tool for diagnosis and CT scan signs have not been well documented. We report on two cases of traumatic herniation of the heart for which a CT scan brought a major contribution for diagnosis. We describe the presence of an empty pericardial sac on CT slices which allowed us to diagnose the cardiac herniation. These observations demonstrate that CT scans can contribute to the diagnosis of pericardial rupture with cardiac herniation. (orig.)

    To determine frequency, imaging features and clinical significance of herniations of brain parenchyma into dural venous sinuses (DVS) and/or calvarium found on MRI. A total of 6160 brain MRI examinations containing at least one high-resolution T1- or T2-weighted sequence were retrospectively evaluated to determine the presence of incidental brain herniations into the DVS or calvarium. MRI sequences available for review were evaluated according to their capability to demonstrate these herniations. Patients' symptoms and clinical findings were recorded. Twenty-one (0.32 %) brain parenchyma herniations into the DVS (n = 18) or calvarium (n = 3) in 20 patients were detected. The most common locations of the herniations were the transverse sinuses (n = 13) and those involving inferior gyrus of the temporal lobe (n = 9). High-resolution T1- and T2-weighted sequences were equally useful in the detection of these brain herniations. According to clinical symptoms, brain herniations were considered to be incidental but headaches were present in nine patients. Brain herniations with surrounding cerebrospinal fluid (CSF) into the DVS and/or calvarium are incidental findings and not proven to be associated with any symptoms. Although rare, these herniations are more common than previously recognized and should not be confused with arachnoid granulations, clots or tumours. (orig.)

    Full Text Available Chordoma is a rare tumor arising from notochord remnants in the spine. It is slow-growing, which makes it difficult to diagnose and difficult to follow up after treatment. Typically, it occurs in the base of the skull and sacrococcygeal spine; it rarely occurs in other parts of the spine. CT-guided biopsy of a suspicious mass enabled diagnosis of lumbar spine chordoma.

    Many patients with lumbar disc surgery experience postoperative back and radicular pain, delaying hospital discharge and resumption of normal activity. Some surgeons have used intraoperative epidural corticosteroids and local anesthetics to decrease pain following surgery for a herniated lumbar disc. Controversies still exist regarding the benefits of these drugs. The present study was meant to compare the effects of the intraoperative administration of epidural methylprednisolone and bupivacaine with that of normal saline (placebo) in lumbar disc surgery for postoperative pain control. One hundred fifty patients with single level herniated nucleus pulposus (L4-L5 or L5-S1), which was refractory to 6 weeks of conservative management, were divided randomly in three groups. A standard hemipartial lamimectomy and discectomy was performed on all patients. At the end of the surgery, before the closure of fascia, 40 mg methylprednisoslone with 3 mL normal saline for group1, 2 mL bupivacaine 5% with 2mL normal saline for group 2 and 4 mL normal saline for group 3 were stilled on to the epidural and exposed nerve root. Postoperative back and radicular pain intensity was assessed by a visual analogue scale (VAS) before and at 24, 48, 72 and 96 hours after surgery. There was no significant difference in back and radicular pain intensity between the three groups. Introperative administration of epidural methylprednisolone or bupivacaine does not relieve postoperative back and radicular pain. (author)

  19. Curcumin alleviates lumbar radiculopathy by reducing neuroinflammation, oxidative stress and nociceptive factors

    Full Text Available Current non-surgical treatments for lumbar radiculopathy [e.g. epidural steroids and Tumour necrosis factor-α (TNF-α antagonists] are neither effective nor safe. As a non-toxic natural product, curcumin possesses an exceptional anti-inflammatory profile. We hypothesised that curcumin alleviates lumbar radiculopathy by attenuating neuroinflammation, oxidative stress and nociceptive factors. In a dorsal root ganglion (DRG culture, curcumin effectively inhibited TNF-α-induced neuroinflammation, in a dose-dependent manner, as shown by mRNA and protein expression of IL-6 and COX-2. Such effects might be mediated via protein kinase B (AKT and extracellular signal regulated kinase (ERK pathways. Also, a similar effect in combating TNF-α-induced neuroinflammation was observed in isolated primary neurons. In addition, curcumin protected neurons from TNF-α-triggered excessive reactive oxygen species (ROS production and cellular apoptosis and, accordingly, promoted mRNA expression of the anti-oxidative enzymes haem oxygenase-1, catalase and superoxide dismutase-2. Intriguingly, electronic von Frey test suggested that intraperitoneal injection of curcumin significantly abolished ipsilateral hyperalgesia secondary to disc herniation in mice, for up to 2 weeks post-surgery. Such in vivo pain alleviation could be attributed to the suppression, observed in DRG explant culture, of TNF-α-elicited neuropeptides, such as substance P and calcitonin gene-related peptide. Surprisingly, micro-computed tomography (μCT data suggested that curcumin treatment could promote disc height recovery following disc herniation. Alcian blue/picrosirius red staining confirmed that systemic curcumin administration promoted regeneration of extracellular matrix proteins, visualised by presence of abundant newly-formed collagen and proteoglycan content in herniated disc. Our study provided pre-clinical evidence for expediting this natural, non-toxic pleiotropic agent to become a

