Anatomical study was performed on 20 cadaveric hands and the results showed that M. flexor pollicis brevis overlap the M. abductor pollicis brevis for about half of its width at their origins and the overlapping reduced to about 1/3 of the width at the muscle belly level. The M. flexor pollicis brevis chiefly inserts on the palmar aspect of the base of proximal phalanges. The M. abductor pollicis brevis primarily inserts to the radial side of MP joints, the M. flexor pollicis brevis is entirely innervated by the deep branch of the ulnar nerve. In order to increase the angle bettween longitudinal force lines of these two muscles for 7-9 degrees, the authors transfered the insertion of the M. flexor pollicis brevis to the radial side of the metacarpal-phalangeal joint, so that it gives this muscle the function of opposition. Eight patients had been treated and followed up on average for 12 months. All had fine functional results. This new methodis effective, least traumatizing and does not need transposition of another tendon.
对20具尸体手进行了解剖学研究，结果显示，拇短屈肌在其起点处与拇短展肌重叠约一半宽度，在肌腹水平重叠减少至约1/3宽度。拇短屈肌主要止于近节指骨基底掌侧。拇短展肌主要止于掌指关节桡侧，拇短屈肌完全由尺神经深支支配。为使这两块肌肉的纵力线夹角增加7 - 9度，作者将拇短屈肌的止点转移至掌指关节桡侧，使其具有对掌功能。8例患者接受了治疗，平均随访12个月。所有患者功能恢复良好。这种新方法有效、创伤小，且无需移植其他肌腱。
