Abstract: Objective To explore the effect of wrist transverse free flap with palmaris longus tendon in the repair of finger complex tissue defect. Methods From January 2015 to January 2017, a total of 7 cases with composite tissue defects of fingers were concluded in this retrospective study. The finger complex tissue defect was repaired by free wrist transverse flaps with palmaris longus tendon and palmar cutaneous branch of the median nerve in emergency or in secondary stage. The incision of donor sites was closed primarily. Results All flaps were survived. The wounds of the donor site healed by first intention. The patients were followed up for 6 -12 months, the flap was soft with good color and no significant flap bloated appearance, and the static two point discrimination was 3 -5 mm. According to the upper extremity functional evaluation criteria of the Chinese Medical Association of Hand Surgery, 6 cases were excellent, 1 case was good, and the excellent and good rate was 100R. Conclusion This method can not only repair skin and tendon defects in one stage, but also reconstruct the motion and sensory function of the fingers. It can offer good appearance and skin texture, which is recommended to repair finger composite tissue defects.
