摘　　要：目的探索一种修复全手指皮肤脱套伤时既简便又能精确设计皮瓣的新方法。方法利用20具新鲜尸体,建立40例中指全手指脱套伤的分区皮瓣修复模型。分别测量模型指掌、背侧皮肤与创面的长度和远、近端宽度。分别计算掌背侧创面的长度与远近端宽度的比值,经统计学处理后获得皮瓣系数。结果手指脱套伤撕脱皮肤与创面之间存在一个恒定的比例关系,我们暂命其为皮瓣系数。皮瓣长度系数定为1.2,宽度系数定为1.6。结论皮瓣系数能为临床修复全手指皮肤脱套伤提供一个既简便又能精确设计皮瓣的新方法,为临床真正做到缺多少补多少提供基础。Objective To explore a kind of both simple and accurate method of designing skin flaps for repairing degloving finger injuries. Methods The middle fingers were made to the models of degloving injury of the whole finger in twenty flesh cadaveric specimens. We divided the wound and the degloved skin into two parts： the dorsal part and the volar part. The length, the proximal and distal width of the wound and degloved skin were measured. Flap coefficient（=length of skin/length of wound） was calculated from the above data according to flap coefficient. Results There is a constant proportional relationship between skin and wound, which was named flap coefficient. The length coefficient was 1.2, and the width was 1.6. Conclusion The flap coefficient is beneficial for us to simply and accurately design skin flaps for repairing degloving finger injuries.
