髂腹股沟骨皮瓣修复虎口挛缩及一期拇对掌功能重建

目的探讨手部损伤后虎口严重挛缩及拇对掌功能障碍者,应用髂腹股沟骨皮瓣开大虎口,一期重建拇指对掌功能的手术疗效。方法2003年7月-2006年2月,对5例虎口严重挛缩伴拇对掌功能障碍的患者采用髂腹股沟骨皮瓣修复虎口挛缩的同时一期行骨性拇对掌功能重建,其中男4例,女1例;年龄20-38岁。挤压伤术后3例,腕关节离断伤和爆炸伤术后各1例。虎口平均宽度为18mm,虎口角平均为20°,病程6-24个月。术后进行临床观察及随访。结果术后5例患者皮瓣全部成活,术后3周断蒂,8周X线片示髂骨与第1、2掌骨骨性愈合,移植骨无变形及吸收。随访6-12个月,虎口角平均增大60°,虎口宽度平均增大32mm,持物功能恢复良好。结论采取髂腹股沟骨皮瓣修复虎口挛缩的同时一期行骨性拇对掌功能重建,是一种相对简便安全,疗效可靠的手术方式。

CLINICAL APPLICATION OF GROIN SKIN AND ILIAC BONE COMPOSITE GRAFT IN CONTRACTURE OF FIRST WEB SPACE AND RECONSTRUCTION OF POLLICIS OPPONENS FUNCTION

OBJECTIVE: To investigate the therapeutic effects of the groin skin and iliac bone composite graft on the repair of severe contracture of the first web space and one-stage reconstruction of the pollicis opponens function under the condition of no ideal muscle or tendon used. METHODS: From July 2003 to February 2006, 5 patients (4 males, 1 females; age range, 20-38 years) with severe contracture of the first web space with loss of the pollicis opponens function were treated by the groin skin and iliac bone composite graft, with the clinical observation performed. The defect was caused by a crush injury in 3 patients, by an explosion injury in 1 patient, and by a wrist joint mutilation injury in 1 patient. They all had been treated by operation at least once with a disease course of 6-24 months. The width and the angle of the first web space was 18 mm and 20 degrees on average. RESULTS: The followed-up for 6-12 moths revealed that all the flaps had a success. The pedicle of the groin skin and iliac bone composite graft was cut off after 3 weeks, and 8 weeks later there was a bone union between the imbedded bone block and the first and second metacarpal bones. There was no evidence that the imbedded bone block was deformed or absorbed. The width of the first web space was augmented by an average of 32 mm, the angle of the first web space was augmented by an average of 60 degrees. The pollicis opponens function recovered. CONCLUSION: It is relatively simple and reliable to repair the contracture of the first web space and reconstruct the pollicis opponens function in one-stage using the groin skin and iliac bone composite graft.
