摘要 目的探讨颈后路单开门椎管扩大成形术治疗多节段脊髓型颈椎病的疗效及影响因素。方法对76例多节段脊髓型颈椎病患者行后路单开门椎管扩大成形术,术前术后进行JOA评分及Hirabayashi改善率评分。结果 76例均获随访,时间6~36(24.6±10.2)个月。JOA评分:术前为9.5分±2.41分,术后为12.92分±1.69分(P<0.05)。术后患者神经功能有不同程度的改善,末次随访改善率为54.60%±15.52%。结论颈后路单开门椎管扩大成形术能有效地解除脊髓的压迫,改善神经功能,疗效肯定。年龄、病程、术前JOA评分对脊髓功能改善率影响显著,年龄越大、病程越长、术前JOA评分越低的患者,术后脊髓功能改善越差。 Objective To evaluate the clinical outcome and prognostic factors of open-door laminoplasty(ELAP) for multi-segmental cervical spondylotic myelopathy (CSM). Methods A retrospective analysis of 76 patients with ELAP following CSM treated was performed. Japanese Orthopaedic Association (JOA) scores arid Hirabayashi scores we~ recorded preoperatively and postoperatively. Results The preoperative and postoperative JOA score was 9.5 ±2.41 and 12.92 ± 1.69 respectively with the time of follow-up 6 -36 (24. 6 ± 10. 2) months. All patients had been, in some extent, improved in neurologlcal status and the recovery ratio was 12.92 ± 1.69 (P 〈 0. 05 ). The improve- ment rate of neural function was 54. 60%±15.52% in the last follow-up. Conclusions ELAP can be applied to multi-segmental CSM with manifest effect on decompression and neurological status. In addition, other factors, such as age, pathogenesis and preoperative JOA scores, are significant factor in recovery ratio.