    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

    Retrospectively study.The purpose of this study was to compare the effects of intraoperative epidural steroids and single dose intravenous steroids following a percutaneous endoscopic lumbar discectomy (PELD).Inflammatory irritation of dorsal root ganglia or sensory nerve roots may cause postoperative pain. Epidural steroids have been applied after a lumbar discectomy for more than 20 years. Epidural steroid application after a PELD is easier to perform and safer because the operations are under observation of the scope.We retrospectively reviewed the medical records of patients with lumbar intervertebral disc herniation who had undergone transforaminal PELD at our department. There are 60 patients in epidural steroid group, intravenous steroid group, and control group, respectively. Visual analog scores (VAS) and the Oswestry Disability Index (ODI) were collected. Successful pain control is defined as 50% or more reduction in back and leg pain (VAS scores).VAS scores (back and leg) and ODI showed a significant decrease in all groups when comparing pre- and postoperatively. Epidural steroid group had a significant improvement in successful pain control compared with the control group at 2 weeks of follow-up. VAS scores (leg) in the epidural steroid group showed a significant decrease compared with the intravenous steroids group at 1, 3, and 7 days after the surgery, but this difference had no statistical significance at 1, 6, and 12 months of follow-up. All groups did not show a significant difference in ODI at 1, 6, and 12 months follow-up.Epidural application of steroid has a better effect on controlling the postoperative pain of PELD in the short term. The epidural application of steroid did not show a tendency to cause infection.

    The distributions and abundances of small organics in protoplanetary disks are potentially powerful probes of disk physics and chemistry. HNC is a common probe of dense interstellar regions and the target of this study. We use the Submillimeter Array (SMA) to observe HNC 3–2 toward the protoplanetary disks around the T Tauri star TW Hya and the Herbig Ae star HD 163296. HNC is detected toward both disks, constituting the first spatially resolved observations of HNC in disks. We also present SMA observations of HCN 3–2 and IRAM 30 m observations of HCN and HNC 1–0 toward HD 163296. The disk-averaged HNC/HCN emission ratio is 0.1–0.2 toward both disks. Toward TW Hya, the HNC emission is confined to a ring. The varying HNC abundance in the TW Hya disk demonstrates that HNC chemistry is strongly linked to the disk physical structure. In particular, the inner rim of the HNC ring can be explained by efficient destruction of HNC at elevated temperatures, similar to what is observed in the ISM. However, to realize the full potential of HNC as a disk tracer requires a combination of high SNR spatially resolved observations of HNC and HCN and disk-specific HNC chemical modeling

    Three-dimensional (3D) fast spin-echo sequence with variable flip-angle refocusing pulse allows retrospective alignments of magnetic resonance imaging (MRI) in any desired plane. To compare isotropic 3D T2-weighted (T2W) turbo spin-echo sequence (TSE-SPACE) with standard two-dimensional (2D) T2W TSE imaging for evaluating lumbar spine pathology at 3.0 T MRI. Forty-two patients who had spine surgery for disk herniation and had 3.0 T spine MRI were included in this study. In addition to standard 2D T2W TSE imaging, sagittal 3D T2W TSE-SPACE was obtained to produce multiplanar (MPR) images. Each set of MR images from 3D T2W TSE and 2D TSE-SPACE were independently scored for the degree of lumbar neural foraminal stenosis, central spinal stenosis, and nerve compression by two reviewers. These scores were compared with operative findings and the sensitivities were evaluated by McNemar test. Inter-observer agreements and the correlation with symptoms laterality were assessed with kappa statistics. The 3D T2W TSE and 2D TSE-SPACE had similar sensitivity in detecting foraminal stenosis (78.9% versus 78.9% in 32 foramen levels), spinal stenosis (100% versus 100% in 42 spinal levels), and nerve compression (92.9% versus 81.8% in 59 spinal nerves). The inter-observer agreements (κ = 0.849 vs. 0.451 for foraminal stenosis, κ = 0.809 vs. 0.503 for spinal stenosis, and κ = 0.681 vs. 0.429 for nerve compression) and symptoms correlation (κ = 0.449 vs. κ = 0.242) were better in 3D TSE-SPACE compared to 2D TSE. 3D TSE-SPACE with oblique coronal MPR images demonstrated better inter-observer agreements compared to 3D TSE-SPACE without oblique coronal MPR images (κ = 0.930 vs. κ = 0.681). Isotropic 3D T2W TSE-SPACE at 3.0 T was comparable to 2D T2W TSE for detecting foraminal stenosis, central spinal stenosis, and nerve compression with better inter-observer agreements and symptom correlation. © The Foundation Acta Radiologica 2014 Reprints and

