目的探讨影响尺骨冠状突骨折及其合并伤疗效的相关因素。方法 随访在我院接受治疗的尺骨冠状突骨折67例患者。平均随访(36±20)个月, 56例患者获得了随访疗效。所有患者随访疗效均进行统计学分析。结果 平均MEPS肘关节评分为80.6分, 各种治疗方案之间有显著性差异。15%尺骨冠状突骨折患者只有通过骨折切开复位内固定术才能重建, 获得一定疗效。33%患者肘关节不稳。肘关节平均屈曲伸直活动度是107°±28°, 前臂旋前旋后活动度是153°±38°。结论 尺骨冠状突骨折采用外固定支架治疗、肘关节制动＞21 d、术中及术后发生并发症, 这三个因素对疗效影响最大。

Objective To evaluate relevant factors for therapeutic results of the coronoid process of the ulna and their concomitant injuries. Methods Sixty-seven patients with fracture of the coronoid process were treated within an 7-year period (2003 to 2010) in this hospital. After an average of (36±20) months, treatment outcomes of 56 patients were acquired. The results were statistically analysed. Results The patients’average MEPS (Mayo Elbow Performance Score) was (80.6±18.0) points, with significant differences between the various therapy strategies. 15% of the coronoid process fractures were reconstructable to a limited extent only by means of osteosynthesis. In 33% of the patients, instabilities remained. The average extension/flexion came to (107°±28°), and pronation and supination (153°±38°). Conclusion The strongest negative prognostic parameters in this patient population are: therapy with an external fixator, immobilisation for more than 21 days, and the occurrence of complications.
