前路减压植骨内固定术治疗多节段脊髓型颈椎病

Outcome of Treatment of the Multilevel Anterior Cervical Discectomy and Fusion with Rigid Plate Fixation for Multilevel Cervical Spondylotic Myelopathy

目的：探讨前路减压植骨内固定术治疗多节段脊髓型颈椎病的治疗效果。方法：2002年1月~2009年5月前路减压植骨内固定术治疗多节段脊髓型颈椎病33例,术前和术后JOA评分和恢复率,硬脊膜囊矢状径和膨胀回复率评价临床效果。结果：术后随访7个月~4年6个月（平均8±3.5个月）,本组病例术后JOA评分和硬脊膜囊矢状径较术前比较,差异均有统计学意义（P〈0.05）。结论：前路减压植骨内固定术是治疗多节段脊髓型颈椎病的有效方法之一。

Objective：To explore the clinical outcome of treatment of the multilevel anterior cervical discectomy and fusion with rigid plate fixation for multilevel cervical spondylotic myelopathy.Methods：Thirty three patients with multilevel CSM had been treated by multilevel anterior cervical discectomy and fusion with rigid plate fixation from Jan 2002 to May 2009.All patents were scored with JOA evaluating system and measured the sagittal diameter of dural sac,calculated the recovery rate as well.Results：The follow-up period were 7 months to 4 years and 6 months,averaged 8±3.5 months.There were statistical difference in JOA scores and sagittal diameter of dural sac between post-operative and pre-operative（P0.05）.Conclusion： The multilevel anterior cervical discectomy and fusion with rigid plate fixation is one of the effective methods to treat CSM.