    Purpose: To show the morphological changes in postoperative lumbar spine. Material and methods: We reviewed 128 Magnetic Resonance Imaging (MRI) studies of lumbar spine. All patients complained of low back pain and had a previous lumbar surgery (1 month to 8 years). All the examinations include axial and sagittal Gadopentate-dimeglumine enhanced T1 weighted imaging. Results: Only 7,8% have the normal appearance of the postoperative lumbar spine. Epidural scar was found in 69% of examinations; of this group, 72% showed radicular involvement, and 28% had no radicular involvement. Recurrent disc herniation was found in 14,8% of exams, using gadopentate-dimeglumine to assist the differentiation from epidural fibrosis; infections like spondylodiscitis and abscess in 12,5%. Other findings included arachnoiditis, pseudomeningoceles and seromas. Conclusions: MRI is a useful method to study the postoperative lumbar spine, specially when enhanced with gadopentate-dimeglumine. Enhanced images can differentiate two of the major complication like epidural fibrosis, and recurrent disc herniation. Spondylodiscitis are important and frequent too. Although the findings of complications in our series in the postoperative lumbar spine represent 92,18 %, these not always explain the symptomatology. Therefore, the interrelation is important with the surgeon to determine which abnormalities are clinically significant.

    We studied to provide precise correlations between the intensity of MRI signals and the degenerative changes of the nucleus pulposes of the L4/5 intervertebral disk herniations. 23 cases with the L4/5 intervertebral disk herniations having surgical treatment were examined using Magnetom H 15 (1.5 tesla) with surface coil. The images were obtained with T2 images (long TR (1000{approx}1600 msec), TE (60{approx}90 msec)). The intensity was measured using FUJI densitometer FD 101 at the lumber vertebral body and the intervertebral disk. We calculated the L4/5 intervertebral disk degeneration ratio (determined by comparing the modified L4/5 MR signal intensity with the modified L2/3 MR signal itensity). Histological changes were examined in the cellular components of the nucleus pulposus (such as the number of the nucleus cells, nucleus cell nesting and HE stainability of the nucleus cell) and the matrics substance (such as fibrillation, hyaline degeneration and granular degeneration). Histochemical studies were performed using Scott's Method (AB-0.4 M MgCl{sub 2} Alcinophilia, AB-09 M, MgCl{sub 2} Alcinophilia) to investigate glycosaminoglycans of the nucleus pulposus. We compared the histological and histochemical changes with the MR L4/5 intervetebral disk degeneration ratio. The decreasing MRI signal intensity of the nucleous pulposus was (1) corresponded to the pathological changes such as the increasing number of the cell nesting, fibrillation and hyaline degeneration of the nucleus polposus. (2) corresponded to the decrease in the total glycosaminoglycans of the nucleus pulposus. (3) corresponded to the early stage of degeneration of the nucleus polposus, but in aging when all levels of intervertebral disk degeneration appeared, we could not know the degree of the disk degeneration from the signal intensity of MRI.

    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.

    Muscle herniations are rare and most reported cases involve muscles of the lower leg. We use a case of muscle herniation involving the semimembranosus muscle, presenting as a painful mass in an adolescent male after an unspecified American football injury, to highlight a simple concept of muscle biomechanics as it pertains to muscle hernia(s): decreased traction upon muscle fibers can increase conspicuity of muscle herniation(s) - this allows a better understanding of the apt provocative maneuvers to employ, during dynamic ultrasound or magnetic resonance imaging, in order to maximize diagnostic yield and, thereby, limit patient morbidity related to any muscle herniation. Our patient subsequently underwent successful decompressive fasciotomy and has since returned to his normal daily activities. (orig.)

