目的　探讨肱骨远端解剖型锁定接骨板（DHP）治疗老年肱骨远端骨折的治疗方法及疗效。  方法　  2007年7月~2010年2月，采用切开复位DHP内固定治疗老年肱骨远端骨折30例，其中男12例，女18例；年龄60～80岁，平均72 岁，骨折按AO分型：A型 1 例，B型 7 例，C1型 5 例，C2型 　10 例，C3型 7 例。均采用DHP固定，术后第3d开始功能锻炼，所有患者按照Mayo肘关节功能评分评估疗效。  结果　24例患者获得11～30个月（平均 17 个月）随诊。骨折均获愈合。肘关节平均屈、伸(78±17.08)°（10°～135°）：屈曲(102±11.35)° （90°～135°）、伸直(20±8.20)°（0°～60°）。Mayo评分平均85.3分（60～100分），其中优 11例，良 10 例，可 2 例，差 1 例，优良率为87.5%。3例出现暂时性尺神经麻痹，3例出现创伤性关节炎表现，1例骨折延迟愈合导致肘关节僵硬，2例发生异位骨化，3例发生轻度肘关节内翻畸形。  结论　DHP内固定治疗老年肱骨远端骨折能达到满意的稳定固定，允许早期功能锻炼，在骨折愈合及功能恢复方面取得满意效果。

Objective　 To summarize surgical techniques and effects of AO distal humeral plate used as a treatment alternative for fracture of distal humerus.　Methods　From July 2007 to Feb. 2010, 30 cases of fracture of distal humerus were treated with open reduction and internal fixation with AO distal humeral plate (DHP). They were 12 males and 18 females. Their ages ranged from 60 to 80 years (average, 72 years). According to AO classification, 1 case was Type A, 7 were Type B, 5 were Type C1, 10 were Type C2, 7 were Type C3. Functional exercises began on the third day after operation. Functional results were evaluated according to the Mayo elbow performance score (MEPS).　Results　24 patients were followed up for 11 to 30 months (average, 18 months). All fractures achieved complete union. The average ulnohumeral motion was (78±17.08）° (range, 10° to 135°), flexion （102±11.35）°(range, 90° to 135°), extension （20±8.20）°(range, 0° to 60°). The average MEPS was 85.3 points (range, 60 to 100 points). 11 cases were graded as excellent, 10 as good, 2 as fair, 1 as poor. 87.5% of the patients had an excellent or good functional result. 3 cases reported transient ulnar nerve paralysis, 3 slight symptoms of traumatic arthritis, 1 delayed union and elbow stiffness, 2 heterotopic ossification, 3 slight malformation.　Conclusions　AO distal humeral plate is a preferred treatment for fracture of distal humerus in the aged because of satisfactory bone healing, early mobilization, union of fracture and recovery of joint function.
