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...

Degenerative disease of the lumbar spine refers to a syndrome in which an intervertebral disc with adjacent spine structures is compromised, this can be due to aging process associated with pathology. Thirty five percent of asymptomatic individuals may have degenerative spine findings, including: disc degeneration, modic changes, disc bulges, facet joint arthropathy and spinal stenosis. Plain r...

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...

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 Beside symptoms and clinical signs radiological findings are crucial in the diagnosis of lumbar spinal stenosis (LSS). We investigate which quantitative radiological signs are described in the literature and which radiological criteria are used to establish inclusion criteria in clinical studies evaluating different treatments in patients with lumbar spinal stenosis. METHODS A lite...

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

BACKGROUND The symptom severity of back pain/leg pain is not correlated with the severity of degenerative changes and canal stenosis in lumbar stenosis. Considering the individual pain sensitivity might play an important role in pain perception, this discordance between the radiologic findings and clinical symptoms in degenerative lumbar stenosis might originate from the individual difference o...

OBJECTIVES Pedicle-lengthening osteotomy is a novel surgery for lumbar spinal stenosis (LSS), which achieves substantial enlargement of the spinal canal by expansion of the bilateral pedicle osteotomy sites. Few studies have evaluated the impact of this new surgery on spinal canal volume (SCV) and neural foramen dimension (NFD) in three different types of LSS patients. METHODS CT scans were p...
