【摘要】 目的报告双钢板法治疗肱骨髁间骨折的临床疗效。方法2002年2月至2003年6月,采用双钢板法治疗肱骨髁间骨折22例,男15例,女7例;年龄19～67岁,平均42.2岁。按照Müller的AO分型:C1型5例,C2型11例,C3型6例。受伤至手术时间3～6d,平均4.3d。取肘后正中切口,经尺骨鹰嘴截骨显露肱骨髁间骨折。先将髁间骨折复位固定,其中6例C3型骨折,由于骨折块粉碎,采用了自体髂骨植骨。然后用双钢板固定髁上骨折,内侧半管状钢板固定于内上髁的嵴上,外侧则用重建钢板固定,两钢板呈90°角,鹰嘴截骨部用张力带固定。结果22例患者均获随访,时间13～29个月,平均20.2个月。术后1个月,肘关节屈曲80°～105°,平均86.2°;伸直丢失30°～45°,平均40.7°。术后12个月,肘关节屈曲95°～135°,平均117°;伸直丢失10°～35°,平均23.2°。骨折愈合时间12～20周,平均15.7周。以Jupiter评分系统评价肘关节功能,优3例,良15例,可4例。4例伤口渗出,3例克氏针退出,1例尺神经病变,3例异位骨化。无一例出现切口皮肤坏死、深部感染、内固定松动及断裂。结论双钢板法治疗肱骨髁间骨折能提供牢固持久的固定,有效地防止骨折不愈合或畸形愈合,显著降低相关并发症,促进肘关节功能的恢复。更多还原

【Abstract】 Objective To report the clinical outcome of dual plating in treating humeral intercondylar fractures. Methods From February 2002 to June 2003, 22 cases of humeral intercondylar fractures were treated with dual plating. It involved 15 males and 7 females, whose average age was 42.2 years with a range from 19 to 67 years. According to the AO classification, 5 cases were of type C1, 11 of C2 and 6 of C3. The posterior midline approach was selected, and the intercondylar fracture ends were exposed through the trans-olecranon osteotomy. The intercondylar fragments were fixed first, in 6 cases with C3 type fractures, the auto-grafting from the iliac bone was performed because of comminution, then the supracondylar fracture was fixed with dual plating. The semi-tubular plates was applied on the medial epicondylar crest of the humerus; and the reconstruction plate was implanted on the postero-lateral side, the two plates were kept in 90° with each other. The osteotomized ends were fixed with tension band. Results All the 22 patients were followed up for 13-29 months ( mean, 20.2 months ). By the end of the first postoperative month, the elbow flexion averaged 86.2°( range, 80°-105°), and the loss of extension averaged 40.7°(range, 30°-45°). But at the 12th month, the flexion improved to 117°(range, 95°-135°), and the extension loss decreased to 23.2°( range, 10°-35°). The averaged union time was 15.7 weeks with a range of 12 to 20 weeks. Assessed by the Jupiter scoring system, 3 cases were rated as excellent, 15 as good and 4 as fair. Complications included 4 cases of incision exudation, 3 K-wires withdrawal, 1 ulnar neuropathy and 3 heterotopic ossification. But no incision necrosis, deep infection, loosening or breakage of the internal fixators occurred. Conclusion The dual plating is able to provide stable and durable fixation for the humeral intercondylar fractures. In addition, it can prevent malunion or nonunion effectively, and decrease the related complications significantly. This method is helpful to improve the functional recovery of the elbow joint satisfactorily.更多还原
