The authors have made a retrospective study of a cohort of patients who underwent surgery for spinal stenosis. A total of 85 patients were surgically treated for spinal stenosis between 1993 and 1997, and 79 patients were available for re-evaluation. The average time of follow-up was 79 months. Twenty patients with monosegmental stenosis underwent fenestration and undercutting, 16 patients had ...

The aim of the study was to compare outcome of surgery in patients with lumbar canal stenosis (LCS) based on magnetic resonance imaging (MRI) morphology. This was a prospective study of 96 consecutive patients who underwent surgery at 143 levels of LCS (from L3-L4 to L5-S1). Using patterns on T2 axial MRI, the type of stenosis was determined for each patient. The Swiss Spinal Stenosis Score (SS...

Background & Aim: Surgical management of lumbar spinal stenosis (LSS) is a common practice. The aim of this study to was to report morbidity and mortality observed during surgical treatment of LSS and the outcome of these patients after management over an 8-year study period. Methods & Materials/Patients: It was a retrospective, descriptive and transversal study performed at Departmental Te...

Background. Several different techniques exist to address the pain and disability caused by isolated nerve root impingement. Failure to adequately decompress the lumbar foramen may lead to failed back surgery syndrome. However, aggressive treatment often causes spinal instability or may require fusion for satisfactory results. We describe a novel technique for decompression of the lumbar nerve ...

OBJECTIVE We compared the results of two surgical techniques by retrospective study of 60 elderly patients (65 years or older) who underwent either decompression alone or fusion for the treatment of two-level or more lumbar spinal stenosis. METHODS During the period of 2003 and 2008, two-level or more decompression alone or fusion was performed for lumbar spinal stenosis by three surgeons at ...

Spinal stenosis was described, for the first time, as one of the causes of neural compression by Bailey and Casamajor (1) in 1911. Later, in 1954, it was described by Verbiest (2) as the typical clinical presentation of bilateral neurogenic claudication, which is provoked by prolonged standing and lower back extension and relieved by sitting and flexing the lumbar spine. Degenerative lumbar spi...

background & aim: lumbosacral pain is extremely common as age increases. spinal instrumentation is sometimes recommended for lumbar canal stenosis and disk herniation surgery. this study aimed at studying the frequency of instrumentation in patients referring to our center. methods & materials/patients: this retrospective cross-sectional study included 1200 patients with low back and/or radicul...

Planning of surgical treatment requires determination of whether osteoarthritis of the spine with lumbar pain should be treated as spinal canal stenosis with or without deformity or as lumbar degenerative scoliosis and clarification of whether treatment should be provided for both. When sagittal spinal alignment is not appropriate, symptoms of adult spinal deformity may be observed. To correct ...

Degeneration of the intervertebral disc results in initial relative instability, hypermobility, and hypertrophy of the facet joints, particularly at the superior articular process. This finally leads to a reduction of the spinal canal dimensions and compression of the neural elements, which can result in neurogenic intermittent claudication caused by venous congestion and arterial hypertension ...