    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.

This circumplanetary disk is important to understand, since it both regulates the late gas accretion and forms the birthplace of future satellites of the planet.Weve yet to detect a circumplanetary disk thus far, because the resolution needed to spot one has been out of reach. Now, however, were entering an era where the disk and its kinematics may be observable with high-powered telescopes (like the Atacama Large Millimeter Array).To prepare for such observations, we need models that predict the basic characteristics of these disks like the mass, temperature, and kinematic properties. Now a researcher at the ETH Zrich Institute for Astronomy in Switzerland, Judit Szulgyi, has worked toward this goal.Simulating CoolingSzulgyi performs a series of 3D global radiative hydrodynamic simulations of 1, 3, 5, and 10 Jupiter-mass (MJ) giant planets and their surrounding circumplanetary disks, embedded within the larger circumstellar disk around the central star.Density (left column), temperature (center), and normalized angular momentum (right) for a 1 MJ planet over temperatures cooling from 10,000 K (top) to 1,000 K (bottom). At high temperatures, a spherical circumplanetary envelope surrounds the planet, but as the planet cools, the envelope transitions around 64,000 K to a flattened disk.

    Objectives: The purpose of this study is to determine if a pre-existing lumbar diagnosis such as spondylosis, a herniated lumbar disc, or spondylolysis affects a football player’s draft status or his performance and longevity in the NFL. Methods: The written medical evaluations and imaging reports of prospective professional American football athletes from 2003-2011 from one NFL franchise during the NFL combine (annual college football player evaluation prior to the NFL draft) were compiled and evaluated. All players were evaluated for a pre-existing lumbar diagnosis which were compiled from previous injury/medical records including radiographic imaging reports. Those players with a lumbar spine diagnosis and with appropriate radiograph, MRI and CT imaging were included in this study. These athletes were then matched by age, position, year, and round drafted to control draftees without a lumbar spine diagnosis. Career statistics were compiled including length of play and number of games started. Additionally, a previously established “Performance Score” was calculated for all players excluding offensive linemen. The continuous variables of each cohort were compared using a two-sided (tailed) Student’s t-test for normally distributed data. A chi-squared analysis was performed to analyze the categorical data. Statistical significance was accepted with a p < 0.05. Results: Out of a total of 2,965 athletes evaluated from the NFL combine, 414 players were identified with a pre-existing lumbar spine diagnosis. Athletes who attended the NFL combine without a lumbar spine diagnosis were significantly more likely to be drafted than those with one (74% vs. 61% respectively, p < 0.01). There was no difference between the investigational and control group with regard to round drafted, age, year drafted, or position. Overall, athletes with a lumbar spine injury compared to the control group had no difference in the number of years played (4.0 vs. 4.3 years, respectively

    Spinal angiolipomas are fairly infrequent benign tumours that are usually located in the epidural space of the thoracic column and represent 0.14% to 1.3% of all spinal tumours. Lumbar angiolipomas are extremely rare, representing only 9.6% of all spinal extradural angiolipomas. We report the case of a woman who complained of a lumbar pain of several months duration with no neurological focality and that had intensified in the last three days without her having had any injury or made a physical effort. The MR revealed an extradural mass L1-L2, on the posterior face of the medulla, decreasing the anteroposterior diameter of the canal. The patient symptoms improved after surgery. Total extirpation of the lesion is possible in most cases, and the prognosis is excellent even if the lesion is infiltrative. For this reason, excessively aggressive surgery is not necessary to obtain complete resection. Copyright © 2016 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

    Round, well-demarcated, symmetrical low densities in a bilateral thalamus in a case of descending transtentorial herniation due secondarily to acute traumatic left subdural hematoma are reported. An 8-year-old boy, on whom emergency surgery was refused by his parents, showed a marked shift due to the hematoma on admission; this was followed by a low density in the left PCA territory and round, equivocal hypodensities in the anterior thalamus 44 hours post-trauma. The equivocal hypodensities became definite, well-demarcated, round low densities situated symmetrically in the anterior thalamus on the 39th day post-trauma. Akinetic mutism was noted at this time. The symmetrical low densities and the PCA-territory low density persisted as late as the 39th day post-trauma, suggesting infarcts. The downward stretch of the bilateral thalamoperforators, which was effected by a narrowing of the interpeduncular fossa with an approximation of the bilateral perforators, plus a downward shift of the PCA due to descending transtentorial herniation, was assumed to be the mechanism involved.

