拇短屈肌重建拇对掌功能在断腕再植术后的应用

conclusion the new optimal transpositional operation of the flexor pollicis brevis muscle for the reconstruction of thumb opposition is suitable for the patients with late median nerve injury, especially when the ulnar nerve branch to the deep head of the flexor pollicis brevis muscle is uninjured.

结论拇短屈肌移位适用于手部正中神经损伤晚期的患者重建拇对掌功能，尤其适用于支配拇短屈肌深头的尺神经完好的患者。

Profundus nervi ulnaris are muscular branches, which mainly dominates hypothenar muscles, all of the interosseous muscle, third and fourth lumbrical muscles, adductor pollicis muscle and deep head of flexor pollicis brevis muscle.

尺神经深支均为运动肌支，主要支配小鱼际肌、全部骨间肌、第3和4蚓状肌、拇收肌、拇短屈肌深头。

Results: ( 1) Tendinous arch and tendinous band ulnar to the superficial head of flexor pollicis brevis would compress the recurrent branch.

结果：（1）拇短屈肌浅头尺侧存在腱弓及腱纤维束结构，对正中神经返支形成卡压；
