摘要目的 评价Bilhaut-Cloquet术治疗先天性复拇指畸形的临床效果,探讨分析其常见并发症的原因.方法 2006年至2009年,对15例先天性复拇指畸形患儿分别采用经典和改良Bilhaut-Cloquet术进行治疗,随访观察术后并发症并对疗效进行评价.结果 术后15例获得1～20个月的随访,平均6个月.参照Kawabata评分标准:采用经典Bilhaut-Cloquet术者5例,优1例,良3例,差1例;采用改良Bilhaut-Cloquet术者10例,优6例,良3例,差1例.两组中指甲畸形明显者9例,瘢痕挛缩、增生者5例.结论 Bilhaut-Cloquet术是治疗复拇指畸形的有效治疗术式,适合于Ⅰ型对等型多拇;Ⅱ型以上的多拇采用改良Bilhaut-Cloquet术更有利于指间关节(IP)关节活动度的恢复.除了重视关节活动度、稳定性和侧偏畸形的矫正外,指体外观尤其是指甲的精确重建应当得到进一步的重视.

abstractsObjective To evaluate the clinical outcomes of Bilhaut-Cloquet surgical procedure for the treatment of thumb duplication, and investigate the causes of common complications. Methods Bilhaut-Cloquet procedure and modified Bilhaut-Cloquet procedure were carried out in 15 children with congenital thumb duplication during 2006 to 2009. The patients were follow-up postoperatively to observe any complications and assess the results using Kawabata evaluation criterion. Results The 15 children were follow-up for 1 to 20 months (6 months on average) postoperatively. According to Kawabata evaluation criterion, the Bilhaut-Cloquet procedure achieved excellent results in 1 cases, good in 3 cases, and poor in 1 cases. Modified Bilhaut Cloquet procedure achieved excellent results in 6 cases, good in 3 cases, and poor in 1 case. Nine cases had apparent nail deformity and 5 cases were accompanied by cicatricial contracture and hyperplasia. Conclusion The Bilhaut-Cloquet technique is an effective procedure for the treatment of thumb duplication, especially suitable for type Ⅰ thumb duplication. Modified Bilhaut-Cloquet procedure is more conducive to the recovery of IP range of motion when used in type Ⅱ or more severe thumb duplication. Besides joint range of motion, stability, and correction of lateral deviation, appearance of the thumb especially accurate nail restoration should acquire more attention.
