BACKGROUND Although some investigators believe that the rate of postoperative instability is low after lumbar spinal stenosis surgery, the majority believe that postoperative instability usually develops. Decompression alone and decompression with fusion have been widely used for years in the surgical treatment of lumbar spinal stenosis. Nevertheless, in recent years several biomechanical studi...

OBJECTIVE To analyze the effect of decompression alone and combined decompression, fusion and internal fixation procedure for degenerative lumbar stenosis in elderly patients. METHODS We reviewed 168 lumbar stenosis patients treated using decompression alone or with combined procedures in the department of orthopaedics of Tianjin 4(th) Centre Hospital from October 2010 to January 2014. The cl...

conclusions both dexmedetomidine and esmolol can be used as agents to control hypotension in patients undergoing lumbar spine decompression and fixation surgery; the dexmedetomidine group, however, was associated with better intraoperative hemodynamic stability and reduced intraoperative analgesic and volatile anaesthetic requirement. results the study results showed that dexmedetomidine had lo...

Paraspinal muscles are commonly affected during spine surgery. The purpose of this study was to assess the potential factors that contribute to paraspinal muscle atrophy (PMA) after lumbar spine surgery. A comprehensive review of the available English literature, including relevant abstracts and references of articles selected for review, was conducted to identify studies that reported PMA afte...

Instrumented lumbar fusion can provide immediate stability and assist in satisfactory arthrodesis in patients who have pain or instability of the lumbar spine. Lumbar adjunctive fusion with decompression is often a good procedure for surgical management of degenerative spondylolisthesis (DS). Among various lumbar fusion techniques, lumbar interbody fusion (LIF) has an advantage in that it maint...

STUDY DESIGN Retrospective. PURPOSE To report the outcomes of patients with lumbar spinal stenosis treated with percutaneous endoscopic decompression, focusing on the results of clinical evaluations. OVERVIEW OF LITERATURE There are no studies about two portal percutaneous endoscopic decompression in the treatment of lumbar spinal stenosis. METHODS Medical and surgical complications were ...

STUDY DESIGN Retrospective analysis of a prospective, multicenter cohort study. OBJECTIVE To estimate the added effect of surgical fusion as compared to decompression surgery alone in symptomatic lumbar spinal stenosis patients with spondylolisthesis. SUMMARY OF BACKGROUND DATA The optimal surgical management of lumbar spinal stenosis patients with spondylolisthesis remains controversial. ...

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...

introduction traumatic lumbar spondylolisthesis is rare disease and in the literature, different surgical approaches, including anterior, posterior, or combined approaches (posterior and anterior) are used to treat the lesion. case presentation we treated a case of traumatic lumbosacral spondylolisthesis using posterior approach and the patient showed a satisfactory outcome. at the final follow...

Traumatic spondylolisthesis of the lumbar spine is uncommon and can result in canal narrowing and spinal cord injury. Early decompression promotes recovery of neurological function. We report 3 such cases: one in the lumbosacral joint and 2 in the lumbar spine. The former patient had an open fracture-dislocation and underwent (delayed) posterior decompression and instrumentation without interbo...
