切开复位治疗高位髁状突骨折

High Condylar Fractures Treated by Open Reduction

目的 探讨切开复位治疗高位髁状突骨折。方法 对 32例 (47侧 )高位髁状突骨折经耳前进路行髁状突复位、微型钛板内固定 ,术后行临床和影像学观察。结果 术后 1年临床评价优良率为 75 % ,无张口受限、关节症状及面神经损伤 ,影像学检查髁状突异常主要有骨折片移位、成角畸形及骨质吸收 ,再移位仅见于单板固定的病例。结论 切开复位治疗高位髁状突骨折可取得满意临床疗效 ,内固定时尽可能行双板固定 ,以达到三维稳固。

Objective To evaluate the effects of open reduction and miniplate rigid fixation on high condylar fractures. Methods 32 patients with high condylar fractures were treated by open reduction and miniplate rigid fixation. The curative effect were evaluated by clinical examination and radiography. Results 75% cases got satisfactory results in one-year-follow-up. There were no facial nerve damages and limitation of mouth opening. Radiographic examination showed that redisplacement of condylar fragment, fractured bone resorption and inaccurate reduction were only observed in the cases fixed with single miniplate. Conclusion High condylar fractures can be successfully managed by open reduction and miniplate rigid fixation.
