Introduction Lumbar spinal stenosis is narrowing of the central spinal canal, lateral recess or the neural foramen. After initial recognition of spinal stenosis in 1802, a gradual understanding evolved over the next 150 years.1-4 Harris and Macnab described the importance of disc degeneration in the pathogenesis of stenosis.5 Macnab highlighted the lateral recess beneath the posterior facet joi...

abstract p u rpose: this study aimed to correlation between the grading stenosis and the start back screening tool (sbst) in patients diagnosed with lumbar central canal stenosis (lccs). methods: in a prospective clinical study, a total of 269 patients with lccs were asked to respond to the questionnaire at their first visits. grading of lccs on mri was determined and also the severities of the...

We carried out an MRI study of the lumbar spine in 15 patients with achondroplasia to evaluate the degree of stenosis of the canal. They were divided into asymptomatic and symptomatic groups. We measured the sagittal canal diameter, the sagittal cord diameter, the interpedicular distance at the mid-pedicle level and the cross-sectional area of the canal and spinal cord at mid-body and mid-disc ...

Developmental stenosis without any significant spondylotic changes frequently occurs at C3 vertebra or below, and typically extends to C6-C7. However, high cervical focal canal stenosis is unusual. A case of cervical canal segmental stenosis at C2-3 level in addition to a developmental stenosis of the lumbar region, in a 45 year old male, has been presented in this article. The dynamics of the ...

Treatment of cervical stenosis involves opening or widening the cervical canal. The condition may improve on its own following the vaginal delivery of a baby. Cervical canal widening can be temporarily achieved by the insertion of dilators into the cervix. If the stenosis is caused by scar tissue, a laser treatment can be used to vaporize the scarring. Finally, the surgical enlargement of the c...

There have been few clinical studies in the area of cervical spine that focused on surgery for treating degenerative lumbar disease in patients with rheumatoid arthritis (RA). High rates of wound complications and instrumentation failure have been reported more for RA than for non-RA patients, although clinical outcomes are similar between the two groups. Lumbar canal stenosis in RA is caused n...

BACKGROUND Lumbar spinal stenosis (LSS) is the common term used to describe patients with symptoms related to the anatomical reduction of the lumbar spinal canal size. However, some subjects may have a markedly narrowed canal without any symptoms. This raises the question of what is the actual role of central canal stenosis in symptomatic patients. The purpose of this study was to compare radio...

We herewith report 2 patients with congenital aural stenosis who developed cholesteatoma related to the external ear canal (EEC) stenosis. One of the cases, had previously undergone craniotomy for intracranial complication of the disease, and also had postauricular fistula, whereas in the second patient it was silent and confined within the relatively enlarged stenotic ear canal in front of a r...
