钢板内固定在脊髓型颈椎病前路减压植骨术中的应用

目的 分析颈椎前路减压自体髂骨植骨钢板内固定术治疗脊髓型颈椎病的临床疗效。方法 对32例脊髓型颈椎病患者行颈椎前路减压自体髂骨植骨钢板内固定术，并对其临床结果进行JOA疗效评定及影像学分析。结果 32例前路植骨于11－18周骨性愈合，术后无椎间高度丢失，颈椎生理曲度维持良好。JOA评分由术前的平均8.4分上升到14.2分。手术有效率为93.8%，优良率为78.1%。结论 颈椎前路减压自体髂骨植骨钢板内固定是脊髓型颈椎病有效的治疗方法，前路钢板具有促进植骨融合，防止术后高度丢失等作用，临床疗效满意。

Application of steel plate internal fixation to cervical anterior decompression and interbody fusion to treating cervical spondylosis myelopathy

Objective To analyse the clinical and radiological outcomes of cervical spondylosis myelopathy treated with anterior decompression and interbody fusion with auto iliac bone grafting and steel plate internal fixation. Methods Thirty two patients with cervical spondylosis myelopathy treated by cervical anterior decompression and interbody fusion with auto iliac bone grafting and steel plate internal fixation were analysed retrospectively. The outcomes were assessed with clinical criteria (JOA) and radiographs of the cervical spine.Results The mean follow|up time of 32 patients was 24 months. All grafting bones got solid fusion from 11to 18 weeks after operation. Intervertebral spaces were restored after operation. The physiological curve of the cervical spine maintained perfectly. The JOA score increased from preoperative mean 8.4 points to postoperative mean 14.2 points. The effective rate of operation was 94.1% and the excellent rate was 79%. Conclusion Results demonstrated that the technique described above is an effective method for treating cervical spondylosis myelopathy.Anterior steel plate internal fixation can promote graft bone fusion and prevent postoperative loss of intervertebral space. The clinical results appear promising.
