One hundred patients underwent lumbar nerve root decompression without fusion. All patients were registered preoperatively in a computer-coded protocol and followed at regular intervals: 4, 12, and 24 months after surgery. A number of subjective and objective variables were investigated including data on preoperative and postoperative working conditions and sick listing. Patients' opinions on pain relief were assessed using a 4-grade scale.
Surgical results and impact on sick leave and working conditions in patients who underwent surgery for lateral spinal stenosis were evaluated in a prospective, consecutive study.
Preoperatively, 81 of the patients were employed, 21 in sedentary work, 36 in moderately heavy work, and 24 in heavy work. The majority of the patients (78%) were off work (sick listed) with a mean duration of 13 months. Mean preoperative duration of sciatic pain was 2.5 years.
Working conditions were classified into one of three categories: sedentary, moderately heavy, and heavy work. Distribution of working conditions preoperatively and postoperatively was assessed in conjunction with duration of sick leave. Change of work category postoperatively was evaluated and related to preoperative working conditions.
The effect of decompression for sciatica due to lateral spinal stenosis was gratifying in most cases with excellent results in 65% and fair in 23% of the patients concerning leg pain. The majority of patients employed preoperatively (73%) returned to work after a postoperative sick leave of 5.5 months. Patients who received disability pension postoperatively had significantly inferior surgical result concerning back pain and were also sick listed significantly longer preoperatively.
Thus, lateral spinal stenosis was improved in the majority of patients (88%) who underwent surgery, and the majority of patients who were employed before surgery returned to work after.
100例患者接受了非融合性腰椎神经根减压术。所有患者术前均按照计算机编码方案进行登记，并在术后定期随访：术后4个月、12个月和24个月。研究了一些主观和客观变量，包括术前和术后工作条件及病假的数据。使用4级量表评估患者对疼痛缓解的意见。
在一项前瞻性、连续性研究中，评估接受外侧椎管狭窄手术患者的手术结果及其对病假和工作条件的影响。
术前，81例患者有工作，其中21例从事久坐工作，36例从事中等强度工作，24例从事重体力工作。大多数患者（78%）休假（病假），平均时长为13个月。术前坐骨神经痛的平均时长为2.5年。
工作条件分为三类：久坐、中等强度和重体力工作。结合病假时长评估术前和术后工作条件的分布情况。评估术后工作类别变化，并将其与术前工作条件相关联。
大多数情况下，外侧椎管狭窄导致的坐骨神经痛减压效果令人满意，65%的患者腿部疼痛结果优秀，23%的患者结果良好。大多数术前有工作的患者（73%）在术后病假5.5个月后重返工作岗位。术后领取残疾抚恤金的患者背痛手术结果明显较差，术前病假时间也明显更长。
因此，大多数接受手术的患者（88%）外侧椎管狭窄情况得到改善，大多数术前有工作的患者术后重返工作岗位。
