The results of correction of 39 paralytic claw-thumbs in 34 leprosy patients with combined ulnar and median nerve paralysis by transfer of the flexor superficialis tendon through a small window in the flexor retinaculum are reported. The motor tendon was split into two slips, one passed lateral and the other volar to the metacarpophalangeal joint of the thumb. Both slips were sutured to the tendon of the extensor pollicis longus. The volar slip was used in an attempt to restore muscle balance at the metacarpophalangeal joint. Satisfactory abduction was obtained in 90 percent of the cases, and excessive tip flexion during abduction-opposition was abolished in 85 percent of the cases. However, undesirable flexion of the proximal phalanx occurred in 10 thumbs when held actively in abduction-opposition.
报告了通过屈肌支持带小窗口转移指浅屈肌腱对34例尺神经和正中神经联合麻痹的麻风病患者的39个麻痹性爪形拇指进行矫正的结果。运动肌腱被分成两束，一束从拇指掌指关节的外侧穿过，另一束从掌侧穿过。两束均缝合至拇长伸肌腱。使用掌侧束试图恢复掌指关节的肌肉平衡。90%的病例获得了满意的外展，85%的病例在外展-对掌时拇指尖过度屈曲消失。然而，在主动保持外展-对掌时，10个拇指出现了近端指骨不必要的屈曲。
