A total of 439 patients operated on for lumbar spinal stenosis during the period 1974-1987 was re-examinated and evaluated for working and functional capacity approximately 4 years after the decompressive surgery. The assessment of subjective disability was based on the Oswestry low-back pain questionnaire. The proportion of excellent-to-good outcomes was 62% (women 57%, men 65%). The ability to work before or after the operation and a history of no prior back surgery were variables predictive of a good outcome. Before the operation 86 patients were working, 223 patients were on sick leave, and 130 patients were retired. After the operation 52 of the employed patients and 70 of the unemployed patients returned to work. None of the retired patients returned to work. In logistic regression analysis the ability to work preoperatively, age under 50 years at the time of operation and the absence of prior back surgery predicted a postoperative ability to work. Our results suggest that more attention should be focussed on the diagnosis of spinal stenosis and on the timing of the operative intervention.
对1974年至1987年期间因腰椎管狭窄症接受手术的439例患者进行了复查，并在减压手术后约4年对其工作能力和功能状态进行了评估。主观残疾评估基于奥斯威斯腰痛问卷。优良结果的比例为62%（女性57%，男性65%）。手术前后的工作能力以及既往无背部手术史是预后良好的预测变量。术前86例患者在工作，223例患者休病假，130例患者已退休。术后，52例在职患者和70例非在职患者重返工作岗位。退休患者无人重返工作岗位。逻辑回归分析显示，术前的工作能力、手术时年龄小于50岁以及既往无背部手术史可预测术后的工作能力。我们的结果表明，应更加关注椎管狭窄的诊断和手术干预的时机。
