STUDY DESIGN A questionnaire survey. OBJECTIVE The aim of this study was to determine the effect of patient age, dynamic instability, and/or low back pain on the treatment of patients with a degenerative spondylolisthesis, and if the operative approach is affected by surgeon specialty, location, or practice model. SUMMARY OF BACKGROUND DATA The classic treatment for patients with symptomati...

STUDY DESIGN A subanalysis study. OBJECTIVE The purpose of this study was to determine the impact of multilevel lumbar stenosis with or without degenerative spondylolisthesis compared to single level disease on patients' baseline symptoms and clinical outcomes over time. SUMMARY OF BACKGROUND DATA Previous studies have demonstrated better clinical outcomes with surgery than nonoperative tre...

OBJECTIVE To investigate the role of lumbosacral radiculography using 3-dimentional (3D) magnetic resonance (MR) rendering for diagnostic information of symptomatic extraforaminal stenosis in lumbosacral transitional vertebra. MATERIALS AND METHODS The study population consisted of 18 patients with symptomatic (n = 10) and asymptomatic extraforaminal stenosis (n = 8) in lumbosacral transition...

CASE SUMMARY Lumbosacral agenesis is a rare congenital condition reported in children. We report a 17-week-old female domestic shorthair cat with lumbosacral agenesis on whole-body radiographs. The cat was euthanized shortly thereafter presentation. A necropsy was not permitted. RELEVANCE AND NOVEL INFORMATION This is the first reported feline case of lumbosacral agenesis.

Patients presumed to have lower limb symptoms localizing to the lumbar or lumbosacral plexus require rigorous electrophysiological evaluation. Entities that cause lumbosacral plexopathies may be patchy, asymmetrical and more diffuse than initially suspected. As a result, bilateral nerve conduction studies and needle examination outside those routinely tested and clinically affected may be neede...

Lumbosacral perineural cysts are formed by the arachnoid membrane of the nerve root at the lumbosacral level. Most of these cysts are asymptomatic and are found incidentally during computed tomography (CT) or magnetic resonance imaging (MRI) for other causes of chronic lower back pain. This type of cyst requires a differential diagnosis to distinguish it from other causes of radiating pain and ...
