OBJECTIVES To determine whether repetitive tibial nerve stimulation (RTNS) affects neurogenic claudication and F-wave conduction in lumbar spinal stenosis. DESIGN An intervention study: before/after trial. SUBJECTS Data for 12 central lumbar spinal stenosis patients were compared with 13 age- and sex-matched healthy volunteers. METHODS A conditioning RTNS at the ankle, 0.3-ms duration squ...

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...

This paper describes a patient who presented at our hospital with neurologic symptoms due to congenital cervical spinal stenosis at the atlas level. Congenital atlantal stenosis is usually due to hypoplasia of the posterior arch of the atlas. It is a rare cause of spinal stenosis, and only 12 symptomatic patients with isolated atlantal stenosis have been reported. Current treatment is surgical ...

STUDY DESIGN Case-control study. OBJECTIVE The aim of this study was to define clinically relevant relative and critical (absolute) magnetic resonance imaging values of lumbar spinal stenosis in a cohort of 100 surgical cases and 100 asymptomatic controls. SUMMARY OF BACKGROUND DATA Developmental spinal stenosis is a precipitating factor in patients presenting with lumbar canal stenosis. Ye...

PURPOSE To evaluate a slow-flow MR sequence in normal CSF flow and in CSF flow disturbance in cases of spinal stenosis. METHOD The method was tested for flow sensitivity and applied to 67 sites of spinal canal compromise. RESULTS Phantom studies show that flow can be depicted at a velocity of 0.5-1 mm/sec. On clinical images, stagnant CSF is black, flowing CSF is bright. Typically, in high-...

Spinal stenosis and degenerative spondylolisthesis share many symptoms and the same treatment, but their causes remain unclear. Bone mineral density has been suggested to play a role. The aim of this study was to investigate differences in spinal bone density between spinal stenosis and degenerative spondylolisthesis patients. 81 patients older than 60 years, who underwent DXA-scanning of their...

background & aim: lumbar spinal stenosis (lss) is a common condition. this congenital or acquired stenosis has multiple etiologies. the goal of this study was to describe intraoperative pathoanatomic findings of lumbar spinal stenosis observed within a black african population. methods & materials/patients: it was a retrospective and descriptive study performed at departmental teaching hospital...

Generally, bilateral pedicle screw fixation after Minimal Invasive (MIS) TLIF is accepted as a standard procedure for treating symptomatic spinal pathologies, such as degenerative spinal stenosis, spondylolisthesis, recurrent disc herniation, postlaminectomy instability, and deformity (10). Some authors have recently demonstrated that unilateral pedicle screw fixation is as effective for spinal...

CONTEXT Lumbar central spinal stenosis is common and often results in chronic persistent pain and disability, which can lead to multiple interventions. After the failure of conservative treatment, either surgical or nonsurgical modalities such as epidural injections are contemplated in the management of lumbar spinal stenosis. EVIDENCE ACQUISITION Recent randomized trials, systematic reviews ...
