拉长式弹性牵引矫治烧伤后爪形手畸形

Correction of claw hand deformity after burns by elastic traction

目的 探讨修复烧伤后爪形手畸形的新途径.方法 2006年5月至2010年7月,对12例瘢痕切除松解植皮或皮瓣移植术后畸形矫正不满意的烧伤爪形手,应用个性化手功能支具结合橡皮筋、指端克氏针（或粘胶带）对手指进行拉长式弹性牵引.结果 术后随访0.5～2年,弹性牵引对烧伤爪形手中存在的掌指关节过伸畸形、近侧指间关节屈曲畸形、虎口挛缩均有效果,可将屈曲短缩的手指拉长,也有利于掌弓复位.少部分（8/28）拉长复位的近侧指间关节屈曲畸形复发或关节不稳,需关节融合.结论 拉长式弹性牵引是矫治烧伤后爪形手畸形的有效方法,损伤小,效果较稳定.

Objective To investigate a new method for correction of claw hand deformity after burns. Methods From May 2006 to Jul. 2010, 12 patients with claw hands deformities after burns were treated with skin grafts （11 hands） and skin flap（1 hand） with unsatisfactory results. Then elastic traction （skin traction or skeletal traction） were performed with individual functional brace. Results All patients were followed up for 0. 5 to 2 years. Elastic traction was effective in the correction of metacarpophalangeal joint deformity, buttonhole deformity, thumb-in-palm deformity, scar contracture, and palmar arch deformity. Conclusions Elastic traction is a simple and effective way for the correction of claw hand deformity after burns with less morbidity and stable results.
