尺骨鹰嘴截骨垂直双钢板固定治疗C型肱骨远端骨折

Perpendicular Double Plate Fixation to Treat AO Type C Fractures of the Distal Humerus

目的：探讨经尺骨鹰嘴截骨垂直双钢板固定治疗C型肱骨远端骨折的方法和临床疗效。方法：2005年7月--2012年11月采用经尺骨鹰嘴截骨入路垂直双钢板固定治疗c型肱骨远端骨折36例。骨折按照A0／ASIF分类：G8例，C216例，C312例。结果：36例获得随访，时间5～28个月，平均14．3个月。骨折全部愈合，愈合时间12～20周，平均15．8周，无切口感染、内固定松动及断裂等。疗效参照改良的Cassebaum法评估：优10例，良19例，可3例，差4例；优良率80．6％。结论：经尺骨鹰嘴截骨垂直双钢板固定治疗c型肱骨远端骨折，稳定性好，可早期进行关节功能锻炼，疗效好。

Objective：To explore the surgical managements and clinical effects in patients with AO type C fractures of the distal humerus treated using perpendicular double plating methods through olecranon osteotomy approach. Meth- ods： From July 2005 to November 2012,36 patients with type C fractures of the distal humerus were treated using per- pendicular double plating method through olecranon osteotomy approach. According to AO/ASIF classification, there were 8 cases of type Ca, 16 cases of type C4,12 cases of type Ca. Results： All patients were followed up for 5~28 months （average 14. 3 months）. All fractures healed. The healing time was 12~20 weeks（average 15.8 weeks）. There was no incision infection and failure of osteosynthesis. According to Cassebaum scoring system, there were 10 excellent cases, 19 good,3 fair and 4 poor. The excellent and good rate was 80. 6%. Conclusion.-Perpendicular double plating through olecranon osteotomy approach has advantages of stable fixation, early functional exercise and good clini- cal effects, is an ideal methods for treating AO type C fractures of the distal humerus.
