【摘要】 改良小指固有伸肌腱移位重建拇对掌功能是治疗陈旧性正中神经损伤致拇对掌功能障碍的很多方法之一,为了解该治疗方法的远期效果是否优良,实验回顾性分析了2003-01/2007-12北华大学附属医院手外科接受过利用改良小指固有伸肌腱移位重建拇对掌功能患者97例,进行随访21例。应用《手功能评定标准的改定》的标准进行术后拇对掌功能的功能评定,测量患手拇指的长度T、拇指对掌活动中向掌心移动(mo)与离掌心移动(Mo):即手掌及4指在冠状面处于伸直位,拇指向掌侧尽量外展并与示指处于同一个矢状面内,测量拇指掌侧指间横纹中点(简称E点)至中指掌指关节掌侧横纹中点(简称F点)之间的的连线距离(简称该距离为Mo)。拇指对掌功能重建后,测量患手拇指的长度及向掌心活动、离掌心活动拇指掌侧指间横纹中点至中指掌指关节掌侧横纹中点的距离,并分别计算它们间的比值。本组病例随访时间为1～14年,平均7.5年,可见利用改良小指固有伸肌腱移位术是重建拇对掌功能的良好治疗方法。更多还原

【Abstract】 Reconstructing thumb opposition function using modified transfer of proper extensor tendon of the fifth digit is one of the methods to treat old median nerve injury-induced thumb opposition dysfunction.To explore the long-term effect of this method,97 patients undergoing modified transfer of proper extensor tendon of the fifth digit to reconstruct thumb opposition function in Department of Hand Surgery,Affiliated Hospital of Beihua University between January 2003 and December 2007 were retrospectively analyzed,and 21 were followed up.The thumb opposition function postoperatively was evaluated using Changing of Hand Function Evaluation Standard.After reconstructing thumb opposition function,length of thumb (T),distance moving to (mo) and moving away from (Mo) centre of palm in opposition,i.e.during closing and leaving centre of palm distance between middle point of thumb interdigit transverse striation and middle point of middle finger MP joint transverse striation.In addition,their ratios were calculated.The patients were followed-up for 7.5 years (ranging 1-14 years).It is a good therapy to reconstruct thumb opposition function using modified transfer of proper extensor tendon of the fifth digit.更多还原
