显微技术下颈前入路治疗脊髓型颈椎病

目的探讨颈前入路显微手术治疗脊髓型颈椎病的疗效。方法回顾性分析2014年10月至2016年8月33例采用颈前路椎间盘切除减压融合术（ACDF）治疗脊髓型颈椎病患者的临床资料，以日本骨科学会（JOA）评分（17分法）及其改善率评价患者术前、术后3个月神经功能，评价手术效果。结果患者术后神经功能均明显改善。术前平均JOA评分11．0分，术后3个月平均JOA评分15．4分，差异有统计学意义（P〈0．05）。术后平均改善率73．3％，无脊髓损伤、术后出血等严重并发症、结论显微镜技术颈前入路减压融合术治疗脊髓型颈椎病，视野清晰，止血可靠，同时可恢复颈椎曲度和椎间隙高度，手术创伤小，临床疗效满意。

Objective To evaluate the effect of microscope-guided anterior cervical discectomy with fusion （ ACDF ） in the treatment of cervical spondylotic myelopathy. Method The clinical data of 33 patients with cervical spondylotic myelopathy treated by anterior cervical discectomy with fusion （ ACDF ） in our hospital from 2014 till now were analyzed retrospectively. Japanese Orthopaedic Association （ JOA ） score and its improvement rate were used to evaluate neurologic function after operation. Results All patients were followed up tbr 3 months. JOA score improved significantly from preoperative 11.0 to postoperative 15.4 （ P〈0.05 ） . Conclusions Anterior cervical decompression and fusion by microscope is a refined, safe and effective surgical procedure for cervical spondylotic myelopathy.
