[目的]评估采用三头肌劈开和尺骨鹰嘴截骨两种不同入路下“Y”型钢板治疗肱骨髁间骨折的临床效果.[方法]2005年4月-2008年12月,86例肱骨髁间骨折患者均接受切开复位“Y”型钢板内固定手术,其中43例采用三头肌劈开入路,43例采用尺骨鹰嘴截骨入路.[结果]所有患者随访时间为8～48个月,平均30.6个月.Mayo[1]肘关节评分、上肢、肩、手功能障碍(disabilities of the arm,shoulder and hand,DASH)评分[2]和Knirk评分[3]均显示两组差异无统计学意义(P>0.05).并发症包括6例延迟愈合,1例严重的肘关节僵硬,3例异位骨化,2例尺神经麻痹,1例6个月后恢复,1例留有尺神经麻痹症状.[结论]“Y”型钢板治疗肱骨髁间骨折辅以适当辅助锻炼,大多数患者均能获得良好的疗效,三头肌劈开入路和尺骨鹰嘴截骨入路均可获得相似的临床效果.“,”[Objective]To assess the clinical effect of split triceps approach and olecranon osteotomy approach with Y-recon-struction plate for the treatment of humeral condylar fracture. [Method]From April 2005 to December 2008,86 cases of humeral condylar fracture patients received open eduction and Y-reconstruction plate fixation,43 cases with triceps splitting approach,43 cases with olecranon osteotomy approach. [Result]The follow-up time was 8-48 months, average 30.6 months. Mayo elbow score, DASH(dysfunction disabilities of the ann, shoulder and hand) score and the Knirk score showed no significant difference between the two groups(P > 0.05). Complications included 6 cases of delayed union, 1 cases of severe elbow stiffness,3 cases of heterotopic ossification,2 cases of ulnar nerve palsy, in which one case recovered after 6 months, another case remained symp-toms. [Conclusion]With appropriate training aids, the majority of patients have good effect. Same good clinical outcome have been achieved for treatment of intracondylar humeral fractures with either triceps splitting approach or the olecranon osteotomy ap-proach.
