STUDY DESIGN A randomized controlled trial. OBJECTIVES To assess the effectiveness of decompressive surgery as compared with nonoperative measures in the treatment of patients with lumbar spinal stenosis. SUMMARY OF BACKGROUND DATA No previous randomized trial has assessed the effectiveness of surgery in comparison with conservative treatment for spinal(More)
The objective of this observational prospective study was to investigate the effect of depression on short-term outcome after lumbar spinal stenosis (LSS) surgery. Surgery was performed on 99 patients with clinically and radiologically defined LSS, representing ordinary LSS patients treated at the secondary care level. They completed questionnaires before(More)
STUDY DESIGN Systematic review. OBJECTIVE To define preoperative factors predicting clinical outcome after lumbar spinal stenosis (LSS) surgery. SUMMARY OF BACKGROUND DATA LSS is the most common reason requiring lumbar spine surgery in adults older than 65 years. There are no published systematic reviews on this topic. METHODS A literature search was(More)
STUDY DESIGN A retrospective, follow-up study. OBJECTIVES To investigate the overall outcome of surgery for lumbar spinal stenosis and to investigate the preoperative factors affecting outcome. SUMMARY OF BACKGROUND DATA The success rates of surgical intervention for lumbar spinal stenosis vary, and few preoperative factors have been found to be(More)
The classic method of open bone grafting in the treatment of un-united tibial fractures has been associated with some complications. A novel, minimally invasive, percutaneous technique of bone grafting is described. Forty-one consecutive patients with delayed union or non-union of a tibial fracture was treated with percutaneous bone grafting from 1993 to(More)
STUDY DESIGN A cross-sectional retrospective study to observe the correlation between postoperation findings shown on magnetic resonance imaging and clinical observations of 56 patients 10 years after laminectomy for lumbar spinal stenosis. OBJECTIVE To evaluate the relation between postoperation findings on magnetic resonance imaging and surgical outcome(More)
BACKGROUND AND AIMS Lumbar spinal stenosis (LSS) is the most frequent indication for back surgery in adults aged over 65 years, but about one-third of operated patients have less than good/excellent results from the operation. Awareness of outcome predictors and their predictive values may help clinicians in their assessment of the prognosis of patients(More)
PURPOSE To investigate the prevalence of depression and associated factors in patients (n = 100) with lumbar spinal stenosis selected for surgical treatment. METHOD Depression was assessed with the 21-item Beck Depression Inventory. Psychological well-being was assessed with Life Satisfaction Scale, Toronto Alexithymia Scale and Sense of Coherence Scale.(More)
We randomised a total of 94 patients with long-standing moderate lumbar spinal stenosis (LSS) into a surgical group and a non-operative group, with 50 and 44 patients, respectively. The operative treatment comprised undercutting laminectomy of stenotic segments, augmented with transpedicular-instrumented fusion in suspected lumbar instability. The primary(More)
UNLABELLED INTRODUCTION AND MATERIALS: We examined lumbar transpedicular instrumented posterolateral fusion patients operated on between 1992 and 1997 presenting: degenerative spondylolisthesis with spinal stenosis; adult isthmic spondylolisthesis; failed back syndrome after one to five discectomies; and failed back syndrome after one to three laminectomy(More)
