显微镜下颈前路椎间隙减压治疗老年脊髓型颈椎病

Anterior cervical intervertebral space decompression under microscope for cervical spondylotic myelopathy in elderly patients

目的：观察显微镜下颈前路椎间隙减压治疗老年脊髓型颈椎病的疗效。方法：自2009年6月至2012年3月在显微镜下经颈前路行椎间隙减压治疗老年脊髓型颈椎病患者43例，其中男26例，女17例；年龄60-72岁，平均（64．9±3．7）岁。术前JOA评分7～12分，平均（9．5±1．8）分。采用JOA评分对手术前后的神经功能状况进行评定。结果：术后所有患者获得随访，时间10—18个月，平均（14．7±1．6）个月。术后JOA评分10-16分，平均（13．81±1．44）分，较术前明显改善（P〈0．01）。根据功能改善率，优9例，良26例，中7例，差1例。结论：显微镜下颈前路间隙减压对老年脊髓型颈椎病有良好的疗效。

Objective ：To investigate the clinical effects of anterior cervical intervertebral space decompression under mi- croscope in treating cervical spondylotic myelopathy in elderly patients. Methods：From June 2009 to March 2012,43 patients with cervical spondylotic myelopathy were treated with anterior cervical intervertebral space decompression and intervertebral fusion under microscope. There were 26 males and 17 females,aged from 60 to 72 years old with an average of （64.9±3.7） years. Japanese Orthopaedic Association System （JOA） score was from 7 to 12 points with an average of （9.5±1.8） points before operation. The function of nerves was assessed before and after operation according to JOA. Results： All patients were followed up from 10 to18 months with an average of （14.7±1.6） months. Postoperative JOA score was （13.81±1.44） points （ranged, 10 to 16） ,had significantly higher than preoperative （P〈0.01）. According to the rate of the improved JOA score ,9 cases got excellent results, 26 good, 7 fair, 1 poor. Conclusion： Anterior cervical intervertebra] space decompression under microscope for cervical spondylotic myelopathy in elderly patients is safe and effective.
