Objective To explore the surgical management and its results of type C fracture of distal end of humerus through approach of osteotomy of olecranon with dual locking compression plate. Methods 31 patients with fractures of the type C fracture of distal end of humerus were treated by using dual locking compression plate. Functional recov-ery of the elbow joint was assessed using Cassebaum rating scale score. Results All the patients were followed up for 12~24 months. All the fractures and the osteotomy of olecranon got solid bony union eventually. The function of the joint showed excellent in 11 cases, good in 15, fair in 3 and poor in 2(myositis ossificans),and the excellent-good rate was 83. 9%. Conclusions The technique of dual locking compression plate for the treatment of type C fracture of distal end of humerus through approach of osteotomy of olecranon has many advantages,such as sufficient exposure, easy to get anatomical reduction,stable fixation and earlier exercise.%目的 探讨经尺骨鹰嘴截骨入路双侧锁定加压钢板治疗肱骨远端C型骨折的方法及疗效.方法 采用经尺骨鹰嘴截骨入路双侧锁定加压钢板治疗31例肱骨远端C型骨折患者. 采用改良Cassebaum评分系统评价肘关节功能. 结果 31例均获得随访,时间12~24个月. 末次随访时X线片示骨折处及鹰嘴截骨处全部愈合. 关节功能:优11例,良15例,可3例,差2例(并发骨化性肌炎) ,优良率83. 9%. 结论 经尺骨鹰嘴截骨入路可以充分显露肱骨远端,有利于解剖复位粉碎的关节面;双侧锁定加压钢板固定骨折块,牢固可靠,可满足肘关节早期功能锻炼.
