BACKGROUND The lumbar spine includes 5 lumbar vertebral bodies, L1, L2, L3, L4, and L5. At each level, there is a disc space defined by the two bones (vertebral bodies) in the back; for example, there is a disc space at the L5-S1 level etc. The normal front to back (anterior to posterior or AP diameter) measurement of the spinal canal is typically 18-20 mm, but some patients have narrowing call...

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 ...

Stenosis of spinal canal becomes important only when it resul...

Three cases of postoperative lumbar spinal canal stenosis due to anterior spinal fusion were reported. In these cases stenosis occurred at the adjacent intervertebral disc level of the fused segment a considerable time after anterior spinal fusion performed for spondvlolisthesis. At the stenotic level of the lumbar spinal canal, hypertrophy of the lamina, body spur formation in the articular pr...

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...

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 ...

STUDY DESIGN Cross-sectional retrospective study designed to assess interobserver agreement. PURPOSE To investigate if interobserver agreement using magnetic resonance imaging (MRI) in the evaluation of lumbar spinal canal stenosis and root compression can be improved upon combination with magnetic resonance myelography (MRM). OVERVIEW OF LITERATURE The interpretation of lumbar spinal MRI, ...

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

case presentation an 85 years old patient presented because of intractable right leg pain with minimal activities. she was diagnosed with significant right foraminal stenosis and she failed conservative non-invasive therapies. conclusions percutaneous lumbar hydro decompression can be a promising method for the treatment of the patients with lumbar spinal stenosis and neurogenic claudication se...

BACKGROUND Lumbar spinal stenosis is a pathological condition of the spinal channel with its concentric narrowing with presence of specific clinical syndrome. Absence of the clear unified radiological signs is the one of the basic problems of the lumbar spinal stenosis. PURPOSE The authors seek to create method of assessment of the spinal canal narrowing degree, based on anatomical aspects of...
