Twelve patients (23 digits) with isolated ulnar nerve palsy underwent flexor digitorum superficialis lasso tendon transfers for correction of claw deformity, weakness, and asynchronous digital flexion. The average follow-up period from date of injury was 5 years (range, 2-11 years) and from surgery was 3 years (range, 15 months to 7 years). Transfers successfully corrected the claw deformity in 19 of the 23 digits. Three of the four failures occurred in the small finger. Two of the four failures had uncorrected preoperative proximal interphalangeal joint flexion contractures. In 9 of the 12 patients with pre- and postoperative grip strength measurements no significant improvement in grip strength was noted. While this procedure is effective and predictable in correcting deformity and restoring synchronous pattern of finger flexion, it should be used with caution in patients requiring an increase in grip strength.
12例（23指）单纯尺神经麻痹患者接受了指浅屈肌套索肌腱转移术，以纠正爪形畸形、无力和手指屈曲不同步。从受伤日期起的平均随访期为5年（范围2 - 11年），从手术日期起为3年（范围15个月至7年）。23指中有19指的转移术成功纠正了爪形畸形。4例失败中有3例发生在小指。4例失败中有2例术前近端指间关节屈曲挛缩未得到纠正。在12例术前和术后均测量握力的患者中，有9例未观察到握力有显著改善。虽然该手术在纠正畸形和恢复手指同步屈曲模式方面有效且可预测，但对于需要增加握力的患者应谨慎使用。
