物体。本研究的目的是探讨不同的变量在症状持续时间上是否可以用ChAT来预测腰椎间盘摘除术后的预后。在一项对132名连续接受腰椎间盘突出症手术的患者进行的前瞻性研究中，作者评估了术后1年内症状持续时间的不同变量对预后的价值。为期一年的跟踪调查由一名独立观察员进行。使用临床总评分(COS)对结果进行评估，最近对其可靠性和有效性进行了评估。对于预后的预测因素，在多因素分析中，只有腿痛和病假的持续时间有统计学意义。单因素分析结果显示，与小腿疼痛持续时间较长(8个月)的患者相比，术前小腿疼痛少于4个月和4至8个月的患者，术后1年随访的COS显著降低。108例患者在术后1年内重返工作岗位。手术前请病假超过28周的患者不再返回工作岗位的风险较高。对这些结果的分析表明，腰椎间盘突出症患者持续8个月以上的腿痛与不良的术后结果以及无法重返工作岗位的风险有关。
Object. The aim of this study was to investigate different variables in the duration of symptoms chat can be used to predict outcome after lumbar microdiscectomy.Methods. In a prospective study of 132 consecutive patients who underwent surgery for lumbar disc herniation, the authors evaluated the prognostic value of different variables in the duration of symptoms for the 1-year period after surgery. The 1-year follow-up investigation was conducted by an independent observer. Assessment of outcome was performed using a clinical overall score (COS), which was recently assessed for its reliability and validity. As for factors predictive of outcome, only duration of leg pain and sick leave reached statistical significance in the multivariate analysis. Results of the univariate analysis demonstrated that in patients experiencing preoperative leg pain fewer than 4 months and between 4 and 8 months, a significantly lower COS at the I year follow up was demonstrated compared with those in whom the duration of leg pain was longer (> 8 months). One hundred eight patients returned to work within the Ist year after surgery. Patients who took a sick leave of more than 28 weeks before the operation were at higher risk of not returning to work.Conclusions. Analysis of these results indicates that leg pain lasting more than 8 months correlates with an unfavorable postoperative outcome in patients with lumbar disc herniation, as well as a hi,oh risk of not returning to work.
