    This is a rare case of giant lumbar pseudomeningocele with intra-abdominal extension in patient with neurofibromatosis type 1 (NF1). The patient's clinical course is retrospectively reviewed. A 34-year-old female affected by NF1 was referred to our institution for persistent low back pain and MRI diagnosis of pseudomeningocele located at L3 level with paravertebral extension. From the first surgical procedure by a posterior approach until the relapse of the pseudomeningocele documented by MRI, the patient underwent two subsequent posterior surgical procedures to repair the dural sac defect with fat graft and fibrin glue. One month after the third operation, the abdominal MRI showed a giant intra-abdominal pseudomeningocele causing compression of visceral structures. The patient was asymptomatic. The pseudomeningocele was treated with an anterior abdominal approach and the use of the acellular dermal matrix (ADM) sutured directly on the dural defect on the anterolateral wall of the spinal canal. After six months of follow-up the MRI showed no relapse of the pseudomeningocele. Our case highlights the possible use of ADM as an effective and safe alternative to the traditional fat graft to repair challenging and large dural defects. PMID:28250774

    Defective collagen biosynthesis in Marfan syndrome predisposes to dural defects such as dural ectasia, meningocele, and pseudomeningocele; thus, an increased index of suspicion for these conditions should be present in the clinical setting of Marfan syndrome. The authors describe a young woman with Marfan syndrome who was being treated with anticoagulants for a prosthetic heart valve and who presented with a spontaneous retroperitoneal hemorrhage requiring surgical evacuation. No CSF leak was encountered at surgery, but she developed progressively more severe positional headaches over the following year. She then experienced the sudden onset of acute urinary obstruction, at which time CT revealed a 17 × 15 × 13-cm presacral pseudomeningocele communicating with the thecal sac through a sacral bone defect. An anterior surgical approach was used for drainage of the pseudomeningocele as well as for primary closure of the dural defect with a bovine pericardial patch and autologous subcutaneous fat graft. After a short period of lumbar subarachnoid drainage of the CSF, the patient was able to resume normal activity without recurrent symptoms. To the authors' knowledge, such a pseudomeningocele in a patient with Marfan syndrome has been reported only twice, and this case features the largest pseudomeningocele to date. They also review the pertinent literature regarding presentation, diagnosis, and management of these lesions.

    Pseudomeningocele is an uncommon but well-known complication of lumbar spine operations. Although it is mostly asymptomatic and managed conservatively in most cases, it is claimed as a causative factor of failed back surgery syndrome and requires surgery in some cases. Usually, its diagnosis is confidently done with imaging modalities such as magnetic resonance imaging, computed tomography and myelography. In this report, we describe a case of pseudomeningocele that communicated with a facet joint. The diagnostic approach for this unusual lesion and its probable causes are discussed. (orig.)

    Pseudomeningocele arises after spinal fracture and nerve root avulsion or after complications of spine surgery. However, traumatic pseudomeningocele with spina bifida occulta is rare. In this report, a traumatic pseudomeningocele in a patient with spina bifida occulta that required surgical treatment is documented. This 37-year-old man presented to the authors' hospital with headache and a fluctuant mass in the center of his buttocks. A CT scan with myelography and MR imaging of the sacral region revealed a large subcutaneous area of fluid retention communicating with the intradural space through a defect of the S-2 lamina. Because 3 months of conservative treatment was unsuccessful, a free fat graft was placed with fibrin glue to seal the closure of the defect, followed by 1 week of CSF drainage. This is the first report on traumatic pseudomeningocele with spina bifida occulta successfully treated in this manner.

  6. Early Identification of Traumatic Durotomy Associated with Atlantooccipital Dislocation May Prevent Retropharyngeal Pseudomeningocele Development

    Full Text Available Atlantooccipital dislocation can be complicated by a traumatic durotomy that may lead to the rare development of a retropharyngeal pseudomeningocele. To our knowledge this has been reported only five times previously. We present the case of a 60-year-old man involved in a motor vehicle accident who suffered an atlantooccipital dislocation and C5-C6 three-column injury. A unique MRI image of a defect in the ventral dura posterior to C2 was appreciated. He underwent occiput to T2 internal fixation and arthrodesis. During surgery, CSF egress was seen caudal to the right C2 nerve root. A DuraMatrix onlay patch reinforced with DuraSeal was placed to stop the CSF leak. A lumbar subarachnoid drain was also placed. The patient made a satisfactory recovery with residual mild weakness of his right upper extremity. In this report, we demonstrate that careful MRI review can reveal a ventral durotomy in a traumatic atlantooccipital dislocation and, if discovered, effective treatment including a lumbar subarachnoid drain for CSF diversion may prevent progression to a retropharyngeal pseudomeningocele. The literature on this rare presentation and associated durotomy is provided.

    Inferior vena cava (IVC) filters are widely used to decrease the risk of pulmonary embolism in patients with contraindications to anticoagulation. Complications include local hematoma, access site deep venous thrombosis (DVT), filter migration and embolization, leg penetration through the IVC wall, IVC occlusion, and filter fracture with embolization. Other rare complications include leg penetration into adjacent organs including duodenum and ureter. Lumbar artery pseudoaneurysms are rare and may be spontaneous, iatrogenic, or traumatic. To date, there have been 3 case reports of lumbar artery pseudoaneurysms caused by IVC filters. We present an additional case of a lumbar artery pseudoaneurysm caused by a Gunther Tulip IVC filter treated successfully with selective embolization.

    Recently, we observed a case of lumbar artery injury after trauma, which was treated by endovascular embolization. A 67-year-old woman who was injured in a traffic accident was brought to the emergency room. She was conscious and her hemodynamic condition was stable, but she had paraplegia below L1 dermatome. Contrast-enhanced computed tomography scan of abdomen and pelvis revealed fracture dislocation of L3/4 along with retroperitoneal hematomas. However, there was no evidence of traumatic injury in both thoracic and abdominal cavity. At that time, her blood pressure suddenly decreased to 60/40 mmHg and her mental status deteriorated. Also, her hemoglobin level was 5.4 g/dl. While her hemodynamic condition stabilized with massive fluid resuscitation including blood transfusion, an angiography was immediately performed to look for and embolize site of retroperitoneal hemorrhage. On the angiographic images, there was an active extravasation from ruptured left 3rd lumbar artery, and we performed complete embolization with GELFOAM and coil. Lumbar artery injury after trauma is rare and endovascular treatment is useful in case of hemodynamic instability.

    A patient is presented in whom a focal reduction in marrow activity in the lumbar spine on both leucocyte and nanocolloid marrow scintigraphy was subsequently shown to be due to fatty infiltration of marrow in association with disc degeneration. Degenerative disease in the lumbar spine has not been previously described as a cause of abnormal bone marrow distribution by such means and needs to be distinguished from a more serious pathology, such as malignant infiltration and vertebral infection, which it may mimic. In a retrospective review of 33 nanocolloid bone marrow and 117 leucocyte scintigrams, 8 showed a degree of reduced marrow activity in the lumbar spine consistent with that caused by degenerative changes.

    Intracranial hypotension is a rare condition caused by spontaneous or iatrogenic CSF leaks that alter normal CSF dynamics. Symptoms range from mild headaches to transtentorial herniation, coma, and death. Duret hemorrhages have been reported to occur in some patients with this condition and are traditionally believed to be associated with a poor neurological outcome. A 73-year-old man with a remote history of spinal fusion presented with syncope and was found to have small subdural hematomas on head CT studies. He was managed nonoperatively and discharged with a Glasgow Coma Scale score of 15, only to return 3 days later with obtundation, fixed downward gaze, anisocoria, and absent cranial nerve reflexes. A CT scan showed Duret hemorrhages and subtle enlargement of the subdural hematomas, though the hematomas remained too small to account for his poor clinical condition. Magnetic resonance imaging of the spine revealed a large lumbar pseudomeningocele in the area of prior fusion. His condition dramatically improved when he was placed in the Trendelenburg position and underwent repair of the pseudomeningocele. He was kept flat for 7 days and was ultimately discharged in good condition. On long-term follow-up, his only identifiable deficit was diplopia due to an internuclear ophthalmoplegia. Intracranial hypotension is a rare condition that can cause profound morbidity, including tonsillar herniation and brainstem hemorrhage. With proper identification and treatment of the CSF leak, patients can make functional recoveries.

    Cervical nerve root avulsion is a well-documented result of motor vehicle collision (MVC), especially when occurring at high velocities. These avulsions are commonly traction injuries of nerve roots that may be accompanied by a tear in the meninges through the vertebral foramina with associated collections of cerebrospinal fluid (CSF), thereby resulting in a pseudomeningocele. We present a case of a 19-year-old male who experienced an MVC and was brought to the emergency department (ED) with right arm paralysis and other injuries. A neurological examination demonstrated intact sensation but 0/5 muscle strength in the right upper extremity. A magnetic resonance imaging (MRI) of the spinal cord demonstrated massive epidural hematomas extending the length of the cervical spine caudally from C2. An MRI of the right brachial plexus showed C3-C7 anterior horn cell edema and associated traumatic nerve root avulsion with pseudomeningoceles on the right from C5-C8. The development of spinal cord hematoma with these injuries has rarely been documented in the literature and the multiple level avulsion described here with extensive hematoma is a rare clinical presentation. A literature review was conducted to determine the diagnostic requirements, treatment strategies, and complications of such an injury. Our patient received conservative treatment of the right brachial plexus injury and was transferred to an inpatient rehabilitation facility 13 days later.  PMID:28352498

    A case report is presented of a patient with an anterosuperior osteophytic bone bridge of the sacroiliac joint causing lumbar back pain. After prolonged physiotherapy, the bone bridge was excised, with complete resolution of the symptoms. Excision should only be considered in cases of symptomatic sacroiliac joint pain that does not respond to rehabilitation programmes and conservative treatment.

    Brucellosis is an infectious disease spread by consumption of non-pasteurized milk products or through contact with infected animals. Spinal involvement is one of the most important complications and the lumbar area is the most frequently affected site. Among the neurological consequences, nerve root compression can be a result of epidural abscess, granuloma or discitis secondary to vertebral body involvement. In this case report we present a 50-year-old male patient with brucellar discitis without spondylitis which caused lumbar disc herniation. We want to emphasize that discitis should also be considered in differential diagnosis of nerve root compression in suspected cases.

    The authors report the case of a 31-year-old man who developed neck pain and headache 2 months after the uncomplicated resection of a cervical schwannoma. MR imaging revealed infratentorial subdural fluid collections and obstructive hydrocephalus associated with cervical pseudomeningocele. The clinical symptoms, subdural fluid collections, and ventricular dilation resolved after surgical correction of the pseudomeningocele. This report emphasizes that hydrocephalus may be related to disorders of cerebrospinal fluid flow dynamics induced by cervical pseudomeningocele. In these rare cases, both the hydrocephalus and the symptoms are resolved by the simple correction of the pseudomeningocele.

    [Purpose] The purpose of this study was to analyze changes in the electromyographic activities of the lumbar erector spinae caused by inversion traction in order to verify the relaxation effect. [Subjects and Methods] The subjects included 60 healthy male adults who were equally and randomly assigned to a 30-30° group, a 30-60° group, and a 60-60° group. Inversion traction was performed for six minutes, and the electromyographic activities of the lumbar erector spinae (L2, L4) were measured before and after inversion traction. [Results] The root mean square values at the L2 and L4 levels on both sides were statistically significantly higher after inversion traction compared with before inversion traction. Before inversion traction, the root mean square values at the L2 and L4 levels on both sides in the 30-60° group and 60-60° group were significantly higher than those in the 30-30° group, while the root mean square values at the L2 and L4 levels on both sides showed no significant differences between the groups before inversion traction. [Conclusion] The findings of this study indicated that IT is more likely to elicits an increase in muscle tension and prevent relaxation of the lumbar erector spinae.

    2015-12-01

    Full Text Available The purpose of the study is to analyze and systematize main causes of secondary spine deformations forming in patients who had operations due to thoracic and lumbar spine damages. Material and Methods. The analysis of poor surgical results of 155 patients previously operated due to various thoracic and lumbar spine damages has been conducted. All patients had complications associated with secondary spinal column deformations at various time after the intervention. Standard investigation included the analysis of patients' complaints, their previous history, somatic, neurological and orthopedic status. Results. The intensity of spinal column deformation was defined due to the character and level of primary trauma structurally characterized predominantly by unstable damages. However as it has been found in this research the main cause of this complicated pathology lied in the number of tactical and technical pitfalls of primary surgical treatment. Conclusion. Surgical operations due to secondary post-traumatic deformations in most cases are laborious and are accompanied by significant surgical trauma therefore systematization and analysis of the main causes of poor results of primary spine surgery may contribute to the preventive treatment of this type of pathology.

  1. THE ROLE OF LIGAMENTUM FLAVUM CALCIFICATION AT LUMBAR SPINE CAUSING CAUDA EQUINA SYNDROME AND LUMBAR RADICULOPATHY: CASE REPORT

    2013-10-01

    Full Text Available ABSTRACT: The focal calcification or ossification of ligamentum flavum is a rare cau se of thoracic myelopathy and most often occurs among individuals of Japanese descent. It is rare in other ethnic groups and in individuals below the age of 50 year. It is most often described at the lower thoracic level, being uncommon in the lumbar regio n and rare in the cervical region. Here, we present the case of a 40 - year - old Indian female patient who sought medical attention with a six month history of paraesthesia of the lower limbs and progressive difficulty in walking. The clinical profile, togeth er with computed tomography and magnetic resonance imaging of the spine, led to a diagnosis of compressive lumbar myelopathy due to ossification of the ligamentum flavum of lumbar spine. The patient underwent laminectomy and dissection of some of the affec ted ligamentum flavum. After three months of clinical follow - up, the patient had progressed favorably , having no sensory complaints and again becoming ambulatory

    Lumbar spine synovial cysts are becoming more frequent, and they are generally associated with degenerative lumbar spinal disease. They are common in lower lumbar lesions but rare in upper lumbar lesions. Several cases of hemorrhage into lower lumbar juxtafacet cysts after trauma or anticoagulation therapy have been reported in the literature. This article describes a case of subacute cauda equina syndrome resulting from spontaneous hemorrhage into an upper lumbar synovial cyst. A 65-year-old man presented with a 3-month history of intermittent bilateral lumbar pain. One week before, he experienced a sudden exacerbation of lumbar pain and began falling frequently; he also reported weakness and tingling in his lower limbs. A hematic collection associated with a large juxtafacet cyst at L2-L3 was suspected on magnetic resonance imaging. He underwent surgical decompression, and the cyst was resected. Microscopic examination was consistent with the diagnosis of a synovial cyst. Two days postoperatively, he was walking independently. Although several descriptions exist of hemorrhagic lumbar juxtafacet cysts after trauma or anticoagulant therapy, to the authors' knowledge, this is the first documented case of hemorrhage in an upper lumbar synovial cyst with no previous traumatic event or medication use. Magnetic resonance imaging was essential in making the preoperative diagnosis. Surgical removal of the cyst was an effective treatment. Copyright 2012, SLACK Incorporated.

  3. Four-Rod Stabilization of Severely Destabilized Lumbar Spine Caused by Metastatic Tumor

    2013-01-01

    Full Text Available We report a case of a 67-year-old female with severely destabilized lumbar spine caused by metastatic malignant tumor. The primary lesion was a thyroid follicular adenocarcinoma. Complete destruction of the L3, L4, and L5 vertebrae had resulted in severe instability, which left the patient with severe back pain and bed-ridden. Since the vertebrae were so severely damaged at 3 levels, 4 rods were used to stabilize the spine. Following stabilization, the pain was alleviated and the patient’s quality of life improved. We introduce here the 4-rod technique to stabilize the spine over 3 vertebral levels following severe destruction by metastatic tumor.

    To determine if new onset of low back pain in adults could be secondary to lumbar spondylolysis by establishing the age-related prevalence in the general population by examining patients undergoing computed tomography (CT) for reasons unrelated to back pain. The records of 2,555 patients who had undergone abdominal and pelvic CT in 2008 were reviewed electronically. In order to determine a true representation of the general population, we reviewed all indications for CT, excluding patients with a primary complaint of low back pain as the primary indication for imaging. Equal numbers of patients were separated into age groups by decade to ensure an even distribution of ages for statistical analysis. Patients older than 70 years were grouped together to provide case numbers comparable to those of the other decades. Logistic regression analysis was performed to evaluate the significance of the results. Three board-certified radiologists, including two musculoskeletal fellows and a radiology resident, retrospectively evaluated CT scans for lumbar spondylolysis, including unilateral and bilateral defects. Of the 2,555 cases evaluated, there were 203 positive cases of defects of the lumbar pars interarticularis. This corresponded to an overall prevalence of 8.0%. Prevalence per decade was fairly evenly distributed and ranged from 7.0%(ages 30-39 years) to 9.2% (ages 70 years and above). Prevalence of ages 20-49 years was 7.9%, and that of ages 50 years and older was 8.0%. Male to female ratio was 1.5:1. Logistic regression showed no significant increase in spondylolysis based on age. No significant increase in the prevalence of lumbar spondylolysis was demonstrated in patients older than 20 years. This suggests that the development of symptomatic lumbar pars defects do not occur in this population and should not be considered as a rare but potentially treatable cause of new onset low back pain in adults. This study demonstrated an overall prevalence of pars defects of 8

    An intradiploic CSF pseudocyst is a rare entity that has been described in association with trauma, as a sequela of untreated hydrocephalus, or occasionally as a congenital finding in older adults. The authors present the case of a woman with a remote history of a posterior fossa intradural procedure, in which she underwent Chiari malformation decompression, Silastic substitute-assisted duraplasty, and occipitocervical fusion; she presented 19 years later with recurrent symptoms of Chiari malformation. She was found to have an occipital intradiploic pseudomeningocele, arising within her dorsal occipitocervical fusion mass and resulting in dorsal hindbrain compression. She underwent a posterior fossa decompression and revision of her failed duraplasty, and she had a good recovery. This case demonstrates intradiploic CSF pseudomeningocele as a rare potential delayed complication of an intradural procedure for the treatment of Chiari malformation with occipitocervical fusion.

  7. Meralgia paresthetica-like syndrome may be caused by transient lumbar nerve root injury without definite compression: a case report.

    2010-12-01

    Meralgia paresthetica is a well-known sensory syndrome describing paresthesia and/or anesthesia in the anterolateral aspect of the thigh that is supplied by the lateral femoral cutaneous nerve. Compression of the nerve usually occurs at the point where it passes between the anterior superior iliac spine and the inguinal ligament. Proximal lesions such as lumbar radiculopathy, lumbar disc herniation, and spinal stenosis have been reported to cause meralgia paresthetica-like syndrome. These proximal lesions directly injure L2 and L3 spinal nerve roots and cause a constant compression of the nerve roots. The presented paper introduces a hypothesis that this syndrome can be caused by transient injury to the L2 and L3 nerve roots by the upper adjacent disc bulge without definite compression. This hypothesis is supported by lumbar spine magnetic resonance imaging of a patient presenting with a meralgia paresthetica-like symptom during bending forward and twisting of the body, showing no L2/L3 herniated disc but mildly posterior bulging of T12/L1 disc. This hypothesis emphasizes an importance of appropriate postures in patients with meralgia paresthetica-like symptoms in order to prevent long-term morbidity.

    Total paraplegia after epidural or spinal anesthesia is extremely rare. We herein report a case of total paraplegia caused by a giant intradural herniation of a lumbar disk at the L3-L4 level after total hip arthroplasty for coxarthrosis. The patient had no preoperative neurologic abnormalities. Intraoperative anesthetic management involved combined spinal-epidural anesthesia at the L3-L4 level with continuous intravenous propofol administration. Postoperatively, the patient complained of numbness and total paraplegia of the lower extremities. Magnetic resonance imaging showed a giant herniation of a lumbar disk compressing the spinal cord at the L3-L4 level. The intradural herniation was surgically treated, and the patient's symptoms completely resolved.

    A lesion of the lumbar posterior endplate is sometimes identified in the spinal canal of children and adolescents; it causes symptoms similar to those of a herniated disc. However, the pathology of the endplate lesion and the pathology of the herniated disc are different. We present a rare case of a 23-year-old woman who developed progressive palsy of the lower leg caused by huge lumbar posterior endplate lesion after recurrent disc herniation. PMID:27648326

    Full Text Available A lumbar peritoneal (LP shunt is a technique of cerebrospinal fluid (CSF diversion from the lumbar thecal sac to the peritoneal cavity. It is indicated under a large number of conditions such as communicating hydrocephalus, idiopathic intracranial hypertension, normal pressure hydrocephalus, spinal and cranial CSF leaks, pseudomeningoceles, slit ventricle syndrome, growing skull fractures which are difficult to treat by conventional methods (when dural defect extends deep in the cranial base or across venous sinuses and in recurrent cases after conventional surgery, raised intracranial pressure following chronic meningitis, persistent bulging of craniotomy site after operations for intracranial tumors or head trauma, syringomyelia and failed endoscopic third ventriculostomy with a patent stoma. In spite of the large number of indications of this shunt and being reasonably good, safe, and effective, very few reports about the LP shunt exist in the literature. This procedure did not get its due importance due to some initial negative reports. This review article is based on search on Google and PubMed. This article is aimed to review indications, complications, results, and comparison of the LP shunt with the commonly practiced ventriculoperitoneal (VP shunt. Shunt blocks, infections, CSF leaks, overdrainage and acquired Chiari malformation (ACM are some of the complications of the LP shunt. Early diagnosis of overdrainage complications and ACM as well as timely appropriate treatment especially by programmable shunts could decrease morbidity. Majority of recent reports suggest that a LP shunt is a better alternative to the VP shunt in communicating hydrocephalus. It has an advantage over the VP shunt of being completely extracranial and can be used under conditions other than hydrocephalus when the ventricles are normal sized or chinked. More publications are required to establish its usefulness in the treatment of wide variety of indications.

    Renal angiomyolipoma is a benign tumor formed by smooth muscle, adipose tissue and blood vessels. It is commonly found incidentally and its clinical manifestations are pain and abdominal mass or spontaneous tumor rupture with retroperitoneal bleeding. The clinical presentation of a hemorrhagic shock secondary to a retroperitoneal hematoma is uncommon. We report a 40 year-old male who presented to the emergency room with lumbar pain and deterioration of hemodynamic parameters. The CT scan showed a left renal injury associated to an expansive retroperitoneal process. The abdominal exploration, vascular control of the renal pedicle and nephrectomy allowed a successful outcome.

    A 10-year-old boy presented with a 7-day history of back pain and pyrexia. MRI showed an epidural abscess arising from septic arthritis in a lumbar facet joint. To our knowledge, there are only two previously reported cases of septic arthritis of a facet joint leading to an epidural abscess. This case illustrates how infection in a synovial joint may extend into the extradural space and might be the route of infection in more cases than has previously been recognised. (orig.)

    Full Text Available OBJECTIVE: The purpose of this study was to analyze the clinical features and prognostic factors of surgical outcome of foot drop caused by lumbar degenerative disease and put forward the clinical stage. METHODS: We retrospectively reviewed 135 patients with foot drop due to lumbar degenerative disease. The clinical features and mechanism were analyzed. Age, sex, duration of palsy, preoperative muscle strength of tibialis anterior (TA, sensation defect of affected lower limb, affected foot, diagnosis and compressed nerve roots were recorded and compared with surgical outcome. RESULTS: Foot drop was observed in 8.1% of all inpatients of lumbar degenerative disease. L5 nerve root compression was observed in 126 of all 135 patients (93.3%. Single, double and triple roots compression was observed respectively in 43, 83, and 9 patients (31.9%, 61.5%, and 6.6%. But there was no significant relationship between preoperative muscle strength of TA and the number of compressed roots. The muscle strength of TA was improved in 113 (83.7% patients after surgery, but it reached to >=4 in only 21 (15.6% patients. Improvement of the muscle strength of TA was almost stable at the 6-month follow-up. At the last follow-up, the muscle strength of TA was 1, 2, 3, 4, 5 respectively in 28, 24, 62, 13, 8 patients. Multivariate logistic regression showed duration of palsy (p=0.0360, OR=2.543, preoperative muscle strength of TA (p=0.0064, OR=5.528 and age (p=0.0309, OR=3.208 were factors that influenced recovery following an operation. CONCLUSIONS: L5 nerve root was most frequently affected. The muscle strength of TA improved in most patients after surgery, but few patients can get a good recovery from foot drop. Patients of shorter duration of palsy, better preoperative muscle strength of TA and younger age showed a better surgical outcome.

    Posterior lumbar subcutaneous (PLS) edema on spine magnetic resonance (MR) images is a common incidental, though neglected finding. This study was undertaken to investigate the relations between PLS edema and pathologic conditions. Between January and December 2009, 138 patients with PLS edema, but without a spinal tumor or a history of recent surgery or trauma, and 80 infectious spondylitis patients without PLS edema were enrolled in this retrospective study. Available medical records and lumbar spine MR images were evaluated. The degree of edema was quantified using an arbitrary scoring system. Further, the correlations between the degree of edema and age, sex, body mass index (BMI), degeneration of posterior spinal structures (PSS) and infectious spondylitis were analyzed. Of the 93 cases with a calculable BMI, 61 (66%) had a BMI of > 23 kg/m2. Correlations between the degree of edema and sex, age and BMI grade were all statistically non-significant. Thirty-three cases (24%) had an underlying disease, such as heart problem, diabetes mellitus, liver cirrhosis, chronic renal failure, extra-spinal tumor or connective tissue disorder. The numbers of cases with infectious spondylitis and an idiopathic condition was 61 (44%) and 44 (32%), respectively. The grade of infectious spondylitis was not found to be significantly associated with the degree of edema (p = 0.084). In cases with an idiopathic condition, the correlation between the degree of edema and PSS degeneration was statistically significant (p = 0.042). Radiologists should not disregard PLS edema, because it is related to an underlying disease and thus may be of clinical significance.

    2014-01-01

    Full Text Available Background: Schwannomas are tumors of peripheral nerves that develop from the nerve sheath. Foraminal schwannomas are rare and account for 1-5% of all spinal schwannomas. The lumbosacral root schwannoma is a rare cause of sciatica and may raise confusion in diagnosis with late discovery of the tumor. Case Description: We report the case of a patient 30 years of age with chronic left sciatica in whom lumbosacral magnetic resonance imaging (MRI revealed a  tumor involving the S1 nerve root. The excision of the tumor was simple. Histological examination revealed a benign schwannoma. The evolution was favorable postoperative with no neurological deficit, which confirms the good prognosis of this tumor. Conclusion: Nerve root schwannomas should be considered in the differential diagnosis of sciatica, especially when signs and symptoms of sciatica cannot be simply explained by prolapsed disc syndrome, which can often delay the diagnosis. Through this case presentation, the authors try to discuss the clinical and radiological features of this condition.

    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.

    Owing to the increasing population of elderly patients, a large number of patients with degenerative spondylosis are currently being surgically treated. Although basic measures for decreasing postoperative surgical infections (PSIs) are considered, it still remains among the leading causes of morbidity and mortality. The aim of this retrospective analysis is to present possible causes leading to PSI in patients who underwent surgery for lumbar degenerative spondylosis and highlight how it can be avoided to decrease morbidity and mortality. The study included 540 patients who underwent posterior stabilization due to degenerative lumbar stenosis between January 2013 and January 2014. The data before and after surgery was retrieved from the hospital charts. Patients with degenerative lumbar stenosis who were operated upon in this study had >2 levels of laminectomy and facetectomy. For this reason, posterior stabilization was performed for all the patients included in this study. Determining the causes of postoperative infection (PI) following spinal surgeries performed with instrumentation is a struggle. Seventeen different parameters that may be related to PI were evaluated in this study. The presence of systemic diseases, unknown glove perforations, and perioperative blood transfusions were among the parameters that increased the prevalence of PI. Alternatively, prolene sutures, double-layered gloves, and the use of rifampicin Sv (RIS) decreased the incidence of PI. Although the presence of systemic diseases, unnoticed glove perforations, and perioperative blood transfusions increased PIs, prolene suture material, double-layered gloves, and the use of RIS decreased PIs.

    Lumbar hernia is one of the rare cases that most surgeons are not exposed to. Hence the diagnosis can be easily missed. This leads to delay in the treatment causing increased morbidity. We report a case of lumbar hernia in a middle-aged woman. It was misdiagnosed as lipoma by another surgeon. It was a case of primary acquired lumbar hernia in the superior lumbar triangle. Clinical and MRI findings were correlated to reach the diagnosis. We also highlight the types, the process of diagnosis and the surgical repair of lumbar hernias. We wish to alert our fellow surgeons to keep the differential diagnosis of the lumbar hernia in mind before diagnosing any lumbar swelling as lipoma.

    We report the case of a 16-year-old boy with isolated septic arthritis of a lumbar facet. This rare presentation of an infection in a lumbar facet joint occurred after minor trauma sustained in a football game. Septic arthritis of the spinal facet joint is an uncommon phenomenon. Only 5 cases have been reported in immunocompromised pediatric patients. To our knowledge, no case of septic arthritis in an immunocompetent pediatric patient has been reported. An otherwise healthy 16-year-old boy presented with 4 weeks of escalating back pain after a minor athletics-related trauma. Evaluation showed incapacitating pain, lumbar musculature spasms, and the absence of fever, hemodynamic, or neurologic changes. Laboratory values were within normal limits. Magnetic resonance images showed a fluid collection within the L3-L4 facet and a localized abscess. Computed tomographic-guided aspiration showed methicillin-resistant Staphylococcus aureus infection, for which the patient received 6 weeks of vancomycin with complete resolution of symptoms. Refractory lumbago in an adolescent requires careful evaluation.

    Lumbar hernia is a rare condition. Lumbar hernia should be considered a rare differential diagnosis to unexplained back pain. Symptoms are scarce and diffuse and can vary with the size and content of the hernia. As there is a 25% risk of incarceration, operation is indicated even in asymptomatic hernias. We report a case of lumbar hernia in a woman with a slow growing mass in the lumbar region. She presented with pain and a computed tomography confirmed the diagnosis. She underwent open surgery and fully recovered with recurrence within the first half year.

    Study Design Case report. Objective To present a rare case of hydrocephalus following bilateral dumbbell-shaped C2 spinal neurofibromas resection and postoperative cervical pseudomeningocele in a patient with neurofibromatosis type 1 (NF1). Methods The patient's clinical course is retrospectively reviewed. A 37-year-old man affected by NF1 referred to our department for progressive weakness of both lower extremities and gait disturbance. Radiological imaging showed bilateral dumbbell-shaped C2 spinal neurofibromas. After its resection, at the 1-month follow-up evaluation, the patient reported headache and nausea. A CT brain scan showed a postoperative cervical pseudomeningocele and an increase in the ventricular sizes, resulting in hydrocephalus. Results A ventriculoperitoneal shunting was performed using a programmable valve opening pressure set to 120 mmH20. After surgery, the patient's neurological status markedly improved. Conclusion Hydrocephalus must be considered a possible complication of cervical spine tumor resection.

    We report an 84-year-old man with perforation caused by emphysematous cholecystitis who showed flare on the skin of the right dorsal lumbar region and intraperitoneal free gas. The patient was admitted for abdominal pain, abdominal swelling, and consciousness disorder 18 days after the onset. Abdominal computed tomography (CT) revealed emphysema in the gallbladder and a small amount of intraperitoneal free gas. Intraoperative findings suggested gangrenous cholecystitis. The gallbladder wall was perforated, and an abscess involving the right subphrenic region, the periphery of the liver and gallbladder, and the right paracolonic groove, was detected. The flare on the body surface may have reflected abscess formation in the right abdominal cavity. Emphysematous cholecystitis induces necrosis and perforation in many patients, and immediate strategies such as emergency surgery are important.

  9. SACRALISATION OF LUMBAR VERTEBRAE

    2014-06-01

    Full Text Available Background: Lumbar backache is a very common problem nowadays. Sacralisation of lumbar vertebrae is one of the cause for that. During routine osteology teaching a sacrum with incomplete attached lumbar 5 vertebrae is seen. Observation: Incompletely fused L 5 vertebrae with sacrum is seen. The bodies of the vertebrae are fused but the transverse process of left side is completely fused with the ala of sacrum.But on the right side is incompletely fused. Conclusion: The person is usually asymptomatic or may present with symptoms which include spinal or radicular pain, disc degeneration, L4/L5 disc prolapse, lumbar scoliosis and lumbar extradural defects. In transitional lumbosacral segmentation, it was observed that the lumbosacral intervertebral disc is significantly narrowed. The incidence of disc herniation is found to be higher and can occur even at young ages. There was also relationship established between transitional vertebrae and the degree of slippage in spondylolytic spondylolisthesis. In addition, this anomaly has known implications in the field of disc surgery.

    Lumbar spondylolisthesis is a common finding on plain radiographs. The condition has a variety of causes which can be differentiated on the basis of imaging findings. As the treatment is dependent upon the type of spondylolisthesis, it is important for the radiologist to be aware of these features. We present a pictorial review of the imaging features of lumbar spondylolisthesis and explain the differentiating points between different groups of this disorder. The relative merits of the different imaging techniques in assessing lumbar spondylolisthesis are discussed.

    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.

    Full Text Available Abstract Background Exposure of the anterior or lateral lumbar via the retroperitoneal approach easily causes injuries to the lumbar plexus. Lumbar plexus injuries which occur during anterior or transpsoas lumbar spine exposure and placement of instruments have been reported. This study aims is to provide more anatomical data and surgical landmarks in operations concerning the lumbar plexus in order to prevent lumbar plexus injuries and to increase the possibility of safety in anterior approach lumbar surgery. Methods To study the applied anatomy related to the lumbar plexus of fifteen formaldehyde-preserved cadavers, Five sets of Virtual Human (VH data set were prepared and used in the study. Three-dimensional (3D computerized reconstructions of the lumbar plexus and their adjacent structures were conducted from the VH female data set. Results The order of lumbar nerves is regular. From the anterior view, lumbar plexus nerves are arranged from medial at L5 to lateral at L2. From the lateral view, lumbar nerves are arranged from ventral at L2 to dorsal at L5. The angle of each nerve root exiting outward to the corresponding intervertebral foramen increases from L1 to L5. The lumbar plexus nerves are observed to be in close contact with transverse processes (TP. All parts of the lumbar plexus were located by sectional anatomy in the dorsal third of the psoas muscle. Thus, access to the psoas major muscle at the ventral 2/3 region can safely prevent nerve injuries. 3D reconstruction of the lumbar plexus based on VCH data can clearly show the relationships between the lumbar plexus and the blood vessels, vertebral body, kidney, and psoas muscle. Conclusion The psoas muscle can be considered as a surgical landmark since incision at the ventral 2/3 of the region can prevent lumbar plexus injuries for procedures requiring exposure of the lateral anterior of the lumbar. The transverse process can be considered as a landmark and reference in surgical

    Lumbar radiculopathy is generally caused by such well-recognized entity as lumbar disc herniation in neurosurgical practice; however rare pathologies such as thrombosed epidural varix may mimic them by causing radicular symptoms. In this case report, we present a 26-year-old man with the complaint of back and right leg pain who was operated for right L4-5 disc herniation. The lesion interpreted as an extruded disc herniation preoperatively was found to be a thrombosed epidural varix compressing the nerve root preoperatively. The nerve root was decompressed by shrinking the lesion with bipolar thermocoagulation and excision. The patient's complaints disappeared in the postoperative period. Thrombosed lumbar epidural varices may mimic lumbar disc herniations both radiologically and clinically. Therefore, must be kept in mind in the differential diagnosis of lumbar disc herniations. Microsurgical techniques are mandatory for the treatment of these pathologies and decompression with thermocoagulation and excision is an efficient method.

    Dynamic X-rays (DXR) are widely recognized as an effective method to detect lumbar instability (LI). They are usually performed with the patient in standing position (SDXR). In our opinion, standing position inhibits micromovements of the lumbar segment interested by the listhesis, thanks to paravertebral muscles antalgic contraction and augmented tone. We aim to demonstrate that DXR in recumbent position (RDXR), reducing the action of paravertebral muscles, can discover hypermovements not evidenced in SDXR. Between January 2011 and January 2013, we studied 200 consecutive patients with lumbar degenerative disease with MRI, SDXR, and RDXR. We aimed to find a correlation between low back or radicular pain and the presence of a spondylolisthesis not showed by the SDXR, but showed by the RDXR. We analysed 200 patients: of the 133 not pathologic in SDXR, 43 patients (32.3 %) showed an hypermovement in RDXR (p = 0.0001) without any significant correlation between hidden listhesis and age, sex, or level involved. The aim of our study is to determine whether in patients with lumbalgy without evidence of listhesis in SDXR, pain can be attributed to a faccettal syndrome or to a spondylolisthesis. Consequence of pain is augmented muscular tone of the paravertebral musculature, particularly in standing position. Augmented muscular tone tries to inhibit the pain generator, attempting to limit the slippage of the involved segment. In patients examined in RDXR, the tone of paravertebral musculature is reduced, showing the hidden spondylolisthesis. (orig.)

    Lumbar spinal stenosis is the most frequent reason for spinal surgery in patients over age 65 years. In this condition, narrowing of the lumbar spinal canal and nerve root canals leads to painful, debilitating compression of spinal nerves and blood vessels. As the population ages, an increasing number of patients will be diagnosed and treated for lumbar spinal stenosis by primary care providers. This article reviews the pathophysiology, diagnosis, and management of lumbar spinal stenosis in adults over age 50 years.

    Full Text Available 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.

    A series of 235 patients examined by lumbar CT because of sciatica or other low back disorder was studied. The need of additional examinations and correlations to surgical findings were evaluated. Inadequate information was the cause of additional examination, mostly myelography in 20 patients (8,5%). It was concluded that lumbar CT is a suitable first examination of the lumbar spine in sciatica and low back pain. The indications to complementary myelography and its benefit are discussed.

    Spondylolysis is an osseous defect of the pars interarticularis, thought to be a developmental or acquired stress fracture secondary to chronic low-grade trauma. It is encountered most frequently in adolescents, most commonly involving the lower lumbar spine, with particularly high prevalence among athletes involved in certain sports or activities. Spondylolysis can be asymptomatic or can be a cause of spine instability, back pain, and radiculopathy. The biomechanics and pathophysiology of spondylolysis are complex and debated. Imaging is utilized to detect spondylolysis, distinguish acute and active lesions from chronic inactive non-union, help establish prognosis, guide treatment, and to assess bony healing. Radiography with satisfactory technical quality can often demonstrate a pars defect. Multislice CT with multiplanar reformats is the most accurate modality for detecting the bony defect and may also be used for assessment of osseous healing; however, as with radiographs, it is not sensitive for detection of the early edematous stress response without a fracture line and exposes the patient to ionizing radiation. Magnetic resonance (MR) imaging should be used as the primary investigation for adolescents with back pain and suspected stress reactions of the lumbar pars interarticularis. Several imaging pitfalls render MR imaging less sensitive than CT for directly visualizing the pars defects (regional degenerative changes and sclerosis). Nevertheless, the presence of bone marrow edema on fluid-sensitive images is an important early finding that may suggest stress response without a visible fracture line. Moreover, MR is the imaging modality of choice for identifying associated nerve root compression. Single-photon emission computed tomography (SPECT) use is limited by a high rate of false-positive and false-negative results and by considerable ionizing radiation exposure. In this article, we provide a review of the current concepts regarding spondylolysis, its

    Lumbar hernias are rare clinical entities that often pose a challenge for repair. Because of the surrounding anatomy, adequate surgical herniorraphy is often difficult. Minimally invasive surgery has become an option for these hernias. Herein, we describe two patients with lumbar hernias (one with a recurrent traumatic hernia and one with an incisional hernia). Both of these hernias were successfully repaired laparoscopically.

    Full Text Available We present the case of a male patient with post traumatic retroperitoneal fibrosis whose main clinical expression was low-back pain. Diagnosis was established using CAT-scan and MRI, which revealed a large mass of soft tissue that almost entirely enveloped the abdominal aorta. Treatment with 40 mg of prednisone every 24 hours was established. This dose was reduced gradually, and progressive remission of clinical signs and symptoms was achieved, with a significant improvement of subsequent imaging-test results. Treatment was continued for one year. Two and a half years later the patient remains symptom-free, with no recurrence of his condition.Se presenta el caso de un paciente varón afecto de una fibrosis retroperitoneal postraumática, a cuyo diagnóstico se llegó a partir de dolor lumbar como síntoma principal. El diagnóstico se efectuó en base a los estudios mediante CT y RM, los cuales demostraron una gran masa de tejido de partes blandas que rodeaban la aorta. El tratamiento consistió en dosis de prednisona que inicialmente se instauró a 40 mg cada 24 horas, y posteriormente se fue reduciendo de forma gradual hasta la remisión de los signos y síntomas, y consecuentemente de los estudios de imagen. El tratamiento con corticoides se mantuvo durante un año. Dos años y medio el paciente está libre de síntomas sin recidiva de su proceso.

    2005-02-01

    Full Text Available Abstract 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.

    Traumatic lumbar hernias are very rare. Here, we present a case of secondary lumbar hernia. A 44-year-old man sustained a crushing injury. On admission, ecchymotic, fluctuating swelling was present on his left flank with normal vital signs. Subcutaneous intestinal segments were revealed at his left flank on abdominal CT. Emergency laparotomy revealed a 10-cm defect on the left postero-lateral abdominal wall. The splenic flexure was herniated through the defect. Herniated segments was reduced, the defect was repaired with a polypropylene mesh graft. There was also a serosal tear and an ischemic area 3mm wide on the splenic flexure and was repaired primarily. The patient had an uneventful recovery. Most traumatic lumbar hernias are caused by blunt trauma. Trauma that causes abdominal wall disruption also may cause intraabdominal organ injury. Abdominal CT is useful in the diagnosis and allows for diagnosis of coexisting organ injury. Emergency laparotomy should be performed to repair possible coexisting injuries.

