国际手外科协会对手的功能评定标准规定，拇指占全手功能的４０％，拇对掌功能又占拇指功能的６０％［１］，由此可见，拇对掌功能在手功能中占有相当重要的地位。解剖学上拇短伸风与揭短展肌止点相邻，二者属协同肌。受此启发，我们对拇短伸肌重建拇对掌功能进行了研究。临床 International Hand Surgery Association opponents functional assessment standards, the thumb accounted for 40% of the hand function, thumb and palm function accounted for 60% of the thumb function [1], we can see that the thumb and palm function in hand function occupies a very important Position. Anatomy of the thumb short wind and exposing the short side of the knuckles, both are synergistic muscle. Inspired by this, we performed a study of thumb hallucination in thumb extensors. clinical
