Vasculitic polyradiculopathy in systemic lupus erythematosus. (1/129)

A 22 year old woman with recently diagnosed systemic lupus erythematosus presented with subacute progressive areflexic paraparesis, electrophysiologically identified as a pure axonal polyradiculopathy. Sural nerve biopsy disclosed necrotising vasculitis. A striking radiological feature was marked enhancement of the cauda equina with gadolinium.  (+info)

Neurological complications of spinal tuberculosis in children. (2/129)

Neurological complications of thoracic and lumbar spinal tuberculosis were studied in 32 patients under the age of 16 years. The majority had lesions involving three or more vertebral bodies. Paraplegia occurred in 8 patients and was always associated with bladder and bowel dysfunction. Lesions located at T4/5 were most commonly accompanied by paraplegia. Deterioration of the neurological status was related to the degree of spinal stenosis, whereas the degree of kyphosis was of less importance. Radiculopathy is rare in children with Pott's disease.  (+info)

Extramedullary astrocytoma of conus region : a short report. (3/129)

A 55 year old man presented with features of cauda equina syndrome. Magnetic resonance imaging (MRI) showed a well demarcated intradural extramedullary tumour at L2 vertebra. At surgery it was found to be well encapsulated and had no attachment to spinal cord or root. Histopathology including immunohistochemistry confirmed it to be a low grade astrocytoma.  (+info)

The association of the involvement of financial compensation with the outcome of cervicobrachial pain that is treated conservatively. (4/129)

OBJECTIVES: To examine the influence of the involvement of financial compensation on the results of physiotherapeutic McKenzie treatment on cervicobrachial pain. METHODS: A prospective study was carried out with a cohort of 60 patients referred to two spine clinics after they had experienced at least 5 weeks of neck pain radiating to the arm. Follow-up was performed 1 yr later using a validated questionnaire to measure the outcomes of neck and arm pain, disability, the use of analgesics and the perceived effect of the treatment as reported by the patient. RESULTS: At follow-up, there was no improvement in the group of patients for whom financial compensation was involved, whereas the group for whom compensation was involved showed highly significant improvement. CONCLUSIONS: Despite uniform selection criteria and similarity of complaints and treatment protocols, the involvement of financial compensation seemed to be associated with an adverse effect on treatment results for patients with cervicobrachial pain who were treated conservatively.  (+info)

Posterior epidural migration of a lumbar disc fragment causing cauda equina syndrome: case report and review of the relevant literature. (5/129)

Posterior epidural migration (PEM) of free disc fragments is rare, and reported PEM patients usually presented with radicular signs. An uncommon case involving a patient with cauda equina syndrome due to PEM of a lumbar disc fragment is reported with a review of the literature. The patient described in this report presented with an acute cauda equina syndrome resulting from disc fragment migration at the L3-L4 level that occurred after traction therapy for his lower back pain. The radiological characteristics of the disc fragment were the posterior epidural location and the ring enhancement. A fenestration was performed and histologically confirmed sequestered disc material was removed. An early postoperative examination revealed that motor, sensory, urological, and sexual functions had been recovered. At late follow-up, the patient was doing well after 18 months. Sequestered disc fragments may occasionally migrate to the posterior epidural space of the dural sac. Definite diagnosis of posteriorly located disc fragments is difficult because the radiological images of disc fragments may mimic those of other more common posterior epidural lesions.  (+info)

Complications of lumbar drainage after thoracoabdominal aortic aneurysm repair. (6/129)

OBJECTIVES: Paraplegia remains a frequent complication of thoracoabdominal aortic aneurysm (TAAA) repair. Many adjunct therapies have been developed to address this complication. Lumbar drainage is frequently used in an attempt to decrease intrathecal pressure and improve intramedullary perfusion pressure. The effectiveness of this therapy is unclear, and the complications of lumbar drainage used for this indication are unknown. We present a case of intraspinal hematoma with significant neurologic deficit after TAAA repair and review the associated complications of lumbar drains placed for TAAA. METHODS: The charts of all patients undergoing operations for TAAA repair were reviewed. Patients who underwent perioperative placement of a lumbar drain were included regardless of aneurysm type or etiology. Demographics, Crawford grade, and perioperative parameters and complications were reviewed. RESULTS: Sixty-five patients underwent TAAA repair with 62 (95%) receiving a preoperative lumbar drain. There were two (3.2%) intraspinal hemorrhagic complications, including one patient with a poor neurologic outcome. No infections or other complications directly related to drainage were identified. Multivariate logistic regression analysis failed to demonstrate a significant association between lumbar drain complications and perioperative and intraoperative parameters such as blood loss or hypotension, level of drain placement, and Crawford grade. CONCLUSIONS: Lumbar drainage is a frequent adjunct to TAAA repair. However, placement of the drain itself can be associated with significant complications whose aggravating factors may be unidentifiable. Complications resulting from lumbar drainage should be considered in any patient who has postoperative lower extremity neurologic deficits.  (+info)

Clinical outcomes of revision lumbar spinal surgery: 124 patients with a minimum of two years of follow-up. (7/129)

BACKGROUND: Pertinent literature on revision lumbar spinal surgery has revealed a wide variation in success rates, ranging from 12% to 82%. In addition, a solid consensus has not yet been reached on its positive factors. We retrospectively reviewed 124 consecutive patients who underwent revision lumbar spinal surgery and investigated the factors that affected the outcomes of their surgery. METHODS: Revision lumbar spinal surgery was performed in 124 patients from January 1992 to December 1996, with an average follow-up of 37.6 months (range, 24-89 months). The various factors analyzed included age, gender, previous diagnosis, number of previous operations, period of pain-free interval, neurologic deficit, operative procedure, and fusion status. This analysis revealed the effect of each factor on the overall results. Radiographs were obtained, and patients were assessed during the final follow-up or by questionnaire. RESULTS: The success rate of revision lumbar spine surgery in this study was 83.9%. Successful outcomes were significantly associated with the spinal procedure with fusion and with union of the spinal fusion. Patients with defined mechanical instability had better results than did those with stenosis only. In addition, the complication rate for repeated lumbar spinal surgery was 9.6% and major complications attributed to poor results. CONCLUSION: This study reveals a high success rate of revision spinal surgery. We recommend performing spinal fusion, and achievement of solid fusion in repeated low back surgery is invaluable for patients with spinal instability. Targeting the specific pathology of failed back surgery syndrome is crucial in attaining satisfactory results with revision lumbar spinal surgery.  (+info)

Cauda equina syndrome caused by idiopathic sacral epidural lipomatosis. (8/129)

The patient, who was a non-obese woman with no predisposing conditions of lipomatosis, slowly developed cauda equina syndrome. Spinal magnetic resonance imaging (MRI) presented mass lesion of high intensity on T1-weighted image (WI) and an intermediate signal intensity in T2 WI in the epidural space of S1 to coccyges. It has been reported that most idiopathic epidural lipomatosis (IEDL) is observed in obese men, and all cases have involved the thoracic or lumbar region. This is the first report of a patient with cauda equina syndrome caused by idiopathic sacral epidural lipomatosis (EDL).  (+info)