    2016-01-01

    Abstract Rationale: Lumbar osteoid osteoma has a low incidence, which could easily lead to scoliosis. Patient concerns: Scoliosis secondary to lumbar osteoid osteoma could be easily misdiagnosed when patients do not complain of obvious symptoms. Diagnoses: We reported a case of a 9-year-old boy with back deformity that was firstly diagnosed with scoliosis at the local hospital. After prescribed with orthosis, the patient experienced aggravating pain that could not be relieved with painkillers. After he admitted to our hospital for further medical advice, he was prescribed to complete radiological examinations. Considering his radiological examination results and his medical history, correct diagnosis of lumbar osteoid osteoma was made. Interventions: Surgical intervention of posterior lesion resection was conducted after diagnosis. Intra-operative frozen pathology indicated features of osteoid osteoma. As the lesion involved inferior articular process of L5, which could cause lumbar instability after lesion resection, internal fixation was conducted at L4-S1 segment, and posterolateral bone fusion was also conducted at L5-S1 segment. Outcomes: Three months after operation, the patient showed marked improvement of scoliosis deformity and great relief of lumbar pain. Lessons subsections: Although spine osteoid osteoma is clinically rare, it shall not be overlooked when young patients present with scoliosis first. Radiological results including computed tomography and magnetic resonance imaging shall be taken carefully as reference when making diagnosis. Surgical intervention of lesion resection could well improve scoliosis and relieve lumbar pain. PMID:27893671

    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.

    Full Text Available The object of the study was to review the author’s large series of minimally invasive spine surgeries for complication rates. The author reviewed a personal operative database for minimally access spine surgeries done through nonexpandable tubular retractors for extradural, nonfusion procedures. Consecutive cases (n=1231 were reviewed for complications. There were no wound infections. Durotomy occurred in 33 cases (2.7% overall or 3.4% of lumbar cases. There were no external or symptomatic internal cerebrospinal fluid leaks or pseudomeningoceles requiring additional treatment. The only motor injuries were 3 C5 root palsies, 2 of which resolved. Minimally invasive spine surgery performed through tubular retractors can result in a low wound infection rate when compared to open surgery. Durotomy is no more common than open procedures and does not often result in the need for secondary procedures. New neurologic deficits are uncommon, with most observed at the C5 root. Minimally invasive spine surgery, even without benefits such as less pain or shorter hospital stays, can result in considerably lower complication rates than open surgery.

    Lumbar hernia is the protrusion of intraperitoneal or extraperitoneal contents through a defect of the posterolateral abdominal wall. Barbette was the first, in 1672, to suggest the existence of lumbar hernias. The first case was reported by Garangeot in 1731. Petit and Grynfeltt delineated the boundaries of the inferior and superior lumbar triangles in 1783 and 1866, respectively. These two anatomical sites account for about 95 per cent of lumbar hernias. Approximately 20 per cent of lumbar hernias are congenital. The rest are either primarily or secondarily acquired. The most common cause of primarily acquired lumbar hernias is increased intra-abdominal pressure. Secondarily acquired lumbar hernias are associated with prior surgical incisions, trauma, and abscess formation. During embryologic development, weakening of the area of the aponeuroses of the layered abdominal muscles that derive from somitic mesoderm, which invades the somatopleure, may potentially lead to lumbar hernias. Repair of lumbar hernias should be performed as early as possible to avoid incarceration and strangulation. The classic repair technique uses the open approach, where closure of the defect is performed either directly or using prosthetic mesh. The laparoscopic approach, either transabdominal or extraperitoneal, is an alternative.

    Degenerative disease of the lumbar spine is a common and increasingly prevalent condition that is often implicated as the primary reason for chronic low back pain and the leading cause of disability in the western world. Surgical management of lumbar degenerative disease has historically been approached by way of open surgical procedures aimed at decompressing and/or stabilizing the lumbar spine. Advances in technology and surgical instrumentation have led to minimally invasive surgical techniques being developed and increasingly used in the treatment of lumbar degenerative disease. Compared to the traditional open spine surgery, minimally invasive techniques require smaller incisions and decrease approach-related morbidity by avoiding muscle crush injury by self-retaining retractors, preventing the disruption of tendon attachment sites of important muscles at the spinous processes, using known anatomic neurovascular and muscle planes, and minimizing collateral soft-tissue injury by limiting the width of the surgical corridor. The theoretical benefits of minimally invasive surgery over traditional open surgery include reduced blood loss, decreased postoperative pain and narcotics use, shorter hospital length of stay, faster recover and quicker return to work and normal activity. This paper describes the different minimally invasive techniques that are currently available for the treatment of degenerative disease of the lumbar spine. PMID:25610845

    Boody, Barrett S; Savage, Jason W

    2016-12-01

    Lumbar facet cysts are a rare but increasingly common cause of symptomatic nerve root compression and can lead to radiculopathy, neurogenic claudication, and cauda equina syndrome. The cysts arise from the zygapophyseal joints of the lumbar spine and commonly demonstrate synovial herniation with mucinous degeneration of the facet joint capsule. Lumbar facet cysts are most common at the L4-L5 level and often are associated with spondylosis and degenerative spondylolisthesis. Advanced imaging studies have increased diagnosis of the cysts; however, optimal treatment of the cysts remains controversial. First-line treatment is nonsurgical management consisting of oral NSAIDs, physical therapy, bracing, epidural steroid injections, and/or cyst aspiration. Given the high rate of recurrence and the relatively low satisfaction with nonsurgical management, surgical options, including hemilaminectomy or laminotomy to excise the cyst and decompress the neural elements, are typically performed. Recent studies suggest that segmental fusion of the involved levels may decrease the risks of cyst recurrence and radiculopathy.

    2013-01-01

    Concerning the Modic change of lumbar spinal endplate, the Modic change types, forming causes, and the relationship between Modic change and degenerative lumbar diseases have been studied from anatomy, pathology, molecular biology and many other aspects at present. The degeneration of lumbar disc is a high risk factor of the Modic change. The degeneration of lumbar disc usually starts from cartilage endplate degeneration. The injury of cartilage endplate could accelerate the degeneration of lumbar disc. This article reviews the significance of Modic change of lumbar spinal endplate in lumbar disc degeneration. The cause of Modic change of the endplate, pathological change, the influence of inflammatory mediators on the endplate and the significance of Modic change in the treatment of degenerative lumbar diseases are summarized to analyze the relationship between the degeneration of lumbar disc and Modic change of endplate and to describe the influence of Modic change in the treatment of degenerative lumbar disc diseases.

    Hughes, Alexander; Girardi, Federico; Sama, Andrew; Lebl, Darren; Cammisa, Frank

    2015-01-01

    The lateral lumbar interbody fusion (LLIF) is a relatively new technique that allows the surgeon to access the intervertebral space from a direct lateral approach either anterior to or through the psoas muscle. This approach provides an alternative to anterior lumbar interbody fusion with instrumentation, posterior lumbar interbody fusion, and transforaminal lumbar interbody fusion for anterior column support. LLIF is minimally invasive, safe, better structural support from the apophyseal ring, potential for coronal plane deformity correction, and indirect decompression, which have has made this technique popular. LLIF is currently being utilized for a variety of pathologies including but not limited to adult de novo lumbar scoliosis, central and foraminal stenosis, spondylolisthesis, and adjacent segment degeneration. Although early clinical outcomes have been good, the potential for significant neurological and vascular vertebral endplate complications exists. Nevertheless, LLIF is a promising technique with the potential to more effectively treat complex adult de novo scoliosis and achieve predictable fusion while avoiding the complications of traditional anterior surgery and posterior interbody techniques.

    Ventriculoperitoneal (VP) shunt placement is the mainstay of treatment for hydrocephalus, yet shunts remain vulnerable to a variety of complications. Although fat droplet migration into the subarachnoid space and cerebrospinal fluid pathways following craniotomy has been observed, a VP shunt obstruction with fat droplets has never been reported to our knowledge. We present the first reported case of VP shunt catheter obstruction by migratory fat droplets in a 55-year-old woman who underwent suboccipital craniotomy for removal of a metastatic tumor of the left medullocerebellar region, without fat harvesting. A VP shunt was inserted 1month later due to communicating hydrocephalus. The patient presented with gait disturbance, intermittent confusion, and pseudomeningocele 21days after shunt insertion. MRI revealed retrograde fat deposition in the ventricular system and VP shunt catheter, apparently following migration of fat droplets from the fatty soft tissue of the craniotomy site. Spinal tap revealed signs of aseptic meningitis. Steroid treatment for aseptic "lipoid" meningitis provided symptom relief. MRI 2months later revealed partial fat resorption and resolution of the pseudomeningocele. VP shunt malfunction caused by fat obstruction of the ventricular catheter should be acknowledged as a possible complication in VP shunts after craniotomy, even in the absence of fat harvesting.

    Traumatic lumbar hernia describes the extrusion of intraperitoneal or extraperitoneal contents through a defect in the posterolateral abdominal wall caused by a trauma. This is a rare entity and usually diagnosed by computed tomography. A 64-year-old male received an injury on his cervical spinal cord after an accident in which he fell down. He complained of a mass on his left posterolateral back area. We diagnosed the mass as a traumatic lumbar hernia by ultrasonography and confirmed it by computed tomography. We conclude that the ultrasonography can be a useful diagnostic tool for traumatic lumbar hernia

Epidurography is considered more suitble than radiculomyelogrphy for assessing this condition because narrowing of the epidural space and compression of the nerve roots, due to osteofibrous changes at the lysis, are more consistently demonstrated.

    Low back pain is a common presenting complaint to sports medicine providers. The lumbar spine is a complex anatomic structure with multiple potential pain generators. Epidemiologic studies have shown that the intervertebral disc is the most common pain generator in all patients with low back pain. The facet joints may account for 15%-40% of low back pain. It can be challenging at times to establish a firm diagnosis of facet pain. Facet pain can have different presentations, and pain emanating from other lumbopelvic structures can present similarly as facet joint pain. This article reviews the anatomy and biomechanics of the lumbar facet joints, presenting symptoms and physical examination findings seen with facet pain. We also will discuss diagnostic and treatment paradigms that are helpful to the clinician treating low back pain in athletes.

    2012-01-01

    Cauda equina syndrome is a well described state of neurologic compromise due to lumbosacral root compression. In most cases, it is due to a herniated disc, tumor, infection, or hematoma. We report a case of rapid lumbar synovial cyst expansion leading to acute cauda equina syndrome and compare it to similar cases in the literature. The patient is a 49-year-old woman with a history of chronic low back pain who developed cauda equina syndrome. Serial lumbar magnetic resonance imaging studies demonstrated a significant increase in the size of a lumbar synovial cyst over a 2 week interval. After an unsuccessful attempt to relieve her acute symptoms with computed tomography-guided cyst aspiration, an L4-5 posterior spinal decompression with excision of the synovial cyst was performed. Postoperatively the patient's perineal numbness, bladder incontinence, and associated pain complaints resolved. The only residual symptom at one month follow-up was continued numbness in the right lower limb in an L5 distribution. This report adds to 6 other well described similar cases found in the literature by illustrating several important points. First, a lumbar synovial cyst is a rare but possible cause of acute cauda equina syndrome. Second, magnetic resonance imaging is the test of choice to diagnose and characterize lumbar synovial cysts; serial imaging can detect fluctuations in cyst size. Third, percutaneous treatment of lumbar synovial cysts is variable in efficacy and proved to be unsuccessful in our patient. Finally, surgical management has shown high success rates for symptomatic cysts. Specifically, in the setting of acute cauda equina syndrome secondary to a lumbar synovial cyst, urgent surgical decompression has led to resolution of neurologic symptoms in most reported cases. A lumbar synovial cyst is an uncommon cause of acute cauda equina syndrome. Prompt diagnosis and treatment may lead to reduced morbidity associated with this condition.

    Background Low back pain is a frequent condition that results in substantial disability and causes admission of patients to neurosurgery clinics. To evaluate and present the therapeutic outcomes in lumbar disc hernia (LDH) patients treated by means of a conservative approach, consisting of bed rest and medical therapy. Methods This retrospective cohort was carried out in the neurosurgery departments of hospitals in Kahramanmaraş city and 23 patients diagnosed with LDH at the levels of L3−L4, L4−L5 or L5−S1 were enrolled. Results The average age was 38.4 ± 8.0 and the chief complaint was low back pain and sciatica radiating to one or both lower extremities. Conservative treatment was administered. Neurological examination findings, durations of treatment and intervals until symptomatic recovery were recorded. Laségue tests and neurosensory examination revealed that mild neurological deficits existed in 16 of our patients. Previously, 5 patients had received physiotherapy and 7 patients had been on medical treatment. The number of patients with LDH at the level of L3−L4, L4−L5, and L5−S1 were 1, 13, and 9, respectively. All patients reported that they had benefit from medical treatment and bed rest, and radiologic improvement was observed simultaneously on MRI scans. The average duration until symptomatic recovery and/or regression of LDH symptoms was 13.6 ± 5.4 months (range: 5−22). Conclusions It should be kept in mind that lumbar disc hernias could regress with medical treatment and rest without surgery, and there should be an awareness that these patients could recover radiologically. This condition must be taken into account during decision making for surgical intervention in LDH patients devoid of indications for emergent surgery. PMID:28119770

    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.

  13. Laparoscopic transabdominal extraperitoneal repair of lumbar hernia

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available Lumbar hernias need to be repaired due to the risk of incarceration and strangulation. A laparoscopic intraperitoneal approach in the modified flank position causes the intraperitoneal viscera to be displaced medially away from the hernia. The creation of a wide peritoneal flap around the hernial defect helps in mobilization of the colon, increased length of margin is available for coverage of mesh and more importantly for secure fixation of the mesh under vision to the underlying fascia. Laparoscopic lumbar hernia repair by this technique is a tensionless repair that diffuses total intra-abdominal pressure on each square inch of implanted mesh. The technique follows current principles of hernia repair and appears to confer all benefits of a minimal access approach.

    A 82-year-old woman suffered from a metastatic lesion of follicular carcinoma of the thyroid to the fourth lumbar spine, which compressed the spinal nerves and caused lumbar pain and paresthesis of the lower limb. External irradiation, 5200 RAD, was carried out. Total thyroidectomy was done for the preparation of radioiodine(131I) therapy. Two weeks later, embolization of lumbar arteries was performed to prevent the progression of the spinal cord damage during a period waiting for 131I administration. The size of the lumbar lesion decreased, and lumbal pain and spinal cord symptoms disappeared. After administration of 131I, the metastatic lesion became further smaller.

    Lumbar spinal stenosis (LSS) is a narrowing of the spinal canal that causes mechanical compression of the spinal nerve roots. The compression of these nerve roots can cause leg pain, as well as neurogenic claudication. Lumbar epidural steroid injections have commonly been used in patients with LSS. The aim of our study was to determine the relationship between the severity of LSS using a grading system (grade 1 = mild stenosis with separation of all cauda equina; grade 2 = moderate stenosis with some cauda equina aggregated; grade 3 = severe stenosis with none of the cauda equina separated) and the subject's response to computed tomography-guided lumbar epidural steroid injection (CTG-LESI) and to evaluate the short-term effectiveness. Forty-seven consecutive patients with degenerative LSS were enrolled in this prospective study. All subjects underwent lumbar spine magnetic resonance imaging. Two radiologists independently graded lumbar central canal stenosis based on T2-weighted axial images. All CTG-LESI were performed in the procedure room. Outcome measures were obtained using the 5-point patient's satisfaction scale at 2 and 8 weeks post-treatment. To evaluate the outcome, we divided the patients into two groups according to their response to the treatment. Improvement (including reports of slightly improved, much improved, and no pain) was observed in 37 patients (78.7%) at 2 weeks and 36 patients (77.6%) at 8 weeks after the procedure. There was no statistically significant correlation between pain relief and age. The grade of LSS appears to have no effect on the degree of pain relief associated with CTG-LESI. However, CTG-LESI seems to provide effective short-term pain relief due to LSS. Wiley Periodicals, Inc.

    Full Text Available This case report details an interesting case of suspected spinal bifida in an obstetric patient who presented for an elective cesarean section. A large scarred/dimpled area, surrounded by significant hair growth in the region of the lumbar spine had been missed in multiple antenatal and preoperative assessments and was recognized on the day of the surgery as the patient was being prepared for spinal anesthesia. The patient was uncertain regarding the pathology of the lesion, and all investigations relating to this had been undertaken in Pakistan where she lived as a child. General anesthesia was undertaken because magnetic resonance imaging had not been performed and tethering of the spinal cord could not be ruled out clinically. The patient suffered from significant blood loss intra and postoperatively, requiring a two unit blood transfusion. She was discharged after 5 days in the hospital. This case highlights the need for thorough examination in all obstetric patients presenting to the preoperative clinic, focusing on the airway, vascular access, and lumbar spine. Patients may not always disclose certain information due to a lack of understanding, embarrassment, forgetfulness, or language barriers. Significant aspects of their care may have been undertaken abroad and access to these notes is often limited. Preoperative detection of the lesion would have allowed further investigation and imaging of the lesion and enabled more comprehensive discussions with the patient regarding anesthetic options and risk.

    Lumbar or sacral nerve root compression is most commonly caused by intervertebral disc degeneration and/or herniation. Less frequently, other extradural causes may be implicated, such as infection, neoplasm, epidural hematoma, or ligamentum flavum pathology. We present the case of a patient with spontaneous ligamentum flavum hematoma compressing the L4 nerve root, without antecedent trauma. Although exceedingly rare, the diagnosis of ligamentum flavum pathology in general, and that of ligamentum flavum hematoma in particular, should be considered on those rare occasions when the etiology of lumbar or sacral nerve root compressions appears enigmatic on radiological studies. Usually surgical treatment produces excellent clinical outcome. (orig.)

    2011-12-01

    Intrathecal spinal catheters (lumbar drains) are indicated for several medical and surgical conditions. In neurosurgical procedures, they are used to reduce intracranial and intrathecal pressures by diverting CSF. They have also been placed for therapeutic access to administer drugs, and more recently, vascular surgeons have used them to improve spinal cord perfusion during the treatment of thoracic aortic aneurysms. Insertion of these lumbar drains is not without attendant complications. One complication is the shearing of the distal end of the catheter with a resultant retained fragment. The authors report the case of a 65-year-old man who presented with a subarachnoid hemorrhage due to the migration of a retained lumbar drain that sheared off during its removal. To the best of the authors' knowledge, this is the first case of rostral migration of a retained intrathecal catheter causing subarachnoid hemorrhage. The authors review the literature on retained intrathecal spinal catheters, and their findings support either early removal of easily accessible catheters or close monitoring with serial imaging.

    Several risk factors and causes of adjacent segment disease have been debated; however, no quantitative relationship to spino-pelvic parameters has been established so far. A retrospective case-control study was carried out to investigate spino-pelvic alignment in patients with adjacent segment disease compared to a control group. 45 patients (ASDis) were identified that underwent revision surgery for adjacent segment disease after on average 49 months (7-125), 39 patients were selected as control group (CTRL) similar in the distribution of the matching variables, such as age, gender, preoperative degenerative changes, and numbers of segments fused with a mean follow-up of 84 months (61-142) (total n = 84). Several radiographic parameters were measured on pre- and postoperative radiographs, including lumbar lordosis measured (LL), sacral slope, pelvic incidence (PI), and tilt. Significant differences between ASDis and CTRL groups on preoperative radiographs were seen for PI (60.9 ± 10.0° vs. 51.7 ± 10.4°, p = 0.001) and LL (48.1 ± 12.5° vs. 53.8 ± 10.8°, p = 0.012). Pelvic incidence was put into relation to lumbar lordosis by calculating the difference between pelvic incidence and lumbar lordosis (∆PILL = PI-LL, ASDis 12.5 ± 16.7° vs. CTRL 3.4 ± 12.1°, p = 0.001). A cutoff value of 9.8° was determined by logistic regression and ROC analysis and patients classified into a type A (∆PILL lordosis mismatch. In type A spino-pelvic alignment, 25.5 % of patients underwent revision surgery for adjacent segment disease, whereas 78.3 % of patients classified as type B alignment had revision surgery. Classification of patients into type A and B alignments yields a sensitivity for predicting adjacent segment disease of 71 %, a specificity of 81 % and an odds ratio of 10.6. In degenerative disease of the lumbar spine a high pelvic incidence with diminished lumbar lordosis seems to predispose to adjacent segment disease. Patients with such pelvic incidence-lumbar

    The aim of this paper was to systematically review the diagnostic ability of clinical tests to detect lumbar spondylolysis and spondylolisthesis. A systematic literature search of six databases, with no language restrictions, from 1950 to 2014 was concluded on February 1, 2014. Clinical tests were required to be compared against imaging reference standards and report, or allow computation, of common diagnostic values. The systematic search yielded a total of 5164 articles with 57 retained for full-text examination, from which 4 met the full inclusion criteria for the review. Study heterogeneity precluded a meta-analysis of included studies. Fifteen different clinical tests were evaluated for their ability to diagnose lumbar spondylolisthesis and one test for its ability to diagnose lumbar spondylolysis. The one-legged hyperextension test demonstrated low to moderate sensitivity (50%-73%) and low specificity (17%-32%) to diagnose lumbar spondylolysis, while the lumbar spinous process palpation test was the optimal diagnostic test for lumbar spondylolisthesis; returning high specificity (87%-100%) and moderate to high sensitivity (60-88) values. Lumbar spondylolysis and spondylolisthesis are identifiable causes of LBP in athletes. There appears to be utility to lumbar spinous process palpation for the diagnosis of lumbar spondylolisthesis, however the one-legged hyperextension test has virtually no value in diagnosing patients with spondylolysis.

    Full Text Available Swinging a golf club includes the rotation and extension of the lumbar spine. Golf-related low back pain has been associated with degeneration of the lumbar facet and intervertebral discs, and with spondylolysis. Reflective markers were placed directly onto the skin of 11young male amateur golfers without a previous history of back pain. Using a VICON system (Oxford Metrics, U.K., full golf swings were monitored without a corset (WOC, with a soft corset (SC, and with a hard corset (HC, with each subject taking 3 swings. Changes in the angle between the pelvis and the thorax (maximum range of motion and angular velocity in 3 dimensions (lumbar rotation, flexion-extension, and lateral tilt were analyzed, as was rotation of the hip joint. Peak changes in lumbar extension and rotation occurred just after impact with the ball. The extension angle of the lumbar spine at finish was significantly lower under SC (38° or HC (28° than under WOC (44° conditions (p < 0.05. The maximum angular velocity after impact was significantly smaller under HC (94°/sec than under SC (177°/sec and WOC (191° /sec conditions, as were the lumbar rotation angles at top and finish. In contrast, right hip rotation angles at top showed a compensatory increase under HC conditions. Wearing a lumbar corset while swinging a golf club can effectively decrease lumbar extension and rotation angles from impact until the end of the swing. These effects were significantly enhanced while wearing an HC

    Intradural disc herniation is a rare complication of degenerative disc disease. A correct diagnosis of this process is frequently difficult. If this entity is not preoperatively diagnosed and is omitted at surgery, severe neurologic sequels may be provoked. We report a case of a pathologically proven intradural disc herniation preoperatively diagnosed by MR imaging. Clinically, it was manifested by sudden onset of right leg ciatalgia and progressive right lower extremity weakness. The patient also referred a one-month history of sexual dysfunction. MR imaging revealed interruption of the low signal of the anulus fibrosus and of the posterior longitudinal ligament at L2-L3 level and a voluminous disc fragment migrated in the dural sac that showed rim enhancement with gadolinium.The clinical, neuroradiological, and surgical management of lumbar intradural disc herniation are reviewed.

  7. Transforaminal ligament may play a role in lumbar nerve root compression of foraminal stenosis.

    Science.gov (United States)

    Qian, Yu; Qin, An; Zheng, Ming H

    2011-12-01

    Lumbar foraminal stenosis is a common pathological change, and lumbar nerve root compression in stenotic foramina was recently considered as one of the main causes of low back pain and leg pain. However, the exact mechanism of lumbar nerve root compression in foramina is still not clear. Previous studies indicated that loss of the intervertebral disc height could reduce the cross-sectional area of lumbar foramina, while lumbar nerve root compression by boundaries of foramina has not been observed in experimental reduction of the intervertebral disc height. Given the close anatomic relationship between transforaminal ligaments and lumbar nerve roots, we hypothesize that transforaminal ligament can be the leading cause of lumbar nerve root compression in foraminal stenosis. We also propose that there are two possible mechanisms of lumbar nerve root compression by transforaminal ligaments: (1) nerve roots are compressed by the transforaminal ligament which moves downward with the loss of the intervertebral disc height; (2) pathological transforaminal ligaments increase the risk of nerve root compression in foramina.

SL did not change significantly (11.4:11.06, p=0.85. There were no significant differences when comparing patients who received crescent shaped cage (n=27 and rectangular cage (n=43. Hypolordotic patients (Roussouly types 1 and 2 had radiographic improvement in comparison to normolordotic and hyperlordotic groups (types 3 and 4. Conclusion : Minimally invasive lumbar interbody fusion caused reduction in lumbosacral parameters. Cage shape had no influence on the results.

    Full Text Available We report psoas hematoma communicating with extradural hematoma and compressing on lumbar nerve roots during the postoperative period in a patient who underwent L3/4 level dynamic stabilization and L4/5 and L5/S1 posterior lumbar interbody fusion. Persistent radicular symptoms occurring soon after posterior lumbar surgery are not an unknown entity. However, psoas hematoma communicating with the extradural hematoma and compressing on L4 and L5 nerve roots soon after surgery, leading to radicular symptoms has not been reported. In addition to the conservative approach in managing such cases, this case report also emphasizes the importance of clinical evaluation and utilization of necessary imaging techniques such as computed tomography (CT scan and magnetic resonance imaging (MRI scan to diagnose the cause of persistent severe radicular pain in the postoperative period.

    Lateral lumbar disc herniations (L.D.H.) develop in the foramen, and compress the nerve root against the overlying vertebral pedicle. In our study of L.D.H. from the clinical, radiographical, and therapeutical aspects, we reviewed 23 cases selected from the 590 patients treated for discal herniation from 1984 to 1987. The frequency of L.D.H. in this series was 3.8 per cent. The clinical pattern brings out some suggestive signs of L.D.H. (frequency of cruralgia, a seldom very positive Lasegue's test, the paucity of spinal signs, non impulsive pain). Saccoradiculography and discography rarely evidenced the L.D.H.. The T.D.M. was the investigation of choice on condition that it was correctly used. When the image was doubtful, disco-CT confirmation should be proceeded too. This latter method of investigation enabled the possibility of sequestration to be explored. 14 patients were treated by chemonucleolysis, with 9 successful outcomes. The 5 failures were cases where chemonucleolysis should not have been indicated, mainly due to associated osseous stenosis. 9 patients underwent immediate surgery with good results in each case.

    2004-03-01

    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. The majority of LSS patients were unable

    2007-01-01

    BACKGROUND: Lumbar hernia is a rare congenital or acquired defect of the posterior abdominal wall. The acquired type is more common and occurs mainly as an incisional defect after lfank surgery. Incarceration or strangulation of hernia contents is uncommon. METHOD: Segmental liver incarceration through a recurrent incisional lumbar defect was diagnosed in a 58 years old woman by magnetic resonance imaging. RESULTS: The patient underwent an open repair of the com-plicated hernia. An expanded polytetralfouoroethylene (e-PTFE) mesh was fashioned as a sublay prosthesis. She had an uncomplicated postoperative course. Follow-up examinations revealed no evidence of recurrence. CONCLUSIONS: Although lumbar hernia rarely results in incarceration or strangulation, early repair is necessary because of the risks of complications and the increasing dififculty in repairment as it enlarges. Surgical repair is often dififcult and challenging.

    OBJECTIVE The flexed posture of the proximal (L1-3) or distal (L4-S1) lumbar spine increases the diameter of the spinal canal and neuroforamina and can relieve symptoms of neurogenic claudication. Distal lumbar flexion can result in pelvic retroversion; therefore, in cases of flexible sagittal imbalance, pelvic retroversion may be compensatory for lumbar stenosis and not solely compensatory for the sagittal imbalance as previously thought. The authors investigate underlying causes for pelvic retroversion in patients with flexible sagittal imbalance. METHODS One hundred thirty-eight patients with sagittal imbalance who underwent a total of 148 fusion procedures of the thoracolumbar spine were identified from a prospective clinical database. Radiographic parameters were obtained from images preoperatively, intraoperatively, and at 6-month and 2-year follow-up. A cohort of 24 patients with flexible sagittal imbalance was identified and individually matched with a control cohort of 23 patients with fixed deformities. Flexible deformities were defined as a 10° change in lumbar lordosis between weight-bearing and non-weight-bearing images. Pelvic retroversion was quantified as the ratio of pelvic tilt (PT) to pelvic incidence (PI). RESULTS The average difference between lumbar lordosis on supine MR images and standing radiographs was 15° in the flexible cohort. Sixty-eight percent of the patients in the flexible cohort were diagnosed preoperatively with lumbar stenosis compared with only 22% in the fixed sagittal imbalance cohort (p = 0.0032). There was no difference between the flexible and fixed cohorts with regard to C-2 sagittal vertical axis (SVA) (p = 0.95) or C-7 SVA (p = 0.43). When assessing for postural compensation by pelvic retroversion in the stenotic patients and nonstenotic patients, the PT/PI ratio was found to be significantly greater in the patients with stenosis (p = 0.019). CONCLUSIONS For flexible sagittal imbalance, preoperative attention should

    Sciatica is commonly caused by lumbar prolapsed intervertebral disc (PID) and other spinal lesions. Uncommon causes like nerve root schwannoma are rarely considered in the differential diagnosis of sciatica. Spinal schwannomas occur both sporadically and in association with neurofibromatosis type 1 (NF1; von Recklinghausen's disease). This case report describes lumbar foraminal schwannoma as an unusual cause of radiculopathy, presenting clinically as a lumbar disc prolapse. The diagnosis was confirmed on MRI scan. Patient had complete symptomatic recovery following surgical enucleation of the tumour mass from the L5 nerve root. This case report is of particular interest as it highlights the diagnostic confusion, which is bound to arise, because the clinical presentation closely mimics a lumbar PID. This often leads to delay in diagnosis and “failure of conservative treatment.” PMID:23259107

    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.

    A retrospective cross-sectional study was designed to evaluate total sagittal spinal alignment in patients with lumbar disc herniation (LDH) and healthy subjects. Abnormal sagittal spinal alignment could cause persistent low back pain in lumbar disease. Previous studies analyzed sciatic scoliotic list in patients with lumbar disc herniation; but there is little or no information on the relationship between sagittal alignment and subjective findings. The study subjects were 61 LDH patients and 60 age-matched healthy subjects. Preoperative and 6-month postoperatively lateral whole-spine standing radiographs were assessed for the distance between C7 plumb line and posterior superior corner on the top margin of S1 sagittal vertical axis (SVA), lumbar lordotic angle between the top margin of the first lumbar vertebra and first sacral vertebra (L1S1), pelvic tilting angle (PA), and pelvic morphologic angle (PRS1). Subjective symptoms were evaluated by the Japanese Orthopedic Association (JOA) score for lower back pain (nine points). The mean SVA value of the LDH group (32.7 +/- 46.5 mm, +/- SD) was significantly larger than that of the control (2.5 +/- 17.1 mm), while L1S1 was smaller (36.7 +/- 14.5 degrees ) and PA was larger (25.1 +/- 9.0 degrees ) in LDH than control group (49.0 +/- 10.0 degrees and 18.2 +/- 6.0 degrees , respectively). At 6 months after surgery, the malalignment recovered to almost the same level as the control group. SVA correlated with the subjective symptoms measured by the JOA score. Sagittal spinal alignment in LDH exhibits more anterior translation of the C7 plumb line, less lumbar lordosis, and a more vertical sacrum. Measurements of these spinal parameters allowed assessment of the pathophysiology of LDH.

    Lumbar synovial cysts can result from spondylosis of facet joints. These cysts can encroach on adjacent nerve roots, causing symptoms of radiculopathy. Currently the only definitive treatment for these symptoms is surgery, which may involve laminectomy or laminotomy, with or without spinal fusion. Surgery has been reported to successfully relieve radicular pain in 83.5% of patients by Zhenbo et al. Little information is available concerning the efficacy and outcome of percutaneous fluoroscopic synovial cyst rupture for treatment of facet joint synovial cysts. The goal of this investigation was to assess the efficacy of fluoroscopically guided lumbar synovial cyst rupture, in particular for its relief of radicular symptoms and its potential to reduce the need for surgical intervention. Retrospective evaluation of a case series. University hospital and urban public health care system. With approval from the Institutional Review Board of Case Western Reserve University/ MetroHealth Medical Center, we reviewed the medical charts of patients with lumbar radiculopathy who underwent percutaneous lumbar synovial cyst rupture. The 30 patients in the cohort were treated by one pain specialist between 2006 and 2013. These patients were diagnosed with moderate to severe lower back pain, radiculopathy, and ranged in age from 42 to 80 years. Patients were followed up for a minimum of 6 months and up to 24 months. Pre- and post-procedure pain assessments were reviewed by clinical chart review. In addition post-procedure pain assessments and duration of pain relief were obtained with telephone interviews. Pain had been reported by the patients using a numeric rating scale of 0 - 10 (0 = no pain; 10 = worst possible pain). Charts were reviewed to determine if surgery was eventually performed to correct radicular symptoms. More than 6 months of pain relief was achieved in 14/30 patients (46%) and between one and 6 months of pain relief was achieved in 7/30 patients (23.3%). Nine

    T1- and T2-weighted magnetic resonance images (MRI) can reveal lumbar redundant nerve roots (RNRs), a result of chronic compression and nerve elongation associated with pathogenesis of cauda equina claudication (CEC) in degenerative lumbar canal stenosis (DLCS). The study investigated effects of lumbar lordosis angle and range of motion on functional recovery in lumbar stenosis patents with and without RNRs. A retrospective study was conducted of 93 lumbar spinal stenosis patients who underwent decompressive surgery. Eligible records were assessed by 3 independent blinded radiologists for presence or absence of RNRs on sagittal T2-weighted MR (RNR and non-RNR groups), pre- and post-operative JOA score, lumbar lordosis angle, and range of motion. Of 93 total patients, the RNR group (n=37, 21/37 female) and non-RNR group (n=56; 31/56 female) had similar preoperative conditions (JOA score) and were not significantly different in age (mean 64.19 ± 8.25 vs. 62.8 ± 9.41 years), symptom duration (30.92 ± 22.43 vs. 28.64 ± 17.40 months), or follow-up periods (17.35 ± 4.02 vs. 17.75 ± 4.29 mo) (all p>0.4). The non-RNR group exhibited significantly better final JOA score (p=0.015) and recovery rate (p=0.002). RNR group patients exhibited larger lumbar lordosis angles in the neutral position (p=0.009) and extension (p=0.021) and larger range of motion (p=0.008). Poorer surgical outcomes in patients with RNRs indicated that elevated lumbar lordosis angle and range of motion increased risks of RNR formation, which in turn may cause poorer post-surgical recovery, this information is possibly useful in prognostic assessment of lumbar stenosis complicated by RNRs.

As radiologists, we tend to focus on the technical aspects of a procedure and the anatomic/morphologic information it provides. However, it cannot be emphasized enough that when performing lumbar discography, the assessment of the patient's pain response during the injection is the most important component of the procedure, and requires not only technical skills, but an understanding of how best to avoid some of the pitfalls that can lead to inaccurate results.

    A lumbar disc surgery predictive score card or questionnaire has been developed to assess potential candidates for excision of a herniated lumbar disc who have not previously undergone lumbar spine surgery. It is not designed to encompass patients who are being considered for other types of lumbar spine surgery, such as decompressive laminectomy or fusion. In an effort to make the "score card" usable by almost all physicians who are involved in lumbar disc surgery, only studies which have broad acceptance and are generally employed are included. Studies which have less widespread use such as electromyogram, discogram, venogram, special psychologic studies (MMPI, pain drawings) have been purposely excluded.

  12. Influence of lumbar curvature and rotation on forward flexibility in idiopathic scoliosis

    Directory of Open Access Journals (Sweden)

    Feng-Chun Kao

    2014-04-01

    Full Text Available Background: Lumbar spine facet joints are arranged sagittally and mainly provide forward flexibility. Rotation of the lumbar vertebral body and coronal plane deformity may influence the function of lumbar forward flexibility. We hypothesize that the more advanced axial and coronal plane deformity could cause more limitation on forward flexibility in patients with idiopathic scoliosis. Methods: Between January 2011 and August 2011, 85 patients with adolescent idiopathic scoliosis were enrolled in this study. The proximal thoracic, major thoracic, thoracolumbar/lumbar (TL/L, and lumbar (L1/L5 curves were measured by Cobb's method. Lumbar apical rotation was graded using the Nash-Moe score. Lumbar forward flexibility was measured using the sit and reach (S and R test. Statistical analysis was performed using one-way analysis of variance (ANOVA, Spearman's and Pearson's correlation coefficients. Results: The mean age was 16.1 ± 2.84 years. The mean proximal thoracic, major thoracic, TL/L, and L1/L5 curves were 17.61° ± 8.92, 25.56° ± 11.61, 26.09° ± 8.6, and 15.10° ± 7.85, respectively. The mean S and R measurement was 25.56 ± 12.33 cm. The magnitude of the TL/L and L1/L5 curves was statistically positively related to vertebral rotation (rs = 0.580 and 0.649, respectively. The correlation between the S and R test and both the TL/L and L1/L5 curves was negative (rp = –0.371 and –0.595, respectively. Besides, the S and R test also demonstrated a significant negative relationship with vertebral rotation (rs = –0.768. Conclusion: In patients with idiopathic scoliosis, spinal deformity can diminish lumbar forward flexibility. Higher lumbar curvature and rotation lead to greater restriction of lumbar flexion.

    To gain insight into the pathophysiology of equine lumbar vertebral fractures in racehorses. To characterise equine lumbar vertebral fractures in California racehorses. Retrospective case series and prospective case-control study. Racehorse post mortem reports and jockey injury reports were retrospectively reviewed. Vertebral specimens from 6 racehorses affected with lumbar vertebral fractures and 4 control racehorses subjected to euthanasia for nonspinal fracture were assessed using visual, radiographic, computed tomography and histological examinations. Lumbar vertebral fractures occurred in 38 Quarter Horse and 29 Thoroughbred racehorses over a 22 year period, primarily involving the 5th and/or 6th lumbar vertebrae (L5-L6; 87% of Quarter Horses and 48% of Thoroughbreds). Lumbar vertebral fractures were the third most common musculoskeletal cause of death in Quarter Horses and frequently involved a jockey injury. Lumbar vertebral specimens contained anatomical variations in the number of vertebrae, dorsal spinous processes and intertransverse articulations. Lumbar vertebral fractures examined in 6 racehorse specimens (5 Quarter Horses and one Thoroughbred) coursed obliquely in a cranioventral to caudodorsal direction across the adjacent L5-L6 vertebral endplates and intervertebral disc, although one case involved only one endplate. All cases had evidence of abnormalities on the ventral aspect of the vertebral bodies consistent with pre-existing, maladaptive pathology. Lumbar vertebral fractures occur in racehorses with pre-existing pathology at the L5-L6 vertebral junction that is likely predisposes horses to catastrophic fracture. Knowledge of these findings should encourage assessment of the lumbar vertebrae, therefore increasing detection of mild vertebral injuries and preventing catastrophic racehorse and associated jockey injuries. © 2014 EVJ Ltd.

    Full Text Available The modern categorization defines the different forms of lumbar part spine stenosis, coming from anatomical and pathological of the principle. One of the varieties is a central lumbar stenosis. Compression of medulla spinalis occurs due to reduction of sizes of the spine central cannel caused either by osseous structure or softtissue of the spine canal. All softtissue components of the spinal canal can form stenos including defeat of intervertebral disk (the hernia of the disk. This work studies efficiency of Xray (at 33 patients and MRI (at 92 patients methods in diagnostics of the hernia of the disk that participates in forming lumbar part spine stenosis.

    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.

    Full Text Available Early diagnosis of meningitis and encephalitis and prompt initiation of appropriate therapy is vital and any delay will lead to high mortality and serious and permanent morbidity. The main purpose of this study was to evaluate the management of 220 patients with suspected central nervous system (CNS infections (meningitis and encephalitis to determine the percentage of patients’ suspected CNS infection undergo lumbar puncture in acceptable time (in accordance with conventional algorithms. In this descriptive study, patients with suspected CNS infections admitted to Bu-Ali and Qods hospitals, in the period July 2013 to December 2015 were studied. Information of 220 patients was collected. Continuous variables were summarized as means ± standard deviation and categorical variables as frequencies and percentages. Lumbar puncture (LP in patients was delayed in 200 cases (91%. Most common causes of delay in performing LP were prolongation of the process of determining patient needs to puncture, satisfying patients, CT scan delay and the delay in allowing LP by neurologist. In this study, delaying LP rate was higher than other studies. It seems certain pattern in assistants’ visits for counseling. CT requests and neurologic consultation before LP performed for all adult patients.

    2017-09-01

    Conclusion: Literature review of adults TCS associated with lumbar spinal degenerative disease as lumbar canal stenosis or disc herniation, is reported. Moderate entity of traction of spinal cord may remain asymptomatic in childhood and may result in delayed neurological deficits in adult life. The stretching of conus medullaris and spinal nerves of cauda equina, reduces regional blood flow and causes neural death and fibrous tissue replacement. Sudden or progressive onset of paraparesis with spastic gait, bladder dysfunction and acute low back pain in patient with history of spinal dysraphism must be considered as possible lumbar spinal cord compression caused by low lying cord related to TCS. Surgical decompression should be performed as early as possible to ensure neurological recovery. XLIF approach seems to be safe and fast and represent an excellent surgical option to obtain spinal cord indirect decompression and lumbar interbody fusion.

    Full Text Available Compression or irritation of the sciatic nerve and its branches, the common fibular and tibial nerves, causes sciatica which is a common syndrome characterized most often by radiating pain from the lower back down the legs and also manifesting as sensory and motor deficits. Sciatica is a common presentation of lumbosacral disc prolapse and degenerative disease of the lumbar spine in ambulatory settings. Schwannomas rarely cause sciatica; hence, it is seldom considered in evaluation of a patient with radiculopathy. Our patient presented with lumbar radiculopathy, mild degenerative changes on lumbar magnetic resonance imaging (MRI scan, and failed conservative treatment. Myelopathy was confirmed with electromyogram (EMG. Thoracolumbar spine MRI revealed the schwannoma in the thoracic region. He recovered neurologic function after tumor excision. This case highlights the diagnostic challenge that may arise in evaluating a patient with lumbar radiculopathy, negative lumbosacral spine imaging, and failure of conservative therapy.

