Abstract:
Objective:To investigate the effects of thinned anterolateral thigh perforator flaps combined with finger splitting and webplasty in sequential treatment of degloving destructive wound of total hand.Methods:This study was a retrospective observational study. From January 2012 to January 2023, a total of 15 cases who met the inclusion criteria with degloving destructive wound of total hand were admitted to Ningbo No.6 Hospital, including 10 males and 5 females, aged 17-75 years. The wounds were all combined with exposed bones or tendon. Emergency debridement and vacuum sealing drainage were performed in all cases before flap transplantation in stage Ⅰ. After thorough debridement, the wound area was 11.0 cm×3.0 cm-23.0 cm×13.5 cm. One or both anterolateral thigh perforator flaps with size of 12.5 cm×5.0 cm-25.0 cm×15.5 cm were designed, cut, and thinned to repair the skin and soft tissue defects of the hand. The donor site was sutured directly or repaired with medium-thickness skin graft from the opposite thigh. As needed, the flap was reconstructed by finger splitting and webplasty once or more times every 3 months after stage Ⅰoperation. The survival and complications of flap and wound healing at the donor site were observed after stage Ⅰoperation. The appearance of flap, two-point discrimination distance, and hand function were observed during the follow-up. At the final follow-up, the function of the affected hand was evaluated by the trial standards for evaluation of partial function of upper extremity by the Hand Surgery Society of Chinese Medical Association.Results:After the operation of stage Ⅰ, all the flaps of 15 cases of patients survived completely, including 1 case that had arterial crisis of flap but survived completely after exploration and re-anastomosis of blood vessels; all the wounds at the donor site healed. During the follow-up period of 6 to 18 months after stage Ⅰ, the flap was slightly swollen, with a little pigmentation, and the two-point discrimination distance in the finger flap was 8-11 mm. The fingers could complete the basic life actions such as flexion, extension, pinch, and grip. At the final follow-up, 3 cases were excellent, 9 cases were good, and 3 cases were acceptable in function evaluation of the affected hand.Conclusions:For degloving destructive wound of total hand, free transplantation of one or both thinned anterolateral thigh perforator flaps is used for repair in stage Ⅰ, and finger splitting and webplasty are used to reconstruct the flaps in the later stage, which can basically restore the pinch and grip function of the affected hand that is required for daily life, and is worthy of clinical promotion.
