STUDY DESIGN A case report of nontraumatic acute complete paraplegia resulting from cervical disc herniation. OBJECTIVES To describe a rare case of nontraumatic paraplegia resulting from enlargement of a herniated disc in the cervical spine and to outline appropriate management of a patient with severe spinal cord compression secondary to disc herniation with developmental spinal canal stenos...

Intradural lumbar disc herniation is a rare pathological entity. The pathogenesis of intradural lumbar disc herniation is not known clearly. Intradural disc herniations usually occurred at the L4-L5 levels but have also been reported at other levels. However, intradural disc herniation at L5-S1 is quite rare. There are approximately nine reports in the English literature of intraradicular disc ...

The most common complication after lumbar discectomy is reherniation. As the first step in reducing the rate of recurrence, many studies have been conducted to find out the factors that may increase the reherniation risk. Some reported factors are age, sex, the type of lumbar disc herniation, the amount of fragments removed, smoking, alcohol consumption and the length of restricted activities. ...

STUDY DESIGN The expression of cyclooxygenase-2 was studied immunohistologically in specimens from lumbar disc herniation. The cultured disc cells also were examined to evaluate the significance of cyclooxygenase-2, which might be involved in the pathogenesis of lumbar disc herniation. OBJECTIVE To investigate whether cyclooxygenase-2 might be involved in the pathogenesis of lumbar disc herni...

Patients suffering from a lumbar herniated disc will typically present with signs and symptoms consistent with radiculopathy. They may also have low-back pain, however, and the source of this pain is less certain, as it may be from the degenerative process that led to the herniation. The surgical alternative of choice remains a lumbar discectomy, but fusions have been performed for both primary...

PURPOSE Small spinal canal dimensions play a role in symptomatic adult disc herniation, but its role in adolescent disc herniation has not been investigated with MRI. The goal of this study was to examine retrospectively if there is a correlation with dimensions of osseous spinal canal and need of discectomy in an adolescent population suffering from disc herniation. METHODS A retrospective r...

HAS THERE BEEN PROGRESS IN THE PHYSIOPATHOLOGY OF DISC HERNIATION ASSOCIATED RADICULOPATHY? Since 1934, when a link was demonstrated between disc herniation and sciatica, it has been accepted that compression of the nerve root by disc herniation explained the sciatica. Surgical treatment therefore became standard when medical treatment failed. It now seems that ‘‘chemical’’ factors have a centr...

SUMMARY OF BACKGROUND DATA The association between the facet tropism and the development of lumbar disc herniation has been studied; however the results remain controversial. OBJECTIVE To determine the association between the facet tropism and the development of lumbar disc herniation. STUDY DESIGN A cross-sectional study. MATERIAL AND METHOD MRI of 34 patients with lumbar disc herniation...
