ABSTRACT

Objective:To investigate the surgical method and clinical effect of one-stage repair of soft tissue defects of dorsum of hand and multiple fingers by using the polyfoliate conjoined anterolateral thigh perforator flap (ALTP) .Methods:From November, 2015 to September, 2019, 9 cases of soft tissue defects of dorsum of hand and multiple fingers were treated, including 8 males and 1 female. The average age was 32 years old. Causes of injury 4 cases of thermal injury, 3 cases of strangulation injury, and 2 cases of traffic accident injury. Location of injury 7 cases of right hand, 2 cases of left hand. Three cases of dorsum of hand with 1st-4th fingers, 3 cases with 2nd-5th fingers, 2 cases with 2nd-4th fingers, and 1 case with 3rd-5th fingers; All with bone, joint and tendon exposure. There were 6 cases with fracture or joint dislocation. All of them had no obvious defect of bone and joint. VSD was used to cover them after debridement. According to the shape and size of the wound, all flaps were designed to repair the soft tissue defect as the polyfoliate conjoined ALTP. The flap size was 7 cm×13 cm-12 cm×17 cm. Regular outpatient, telephone and Wechat follow-up were carried out to evaluate the flap survival, appearance, color elasticity, donor scar, sensory recovery, finger function recovery and patient satisfaction.Results:Nine cases of flap survived well. The average followed-up time was 12 (6-18) months. The postoperative followed-up revealed satisfactory shapes of the flaps, protective touch and recovery of functions. The donor site had good healing and no effect on function. In the last followed-up, according to the trial criteria for function evaluation of upper limbs by Chinese Society of Hand Surgery, 5 cases were excellent, 3 cases were good, and 1 case was fair. The hand function recovered well and returned to work and daily life on average 6 weeks after operation.Conclusion:The polyfoliate conjoined ALTP can repair the soft tissue defect of hand dorsum with multiple fingers at one stage, and the flap is in good shape. There is no need to divide the fingers. It is one of the ideal methods to repair the soft tissue defect of hand dorsum.
