Spinal stenosis is a term that means narrowing of the spinal canal or the nerve root foramina. It is thus divided into central or lateral stenosis. Central stenosis produces compression of the thecal sac: soft tissue (ligamentum flavum and disc) may contribute as much as 40% to this compression. It is more common in males because their spinal canal is smaller at the L3-L5 level. Lateral stenosi...

OBJECTIVES This study was undertaken to determine the results of repair of partial atrioventricular (AV) canal in patients > or = 40 years old. BACKGROUND Although postoperative outcomes in younger patients have been well documented, the fate of older patients with repaired partial AV canal is less clear. METHODS From 1958 to 1990, 31 patients 40 to 71 years old (mean age 51) had repair of ...

Background: Obesity is likewise becoming more prevalent in patients with lumbar spinal canal stenosis, but few studies have examined relationships between obesity levels and surgical outcomes for this condition. The purpose of the present study is to determine the influence of body-mass index (BMI) on outcomes of surgery for lumbar spinal canal

The hypothesis that somatotype and cervical spine developmental canal stenosis may be associated has been investigated by anthropometry and measurement of lateral projection cervical spine radiographs. A significant association of canal size with somatotype has been found such that those with developmentally narrow canals are more likely to have relatively shorter long-bones, particularly in th...

The shallow lateral recesses of the trefoil shape of the lumbar spinal canal have been implicated in the production of the spinal stenosis syndrome. In the present study, 485 skeletons of South African Blacks and Whites were examined in order to establish the incidence and possible genesis of the trefoil configuration. The overall incidence was 14 per cent, with little variation between the sex...

Lumbar spine stenosis most commonly affects the middle-aged and elderly population. Entrapment of the cauda equina roots by hypertrophy of the osseous and soft tissue structures surrounding the lumbar spinal canal is often associated with incapacitating pain in the back and lower extremities, difficulty ambulating, leg paresthesias and weakness and, in severe cases, bowel or bladder disturbance...

Internal fixation of traumatic spinal injuries has been associated with spinal canal stenosis, spinal cord compression, and nerve root impingement. We present a case of spinal cord/cauda equina compression due to migration of intact, anchored thoracolumbar Luque rods into the spinal canal through a laminectomy defect, leading to neurologic complications 10 years after the original operation.

Bardet-Biedl syndrome (BBS) is a rare, autosomal-recessive, debilitating genetic disorder, which can present with multitudinous systemic clinical features including rod-cone dystrophy, polydactyly, Frohlich-like central obesity, mental retardation, hypogonadism, and renal anomalies. Diverse neuromuscular manifestations in patients afflicted by this heterogeneous disorder include ataxia, cervica...

This study was to evaluate the morphological features of degenerative spinal stenosis and adequacy of lateral canal stenosis decompression via unilateral and bilateral laminectomy. Measurements of facet joint angulation (FJA), mid facet point (MFP), mid facet point distance (MFPD), the narrowest point of the lateral spinal canal (NPLC) and the narrowest point of the lateral spinal canal distanc...

Lumbar spinal stenosis refers to a diversity of conditions that decrease the total area of the spinal canal, lateral recesses, or neural foramina. Lumbar stenosis is a common disorder that may be present in isolation, with or without associated disk bulge or herniation, or can be associated with degenerative spondylolisthesis or scoliosis. Symptomatic lumbar spinal stenosis is characterized by ...
