急性肘关节后脱位伴尺骨冠状突骨折的手术治疗

Treatment of acute posterior elbow dislocation associated with coronoid fractures

目的 探讨急性肘关节后脱位伴尺骨冠状突骨折的不稳定性和手术内固定的必要性。方法 分析12例急性肘关节后脱位伴尺骨冠状突骨折的损伤特点 ,根据其分类采取相应的措施进行修复和内固定。结果 12例患者均获 12～ 2 4个月的随访 ,无一例发生关节僵直、半脱位和再脱位。结论 尺骨冠状突对肘关节的稳定起重要作用 。

Objective To investigate the unstable characteristics and necessity of internal fixation for acute posterior dislocation of elbow associated with ulnar coronoid fractures. Methods The injury features of acute posterior dislocation of the elbow associated with ulnar coronoid fractures in 12 cases were analyzed retrospectively, and corresponding measures were adopted to repair them according to the classification. Results The patients were followed up for 12～24 months. No stiffness, subluxation or recurrent dislocation was found. Conclusion The study demonstrates the critical importance of the ulnar coronoid process for elbow stability and the posterior dislocation of the elbow associated with coronoid fractures should be concerned and treated effectively.
