| ［摘要］ 目的 探讨应用Cervifix内固定系统治疗上颈椎骨折、脱位的效果。方法 对12例上颈椎损伤患者(其中寰枢关节陈旧性脱位3例，寰枢关节新鲜脱位3例，枢椎齿状突骨折2例，C2椎体骨折并寰枢关节半脱位2例，C2～3椎体骨折2例)行后路切开、复位、Cervifix内固定，并行自体髂骨植骨。术前按ASIA分级：A级2例，B级4例，C级5例，D级1例。结果 12例患者均获随访，随访时间8 M～5 a,平均2.7 a。所有病例植骨均融合，植骨融合率100%。无1例发生Cervifix螺钉及固定棒松动、断裂等并发症。术后1年ASIA分级：A级1例，B级2例，C级3例，D级6例。瘫痪分级明显好于术前，差异有统计学极显著意义(P<0.01)。结论 Cervifix内固定系统能够有效地维持上颈椎损伤修复所要求的稳定性，固定效果良好，内固定后融合率高。 |

| Abstract: |
| ［Abstract］ Objective To study the clinical effects of using cervifix internal fixation system on upper cervical spine injuries.Methods Twelve patients with upper cervical injuries were fixed using cervifix internal fixation system with autologous bone grafts,including 3 patients with old atlantoaxial dislocation,3 patients with acute atlantoaxial dislocation,2 patients with fracture of the dentoid process of axis，2 patients with fracture of C2 vertebra and accompanied atlanto-axial incomplete dislocation,2 patients with fracture of C2,C3 vertebra.Graded by ASIA:A 2 patients, B 4 patients, C 5 patients, D 1 patient.Results All patients were followed up postoperatively for 0.8～5 years, with an average of 2.7 years.All patients had solid osseous unions, the rate of fusion was 100%.There were no complications of lossening and rupture of the internal fixation rods and screws.Graded by ASIA:A 1 patients, B 2 patients, C 3 patients, D 6 patients, the recovery of paralysis was significant in post-operations（P<0.01）.Conclusion Cervifix internal fixation can provide rigid stability of upper cervical injuries, the effect of fixation is well and the rate of fusion is high. |