    Spontaneous acute subarachnoid hemorrhage (SAH) from lumbar ependymoma in children is rare. We report a case of a14-year-old boy who developed sudden radicular low back pain while playing baseball. He was initially managed conservatively in a local hospital for suspected lumbar disc herniation, but later developed meningeal symptoms and fever before being referred to our hospital. There he underwent a diagnostic lumbar puncture in the emergency room; his cerebrospinal fluid suggested an SAH. Physical examination showed meningeal signs and cauda equina features. Cerebrospinal fluid analysis was negative for bacterial meningitis. Lumbar magnetic resonance imaging revealed a mass characterized as a hemorrhagic lesion. The patient had an emergent evacuation of the mass via the posterior approach. Postoperatively, his symptoms resolved completely. The histological diagnosis was, surprisingly, an ependymoma (WHO grade II). This case is particularly interesting because of its rarity in children, and its pattern of presentation. Though bacterial or viral meningitis is the most frequent cause of meningeal features in children, SAH from a hemorrhagic spinal tumor should be considered. Ultimately, a high index of suspicion is needed for prompt diagnosis.

    1996-12-01

    Lumbar hernias are very rare and no more than 300 are reported in literature. They can be classified as congenital and acquired. The latter are in turn subdivided into primary and secondary. Secondary traumatic lumbar hernias account for 25% of all cases. The site of the formation of this hernia is mainly Grynfelt's triangle and, to a lesser extent, Petit's triangle. Traumatic lumbar hernia have very moderate symptoms and may be corrected surgically relatively easily, in particular with the use of Marlex nets. Recidivations can be easily identified owing to the lack of aponeurotic support structures in this anatomic site. Owing to their traumatic etiopathogenesis these hernias are of particular medicolegal importance for the purposes of indemnity. The case reported refers to a 46-years-old man involved in a road accident who sustained an injury caused by the explosion of hollow viscera in the abdomen and the subsequent onset of a hernia swelling through Petit's triangle in the right lumbar region. Owing to the width of the breach, plastic surgery was carried out using a Marlex graft. A large recidivation was observed around one year later.

    Full Text Available Background: thoraco-lumbar fractures may affect people at any moment of their lives, especially at their most fruitful and useful stage. Its correct diagnosis and treatment may directly influence in the posterior evolution of the patients. Objectives: to evaluate the results of the surgical treatment in thoraco-lumbar region fractures. Methods: a descriptive retrospective correlational study of series cases which included 54 patients attended due to thoraco-lumbar region fractures in the University Hospital “Dr. Gustavo Aldereguía Lima” in Cienfuegos city, Cuba from January 1999 to June 2007. Age, sex, etiology of the fracture, type and level of the fractures, associated diseases, surgical techniques used for, pre and post operatory neurological damage, usage of metilprednisolone, complications and final results were the variables taken into consideration in this study. Results: most of the patients belonged to male sex under the age of 45. The totality of the cases had type IV fracture, and a great part of them had Denis type II fracture having surgical treatment. The causes of the lesions were traffic accidents, working accidents and height falls. The most useful surgical techniques were posterior decompression, instrumentation and fusion. Surgery improved the neurological damage in almost half of sick patients with this condition. Complications were minimum and rupture of the implant was predominant. Conclusion: surgical treatment in thoraco-lumbar region fractures had satisfactory results in our milieu.

    Full Text Available Abstract Background Most lumbar artificial discs are still composed of stainless steel alloys, which prevents adequate postoperative diagnostic imaging of the operated region when using magnetic resonance imaging (MRI. Thus patients with postoperative radicular symptoms or claudication after stainless steel implants often require alternative diagnostic procedures. Methods Possible complications of lumbar total disc replacement (TDR are reviewed from the available literature and imaging recommendations given with regard to implant type. Two illustrative cases are presented in figures. Results Access-related complications, infections, implant wear, loosening or fracture, polyethylene inlay dislodgement, facet joint hypertrophy, central stenosis, and ankylosis of the operated segment can be visualised both in titanium and stainless steel implants, but require different imaging modalities due to magnetic artifacts in MRI. Conclusion Alternative radiographic procedures should be considered when evaluating patients following TDR. Postoperative complications following lumbar TDR including spinal stenosis causing radiculopathy and implant loosening can be visualised by myelography and radionucleotide techniques as an adjunct to plain film radiographs. Even in the presence of massive stainless steel TDR implants lumbar radicular stenosis and implant loosening can be visualised if myelography and radionuclide techniques are applied.

    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.

    Full Text Available Disc cysts are uncommon intraspinal cystic lesions located in the ventrolateral epidural space. They communicate with the nucleus pulposus of the intervertebral disc and cause symptoms by radicular compression. We report a unique case of lumbar disc cyst that was associated with disc herniation and contralateral radiculopathy. A 22 year old male presented with one month history of back-ache radiating to the left leg. Magnetic Resonance Imaging (MRI showed L3-L4 disc herniation with annular tear and cystic lesion in the extradural space anterior to the thecal sac on right side, which increased in size over a period of 3 weeks. L3 laminectomy and bilateral discectomy and cyst excision was done with partial improvement of patients symptoms.

    A series of lumbar myelographies -- 105 in 98 patients - was carried out with water-soluble Metrizamid (Amipaque R) in a concentration of 170 mg I/ml and showed side-effects in 32% and a quality of contrast similar to that of other water-soluble contrast media used before. The side effects were mild, of short duration and needed no treatment. There were no epileptic fits, tonic or clonic carried out 1 - 12 months later showed no signs of arachnoiditis. Dangers of more serious complications appeared to increase, the higher the level of injection into the spinal canal. A short survey of contrast media used in myelography and earlier experience of experimental or clinical side effects caused by Medtrizamid in myelography follows.

  14. Lumbar degenerative spinal deformity: Surgical options of PLIF, TLIF and MI-TLIF

    2010-01-01

    Full Text Available Degenerative disease of the lumbar spine is common in ageing populations. It causes disturbing back pain, radicular symptoms and lowers the quality of life. We will focus our discussion on the surgical options of posterior lumbar interbody fusion (PLIF and transforaminal lumbar interbody fusion (TLIF and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF for lumbar degenerative spinal deformities, which include symptomatic spondylolisthesis and degenerative scoliosis. Through a description of each procedure, we hope to illustrate the potential benefits of TLIF over PLIF. In a retrospective study of 53 ALIF/PLIF patients and 111 TLIF patients we found reduced risk of vessel and nerve injury in TLIF patients due to less exposure of these structures, shortened operative time and reduced intra-operative bleeding. These advantages could be translated to shortened hospital stay, faster recovery period and earlier return to work. The disadvantages of TLIF such as incomplete intervertebral disc and vertebral end-plate removal and potential occult injury to exiting nerve root when under experienced hands are rare. Hence TLIF remains the mainstay of treatment in degenerative deformities of the lumbar spine. However, TLIF being a unilateral transforaminal approach, is unable to decompress the opposite nerve root. This may require contralateral laminotomy, which is a fairly simple procedure.The use of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF to treat degenerative lumbar spinal deformity is still in its early stages. Although the initial results appear promising, it remains a difficult operative procedure to master with a steep learning curve. In a recent study comparing 29 MI-TLIF patients and 29 open TLIF, MI-TLIF was associated with longer operative time, less blood loss, shorter hospital stay, with no difference in SF-36 scores at six months and two years. Whether it can replace traditional TLIF as the surgery of

    OBJECTIVE Lumbar epidural steroid injections (LESIs) are performed for both diagnostic and therapeutic purposes for a variety of indications, including low-back pain, the leading cause of disability and expense due to work-related conditions in the US. The steroid agent used in epidural injections is reported to relieve nerve root inflammation, local ischemia, and resultant pain, but the injection may also have an adverse impact on spinal surgery performed thereafter. In particular, the possibility that preoperative epidural injections may increase the risk of surgical site infection after lumbar spinal fusion has been reported but has not been studied in detail. The goal of the present study was to use a large national insurance database to analyze the association of preoperative LESIs with surgical site infection after lumbar spinal fusion. METHODS A nationwide insurance database of patient records was used for this retrospective analysis. Current Procedural Terminology codes were used to query the database for patients who had undergone LESI and 1- or 2-level lumbar posterior spinal fusion procedures. The rate of postoperative infection after 1- or 2-level posterior spinal fusion was analyzed. These study patients were then divided into 3 separate cohorts: 1) lumbar spinal fusion performed within 1 month after LESI, 2) fusion performed between 1 and 3 months after LESI, and 3) fusion performed between 3 and 6 months after LESI. The study patients were compared with a control cohort of patients who underwent lumbar fusion without previous LESI. RESULTS The overall 3-month infection rate after lumbar spinal fusion procedure was 1.6% (1411 of 88,540 patients). The infection risk increased in patients who received LESI within 1 month (OR 2.6, p fusion more than 3 months after LESI. CONCLUSIONS Lumbar spinal fusion performed within 3 months after LESI may be associated with an increased rate of postoperative infection. This association was not found when lumbar

    Observational study. To correlate lumbar lordosis and lumbar core strength in information technology (IT) professionals. IT professionals have to work for long hours in a sitting position, which can affect lumbar lordosis and lumbar core strength. Flexicurve was used to assess the lumbar lordosis, and pressure biofeedback was used to assess the lumbar core strength in the IT professionals. All subjects, both male and female, with and without complaint of low back pain and working for two or more years were included, and subjects with a history of spinal surgery or spinal deformity were excluded from the study. Analysis was done using Pearson's correlation. For the IT workers, no correlation was seen between lumbar lordosis and lumbar core strength (r=-0.04); however, a weak negative correlation was seen in IT people who complained of pain (r=-0.12), while there was no correlation of lumbar lordosis and lumbar core in IT people who had no complains of pain (r=0.007). The study shows that there is no correlation of lumbar lordosis and lumbar core strength in IT professionals, but a weak negative correlation was seen in IT people who complained of pain.

    Congenital lumbar hernias are rare malformations caused by defects in the development of the posterior abdominal wall. A known association exists with lumbocostovertebral syndrome; however other associated anomalies, including one case with arthrogryposis, have been previously reported. We present an infant girl with bilateral congenital lumbar hernias, multiple joint contractures, decreased muscle bulk and symptoms of malignant hyperthermia. Molecular testing revealed an R4861C mutation in the ryanodine receptor 1 (RYR1) gene, known to be associated with central core disease. This is the first reported case of the co-occurrence of congenital lumbar hernias and central core disease. We hypothesize that ryanodine receptor 1 mutations may interrupt muscle differentiation and development. Further, this case suggests an expansion of the ryanodine receptor 1-related myopathy phenotype to include congenital lumbar hernias.

    In patients with lower back and leg pain, lumbar foraminal stenosis (LFS) is one of the most important pathologies, especially for predominant radicular symptoms. LFS pathology can develop as a result of progressing spinal degeneration and is characterized by exacerbation with foraminal narrowing caused by lumbar extension (Kemp's sign). However, there is a lack of critical clinical findings for LFS pathology. Therefore, patients with robust and persistent leg pain, which is exacerbated by lumbar extension, should be suspected of LFS. Radiological diagnosis is performed using multiple radiological modalities, such as magnetic resonance imaging, including plain examination and novel protocols such as diffusion tensor imaging, as well as dynamic X-ray, and computed tomography. Electrophysiological testing can also aid diagnosis. Treatment options include both conservative and surgical approaches. Conservative treatment includes medication, rehabilitation, and spinal nerve block. Surgery should be considered when the pathology is refractory to conservative treatment and requires direct decompression of the exiting nerve root, including the dorsal root ganglia. In cases with decreased intervertebral height and/or instability, fusion surgery should also be considered. Recent advancements in minimally invasive lumbar lateral interbody fusion procedures enable effective and less invasive foraminal enlargement compared with traditional fusion surgeries such as transforaminal lumbar interbody fusion. The lumbosacral junction can cause L5 radiculopathy with greater incidence than other lumbar levels as a result of anatomical and epidemiological factors, which should be better addressed when treating clinical lower back pain.

    Minimally invasive unilateral pedicle screw fixation for the treatment of degenerative lumbar diseases has won the support of many surgeons. However, few data are available regarding clinical research on unilateral pedicle screw fixation associated with minimally invasive techniques for the treatment of lumbar spinal diseases. The purpose of this study was to evaluate clinical outcomes in a selected series of patients with lumbar degenerative diseases treated with minimally invasive unilateral vs classic bilateral pedicle screw fixation and lumbar interbody fusion. Patients in the unilateral group (n=43) underwent minimally invasive unilateral pedicle screw fixation with the Quadrant system (Medtronic, Memphis, Tennessee). The bilateral group (n=42) underwent bilateral instrumentation via the classic approach. Visual analog scale pain scores, Oswestry Disability Index scores, fusion rate, operative time, blood loss, and complications were analyzed. Mean operative time was 75 minutes in the unilateral group and 95 minutes in the bilateral group. Mean blood loss was 220 mL in the unilateral group and 450 mL in the bilateral group. Mean postoperative visual analog scale pain score was 3.10±0.16 in the unilateral group and 3.30±1.10 in the bilateral group. Mean postoperative Oswestry Disability Index score was 15.67±2.3 in the unilateral group and 14.93±2.6 in the bilateral group. Successful fusion was achieved in 92.34% of patients in the unilateral group and 93.56% of patients in the bilateral group. Minimally invasive unilateral pedicle screw fixation is an effective and reliable option for the surgical treatment of lumbar degenerative disease. It causes less blood loss, requires less operative time, and has a fusion rate comparable with that of conventional bilateral fixation. Copyright 2013, SLACK Incorporated.

    Full Text Available Laxmaiah Manchikanti,1,2 Kimberly A Cash,1 Carla D McManus,1 Vidyasagar Pampati,1 Ramsin Benyamin3,41Pain Management Center of Paducah, Paducah, KY; 2University of Louisville, Louisville, KY; 3Millennium Pain Center, Bloomington, IL; 4University of Illinois, Urbana-Champaign, IL, USAAbstract: Among the multiple causes of chronic low back pain, axial and discogenic pain are common. 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. For those with chronic function-limiting low back pain refractory to conservative management

    To examine whether lumbar disc herniation with massive extrusion and/or segmental instability can be an indicator for spinal fusion or not, by comparing the outcome of posterior lumbar interbody fusion (PLIF) and discectomy alone. One hundred seventy-four patients with PLIF and 177 patients with discectomy were retrospectively analyzed. We hypothesized two criteria for fusion: massive herniation and segmental instability. The patients were divided into four groups according to our original criteria: group F-F (n = 96) consisted of the patients who fulfilled the criteria for fusion and underwent PLIF; group nF-F (n = 78) consisted of those who did not fulfill the criteria but had PLIF; group F-nF (n = 30) consisted of those who fulfilled the criteria but underwent discectomy; group nF-nF (n = 147) comprised those who did not fulfill the criteria and underwent discectomy. Each patient was evaluated clinically and radiologically at 5 years after operation. Groups F-F and nF-F had significantly superior results on low back pain compared with group F-nF (F-F vs F-nF, P < 0.05; nF-F vs F-nF, P < 0.01). The frequency of additional operation at the involved level was significantly higher in group F-nF (10.0%) than in group F-F (2.0%) (P < 0.05). Postoperative instability of the adjacent segment developed in 15 cases (8.6%) in groups F-F and nF-F and in 3 cases (1.7%) in groups F-nF and nF-nF (P < 0.01). Lumbar disc herniation with massive herniation or segmental instability can be well treated with PLIF.

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

  6. Neuromuscular disorders associated with static lumbar flexion: a feline model.

    2002-04-01

    Static flexion of the lumbar spine with constant load applied to the viscoelastic structures for 20 minutes and for 50 minutes resulted in development of spasms and inhibition in the multifidus muscles (e.g., deep erector spinae) and in creep of the supraspinous ligament in the feline model. The development of spasms and inhibition was not dependent on load magnitude. It is suggested that occupational and sports activities which require prolonged static lumbar flexion within the physiological range can cause a "sprain"-like injury to the ligaments, which in turn reflexively induce spasms and inhibition in some erector spinae muscles. Such disorder may take a long time to recover, in the order of days to weeks, depending on the level of creep developed in the tissues.

    MARCELO SIMONI SIMÕES

    Full Text Available ABSTRACT Objective: To evaluate the impact of a minimally invasive lumbar one-level fixation on trunk mobility and quality of life compared with the preoperative condition in 26 consecutive patients. Methods: The following data were collected preoperatively and postoperatively for the statistical analysis: maximal trunk extension and flexion angles, Visual Analog Scale of pain and Oswestry Disability Index scores. Results: There was improvement in all variables. Statistical significance was observed in trunk extension, pain, and Oswestry Disability Index. Although mobility in trunk flexion was higher in average values after surgery, this difference was not statistically demonstrated. Conclusion: Minimally invasive one-level lumbar fixation does not cause reduction of trunk flexibility in comparison to the mobility before surgery.

    Background: Postoperative remote cerebellar hemorrhage (RCH) as a complication of lumbar spinal surgery is an increasingly recognized clinical entity. The aim of this study was to determine the incidence of RCH after lumbar spinal surgery and to describe diagnostic imaging findings of RCH. Methods: Between October 1996 and March 2007, 2444 patients who had undergone lumbar spinal surgery were included in the study. Thirty-seven of 2444 patients were scanned by CT or MRI due to neurologic symptoms within the first 7 days of postoperative period. The data of all the patients were studied with regard to the following variables: incidence of RCH after lumbar spinal surgery, gender and age, coagulation parameters, history of previous arterial hypertension, and position of lumbar spinal surgery. Results: The retrospective study led to the identification of two patients who had RCH after lumbar spinal surgery. Of 37 patients who had neurologic symptoms, 29 patients were women and 8 patients were men. CT and MRI showed subarachnoid hemorrhage in the folia of bilateral cerebellar hemispheres in both patients with RCH. The incidence of RCH was 0.08% among patients who underwent lumbar spinal surgery. Conclusion: RCH is a rare complication of lumbar spinal surgery, self-limiting phenomenon that should not be mistaken for more ominous pathologic findings such as hemorrhagic infarction. This type of bleeding is thought to occur secondary to venous infarction, but the exact pathogenetic mechanism is unknown. CT or MRI allowed immediate diagnosis of this complication and guided conservative management.

    Conclusion: A surgeon may encounter a primary lumbar hernia perhaps once in his lifetime making it an interesting surgical challenge. Sound anatomical knowledge and adequate imaging are indispensable. Inspite of advances in minimally invasive surgery, it cannot be universally applied to patients with lumbar hernia and management requires a more tailored approach.

    Lumbar facet cysts are a benign, degenerative, and fairly uncommon cause for lumbar radiculopathy. The standard surgical treatment for lumbar facet cysts often requires a laminectomy and medial facetectomy which can further destabilize a pathological motion segment. The authors present here a novel technique for transpedicular endoscopic access to the pathology that obviates the need to violate the lamina or facet. Two patient cases are described where the lumbar 4-5 facet cysts arise medial to the pedicle. Percutaneous access to the cysts was established by drilling through the adjacent pedicle creating a 7-mm corridor to establish access for the endoscopic tubular retractor and the working channel endoscope. Straight and bendable forceps were used to remove the cysts under direct visualization. Following surgery, the patients' symptoms showed immediate regression with complete relief of one patient's foot drop by 6 months. Transpedicular endoscopic access is described as novel minimally invasive surgical option in the awake patient for lumbar facet cysts adjacent to the Lumbar 4 or 5 pedicle.

    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.

    Lumbar osteoid osteoma has a low incidence, which could easily lead to scoliosis. Scoliosis secondary to lumbar osteoid osteoma could be easily misdiagnosed when patients do not complain of obvious symptoms. We reported a case of a 9-year-old boy with back deformity that was firstly diagnosed with scoliosis at the local hospital. After prescribed with orthosis, the patient experienced aggravating pain that could not be relieved with painkillers. After he admitted to our hospital for further medical advice, he was prescribed to complete radiological examinations. Considering his radiological examination results and his medical history, correct diagnosis of lumbar osteoid osteoma was made. Surgical intervention of posterior lesion resection was conducted after diagnosis. Intra-operative frozen pathology indicated features of osteoid osteoma. As the lesion involved inferior articular process of L5, which could cause lumbar instability after lesion resection, internal fixation was conducted at L4-S1 segment, and posterolateral bone fusion was also conducted at L5-S1 segment. Three months after operation, the patient showed marked improvement of scoliosis deformity and great relief of lumbar pain. Although spine osteoid osteoma is clinically rare, it shall not be overlooked when young patients present with scoliosis first. Radiological results including computed tomography and magnetic resonance imaging shall be taken carefully as reference when making diagnosis. Surgical intervention of lesion resection could well improve scoliosis and relieve lumbar pain.

    Background Visceral pain is a common cause for seeking medical attention.Afferent fibers innervating viscera project to the central nervous system via sympathetic nerves.The lumbar sympathetic nerve trunk lies in front of the lumbar spine.Thus,it is possible for patients to suffer visceral pain originating from sympathetic nerve irritation induced by anterior herniation of the lumbar disc.This study aimed to evaluate lumbar discogenic visceral pain and its treatment.Methods Twelve consecutive patients with a median age of 56.4 years were enrolled for investigation between June 2012 and December 2012.These patients suffered from long-term abdominal pain unresponsive to current treatment options.Apart from obvious anterior herniation of the lumbar discs and high signal intensity anterior to the herniated disc on magnetic resonance imaging,no significant pathology was noted on gastroscopy,vascular ultrasound,or abdominal computed tomography (CT).To prove that their visceral pain originated from the anteriorly protruding disc,we evaluated whether pain was relieved by sympathetic block at the level of the anteriorly protruding disc.If the block was effective,CT-guided continuous lumbar sympathetic nerve block was finally performed.Results All patients were positive for pain relief by sympathetic block.Furthermore,the average Visual Analog Scale of visceral pain significantly improved after treatment in all patients (P <0.05).Up to 11/12 patients had satisfactory pain relief at 1 week after discharge,8/12 at 4 weeks,7/12 at 8 weeks,6/12 at 12 weeks,and 5/12 at 24 weeks.Conclusions It is important to consider the possibility of discogenic visceral pain secondary to anterior herniation of the lumbar disc when forming a differential diagnosis for seemingly idiopathic abdominal pain.Continuous lumbar sympathetic nerve block is an effective and safe therapy for patients with discogenic visceral pain.

    Sitting has been identified as a cause of mechanical low back pain. The purpose of this study was to use plain film x-rays to measure lumbar spine and pelvic posture differences between standing and sitting. Eight male subjects were radiographed standing and sitting in an automobile seat. Measures of lumbar lordosis, intervertebral disk angles, lumbosacral angle, lumbosacral lordosis, and sacral tilt were completed. One-way analysis of variance (alpha = .05) was conducted on the variables stated above. A Bland-Altman analysis was conducted to assess agreement and repeatability of the lumbar lordosis angle using 2 raters. Lumbar lordosis values in standing (average, 63 degrees +/- 15 degrees ) and sacral inclination (average, 43 degrees +/- 10 degrees ) decreased by 43 degrees and 44 degrees , respectively, in sitting. Intervertebral joint angles in sitting underwent substantial flexion (L1/L2-5 degrees [+/-3 degrees ], L2/L3-7 degrees [+/-3 degrees ], L3/L4-8 degrees [+/-3 degrees ], L4/L5-13 degrees [+/-3 degrees ], and L5/S1-4 degrees [+/-10 degrees ]). Measures of lumbar lordosis; intervertebral disk angles between L2/L3, L3/L4, and L4/L5; lumbosacral lordosis; lumbosacral angle; and sacral tilt were significantly decreased between standing and sitting (P posture should be investigated because they may play a role in preventing injury and low back pain.

    Flat-back syndrome is one of the main causes of surgical failure after lumbar fusion and can lead to a revision surgery to correct it. Three-column pedicle subtraction osteotomy is an efficient technique to restore lumbar lordosis (LL) for fixed sagittal malalignment. The fusion mass stemming from the past surgeries makes the procedure demanding as most anatomical landmarks are missing. This review article will focus on the correction of this lack of LL through the fusion mass. We will successively review the preoperative management, the surgical specificities, and various types of clinical cases that can be encountered in flat-back syndromes. PSO in the fixed fusion mass is technically demanding. Preoperative CT-scan and preoperative navigation allow us to push the limits when anatomical landmarks disappear. Bleeding and neurologic are the two major complications feared by the surgeon. The best way to avoid these revision surgeries is to restore a proper lumbar lordosis at the time of initial surgery by considering lumbo-pelvic indexes.

    Full Text Available Posterior lumbar interbody fusion using cages, titanium rods, and pedicle screws is considered today as the gold standard of surgical treatment of lumbar degenerative disease and has produced satisfying long-term fusion rates. However this rigid material could change the physiological distribution of load at the instrumental and adjacent segments, a main cause of implant failure and adjacent segment disease, responsible for a high rate of further surgery in the following years. More recently, semirigid instrumentation systems using rods made of polyetheretherketone (PEEK have been introduced. This clinical study of 21 patients focuses on the clinical and radiological outcomes of patients with lumbar degenerative disease treated with Initial VEOS PEEK®-Optima system (Innov’Spine, France composed of rods made from PEEK-OPTIMA® polymer (Invibio Biomaterial Solutions, UK without arthrodesis. With an average follow-up of 2 years and half, the chances of reoperation were significantly reduced (4.8%, quality of life was improved (ODI = 16%, and the adjacent disc was preserved in more than 70% of cases. Based on these results, combined with the biomechanical and clinical data already published, PEEK rods systems can be considered as a safe and effective alternative solution to rigid ones.

    To evaluate the inflammatory involvement of lumbar interspinous bursae in patients with polymyalgia rheumatica (PMR) using magnetic resonance imaging (MRI). Ten consecutive, untreated new patients with PMR and pain in the shoulder and pelvic girdles were investigated. Seven patients with spondyloarthritis (4 with psoriatic spondyloarthrits, one with entheropatic spondyloarthritis, and 2 with ankylosing spondylitis) as well as 2 patients with spinal osteoarthritis and 2 patients with rheumatoid arthritis with lumbar pain served as controls. MRI of lumbar spine was performed in all PMR patients and controls. Nine patients (5 PMR patients and 4 controls) also had MRI of the thoracic spine. MRI evidence of interspinous lumbar bursitis was found in 9/10 patients with PMR and in 5/11 controls. A moderate to marked (grade ≥2 on a semiquantitative 0-3 scale) lumbar bursitis occurred significantly more frequently in patients with PMR than in control patients (60% vs. 9%, p=0.020). In most of the patients and controls lumbar bursitis was found at the L3-L5 interspaces. Only 2 patients had bursitis at a different level (one patient had widespread lumbar bursitis, and one control at L2-L4). No interspinous bursitis was demonstrated by MRI of the thoracic spine in patients and controls. Inflammation of lumbar bursae may be responsible for the low back pain reported by patients with PMR. The prominent inflammatory involvement of bursae including those of the lumbar spine supports the hypothesis that PMR may be a disorder affecting predominantly extra-articular synovial structures.

    Magnetic resonance imaging is established as the technique of choice for assessment of degenerative disorders of the lumbar spine. However, it is routinely performed with the patient supine and the hips and knees flexed. The absence of axial loading and lumbar extension results in a maximization of spinal canal dimensions, which may in some cases, result in failure to demonstrate nerve root compression. Attempts have been made to image the lumbar spine in a more physiological state, either by imaging with flexion-extension, in the erect position or by using axial loading. This article reviews the literature relating to the above techniques.

    Full Text Available Lumbar spinal stenosis is a common condition in elderly patients and may lead to progressive back and leg pain, muscular weakness, sensory disturbance, and/or problems with ambulation. Multiple studies suggest that surgical decompression is an effective therapy for patients with symptomatic lumbar stenosis. Although traditional lumbar decompression is a time-honored procedure, minimally invasive procedures are now available which can achieve the goals of decompression with less bleeding, smaller incisions, and quicker patient recovery. This paper will review the technique of performing ipsilateral and bilateral decompressions using a tubular retractor system and microscope.

    Although they are freqqently described in the literature, lumbar synovial cysts are a relative uncommon cause of low back and radicular leg pain. To evaluate the treatment and surgical outcomes of the lumbar synovial cysts operated on in our hospital during a 5 year period. A retrospective study was conducted on patients surgically treated in our department from August 2009 to September 2014, using a visual analogue scale for the clinical follow-up in the first year after surgery. After the surgical treatment (surgical removal of the synovial cyst with or without instrumented arthrodesis with transpedicular screws) of 10 patients (5 female and 5 male) with a mean age of 70.2 years (range 50-80), the clinical outcome was satisfactory in 80% of the patients, with the resolving of their symptoms. Lumbar synovial cysts have to be considered in the differential diagnosis in patients with low back and radicular leg pain. The majority of the patients are in their sixties and have lumbar degenerative spondylopathy. Nowadays, surgical resection of the lumbar synovial cysts and spinal fusion are the recommended treatment, because it is thought that the increased movement of the spine is one to the causes of the cyst formation. More studies are still needed, hence the relevance of this article. Copyright © 2016 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.

    Approximately 50% of a sample population will develop prolonged standing induced low back pain. The cause of this pain may be due to their lumbar spine posture. The purpose of this study was to investigate differences in lumbar posture between 17 participants categorized as a pain or non-pain developers during level ground standing. A secondary purpose was to evaluate the influence of two standing aids (an elevated surface to act as a foot rest and declined sloped surface) on lumbopelvic posture. Four sagittal plane radiographs were taken: a normal standing position on level ground, when using an elevated foot rest, using a declined sloped surface, and maximum lumbar spine extension as a reference posture. Lumbosacral lordosis, total lumbar lordosis, and L1/L2 and L5/S1 intervertebral joint angles were measured on each radiograph. There was a significant difference between the lumbosacral lordosis angle and L5/S1 angles in upright versus maximum extension; however, this was independent of pain group. The elevated surface was most effective at causing lumbosacral spine flexion. Potentially successful postures for eliminating low back pain during prolonged standing mainly influence the lower lumbar lordosis. Future work should assess the influence of hip posture on low back pain development during standing. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Yue, James J; Garcia, Rolando; Miller, Larry E

    2016-01-01

    Degeneration of the lumbar intervertebral discs is a leading cause of chronic low back pain in adults. Treatment options for patients with chronic lumbar discogenic pain unresponsive to conservative management include total disc replacement (TDR) or lumbar fusion. Until recently, only two lumbar TDRs had been approved by the US Food and Drug Administration - the Charité Artificial Disc in 2004 and the ProDisc-L Total Disc Replacement in 2006. In June 2015, a next-generation lumbar TDR received Food and Drug Administration approval - the activL(®) Artificial Disc (Aesculap Implant Systems). Compared to previous-generation lumbar TDRs, the activL(®) Artificial Disc incorporates specific design enhancements that result in a more precise anatomical match and allow a range of motion that better mimics the healthy spine. The results of mechanical and clinical studies demonstrate that the activL(®) Artificial Disc results in improved mechanical and clinical outcomes versus earlier-generation artificial discs and compares favorably to lumbar fusion. The purpose of this report is to describe the activL(®) Artificial Disc including implant characteristics, intended use, surgical technique, postoperative care, mechanical testing, and clinical experience to date.

    Lumbar epidural varices are rare and usually mimick lumbar disc herniations. Back pain and radiculopathy are the main symptoms of lumbar epidural varices. Perineural cysts are radiologically different lesions and should not be confused with epidural varix. A 36-year-old male patient presented to us with right leg pain. The magnetic resonance imaging revealed a cystic lesion at S1 level that was compressing the right root, and was interpreted as a perineural cyst. The patient underwent surgery via right L5 and S1 hemilaminectomy, and the lesion was coagulated and removed. The histopathological diagnosis was epidural varix. The patient was clinically improved and the follow-up magnetic resonance imaging showed the absence of the lesion. Lumbar epidural varix should be kept in mind in the differential diagnosis of the cystic lesions which compress the spinal roots. PMID:23741553

    We reported the 18 patients which underwent surgical exploration and reviewed these CT findings. Method All CT scans were obtained on Somatom II, high resolution CT scanner, with the patient in the supine position. A lateral localizer image (Topogram) was used to select the appropriate intervertebral disk space. The slice thickness was 4 mm. Results 1) CT findings in lumbar degenerative diseases include bony canal stenosis (central canal stenosis, narrowed lateral recess), soft tissue abnormalities (herniated nucleus pulposus, bulging annulus, hypertrophy and/or ossification of ligamentum flavum, no delineation of nerve root in lateral recess), and spinal instability (spondylolisthesis, vacuum phenomenon). 2) The above three factors contribute to narrowing of spinal canal. 3) No delineation of nerve root or soft tissue replacement of epidural fat in lateral recess suggests that the nerve root may be compressed by some factors. 4) Herniated nucleus pulposus may cause nerve root compression with or without canal stenosis. Conclusion This study revealed that the CT findings correlated closely with the surgical findings and the site of nerve root compression could be determined.

    The wide exposure required for a standard posterior lumbar interbody fusion (PLIF) can cause unnecessary trauma to the lumbar musculoligamentous complex. By combining existing microendoscopic, percutaneous instrumentation and interbody technologies, a novel, minimally invasive, percutaneous PLIF technique was developed to minimize such iatrogenic tissue injury (MIP-PLIF). The MIP-PLIF technique was validated in three cadaveric torsos with six motion segments decompressed and fused. Preoperative variables measured from imaging included interpedicular distance, pedicular height and width, interspinous distance, lordosis, intervertebral height, Cobb angle, and foraminal height and volume. Using the METRx and MD spinal access systems (Medtronic Sofamor Danek, Memphis, TN), bilateral laminotomies were performed using a hybrid of microsurgical and microendoscopic techniques. The intervertebral disc spaces were then distracted and prepared with the Tangent (Medtronic Sofamor Danek) interbody instruments. Either a 10 or 12 by 22 mm interbody graft was then placed. Using the Sextant (Medtronic Sofamor Danek) system, percutaneous pedicle screw-rod fixation of the motion segment was completed. We then applied MIP-PLIF in three patients. For segments with preoperative intervertebral/foraminal height loss, MIP-PLIF was effective in restoring both heights in all cases. The amount of improvement (9.7 to 38% disc height increase; 7.7 to 29.9% foraminal height increase) varied directly with the size of the graft used and the original degree of disc and foraminal height loss. Segmental lordosis improved by 29% on average. Graft and screw placement was accurate in the cadavers, except for a single Grade 1 screw violation of one pedicle. The average operative time was 3.5 hours per level. In our three clinical cases, the MIP-PLIF procedure required a mean of 5.4 hours, estimated blood loss was 185 ml, and inpatient stay was 2.8 days, with no intravenous narcotic use after 2 days in

    The posteroanterior view of the lumbar spine has important features including radiation protection and image quality; these have been studied by various investigators. Investigators have shown that sensitive tissues receive less radiation dosage in the posteroanterior view of the spine for scoliosis screening and intracranial tomography without altering the image quality. This paper emphasizes the importance of the radiation safety aspect of the posteroanterior view and shows the improvement in shape distortion in the lumbar vertebrae.

    Among the multiple causes of chronic low back pain, axial and discogenic pain are common. 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. For those with chronic function-limiting low back pain refractory to conservative management, it is concluded that lumbar interlaminar epidural injections of local anesthetic with or without steroids may be an effective modality for managing chronic axial or discogenic pain. This treatment appears to be effective for those who have had facet joints as well as sacroiliac joints eliminated as the pain source.

    Full Text Available To date no studies have been published on preoperative education forpatients who had lumbar surgery. The aim of this study was to determine if there is a demand for preoperative education for patients who had lumbar surgery for radiculopathy. A convenience sample of 47 patients who had lumbar surgery and a random sample of 141 physiotherapists involved in treating patients who had lumbar surgery completed a newly developed spinal surgery questionnaire. The data were analyzed using descriptiveand inferential statistical tests. Results showed that 100% of the patients and 99% of therapists view preoperative education to be an important component for lumbar surgery for radiculopathy. The most important factors identifiedfor inclusion in preoperative educational programs were reason for surgery, risks associated with surgery, limitations following surgery and more education regarding pain. The preferred method of education delivery was verbal one-on-one education. This study demonstrates that there is a demand for preoperative education for patients who had lumbar surgery.

    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.

    Full Text Available Juxtafacet cysts are an uncommon cause of radiculopathy. They occur most frequently in the lumbar region, and their distribution across the spine correlates with mobility. Haemorrhagic complications are rare and may occur in the absence of any provocation, although there is some association with anticoagulation and trauma. We present a case of acute radiculopathy due to an L5/S1 juxtafacet cyst with unprovoked haemorrhage which was found to extend into ligamentum flavum. The patient underwent uncomplicated microscope assisted decompression with excellent results. The demographics, presentation, aetiology, and management of juxtafacet cysts are discussed.

    Gas-containing (emphysematous) infections of the abdomen, pelvis, and extremities are well-known disease entities, which can potentially be life-threatening. They require aggressive medical and often surgical treatment. In the neurosurgical field, some cases of gas-containing brain abscess and subdural empyema have been reported. Sometimes they progress rapidly and even can cause fatal outcome. However, gas-containing spinal epidural abscess has been rarely reported and clinical course is unknown. We report on a case of rapidly progressive gas-containing lumbar spinal epidural abscess due to Enterococcus faecalis in a 72-year-old male patient with diabetes mellitus.

    Study Design Level 4 retrospective review. Purpose To compare the radiographic and clinical outcomes between posterior lumbar interbody fusion (PLIF) and lateral lumbar interbody fusion (LLIF) with posterior segmental spinal instrumentation (SSI) for degenerative lumbar spondylolisthesis. Overview of Literature Both PLIF and LLIF have been performed for degenerative spondylolisthesis with good results, but no study has directly compared these two techniques so far. Methods The electronic medical and radiographic records of 78 matched patients were analyzed. In one group, 39 patients underwent PLIF with SSI at 41 levels (L3-4/L4-5), while in the other group, 39 patients underwent the LLIF procedure at 48 levels (L3-4/L4-5). Radiological outcomes such as restoration of disc height and neuroforaminal height, segmental lumbar lordosis, total lumbar lordosis, incidence of endplate fracture, and subsidence were measured. Perioperative parameters were also recorded in each group. Clinical outcome in both groups was assessed by the short form-12, Oswestry disability index and visual analogue scale scores. The average follow-up period was 16.1 months in the LLIF group and 21 months in the PLIF group. Results The restoration of disc height, foraminal height, and segmental lumbar lordosis was significantly better in the LLIF group (p<0.001). The duration of the operation was similar in both groups, but the average blood loss was significantly lower in the LLIF group (p<0.001). However, clinical outcome scores were similar in both groups. Conclusions Safe, effective interbody fusion can be achieved at multiple levels with neuromonitoring by the lateral approach. LLIF is a viable treatment option in patients with new onset symptoms due to degenerative spondylolisthesis who have had previous lumbar spine surgery, and it results in improved sagittal alignment and indirect foraminal decompression.

    Objective To summarize and evaluate the cause and preventions of peri-operational complications associ-ated with surgical treatment for lumbar degenerative diseases. Methods A total of 784 patients with degenerative diseases of lumbar spine undergoing posterior surgical treatment between October 2005 and October 2011 were analyzed retrospectively. Results 80 cases (10. 2%) experienced peri-operation complications in 784 patients. The most common complication was temporary postsurgical sciatica (4. 6%, 36 patients), which was relieved after symptomatic treatment. There were 31 patients (4. 0%) with cerebrospinal fluid leakage, of the 27 patients with dural tears during the operations, 24 had the tear repair im-mediately, and 3 were covered by adipose tissue. 4 patients had CSF leakage without obvious dural tears during the surgery. Wound drainage was kept for 12 days post surgery or less than 50 ml of 24-hour-drainage for the treatment of CSF leakage. There were 9 patients (1. 1%) with neurological deficit after operation, 7 patients recovered completely in 3 months post sur-gery. Only one had numbness of dorsal foot and one had foot drop. Deep wound infections occurred in 4 patients (0. 5%), 2 of these patients recovered after debridement and systemic antibiotics treatments without removal of spinal instrumentation. One patient died of secondary multiple organs failure after debridement and implants extraction. One patient was successfully trea-ted with systemic antibiotics therapy only. Conclusion Comprehensive knowledge anatomy of the lumbar spine, appropriate surgical technique and intense careful skills during operation are critical in preventing, detecting, and managing complications in low back surgeries.%目的:总结分析下腰椎退行性疾病后路手术相关早期并发症发生情况,探讨其发生原因及处理对策。方法回顾分析2005年10月—2011年10月我院采用后路手术治疗下腰椎退行性疾病784例的临床

    Lumbar degenerative disc disease without disc herniation, also known as discogenic pain, is an elusive diagnosis of chronic low back pain. Lumbar provocation discography and fusion surgery have been frequently utilized for several decades as the gold standards for the diagnosis and treatment of symptomatic lumbar discogenic pain, though controversial, based on conjecture, rather than evidence. In addition to lumbar fusion, various other operative and nonoperative modalities of treatments are available in managing chronic lumbar discogenic pain. This review provides an updated assessment of the management of chronic lumbar discogenic pain with a critical look at the many modalities of treatments that are currently available.

    In patients with lumbago-sciatica levomepromazine is a potent supplement to analgesics in pain treatment. The hypothesis that neuroleptics increase the risk of epileptic seizures after metrizamide myelography was not comfirmed in a series of 77 patients, 26 with and 51 without levomepromazine medication, before and after lumbar metrizamide myelography. No differences existed between the groups with regard to the appearance of EEG abnormalities such as slow waves or spikes. Mild side effects were more frequent in the levomepromazine group, except nausea and vomiting. Lumbar metrizamide epidurography in 30 patients did not cause any abnormal EEG.

    In industrialized countries, more than two thirds of the population suffers from low back pain (LBP) in their lifetime. LBP associated with lumbar disc herniation, stenosis, and instability is a well-known and documented entity. On the other hand, the lumbar discogenic pain and facet syndrome are difficult to be clearly identified, and they are not always detectable by imaging. This article describes the causes of these painful syndromes, which are typically without radicular component, explains the modern diagnostic procedures, and provides guidelines for surgical decision making.