    Injury to the diaphragm following blunt or penetrating thoracoabdominal trauma is not uncommon. Recognition of this important complication of trauma continues to be a challenge because of the lack of specific clinical and plain radiographic features, the frequent presence of other serious injuries and the potential for delayed presentation. Delayed diaphragmatic herniation often presents with catastrophic bowel obstruction or strangulation. Early recognition of diaphragmatic injury is required to avoid this potentially lethal complication. The case of a 35-year-old man with a history of a knife wound to the left flank 15 years previously, who presented with unexplained acute hypoxemic respiratory failure and a unilateral exudative pleural effusion that was refractory to tube thoracostomy drainage, is reported. After admission to hospital, he developed gross dilation of his colon; emergency laparotomy revealed an incarcerated colonic herniation into the left hemithorax. Interesting clinical features of this patient's case included the patient's hobby of weightlifting, a persistently deviated mediastinum despite drainage of the pleural effusion and deceptive pleural fluid biochemical indices.

    Idiopathic spinal cord herniation (ISCH) is an uncommon condition located predominantly in the thoracic spine and often associated with a remote history of a major traumatic injury. ISCH has an incompletely described presentation and unknown etiology. There is no consensus on the treatment algorithm and surgical technique, and there are few data on clinical outcomes. In this case series and technical report, we describe the atypical myelopathy presentation, remote history of traumatic injury, radiographic progression, treatment, and outcomes of 5 patients treated at Washington University for symptomatic ISCH. A video showing surgical repair is presented. In contrast to classic compressive myelopathy symptomatology, ISCH patients presented with an atypical myelopathy, characterized by asymmetric motor and sensory deficits and early-onset urinary incontinence. Clinical deterioration correlated with progressive spinal cord displacement and herniation observed on yearly spinal imaging in a patient imaged serially because of multiple sclerosis. Finally, compared with compressive myelopathy in the thoracic spine, surgical treatment of ISCH led to rapid improvement despite a long duration of symptoms. Symptomatic ISCH presents with atypical myelopathy and slow temporal progression and can be successfully managed with surgical repair.

    Lewis SE, Fowler NE. Changes in intervertebral disk dimensions after a loading task and the relationship with stature change measurements. To test the hypothesis that there would be a linear relationship between overall stature change determined by stadiometry and markers of lumbar disk height loss determined from magnetic resonance imaging (MRI). The short-term loading response of the lumbar spine was evaluated with both stadiometry and MRI, using a within-subject repeated-measures design. Measures were obtained both before and after 15 minutes of walking wearing a weighted vest (20% of body mass). Stature loss measured on the stadiometer was compared with change in lumbar spine length assessed from the MRI images. A university laboratory. Participants (N=13; mean age +/- SD, 28.5+/-5.2y; mean height +/- SD, 1.76+/-0.10m; mean body mass +/- SD, 76.6+/-14.9kg) were invited to take part in the investigation. The group was mixed (9 men, 4 women) and comprised people with no history of low back pain. Not applicable. Lumbar spine length assessed via MRI and stature change measured via stadiometry. A significant height loss was observed over the complete lumbar spine (Pstature loss (r=.61). The results were supportive of the use of stadiometry as an indirect measure of changes in intervertebral disk height.

    A major sequelae of lumbar fusion is acceleration of adjacent-level degeneration due to decreased lumbar lordosis. We evaluated the effectiveness of 4 common fusion techniques in restoring lordosis: instrumented posterolateral fusion, translumbar interbody fusion, anteroposterior fusion with posterior instrumentation, and anterior interbody fusion with lordotic threaded (LT) cages (Medtronic Sofamor Danek, Memphis, Tennessee). Radiographs were measured preoperatively, immediately postoperatively, and a minimum of 6 months postoperatively. Parameters measured included anterior and posterior disk space height, lumbar lordosis from L3 to S1, and surgical level lordosis.No significant difference in demographics existed among the 4 groups. All preoperative parameters were similar among the 4 groups. Lumbar lordosis at final follow-up showed no difference between the anteroposterior fusion with posterior instrumentation, translumbar interbody fusion, and LT cage groups, although the posterolateral fusion group showed a significant loss of lordosis (-10°) (Plordosis and showed maintenance of anterior and posterior disk space height postoperatively compared with the other groups. Instrumented posterolateral fusion produces a greater loss of lordosis compared with anteroposterior fusion with posterior instrumentation, translumbar interbody fusion, and LT cages. Maintenance of lordosis and anterior and posterior disk space height is significantly better with anterior interbody fusion with LT cages. Copyright 2011, SLACK Incorporated.

