摘要
目的 评价椎板钩加压内固定治疗寰枢椎不稳的临床效果。方法 对寰枢椎不稳者行C1-2 后路自体髂骨植骨、椎板钩(Apofix及Halifix)内固定术。包括齿状突骨折 6例 ,陈旧性齿突骨折伴横韧带断裂 1例 ,齿突骨折骨不连结 1例。术后颈椎X线片检查。结果 随访 3个月～ 5年 ,8例均获得骨性愈合。结论 对寰枢椎不稳可采用寰枢椎后路融合椎板钩内固定术治疗 ,椎板钩内固定术无需椎板下穿越钢丝 ,避免了钢丝断裂及松脱。而术前解剖复位是手术成功的主要措施。
Objective To evaluate the clinical effect of posterior atlantoaxial fusion using interlaminar clamp for atlantoaxial instability Methods The patients with atlantoaxial instability were treated by atlantoaxial arthrodesis with autologous bone grafts using interlaminal clamp fixation(Apofix or Halifix) The reasons for performing operation was acute unstable odontoid fracture(6 patients),old odontoid fracture with a disrupted transverse atlantal ligament(1 patient),nonunion of the odontoid fracture with atlantoaxial instability(1 patient) The outcome was assessed by radiographs of the cervical spine Results The patients were followed postoperatively for 3 months～5 years Eight patients had solid osseous unions Conclusion This study suggests that atlantoaxial instability may be managed by posterior atlantoaxial fusion using interlaminal clamp fixation technique Interlaminar clamp systems avoid the passage of sublaminar wires and do not have the risks of wire breakage or pull-out The preoperative anatomic reduction of atlantoaxial is important procedure to successful operation