    Both target radiofrequency thermocoagulation and collagenase chemonucleolysis are effective micro-invasive therapy means for lumbar intervertebral disc herniation. In order to analyze the clinical effects of target radiofrequency thermocoagulation combined with collagenase chemonucleolysis on lumbar intervertebral disc herniation, the contents of hydroxyproline and glycosaminoglycan were measured and the histological changes of nucleus pulposus was detected in the vitro experiments. Radiofrequency thermocoagulation reduced the hydrolyzation of herniated nucleus pulposus caused by collagenase, as well as the content of hydroxyproline and glycosaminoglycan. Furthermore, 236 patients with lumbar intervertebral disc herniation were treated by target radiofrequency thermocoagulation combined with collagenase chemonucleolysis. The efficiency was evaluated according to Macnab criteria, and the index of lumbar disc herniation (IDH) was compared pre-operation with 3 months post-operation. The post-operative good rate was 66.5% (157/236) at 2 weeks post-operation, and 88.1% (208/236) at 3 months post-operation. In the post-operative follow-up exam, 86.8% of the re-examined cases demonstrated smaller or ablated protrusion, with reduced IDH values from pre-operation, which was statistically significant. No serious complications were detected intra-operatively and post-operatively. In conclusion, target radiofrequency combined with collagenase chemonucleolysis was an effective and safe method for treatment of lumbar intervertebral disc herniation.

    Full Text Available Background and aim: Lumbar disk herniation is one of the most common causes of surgery in the spine with a variety of signs and symptoms. Sensory and motor deficits, as well as reflex and autonomic abnormalities may be seen. This study aimed to investigate characteristics and neurological manifestations in a series of operated cases with lumbar disc herniation. Methods: In a retrospective setting, profiles of 163 operated cases with lumbar disc herniation were reviewed. Demographics as well as preoperational sign and symptoms were extracted and evaluated. Results: There were 86 females and 77 males with a mean age of 44.85±0.91 (range: 23-78 years in the studied population. The most common involved levels were L4-L5 and L5-S1, respectively. Low back pain, radicular pain, and positive Lasegue test were documented in 98.2%, 96.9% and 77.3% of the patients, respectively. Sensory, motor and reflexive abnormalities were documented in 66.3%, 51.5% and 19.6% of the cases, respectively. Sphincter and sexual dysfunction was presented in 4.9% and 1.2%, respectively. Conclusion: Clinical and neurological signs of operated patients with lumbar disc herniation in the studied center are not far different from available reports in this regard.

    Patients with alcaptonuria frequently complain of pain in the large joints and the spinal column, this condition is being assumed to be normal. It is very rare for patients with ochronosis to undergo lumbar surgery since the disk protrusion is not characteristic for them and overlaps with the general complaints due to the spondiloarthritic and stenotic changes. To prove the possibility of a lumbar disc herniation in a patient with alcaptonuria as a real entity that causes lumbar and radiculalgic complaints. A case of a 33-year old patient with alcaptonuria and lumbar disc herniation is presented. The case is presented together with its clinical course, the diagnostic techniques, the surgical findings, histological results and the treatment outcome. After the surgical treatment the patient's complaints were alleviated and almost no complaints were registered, during the next follow-up. The most common symptoms seen in alcaptonuria are complaints of pain in large joints and back pain. They are usually associated with the main disease. The case we present demonstrates that even there is a small likelihood for a prolapsed lumbar disk, it should be sought in such patients as the surgical treatment is able to yields a positive results.

    Vertebral axial decompression (VAX-D) is a form of spinal traction that is widely promoted as an effective and safe treatment of degenerated and herniated lumbar intervertebral disks. Information targeted at the general public emphasizes that the treatment is completely risk-free. We describe a patient with a large lumbar disk protrusion who experienced sudden, severe exacerbation of radicular pain during a VAX-D therapy session. Follow-up magnetic resonance imaging of the lumbar region showed marked enlargement of the disk protrusion, and urgent microdiskectomy was required. To our knowledge, this is the first reported complication of VAX-D therapy. This case shows that VAX-D therapy has the potential to cause sudden deterioration requiring urgent surgical intervention.

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

    2011-07-01

    Gluteal compartment syndrome (GCS) is an extremely rare and potentially devasting disorder, most commonly caused by gluteal muscle compression in extend periods of immobilization. We report a 65-year-old obese man with hypertension, diabetes mellitus type 2 and hypercholesterolemia underwent lumbar spine surgery in knee-chest position because of degenerative lumbar stenosis. Perioperative hypotension occurred. After surgery, the patient developed increasing pain in the buttocks of both sides and oliguria with darkened urine. Stiffness, tenderness and painful swelling of patients gluteal muscles of both sides, high creatine phosphokinase level, myoglobulinuria and oliguria led to diagnosis of bilateral GCS, complicated by severe rhabdomyolysis (RM) and acute renal failure. In conclusion, obese patients with vascular risk factors and perioperative hypotension may be at risk for developing bilateral GCS and RM when performing prolonged lumbar spine surgery. Early diagnosis and treatment is important, as otherwise, the further course may be fatal.

    The purpose of this article is to evaluate radiographically degenerative spondylolisthesis of the lumbar spine, with the main focus on the configuration of posterior elements. A comparative study between 49 cases of degenerative spondylolisthesis and 99 cases of other lumbar disorders was performed, using 13 radiographical parameters. The results clearly indicate the posterior elements of degenerative spondylolisthesis shifted horizontally and sagittally to allow slipping. This was due to the weak bony hook mechanism. Furthermore, almost all facet joints were morphologically classified as sagittal or intermediate type. Another meaningful difference was the alignment of the lumbar spine which showed an increase in both lordosis and lumbosacral angle. On the other hand, the level of Jacoby's line was almost the same in both groups. These characteristic configurations could be the cause of listhesis, although further study should be carried out to elucidate whether they are present at the non-listhetic stage. (author).

    The aim of this study was to demonstrate the feasibility of MR-guided lumbar sympathicolysis (LSL) in a non-selected patient population. One hundred one MR-guided LSL procedures were performed in 89 patients according to Haaga's technique using a horizontally open clinical MR system (0.2 T) and non-ferromagnetic 20-G cannulas (neurolysis, n=93; blockade, n=8). Only gradient-recalled sequences in either single or multislice mode [fast imaging with steady-state precession (FISP) and fast low-angle shot] were applied for anatomical survey and needle guiding. Bupivacaine injection was monitored with MR fluoroscopically. Fluid distribution was subsequently documented in a CT scan in 65 patients. Ninety-one LSL procedures could be successfully completed. Ten patients were not treated using MR due to patient inconvenience, severe motion artifacts (n=4 each), excessive spondylophytes, and retroperitoneal hematoma (n=1 each). One case of ureteral necrosis occurred. Motion artifacts were rated less severe in single-slice FISP sequences and in obese patients. An average of 3.48 sequence measurements were required for definitive needle placement. Average table time was 32.3 min. An MR-guided LSL is feasible and can be performed with acceptable safety and time effort. It can be recommended for repeated sympathetic blockades in younger patients to avoid cumulative irradiation associated with CT guidance. (orig.)

    Our aim was to establish the normal range of MRI findings after successful lumbar discectomy. We prospectively examined 34 consecutive patients with an excellent clinical outcome by MRI 6 weeks and 6 months after surgery. All examinations included sagittal and axial spin-echo (SE) T1-weighted images before and after intravenous gadolinium-DTPA and fast SE T2-weighted images. Contrast enhancement along the surgical tract was seen in all patients 6 weeks and 6 months after surgery. After 6 months minimal or no mass effect on the dural sac by epidural scar was seen. In 20 % of patients there was recurrent disc herniation, with mass effect. Enhancing nerve roots were seen in 20 % of patients 6 weeks postoperatively, and half of these were associated with recurrent disc herniation at the same side. None of these patients still showed nerve root enhancement 6 months after surgery. Postoperative MRI studies must be interpreted with great care since the features described in the failed back surgery syndrome are also found, to some extent, in asymptomatic postoperative patients.

    Postural deviations can predispose an individual to increased injury risk. Specifically, lumbar deviations are related to increased low back pain and injury. Dancers and gymnasts are anecdotally suggested to have exaggerated lumbar lordosis and subsequently may be at increased risk of lumbar pathologies. Our objective was to examine lumbar lordosis levels in dancers and gymnasts. We examined lumbar lordosis in 47 healthy collegiate females (17 dancers, 29 gymnasts; mean age 20.2 ± 1.6 yrs) using 2-dimensional sagittal plane photographs and the Watson MacDonncha Posture Analysis instrument. Participants' lordosis levels were cross-tabulated and a Mann-Whitney U-test compared lumbar lordosis between groups (plordosis deviations. The distribution of lordosis was similar across groups (p=0.22). Most dancers and gymnasts had moderate or marked lumbar lordosis. The extreme ranges of motion required during dancing and gymnastics may contribute to the participants' high lumbar lordosis. Instructors should be aware that there may be links between repetitive hyperextension activities and lumbar lordosis levels in dancers and gymnasts. Thus, they should proactively examine lumbar lordosis in their dancers and gymnasts. How much age of training onset, regimens, survivor bias, or other factors influence lumbar lordosis requires study. Longitudinal studies are also needed to determine if lumbar lordosis levels influence lumbar injury incidence in dancers and gymnasts.

    Change in lumbar lordosis was measured in patients that had undergone posterolateral lumbar fusions using transpedicular instrumentation. The biomechanical effects of postoperative lumbar malalignment were measured in cadaveric specimens. To determine the extent of postoperative lumbar sagittal malalignment caused by an intraoperative kneeling position with 90 degrees of hip and knee flexion, and to assess its effect on the mechanical loading of the instrumented and adjacent segments. The importance of maintaining the baseline lumbar lordosis after surgery has been stressed in the literature. However, there are few objective data to evaluate whether postoperative hypolordosis in the instrumented segments can increase the likelihood of junctional breakdown. Segmental lordosis was measured on preoperative standing, intraoperative prone, and postoperative standing radiographs. In human cadaveric spines, a lordosis loss of up to 8 degrees was created across L4-S1 using calibrated transpedicular devices. Specimens were tested in extension and under axial loading in the upright posture. In patients who underwent L4-S1 fusions, the lordosis within the fusion decreased by 10 degrees intraoperatively and after surgery. Postoperative lordosis in the proximal (L2-L3 and L3-L4) segments increased by 2 degrees each, as compared with the preoperative measures. Hypolordosis in the instrumented segments increased the load across the posterior transpedicular devices, the posterior shear force, and the lamina strain at the adjacent level. Hypolordosis in the instrumented segments caused increased loading of the posterior column of the adjacent segments. These biomechanical effects may explain the degenerative changes at the junctional level that have been observed as long-term consequences of lumbar fusion.

    Retrospective analysis. The object is to assess the correlation between whole lumbar lordosis (LL) and the segmental angle (SA) after single-level anterior lumbar interbody fusion for degenerative lumbar spondylolisthesis. The restoration of the SA at lower lumbar spine is meaningful, considering it contributes approximately 60% of LL, and revision surgery due to flat back or adjacent segment pathology was necessary decades after the initial surgery. However, little is known about the change of whole lumbar curvature after single-level lower lumbar fusion surgery, especially for balanced spine. We included 41 consecutive patients (M:F=9:32; mean age, 59.8±9.3 y) with a single-level anterior lumbar interbody fusion surgery for low-grade degenerative spinal spondylolisthesis, with C7 plumb line of sagittal alignment was influenced by single SA. Therefore, obtaining adequate segmental lordosis is desirable considering the effect on the whole spine for a long time.

  6. MANAGEMENT OF LUMBAR SPINAL CANAL STENOSIS

    Full Text Available BACKGROUND Spinal stenosis is one of the most common conditions in the elderly. It is defined as a narrowing of the spinal canal. The term stenosis is derived from the Greek word for narrow, which is “Stenos”. The first description of this condition is attributed to Antoine portal in 1803. Verbiest is credited with coining the term spinal stenosis and the associated narrowing of the spinal canal as its potential cause. [1-10] Kirkaldy–Willis subsequently described the degenerative cascade in the lumbar spine as the cause for the altered anatomy and pathophysiology in spinal stenosis. [11-15] If compression does not occur, the canal should be described as narrow but not stenotic. Some studies defined lumbar spinal stenosis as a “narrowing of the osteoligamentous vertebral canal and/or the intervertebral foramina causing compression of the thecal sac and/or the caudal nerve roots; at a single vertebral level, narrowing may affect the whole canal or part of it” (Postacchini 1983. This definition distinguished between disc herniation and stenosis. [16] . The most common type of spinal stenosis is caused by degenerative arthritis of the spine. Hypertrophy and ossification of the posterior longitudinal ligament which usually are confined to the cervical spine, and diffuse idiopathic skeletal hyperostosis (DISH syndrome also may result in an acquired form of spinal stenosis. Congenital forms caused by disorders such as achondroplasia and dysplastic spondylolisthesis are much less common. Congenital spinal stenosis usually is central and is evident or imaging studies. Idiopathic congenital narrowing usually involves the anteroposterior dimension of the canal secondary to short pedicles; the patient otherwise is normal. In contrast, in achondroplasia, the canal is narrowed in the anteroposterior plane owing to shortened pedicles and in lateral dimension because of diminished interpedicular distance. Acquired forms of spinal stenosis usually are

    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.)

    A new musculoskeletal model for the lumbar spine is described in this paper. This model features a rigid pelvis and sacrum, the five lumbar vertebrae, and a rigid torso consisting of a lumped thoracic spine and ribcage. The motion of the individual lumbar vertebrae was defined as a fraction of the net lumbar movement about the three rotational degrees of freedom: flexion-extension lateral bending, and axial rotation. Additionally, the eight main muscle groups of the lumbar spine were incorporated using 238 muscle fascicles with prescriptions for the parameters in the Hill-type muscle models obtained with the help of an extensive literature survey. The features of the model include the abilities to predict joint reactions, muscle forces, and muscle activation patterns. To illustrate the capabilities of the model and validate its physiological similarity, the model's predictions for the moment arms of the muscles are shown for a range of flexion-extension motions of the lower back. The model uses the OpenSim platform and is freely available on https://www.simtk.org/home/lumbarspine to other spinal researchers interested in analyzing the kinematics of the spine. The model can also be integrated with existing OpenSim models to build more comprehensive models of the human body.

  9. Economic impact of minimally invasive lumbar surgery

    2015-01-01

    Cost effectiveness has been demonstrated for traditional lumbar discectomy, lumbar laminectomy as well as for instrumented and noninstrumented arthrodesis. While emerging evidence suggests that minimally invasive spine surgery reduces morbidity, duration of hospitalization, and accelerates return to activites of daily living, data regarding cost effectiveness of these novel techniques is limited. The current study analyzes all available data on minimally invasive techniques for lumbar discectomy, decompression, short-segment fusion and deformity surgery. In general, minimally invasive spine procedures appear to hold promise in quicker patient recovery times and earlier return to work. Thus, minimally invasive lumbar spine surgery appears to have the potential to be a cost-effective intervention. Moreover, novel less invasive procedures are less destabilizing and may therefore be utilized in certain indications that traditionally required arthrodesis procedures. However, there is a lack of studies analyzing the economic impact of minimally invasive spine surgery. Future studies are necessary to confirm the durability and further define indications for minimally invasive lumbar spine procedures. PMID:25793159

    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 is common, costly, and disabling for active duty military personnel and veterans. The evidence is unclear on which management approaches are most effective. The purpose of this study was to assess the effectiveness of lumbar extensor high-intensity progressive resistance exercise (HIPRE) training versus control on improving lumbar extension muscular strength and core muscular endurance in soldiers. A randomized controlled trial was conducted with active duty U.S. Army Soldiers (n = 582) in combat medic training at Fort Sam Houston, Texas. Soldiers were randomized by platoon to receive the experimental intervention (lumbar extensor HIPRE training, n = 298) or control intervention (core stabilization exercise training, n = 284) at one set, one time per week, for 11 weeks. Lumbar extension muscular strength and core muscular endurance were assessed before and after the intervention period. At 11-week follow-up, lumbar extension muscular strength was 9.7% greater (p = 0.001) for HIPRE compared with control. No improvements in core muscular endurance were observed for HIPRE or control. Lumbar extensor HIPRE training is effective to improve isometric lumbar extension muscular strength in U.S. Army Soldiers. Research is needed to explore the clinical relevance of these gains.

    This retrospective study evaluates lumbar lordosis in 43 patients before and after Harrington instrumentation into the lumbar spine. The authors measured overall lumbar lordosis, lordosis of unfused lumbar levels, and sagittal vertical axis. Lordosis decreased progressively in lower levels of fusion. The increase in lordosis below the fusion did not compensate for the overall loss of lordosis. The sagittal vertical axis moved forward, producing a subtle, asymptomatic form of flat back syndrome.

    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 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.

    Full Text Available Background. Degenerative lumbar spinal stenosis (DLSS is a common cause of low back and leg pain in the elderly. Conservative treatment seldom results in sustained improvement.Methods. Fifty-six patients (33 women, 23 men older than 50 years (mean 67 years, range 51 to 82 years and with no prior low back surgery were treated from 1993 to 1999 for clinical and radiologic evidence of DLSS. The goal of this study was to describe the results of decompressive laminectomy with or without fusion in terms of reoperation, severity of back pain, leg pain and patient satisfaction. Answers to Swiss spinal stenosis questionnaires completed before surgery and one to five years afterwards were evaluated. Seven patients (12.5% with degenerative spondylolisthesis, scoliosis and/or more radical facetectomies received fusion.Results. Of the 56 patients in the original cohort, two were deceased and two had undergone reoperation by follow-up. Forty-eight patients answered questionnaires. Average duration of follow-up was 2.5 years. More than 70 percent of the respondents had no or only mild back or buttock pain at follow-up and more than 60 percent were able to walk more than 500 m. Added fusion reduced the incidence of low back pain and pain frequency, and increased walking distance (ANOVA.Conclusions. Eighty-one percent of patients were satisfied with the results of surgery and 87.5% would choose to have the operation again if they had the choice. Decompressive laminectomy for DLSS yields best results if instrumented fusion is included in the procedure.

    Lumbar hernia is uncommon and occurs in Grynfeltt's triangle on the left side, more frequently in men than in women. Acquired lumbar hernias are the result of iliac crest bone harvest or blunt trauma and seat belt injuries in road accidents. Many surgical options have been reported for repairing this hernia through primary closure of the defect or through use of aponeurotic or prosthetic materials. The Dowd technique is the technique most often used. The authors describe a patient with posttraumatic inferior triangle lumbar hernia who underwent laparoscopy and, 10 days later, laparotomy. Both procedures failed. Finally, a novel lumbotomic surgical approach was used, involving the Dowd technique and prosthetic mesh. The patient was free of recurrence 3 months after the procedure.

    2013-04-01

    Field study, cross-sectional study to measure the posture and sEMG of the lumbar spine during office work for a better understanding of the lumbar spine within such conditions. There is high incidence of low back pain in office workers. Currently there is little information about lumbar posture and the activity of lumbar muscles during extended office work. Thirteen volunteers were examined for around 2h of their normal office work. Typical tasks were documented and synchronised to a portable long term measuring device for sEMG and posture examination. The correlation of lumbar spine posture and sEMG was tested statistically. The majority of time spent in office work was sedentary (82%). Only 5% of the measured time was undertaken in erect body position (standing or walking). The sEMG of the lumbar muscles under investigation was task dependent. A strong relation to lumbar spine posture was found within each task. The more the lumbar spine was flexed, the less there was activation of lumbar muscles (P postures. Because of very low activation of lumbar muscles while sitting, the load is transmitted by passive structures like ligaments and intervertebral discs. Due to the viscoelasticity of passive structures and low activation of lumbar muscles, the lumbar spine may incline into de-conditioning. This may be a reason for low back pain.

    Previous imaging studies have shown that degenerative disk disease is more common in the competitive female gymnast than in asymptomatic nonathletic people of the same age training to any degree. However, results of exposure-discordant monozygotic and classic twin studies suggest that physical loading specific to occupation and sport has a relatively minor role in disk degeneration, beyond that of upright postures and routine activities of daily living. Intensive, regular, and prolonged dancing causes strain on the lumbar spine and can trigger or accelerate the development of degenerative diskopathy. Cross-sectional study; Level of evidence, 3. Forty volunteer female dancers (20 ballet and 20 flamenco) aged between 18 and 31 years (mean = 24.2) underwent magnetic resonance imaging of the lumbar spine. They were compared against a control group of 20 women of the same age. A descriptive analysis was done, and the 2 groups were compared by contingency table analysis using the Pearson chi-square test complemented by an analysis of residuals. Results Nine of the 20 women (45%) in the control group had disk degeneration compared with 13 of the 40 (32.5%) women in the dancer group, with a chi-square of 0.897 (not significant). There were 12 degenerated disks of the 100 explored (12%) in the control group compared with 21 of the 200 explored (10.5%) in the dancer group (chi-square = 0.153; not significant). Dancing cannot be considered a risk factor for lumbar disk degeneration in women. The present study indicates that dancing has no negative effect on the development of degenerative diskopathy.

  3. Asymmetry of the multifidus muscle in lumbar radicular nerve compression

    The multifidus muscle is the only paraspinal lumbar muscle that is innervated by a single nerve root. This study aimes to evaluate if the asymmetry of the multifidus muscle is related to the severity of compression of the nerve root or the duration of radiculopathy. MRI scans of 79 patients with symptomatic single level, unilateral, lumbar radiculopathy were reviewed for this retrospective case series with a nested case-control study. The cross-sectional area (CSA) of the multifidus muscle and the perpendicular distance of the multifidus to the lamina (MLD) were measured bilaterally by two radiologists and set into relation to the severity of nerve compression, duration of radiculopathy and probability of an indication for surgical decompression. In 67 recessal and 12 foraminal symptomatic nerve root compressions, neither the MLD ratio (severe 1.19 ± 0.55 vs less severe nerve compression: 1.12 ± 0.30, p = 0.664) nor the CSA ratio (severe 1 ± 0.16 vs less severe 0.98 ± 0.13, p = 0.577) nor the duration of symptoms significantly correlated with the degree of nerve compression. MR measurements of multifidus were not different in patients with (n = 20) and those without (n = 59) clinical muscle weakness in the extremity caused by nerve root compression. A MLD >1.5 was, however, associated with the probability of an indication for surgical decompression (OR 3, specificity 92 %, PPV 73 %). Asymmetry of the multifidus muscle correlates with neither the severity nor the duration of nerve root compression in the lumbar spine. Severe asymmetry with substantial multifidus atrophy seems associated with the probability of an indication of surgical decompression. (orig.)

    Retrospective study of a consecutive patient series. To review the radiographic classification of patients with sagittal imbalance due to lumbar degenerative kyphosis (LDK) and to determine correlation between thoracic and lumbar curve. Lumbar degenerative kyphosis is one of the common spinal deformities in Asian countries, especially Korea and Japan. However, there have been few studies regarding the classification and treatment of this disease. Seventy-eight patients with LDK were analyzed and classified according to the standing lateral whole spine findings. Total lumbar lordosis (L1-S1), thoracic kyphosis (T5-T12), sacral slope, thoracolumbar angle (T11-L1), and sagittal vertical axis (SVA) were measured on the lateral view of the whole spine. Spinal curve deformities were classified into 2 groups according to the thoracolumbar (T-L) junction angle: flat or lordotic angle (Group 1; N = 53) and kyphotic angle (Group 2; N = 25). In Group 1, significant correlations between the thoracic and lumbar curves (r = 0.772, P sagittal thoracic compensated group. In contrast, In Group 2, no correlation was found between the thoracic and lumbar curves in the decompensated group (r = 0.179, P = 0.391), but we found a significant correlation between lordosis and sacral slope (r = 0.442, P = 0.027). By this result, Group 2 was classified as sagittal thoracic decompensated group. There was significant difference in SVA between 2 groups (P = 0.020). The angle of the thoracolumbar junction is an important parameter in determining whether a sagittal thoracic compensatory mechanism exists in LDK. We assumed that existence of a compensatory mechanism in the proximal spine is central to the determination of the fusion levels in the treatment of LDK.

    In deformity surgery, anterior lumbar interbody fusion provides excellent biomechanical support, creates a broad surface area for arthrodesis, and induces lordosis in the lower lumbar spine. Preoperative MRI, plain radiographs, and, when available, CT scan should be carefully assessed for sacral slope as it relates to pubic symphysis, position of the great vessels (especially at L4/5), disc space height, or contraindication to an anterior approach. This video demonstrates the steps in an anterior surgical procedure with minimal open exposure. The video can be found here: https://youtu.be/r3bC4_vu1hQ .

Treatment options for patients with chronic lumbar discogenic pain unresponsive to conservative management include total disc replacement (TDR or lumbar fusion. Until recently, only two lumbar TDRs had been approved by the US Food and Drug Administration - the Charité Artificial Disc in 2004 and the ProDisc-L Total Disc Replacement in 2006. In June 2015, a next-generation lumbar TDR received Food and Drug Administration approval - the activL® Artificial Disc (Aesculap Implant Systems. Compared to previous-generation lumbar TDRs, the activL® Artificial Disc incorporates specific design enhancements that result in a more precise anatomical match and allow a range of motion that better mimics the healthy spine. The results of mechanical and clinical studies demonstrate that the activL® Artificial Disc results in improved mechanical and clinical outcomes versus earlier-generation artificial discs and compares favorably to lumbar fusion. The purpose of this report is to describe the activL® Artificial Disc including implant characteristics, intended use, surgical technique, postoperative care, mechanical testing, and clinical experience to date.

    Study Design Cohort study. Purpose This study primarily aimed to evaluate the serum levels of tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-4 in patients with lumbar radiculopathy 1 and 12 months after microdiscectomy. Overview of Literature Lumbar radiculopathy is possibly caused by inflammatory changes in the nerve root. The intraneural application of pro-inflammatory cytokines induces behavioral signs associated with pain. Anti-inflammatory cytokine treatment effectively reduces hyperalgesia. Methods The role of TNF-α and IL-4 in long-lasting lumbar radiculopathy was addressed. A total of 262 patients were recruited from Anqing Hospital, Anhui Medical University. During inclusion at 1 and 12 months, serum concentrations of TNF-α and IL-4 were analyzed by enzyme-linked immunosorbent assay, and pain intensity was reported on a 0–10 cm visual analog scale (VAS). Results Sixty six patients had VAS <3 and 196 patients had VAS ≥3. Serum concentrations of pro-inflammatory TNF-α and anti-inflammatory IL-4 in patients with lumbar radiculopathy related to disc herniation were measured at 1- and 12-month follow-up. TNF-α decreased in both VAS groups with time. In contrast, IL-4 increased in both groups at 1 month and then decreased gradually until month 12. The changes in serum levels of TNF-α and IL-4 over time between the VAS ≥3 and VAS <3 groups were significantly different. Conclusions Chronic lumbar radiculopathy may be associated with high level of pro-inflammatory substances, such as TNF-α, in serum after disc herniation, and elevated anti-inflammatory cytokine in patients with lumbar radiculopathy may indicate a favorable outcome.

    Full Text Available Background. Lower back pain is a common reason for disability and the most common cause is lumbar disc herniation. Percutaneous epidural adhesiolysis has been applied to relieve pain and increase the functional capacity of patients who present this condition. Objectives. In this study, we retrospectively evaluated the factors which predict the outcome of percutaneous epidural adhesiolysis in patients who were diagnosed with lumbar disc herniation. Methods. Electronic medical records of patients diagnosed with lumbar disc herniation who have received percutaneous epidural adhesiolysis treatment were reviewed. The primary outcome was the factors that were associated with substantial response of ≥4 points or ≥50% of pain relief in the numerical rating scale pain score 12 months after the treatment. Results. Multivariate logistic regression analysis demonstrated that the presence of high-intensity zone (HIZ at magnetic resonance imaging was a predictor of substantial response to percutaneous epidural adhesiolysis for 12 months (P=0.007. The presence of a condition involving the vertebral foramen was a predictor for unsuccessful response after 12 months (P=0.02. Discussion and Conclusion. The presence of HIZ was a predictor of favorable long-term outcome after percutaneous epidural adhesiolysis for the treatment of lower back pain with radicular pain caused by lumbar disc herniation.

    As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy.

    Francisco Eudison da Silva Maia

    2015-12-01

    Full Text Available The growing incidence of low back pain is a problem of public health, causing physical, economical and psychosocial damages. Such pain is correlated with types of work and its execution, such as remaining in determinate postures for long periods and repetition of mechanically stressful movements, and its consequent metabolic damage on the composing structures of the lumbar spine. Thus, this study approaches the aetiology of the mechanical and biological factors related to low back pain, contributing to the enrichment of the discussion of proposed interventionist therapies that lead to the reduction or remission of lumbar pain. For such, a literature review was performed through researching publications in the period from 2000 to 2012 in orthopedics, osteopathy, and rheumatology textbooks, as well as newspapers and databases such as Lilacs, Bireme, and Scielo, using the keywords: low back pain, physiotherapy, and health. It was observed that knowing the aetiology of low back pain is important for the formulation of a therapeutic strategy. The base for the therapeutic strategy should be composed of: the evaluation of the individual, the individual's work and the movements necessary for it, and the environment where such work is performed. The physiotherapist has a wide and effective therapeutic arsenal for the performance of his/her interventions. Treatment success depends on the selection and/or combination of the techniques that best attend the patients' needs. Thus, physiotherapy comes as an indispensable tool in the promotion of health and improvement of life quality.

    The purpose of this study was to use a noninvasive method to determine the effect of pelvic tilt on the lumbar spine geometry in the sagittal plane. Five healthy male subjects were instructed in performing active forward and backward pelvic tilt manoeuvres in the standing position. The lumbar spine geometry (severity of lordosis, pelvis and lumbar vertebrae orientations) was estimated with a lumbar spine geometric model. The voluntary backward pelvic tilt succeeded in reducing the depth of the lumbar spine curvature, but the forward tilt did not change it. Both pelvic tilt manoeuvres influenced the absolute orientations of the lower lumbar vertebrae and the relative orientations of some lumbar vertebrae. Interestingly, the L5/S1 joint showed was little affected by the pelvic tilt manoeuvres.

    We investigated the effects of continuous lumbar traction in patients with lumbar disc herniation on clinical findings, and size of the herniated disc measured by computed tomography (CT). In this prospective, randomized, controlled study, 46 patients with lumbar disc herniation were included, and randomized into two groups as the traction group (24 patients), and the control group (22 patients). The traction group was given a physical therapy program and continuous lumbar traction. The control group was given the same physical therapy program without traction, for the same duration of time. Data for the clinical symptoms and signs were collected before and after the treatment together with calculation of a herniation index, from the CT images that showed the size of the herniated disc material. In the traction group, most of the clinical findings significantly improved with treatment. Size of the herniated disc material in CT decreased significantly only in the traction group. In the traction group the herniation index decreased from 276.6+/-129.6 to 212.5+/-84.3 with treatment (p0.05). Patients with greater herniations tended to respond better to traction. In conclusion, lumbar traction is both effective in improving symptoms and clinical findings in patients with lumbar disc herniation and also in decreasing the size of the herniated disc material as measured by CT.

    Objective: To observe the clinical effect of electroacupuncture (EA) combined with tuina on acute lumbar sprain and lumbar muscle tone before and after treatment. Methods: A total of 130 acute lumbar sprain cases were randomly allocated into an observation group and a control group, 65 in each group. Cases in the observation group were treated with EA combined with tuina, whereas cases in the control group were treated with Diclofenac Sodium Dual Release Enteric-coated capsules. The muscle tones in two groups were tested before and after treatment. Results: The recovery rate and overall response rate in the observation group were 66.2% and 93.8% respectively, versus 56.9% and 87.7% in the control group, showing no between-group statistical significances (P>0.05). After treatment, the force-displacement area under curve (AUC) in both groups showed a significance difference (P Conclusion: Both EA combined with tuina and aforementioned oral medication have remarkable effects for acute lumbar sprain, and the former can better improve the lumbar muscle tone in patients with acute lumbar sprain.

    Full Text Available Background: Lumbar radiculopathy is a disease of the spinal nerve root generally accompanied by radicular pain in dermatomal distribution and/or neurologic symptoms. The previous studies were focusing on finding the disability and pain caused due to Lumbar Radiculopathy. This study is focusing on the disability, pain, range of motion of the spine and SLR. The objective of the study is to evaluate the effectiveness of Mckenzie method with TENS on reducing symptoms and disability of Lumbar radiculopathy. Methods: In the present prospective study patients with Lumbar radicular pain due to disc herniation or prolapse at level L4, L5 & S1 were randomized into two groups – Group A and Group B. the study included 40 patients, with 20 in each group. The selection criteria was based on the following - with age group 22-55years, both sexes – male and female, with radicular pain in L4, L5 & S1 dermatomes, disabling leg pain for 6-12 weeks duration, evidence of disc herniation confirmed on MR imaging. The radicular pain was measured using the SLR test, pain was measured using the VAS scale of 0 – 100, disability was measured using the MODI and Lumbar Spine ROM was measured using the MMST. Group-A were treated with McKenzie methods with TENS and Group-B were treated with general exercise with TENS. Results: This study showed that there was a significant reduction of pain on the VAS, improvement in SLR, lumbar spine range of motion using MMST and disability using MODI for both the groups. The statistical analysis found that experimental group showed earlier control of all the outcome measures when compared to controlled group at the end of the 6th week. Conclusion: After 6 weeks of Mckenzie method with TENS intervention for 30 minutes for 5 days in week the statistical analysis concluded that the experimental group had significantly faster rates of reducing the symptoms of lumbar radiculopathy and reducing the disability due to lumbar radiculopathy.

    Lumbar facet cysts are frequently found in patients with facet degeneration and segmental instability. When the facet cyst is localized in the neural foramina and lateral recess or becomes large, it can cause radiculopathy or neurogenic claudication. These symptomatic cysts are typically treated interventionally with drainage and a corticosteroid injection or attempts via overinflation to rupture the cyst; however, these procedures have a significant recurrence rate (up to 50%) and often need to be repeated or lead to lumbar surgery if unsuccessful.   This is the first report of using targeted radiofrequency (RF) current as an adjunct to cyst drainage. Although RF has been used for years to treat facet pain indirectly by targeting the medial facet nerve branches, with this technique, under image guidance, the actual cyst is percutaneously drained and then cauterized along with the associated facet capsule, where the original cyst developed. This has improved overall results with less cyst recurrence than previous percutaneous methods and was documented with both intermediate and long-term followup clinically and with magnetic resonance imaging (MRI) scans. This report reviews the underlying anatomy and pathology of the facet joint relating to the development of facet cysts and how current percutaneous treatments for lumbar facet cysts can be supplemented and improved by adding targeted RF ablation to the percutaneous options available to treat a lumbar facet cyst.

    The classification of pelvic girdle pain can only be reached after lumbar causes have been excluded by a clinical examination. During clinical examination, the posterior pelvic pain provocation test is a well-established method for verifying pelvic girdle pain. However, a criticism of pelvic pain provocation tests is that they may have an effect on lumbar structures, thus yielding false-positive results. The posterior pelvic pain provocation test was performed with four groups of patients: patients with computed tomography-verified disc herniations (1) on the waiting list for surgery (14 women; 9 men); (2) 6 weeks after disc surgery (18 women, 12 men); (3) pregnant women seeking care for pelvic girdle pain (n = 25); and (4) women with persistent pelvic girdle pain after delivery (n = 32). The sensitivity of the posterior pelvic pain provocation test was 0.88 and the specificity was 0.89. The positive predictive value was 0.89 and the negative predictive value was 0.87. Analysis of only women showed similar results. In our study, the posterior pelvic pain provocation test was negative in patients with a well-defined lumbar diagnosis of lumbar disc herniation, both before and after disc surgery. Our results are an important step toward the more accurate classification of lumbopelvic pain.

    Lumbar spinal stenosis (LSS) is a common cause of chronic lumbar pain and disability. Conventional therapy approaches include analgesics and spinal surgery. Topical cantharidin applications are used for the treatment of severe chronic lumbar pain in traditional European medicine (TEM). We tested the pain-relieving effect of lumbar cantharidin blisters in a non-randomised controlled pilot study. 28 consecutive patients with manifest LSS were included. The first 20 patients received a cantharidin blister, 8 patients served as controls (waiting list). Pain was assessed by means of a numeric visual analogue scale (VAS; 0 indicating no pain, 10 indicating strongest pain). Treatment started after a 3-day run-in phase, the blister was applied once for 12 h. Patients were comparable with respect to baseline pain. In the blister group, the pain score continuously improved from 7.2 +/- 2.1 at baseline to 2.9 +/- 2.3 (VAS) at day 7, whereas the score remained unchanged in control patients. Adjusted for baseline, the difference between the blister and the control group was estimated at 4.1 (95% CI: 2.4-5.9, p blisters, a clinically relevant pain-relieving short-term effect on LSS was observed. As the trial was non-randomised and only included a limited number of patients, the results should be interpreted with caution. Copyright 2009 S. Karger AG, Basel.

    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

    We performed posterior lumbar interbody fusion (PLIF) on 7 patients with rheumatoid spondylitis (RA) of the lumbar spine with severe low-back pain and/or cauda equina symptoms, and evaluated the effectiveness of PLIF for the lumbar spinal instability in RA secondary to destruction of the anterior elements, including vertebral endplates and the apophyseal joint. The subjects were 7 patients with classic RA, 2 men and 5 women, mean age 65 years old, and the mean duration of RA was 21 years. All had severe low-back pain and difficulty with walking. According to the ARA classification, the patients were at stage 3 or worse and in class 3. Diagnostic imaging including magnetic resonance imaging (MRI), tomography, myelography, and computed tomographic myelography (CTM) of the lumbar spine clearly delineated pathology, destruction of the vertebral endplate, subluxation, and cauda compression which can be well treated with PLIF. We performed L4/5PLIF (5 cases), L3/4 and L4/5 PLIF (2 cases), and posterior fixation with instruments for anterior column repair and stabilization and posterior decompression. Autografts (all cases) and Brantigan IF cage (2 cases) were used. Stable fixation of the lumbar spine was achieved after surgery, and improvement in gait and activities of daily living were achieved through the relief of low-back pain and radicular pain; the mean duration of follow-up was 22 months. Postoperative, plain radiography, CT, and MRI revealed the enlargement of the lumbar canal and fusion and incorporation of grafted bone, but in some cases, collapse of graft, migration of pedicle screw, instability of adjacent level, and collapse of adjacent vertebra were noted. PLIF with spinal instruments is a preferred treatment for rheumatoid spondylitis of the lumbar spine, but in the mutilating type of RA with severe osteoporosis, PLIF in combination with a long fixation system and/or augmentation of the vertebral bodies might be needed.

    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.

    Prospective observational study OBJECTIVES.: Quantify the amount of lumbar lordosis achieved on a hinged operative table in neutral, flexion, and extension. Hinged operative tables may allow surgeons to adjust lumbar spine positioning intraoperatively. The amount of lumbar lordosis in neutral, flexion, and extension positions has not been quantified prospectively using a hinged table. Thirty patients undergoing elective lumbar surgery were enrolled. Standing x-rays taken in neutral, maximal flexion, and maximal extension were obtained. Following prone positioning on a hinged operative table, x-rays in neutral, maximal flexion, and maximal extension were taken. Total lumbar lordosis was calculated for all 6 images by two physicians. Disc degeneration was graded using Pfirrmann grades. Lumbar lordosis on the operative table was 56.5 ± 2.1, 43.6 ± 2.2, 63.2 ± 2.0 compared to 46.9 ± 3.1, 33.2 ± 2.8, 52.3 ± 3.3 on the standing films in neutral, flexion, and extension respectively. Average flexion (12.9 ± 1.1) and extension (6.7 ± 1.2) were significantly different from neutral on the table (p < .001). Lumbar lordosis was significantly higher on the operative table (p < .001). Total range of motion was 19.6 ± 1.9 on the table and 19.1 ± 2.0 with standing (p = 0.42). Average Pfirrmann disc grade was 2.77 ± 0.10 which did not correlate with range of motion (p = 0.40). In this cohort, the hinged operative table allowed for a physiologic arc of motion of nearly 20 from flexion to extension. A considerable amount of lumbar sagittal motion can be obtained on hinged operative tables without decreasing overall lumbar lordosis below physiologic levels. 3.

    Study Design A cross-sectional study. Purpose To describe the correlation between lumbar lordosis angle and functional status of patients with chronic mechanical low back pain (CMLBP). Overview of Literature There are different and conflicting opinions regarding the relationship between the degree of lumbar lordosis and functional status of patients with low back pain. Nonetheless, the severity of lordosis is still one of the routine physical exams considered in rehabilitation clinics. Methods The degree of lumbar lordosis of 150 patients with CMLBP was measured by means of Cobb's method using sagittal standing spinal radiographs. Subjects with probable secondary causes of low back pain (trauma, congenital anomaly, spinal infection, rheumatologic problems and history of spinal surgery) were excluded. Besides recording demographic data, their score of functional disability was estimated using Oswestry Disability Questionnaire, one of the most useful and reliable questionnaires. Comparison between these data was made regarding different age and gender groups. Results In this study, 119 subjects were female and 31 male, with an age range of 19-85 years. The average degree of lumbar lordosis was 44.69±11.43 and that of Oswestry disability index (ODI) 30.52%. Although we found a significant direct relationship between age and degree of lumbar lordosis (Pearson's correlation coefficient, p=0.016, r=0.197), while insignificant correlation was seen between the degree of lumbar lordosis and ODI (p=0.129). Conclusions There was no significant correlation between the degree of lumbar lordosis and the score of functional disability with regards to different age groups and gender. PMID:25346808

    We describe an unusual case of a 74-year-old woman who presented with signs and symptoms of small-bowel obstruction and a clinically appreciable, irreducible, left-sided lumbar hernia associated with previous iliac crest bone graft harvesting. Palpation of the hernia demonstrated a small, firm mass within the loops of herniated bowel. CT scanning recognised an intraluminal gallstone at the transition point, establishing the diagnosis of gallstone ileus within an incarcerated lumbar hernia. The proposed explanatory mechanism is that of a gallstone migrating into an easily reducible hernia containing small bowel causing obstruction at the hernia neck by a ball-valve mechanism, resulting in proximal bowel dilation and thus hernia incarceration; it remains unclear when the stone entered the hernia, and whether it enlarged in situ or prior to entering the enteral tract. This is only the second reported instance in the literature of an intraluminal gallstone causing hernia incarceration.

    [Purpose] This study examined the effects of lumbar stabilization exercises on the functional disability and lumbar lordosis angles in patients with chronic low back pain. [Subjects] The subjects were 30 patients with chronic low back pain divided into a lumbar stabilization exercise group (n = 15) and a conservative treatment group (n = 15). [Methods] The lumbar stabilization exercise and conservative treatment groups performed an exercise program and conservative physical treatment, respectively. Both programs were performed 3 times a week for 6 weeks. The degree of functional disability was assessed by the Oswestry disability index, and lumbar lordosis angles were measured by plain radiography. [Results] The Oswestry disability index decreased significantly in the both groups; however, it was significantly lower in the lumbar stabilization exercise group. The lumbar lordosis angle increased significantly in the lumbar stabilization exercise group after treatment and was also significantly greater than that in the conservative treatment group. [Conclusion] Lumbar stabilization exercise is more effective than conservative treatment for improving functional disability and lumbar lordosis angles.

