目的 探讨切开复位、板钉内固定和肘关节置换手术治疗肱骨髁间骨折的疗效.方法 1999年1月至2009年5月期间经手术治疗的肱骨髁间骨折患者46例,经过平均17个月的随访,随访到38例.对所有随访患者进行Cassebaum评分,对关节置换患者加用Mayo评分和DASH评分.结果 采用Cassebaum评分标准评估患者的疗效,其中优22例,良8例,可5例,差3例,优良率为78.9%（30/38）;关节置换患者Mayo评分为75.0～90.0分,平均（84.4±1.7）分;DASH评分为25.0～75.0分,平均（41.1±0.8）分.1例鹰嘴截骨患者出现鹰嘴不愈合,1例伤口不愈合,2例有尺神经症状,1例肘关节屈伸肌力Ⅳ级.结论 根据骨折分型及患者情况合理运用内固定和肘关节置换是治疗肱骨髁间骨折的良好方法.

英文摘要：

Objective To assess the efficienty of operation in humeral intercondylar fractures by section, reposition, internal fixation by composition nail and replacement of elbow joint. Methods From January, 1999 to May, 2009, Forty-six cases of the humeral intercondylar fracture were treated with operation. Thirty-eight cases were followed for 17 months. Their affected elbow joint function were evaluated by Cassebaum rating system, patients treated with total elbow replacement evaluated by Mayo elbow score, DASH score additionally. Results According to Cassebaum rating system,there were 22 cases rated as excellent,eight cases rated as good,five cases rated as poor,three case rated as poor. The fineness rate is 78. 9% （30/38）. Mayo score in patients with joint replacement ranged from 75.0 - 90. 0, averaged 84. 4 ± 1.7. DASH score ranged from 25.0 to 75.0,averaged 41. 1 ±0. 8. There was 1 case of superficial soft tissue nonhealing and 2 cases of ulna nerve symptoms. Myodynamia in elbow joint bend and stretch was Ⅳ in 1 cases. Conclusion It is a good method to treat the humeral intercondylar fracture with rational use of open reduction or elbow replacement according to fracture type and patient condition.
