Apofix椎板钩治疗创伤性寰枢椎不稳

Posterior atlantoaxial fusion using Apofix interlaminar clamp for traumatic atlantoaxial instability

目的 评价Ａｐｏｆｉｘ 椎板钩治疗创伤性寰枢椎不稳的效果。方法 对创伤性寰枢椎不稳患者行Ｃ１ ～２ 后路融合、Ａｐｏｆｉｘ 椎板钩内固定术。包括齿状突骨折５ 例，其中１ 例伴横韧带断裂。结果 术后随访３ ～１１ 个月，颈椎侧位Ｘ 线片检查，５ 例获骨性愈合。结论 寰枢椎后路融合、Ａｐｏｆｉｘ 椎板钩内固定术适于治疗创伤性寰枢椎不稳；解剖复位是手术成功的主要措施。

Objective To evaluate the effect of posterior atlantoaxial fusion using Apofix interlaminar clamp on traumatic atlantoaxial instability. Methods The patients with traumatic atlantoaxial instability were operated on,including 5 patients with unstable odontoid fractures, one of them with a disrupted transverse ligament.All patients were treated by atlantoaxial arthrodesis using Apofix interlaminar clamp fixation with autologous bone grafts. Results The patients were followed with lateral cervical radiographs for 3～11 months. 5 patients had solid osseous unions. Conclusion Posterior atlantoarial fusion using Apofix interlaminar clamp fixation is recommended for traumatic atlantoaxial instability; the anatomic reduction of atlantoaxial is the key to successful operation.