    The purpose of this study was to investigate the effects of lumbar rotational manipulation and lumbar central posteroanterior mobilization on lumbar bending stiffness and flexion and extension range of motion (ROM). A same-subject, repeated-measures, crossover design was used using 32 asymptomatic subjects (16 female and 16 male; mean [SD] age, 25.5 [4.5] years; weight, 65.7 [11.8] kg; and height, 1.70 [0.08] m). Each subject received mobilization or manipulation on 2 different occasions. Bending stiffness was calculated using a 3-point bending model using an electromagnetic tracking device and a force platform; lumbar flexion and extension ROM was measured using an electromagnetic tracking device. All variables were measured pre- and postintervention. Their effect was compared using paired t tests. Manipulation and mobilization did not significantly alter either bending stiffness or lumbar flexion and extension ROM (mobilization: P = .175, P = .613, and P = .535; manipulation: P = .973, P = .323, and P = .439). Bending stiffness changes were not correlated to changes in ROM (Pearson r for stiffness-flexion = -0.102, P = .586; Pearson r for stiffness-extension = 0.014, P = .941). Manipulation and mobilization had no significant effect on bending stiffness or flexion and extension ROM for this group of subjects. Some individual variations in effect were observed.

    Full Text Available Hemophilic pseudotumor involving the spine is extremely uncommon and presents a challenging problem. Preoperative planning, angiography, intra and perioperative monitoring with factor VIII cover and postoperative care for hemophilic pseudotumor is vital. Recognition of the artery of Adamkiewicz in the thoracolumbar junction helps to avoid intraoperative neurological injury. We report the case of a 26-year-old male patient with hemophilia A, who presented with a massive pseudotumor involving the first lumbar vertebra and the left iliopsoas. Preoperative angiography revealed the artery of Adamkiewicz arising from the left first lumbar segmental artery. Excision of pseudotumor was successfully carried out with additional spinal stabilization. At 2 years followup, there was no recurrence and the patient was well stabilized with a satisfactory functional status. Surgical excision gives satisfactory outcome in such cases.

    A 68-year-old woman, complained of an indolent lump about 60 × 70 mm in size in the left lower back. We conducted a computed tomography scan, which exhibited a hernia of Gerota'sfascia-commonly called superior lumbar hernia. In the right lateral position, the hernia contents were observed to attenuate, hence only closure of the hernial orifice was conducted by using Kugel patch, without removal of the hernia sack. Six months after the surgery, she has had no relapse of the hernia. Superior lumbar hernia, which occurs in an anatomically brittle region in the lower back, is a rare and potentially serious disease. The urologic surgeon should bear in mind this rarely seen entity.

    Single Incision Endoscopic Surgery (SIES) has emerged as a less invasive surgery among laparoscopic surgeries, and this approach for incisional hernia was reported recently. This is the first report of SIES for an incisional lumbar hernia. A 66-year-old Japanese woman was referred to our institution because of a left flank hernia that developed after left iliac crest bone harvesting. A 20-mm incision was created on the left side of the umbilicus and all three trocars (12, 5, and 5 mm) were inserted into the incision. The hernial defect was 14 × 9 cm and was repaired with intraperitoneal onlay mesh and a prosthetic graft. The postoperative course was uneventful. SIES for lumbar hernia offers a safe and effective outcome equivalent compared to laparoscopic surgery. In addition, SIES is less invasive and has a cosmetic benefit.

    Spondylolisthesis with or without spondylolysis is common in the lumbar spine. Associated fracture in the pedicle (`pediculolysis`) is unusual. The margins of pedicular stress fractures, like spondylolysis, usually appear sclerotic. A patient with a pedicular stress fracture with minimal marginal sclerosis suggesting an injury of recent onset is presented here. There was associated bilateral spondylolysis. The findings in this patient suggest that established pediculolysis probably represents a stress fracture that has failed to heal. (authors). 10 refs., 2 figs.

    Epidural analgesia is usually contraindicated in case of infection at the site of needle insertion. Tinea versicolor is a benign superficial cutaneous fungal infection caused by the proliferation of a skin commensal yeast of low pathogenicity. We report the case of a pregnant woman with a tinea versicolor in the lumbar region, who benefited from a labor epidural analgesia, realised with reinforced antiseptic measures. No neurological or infectious complication occurred.

    Full Text Available OBJECTIVE: To integrate patients with lumbar instability in a multisensor platform in the process of assessment and diagnosis, assigning quantitative parameters for the sagittal balance (SB and muscle function. METHODS: Experimental study involving adult patients diagnosed with diseases that cause alterations in the SB, that were or were not submitted to surgery with posterior instrumentation and fusion. Each patient underwent anthropometric measurements in body composition scale; a kinesiological analysis using a multisensor platform consisting of depth camera to static/dynamic analysis for the quantitative measurement of SB, and surface electromyography to capture the level of abdominal and lumbar muscles activation and through flexion and extension. RESULTS: Seven adult patients: five females (62.5%and two men (37.5% with a mean age 48 years. Images with depth cameras resulted in a SB of from -6.4 to +5.3cm (average -5.7cm. In individuals with positive sagittal balance the percentage of activation (PA of the abdominal muscles was 58.5% and the lower back lumbar was 75.25%; patients with negative SB integrated the PA of the abdominal muscles of 70.25% and lumbar of 65%; the patient with neutral SB exhibited activation of the abdominal muscles of 87.75% and lumbar muscles of 78.25%. CONCLUSIONS: We observed a trend towards positive SB in patients with overweight and obesity by BMI, as well as increased activation of the abdominal muscles. The multi sensor platform is a useful tool for the diagnosis and prognosis of diseases involving sagittal imbalance.

    Full Text Available Knowledge of anatomic spinal structures, especially its relation-ship to the functions performed, is necessary to form a correct diagnosis. The anatomical structure of the vertebrae varies de-pending on the level of the spinal segment. Normal anatomical parameters, derived from bone structures of the spine, are roughly determined by X-ray method.This paper presents the results of the survey radiography of the lumbar spine in a straight line and lateral projections in 30 individ-uals without pathology spine, aged 21-60 years with frequently observed lumbar spinal stenosis stenosis. Applying X-ray method there were studied shape, height, and the contours of the vertebral bodies and intervertebral disc in the front (interpedicular and sagittal planes; there were measured dimensions of the lumbar canal and foramen holes in the same planes. Using X-ray method can fully identify the bone parameters of vertebral column. How-ever, the informativity of the method depends on knowledge of radiologist about topographic anatomical features of spine.

    Full Text Available BACKGROUND Amongst painful diseases, sciatica occupies a foremost place by reason of its prevalence, its production by a great variety of conditions, the great disablement it may produce and its tending to relapse all of which have led to its recognition as one of the great scourges of humanity. Intervertebral disc prolapse is the important and common cause of low back pain and sciatica. Here, the subject of laminectomy and discectomy in the treatment of proven intervertebral disc prolapse in the lower lumbar region is reviewed and its results examined. AIM OF STUDY This study was undertaken in order to evaluate the following objectives. PRIMARY Analysis of clinical parameters and per operative findings of lumbar intervertebral disc prolapse. SECONDARY Analysis of clinical parameters and surgical outcome in lumbar intervertebral disc prolapse with respect to improvement in pain and neurological status. MATERIALS AND METHODS The study was undertaken in 22 patients who attended the Orthopaedic Department of Mount Zion Medical College, Adoor, between August 2014 to July 2015. All of them were suffering from a prolapsed lumbar vertebral disc as shown by clinical examination and investigations. Lumbar laminectomy and discectomy constituted the operative procedure for all of them. RESULTS In acute onset cases and cases with short duration, results were good. By six months, 80% of patients recorded of good pain relief, 80% of patients returned to work within six 6 months, 60% of patients showed good neurological recovery by 6 months. Laminectomy and discectomy in proven cases of lumbar intervertebral disc prolapse is a rewarding procedure. LT definitely relieved pain in all cases and improved morbidity and neurological deficits in most of the cases. CONCLUSION 1. Laminectomy and discectomy is an effective method of treatment in herniation of lumbar intervertebral disc. 2. The procedure is ideally done in those with the disc prolapse proved with the

  14. REHABILITATION THERAPY VERSUS DRUG THERAPY IN PATIENTS WITH LUMBAR DISC DEGENERATION

    2013-12-01

    Full Text Available Lumbar disc degeneration is a disorder whose clinical manifestations are represented by episodic pain in the lumbar spine, without lumbar blockage and minor muscle contraction. Because lumbalgia caused by lumbar disc degeneration is not always very high intensity pain, the easiest to apply treatment is drug therapy. The aim of this study was to analyze the potential role of rehabilitation treatment in the recovery of patients and the prevention of complications compared to drug therapy alone. The study included 28 patients (17 women and 11 men aged between 23-60 years, assigned to two groups: 20 patients who received rehabilitation treatment (consisting of massage, kinesiotherapy, hydrokinesiotherapy, electrotherapy and medication and 8 patients who received drug treatment consisting of anti-inflammatory and analgesic drugs. The treatment duration was 10 days. For the evaluation of pain, the visual analogue scale was used, for the degree of disability, the Oswestry questionnaire, and for joint mobility and muscle strength, articular and muscular testing. At the end of treatment, the study group compared to the control group had a statistically significant result for pain (p=0.001, as well as for the Oswestry score (p=0.030. The mean age of the patients was 35.51±3.026, which shows an increased incidence among young adults. A possible connection between the development of the disease in women and age less than 45 years was also investigated, but the result was not statistically significant, p=0.22. Our data suggest the fact that rehabilitation treatment plays an important role in the reduction of pain and the improvement of the quality of life of patients with lumbar disc degeneration by decreasing the degree of disability. In the future, it can be proposed to monitor patients with lumbar disc degeneration over a longer time period in order to see the effects of kinetic rehabilitation programs in relation to the delay of chronicization.

    Here we provide the most extensive metric and morphological analysis performed to date on the Neandertal lumbar spine. Neandertal lumbar vertebrae show differences from modern humans in both the vertebral body and in the neural arch, although not all Neandertal lumbar vertebrae differ from modern humans in the same way. Differences in the vertebral foramen are restricted to the lowermost lumbar vertebrae (L4 and L5), differences in the orientation of the upper articular facets appear in the uppermost lumbar vertebrae (probably in L1 and L2-L3), and differences in the horizontal angle of the transverse process appear in L2-L4. Neandertals, when compared to modern humans, show a smaller degree of lumbar lordosis. Based on a still limited fossil sample, early hominins (australopiths and Homo erectus) had a lumbar lordosis that was similar to but below the mean of modern humans. Here, we hypothesize that from this ancestral degree of lumbar lordosis, the Neandertal lineage decreased their lumbar lordosis and Homo sapiens slightly increased theirs. From a postural point of view, the lower degree of lordosis is related to a more vertical position of the sacrum, which is also positioned more ventrally with respect to the dorsal end of the pelvis. This results in a spino-pelvic alignment that, though different from modern humans, maintained an economic postural equilibrium. Some features, such as a lower degree of lumbar lordosis, were already present in the middle Pleistocene populations ancestral to Neandertals. However, these middle Pleistocene populations do not show the full suite of Neandertal lumbar morphologies, which probably means that the characteristic features of the Neandertal lumbar spine did not arise all at once.

    The goal of this review is to discuss the mechanisms of postural degeneration, particularly the loss of lumbar lordosis commonly observed in the elderly in the context of evolution, mechanical, and biological studies of the human spine and to synthesize recent research findings to clinical management of postural malalignment. Lumbar lordosis is unique to the human spine and is necessary to facilitate our upright posture. However, decreased lumbar lordosis and increased thoracic kyphosis are hallmarks of an aging human spinal column. The unique upright posture and lordotic lumbar curvature of the human spine suggest that an understanding of the evolution of the human spinal column, and the unique anatomical features that support lumbar lordosis may provide insight into spine health and degeneration. Considering evolution of the skeleton in isolation from other scientific studies provides a limited picture for clinicians. The evolution and development of human lumbar lordosis highlight the interdependence of pelvic structure and lumbar lordosis. Studies of fossils of human lineage demonstrate a convergence on the degree of lumbar lordosis and the number of lumbar vertebrae in modern Homo sapiens. Evolution and spine mechanics research show that lumbar lordosis is dictated by pelvic incidence, spinal musculature, vertebral wedging, and disc health. The evolution, mechanics, and biology research all point to the importance of spinal posture and flexibility in supporting optimal health. However, surgical management of postural deformity has focused on restoring posture at the expense of flexibility. It is possible that the need for complex and costly spinal fixation can be eliminated by developing tools for early identification of patients at risk for postural deformities through patient history (genetics, mechanics, and environmental exposure) and tracking postural changes over time.

    A 64-year-old man was referred to the authors with low-back pain (LBP) and right leg pain with a history of previously diagnosed lumbar disc herniation (LDH) at L4-5. He had undergone 2 percutaneous endoscopic lumbar discectomies (PELDs) for the herniation at another institution, and according to the surgical record of the second surgery, a dural tear occurred intraoperatively but was not repaired. Postoperative conservative treatments such as an epidural block and blood patch had not relieved his persistent LBP or right leg pain. Upon referral to the authors, MRI and myelography revealed an intradural LDH. The herniated mass was removed by durotomy, and posterior lumbar interbody fusion was performed. His symptoms were partially improved after surgery. Primary suture is technically difficult when a dural tear occurs during PELD. Therefore, close attention should be paid to avoiding such tears, and surgeons should increase their awareness of intradural LDH as a possible postoperative complication of PELD.

    As spinal surgery in elderly patients is becoming increasingly frequent, comorbidities likely to be decompensated after such procedures must be kept in mind. We report here the case of an 82-year-old woman who presented rapidly progressive spinal cord compression following lumbar surgery for radiculopathy. Investigations showed a thoracic intradural extramedullary compressive lesion, which after removal turned out to be a meningioma. We suggest that radiculopathy and non-specific degenerative modifications partially masked this lesion, and that lumbar surgery caused this acute neurological deterioration. Therefore, we advice caution in older patients among whom such ambiguous clinical presentation is frequent. Copyright © 2013. Published by Elsevier Masson SAS.

    Study Design Case report. Objective Lumbar juxtafacet cysts (synovial and ganglion cysts) are a rare cause of low back and radicular leg pain. Most patients with lumbar cysts are in their sixth decade of life and have significant facet joint and disk degeneration. Lumbar synovial cysts (LSCs) are extremely rare in adolescence and young adulthood, and to our knowledge, only two pediatric cases of LSC have been reported in the literature. We aim to prove the existence of LSC in adolescent patients as a real entity that causes low back and radicular complaints and to discuss the possibility of traumatic injury as a pathogenic cause of LSC formation in adolescence. A case of an 18-year old patient with LSC is presented. We report the clinical presentation, management, outcome, and review of the literature, focusing on issues that remain debatable. Methods The case is presented together with its clinical course, the diagnostic techniques, the surgical findings, histologic results, and the treatment outcome. Results After surgical treatment, the patient's complaints were alleviated and almost no complaints were registered during the next 6 months' follow-up. Conclusions LSCs are extremely rare in adolescence, but they could be considered in the differential diagnosis in adolescent patients with low back pain and radiculopathy. Surgical removal of LSC could be considered as a treatment option to provide immediate and safe symptomatic relief.

    Obesity causes sympathetic activation that promotes atherosclerosis, end-organ damage, and hypertension. Because high-fat induced weight gain in rats elevates plasma leptin at 1–3 days following onset of calorie dense diets, we hypothesized that diet-induced overfeeding will increase sympathetic activity within one week following onset of the regimen. To test this, we continuously measured sympathetic activity and blood pressure before and during the onset of diet-induced obesity using a high calorie cafeteria-style diet. Female Wistar rats, in which radiotelemeters had been implanted for continuous monitoring of lumbar sympathetic activity, mean arterial pressure, and heart rate, were randomly assigned to groups that received regular chow (control) or a cafeteria diet for a period of 15 days. This short-term cafeteria-feeding regimen caused modest but non-significant increases in body weight (P = 0.07) and a doubling of brown and white adipose tissue (P cafeteria rats compared with controls (P Cafeteria diet-induced weight gain caused increases in lumbar sympathetic nerve activity that became significant by the 12th day of the diet (p cafeteria-style diet stimulates sustained increases in lumbar sympathetic neural drive in rats.

    L4–L5 traumatic spondylolisthesis has been rarely reported in the literature. At lumbar spine level traumatic dislocation lesion realizes“traumatic spondylolisthesis or traumatic bilateral lumbar facet locked syndrome”. The aim of the present paper is to report this rare lesion and discuss its mechanism and management. A case report is followed by Literature review made on Medline and scholar google database from 2000 to 2015. The case report concerned a 33-year-old man, who refused to wear a seat belt, injured his lumbar spine following a motor vehicle accident. L4-L5 spondylolisthesis occurred after the vehicle rolled over several times. Sixteen months after the accident the patient had a favorable outcome. Literature review on Medline and scholar google database from 2000 to 2015 was carried out and five cases of traumatic spondylolisthesis were found. The Sex ratio was 3/2. Surgical treatment consisted of posterolateral interbody fusion. Traumatic lumbar spine spondylolisthesis is rare. When it occurs, it is always associated with vertebral lumbar fracture. L4-L5 traumatic spondylolisthesis was caused by a high-energy mechanism and improper use of seat belt.

    Lumbar surgery is regularly applied in cases of discal hernia and acquired lumbar stenosis. In this report, we present a case of a laceration in the left common iliac artery and iliac vein during a lumbar surgery and discuss the literature concerning this kind of event. In the present case, the surgical procedure was followed by a sudden decrease in blood pressure, and the surgeon discovered an intra-abdominal haemorrhage that led to the patient's death. Postmortem investigation confirmed the intra-abdominal haemorrhage and revealed a laceration of the proximal portion of the left common iliac artery and left iliac vein. The source of bleeding could be detected especially thanks to multi-phase postmortem CT angiography (MPMCTA), which was performed prior to autopsy. We also found a haemorrhagic path through the intervertebral disc between the L4-L5 vertebrae, caused by the surgeon's instrument (pituitary rongeur). To date, a few cases have been described of iatrogenic death resulting from a tear in the iliac vessels during lumbar surgery, but not from the postmortem perspective. Such investigations have recently been modernized thanks to the introduction of forensic imaging. In particular, MPMCTA offers new possibilities in postmortem investigations and can be considered the new gold standard for investigating deaths related to medical intervention. Here we describe the first case of a death during lumbar surgery using this new method.

    To assess and characterize the sacrum angular displacements in response to lumbar lordosis after lumbar/lumbosacral fusion. A finite element model of the lower lumbar spine-pelvis was established and used to simulate the posterior fusion at L3-L5 and L4-S1. The lordosis angle in the fusion segments was set to five different conditions with respect to the intact model: 10° less than intact, 5° less than intact, same as intact, 5° more than intact, and 10° more than intact. Variations of the sacrum angular displacements with lordosis changes were analyzed under loading setting of axial compression, flexion, extension, lateral bending, and axial rotation. Compared with the intact lordosis, both increased and decreased lumbar lordosis angles caused the sacrum angular displacements to be increased. The lordosis angle increased by 10° induced the most substantial increase in sacrum angular displacements. In addition, the sacrum angular displacements of the L4-S1 fusion model at different lordosis angles were higher than those of the L3-L5 fusion model. The sacrum angular displacements occur as a result of the fusion surgery (L4-S1) and the changes in lumbar lordosis.

    Study Design A retrospective cohort study. Objectives To determine the outcome and any differences in the clinical results of three different surgical methods for lumbar disk herniation and to assess the effect of factors that could predict the outcome of surgery. Methods We evaluated 148 patients who had operations for lumbar disk herniation from March 2006 to March 2011 using three different surgical techniques (laminectomy, microscopically assisted percutaneous nucleotomy, and spinous process osteotomy) by using Japanese Orthopaedic Association (JOA) Back Pain Evaluation Questionnaire, Resumption of Activities of Daily Living scale and changes of visual analog scale (VAS) for low back pain and radicular pain. Our study questionnaire addressed patient subjective satisfaction with the operation, residual complaints, and job resumption. Data were analyzed with SPSS version 16.0 (SPSS, Inc., Chicago, Illinois, United States). Statistical significance was set at 0.05. For statistical analysis, chi-square test, Mann-Whitney U test, Kruskal-Wallis test, and repeated measure analysis were performed. For determining the confounding factors, univariate analysis by chi-square test was used and followed by logistic regression analysis. Results Ninety-four percent of our patients were satisfied with the results of their surgeries. VAS documented an overall 93.3% success rate for reduction of radicular pain. Laminectomy resulted in better outcome in terms of JOA Back Pain Evaluation Questionnaire. The outcome of surgery did not significantly differ by age, sex, level of education, preoperative VAS for back, preoperative VAS for radicular pain, return to previous job, or level of herniation. Conclusion Surgery for lumbar disk herniation is effective in reducing radicular pain (93.4%). All three surgical approaches resulted in significant decrease in preoperative radicular pain and low back pain, but intergroup variation in the outcome was not achieved. As indicated

    Despite the interest in lumbar spinous process (SP)-based surgical innovation, there are no large published studies that have characterized the morphometry of lumbar SPs. To provide accurate level-specific morphometric data with respect to human lumbar SPs using a human cadaveric lumbar spine model and to describe the morphometric variation of lumbar SPs with respect to gender, race, and age. An anatomic observational study. This study used 2,955 cadaveric lumbar vertebrae from 591 adult spines at the Hamann-Todd Human Osteological Collection. Specimens were aged 20 to 79 years. Each vertebra was photographed in standardized positions and measured using ImageJ software. Direct measurements were made for the SP length, width, height, slope, and caudal morphology. Gender, race, and age were recorded and analyzed. Spinous process length was 24.8±4.6 mm (L5) to 33.9±3.9 mm (L3). Effective length varied from 19.5±2.6 mm (L1) to 24.6±3.3 mm (L4). Height was shortest at L5 (18.2±2.7 mm). Caudal width was greater than the cranial width. Slope, caudal morphology, and radius measures showed large interspecimen variation. Slope at L5 was steeper than other levels (23.7°±10.5°, p<.0001). Most specimens demonstrated convex caudal morphology. L4 had the highest proportion of convexity (80.7%). L1 was the only level with predominantly concave morphology. Measurements for female SPs were smaller, but the slope was steeper. Anatomic and effective SP lengths were longer for specimens from white individuals. Specimens from black individuals had larger width and height, as well as steeper slope. Black specimens had more convex morphology at L4 and L5. With increasing age, the SP length, effective length, and width increased. Height increased with age only at L4 and L5. Slope and caudal radius of curvature decreased with age, and increasingly convex morphology was noted at most levels. This large cadaveric study provides level-specific morphometric data regarding the osseous

    [Purpose] This study investigated the effect of stretching with lumbar traction on VAS and Oswestry scale scores of lumbar 4-5 herniated intervertebral disc (HIVD) patients. [Subjects] We recruited 20 lumbar 4-5 HIVD patients. [Methods] We performed stretching with lumbar traction for lumbar 4-5 HIVD patients during 4 weeks. The VAS and Oswestry scales were measured before and 4 weeks after the intervention. [Results] The results showed a significant decrease in VAS scale scores for stretching with lumbar traction in lumbar 4-5 HIVD patients, from 18±1.29 to 2.1±1.35. The Oswestry scale scores also decreased significantly, from 20.35±2.01 to 3.5±2.84, after stretching with lumbar traction. [Conclusion] Thus, we suggest stretching with lumbar traction for lumbar 4-5 HIVD patients.

  12. Regression of lumbar disk herniation

    Full Text Available Compression of the spinal nerve root, giving rise to pain and sensory and motor disorders in the area of its innervation is the most vivid manifestation of herniated intervertebral disk. Different treatment modalities, including neurosurgery, for evolving these conditions are discussed. There has been recent evidence that spontaneous regression of disk herniation can regress. The paper describes a female patient with large lateralized disc extrusion that has caused compression of the nerve root S1, leading to obvious myotonic and radicular syndrome. Magnetic resonance imaging has shown that the clinical manifestations of discogenic radiculopathy, as well myotonic syndrome and morphological changes completely regressed 8 months later. The likely mechanism is inflammation-induced resorption of a large herniated disk fragment, which agrees with the data available in the literature. A decision to perform neurosurgery for which the patient had indications was made during her first consultation. After regression of discogenic radiculopathy, there was only moderate pain caused by musculoskeletal diseases (facet syndrome, piriformis syndrome that were successfully eliminated by minimally invasive techniques.

    In a longitudinal study, the dose-response relationships between long term occupational exposure to whole-body vibration and degenerative processes in the lumbar spine caused by the lumbar disks were examined. From 1990 to 1992, 388 vibration-exposed workers from different driving jobs were examined medically and by lumbar X-ray. For each individual, a history of all exposure conditions was recorded, and a cumulative vibration dose was calculated allowing comparisons between groups of low, middle, and high intensity of exposure. 310 subjects were selected for a follow-up four years later, of whom 90·6% (n=281) agreed to participate. In comparing the exposure groups, the results indicate that the limit value ofazw(8h)=0·8 m/s2should be reviewed. The best fit between the lifelong vibration dose and the occurrence of a lumbar syndrome was obtained by applying a daily reference ofazw(8h)=0·6 ms2as a limit value. The results became more distinct still when only those subjects were included in the statistical analysis who had had no lumbar symptoms up to the end of the first year of exposure. The prevalence of lumbar syndrome is 1·55 times higher in the highly exposed group when compared to the reference group with low exposure (CI95%=1·24/1·95). Calculating the cumulative incidence of new cases of lumbar syndrome in the follow-up period yields a relative risk ofRRMH=1·37 (CI95%=0·86/2·17) for the highly exposed group. It is concluded that the limit value for the calculation of an individual lifelong vibration dose should be based on a daily reference exposure ofazw(8h)=0·6 m/s2. With increasing dose it is more and more probable that cases of lumbar syndrome are caused by exposure to vibration.

    Objective. The goal of the present study was to examine the clinical results of percutaneous endoscopic lumbar discectomy (PELD) and open lumbar surgery for patients with adjacent segment degeneration (ASD) and recurrence of disc herniation. Methods. From December 2011 to November 2013, we collected forty-three patients who underwent repeated lumbar surgery. These patients, either received PELD (18 patients) or repeated open lumbar surgery (25 patients), due to ASD or recurrence of disc herniation at L3-4, L4-5, or L5-S1 level, were assigned to different groups according to the surgical approaches. Clinical data were assessed and compared. Results. Mean blood loss was significantly less in the PELD group as compared to the open lumbar surgery group (P < 0.0001). Hospital stay and mean operating time were shorter significantly in the PELD group as compared to the open lumbar surgery group (P < 0.0001). Immediate postoperative pain improvement in VAS was 3.5 in the PELD group and -0.56 in the open lumbar surgery group (P < 0.0001). Conclusion. For ASD and recurrent lumbar disc herniation, PELD had more advantages over open lumbar surgery in terms of reduced blood loss, shorter hospital stay, operating time, fewer complications, and less postoperative discomfort.

    Low back pain is a significant problem and its cost is enormous to society. However, diagnosis of the underlying causes remains problematic despite extensive study. Reasons for this arise from the deep-rooted situation of the spine and also from its structural complexity. Clinicians have to mentally convert 2-D image information into a 3-D form to gain a better understanding of structural integrity. Therefore, visualisation and animation may be helpful for understanding, diagnosis and for guiding therapy. Some low back pain originates from mechanical disorders, and study of the spine kinematics may provide an insight into the source of the problem. Digital videofluoroscopy was used in this study to provide 2-D image sequences of the spine in motion, but the images often suffer due to noise, exacerbated by the very low radiation dosage. Thus determining vertebrae position within the image sequence presents a considerable challenge. This paper describes a combination of spine kinematic measurements with a solid model of the human lumbar spine for visualisation of spine motion. Since determination of the spine kinematics provides the foundation and vertebral extraction is at the core, this is discussed in detail. Edge detection is a key feature of segmentation and it is shown that phase congruency performs better than most established methods with the rather low-grade image sequences from fluoroscopy. The Hough transform is then applied to determine the positions of vertebrae in each frame of a motion sequence. In the Hough transform, Fourier descriptors are used to represent the vertebral shapes. The results show that the Hough transform is a very promising technique for vertebral extraction from videofluoroscopic images. A dynamic visualisation package has been developed in order to view the moving lumbar spine from any angle and viewpoint. Wire frame models of the vertebrae were built by using CT images from the Visible Human Project and these models are scaled to

    The relationship between form and function in the lumbar vertebral column has been well documented among platyrrhines and especially catarrhines, while functional studies of postcranial morphology among strepsirrhines have concentrated predominantly on the limbs. This morphometric study investigates biomechanically relevant attributes of the lumbar vertebral morphology of 20 species of extant strepsirrhines. With this extensive sample, our goal is to address the influence of positional behavior on lumbar vertebral form while also assessing the effects of body size and phylogenetic history. The results reveal distinctions in lumbar vertebral morphology among strepsirrhines in functional association with their habitual postures and primary locomotor behaviors. In general, strepsirrhines that emphasize pronograde posture and quadrupedal locomotion combined with leaping (from a pronograde position) have the relatively longest lumbar regions and lumbar vertebral bodies, features promoting sagittal spinal flexibility. Indrids and galagonids that rely primarily on vertical clinging and leaping with orthograde posture share a relatively short (i.e., stable and resistant to bending) lumbar region, although the length of individual lumbar vertebral bodies varies phylogenetically and possibly allometrically. The other two vertical clingers and leapers, Hapalemur and Lepilemur, more closely resemble the pronograde, quadrupedal taxa. The specialized, suspensory lorids have relatively short lumbar regions as well, but the lengths of their lumbar regions are influenced by body size, and Arctocebus has dramatically longer vertebral bodies than do the other lorids. Lumbar morphology among galagonids appears to reflect a strong phylogenetic signal superimposed on a functional one. In general, relative length of the spinous processes follows a positively allometric trend, although lorids (especially the larger-bodied forms) have relatively short spinous processes for their body size

    Full Text Available Abstract Background Lumbar spinal stenosis is one of the most common causes of low back pain among older adults and can cause significant disability. Despite its prevalence, treatment of spinal stenosis symptoms remains controversial. Epidural steroid injections are used with increasing frequency as a less invasive, potentially safer, and more cost-effective treatment than surgery. However, there is a lack of data to judge the effectiveness and safety of epidural steroid injections for spinal stenosis. We describe our prospective, double-blind, randomized controlled trial that tests the hypothesis that epidural injections with steroids plus local anesthetic are more effective than epidural injections of local anesthetic alone in improving pain and function among older adults with lumbar spinal stenosis. Methods We will recruit up to 400 patients with lumbar central canal spinal stenosis from at least 9 clinical sites over 2 years. Patients with spinal instability who require surgical fusion, a history of prior lumbar surgery, or prior epidural steroid injection within the past 6 months are excluded. Participants are randomly assigned to receive either ESI with local anesthetic or the control intervention (epidural injections with local anesthetic alone. Subjects receive up to 2 injections prior to the primary endpoint at 6 weeks, at which time they may choose to crossover to the other intervention. Participants complete validated, standardized measures of pain, functional disability, and health-related quality of life at baseline and at 3 weeks, 6 weeks, and 3, 6, and 12 months after randomization. The primary outcomes are Roland-Morris Disability Questionnaire and a numerical rating scale measure of pain intensity at 6 weeks. In order to better understand their safety, we also measure cortisol, HbA1c, fasting blood glucose, weight, and blood pressure at baseline, and at 3 and 6 weeks post-injection. We also obtain data on resource utilization

    congenitally lengthened, induced mechanically, or both. Several small muscles are attached to the 12th ribs. We focus attention here on the largest of these muscles namely, QL. It has attachments to the pelvis, 12th ribs and transverse processes of lumbar vertebrae as origins and as insertions. Given increased muscle activity on the lumbar curve convexity and similar to the interpretations of earlier workers outlined above, we suggest two hypotheses, relatively increased activity of the right QL muscle causes the LLCs (first hypothesis; or counteracts the lumbar curvature as part of the body’s attempt to compensate for the curvature (second hypothesis. These hypotheses may be tested by electrical stimulation studies of QL muscles in subjects with lumbar IS by revealing respectively curve worsening or correction. We suggest that one mechanism leading to relatively increased length of the right 12 ribs is mechanotransduction in accordance with Wolff’s and Pauwels Laws.

    Monosynaptic excitatory postsynaptic potentials (EPSPs) evoked by stimulating ipsilateral ventrolateral column (VLC) in the thoracic section were recorded in lumbar motoneurons within the isolated spinal cord of the frog Rana ridibunda. Bath application of the selective GABAB receptor agonist (-)-baclofen (0.05 mM) caused a reduction in the peak amplitude of VLC EPSP. Baclofen did not cause any consistent change in the membrane potential or in the EPSP waveform within frog motoneurones. The selective GABA(B) receptor antagonist saclofen (0.1 mM) completely blocked the effect of (-)-baclofen on VLC EPSP. A decrease in VLC EPSP peak amplitude was also observed during GABA (0.5 mM) application. Unlike (-)-baclofen, inhibition of VLC EPSP induced by GABA was accompanied by a shortening of the EPSP time course and a reduction in membrane input resistance within lumbar motoneurons. The decrease in VLC EPSP peak amplitude induced by (-)-baclofen and GABA was accompanied by an increase in the paired-pulse facilitation. These data provide evidence for a dual pre- and postsynaptic GABAergic inhibition of the VLC monosynaptic EPSP in lumbar motoneurons within the frog spinal cord.

    [Purpose] To investigate the effects of movement from a postural maintenance position on lumbar hemodynamic changes, in order to prevent lower back pain and develop exercise therapy. [Subjects and Methods] Twenty-five healthy adults (mean age: 23.2 years) participated in the study. During flexion-extension exercise, the subjects moved their trunks gradually to a flexed position from an upright posture while sitting and standing, and then returned to and maintained an upright (re-upright) position. In the extension-flexion exercise, the subjects moved their trunks gradually from an upright posture to an extended position, and back while maintaining an upright (re-upright) position. Lumbar spinal muscle activity and hemodynamic changes were evaluated during both exercises. [Results] During the flexion and extension exercises, increased trunk-flexion angle caused increased muscle activity, decreased oxygenated hemoglobin in the multifidus muscle, and increased deoxygenated hemoglobin in the multifidus and lumbar erector spinae muscles. Moreover, the muscle activities were nearly the same in the re-upright and upright positions, and total hemoglobin also increased. [Conclusion] In both standing and sitting positions, holding the trunk in a flexed position causes ischemic hemodynamic changes in the multifidus muscle; however, the hyperemic response when returning the trunk to an extended position may improve circulation.

    Lumbar vertebral fractures vary greatly in types and causes and usually result from severe trauma or pathological conditions such as osteoporosis. Lumbar wedge compression fractures are amongst the most common ones where the vertebra is severely compressed forming a wedge shape and causing pain and pressure on the nerve roots and the spine. Since vertebral segmentation is the first step in any automated diagnosis task, we present a fully automated method for robustly localizing and segmenting the vertebrae for preparation of vertebral fracture diagnosis. Our segmentation method consists of five main steps towards the CAD(Computer-Aided Diagnosis) system: 1) Localization of the intervertebral discs. 2) Localization of the vertebral skeleton. 3) Segmentation of the individual vertebra. 4) Detection of the vertebrae center line and 5) Detection of the vertebrae major boundary points. Our segmentation results are promising with an average error of 1.5mm (modified Hausdorff distance metric) on 50 clinical CT cases i.e. a total of 250 lumbar vertebrae. We also present promising preliminary results for automatic wedge compression fracture diagnosis on 15 cases, 7 of which have one or more vertebral compression fracture, and obtain an accuracy of 97.33%.

    Full Text Available Fusion and rigid instrumentation have been currently the mainstay for the surgical treatment of degenerative diseases of the spine over the last 4 decades. In all over the world the common experience was formed about fusion surgery. Satisfactory results of lumbar spinal fusion appeared completely incompatible and unfavorable within years. Rigid spinal implants along with fusion cause increased stresses of the adjacent segments and have some important disadvantages such as donor site morbidity including pain, wound problems, infections because of longer operating time, pseudarthrosis, and fatigue failure of implants. Alternative spinal implants were developed with time on unsatisfactory outcomes of rigid internal fixation along with fusion. Motion preservation devices which include both anterior and posterior dynamic stabilization are designed and used especially in the last two decades. This paper evaluates the dynamic stabilization of the lumbar spine and talks about chronologically some novel dynamic stabilization devices and thier efficacies.

    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.

    Spinal fusion at the L4-5 disc space alters the normal biomechanics of the spine, and the loss of motion at the fused level is compensated by increased motion and load at the other unfused segments. This may lead to deterioration of the adjacent segments of the lumbar spine, called adjacent-segment disease (ASD). In this study, the authors investigate the distracted disc height of the fused segment, caused by cage or bone insertion during surgery, as a novel risk factor for ASD after posterior lumbar interbody fusion (PLIF). Radiographic L3-4 ASD is defined by development of spondylolisthesis greater than 3 mm, a decrease in disc height of more than 3 mm, or intervertebral angle at flexion smaller than -5 degrees . Symptomatic ASD is defined by a decrease of 4 points or more on the Japanese Orthopaedic Association scale. Eighty-five patients with L-4 spondylolisthesis treated by L4-5 PLIF underwent follow-up for more than 2 years (mean 38.8 +/- 17.1 months). The patients were divided into 3 groups according to the final outcome. Group A comprised those patients without ASD (58), Group B patients had radiographic ASD (14), and Group C patients had symptomatic ASD (13). The L4-5 disc space distraction by cage insertion was 3.1 mm in the group without ASD, 4.4 mm in the group with radiographic ASD, and 6.2 mm in the group with symptomatic ASD, as measured using lateral spinal radiographs just after surgery. Multivariate analysis showed that distraction was the most significant risk factor. The excessive distraction of the L4-5 disc space during PLIF surgery is a significant and potentially avoidable risk factor for the development of radiographic, symptomatic ASD.

    This study aimed at deriving a lordosis predictive equation using the pelvic incidence and to establish a simple prediction method of lumbar lordosis for planning lumbar corrective surgery in Asians. Eighty-six asymptomatic volunteers were enrolled in the study. The maximal lumbar lordosis (MLL), lower lumbar lordosis (LLL), pelvic incidence (PI), and sacral slope (SS) were measured. The correlations between the parameters were analyzed using Pearson correlation analysis. Predictive equations of lumbar lordosis through simple regression analysis of the parameters and simple predictive values of lumbar lordosis using PI were derived. The PI strongly correlated with the SS (r = 0.78), and a strong correlation was found between the SS and LLL (r = 0.89), and between the SS and MLL (r = 0.83). Based on these correlations, the predictive equations of lumbar lordosis were found (SS = 0.80 + 0.74 PI (r = 0.78, R (2) = 0.61), LLL = 5.20 + 0.87 SS (r = 0.89, R (2) = 0.80), MLL = 17.41 + 0.96 SS (r = 0.83, R (2) = 0.68). When PI was between 30° to 35°, 40° to 50° and 55° to 60°, the equations predicted that MLL would be PI + 10°, PI + 5° and PI, and LLL would be PI - 5°, PI - 10° and PI - 15°, respectively. This simple calculation method can provide a more appropriate and simpler prediction of lumbar lordosis for Asian populations. The prediction of lumbar lordosis should be used as a reference for surgeons planning to restore the lumbar lordosis in lumbar corrective surgery.

    Magnetic resonance (MR) imaging has been performed in consecutive 114 patients with a chief complaint of lumbar pain. A retrospective review of MR images of a total of 570 lumbar vertebrae from these patients were done to examine lumbar disc degeneration. According to the MR intensity of nucleus pulposus on T2-wighted sagittal images, lumbar disc degeneration was graded on a scale of 0-4: 0=uniform hyperintensity; 1=slight hypointensity; 2=centrally band-like hypointensity with marginal hyperintensity; 3=irregular hypointensity in both the central and marginal sites; 4=uniform hypointensity. Lumbar disc degeneration was observed in 76%; and it was rapidly increased in frequency in the 30 or older age groups. Of 570 vertebrae, 51 (8.9%) had narrowing of intervertebral cavity. For these vertebrae, a mean score of lumbar disc degeneration was 3.1. Lumbar disc herniation was seen in 93 vertebrae, with a mean score of lumbar disc degeneration being 3.07. Changes in vertebral body marrow were seen in 14 vertebrae (2.5%), in which a mean score of intervertebral disc degeneration was 3.71. (N.K.).

    To evaluate the radiographic results of minimally invasive (MIS) anterior lumbar interbody fusion (ALIF) and transforaminal lumbar interbody fusion (TLIF). Twelve and nineteen patients who underwent MIS-ALIF, MIS-TLIF, respectively, from 2006 to 2008 were analyzed with a minimum 24-months' follow-up. Additionally, 18 patients treated with single level open TLIF surgery in 2007 were evaluated as a comparative group. X-rays and CT images were evaluated preoperatively, postoperatively, and at the final follow-up. Fusion and subsidence rates were determined, and radiographic parameters, including lumbar lordosis angle (LLA), fused segment angle (FSA), sacral slope angle (SSA), disc height (DH), and foraminal height (FH), were analyzed. These parameters were also compared between the open and MIS-TLIF groups. In the MIS interbody fusion group, statistically significant increases were observed in LLA, FSA, and DH and FH between preoperative and final values. The changes in LLA, FSA, and DH were significantly increased in the MIS-ALIF group compared with the MIS-TLIF group, but SSA and FH were not significantly different. No significant differences were seen between open and MIS-TLIF except for DH. The interbody subsidence and fusion rates of the MIS groups were 12.0±4% and 96%, respectively. Radiographic results of MIS interbody fusion surgery are as favorable as those with conventional surgery regarding fusion, restoration of disc height, foraminal height, and lumbar lordosis. MIS-ALIF is more effective than MIS-TLIF for intervertebral disc height restoration and lumbar lordosis.

