颈前路开槽式减压植骨内固定治疗脊髓型颈椎病

Treatment of Cervical Spondylotic Myelopathy Through Anterior Cervical Decompression Approach with Sectile Trongh Technique,Autograft Fusion and Interal Fixation

目的:探讨颈前路开槽式减压植骨内固定治疗脊髓型颈椎病。方法:对48例脊髓型颈椎病采用经颈前路开槽式减压加自体髂骨植骨内固定,术后定期X线检查并随访所有病例。结果:随访时间平均23个月,植骨于术后3个月骨性愈合,无植骨块移位、钢板断裂或螺钉松动、脱出及断裂等,椎体间高度得到恢复并可维持良好的颈椎生理曲度。手术有效率为100%(48/48),优良率为89.6%(43/48)。结论:脊髓型颈椎病经前路开槽式潜行充分减压,使脊髓功能尽可能恢复,植骨内固定使颈椎更稳定,也利于植骨节段融合,其临床疗效更趋满意。

Objective： To observe the clinical effect of anterior cervical decompression, autograft fusion and interal fixation on treating cervical spondylotic myelopathy （ CSM ）. Method： 48 cases of CSM patients treated surgically by sectile trough technique ,autograft fusion and interal fixation were retrospectively reviewed. And the clinical and radiological follow -up performed pestoperatively were utilized to evaluate this kind of operation. Result： Preoperative symptoms obviously alleviated or disappeared in most patients . Immediate postoperative X- ray films showed the obvious improvement in intervertebral height of the cervical spine and no loss during the mean follow - up 23 months （ 6 - 88months ）, and no instrument failure was detected . The effective rate is 100% （48/48 ） ,including 89.6% （43/48 ） of excellent and good effective rate . Conclusion： The operative method of anterior cervical decompression by trough technique, autograft fusion and interal fixation is a rational and effective method for the surical treatment of CSM. The long - term results of the kind of operation showed it has effect in effective decompression, effective autograft fusion , and good cervical spine stabilization.
