摘要
目的 探讨非外伤性上颈椎不稳定的手术治疗效果。 方法 1998年1月～2 0 0 3年3月治疗非外伤性上颈椎不稳定2 3例,其中C1 、C2 肿瘤破坏3例,寰枕融合畸形3例,先天性齿状突不融合2例,单纯寰枢关节半脱位15例。采用寰枢椎融合术10例,其中Apofix固定5例,钢丝Brookes法固定2例,Atlas钛缆固定3例;枕颈融合术13例,其中Cervifix固定8例,CD- Cervical固定3例,U形棒固定2例。寰枢椎Apofix或Atlas钛缆固定者,取棘突松质骨行C1 、C2 骨屑植骨,余15例取自体髂骨外板行燕尾状大块植骨。 结果 2 3例均获随访6个月～5年,平均2 .5年,全部达骨性融合,时间3～8个月。2 0例术前合并神经系统受损症状者,术后6个月16例症状明显改善,4例无改善。根据JOA评分标准,平均术后改善率为2 7.1%。
Objective To study operative methods of treating upper cervical spine instability without injury. Methods Twenty three cases were treated by internal fixation with autologous bone grafts. Atlantoaxial arthrodesis were performed in 10 cases with Apofix interlaminar clamp(5 cases), Atlas cable system(3 cases) and Brookes(2 cases). Occipitocervical fusion were performed in the other 13 cases by using of CD cervical(3 cases), Cervifix(8 cases) and U stick fixation(2 cases). Results All the 23 cases were followed up for 2.5 years in average (ranged from 6 months to 5 years). Solid arthrodesis was obtained in all 23 cases . Six months after operation, of the 20 cases with pre operation nervous lesion, improvement was achieved in 16 cases. According to JOA standard and Hirabashi formula, the rate of improvement was 27.1%.Conclusion Posterior fusion is recommended for upper cervical unstability.
