在拇收肌坏死 ,拇指挛缩病人粘连松解手术中 ,需要切断残余拇收肌纤维。基于担心影响手功能的恢复 ,不易决定手术方式 ,而进行了对 97例手的拇收肌的尸体解剖 ,观察及分析拇收肌的附着点位置及其纤维走向和着力方向 ,判断其对掌作用应大于收拇作用。而对掌功能是由多块肌肉共同完成的 ,缺少拇收肌 ,不会明显影响手的对掌功能。对 5种临床简易功能测量结果显示 ,进行模糊数学综合评判 ,证明切断拇收肌对手的功能仅有轻度影响。
In the rejection of muscle necrosis, thumb contracture in patients with adhesions release surgery, the need to cut off the residual adductor muscle fibers. Based on the fear of affecting the recovery of hand function, it is not easy to determine the surgical method, but 97 cases of the hands of the adductor muscle of the autopsy, observation and analysis of adductor muscle attachment point position and direction of its fiber and focus, to determine its palms The role should be greater than the effect of income. The function of the palm is completed by more than one muscle, the lack of adductor muscle, will not significantly affect the hand of the palm function. Five kinds of clinical simple functional measurement results showed that the comprehensive evaluation of fuzzy mathematics showed that the function of cutting off the adductor muscle had only mild influence.