    Abstract The purpose of our study is to evaluate sagittal parameters in 2-level lumbar degenerative spondylolisthesis (DS) (TLDS). A total of 15 patients with TLDS, 40 patients with single-level DS (SLDS), and 30 normal volunteers as control were included in our study. All subjects performed on full spine X-ray. Two categorized data were analyzed: patient characteristics—age, sex, body mass index, radiographic parameters-pelvic incidence (PI), pelvic tilt (PT), lumbar lordosis (LL), sacral slope (SS), PI–LL, Cobb between the fifth thoracic vertebral and 12th thoracic vertebral (T5–T12), sagittal vertical axis (SVA) Cobb angle of spondylolisthesis level (CSL), ratio of PT to SS (PT/SS), CSL/LL, variation trend of SS over PI, and LL over PI. The PI (73.1° vs 52.9°), SS (50.8° vs 32.2°), LL (53.1° vs 46.9°), SVA (66.1 vs 22.0 mm), PI–LL (20.0° vs 6.0°), and CSL (23.6° vs 20.0°) in TLDS were significantly larger than these in SLDS. The PI (73.1° vs 40.6°), PT (22.3° vs 17.1°), SS (50.8° vs 23.5°), LL (53.1° vs 32.5°), PI–LL (20.0° vs 8.1°), and SVA (66.1 vs 17.0 mm) in TLDS were significantly larger than those in the normal group (NG). The PI (52.9° vs 40.6°), PT (21.0° vs 17.1°), SS (32.2° vs 23.5°), LL (46.9° vs 32.5°), and SVA (22.0 vs 17.0 mm) in SLDS were significantly higher than those in NG. However, PT/SS (44.0%), LL over PI (y = 0.39x + 24.25), SS over PI (y = 10.79 + 0.55x) were lower in TLDS than these in SLDS (63.8%, y = 0.41x + 25, y = 0.65x − 2.09, respectively), and the similar tend between SLDS and NG (74.0%, y = 0.49x + 13.09, y = 0.67x − 3.9, respectively). Our results showed that 2-level lumbar DS, which was caused by multiple-factors, has a severe sagittal imbalance, but single-level has not any. When we plan for surgical selection for 2-level lumbar DS, global sagittal balance must be considered. PMID:27977581

    During pregnancy approximately 50% of women suffer from low back pain (LBP), which significantly affects their everyday life. The pain could result in chronic insomnia, limit the pregnant women in their ability to work and produce a reduction of their physical activity. The etiology of the pain is still critically discussed and not entirely understood. In the literature different explanations for LBP are given and one of the most common reasons is the anatomical changes of the female body during pregnancy; for instance, there is an increase in the sagittal moments because of the enlarged uterus and fetus and the occurrence of hyperlordosis.The aim of this study was to describe how the anatomical changes in pregnant women affect the stability and the moments acting on the lumbar spine with the help of a simplified musculoskeletal model.A two-dimensional musculoskeletal model of the lumbar spine in the sagittal plane consisting of five lumbar vertebrae was developed. The model included five centres of rotation and three antagonistic pairs of paraspinal muscles. The concept of altered acting torques during pregnancy was explored by varying the geometrical arrangements. The situations non-pregnant, pregnant and pregnant with hyperlordosis were considered for the model-based approach. These simulations were done dependent on the stability of the erect posture and local countertorques of every lumbar segment.In spite of the simplicity of the model and the musculoskeletal arrangement it was possible to maintain equilibrium of the erect posture at every lumbar spinal segment with one minimum physiological cross-sectional area of all paraspinal muscles. The stability of the musculoskeletal system depends on the muscular activity of the paraspinal muscles and diminishing the muscular activity causes unstable lumbar segments.The relationship between the non-pregnant and the pregnant simulations demonstrated a considerable increase of acting segmental countertorques

    We evaluated the fractures of the lumbar and sacral vertebral limbus by disc impingement at the peripheral ring apophysis in 23 adults associated with trauma in 16 of them. Lumbalgia, radicular pain and narrow canal symptoms are the presenting forms of this underdiagnosed pathology. CT is the best method of examination, while plain roentgenograms and MR are usually negative. Accurate diagnosis and surgical technique with larger exposure are needed to resect the fractured fragments and protruded disc material for decompressing the roots and the dural sac. Our results were very good on the majority of cases.

    Avoiding exposure of extremities to cold combined with pharmacologic treatment usually suffice in the attempt to suppress the related symptoms of Raynaud's syndrome. This case report describes a severe case of Raynaud's syndrome affecting the lower extremities of a 16-year-old female. She was referred to a centre of vascular surgery with severe vasospasms of the feet. After failed attempts of pharmacologic treatment, a laparoscopic lumbar sympathectomy was performed with no complications and a slight reduction of symptoms three years post-surgically.

    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.

    PurposeTo describe the radiologic findings and imaging response of hepatocellular carcinoma (HCC) supplied by the lumbar artery.MethodsBetween April 2004 and December 2012, we encountered HCC supplied by a lumbar artery in 21 patients. Two investigators retrospectively reviewed clinical and radiological findings of HCC supplied by the lumbar artery using computed tomography (CT) scans and digital subtraction angiograms.ResultsPatients had received 1–27 sessions of previous chemoembolization procedures (mean 7.7 sessions, median 4 sessions). Mean tumor size was 5.3 cm. The locations of HCC supplied by lumbar artery were the bare area (n = 14, 67 %) and segment VI (n = 7, 33 %). Tumor-feeding arteries arose from the main lumbar artery (n = 7), proximal anterior division (n = 4), and distal anterior division (n = 14). In 20 patients, selective chemoembolization through the tumor-feeding arteries of the lumbar artery was achieved. In 1 patient, nonselective embolization at the main lumbar artery was performed. There was no complication such as skin necrosis or paralysis. On the first follow-up enhanced CT scan, target tumors fed by the lumbar artery showed complete response (n = 6), partial response (n = 4), stable disease (n = 3), and progressive disease (n = 8), but overall tumor response was partial response (n = 1) and progressive disease (n = 20).ConclusionWhen HCC is located in the inferior tip or bare area of the liver, a lumbar artery may supply the tumor. Although selective chemoembolization via the tumor-feeding vessel of the lumbar artery can be achieved in most cases, overall tumor response is commonly unfavorable.

    Full Text Available STUDY DESIGN: Meta-analysis. BACKGROUND: Bilateral pedicle screw fixation (PS after lumbar interbody fusion is a widely accepted method of managing various spinal diseases. Recently, unilateral PS fixation has been reported as effective as bilateral PS fixation. This meta-analysis aimed to comparatively assess the efficacy and safety of unilateral PS fixation and bilateral PS fixation in the minimally invasive (MIS lumbar interbody fusion for one-level degenerative lumbar spine disease. METHODS: MEDLINE/PubMed, EMBASE, BIOSIS Previews, and Cochrane Library were searched through March 30, 2014. Randomized controlled trials (RCTs and controlled clinical trials (CCTs on unilateral versus bilateral PS fixation in MIS lumbar interbody fusion that met the inclusion criteria and the methodological quality standard were retrieved and reviewed. Data on participant characteristics, interventions, follow-up period, and outcomes were extracted from the included studies and analyzed by Review Manager 5.2. RESULTS: Six studies (5 RCTs and 1 CCT involving 298 patients were selected. There were no significant differences between unilateral and bilateral PS fixation procedures in fusion rate, complications, visual analogue score (VAS for leg pain, VAS for back pain, Oswestry disability index (ODI. Both fixation procedures had similar length of hospital stay (MD = 0.38, 95% CI = -0.83 to 1.58; P = 0.54. In contrast, bilateral PS fixation was associated with significantly more intra-operative blood loss (P = 0.002 and significantly longer operation time (P = 0.02 as compared with unilateral PS fixation. CONCLUSIONS: Unilateral PS fixation appears as effective and safe as bilateral PS fixation in MIS lumbar interbody fusion but requires less operative time and causes less blood loss, thus offering a simple alternative approach for one-level lumbar degenerative disease.

    AIM To determine the role of cartilage oligomeric matrix protein (COMP), interleukin (IL)-6, IL-10 and ratio of IL-6/IL-10 as risk factors of symptomatic lumbar osteoarthritis (OA) in postmenopausal women with estrogen deficiency. METHODS Case-control study had been conducted in Sanglah General Hospital from October 2015 until March 2016. The blood samples were obtained and analyzed by enzyme-linked immunosorbent assay (ELISA). RESULTS From 44 pairs of samples which divided into 44 samples as case group and 44 samples as control group showed that high level of COMP in estrogen deficiency postmenopausal women were not at risk (OR = 0.7; 95%CI: 0.261-1.751; P = 0.393) for symptomatic lumbar OA (cut-off point 0.946). Estrogen deficiency in postmenopausal women with the high level of IL-6 had 2.7 times risk (OR = 2.7; 95%CI: 0.991-8.320; P = 0.033) for symptomatic lumbar OA from the low level of IL-6 (cut-off point 2.264). At lower level of IL-10, there was no risk for symptomatic lumbar OA (OR = 0.6; 95%CI: 0.209-1.798; P = 0.345) than with the higher level of IL-10 (cut-off point 6.049). While the high ratio of IL-6/IL-10 level in estrogen deficiency postmenopausal women gave 3.4 times risk (OR = 3.4; 95%CI: 1.204-11.787; P = 0.011) for symptomatic lumbar OA than the low ratio of IL-6/IL-10 level (cut-off point 0.364). CONCLUSION High ratio of IL-6/IL-10 plasma level was the highest risk factor for causing symptomatic lumbar OA in postmenopausal women with estrogen deficiency. PMID:28251065

    Full Text Available Lumbar intervertebral discopathy is a common clinical problem and a significant cause of low back pain. Usually it is associated with overload and damage to the intervertebral disc, which directly relates to the instability of the motion segment. Renal normal anatomy between tissues within the spinal canal is a cause of the reflex curvature of the spine, the goal is to increase the volume of the spinal channel and reduce the compression of the nerve tissue. Knee-jerk reaction to pain is an non physiological change of the setting of the spine in the frontal plane.

    In addition to autogenous or allogeneic bone grafts, fusion cages composed of metal or plastic are being used increasingly as spacers for interbody fusion of spinal segments. The goal of this study was the mechanical testing of carbon fiber reinforced plastic (CFRP) fusion cages used for anterior lumbar interbody fusion. With a special testing device according to American Society for Testing and Materials (ASTM) standards, the mechanical properties of the implants were determined under four different loading conditions. The implants (UNION cages, Medtronic Sofamor Danek) provide sufficient axial compression, shear, and torsional strength of the implant body. Ultimate axial compression load of the fins is less than the physiological compression loads at the lumbar spine. Therefore by means of an appropriate surgical technique parallel grooves have to be reamed into the endplates of the vertebral bodies according to the fin geometry. Thereby axial compression forces affect the implants body and the fins are protected from damaging loading. Using a supplementary anterior or posterior instrumentation, in vivo failure of the fins as a result of physiological shear and torsional spinal loads is unlikely. Due to specific complications related to autogenous or allogeneic bone grafts, fusion cages made of metal or carbon fiber reinforced plastic are an important alternative implant in interbody fusion.

    To determine the effect of degenerative disease of the lumbar spine on bone mineral density in the lumbar spine and femoral neck. We reviewed radiographs and dual energy x-ray absorptiometry scans of the lumbar spine and hip in 305 Caucasian women with suspected osteoporosis. One hundred and eight-six patient remained after excluding women less than 40 years of age (n=18) and those with hip osteoarthritis, scoliosis, lumbar spine fractures, lumbar spinal instrumentation, hip arthroplasty, metabolic bone disease other than osteoporosis, or medications known to influence bone metabolism (n=101). On the basis of lumbar spine radiographs, those with absent/mild degenerative disease were assigned to the control group and those with moderate/severe degenerative disease to the degenerative group. Spine radiographs were evaluated for degenerative disease by two radiologists working independently; discrepant evaluations were resolved by consensus. Lumbar spine and femoral neck bone mineral density was compared between the two groups. Forty-five (24%) of 186 women were assigned to the degenerative group and 141 (76%) to the control group. IN the degenerative group, mean bone mineral density measured 1.075g/cm? in the spine and 0.788g/cm{sup 2} in the femoral neck, while for controls the corresponding figures were 0.989g/cm{sup 2} and 0.765g/cm{sup 2}. Adjusted for age, weight and height by means of analysis of variance, degenerative disease of the lumbar spine was a significant predictor of increased bone mineral density in the spine (p=0.0001) and femoral neck (p=0.0287). Our results indicate a positive relationship between degenerative disease of the lumbar spine and bone mineral density in the lumbar spine and femoral neck, and suggest that degenerative disease in that region, which leads to an intrinsic increase in bone mineral density in the femoral neck, may be a good negative predictor of osteoporotic hip fractures.

    The purpose of this paper is to evaluate and analyze the radiological findings of 13 cases of lumbar spondylolisthesis with intact neural arch at Han-Gang Sung- Shim Hospital during period from Jan. 1975 to June 1980. 1. The age distribution of the patients varied from 31 to 83 years old. The average of the age was 53 years old. 12 patients were female and only one patient was male. 2. All cases revealed anterior slipping of the L4 body on the L5 body, of which degree was classified by Meyerding's method, first degree in 12 patients and second degree in one patient. 3. The angle between the pedicle and inferior articular facet of affected vertebra was measured by Junghann's method. The average of angle was 123 degree. 4. Of 13 cases, 2 cases who had neural compression caused by dislocation of the vertebral bodies and intrusion of lamina and arthritic facets into stenotic spinal canal treated by laminar decompression including foraminotomy. Good results were obtained. 5. The secondary degenerative change of the vertebra was considered to be the cause of the spondylolisthesis with intact neural arch.

    Background There has been some controversy related to the use of the Wallis system,rather than disc fusion in the treatment of patients with degenerative spine disease.Furthermore,there are no reports concerning the application of this dynamic stabilization system in Chinese patients,who have a slightly different lifestyle with Western patients.The aim of this study was to assess the safety and efficacy of the dynamic stabilization system in the treatment of degenerative spinal diseases in Chinese patients.Methods The clinical outcomes of 20 patients with lumbar degenerative disease treated by posterior decompression with the Wallis posterior dynamic lumbar stabilization implant were studied.All of the patients completed the visual analogue scale and the Chinese version of the Oswestry Disability Index.The following radiologic parameters were measured in all patients:global lordotic angles and segmental lordotic angles (stabilized segments,above and below adjacent segments).The range of motion was then calculated.Results Nineteen patients (95%) were available for follow-up.The mean follow-up period was (27.25±5.16) months (range 16-35 months).The visual analogue scale decreased from 8.55±1.21 to 2.20±1.70 (P <0.001),and the mean score on the Chinese version of the Oswestry Disability Index was improved from 79.58%±15.93% to 22.17%±17.24% (P <0.001).No significant changes were seen in the range of motion at the stabilized segments (P=0.502) and adjacent segments (above,P=0.453; below,P=0.062).The good to excellent result was 94.4% at the latest follow-up.No complications related to the use of the Wallis posterior dynamic lumbar stabilization occurred.Conclusions It was found to be both easy and safe to use the Wallis posterior dynamic lumbar stabilization implant in the treatment of degenerative lumbar disease,and the early therapeutic effectiveness is good.The Wallis system provides an alternative method for the treatment of lumbar degenerative

    INTRODUCTION: Spinal lengthening in microgravity is thought to cause back pain in astronauts. A spinal compression harness can compress the spine to eliminate lengthening but the loading condition with harness is different than physiologic conditions. Our purpose was to compare the effect of spine compression with a harness in supine position on disk height and spinal curvature in the lumbar spine to that of upright position as measured using a vertically open magnetic resonance imaging system. METHODS: Fifteen healthy subjects volunteered. On day 1, each subject lay supine for an hour and a baseline scan of the lumbar spine was performed. After applying a load of fifty percent of body weight with the harness for thirty minutes, the lumbar spine was scanned again. On day 2, after a baseline scan, a follow up scan was performed after kneeling for thirty minutes within the gap between two vertically oriented magnetic coils. Anterior and posterior disk heights, posterior disk bulging, and spinal curvature were measured from the baseline and follow up scans. RESULTS: Anterior disk heights increased and posterior disk heights decreased compared with baseline scans both after spinal compression with harness and upright posture. The spinal curvature increased by both loading conditions of the spine. DISCUSSION: The spinal compression with specially designed harness has the same effect as the physiologic loading of the spine in the kneeling upright position. The harness shows some promise as a tool to increase the diagnostic capabilities of a conventional MR system.

    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.

    Objective. Signal intensity changes in lumbar pedicles, similar to those described in vertebral body endplates adjacent to degenerated discs, have been described as an ancillary sign of spondylolysis on MRI. The purpose of this study was to determine whether pedicle marrow signal intensity changes also occur in association with facet degenerative joint disease.Design. Eighty-nine lumbar spine MRI examinations without spondylolysis were reviewed for marrow signal intensity changes in pedicles and vertebral bodies as well as for facet degenerative joint disease.Results. Five percent (46/890) of lumbar pedicles in 23 patients had marrow signal intensity changes. Ninety-one percent (42/46) of the abnormal pedicles had adjacent degenerative joint disease of the facets, while only 21% (189/890) of normal pedicles had adjacent facet degenerative joint disease (p<0.001). Eighty-nine percent (41/46) of the pedicles with marrow signal intensity changes had adjacent degenerative disc disease.Conclusions. Pedicle marrow signal intensity changes are not a specific sign of spondylolysis; they are commonly seen with adjacent facet degenerative joint disease in the absence of spondylolysis. Pedicle marrow signal intensity changes are probably a response to abnormal stresses related to abnormal motion or loading caused by the degenerative changes in the spinal segment. (orig.)

    Changes in movement variability and complexity may reflect an adaptation strategy to fatigue. One unresolved question is whether this adaptation is hampered by the presence of low back pain (LBP). This study investigated if changes in movement variability and complexity after fatigue are influenced by the presence of LBP. It is hypothesised that pain free people and people suffering from LBP differ in their response to fatigue. The effect of an isometric endurance test on lumbar movement was tested in 27 pain free participants and 59 participants suffering from LBP. Movement variability and complexity were quantified with %determinism and sample entropy of lumbar angular displacement and velocity. Generalized linear models were fitted for each outcome. Bayesian estimation of the group-fatigue effect with 95% highest posterior density intervals (95%HPDI) was performed. After fatiguing %determinism decreased and sample entropy increased in the pain free group, compared to the LBP group. The corresponding group-fatigue effects were 3.7 (95%HPDI: 2.3-7.1) and -1.4 (95%HPDI: -2.7 to -0.1). These effects manifested in angular velocity, but not in angular displacement. The effects indicate that pain free participants showed more complex and less predictable lumbar movement with a lower degree of structure in its variability following fatigue while participants suffering from LBP did not. This may be physiological responses to avoid overload of fatigued tissue, increase endurance, or a consequence of reduced movement control caused by fatigue. Copyright © 2017 Elsevier Ltd.

    Full Text Available The anaerobic skin commensal Propionibacterium acnes is an underestimated cause of human infections and clinical conditions. Previous studies have suggested a role for the bacterium in lumbar disc herniation and infection. To further investigate this, five biopsy samples were surgically excised from each of 64 patients with lumbar disc herniation. P. acnes and other bacteria were detected by anaerobic culture, followed by biochemical and PCR-based identification. In total, 24/64 (38% patients had evidence of P. acnes in their excised herniated disc tissue. Using recA and mAb typing methods, 52% of the isolates were type II (50% of culture-positive patients, while type IA strains accounted for 28% of isolates (42% patients. Type III (11% isolates; 21% patients and type IB strains (9% isolates; 17% patients were detected less frequently. The MIC values for all isolates were lowest for amoxicillin, ciprofloxacin, erythromycin, rifampicin, tetracycline, and vancomycin (≤1mg/L. The MIC for fusidic acid was 1-2 mg/L. The MIC for trimethoprim and gentamicin was 2 to ≥4 mg/L. The demonstration that type II and III strains, which are not frequently recovered from skin, predominated within our isolate collection (63% suggests that the role of P. acnes in lumbar disc herniation should not be readily dismissed.

    The goal of this article is to report our experience on intradural lumbar disc herniation, consider the causes of this pathology, and analyze it from clinical, diagnostic, and therapeutic perspectives with a particular emphasis on the role of MRI in preoperative diagnosis. We analyzed nine patients treated surgically for intradural lumbar disc hernia. All of them underwent surgery, and hemilaminectomy was performed. In six cases, the diagnosis of intradural herniation was definitive and, in the three remaining, it was confirmed at surgery. In five cases, CT (with no contrast medium) of the lumbar area revealed disc herniation, but none could it confirm its intradural location. Myelography was performed in two cases but also could not prove intradural extrusion. Magnetic resonance imaging study was used in four cases. In five, the postoperative outcome has been excellent. Patients 6 and 9 recovered anal function postoperatively; patient 6 suffered from occasional and mild micturition urgency. The three patients previously operated (1, 2, 7) showed good outcome. Presently, we believe that radiologic diagnosis of intradural herniation is possible in carefully selected patients, thanks to MRI with gadolinium.

    Full Text Available Background: The details of lumbar disk hernia are specifically described in imaging studies, which leads to very specific diagnosis contributing to its appropriate treatment. Objective: To characterize through imaging studies the lumbar disk hernia in operated patients. Methods: Descriptive observational, correlational, retrospective study of a series of cases, carried out in the University Hospital “Dr. Gustavo Aldereguía Lima” of Cienfuegos, from 2000 to 2005, including all the patients who required imaging studies for a suspect of lumbar disk hernia, who received surgical treatment in that institution. The available imaging means were used: spine simple radiography in lumbar area, myelography and computerized axial tomography. Results: Males were more affected by lumbar disk hernia. The most common sings observed through spine simple radiography in lumbar area were: decrease of the intervertebral space and arthrosic changes in the vertebral bodies. Myelography was performed in six patients and three of them were positive. The most common kind of hernia according with their localization was the lateral, and according with the amount of herniated material, the protruded hernia. The most affected spaces were: L5- S1 and L4-L5. The patients of the third and fourth decade of life were the most affected, with a prevalence of the protruded hernia in the L5-S1 y L4 -L5 spaces. Conclusions: The imaging studies contributed to a correct characterization of lumbar disk hernia.

    Full Text Available ABSTRACT Objectives: To demonstrate the recovery of lumbar sagittal pelvic alignment and sagittal pelvic balance after surgical reduction of lumbar spondylolisthesis and establish the benefits of the surgery for reduction and fixation of the lumbar spondylolisthesis with 360o circumferential arthrodesis for 2 surgical approaches by clinical and functional evaluation. Method: Eight patients with lumbar spondylolisthesis treated with surgical reduction and fixation of listhesis and segmental circumferential fusion with two surgical approaches were reviewed. They were evaluated before and after treatment with Oswestry, Visual Analogue for pain and Odom scales, performing radiographic measurement of lumbar sagittal alignment and pelvic sagittal balance with the technique of pelvic radius. Results: Oswestry scales and EVA reported improvement of symptoms after treatment in 8 cases; the Odom scale had six outstanding cases reported. The lumbar sagittal alignment presented a lumbosacral lordosis angle and a lumbopelvic lordosis angle reduced in 4 cases and increased in 4 other cases; pelvic sagittal balance increased the pelvic angle in 4 cases and decreased in 3 cases and the sacral translation of the hip axis to the promontory increased in 6 cases. Conclusion: The surgical procedure evaluated proved to be useful by modifying the lumbar sagittal alignment and the pelvic balance, besides reducing the symptoms, enabling the patient to have mobility and movement and the consequent satisfaction with the surgery.

    Sciatica is defined as pain or discomfort along the regions innervated by the sciatic nerve. Compression or irritation of lumbar spinal roots, most commonly because of lumbar disc herniation or spinal stenosis, causes sciatica in the vast majority of cases. Although it is rather uncommon, many pathologies have reported to cause nondiscogenic sciatica. A 70-year-old woman presented with intractable sciatic pain which was not elicited by posture change or cough. Sitting on the affected side provoked more pain than standing or walking. Magnetic resonance imaging revealed both spondylolisthesis with lumbar stenosis and compression of the gluteal portion of the sciatic nerve by varicotic gluteal veins. Given the atypical presentation of spinal root compression, gluteal vascular compressive neuropathy was suspected. Ligation and resection of varicotic vein resulted in relief of the patient's pain. To our knowledge, cases with varicosity-caused sciatica were limited in the literature review.

    Lumbar stenosis has been well discussed recently, especially at the 64th French Orthopaedic Society (SOFCOT: July 1989). The results of different surgical treatments were considered as good, but the indications for surgical treatment were not clear cut. Laminectomy is not the only treatment of spinal stenosis. Laminectomy is an approach with its own rate of complications (dural tear, fibrosis, instability... ).Eight years ago, J. Sénégas described what he called the "recalibrage" (enlargement). His feeling was that, in the spinal canal, we can find two different AP diameters. The first one is a fixed constitutional AP diameter (FCAPD) at the cephalic part of the lamina. The second one is a mobile constitutional AP diameter (MCAPD) marked by the disc and the ligamentum flavum. This diameter is maximal in flexion, minimal in extension. The nerve root proceeds through the lateral part of the canal: first above, between the disc and the superior articular process, then below, in the lateral recess bordered by the pedicle, the vertebral body and the posterior articulation. With the degenerative change the disc space becomes shorter, the superior articular process is worn out with osteophytes. These degenerative events are complicated by inter vertebral instability increasing the stenosis. The idea of the "recalibrage" is to remove only the upper part of the lamina with the ligamentum flavum and to cut the hypertrophied anterior part of the articular process from inside. If needed the disc and other osteophytes are removed. The surgery is finished with a ligamentoplasty reducing the flexion and preventing the extension by a posterior wedge.Our experience in spine surgery especially in scoliosis surgery, showed us that it was possible to cure a radicular compression without opening the canal. The compression is then lifted by the 3D reduction and restoration of an anatomy as normal as possible. Lumbar stenosis is the consequence of a degenerative process. Indeed, hip

    axis, 0.36 vs 0.32, p < 0.01). These differences were most evident at L-4. This study demonstrated lumbar pedicle asymmetry in degenerative lumbar scoliosis. The authors speculate that these asymmetrical changes were attributed to the remodeling caused by axial load imbalance and the limited space available for pedicles on the concave side. On the concave side, because of the narrower pedicle diameter and larger axial angle, surgeons should carefully determine screw size and direction when inserting pedicle screws to prevent possible pedicle wall breakage and neural damage.

    Full Text Available Abstract Background X-ray images of lumbar degenerative diseases often show not only claw osteophytes, but also pairs of osteophytes that form in a direction away from the adjacent disc. We have investigated the direction of the formation of anterior lumbar vertebral osteophytes across the lumbar vertebrae using a sufficient number of lumbar radiographs, because osteophytes images can provide essential information that will contribute to the understanding of the pathology and progress of lumbar spine degeneration. Methods The direction of the formation of 14,250 pairs of anterior lumbar vertebral osteophytes across the adjacent intervertebral discs in 2,850 patients who were all over 60 years old was investigated. Anterior lumbar vertebral osteophytes were distributed into six groups based on the direction of extension of each pair of osteophytes across the intervertebral disc space. Results In L1–L2 and L2–L3, the number of patients classified into groups B (the pair of osteophytes extended in the direction of the adjacent disc and C (almost complete bone bridge formation by a pair of osteophytes across the intervertebral disc space was larger than that classified into group D (the pair of osteophytes extended in a direction away from the adjacent disc. In L3–L4, L4–L5 and L5-S1, the number of patients in group D was greater than that of patients belonging to groups B and C. Conclusion Our study showed that pairs of osteophytes frequently formed in the direction of the adjacent disc in the upper lumbar vertebrae (L1–L2 and L2–L3 and in the direction away from the adjacent disc in middle or lower lumbar vertebrae (L3–L4, L4–L5, and L5-S1.

    Lumbar interbody fusion is a widely accepted surgical procedure for patients with lumbar degenerative spondylolisthesis and lumbar spinal instability in the active age group. However, in elderly patients, it is often questionable whether it is truly necessary to construct rigid fixation for a short period of time. In recent years, we have been occasionally performing posterior dynamic stabilization in elderly patients with such lumbar disorders. Posterior dynamic stabilization was performed in 12 patients (6 women, 70.9 ± 5.6 years old at the time of operation) with lumbar degenerative spondylolisthesis in whom % slip was less than 20% or instability associated with lumbar disc herniation between March 2011 and March 2013. Movement occurs through the connector linked to the pedicle screw. In practice, 9 pairs of D connector system where the rod moves in the perpendicular direction alone and 8 pairs of Dynamic connector system where the connector linked to the pedicle screw rotates in the sagittal direction were installed. The observation period was 77-479 days, and the mean recovery rate of lumbar Japanese Orthopedic Association (JOA) score was 65.6 ± 20.8%. There was progression of slippage due to slight loosening in a case with lumbar degenerative spondylolisthesis, but this did not lead to exacerbation of the symptoms. Although follow-up was short, there were no symptomatic adjacent vertebral and disc disorders during this period. Posterior dynamic stabilization may diminish the development of adjacent vertebral or disc disorders due to lumbar interbody fusion, especially in elderly patients, and it may be a useful procedure that facilitates decompression and ensures a certain degree of spinal stabilization.

    Full Text Available CONTEXTO: O fibrohistiocitoma benigno intra-ósseo é uma neoplasia rara, caracterizada por proliferação fibroblástica e fibras colágenas. A dor na região lombar é uma queixa freqüente em muitos pacientes, mas, na maioria das vezes está relacionada com causa muscular ou degenerativa. RELATO DE CASO: Relata-se aqui o caso de um paciente com diagnóstico de fibrohistiocitoma benigno ósseo na coluna lombar que apresentava queixa de lombalgia há cinco meses antes do diagnóstico. Foi submetida à biópsia aberta transpedicular na quarta vértebra lombar ,e, posteriormente realizada curetagem da lesão via anterior retroperitonial e artrodese vertebral de L3-L5 com enxerto de fíbula. CONCLUSÃO: Apesar de raro, o fibrohistiocitoma benigno intra-ósseo deve ser uma das hipóteses quando observamos uma lesão primária na coluna vertebral.CONTEXT: Benign intraosseous fibrous histiocytoma is a rare neoplasia, characterized by fibroblastic and collagenous fiber proliferation. Pain in the lumbar region is a frequent complaint in many patients, but most of times it is associated to muscular or degenerative causes. CASE REPORT: Here we report a case of a patient diagnosed with benign bone fibrous histiocytoma in the lumbar spine who complained of lumbar pain dating five months prior to diagnosis. The patient was submitted to open transpedicular biopsy in the forth lumbar vertebra, and subsequently, lesion curettage was performed via anterior retroperitoneal and L3-L5 vertebral arthrodesis using a fibular graft. CONCLUSION: Although rare, benign intraosseous fibrohistiocytoma should be taken into consideration when a primary lesion is observed in the spine.

    Radiological study. To asses standard values, intra- and interobserver reliability and reproducibility of sacral slope (SS) and lumbar lordosis (LL) and the correlation of these parameters in patients with lumbar spinal stenosis (LSS). Anteroposterior and lateral X-rays of the lumbar spine of 102 patients with LSS were included in this retrospective, radiologic study. Measurements of SS and LL were carried out by five examiners. Intraobserver correlation and correlation between LL and SS were calculated with Pearson's r linear correlation coefficient and intraclass correlation coefficients (ICC) were calculated for inter- and intraobserver reliability. In addition, patients were examined in subgroups with respect to previous surgery and the current therapy. Lumbar lordosis averaged 45.6° (range 2.5°-74.9°; SD 14.2°), intraobserver correlation was between Pearson r = 0.93 and 0.98. The measurement of SS averaged 35.3° (range 13.8°-66.9°; SD 9.6°), intraobserver correlation was between Pearson r = 0.89 and 0.96. Intraobserver reliability ranged from 0.966 to 0.992 ICC in LL measurements and 0.944-0.983 ICC in SS measurements. There was an interobserver reliability ICC of 0.944 in LL and 0.990 in SS. Correlation between LL and SS averaged r = 0.79. No statistically significant differences were observed between the analyzed subgroups. Manual measurement of LL and SS in patients with LSS on lateral radiographs is easily performed with excellent intra- and interobserver reliability. Correlation between LL and SS is very high. Differences between patients with and without previous decompression were not statistically significant.

    Full Text Available There have been few studies comparing the clinical and radiographic outcomes between the Dynesys dynamic stabilization system and posterior lumbar interbody fusion (PLIF. The objective of this study is to compare the clinical and radiographic outcomes of Dynesys and PLIF for lumbar degenerative disease.Of 96 patients with lumbar degenerative disease included in this retrospectively analysis, 46 were treated with the Dynesys system and 50 underwent PLIF from July 2008 to March 2011. Clinical and radiographic outcomes were evaluated. We also evaluated the occurrence of radiographic and symptomatic adjacent segment degeneration (ASD.The mean follow-up time in the Dynesys group was 53.6 ± 5.3 months, while that in the PLIF group was 55.2 ± 6.8 months. At the final follow-up, the Oswestry disability index and visual analogue scale score were significantly improved in both groups. The range of motion (ROM of stabilized segments in Dynesys group decreased from 7.1 ± 2.2° to 4.9 ± 2.2° (P < 0.05, while that of in PLIF group decreased from 7.3 ± 2.3° to 0° (P < 0.05. The ROM of the upper segments increased significantly in both groups at the final follow-up, the ROM was higher in the PLIF group. There were significantly more radiographic ASDs in the PLIF group than in the Dynesys group. The incidence of complications was comparable between groups.Both Dynesys and PLIF can improve the clinical outcomes for lumbar degenerative disease. Compared to PLIF, Dynesys stabilization partially preserves the ROM of the stabilized segments, limits hypermobility in the upper adjacent segment, and may prevent the occurrence of ASD.

    During percutaneous lumbar spine needle interventions, alignment of the preoperative computed tomography (CT) with intraoperative ultrasound (US) can augment anatomical visualization for the clinician. We propose an approach to rigidly align CT and US data of the lumbar spine. The approach involves an intensity-based volume registration step, followed by a surface segmentation and a point-based registration of the entire lumbar spine volume. A clinical feasibility study resulted in mean registration error of approximately 3 mm between CT and US data.

    Low back pain resulting from lumbar disc herniation is a common reason for referral for physical therapy. There is no evidence to support the management of lumbar disc herniation and derangement using mechanical traction combined with lumbar extension exercises. Therefore, the purpose of this case report was to describe and discuss the use of mechanical traction in conjunction with lumbar extension exercises for a patient with a lumbar herniated disc. The patient was a 49-year-old male referred to physical therapy with a medical diagnosis of a lumbar herniated disc at L5-S1 with compression of the L5 nerve root confirmed by MRI. The patient's chief complaint was pain over the left lumbosacral and central lumbar region with radiating pain into the left buttock accompanied by numbness and tingling in the left lower leg and foot. The patient was seen for a total of 14 visits. The first 5 days (2 weeks) of therapy consisted of lumbar extension exercises. For the following nine visits (over a 3-week period), mechanical traction was added as an adjunct to the extension exercises. Outcome measures included the Oswestry Disability Questionnaire, Back Pain Function Scale (BPFS), and the Numeric Pain Rating Scale (NPRS). Results from initial evaluation to discharge (Oswestry: 36% to 0%; BPFS: 33/60 to 57/60; NPRS: 7/10 to 0/10) demonstrated that the patient no longer experienced low back pain and improved in terms of functional status and pain-related disability. The patient no longer complained of numbness and tingling in the left lower extremity and the goals for the patient had been attained. The data from this case report suggests lumbar extension exercises in conjunction with mechanical traction facilitated the patient's improvement in pain and return to prior level of function.

    Intervertebral disc degeneration and facet joint osteoarthritis of the lumbar spine are, among others, wellknown as a cause of low back and lower extremity pain. Together with their secondary disorders they set a big burden on health care systems and economics worldwide. Despite modern imaging modalities, such as magnetic resonance imaging, for a large proportion of patients with low back pain(LBP) it remains difficult to provide a specific diagnosis. The fact that nearly all the lumbar structures are possible sources of LBP, may serve as a possible explanation. Furthermore, our clinical experience confirms, that imaging alone is not a sufficient approach explaining LBP. Here, the Oswestry Disability Index, as the most commonly used measure to quantify disability for LBP, may serve as an easy-toapply questionnaire to evaluate the patient’s ability to cope with everyday life. For therapeutic purposes, among the different options, the lumbar facet joint intraarticular injection of corticosteroids in combination with an anaesthetic solution is one of the most frequently performed interventional procedures. Although widely used the clinical benefit of intra-articular steroid injections remains controversial. Therefore, prior to therapy, standardized diagnostic algorithms for an accurate assessment, classification and correlation of degenerative changes of the lumbar spine are needed.

    The study was to comprehensively compare the postoperative outcome and imaging parameter characters in a short/middle period between the percutaneous endoscopic lumbar discectomy (PELD) and the internal fixation of bone graft fusion (the most common form is posterior lumbar interbody fusion [PLIF]) for the treatment of adjacent segment lumbar disc prolapse with stable retrolisthesis after a previous lumbar internal fixation surgery.In this retrospective case-control study, we collected the medical records from 11 patients who received PELD operation (defined as PELD group) for and from 13 patients who received the internal fixation of bone graft fusion of lumbar posterior vertebral lamina decompression (defined as control group) for the treatment of the lumbar disc prolapse combined with stable retrolisthesis at Department of Spine Surgery, the Third Hospital of Hebei Medical University (Shijiazhuang, China) from May 2010 to December 2015. The operation time, the bleeding volume of perioperation, and the rehabilitation days of postoperation were compared between 2 groups. Before and after surgery at different time points, ODI, VAS index, and imaging parameters (including Taillard index, inter-vertebral height, sagittal dislocation, and forward bending angle of lumbar vertebrae) were compared.The average operation time, the blooding volume, and the rehabilitation days of postoperation were significantly less in PELD than in control group. The ODI and VAS index in PELD group showed a significantly immediate improving on the same day after the surgery. However, Taillard index, intervertebral height, sagittal dislocation in control group showed an immediate improving after surgery, but no changes in PELD group till 12-month after surgery. The forward bending angle of lumbar vertebrae was significantly increased and decreased in PELD and in control group, respectively.PELD operation was superior in terms of operation time, bleeding volume, recovery period, and financial

    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.

    The use of anticoagulants and antiplatelet agents has largely increased. Diagnostic lumbar puncture in patients taking these drugs represents a challenge considering the opposing risks of bleeding and thrombotic complications. To date there are no controlled trials, specific guidelines, nor clear recommendations in this area. In the present review we make some recommendations about lumbar puncture in patients using these drugs. Our recommendations take into consideration the pharmacology of these drugs, the thrombotic risk according to the underlying disease, and the urgency in cerebrospinal fluid analysis. Evaluating such information and a rigorous monitoring of neurological symptoms after lumbar puncture are crucial to minimize the risk of hemorrhage associated neurological deficits. An individualized patient decision-making and an effective communication between the assistant physician and the responsible for conducting the lumbar puncture are essential to minimize potential risks.

    Lumbar hernia, a defect of the posterior abdominal wall, is a very rare condition. The repair of a posterior abdominal wall hernia by simply closing the hernia port with sutures may not be adequate, especially when the herniation is due to a weakness in the abdominal wall. Recently, a simple, logical method of tension-free repair has become a popular means for the treatment of various abdominal wall hernias. Previous studies have advocated the use of tension-free repair for lumbar hernia; the technique uses a mesh replacement and requires an extensive incision. Herein we present a case of superior lumbar hernia. Our technique consisted of a laparoscopic tension-free hernioplasty with the application of a Prolene mesh. This technique, which provides an excellent operative view, is safe, feasible, and minimally invasive. We conclude that laparoscopic tension-free repair should be the preferred option for the treatment of lumbar hernia.

    Full Text Available Abstract Introduction Lumbar hernia is a rare abdominal wall defect and clinical suspicion is necessary for diagnosis. Case presentation We report the case of a 40-year-old Caucasian woman with a superior lumbar hernia (Grynfeltt hernia initially misdiagnosed as a recurrent lipoma. The correct diagnosis was made intra-operatively and the hernia was repaired using synthetic mesh. The patient was free of recurrence at 4 months after the operation. Conclusion A lumbar or flank mass should always raise suspicion of a lumbar hernia. Ultrasound and computed tomography may confirm the diagnosis. Adequate surgical treatment should be planned on the basis of etiology and hernia size. Both open and laparoscopic techniques can be used with good results.

    The increasing application of magnetic resonance (MR) imaging of the spine has raised the awareness of lumbar facet synovial cysts (LFSC). This well recognised, yet uncommon condition, presents with low back pain and radiculopathy due to the presence of an extradural mass. The commonest affected level is L4/5 with a mild degenerative spondylolisthesis a frequent associated finding. MR imaging is the technique of choice to detect and diagnose a LFSC. This pictorial essay, drawing on experience of 43 cases seen in 40 patients, illustrates the spectrum of appearances that can be encountered and suggest differing causes for the variable signal characteristics exhibited. Computed tomography (CT) can be of value in some cases to aid interpretation of the MR images. In addition, CT facet arthrography by injection of air or iodinated non-ionic contrast medium may be used to confirm the diagnosis in doubtful cases as well as noting whether the patients presenting symptoms can be provoked. A comprehensive review of the existing literature is presented. (orig.)

