带蒂尺动脉腕上皮支皮瓣修复对侧手指脱套伤

目的探讨采用上、下行联合的带蒂尺动脉腕上皮支皮瓣修复对侧手指脱套伤的疗效。方法 2005年8月-2009年8月,收治11例单指脱套伤患者。男8例,女3例;年龄19～55岁,平均26岁。机器绞伤9例,交通事故伤2例。损伤指别:拇指1例,示指7例,中指3例。皮肤撕脱范围均为自手指近节或中节以远完全撕脱,皮肤缺损范围5.0 cm×4.5 cm～8.0 cm×5.5 cm。合并指骨骨折2例,伸肌腱损伤3例,伸、屈肌腱损伤1例,指血管损伤9例,指神经损伤6例。患者受伤至手术时间为2～18 h,平均4.8 h。术中设计以肘窝内侧缘至腕部尺动脉搏动点(豌豆骨)的连线为皮瓣轴线,豌豆骨近端约4 cm处(尺动脉腕上皮支入点)为共同蒂部作远、近侧各一舌形皮瓣,下行皮瓣附于掌侧,上行皮瓣附于背侧,完全包绕脱套指缝合。皮瓣切取范围10 cm×3 cm～16 cm×3 cm。供区直接缝合。于皮瓣修复术后3周断蒂。结果术后3 d 1例皮瓣边缘出现少许浅黄色分泌物,皮瓣表面有湿疹,经换药2周后分泌物消失,皮疹逐渐消退;其余皮瓣均顺利成活,创面Ⅰ期愈合。供区切口均Ⅰ期愈合。术后3个月2例因皮瓣外观臃肿,行二期修整手术。术后患者均获随访,随访时间6～12个月,平均8个月。皮瓣质地优良,色泽正常,无破溃。术后6个月皮瓣两点辨别觉为12～20 mm;手指功能采用Jebsen手功能评定标准,获优8例,良2例,差1例。结论上、下行联合的带蒂尺动脉腕上皮支皮瓣血供可靠,切取容易,供区损伤小,修复术后手功能及外观佳,是修复手指脱套伤的较好方法之一。