    Spondylolysis is a direct precursor of spondylolisthesis and can lead to crippling back pain. Of 1,743 patients surveyed, including 936 who were asymptomatic and 807 with back pain, 165 (including 91 who were asymptomatic and 74 with back pain) had spondylolysis, which was seen only on oblique lumbar views in 20% of cases. Because of the high false-negative rate of AP and lateral views, oblique views are essential in children and young adults. As spondylolysis is rare above L3, radiographs can be limited to L3-S1. Significantly less spondylolysis was seen in persons older than 30 with back pain usually caused by disk degeneration.

    Objective: To discuss the therapeutic benefit of fluoroscopically-guided lumbar transforaminal epidural steroid injections (TFESI) in treating patients with sciatica due to a herniated nucleus pulposus. Methods: From October 2004 to November 2007, fluoroscopically-guided lumbar TFESI as performed in 79 patients (41 males and 38 females with a mean age of 45.75 years,ranged from 20 to 70 years) with sciatica due to a herniated nucleus pulposus. Patients had a symptomatic course of disease from 8 weeks to 22 years and showed no response to conservative treatment. The diagnosis was confirmed by computed tomography or magnetic resonance imaging. TFESI was performed at patient's request. Additional injections, up to 3 times, were given with an interval of 7 or 10 days. The injection medicine consisted of 25 mg of prednisolone acetate and (9-14) ml of 0.5% lidocaine. Patients were evaluated by an independent observer and received questionnaires before the initial injection and at 6,12 months after TFESI. Questionnaires included an eleven points visual analog scale (VAS) and a five points patient satisfaction scale. A successful outcome required a patient satisfaction scale score of 3 (very good) or 4(excellent) and a reduction on the VAS score of 2 or more points after TFESI. Pain relief was classified as 'excellent' when the pain was completely resolved or diminished by 5 points or more, as 'good' when a diminution of pain was 2 points or more, as 'fair' and 'poor' when a diminution of pain was 1 point or less, or even an increase in pain. Results: Twenty-nine patients received single injection, 22 patients received two, 15 patients received three and 13 patients received four times of injection, with a mean of 1.96 times per patient. The mean VAS scores were 6.5(ranged 3.5-9.5) before and 3.8(ranged 0-9.5) 6 months after the procedure. Pain relief was graded as excellent in 35 patients (44.3%), good in 26 patients(32.9%), fair in 10 patients(12.7%), and poor in 8

    A retrospective comparative radiographic review. To evaluate the radiographic changes brought about by lordotic and nonlordotic cages on segmental and regional lumbar sagittal alignment and disk height in lateral lumbar interbody fusion (LLIF). The effects of cage design on operative level segmental lordosis in posterior interbody fusion procedures have been reported. However, there are no studies comparing the effect of sagittal implant geometry in LLIF. This is a comparative radiographic analysis of consecutive LLIF procedures performed with use of lordotic and nonlordotic interbody cages. Forty patients (61 levels) underwent LLIF. Average age was 57 years (range, 30-83 y). Ten-degree lordotic PEEK cages were used at 31 lumbar interbody levels, and nonlordotic cages were used at 30 levels. The following parameters were measured on preoperative and postoperative radiographs: segmental lordosis; anterior and posterior disk heights at operative level; segmental lordosis at supra-level and subjacent level; and overall lumbar (L1-S1) lordosis. Measurement changes for each cage group were compared using paired t test analysis. The use of lordotic cages in LLIF resulted in a significant increase in lordosis at operative levels (2.8 degrees; P=0.01), whereas nonlordotic cages did not (0.6 degrees; P=0.71) when compared with preoperative segmental lordosis. Anterior and posterior disk heights were significantly increased in both groups (Plordosis (lordotic P=0.86 vs. nonlordotic P=0.25). Lordotic cages provided significant increase in operative level segmental lordosis compared with nonlordotic cages although overall lumbar lordosis remained unchanged. Anterior and posterior disk heights were significantly increased by both cages, providing basis for indirect spinal decompression.