    Full Text Available Introduction:   Sometimes physicians need to assess some markers on selected children's cerebrospinal fluid specimen according to lumbar puncture (LP. Although immediate diagnosis and treatment especially for meningitis is necessary, But just at this moment, due to some incorrect believe in society, some parents may not allow physician to do LP. The reality is that most of these people, if they have enough information about this issue, will not interfere. This study aimed to assess parent 's knowledge and attitudes toward this subject.   Materials and Method: Through a cross - sectional study we evaluated 91 parents, who their child must been undergone LP as physician’s decision, selected during 18 months using purposive sampling. The data collection tool was a questionnaire including two sections of the child and the parents' knowledge and attitudes.  Scientific validity of the questionnaire was confirmed by content validity. To achieve the objectives, SPSS ver.15 and descriptive statistics and chi-square test were used.   Results: 61 parents(67%  mentioned   fear of some side effects as the main reason of their children 's  LP discontent .The most important  cause of  fear was low back pain according to  50 (54.9% parents 's view. 70 parents (76.9% had some satisfaction after performing  LP .There was  statistically significant difference between proportion of satisfied parents and non-satisfied ones (p

    Full Text Available Lumbar spondylarthrosis is a degenerative disease that affects the joint structures of the lumbar spine. In the course of time, numerous studies on the role of hydro-kinesiotherapy in the treatment of lumbar spondylosis have been conducted. The aim of this research is motivated by the significantly high number of patients with chronic pain in the lumbar spine due to lumbar spondylosis, as well as by the negative impact on their quality of life through the impairment of the activities of daily living. The prospective longitudinal study was carried out at the Clinical Rehabilitation Hospital Cluj-Napoca. The study included 35 patients with chronic low back pain and mobility limitation in the lumbar spine. The patients were assigned to two groups: the study group formed by 20 patients and the control group consisting of 15 patients aged between 40-70 years. The treatment of the patients included in the study was performed over a two week period and consisted of a hydro-kinesiotherapy program, for the patients of the study group, the duration of a treatment session being 40 minutes. Both the subjects of the study group and of the control group also benefited from sedative massage of the lumbosacral spine, kinesiotherapy, laser therapy of the lumbar spine. The patients were evaluated using Schober’s test, the Visual Analogue Scale, the Oswestry index. These evaluation methods were applied to the patients of both groups at the beginning of the rehabilitation programs and after two weeks. The results of the study demonstrated the therapeutic efficacy of the medical rehabilitation programs that included hydro-kinesiotherapy programs. The patients of both groups had improvements through a decrease of lumbar pain, an increase in lumbar spine mobility, as well as in the patients’ ability to organize themselves in the activities of daily living. However, the patients of the study group, with a hydro-kinesiotherapy program performed for two weeks, had

    A magnetic resonance imaging follow-up study of lumbar arteries among patients with sciatica with chronic Chlamydia pneumoniae infection. To determine whether chronic infection causes occlusion of lumbar arteries. C. pneumoniae infection is associated with coronary heart disease, and the infectious pathogen has also been detected in abdominal aortic aneurysms and in atherosclerotic plaques. No studies are available on the effect of this infectious agent on lumbar arteries. Chronic infection was defined as persistent high positive immunoglobulin G and/or immunoglobulin A antibodies and/or the presence of immune complexes. The lumbar arteries, evaluated with two-dimensional time-of-flight magnetic resonance angiography, were scored as normal, narrowed, or occluded. The differences in the segmental and whole lumbar spine (segments L1-L4) sum of arterial occlusion at baseline and at 3 years, and the incidence of new arterial stenosis were compared in patients with and without chronic infection using the Kolmogorov-Smirnov test. Patients with chronic infection were more likely to be persistent smokers (P = 0.006), male (P = 0.04), and more obese (P = 0.02) compared to patients with normal antibody levels. They had significantly higher degree of arterial stenosis at L4 segment at baseline and at 3 years (P = 0.001 and 0.002, respectively), in the whole lumbar spine at baseline and at 3 years (P < 0.001 for both), and at L1 and L3 segments at 3 years (P = 0.013 for both). The incidence of new arterial stenosis was similar in both patient groups. Patients with chronic infection also had significantly higher grade of endplate degeneration at L4-L5 (P = 0.008). The results of this study suggest that chronic C. pneumoniae infection may induce stenosis of lumbar arteries.

    Different studies have shown that atrophy of paraspinal muscles arises after open dorsal lumbar fusion, and the reasons for this atrophy are still not yet fully clarified. This prospective study investigates the extent of atrophy of the lumbar paraspinal muscles after open lumbar interbody fusion, its possible causes, and their association with clinical outcome measures. Thirty consecutive patients were prospectively included (13 male, 17 female, median age 60.5 years, range 33-80 years). Mono or bisegmental, posterior lumbar interbody fusion and instrumentation was performed applying a conventional, open lumbar midline approach. Clinical outcome was assessed by the Short Form (36) Health Survey (SF-36) questionnaire and visual analogue scale. Needle electromyography of paraspinal muscles was performed preoperatively, at 6 and 12 months. Serum values of creatine kinase, lactate dehydrogenase and myoglobin were determined preoperatively, at day 2 after surgery and at discharge. Paraspinal muscle volume was determined by volumetric analysis of thin-slice computed tomography scans preoperatively and 1 year after surgery. There was a significant increase of electromyographic denervation activity (p =0.024) and reduced recruitment of motor units (p = 0.001) after 1 year. Laboratory studies showed a significant increase of CK (p muscle volume decreased from 67.8 to 60.4 % (p muscle volume (K = -0.219, p = 0.002). Paraspinal muscle volume is significantly correlated with physical outcome (K = 0.169, p = 0.020), mental outcome (K = 0.214, p = 0.003), and pain (K = 0.382, p Atrophy of paraspinal muscles after open, posterior lumbar interbody fusion seems to be associated with denervation, as well as direct muscle trauma during surgery. While muscle atrophy is also correlated with a worse clinical outcome, it seems to be a determining factor for successful lumbar spine surgery.

    2016-04-11

    Musculoskeletal simulations of lumbar spine loading rely on a geometrical representation of the anatomy. However, this data has an inherent inaccuracy. This study evaluates the influence of defined geometrical parameters on lumbar spine loading utilising five parametrised musculoskeletal lumbar spine models for four different postures. The influence of the dimensions of vertebral body, disc, posterior parts of the vertebrae as well as the curvature of the lumbar spine was studied. Additionally, simulations with combinations of selected parameters were conducted. Changes in L4/L5 resultant joint force were used as outcome variable. Variations of the vertebral body height, disc height, transverse process width and the curvature of the lumbar spine were the most influential. These parameters can be easily acquired from X-rays and should be used to morph a musculoskeletal lumbar spine model for subject-specific approaches with respect to bone geometry. Furthermore, the model was very sensitive to uncommon configurations and therefore, it is advised that stiffness properties of discs and ligaments should be individualised.

    Lumbar herniated disks result in lumbar pain with neurologic involvement. Medical treatment and rehabilitation provide improvement for this type of lumbar pain at the early stages. When conservative treatment fails, the surgical option offers the possibility of improving patients' health status. Moojen considers that the application of interspinous spacers provides good results. The purpose of this research is to assess the clinical and imaging results in patients with contained lumbar herniated disk treated with the DYNAMIC INTERSPACER interspinous spacer, a Mexican product. The efficacy of the interspinous device was assessed by means of a near-investigational and longitudinal study conducted at "General Ignacio Zaragoza" ISSSTE Regional Hospital in patients with a diagnosis of lumbar pain. The mean age of the sample is 46.1 years, with an age range of 26-55 years. The treated levels were 6 L5-S1 and 5 L4-L5; two levels were treated in two patients. The mean preoperative VAS score was 8.1. The mean VAS score at postoperative year three was 1.6. Multiple types and brands of foreign interspinous devices are applied in Mexico which results in patients' clinical improvement. We proved that the use of the Mexican interspinous device can clinically improve patients with lumbar pain due to herniated disk. A decrease in the compression of the sac or the nerve roots by the hernia was observed in the comparative preoperative and postoperative MRI images.

    Trigeminal neuralgia (TN) is often secondary to an underlying structural cause, frequently compression of the fifth nerve root by an ectatic artery. Here we describe a case of a 36-year-old woman with symptoms of TN who was found to have severe communicating hydrocephalus. Further investigation revealed a lumbar myxopapillary ependymoma, which in turn was responsible for the communicating hydrocephalus. An argument connecting these seemingly disparate findings is made. This unusual set of circumstances is an example of "action at a distance" in the nervous system, and reminds clinicians to think broadly about the various pathophysiologic mechanisms that can potentially underlie common disorders.

    1984-07-01

    The most common reason a patient is referred for spinal CT examination is to exclude a ruptured intervertebral disc. Besides nerve root entrapment due to herniated disc, a number of unusual or 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 of overlooking 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.

    Pleural effusion is a possible complication of the thoraco-abdominal approach to the spine. It is more commonly a reactive effusion, but it also may be caused by hemothorax, empyema or, less commonly, a chylothorax. The case of a chylothorax is reported as a late onset complication of a double anterior and posterior instrumented fusion of the lumbar spine. Its management and clinical outcome, and a review of the literature is presented. Copyright © 2014 SECOT. Published by Elsevier Espana. All rights reserved.

    Pelvic masses, especially hydatid disease, rarely present with sciatica. We present the computed tomography (CT) and the magnetic resonance imaging (MRI) findings of a 49-year-old female patient with presacral hydatid disease, who was evaluated for her sciatica. We also want to emphasize the importance of assessing the pelvis of patients with symptoms and clinical findings that are inconsistent and that cannot be satisfactorily explained by the spinal imaging findings. isc herniation in the lumbar spine is a well-known etiology of back pains and sciatica, but whenever disc herniation of the lumbar spine is excluded by the employed imaging modalities, then the pelvis should be examined for other possible etiologies of nerve compression. We describe here a patient, who was complaining of sciatica, with no abnormal findings in her lumbar spinal magnetic resonance imaging (MRI). The cause of her sciatica was found to be associated with a pelvic hydatid cyst compressing the lumbosacral nerve plexus. In conclusion, if no pathology is evident for the lumbar discal structures, in connection with the cause of sciatica and lumbar back pains, then the pelvis should also be examined for the possible etiologies of compression of the lumbosacral nerve plexus. Whenever a multiseptated cyst is come across in a patient of an endemic origin with a positive history for hydatid disease like surgery, indicating recurrence, hydatid cyst is the most likely diagnosis.

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 t...

    Full Text Available Abstract Background The human spine is often exposed to mechanical load in vocational activities especially in combination with lifting, carrying and positioning of heavy objects. This also applies in particular to nursing activities with manual patient handling. In the present study a detailed investigation on the load of the lumbar spine during manual patient handling was performed. Methods For a total of 13 presumably endangering activities with transferring a patient, the body movements performed by healthcare workers were recorded and the exerted action forces were determined with regard to magnitude, direction and lateral distribution in the time course with a "measuring bed", a "measuring chair" and a "measuring floor". By the application of biomechanical model calculations the load on the lowest intervertebral disc of the lumbar spine (L5-S1 was determined considering the posture and action force data for every manual patient handling. Results The results of the investigations reveal the occurrence of high lumbar load during manual patient handling activities, especially in those cases, where awkward postures of the healthcare worker are combined with high action forces caused by the patient's mass. These findings were compared to suitable issues of corresponding investigations provided in the literature. Furthermore measurement-based characteristic values of lumbar load were derived for the use in statement procedures concerning the disease no. 2108 of the German list of occupational diseases. Conclusions To protect healthcare workers from mechanical overload and the risk of developing a disc-related disease, prevention measures should be compiled. Such measures could include the application of "back-fairer" nursing techniques and the use of "technical" and" small aids" to reduce the lumbar load during manual patient handling. Further studies, concerning these aspects, are necessary.

    Low back pain (LBP) is a common cause of lost playing time and can be a challenging clinical condition in competitive athletes. LBP in athletes may be associated with joint and ligamentous hypermobility and impairments in activation and coordination of the trunk musculature, however there is limited research in this area. To determine if there is an association between altered lumbar motor control, joint mobility and low back pain (LBP) in a sample of athletes. Fifteen athletes with LBP were matched by age, gender and body mass index (BMI) with controls without LBP. Athletes completed a questionnaire with questions pertaining to demographics, activity level, medical history, need to self-manipulate their spine, pain intensity and location. Flexibility and lumbar motor control were assessed using: active and passive straight leg raise, lumbar range of motion (ROM), hip internal rotation ROM (HIR), Beighton ligamentous laxity scale, prone instability test (PIT), observation of lumbar aberrant movements, double leg lowering and Trendelenburg tests. Descriptive statistics were compiled and the chi square test was used to analyze results. Descriptive statistics showed that 40% of athletes with LBP exhibited aberrant movements (AM), compared to 6% without LBP. 66% of athletes with LBP reported frequently self-manipulating their spine compared to 40% without LBP. No significant differences in motor control tests were found between groups. Athletes with LBP tended to have less lumbar flexion (63 ± 11°) compared to those without LBP (66 ± 13°). Chi-Square tests revealed that the AM were more likely to be present in athletes with LBP than those without (X2 = 4.66, P = 0.03). The presence of aberrant movement patterns is a significant clinical finding and associated with LBP in athletes.

    Although the lumbar spine region is the most common site of injury in golfers, little research has been done on intervertebral loads in relation to the anatomical-morphological differences in the region. This study aimed to examine the biomechanical effects of anatomical-morphological differences in the lumbar lordosis on the lumbar spinal joints during a golf swing. The golf swing motions of ten professional golfers were analyzed. Using a subject-specific 3D musculoskeletal system model, inverse dynamic analyses were performed to compare the intervertebral load, the load on the lumbar spine, and the load in each swing phase. In the intervertebral load, the value was the highest at the L5-S1 and gradually decreased toward the T12. In each lumbar spine model, the load value was the greatest on the kypholordosis (KPL) followed by normal lordosis (NRL), hypolordosis (HPL), and excessive lordosis (EXL) before the impact phase. However, results after the follow-through (FT) phase were shown in reverse order. Finally, the load in each swing phase was greatest during the FT phase in all the lumbar spine models. The findings can be utilized in the training and rehabilitation of golfers to help reduce the risk of injury by considering individual anatomical-morphological characteristics.

    The aim of this study was to observe the clinical effects of bilateral decompression via vertebral lamina fenestration for lumbar interbody fusion in the treatment of lower lumbar instability. The 48 patients comprised 27 males and 21 females, aged 47-72 years. Three cases had first and second degree lumbar spondylolisthesis and all received bilateral vertebral lamina fenestration for posterior lumbar interbody fusion (PLIF) using a threaded fusion cage (TFC), which maintains the three-column spinal stability. Attention was given to ensure the correct pre-operative fenestration, complete decompression and the prevention of adhesions. After an average follow-up of 26.4 months, the one year post-operative X-ray radiographs suggested that the successful fusion rate was 88.1%, and this was 100% in the two-year post-operative radiographs. Moreover, the functional recovery rate was 97.9%. Bilateral vertebral lamina fenestration for lumbar interbody fusion is an ideal surgical method for the treatment of lower lumbar instability. The surgical method retains the spinal posterior column and middle column and results in full decompression and reliable fusion by a limited yet effective surgical approach.

    Infections are an important acquired cause of cerebral arteriopathy. Tuberculous (TB) meningitis leading to infectious cerebral vasculopathy is a rare cause of acute hemiparesis. A 14-year-old male patient was examined after acute hemiparesis developing within 1 day. Neurological examination revealed total hemiplegia on the left side. Brain MRI findings showed bilateral focal T2-weighted signal hyperintensity in the subcortical and deep white matter regions. There were also areas of restricted diffusion in the right basal ganglia. Although the father had a history of pulmonary TB, the patient had not been given TB prophylaxis because of PPD negativity. At lumbar puncture, opening cerebrospinal fluid (CSF) pressure was 50 cm/H20, CSF protein 66.9 mg/dL, and glucose 54 mg/dL (concurrent blood glucose 93 mg/dL); 170 polymorphonuclear leukocytes per cubic millimeter were present in CSF. Following tests for TB, treatment was started immediately with four anti-TB drugs. TB PCR of CSF and acid-fast bacteria (AFB) staining in gastric aspirate were positive. At clinical follow-up, the patient was able to walk with support at the end of the first month. Various infectious agents have been reported as causes of cerebral vasculopathy. TB, which affects a significant number of patients worldwide, should be kept in mind in terms of cerebral vascular complications. Lumbar puncture is essential in order to diagnose TB meningitis.

    Full Text Available BACKGROUND: To evaluate by MRI intervertebral disc degeneration in patients with lumbar degenerative disease using the Pfirrmann grading system and to determine whether Modic changes correlated with the Pfirrmann grades and modified Pfirrmann grades of disc degeneration. METHODS: The clinical data of 108 surgical patients with lumbar degenerative disease were reviewed and their preoperative MR images were analyzed. Disc degeneration was evaluated using the Pfirrmann grading system. Patients were followed up and low back pain was evaluated using the visual analog scale (VAS and the effect of back pain on the daily quality of life was assessed using Oswestry disability index (ODI. RESULTS: Forty-four cases had normal anatomical appearance (Modic type 0 and their Pfirrmann grades were 3.77±0.480 and their modified Pfirrmann grades were of 5.81±1.006. Twenty-seven cases had Modic type I changes and their Pfirrmann grades were 4.79±0.557 and their modified Pfirrmann grades were 7.00±0.832. Thirty-six cases exhibited Modic type II changes and their Pfirrmann grades and modified Pfirrmann grades were 4.11±0.398 and 6.64±0.867, respectively. One case had Modic type III changes. Kruskal-Wallis test revealed significant difference in modified Pfirrmann grade among Modic type 0, I and II changes (P0.05. Binary regression analysis showed that Modic changes correlated most strongly with disc degeneration. Follow up studies indicated that the VAS and ODI scores were markedly improved postoperatively. However, no difference was noted in VAS and ODI scores among patients with different Modic types. CONCLUSION: Modic changes correlate with the Pfirrmann and modified Pfirrmann grades of disc degeneration in lumbar degenerative disease. There is no significant correlation between Modic types and surgical outcomes.

    Lumbar spinal canal stenosis (LSCS) is one of the most common spinal disorders in elderly people, with the number of LSCS patients increasing due to the aging of the population. The ligamentum flavum (LF) is a spinal ligament located in the interior of the vertebral canal, and hypertrophy of the LF, which causes the direct compression of the nerve roots and/or cauda equine, is a major cause of LSCS. Although there have been previous studies on LF hypertrophy, its pathomechanism remains unclear. The purpose of this study is to establish a relevant mouse model of LF hypertrophy and to examine disease-related factors. First, we focused on mechanical stress and developed a loading device for applying consecutive mechanical flexion-extension stress to the mouse LF. After 12 weeks of mechanical stress loading, we found that the LF thickness in the stress group was significantly increased in comparison to the control group. In addition, there were significant increases in the area of collagen fibers, the number of LF cells, and the gene expression of several fibrosis-related factors. However, in this mecnanical stress model, there was no macrophage infiltration, angiogenesis, or increase in the expression of transforming growth factor-β1 (TGF-β1), which are characteristic features of LF hypertrophy in LSCS patients. We therefore examined the influence of infiltrating macrophages on LF hypertrophy. After inducing macrophage infiltration by micro-injury to the mouse LF, we found excessive collagen synthesis in the injured site with the increased TGF-β1 expression at 2 weeks after injury, and further confirmed LF hypertrophy at 6 weeks after injury. Our findings demonstrate that mechanical stress is a causative factor for LF hypertrophy and strongly suggest the importance of macrophage infiltration in the progression of LF hypertrophy via the stimulation of collagen production.

    The aim of this study was to examine lower lumbar kinematics in cyclists with and without non-specific chronic low back pain (NS-CLBP) during a cross-sectional cycling field study. Although LBP is a common problem among cyclists, studies investigating the causes of LBP during cycling are scarce and are mainly focussed on geometric bike-related variables. Until now no cycling field studies have investigated the relationship between maladaptive lumbar kinematics and LBP during cycling. Eight cyclists with NS-CLBP classified as having a 'Flexion Pattern' (FP) disorder and nine age- and gender-matched asymptomatic cyclists were tested. Subjects performed a 2 h outdoor cycling task on their personal race bike. Lower lumbar kinematics was measured with the BodyGuard™ monitoring system. Pain intensity during and after cycling was measured using a numerical pain rating scale. The NS-CLBP (FP) subjects were significantly more flexed at the lower lumbar spine during cycling compared to healthy controls (p = 0.018), and reported a significant increase in pain over the 2 h of cycling (p posture between groups did not change over time. These findings suggest that a subgroup of cyclists with NS-CLBP (FP) demonstrate an underlying maladaptive motor control pattern resulting in greater lower lumbar flexion during cycling which is related to a significant increase in pain.

    Chronic back pain is often a result of coexisting pathologies; secondary causes of pain can become more apparent sources of pain once the primary pathology has been addressed. The objective of our study was to determine if there is an increase in diagnosis of Sacroiliac joint pain following a Lumbar Rhizotomy. A list of patients who underwent Lumbar Radiofrequency during a 6-month period in our clinic was generated. Records from subsequent clinic visits were reviewed to determine if a new diagnosis of SI joint pathology was made. In patients who underwent a recent Lumbar Rhizotomy procedure to treat facetogenic pain, the prevalence of Sacroiliac joint pain increased to 70%. We infer that there is a significant increase in the diagnosis of Sacroiliac joint syndrome following a Lumbar Rhizotomy, potentially due to unmasking of a preexisting condition. In patients presenting with persistent back pain after Lumbar Rhizotomy, the clinician must have a high degree of suspicion for latent Sacroiliac joint pain prior to attributing the pain to block failure. It would be prudent to use >80% relief of pain after a diagnostic medial branch block as a diagnostic criterion for facetogenic pain rather than the currently accepted >50% in order to minimize unmasking of preexisting subclinical pain from the SI joint.

    Lumbar degenerative kyphosis (LDK) is a subgroup of the flat-back syndrome and is most commonly caused by unique life styles, such as a prolonged crouched posture during agricultural work and performing activities of daily living on the floor. Unfortunately, LDK has been used as a byword for degenerative sagittal imbalance, and this sometimes causes confusion. The aim of this review was to evaluate the exact territory of LDK, and to introduce another appropriate term for degenerative sagittal deformity. Unlike what its name suggests, LDK does not only include sagittal balance disorder of the lumbar spine and kyphosis, but also sagittal balance disorder of the whole spine and little lordosis of the lumbar spine. Moreover, this disease is closely related to the occupation of female farmers and an outdated Asian life style. These reasons necessitate a change in the nomenclature of this disorder to prevent misunderstanding. We suggest the name "primary degenerative sagittal imbalance" (PDSI), which encompasses degenerative sagittal misalignments of unknown origin in the whole spine in older-age patients, and is associated with back muscle wasting. LDK may be regarded as a subgroup of PDSI related to an occupation in agriculture. Conservative treatments such as exercise and physiotherapy are recommended as first-line treatments for patients with PDSI, and surgical treatment is considered only if conservative treatments failed. The measurement of spinopelvic parameters for sagittal balance is important prior to deformity corrective surgery. LDK can be considered a subtype of PDSI that is more likely to occur in female farmers, and hence the use of LDK as a global term for all degenerative sagittal imbalance disorders is better avoided. To avoid confusion, we recommend PDSI as a newer, more accurate diagnostic term instead of LDK.

    Full Text Available The purpose of this paper is to show the importance and utility of swimming within rehabilitation and therapeutic programs for posture deficiencies, in our context for the rehabilitation of lumbar hyperlordosis. We consider that, by using exercises specific to swimming and means specific to acquiring swimming procedures, we will reduce the range of lumbar hyperlordosis. More precisely, we believe that, through exercises specific to swimming, we will reduce the range of lumbar hyperlordosis by at least 15 mm. Our study comprise three subjects (young girls, who suffer from lumbar hyperlordosis. For establishing the diagnostic, the following examinations and tests took place: anamnesis; somatoscopy; somatometry; muscular testing; specific tests (Schõber, “finger-floor”. The therapeutic program applied included the following: exercises for learning and consolidating the swimming procedures of crawl, backstroke, breaststroke and butterfly. The rehabilitation program lasted five months and a half; we had two sessions per week, each session of 35-40 minutes; water temperature ranged between 29 and 31 degrees Celsius. Initial testing showed that the lordosis amplitude was 70 mm for subject A.B., 60 mm for subject R.A. and 55 mm for subject S.A. At the end of research the results of the lordosis amplitude were 52 mm for subject A.B., 45 mm for subject R.A. and 40 mm for subject S.A. The conclusion of this study underlines that the early and correct intervention through individualized rehabilitation programs for lumbar hyperlordosis leads to a decrease in the lumbar curvature, down to physiological values. In addition, the means used for acquiring and consolidating swimming procedures can constitute important means in the rehabilitation process for lumbar hyperlordosis.

    A number of total disc arthroplasty devices have been developed. Some concern has been expressed that wear may be a potential failure mode for these devices, as has been seen with hip arthroplasty. The aim of this paper was to investigate the lubrication regimes that occur in lumbar total disc arthroplasty devices. The disc arthroplasty was modelled as a ball-and-socket joint. Elastohydrodynamic lubrication theory was used to calculate the minimum film thickness of the fluid between the bearing surfaces. The lubrication regime was then determined for different material combinations, size of implant, and trunk velocity. Disc arthroplasties with a metal-polymer or metal-metal material combination operate with a boundary lubrication regime. A ceramic-ceramic material combination has the potential to operate with fluid-film lubrication. Disc arthroplasties with a metal-polymer or metal-metal material combination are likely to generate wear debris. In future, it is worth considering a ceramic-ceramic material combination as this is likely to reduce wear.

    Lumbar puncture is a medical technique that physicians must learn and is, therefore, considered a basic medical procedure. The lumbar puncture simulators Lumbar-Kun (Lumbar Puncture Simulator) and Lumbar-Kun II (Lumbar Puncture Simulator II) (Kyoto Kagaku, Kyoto, Japan) are teaching aids designed for practicing spinal insertions. We describe and results of a lumbar puncture clerkship course, provided to 5th-year medical students during clinical clerkship activity. The aim of this study was to evaluate the effectiveness of the lumbar puncture clerkship course in the medical education program. Comprehension, technical achievement, and satisfaction were scored by students and instructors using a 6-point Likert scale. Scores for both comprehension and technical achievement were high, but technical achievement scores tended to be higher than comprehension scores. In addition, the scores students gave themselves were higher than the scores they were given by instructors. Student satisfaction was high. The lumbar puncture simulators, Lumbar-Kun and Lumbar-Kun II, achieved excellent overall impressions and represent useful tools for training in lumbar puncture procedures. In addition to the simulators, an appropriate preparatory text and a short lecture before training seemed to increase the educational effect of this lumbar puncture clerkship course for medical students.

    OBJECTIVE This study was designed with the following research objectives: 1) to determine the efficacy of facet fusion with recombinant human bone morphogenetic protein-2 (rhBMP-2) on an absorbable collagen sponge (ACS) in an ovine lumbar facet fusion model; 2) to radiographically and histologically compare the efficacy of lumbar facet fusion with rhBMP-2/ACS to facet fusion with an iliac crest bone graft (ICBG); and 3) to biomechanically compare lumbar facet fusion with rhBMP-2/ACS to lumbar posterolateral fusion (PLF) with ICBG. METHODS The efficacies of the 3 treatments to induce fusion were evaluated in an instrumented ovine lumbar fusion model. Eight sheep had 10 cm(3)/side ICBG placed as an onlay graft for PLF at L2-3. At the adjacent L3-4 level, 0.5 cm(3)/side ICBG was placed for facet fusion. Finally, 0.5 cm(3)/side rhBMP-2/ACS (0.43 mg/ml) was placed for facet fusion at L4-5. CT scans were obtained at 2, 4, and 6 months postoperatively with 2 reviewers conducting an evaluation of the 6-month results for all treated spinal levels. All 8 sheep were killed at 6 months, and all posterolateral instrumentation was removed at this time. The spines were then sectioned through L3-4 to allow for nondestructive unconstrained biomechanical testing of the L2-3 and L4-5 segments. All treated spinal levels were analyzed using undecalcified histology with corresponding microradiography. Statistical comparisons were made between the treatment groups. RESULTS The PLF with ICBG (ICBG PLF group) and the rhBMP-2 facet fusion (rhBMP-2 Facet group) treatment groups demonstrated similar levels of stiffness, with the rhBMP-2 Facet group having on average slightly higher stiffness in all 6 loading directions.

    Objective To evaluate the outcome of two methods for stabilization and fusion: posterolateral fusion and circumferential fusion involving posterior lumbar interbody fusion for lumbar stenosis with Grades 1 and 2 lumbar spondylolisthesis. Methods From April 1998 to April 2003, 45 patients suffering from lumbar stenosis with low degree lumbar spondylolisthesis treated in our hospital were retrospectively reviewed and assigned to two groups. Among them, 24 patients (group A) were treated with instrumented posterolateral fusion and 21 patients (group B) with instrumented circumferential fusion. The two groups were compared for clinical and radiological outcomes. Results All patients were followed up for 12 to 72 months. In group A, results showed preoperative clinical symptoms disappeared completely in 12 of 24 patients, and pain relief was seen in 91.7% (22/24). Two cases suffered from residual symptoms. Twenty-two cases obtained complete reduction of olisthy vertebral bodies, and anatomical reduction rate was 91.7%. No infection or neurological complication occurred in this group. In group B, results showed preoperative clinical symptoms disappeared completely in 13 of 21 patients, and pain relief was seen in 90. 5% ( 19/21 ). One case suffered from residual symptoms. Twenty cases obtained complete reduction of the olisthy vertebral bodies, and anatomical reduction rate was 95.2%. Four cases of infection or neurological complication occurred in this group. Both groups indicated no significant difference in clinical outcomes and anatomical reduction rate during followup. But group A had better intraoperative circumstances and postoperative outcome than group B, while group B had better postoperative parameters in X-ray of Angle of Slipping and Disc Index than group A.Conclusions The first choice of surgical method for lumbar stenosis with low degree lumbar spondylolisthesis is instrumented posterolateral fusion. Only when patients suffer from severe preoperative disc

    Lumbar multifidus muscles (LMM) are important for spinal motion and stability. Low back pain (LBP) is often associated with fat infiltration in LMM. An increasing fat infiltration of LMM may lead to lumbar dysfunction. The purpose of this study was to investigate whether there is a correlation between the severity of lumbar dysfunction and the severity of fat infiltration of LMM. In a cross-sectional study, 42 patients with acute or chronic LBP were recruited. Their MRI findings were visually rated and graded using three criteria for fat accumulation in LMM: Grade 0 (0-10%), Grade 1 (10-50%) and Grade 2 (>50%). Lumbar sagittal range of motion, dynamic upright and seated posture control, sagittal movement control, body awareness and self-assessed functional disability were measured to determine the patients' low back dysfunction. The main result of this study was that increased severity of fat infiltration in the lumbar multifidus muscles correlated significantly with decreased range of motion of lumbar flexion (p = 0.032). No significant correlation was found between the severity of fat infiltration in LMM and impaired movement control, posture control, body awareness or self-assessed functional disability. This is the first study investigating the relationship between the severity of fat infiltration in LMM and the severity of lumbar dysfunction. The results of this study will contribute to the understanding of the mechanisms leading to fat infiltration of LMM and its relation to spinal function. Further studies should investigate whether specific treatment strategies are effective in reducing or preventing fat infiltration of LMM.

    A relationship exists between lumbar paraspinal muscle fatigue and quadriceps muscle activation. The objective of this study was to determine whether hip and knee joint moments during jogging changed following paraspinal fatiguing exercise. Fifty total subjects (25 with self-reported history of low back pain) performed fatiguing, isometric lumbar extension exercise until a shift in EMG median frequency corresponding to a mild level of muscle fatigue was observed. We compared 3-dimensional external joint moments of the hip and knee during jogging before and after lumbar paraspinal fatigue using a 10-camera motion analysis system. Reduced external knee flexion, knee adduction, knee internal rotation and hip external rotation moments and increased external knee extension moments resulted from repetitive lumbar paraspinal fatiguing exercise. Persons with a self-reported history of LBP had larger knee flexion moments than controls during jogging. Neuromuscular changes in the lower extremity occur while resisting knee and hip joint moments following isolated lumbar paraspinal exercise. Persons with a history of LBP seem to rely more heavily on quadriceps activity while jogging.

    Lumbar burst fractures (L3–L5) represent a small percentage of all spinal fractures. The treatment of fractures involving the lumbar spine has been controversial. Lamina fractures may be complete or of the greenstick type. Dural tears and nerve root entrapment may accompany these lamina fractures. The aim of this retrospective study was to determine the incidence of dural tear in patients who had lumbar burst fractures with greenstick lamina fractures and the importance of these lamina fractures when choosing the optimum treatment. Twenty-six patients with 28 lumbar burst fractures were treated from 1995 through 2002. The average follow-up was 60 months (range 32–110 months). The male to female ratio was 21:5 and the mean age was 37 years (17–64). Dural tear was detected in seven (25%) out of 28 burst fractures. The functional outcome of the entire study group was assessed using the Smiley-Webster Scale. Good to excellent results were obtained in 24 (92%) of 26 patients. Lumbar burst fractures with greenstick lamina fractures occur mostly in the L2–L4 area. In the surgical treatment, any reduction manoeuvre will close the fracture and crush the entrapped neural elements. Therefore, it may be better to explore the greenstick lamina fracture whether there is any neural entrapment or not, before any reduction manoeuvre is attempted. PMID:16501977

    Patients with hyperhidrosis suffer from physical, social and mental discomfort which often cannot be treated sufficiently using conservative measures. A new percutaneous approach to sympathectomy using radiofrequency denervation has seemed to offer longer duration of action and less incidence of post sympathetic neuralgia. This article reports the authors' experience with sympathetic RF neurolysis in a 35 year old male with right unilateral lumbar hyperhidrosis. Under scopy guided localization of the lumbar spine sympathetic blockade with local anesthetics to L2-5 vertebral levels were performed as a diagnostic block. Lesion effectiveness is monitored by bilateral feet skin temperature measurement. Clinical effects produced by the first sympathetic ganglion block were sustained for 1 week and then RF neurolysis of lumbar sympathetic ganglion was performed to the same levels for a longer effect. The procedure was accomplished within 30 minutes and the patient was discharged within 2 hours after the procedure. Hyperhidrosis was relieved after the procedure and there were no postsympathectomy neuralgia and sexual dysfunction. The patient obtained improvement of lumbar hyperhidrosis at his first month of follow- up and was satisfied with the outcome. In conclusion, RF neurolysis of lumbar sympathetic ganglions is a safe and effective palliative procedure with minimal invasiveness for relieving excessive sweat secretion in patients with localized hyperhidrosis.

    To develop a novel method of spinal pedical stereotaxy by reverse engineering and rapid prototyping techniques, and to validate its accuracy by experimental and clinical studies. Methods: A 3D reconstruction model for the desired lumbar vertebra was generated by using the Mimics 10.11 software, and the optimal screw size and orientation were determined using the reverse engineering software. Afterwards, a drill template was created by reverse engi-neering principle, whose surface was the antitemplate of the vertebral surface. The drill template and its correspond-ing vertebra were manufactured using the rapid prototyping technique. Results: The accuracy of the drill template was con-firmed by drilling screw trajectory into the vertebral biomodel preoperatively. This method also showed its ability to cus-tomize the placement and size of each screw based on the unique morphology of the lumbar vertebra.The drill tem-plate fits the postural surface of the vertebra very well in the cadaver experiment. Postoperative CT scans for controlling the pedicle bore showed that the personalized template had a high precision in cadaver experiment and clinical application. No misplacement occurred by using the per-sonalized template. During surgery, no additional computer assistance was needed.Conclusions: The authors have developed a novel drill template for lumbar pedicle screw placement with good applicability and high accuracy. The potential use of drill templates to place lumbar pedicle screws is promising. Our methodology appears to provide an accurate technique and trajectory for pedicle screw placement in the lumbar spine.

    The present study aimed to evaluate the early effects of interspinous spacers on lumbar degenerative disease. The clinical outcomes of 23 patients with lumbar degenerative disease, treated using interspinous spacer implantation alone or combined with posterior lumbar fusion, were retrospectively studied and assessed with a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). Pre-operative and post-operative interspinous distance, disc space height, foraminal width and height and segmental lordosis were determined. The early effects and complications associated with the interspinous spacers were recorded. The surgical procedures performed with the in-space treatment were easy and minimally invasive. The VAS scores and ODI were improved post-operatively compared with pre-operatively. Significant changes in the interspinous distance, disc space height, foraminal width and height and segmental lordosis were noted. In-space treatment for degenerative lumbar disease is easy and safe, with good early effects. The in-space system provides an alternative treatment for lumbar degenerative disease.

    Abstract Radiographic features of consecutive lumbar spondylolisthesis were retrospectively analyzed in a total of 17 patients treated for this condition at the Third Hospital of Hebei Medical University from June 2005 to March 2012. To investigate the radiographic features, pelvic compensatory mechanisms, and possible underlying etiologies of consecutive lumbar spondylolisthesis. To the best of our knowledge, there is no previous report concerning the characteristics of consecutive lumbar spondylolisthesis. The Taillard index and the lumbar lordosis (LL), pelvic incidence (PI), sacrum slope (SS), and pelvic tilt (PT) were determined on lateral X-ray images, and the angular displacement was analyzed on flexion–extension X-ray images. Correlation between LL and various pelvic parameters and correlation between Taillard index and angular displacement were assessed by Pearson correlation analysis. A total of 20 cases of isthmic spondylolisthesis and 14 of degenerative spondylolisthesis were retrospectively studied in 17 patients. The Taillard index and the angular displacement in the lower vertebrae were both larger than those in the upper vertebrae. Statistical analysis revealed that LL was correlated with PI and PT, whereas PI was correlated with PT and SS. However, no correlation was identified between Taillard index and angular displacement. In consecutive lumbar spondylolisthesis, the degree of vertebral slip and the angular displacement of the lower vertebrae were both greater than those of the upper vertebrae, indicating that the compensatory mechanism of the pelvis plays an important role in maintaining sagittal balance.

    Full Text Available We report an unusual and complex case of spinal trauma in a 17-year-old boy who presented with a transverse sacral fracture associated with multiple-level lumbar fractures, paraparesis, and bladder involvement. A two-stage surgery was performed. The lumbar spine fractures were treated with posterior instrumented correction of displacements, followed by anterior instrumentation and fusion. The sacral fracture was left untreated. At 5-year followup, the patient had complete neurological recovery except for the right L5 root function. The long-segment lumbar fusion and the untreated displaced sacral fracture contributed to spinal imbalance, due to which the patient is now able to stand only in a crouched posture. Determining the optimal treatment for the case is presented due to the relative rarity of transverse sacral fracture and paucity of evidence-based treatment approaches. In patients with associated lumbar spine fractures that require extension of instrumentation to the upper lumbar spine, it is critical to restore sacropelvic alignment to achieve spinal balance. Adequate reduction of sacropelvic anatomy can be achieved with iliac screw fixation.

    ObjectS. To investigate the biomechanical aspects of etiology, pathology, clinical manifestation, diagnosis and surgical treatment of the lumbar spinal stenosis. Methods. A series of biomechanical methods, such as three-dimensional finite element models, threedimensional kinematic measurement, cadeveric evaluation, and imaging assessment was applied to correlate lumbar biomechanics and lumber spinal stenosls. Surgery of lumber spinal stenosis has been improved. Results.The stresses significantly concentrate on the posterolateral part of the annulus fibrcsms of disc, the posterior surface of vertebral body, the pedlcle, the interarticularis and the beet joints. This trend is intensified by disc degeneration and lumber backward extension. Posterior elcxnent resection has a definite effect upon the biomechanical behavior of lumbar vertebrae. The improved operations proved satisfactory. Conclusion. Stress concentration in the lumber vertebrae is of importance to the etiology of degenerative lumbar spinal stenosls, and disc degeneratkm is the initial key of this process. Than these will be aggravatnd by backward extension. Functloval radiography and myelography are of assistance to the diagnosis of the lumhar spinal stenosls. For the surgcal treatment of the lumber spinal stenosis, destruction of the posterior element should be avoid as far as possible based upon the thorough decmnpression. Maintaining the lumbar spine in flexion by fusion after decorapression has been proved a useftd method. When developmental spinal stenoals is combined with disc herniation, discectoray through laminotomy is recommend for decompression.

    This study sought to determine the outcomes of posterior lumbar interbody fusion (PLIF), via a unilateral approach, in selected patients who presented with unilateral leg pain and segmental instability of the lumbar spine. Patients with a single level of a herniated disc disease in the lumbar spine, unilateral leg pain, chronic disabling lower back pain (LBP), and a failed conservative treatment, were considered for the procedure. A total of 41 patients underwent a single-level PLIF using two PEEK (Poly-Ether-Ether-Ketone) cages filled with iliac bone, via a unilateral approach. The patients comprised 21 women and 20 men with a mean age of 41 years (range: 22 to 63 years). Two cages were inserted using a unilateral medial facetectomy and a partial hemilaminectomy. At follow-up, the outcomes were assessed using the Prolo Scale. The success of the fusion was determined by dynamic lumbar radiography and/or computerized tomography scanning. All the patients safely underwent surgery without severe complications. During a mean follow-up period of 26 months, 1 patient underwent percutaneous pedicle screw fixation due to persistent LBP. A posterior displacement of the cage was found in one patient. At the last follow up, 90% of the patients demonstrated satisfactory results. An osseous fusion was present in 85% of the patients. A PLIF, via a unilateral approach, enables a solid union with satisfactory clinical results. This preserves part of the posterior elements of the lumbar spine in selected patients with single level instability and unilateral leg pain.

    Gluteal perforator flaps (GPFs) are the most useful for gluteal region pressure sore reconstruction. However, application is difficult if the surrounding area has scar tissue from previous operations or trauma, especially with recurrent sores. We describe the use of modified lumbar artery perforator flaps when GPFs cannot be used. Between May 2009 and April 2014, 51 patients underwent gluteal pressure sore reconstructions with gluteal (n = 39) or modified lumbar artery (n = 12) perforator flaps. Patients in the modified lumbar artery perforator group had scar tissue from trauma or previous surgery. In this retrospective review, we analyzed patient age and sex, defect size and location, operative time, follow-up duration, immediate postoperative issues, flap necrosis, dehiscence, re-operation, donor-site morbidity and recurrence. Complications and clinical outcomes were compared between groups. We found no significant differences in patient demographics, surgical complications or clinical outcomes. There were eight cases of temporary congestion (20.51%) and four of partial flap necrosis (10.25%) in the gluteal perforator group. In the modified lumbar artery perforator group, there were three cases of temporary congestion (25%) and one of partial flap necrosis (8.33%). No pressure sores recurred during follow-up in either group. GPFs are the gold standards for gluteal pressure sores, but modified lumbar artery perforator flaps are relatively easy and useful when GPFs cannot be used due to scar tissue. © 2016 Royal Australasian College of Surgeons.

    Full Text Available The objective of this study was to evaluate the frequency of functional kyphosis and lumbar kyphosis in adolescent paddlers. A total of 140 paddlers (mean age: 13,67 ± 0,61 years participated in this study. The sagittal spinal curvatures (thoracic and lumbar curves in relaxed standing and in maximal trunk flexion with knees extended (sit-and-reach test were evaluated with an inclinometer. The analysis of angular values with respect to the normality references showed that 63% of athletes with normal thoracic curve in standing, while in maximal trunk flexion there were many athletes (91.2% with a moderate or slight kyphotic posture. With respect to lumbar curve, 68.5% of the subjects had normal values in standing, while 83.9% showed lumbar kyphotic postures in maximal trunk flexion. In conclusion, there was a high percentage of paddlers with normal angular values in relaxed standing, although when maximal trunk flexion with knees extended was performed there was a significant increase of kyphotic postures in both thoracic and lumbar curves. For this reason, the evaluation of sagittal spinal curvatures of paddlers is an important variable to include in training planning.

