切开复位双钢板内固定治疗肱骨髁间C型骨折

目的 评价切开复位双钢板内固定治疗成人肱骨髁间粉碎性骨折的临床疗效.方法 2004年6月至2007年10月,采用切开复位双钢板内固定治疗肱骨髁间C型骨折38例,其中男性21例,女性17例;年龄21～71岁,平均43岁.按照AO分型:C1型9例,C2型17例,C3型12例.均取肘后正中切口,其中经尺骨鹰嘴截骨显露肱骨髁间骨折21例,采用肱三头肌舌形瓣人路者11例,肱三头肌内外侧入路者6例.5例由于骨折块粉碎严重,采用Ⅰ期自体髂骨植骨.结果 38例患者中35例获得随访,时间14～30个月,平均24.2个月.末次随访时,肘关节屈曲范围90°～135°,平均119°;欠伸直5°～25°,平均16.2°.未发生骨折不愈合,平均愈合时间为14周.根据Aitken和Rorabeck评分标准,优13例,良16例,可6例,优良率82.9%.4例发生创伤性关节炎,2例异位骨化,1例小指一过性麻木.无一例发生切口感染、内固定松动及断裂.结论 双钢板法治疗肱骨髁间粉碎性骨折能提供有效可靠的固定,允许早期功能锻炼,显著降低了相关并发症的发生,促进肘关节功能的恢复.

Treatment of type C intercondylar fractures of distal humerus using dual plating

Objective To evaluate the clinical outcome of dual plating in the treatment of humeral intercondylar type-C fractures in adults. Methods From June 2004 to October 2007, 38 cases of type-C distal humeral fractures were stabilised with dual plating. There were 21 males and 17 females. The average age was 43 years with a range from 21 to 71 years. According to the AO classification, 9 cases were of type C1, 17 of C2 and 12 of C3. The posterior midline approach was selected. Twenty-one cases were exposed through the trans-olecranon osteotomy, 11 through the Campbell (Van Corder) approach, 6 through triceps sparing approach. Autogenous bone graft was performed in 5 cases because of severe comminution. Results Thirty-five patients were followed-up for 14-30 months (mean 24. 2 months). At the latest follow-up, the elbow flexion averaged 119°( range 90°-135°), and the loss of extension averaged 16. 2°(range 5°-25°). All the patients got bony healing, the average healing period was 14 weeks. The patients were evaluated using the criteria of Aitken and Rorabeek and the scores were 13 excellent, 16 good, 6 fair. Twenty-nine patients (82.9%) had a good or excellent results. Complications included 4 cases of traumatic usteoarthritis, 2 heterotopic ossification, 1 ulnar neuropathy. Infection as well as loosening or breakage of the implant was not found. Conclusions The dual plating is able to provide rigid fixation for the humeral intereondylar fractures. In addition, it can allow early functional exercise after operation, decrease the related complications significantly, and improve the functional results.