    Synovial cysts originating from the facet joint of the lumbar spine are a rare cause of radiculopathy. Surgical resection is considered to be the treatment of choice, although very little is known about the natural history of spinal synovial cysts. Only six cases have been published up to now concerning the spontaneous regression of a cyst without invasive therapy. We present the history of a patient suffering from sciatic pain caused by a synovial cyst at the level of L4/5, and we describe the spontaneous remission of the cyst, discussing the radiological and clinical findings and comparing our findings with respect to the current literature. The patient suffered from sciatic pain for 5 months without neurological deficits. Magnetic resonance tomography revealed a cystic structure adjacent to the facet joint L4/5. Presuming a synovial cyst, we scheduled surgery and at the same time started conservative treatment, including physical therapy and analgesic medication. The patient's condition improved significantly during conservative treatment, so that surgery was cancelled. A second magnetic resonance tomography showed that the cyst had dramatically shrunken, without any narrowing of the spinal canal. Up to now, synovial cysts of the lumbar spine have usually been treated operatively, but we and others have shown that spontaneous resolution of the cyst seems possible, so that extensive conservative treatment should always be considered as the first therapeutic option, provided that there are no severe neurological deficits.

    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.

    Based on 8 personal cases and a 81-cases review of literature, it's authors' opinion that cystic or solid masses issued form posterior lumbar articular process and called according to the cases synovial cyst, ganglion cyst, benign synovialoma, pigmented villonodular synovitis, are a single variety of benign degeneration of soft articular tissues. The cystic or solid feature of these masses depends upon the extent of their histiocytic granulomatous proliferation. They may be asymptomatic, accompany chronic lumbar pain or cause sciatica, seldom cauda equina syndrome. In case of sciatica, clinical picture rather consists of a narrow lateral recess than a discal protrusion. CT scan is the best investigation to get a right preoperative diagnosis. Postoperative prognosis is excellent and no anatomical recurrence has been reported.

    The authors developed an original procedure, modified fenestration with restorative spinoplasty (MFRS) for the treatment of lumbar spinal stenosis. The first step is to cut the spinous process in an L-shape, which is caudally reflected. This procedure allows easy access to the spinal canal, including lateral recesses, and makes it easy to perform a trumpet-style decompression of the nerve roots without violating the facet joints. After the decompression of neural tissues, the spinous process is anatomically restored (spinoplasty). The clinical outcomes at 2 years were evaluated using the Japanese Orthopaedic Association (JOA) scale and patients' satisfaction. Radiological follow-up included radiographs and CT. Between January 2000 and December 2002, 109 patients with neurogenic intermittent claudication with or without mild spondylolisthesis underwent MFRS. Of these, 101 were followed up for at least 2 years (follow-up rate 93%). The average score on the self-administered JOA scale in 89 patients without comorbidity causing gait disturbance improved from 13.3 preoperatively to 22.9 at 2 years' follow-up. Neurogenic intermittent claudication disappeared in all cases. The patients' assessment of treatment satisfaction was "satisfied" in 74 cases, "slightly satisfied" in 12, "slightly dissatisfied" in 2, and "dissatisfied" in 1 case. In 16 cases (18%), a minimum progression of slippage occurred, but no symptomatic instability or recurrent stenosis was observed. Computed tomography showed that the lateral part of the facet joints was well preserved, and the mean residual ratio was 80%. The MFRS technique produces an adequate and safe decompression of the spinal canal, even in patients with narrow and steep facet joints in whom conventional fenestration is technically demanding.

    STUDY DESIGN: A cross-sectional epidemiological survey of 4151 participants of the Copenhagen Osteoarthritis Study. OBJECTIVE: To identify prevalences and individual risk factors for degenerative lumbar spondylolisthesis. SUMMARY OF BACKGROUND DATA: The Copenhagen Osteoarthritis Study has...... registered health parameters since 1976. In 1993, standardized, lateral radiographs of the lumbar spine were recorded. There were 1533 men and 2618 women. METHODS: Statistical correlations were made between degenerative spondylolisthesis, and physical, occupational, and general epidemiological data. RESULTS......: A total of 254 cases of lumbar slip were found (males 2.7%, females 8.4%). In females, no significant relationship between age at menopause or childbirths and the presence of degenerative spondylolisthesis were found. In women, relationships between body mass index (BMI) in 1976 and L4 olisthesis (P = 0...

    This study was designed to assess the incidence of low back pain among Turkish coal miners and to investigate the relationship between angles of the lumbar spine and low back pain in coal miners. Fifty underground workers (Group I) and 38 age-matched surface workers (Group II) were included in the study. All the subjects were asked about low back pain in the past 5 years. The prevalence of low back pain was higher in Group I than in Group II (78.0%, 32.4%, respectively, P {lt} 0.001). The results of the study showed that low back pain occurred in 78.0% of Turkish coal miners. Although the nature of the occupation may have influenced coal miners' lumbar spinal curvature, lumbar angles are not a determinant for low back pain in this population. Further extensive studies involving ergonomic measurements are needed to validate our results for Turkish coal mining industry.

    The increasing adoption of minimally invasive techniques for spine surgery in recent years has led to significant advancements in instrumentation for lumbar interbody fusion. Percutaneous pedicle screw fixation is now a mature technology, but the role of expandable cages is still evolving. The capability to deliver a multiexpandable interbody cage with a large footprint through a narrow surgical cannula represents a significant advancement in spinal surgery technology. The purpose of this report is to describe a multiexpandable lumbar interbody fusion cage, including implant characteristics, intended use, surgical technique, preclinical testing, and early clinical experience. Results to date suggest that the multiexpandable cage allows a less invasive approach to posterior/transforaminal lumbar interbody fusion surgery by minimizing iatrogenic risks associated with static or vertically expanding interbody prostheses while providing immediate vertebral height restoration, restoration of anatomic alignment, and excellent early-term clinical results.

    Sex determination is critical for developing the biological profile of unidentified skeletal remains. When more commonly used elements (os coxa, cranium) for sexing are not available, methods utilizing other skeletal elements are needed. This study aims to assess the degree of sexual dimorphism of the lumbar vertebrae and develop discriminant functions for sex determination from them, using a sample of South African blacks from the Raymond A. Dart Collection (47 males, 51 females). Eleven variables at each lumbar level were subjected to univariate and multivariate discriminant function analyses. Univariate equations produced classification rates ranging from 57.7% to 83.5%, with the highest accuracies associated with dimensions of the vertebral body. Multivariate stepwise analysis generated classification rates ranging from 75.9% to 88.7%. These results are comparable to other methods for sexing the skeleton and indicate that measures of the lumbar vertebrae can be used as an effective tool for sex determination.

    Plain CT described fairly accurately the anatomy and lesions of the lumbar and sacral spines on their transverse sections. Since hernia of the intervertebral disc could be directly diagnosed by CT, indications of myelography could be restricted. Spinal-canal stenosis of the lumbar spine occurs because of various factors, and CT not only demonstrated the accurate size and morphology of bony canals, but also elucidated thickening of the joints and yellow ligament. CT was also useful for the diagnosis of tumors in the lumbar and sacral spines, visualizing the images of bone changes and soft tissues on the trasverse sections. But the diagnosis of intradural tumors required myelography and metrizamide CT. CT has become important for the diagnosis of spinal and spinal-cord diseases and for selection of the route of surgical arrival.

    Abstract Objective: The aim of the study was to evaluate the efficacy and safety of transforaminal lumbar interbody fusion (TLIF) versus posterolateral fusion (PLF) in degenerative lumbar spondylosis. Methods: A systematic literature review was performed to obtain randomized controlled trials (RCTs) and observational studies (OSs) of TLIF and PLF for degenerative lumbar spondylosis. Trials performed before November 2015 were retrieved from the Medline, EMBASE, Cochrane library, and Chinese databases. Data extraction and quality evaluation of the trials were performed independently by 2 investigators. A meta-analysis was performed using STATA version 12.0. Results: Two RCTs and 5 OSs of 630 patients were included. Of these subjects, 325 were in the TLIF and 305 were in the PLF group. Results showed that TLIF did not increase the fusion rate based on RCTs (relative risk [RR] = 1.06; 95% confidence interval [CI]: 0.95–1.18; P = 0.321), but increased it based on OSs (RR = 1.14; 95% CI: 1.07–1.23; P = 0.000) and overall (RR = 1.11; 95% CI: 1.05–1.18; P = 0.001) as compared with PLF. TLIF was able to improve the clinical outcomes based on 1 RCT (RR = 1.33; 95% CI: 1.11–1.59, P = 0.002) and overall (RR = 1.19; 95% CI: 1.07–1.33; P = 0.001), but not based on OSs (RR = 1.11; 95% CI: 0.97–1.27; P = 0.129) as compared with PLF. There were no differences between TLIF and PLF in terms of visual analogue scale, Oswestry Disability Index, reoperation, complications, duration of surgical procedure, blood loss, and hospitalization. Conclusions: In conclusion, evidence is not sufficient to support that TLIF provides higher fusion rate than PLF, and this poor evidence indicates that TLIF might improve only clinical outcomes. Higher quality, multicenter RCTs are needed to better define the role of TLIF and PLF. PMID:27749558

    The relation between height of lumbar discs (measured from lateral radiographic views) and disc degeneration (classified from MR images) deserves attention in view of the wide, often parallel or interchanged use of both methods. The time sequence of degenerative signs and decrease of disc height is controversial. To clarify the issue, this cross-sectional study documents the relation between disc degeneration and disc height in a selected cohort. Forty-three subjects were selected at random from a cohort examined for potential disc-related disease caused by long-term lifting and carrying. From each subject a lateral radiographic view of the lumbar spine as well as findings from an MR investigation of (in most cases) levels T12/L1 to L5/S1 were available; thus, n = 237 lumbar discs were available for measurement and classification. Disc height was measured from the radiographic views with a new protocol compensating for image distortion and permitting comparison with normal, age- and gender-appropriate disc height. Degeneration as well as disc height were classified twice from MR images by independent observers in a blinded fashion. Disc degeneration classified from MR images is not related to a measurable disc height loss in the first stage of degeneration, whereas progressive degeneration goes along with progressive loss of disc height, though with considerable interindividual variation. Loss of disc height classified from MR images is on average compatible with loss of disc height measured from radiographs. In individual discs, however, classification of height loss from MR images is imprecise. The first sign of disc degeneration (a moderate loss of nucleus signal) precedes disc height decrease. As degeneration progresses, disc height decreases. Disc height decrease and progress of degeneration, however, appear to be only loosely correlated. (orig.)

    This study reviews the outcomes and revision rates of degenerative lumbar fusion surgery using cortical trajectory pedicle screws in lieu of traditional pedicle screw instrumentation. Pedicle screw fixation can be a challenge in patients with low bone mineral density. Wide posterior approaches to the lumbar spine exposing lateral to the facet joints and onto transverse processes causes an additional degree of muscular damage and blood loss not present with a simple laminectomy. A cortical bone trajectory pedicle screw has been proposed as an alternative to prevent screw pullout and decrease the morbidity associated with the wide posterior approach to the spine. We present a series of eight consecutive patients using a cortical bone trajectory instead of traditional pedicle screw fixation for degenerative conditions of the lumbar spine. A retrospective review of our institutional registry data identified eight patients who had cortical screws placed with the assistance of O-arm Stealth navigation (Medtronic Sofamor Danek, Memphis, TN, USA) from 2010-2013. We analyzed the need for revision, the maintenance of reduction and the incidence of screw pullout or breakage. Our review demonstrated that two of eight patients were revised at an average of 12months. The reasons for these revisions were pseudarthrosis and caudal adjacent segment failure. All patients who were revised had frank screw loosening. We present early clinical results of a new technique that has been shown to have a better fixation profile in laboratory testing. Our less than favorable early clinical results should be interpreted with caution and highlight important technical issues which should be considered. Copyright © 2015 Elsevier Ltd.

    Pasi J Eskola

    Full Text Available OBJECTIVE: Low back pain is associated with lumbar disc degeneration, which is mainly due to genetic predisposition. The objective of this study was to perform a systematic review to evaluate genetic association studies in lumbar disc degeneration as defined on magnetic resonance imaging (MRI in humans. METHODS: A systematic literature search was conducted in MEDLINE, MEDLINE In-Process, SCOPUS, ISI Web of Science, The Genetic Association Database and The Human Genome Epidemiology Network for information published between 1990-2011 addressing genes and lumbar disc degeneration. Two investigators independently identified studies to determine inclusion, after which they performed data extraction and analysis. The level of cumulative genetic association evidence was analyzed according to The HuGENet Working Group guidelines. RESULTS: Fifty-two studies were included for review. Forty-eight studies reported at least one positive association between a genetic marker and lumbar disc degeneration. The phenotype definition of lumbar disc degeneration was highly variable between the studies and replications were inconsistent. Most of the associations presented with a weak level of evidence. The level of evidence was moderate for ASPN (D-repeat, COL11A1 (rs1676486, GDF5 (rs143383, SKT (rs16924573, THBS2 (rs9406328 and MMP9 (rs17576. CONCLUSIONS: Based on this first extensive systematic review on the topic, the credibility of reported genetic associations is mostly weak. Clear definition of lumbar disc degeneration phenotypes and large population-based cohorts are needed. An international consortium is needed to standardize genetic association studies in relation to disc degeneration.

    Careful review of published evidence has led to the postulate that the degree of lumbar lordosis may possibly influence the development and progression of spinal osteoarthritis, just as misalignment does in other joints. Spinal degeneration can ensue from the asymmetrical distribution of loads. The resultant lesions lead to a domino- like breakdown of the normal morphology, degenerative instability and deviation from the correct configuration. The aim of this study is to investigate whether a relationship exists between the sagittal alignment of the lumbar spine, as it is expressed by lordosis, and the presence of radiographic osteoarthritis. 112 female subjects, aged 40-72 years, were examined in the Outpatients Department of the Orthopedics' Clinic, University Hospital of Heraklion, Crete. Lumbar radiographs were examined on two separate occasions, independently, by two of the authors for the presence of osteoarthritis. Lordosis was measured from the top of L1 to the bottom of L5 as well as from the top of L1 to the top of S1. Furthermore, the angle between the bottom of L5 to the top of S1 was also measured. 49 women were diagnosed with radiographic osteoarthritis of the lumbar spine, while 63 women had no evidence of osteoarthritis and served as controls. The two groups were matched for age and body build, as it is expressed by BMI. No statistically significant differences were found in the lordotic angles between the two groups There is no difference in lordosis between those affected with lumbar spine osteoarthritis and those who are disease free. It appears that osteoarthritis is not associated with the degree of lumbar lordosis.

    The uncommon variant of degenerative hip joint disease, termed rapidly progressive osteoarthritis, and highlighted by severe joint space loss and osteochondral disintegration, is well established. We present a similar unusual subset in the lumbar spine termed destructive discovertebral degenerative disease (DDDD) with radiological features of vertebral malalignment, severe disc resorption, and "bone sand" formation secondary to vertebral fragmentation. Co-existing metabolic bone disease is likely to promote the development of DDDD of the lumbar spine, which presents with back pain and sciatica due to nerve root compression by the "bone sand" in the epidural space. MRI and CT play a complimentary role in making the diagnosis.

    Background To evaluate the effect of spondylolisthesis on lumbar lordosis on the OSI (Jackson; Orthopaedic Systems Inc.) frame. Restoration of lumbar lordosis is important for maintaining sagittal balance. Physiologic lumbar lordosis has to be gained by intraoperative prone positioning with a hip extension and posterior instrumentation technique. There are some debates about changing lumbar lordosis on the OSI frame after an intraoperative prone position. We evaluated the effect of spondylolisthesis on lumbar lordosis after an intraoperative prone position. Methods Sixty-seven patients, who underwent spinal fusion at the Department of Orthopaedic Surgery of Gwangmyeong Sungae Hospital between May 2007 and February 2012, were included in this study. The study compared lumbar lordosis on preoperative upright, intraoperative prone and postoperative upright lateral X-rays between the simple stenosis (SS) group and spondylolisthesis group. The average age of patients was 67.86 years old. The average preoperative lordosis was 43.5° (± 14.9°), average intraoperative lordosis was 48.8° (± 13.2°), average postoperative lordosis was 46.5° (± 16.1°) and the average change on the frame was 5.3° (± 10.6°). Results Among all patients, 24 patients were diagnosed with simple spinal stenosis, 43 patients with spondylolisthesis (29 degenerative spondylolisthesis and 14 isthmic spondylolisthesis). Between the SS group and spondylolisthesis group, preoperative lordosis, intraoperative lordosis and postoperative lordosis were significantly larger in the spondylolisthesis group. The ratio of patients with increased lordosis on the OSI frame compared to preoperative lordosis was significantly higher in the spondylolisthesis group. The risk of increased lordosis on frame was significantly higher in the spondylolisthesis group (odds ratio, 3.325; 95% confidence interval, 1.101 to 10.039; p = 0.033).

    We studied the accuracy of MRI in lumbar disc herniation, comparing the results with the operative findings in the assessment of the rupture of the posterior longitudinal ligament (PLL), and type of herniation. The MRI findings in 47 subjects who were operated on for lumbar disc herniation were retrospectively studied. The accuracy rate was 75.2% for the rupture of the PLL and 40.4% for the type of herniation respectively. It was hard to differentiate subligamentous extrusion from transligamentous extrusion on MRI.

    Lumbar hernias are rare defects in the posterolateral abdominal wall that may be congenital or acquired. We present a case of laparoscopic approach to repair an acquired inferior triangle (Petit) lumbar hernia in a woman by using polytetrafluoroethylene mesh. The size of the hernia was 8 x 10 cm. The length of her hospital stay was 2 days. The patient resumed normal activities in less than 2 weeks. The main advantage of this approach is excellent operative visualization, thus avoiding injury to structures near the hernia during repair. Patients benefit from a minimally invasive approach with less pain, shortened hospital course, less analgesic requirements, better cosmetic result, and minimal life-style interference.

    Lumbar hernias are rare, resulting from protrusion through the posterior abdominal wall that may be congenital, acquired or spontaneous. They very rarely present with acute bowel obstruction. We present a case of incarcerated small bowel within a spontaneous inferior (Petit's) lumbar hernia, treated by early open repair with mesh insertion. This case highlights the importance of thorough clinical examination and a high index of suspicion, even in the absence of previous surgery around the anatomical site of the suspected hernia, in order to effect an early repair before the onset of ischaemia in incarcerated contents.

    Objectives: To investigate whether there is any relationship between the prevalence and the dimension of OLF and the presence and degree of facet joint degeneration. In addition, it revealed the prevalence and distribution of lumbar OLF with regard to age and spinal levels. Methods: The stone protocol abdominal CT images of 114 patients were retrospectively analyzed. Presence of OLF, degenerative changes in the posterior vertebral elements was evaluated on axial CT images and incidence for each finding was determined. Additionally, the degree of facet joint degeneration and size of OLF was evaluated and recorded. All findings were also grouped based on age and lumbar level. Results: OLF has been observed in 40 (35%) individuals at 76 (13%) lumbar levels. OLF has been most frequently encountered at the upper lumbar levels. Its frequency and size showed correlation to increased age. Frequency of OLF correlated with the presence of degenerative changes of in the posterior elements (p < 0.001). There was an association between the OLF size and the presence (p = 0.001) and degree of the degeneration in the posterior elements. There was no lumbar level case where the degree of OLF would lead to enough narrowing to be symptomatic. Conclusions: OLF prevalence and sizes increase parallel to age. Posterior elements' degenerative changes facilitate OLF development. A close relation exists between OLF size and facet joint degeneration. A direct relationship exists between OLF size and the degree of posterior elements degeneration. It is highly probable for lumbar level OLF size to be insufficient to cause any symptoms.

    Full Text Available Abstract Background Hueter-Volkmann's law regarding growth modulation suggests that increased pressure on the end plate of bone retards the growth (Hueter and conversely, reduced pressure accelerates the growth (Volkmann. Literature described the same principle in Rat-tail model. Human spine and its deformity i.e. scoliosis has also same kind of pattern during the growth period which causes wedging in disc or vertebral body. Methods This cross sectional study in 150 patients of adolescent idiopathic scoliosis was done to evaluate vertebral body and disc wedging in scoliosis and to compare the extent of differential wedging of body and disc, in thoracic and lumbar area. We measured wedging of vertebral bodies and discs, along with two adjacent vertebrae and disc, above and below the apex and evaluated them according to severity of curve (curve 30° to find the relationship of vertebral body or disc wedging with scoliosis in thoracic and lumbar spine. We also compared the wedging and rotations of vertebrae. Results In both thoracic and lumbar curves, we found that greater the degree of scoliosis, greater the wedging in both disc and body and the degree of wedging was more at apex supporting the theory of growth retardation in stress concentration area. However, the degree of wedging in vertebral body is more than the disc in thoracic spine while the wedging was more in disc than body in lumbar spine. On comparing the wedging with the rotation, we did not find any significant relationship suggesting that it has no relation with rotation. Conclusion From our study, we can conclude that wedging in disc and body are increasing with progression on scoliosis and maximum at apex; however there is differential wedging of body and disc, in thoracic and lumbar area, that is vertebral body wedging is more profound in thoracic area while disc wedging is more profound in lumbar area which possibly form 'vicious cycle' by asymmetric loading to spine for the

    If sitting postures influence the risk of developing low back pain then it is important that quantification of sedentary work activities and simultaneous measurement of lumbar postural characteristics takes place. The objective of this study was to develop a system for identifying activities and their associated lumbar postures using fibre optic goniometers (FOGs). Five student subjects wore two FOGs attached to the lumbar spine and hip for 8 min while being recorded using a video camera when sitting, standing and walking. Observer Software was used to code the video recording, enabling the sagittal movement characteristics of each FOG to be described for individual activities. Results indicated that each activity produced unique data, and could be independently identified from their motion profiles by three raters (k = 1). The data will be used to develop algorithms to automate the process of activity detection. This system has the potential to measure behaviour in non-clinical settings.

    2014-03-01

    Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) is commonly used for the treatment of a variety of degenerative spine disorders. Recently, steerable interbody cages have been developed which potentially allow for greater restoration of lumbar lordosis. Here we describe a technique and radiographic results following minimally invasive placement of steerable cages through a bilateral approach. A retrospective review was conducted of the charts and radiographs of 15 consecutive patients who underwent 19 levels of bilateral MIS-TLIF with the placement of steerable cages. These were compared to 10 patients who underwent 16 levels of unilateral MIS-TLIF with the placement of bullet cages. The average age, body mass index, distribution of the levels operated and follow-up were similar in both groups. The average height of the steerable cage placed was 10.9 mm compared to 8.5mm for bullet cages. The preoperative focal Cobb's angle per level was similar between both groups with a mean of -5.3 degrees for the steerable cage group and -4.8 degrees for the bullet cage group. There was a significant improvement in postoperative Cobb's angle after placement of a steerable cage with a mean of -13.7 (p<0.01) and this persisted at the last follow-up with -13 degrees (p<0.01). There was no significant change in Cobb's angle after bullet cage placement with -5.7 degrees postoperatively and a return to the baseline preoperative Cobb's angle of -4.8 at the last follow-up. Steerable cage placement for MIS-TLIF improves focal lordosis compared to bullet cage placement.

    OBJECTIVE Lateral lumbar interbody fusion (LLIF) has emerged as a popular method for lumbar fusion. In this study the authors aimed to quantify the biomechanical stability of an interbody implant inserted using the LLIF approach with and without various supplemental fixation methods, including an interspinous plate (IP). METHODS Seven human cadaveric L2-5 specimens were tested intact and in 6 instrumented conditions. The interbody implant was intended to be used with supplemental fixation. In this study, however, the interbody was also tested without supplemental fixation for a relative comparison of these conditions. The instrumented conditions were as follows: 1) interbody implant without supplemental fixation (LLIF construct); and interbody implant with supplemental fixation performed using 2) unilateral pedicle screws (UPS) and rod (LLIF + UPS construct); 3) bilateral pedicle screws (BPS) and rods (LLIF + BPS construct); 4) lateral screws and lateral plate (LP) (LLIF + LP construct); 5) interbody LP and IP (LLIF + LP + IP construct); and 6) IP (LLIF + IP construct). Nondestructive, nonconstraining torque (7.5 Nm maximum) induced flexion, extension, lateral bending, and axial rotation, whereas 3D specimen range of motion (ROM) was determined optoelectronically. RESULTS The LLIF construct reduced ROM by 67% in flexion, 52% in extension, 51% in lateral bending, and 44% in axial rotation relative to intact specimens (p < 0.001). Adding BPS to the LLIF construct caused ROM to decrease by 91% in flexion, 82% in extension and lateral bending, and 74% in axial rotation compared with intact specimens (p < 0.001), providing the greatest stability among the constructs. Adding UPS to the LLIF construct imparted approximately one-half the stability provided by LLIF + BPS constructs, demonstrating significantly smaller ROM than the LLIF construct in all directions (flexion, p = 0.037; extension, p < 0.001; lateral bending, p = 0.012) except axial rotation (p = 0

    The authors report on 2 cases of anterior dislocation of the Maverick lumbar disc prosthesis, both occurring in the early postoperative period. These cases developed after experience with more than 50 uneventful cases and were therefore thought to be unrelated to the surgeon's learning curve. No similar complications have been previously reported. The anterior Maverick device has a ball-and-socket design made of cobalt-chromium-molybdenum metal plates covered with hydroxyapatite. The superior and inferior endplates have keels to resist translation forces. The patient in Case 1 was a 52-year-old man with severe L4-5 discogenic pain; and in Case 2, a 42-year-old woman with disabling L4-5 and L5-S1 discogenic back pain. Both patients were without medical comorbidities and were nonsmokers with no risk factors for osteoporosis. Both had undergone uneventful retroperitoneal approaches performed by a vascular access surgeon. Computed tomography studies on postoperative Day 2 confirmed excellent prosthesis placement. Initial recoveries were uneventful. Two weeks postoperatively, after stretching (extension or hyperextension) in bed at home, each patient suffered the sudden onset of severe abdominal pain with anterior dislocation of the Maverick prosthesis. The patients were returned to the operating room and underwent surgery performed by the same spinal and vascular surgeons. Removal of the Maverick prosthesis and anterior interbody fusion with a separate cage and plate were performed. Both patients had recovered well with good clinical and radiological recovery at the 6- and 12-month follow-ups. Possible causes of the anterior dislocation of the Maverick prosthesis include the following: 1) surgeon error: In both cases the keel cuts were neat, and early postoperative CT confirmed good placement of the prosthesis; 2) equipment problem: The keel cuts may have been too large because the cutters were worn, which led to an inadequate press fit of the implants; 3) prosthesis

    , intradural-extramedullary lumbar tumors, especially schwannomas, can be completely and safely resected through a less-invasive interlaminar approach using a microscope, or a microscope in addition to an endoscope when necessary. This approach was advantageous because it caused even less bone destruction, resulting in better postoperative spinal stability, no need for facetectomy and fusion, and quicker functional recovery for the patients. Individualized surgical planning according to preoperative radiological findings is key to a successful microsurgical resection of these lesions through the interlaminar space.

    2017-01-01

    Introduction In reviewing a larger group of osteoporotic vertebral compression fractures (VCFs), we found that the overall incidence of sacral insufficiency fractures (SIFs) is higher than commonly reported values. This is especially seen in patients with previous or concurrent lumbar VCFs and also in a subgroup that had lumbar stenosis or hip arthroplasty. The altered biomechanics due to associated lumbar stenosis or hip arthroplasty lead to increased mechanical stress on already weakened and deficient sacral alae, which are more vulnerable to osteoporotic weakening than other parts of the sacrum. Materials & methods We studied an overall population of patients with VCF seen clinically and separated the patients into the following groups: patients not previously treated, patients treated with vertebroplasty or kyphoplasty at one or more levels, and patients diagnosed with sacral fractures and treated with vertebroplasty or kyphoplasty. We wanted to see if a pattern existed among the patients who had sacral symptoms, were diagnosed with sacral insufficiency fractures, and subsequently underwent sacroplasty. Results In a review of 79 consecutive patients, over a 24-month period, with VCF who underwent surgical treatment, there were 10 patients who also had sacral insufficiency fractures. Four of the patients had sacral insufficiency fractures without VCF. None of the patients with sacral insufficiency fractures were on treatment for osteoporosis at the time of diagnosis. The following symptoms indicated SIF: lower sacral pain (n = 10), buttock pain (n = 7), lateral hip pain (n = 5), and groin pain radiating to the thigh (n = 4). The average time to diagnose SIF was two months after the onset of pain. Conclusions Sacral insufficiency fractures are a frequent cause of both acute and chronic pain; however, they are often missed by the majority of physicians. The frequency of undetected sacral fractures is high. This is due to a number of potential pitfalls

    We determined the angular range of motion and the relative timing of displacement in the thorax, lumbar spine, and pelvis in the transverse plane during treadmill walking at three velocities. Nine healthy young females walked on a treadmill for three minutes at 0.40, 0.93, and 1.47 m/s. The position of seven reflective markers and three rigs placed on the thorax, lumbar spine, and pelvis were recorded at 200 Hz by an eight-camera motion capture system. As gait velocity increased, stride length increased, cycle time decreased, and angular displacement in the thorax and L1 decreased but increased at the pelvis and L5 (all P thorax (P thorax and L1 and L3 were in-phase for shorter duration as gait velocity increased, and this reduction was especially large, approx. 32% (P thorax and pelvis. As gait velocity increased, the pelvis rotated earlier, causing the shortening of in-phase duration between thorax and pelvis. These data suggest that, as gait velocity increases, pelvis rotation dictates trunk rotation in the transverse plane during gait in healthy young females.

  5. The Application of Parallel Robotics to Investigate the Effect of Lumbar Bracing on Trunk Muscle Activity

    2010-01-01

    Full Text Available Lumbar bracing is prescribed frequently for disability caused by low back pain; however, investigations into this practice demonstrate a range of patient outcomes. This inconsistency may arise from the practice of employing voluntary, single-axis trunk movements when investigating braces. Alternatively, this study employed a parallel robot to create a standardised, multi-axis testing environment. Surface electromyographic (sEMG data were collected from the trunk of 24 asymptomatic participants, who were seated on the robot, tilted to 15°, then circumducted while attempting to maintain an upright posture. Multiple trials were performed for three randomised conditions: non-braced, soft-material brace and stiff-material brace. As expected, the sEMG activity was significantly reduced in the majority of muscle responses (201/240. Unexpectedly, a paradoxical increase in the sEMG activity was observed in 39/240 responses. While lumbar bracing reduces the sEMG activity on average, these data suggest the existence of an infrequent paradoxical response that may provide a possible explanation for the discordant results observed in previous bracing investigations.

    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.

    A ligamento-muscular protective reflex in the lumbar spine was demonstrated in a feline model. Stimulating electrodes were applied to the supraspinous ligament between several lumbar vertebra (L1 to L6) while recording myoelectric discharge from the paraspinal muscles at the L3, L4 and L5, bilaterally. Electromyographic (EMG) activity was present in the paraspinal muscles bilaterally, upon stimulation of the supraspinous ligament, in six preparations. The EMG discharge was strongest in the muscles one level below that of the stimulated ligament, whereas weaker EMG signals were recorded from as far as two levels above and below. The mean time delay between the application of the stimulus to the ligament to the resulting EMG ranged from 2.52 to 2.77 ms at all levels. Stimulation of the supraspinous ligament in the L6 segment resulted in a weak reflex response, and stimulation in the L7 segment did not produce any EMG activity. It was concluded that mechanoreceptors in the supraspinous ligament at the L1/6 levels may initiate sensory signals upon strain of the ligament, during flexion. This, in turn, causes contraction of the paraspinal muscles, bilaterally, to extend the spine and prevent possible damage to the ligament while maintaining stability. The results may add to the understanding of low back pain, and to the formulation of surgical procedures which could spare the neural supply of the ligament, allowing advanced physiotherapeutic modalities to be implemented for post-surgical rehabilitation.

    Cycling is a daily activity that needs a high demand of human-bicycle fitness. However, studies into the fitness or ergonomic aspects are very little. In this study, the simulated 20 min bicycling test were performed by 26 male participants under 5 handle height conditions. Body joint angles and external cervical/lumbar spine lordosis were measured at the initial and cycling after 20 min. Results show that different handle heights did cause various trunk inclinations. Trunk inclination was negatively and positively correlated with lumbosacral angle (r = -0.620, p < 0.001) and cervical angle (r = 0.510, p < 0.001), respectively. In this study, regression models were also developed to predict the internal cervical and lumbar spine movements by external trunk inclination and head extension, respectively. The explanatory abilities for the variance of the models were 67.2% for LSA and 82.8% for CE prediction. This can be used to understand the cyclist's spine movements while field study of bicycling.

    The authors successfully treated a rare case of pigmented villonodular synovitis (PVNS) that originated from the lumbar facet joint (L4-5). A 43-year-old man presented with a complaint of left severe sciatica causing difficulty in walking. Magnetic resonance imaging (MRI) demonstrated an extradural mass on the left side at L4 and the mass compressed the dural tube and was continuous with the left L4-5 facet joint. A computed tomography myelogram revealed an extradural defect of contrast medium at the L4 level and an erosion of the L4 lamina. A total synovectomy with unilateral osteoplastic laminectomy was performed. The histological findings were a diagnosis of PVNS. The patient’s symptoms resolved completely and the MRI at postoperative 3 years demonstrated no recurrence of PVNS. It is important to totally remove the synovium, which is the origin of PVNS in order to prevent the recurrence. We think that our procedure is reasonable and adequate for lumbar PVNS. PMID:17566795

    Full Text Available Introduction Chronic low back pain is a degenerative rheumatic disease and is characterized by various symptoms and clinical signs. Balneotherapy Balneotherapy represents a therapy by various hot or warm baths in natural mineral waters of specific physical and chemical characteristics. When used externally, they have mechanical, chemical and thermic effects. Balneotherapy of lumbar syndrome includes: individual baths, swimming in the pool, hydrokinesitherapy, underwater massage, underwater extension, mud therapy, mud baths. The therapy should be closely monitored for optimal efficacy and it is necessary to examine: functional status of the lumbosacral region, general functional status (level of activity, lower extremities, pain measurement, use of non-steroid anti-rheumatic and analgesic agents. In order to follow-up the effects of therapy and establish the prognosis it is important to perform: detailed anamnesis, anthropometrics measurements, socio-epidemiological research, clinical examinations. Conclusion Lumbar syndrome is usually caused by a degenerative disease of the spinal column. More than 25% of people under 45 years of age are unable to work due to chronic low back pain. That is why preventive measures, prompt diagnosis and adequate therapy are of utmost importance.

    Full Text Available Nontraumatic anterior subluxation and dislocation of the hip joint are extremely rare. A 58-year-old woman presented to our outpatient clinic with left hip pain with a duration of 15 years. There was no history of trauma or other diseases. Her hip pain usually occurred only on walking and not at rest. Physical examinations demonstrated no tenderness in the hip joint. The range of motion of both hip joints was almost normal. Laxity of other joints was not observed. The bone mineral density of the lumbar spine and proximal femur confirmed a diagnosis of osteoporosis. A plain radiograph showed osteoarthritic changes of the hip joints, severe posterior pelvic tilt, and superior displacement of both femoral heads, especially in a standing position. Three-dimensional computed tomography (3DCT revealed anterior subluxation of both femoral heads. Seven years after the initial visit, both hip joints showed progression to severe osteoarthritis. Although the exact cause remains unclear, lumbar kyphosis, posterior pelvic tilt, and a decrease in acetabular coverage may have influenced the current case. We should be aware of these factors when we examine patients with hip osteoarthritis.

    Full Text Available Lumbosacral region of the body not only protects the spinal cord and related structures but also transmit the body weight to lower extremity and maintains the body posture. Sacralization of the 5 th lumbar vertebrae, is a congenital vertebral anomaly of the lumbosacral region and may be unilateral or bilateral. Although, sacralization is not a serious anomaly, perhaps no more than an anatomical variant, the fusion of the lumbrosacral joint may cause low back pain, disc herniation, cervical ribs, Bertollotti’ s syndrome and difficulty during labor. To highlight the complication of sacralization and its related impact on the body, we report a case of complete fusion of 5 th lumbar vertebra with sacrum ( sacralization . The relationship between incidence of sacrali zation with low back pain is debatable but still the present study may help anatomists, clinicians and surgeons to know the complications of sacralization and its impact on the body that in turn help in diagnostic and therapeutic management of illness arou nd lumbosacral region. Future studies need to focus on identifying other parameters that are relevant to distinguishing lumbosacral variations and associated disorders.

    The aim of this article is to introduce a technique for lumbar intervertebral fusion that incorporates mobile microendoscopic discectomy (MMED) for lumbar degenerative disc disease. Minimally invasive transforaminal lumbar interbody fusion is frequently performed to treat degenerative diseases of the lumbar spine; however, the scope of such surgery and vision is limited by what the naked eye can see through the expanding channel system. To expand the visual scope and reduce trauma, we perform lumbar intervertebral fusion with the aid of a MMED system that provides a wide field through freely tilting the surgical instrument and canals. We believe that this technique is a good option for treating lumbar degenerative disc disease that requires lumbar intervertebral fusion.

    Flexion relaxation (FR) is characterized by the lumbar erector spinae (LES) becoming myoelectrically silent near full trunk flexion. This study was designed to: (1) determine if decreasing the lumbar moment during flexion would induce FR to occur earlier; (2) characterize thoracic and abdominal muscle activity during FR. Ten male participants performed four trunk flexion/extension movement conditions; lumbar moment was altered by attaching 0, 5, 10, or 15lb counterweights to the torso. Electromyography (EMG) was recorded from eight trunk muscles. Lumbar moment, lumbar flexion and trunk inclination angles were calculated at the critical point of LES inactivation (CPLES). Results demonstrated that counterweights decreased the lumbar moment and lumbar flexion angle at CPLES (pactive throughout flexion. Abdominal muscles activated at the same instant as CPLES, except in the 15lb condition where abdominal muscles activated before CPLES resulting in a period of increased co-contraction.

    Degenerative cysts of the lumbar spine encompass a heterogeneous group of cystic lesions that are presumed to share a common aetiology. Some of these cysts may be incidental findings, whereas others may produce acute or chronic symptoms. These cysts have been categorized using various combinations of topographic and pathological characteristics and by their attachment to or communication with a specific spinal structure.

    Conclusions: The incidence of postoperative ASD (up to 30% is greater following either open or MIS instrumented lumbar fusions (e.g., TLIF/PLIF, while decompressions with noninstrumented fusions led to a much smaller 5.6% risk of ASD. Other findings included: MIS instrumented fusions contributed to higher perioperative complication rates, and dynamic stabilization did not protect against ASD.

    Full Text Available Lumbar nerve root block is a common modality used in the management of radiculopathy. Its complications are rare and usually minor. Despite its low morbidity, significant acute events can occur. Pneumocephalus is an accumulation of air in the intracranial space. It indicates a violation of the dura or the presence of infection. The object of this report is to describe the case of a patient with intraventricular pneumocephalus and bacterial meningitis after lumbar nerve root block. A 70-year-old female was brought into emergency department with severe headache and vomiting which developed during her sleep. She had received lumbar nerve block for her radiculopathy one day before her presentation. Cranial computed tomography scan revealed a few hypodense lesions in her left lateral ventricle frontal horn and basal cistern indicating ventricular pneumocephalus. Five hours later, she developed sudden hearing loss. Cerebrospinal fluid analysis showed bacterial meningitis, and she was treated with high dose steroid and antibiotics. However, her impaired hearing as a sequela from meningitis was persistent, and she is still in follow-up. Intracranial complications of lumbar nerve root block including meningitis and pneumocephalus can occur and should be considered as high-risk conditions that require prompt intervention.

    We describe our endoscopic lumbar sympathectomy technique and our early experience using it to treat plantar hyperhidrosis. We reviewed 20 lumbar sympathectomies performed in our vascular unit for plantar hyperhidrosis in 10 patients from 2011 and 2014. Demographics and outcomes were analyzed and a review of the literature conducted. All procedures were carried out endoscopically with no intraoperative or postoperative morbidity. Plantar anhidrosis was achieved in all the patients, although two patients (20%) suffered a relapse. Unwanted side-effects occurred in the form of compensatory sweating in three patients (30%) and post-sympathectomy neuralgia in two patients (20%). None of the patients experienced sexual dysfunction. Management of plantar hyperhidrosis may be based upon a therapeutic ladder starting with conservative measures and working up to surgery depending on the severity of the disease. Minimally invasive (endoscopic) sympathectomy for the thoracic chain is well established, but minimally invasive sympathectomy for the lumbar chain is a relatively new technique. Endoscopic lumbar sympathectomy provides an effective, minimally invasive method of surgical management, but long-term data are lacking. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    Full Text Available OBJECTIVE Lumbar spinal surgeries have been performed with either spinal or general anaesthesia. In this study, we aimed to evaluate the superiority of either spinal or general anaesthesia on lumbar spine surgery. METHODS After approval of institutional ethical committee, we retrospectively analysed 270 patients (ASA I and II undergoing surgery of lumbar spine from 2009 to 2015 by one surgeon. Of these 150 patients underwent general anaesthesia with controlled ventilation, 120 patients were offered spinal anaesthesia with conscious sedation. Patient records were reviewed to obtain demographic features, type of anaesthesia, baseline heart rate, mean arterial pressure, intraoperative maximum heart rate, mean arterial pressure, duration of surgery, amount of intravenous fluids, intraoperative blood loss, incidence of perioperative complications such as bleeding, nausea, vomiting, hypotension, bradycardia, and postoperative analgesic consumption. RESULTS Patient characteristics including baseline/intraoperative mean arterial pressure and heart rate values did not differ between groups. However, the spinal anaesthesia group experienced significantly shorter durations in the operating room and had a lower incidence of nausea, vomiting. Analgesic consumptions in general anaesthesia group was significantly higher than in spinal anaesthesia group. CONCLUSION The present study revealed that spinal anaesthesia is a safe and effective alternative to general anaesthesia for patients undergoing single level or two level lumbar laminectomy, discectomy, or even instrumentation below L2 level and has the advantage of decreased nausea, antiemetic, analgesic requirements, and fewer complications. It also ensures better postoperative recovery when compared to general anaesthesia
