Abstract:
Objective:To investigate the effects of the dorsal branch of digital artery pedicled flap combined with V-Y advancement flap for repair of degloving injury of fingertip and reverse dorsal metacarpal recurrent artery pedicled island flap for relaying repair of the soft tissue defects in the donor sites of the proximal dorsum.Methods:A total of 21 patients with degloving injury of fingertip at the 2nd to 5th finger were hospitalized in the Department of Hand Surgery of the Second Hospital of Tangshan from June 2016 to January 2019, including 14 males and 7 females with ages ranging from 24 to 60 years. The retrospective clinical follow-up study was conducted. The areas of wounds after debridement ranged from 2.0 cm×1.5 cm to 3.5 cm×2.2 cm. The dorsal branch of digital artery pedicled flaps with dorsal branch of the proper digital nerve and dorsal digital nerve were designed in the proximal dorsum of the affected fingers to repair dorsal wounds in the distal dorsum of the affected fingers, and the sizes of the flaps ranged from 1.6 cm×1.5 cm to 2.6 cm×2.4 cm. The V-Y advancement flaps in the palmar side of the affected fingers were designed to repair palmar wounds in the distal segment of the affected fingers, and the sizes of the flaps ranged from 0.8 cm×0.6 cm to 2.0 cm×1.5 cm. The reverse dorsal metacarpal recurrent artery pedicled island flaps were used to repair the soft tissue defects in the donor sites of proximal dorsum, the sizes of the flaps ranged from 1.8 cm×1.7 cm to 2.8 cm×2.6 cm, and the donor sites of the flaps in back of hand were sutured directly. The survivals after the operation and the blood supply and appearance during follow-up of the three flaps were observed. At the final follow-up, the static two-point discrimination distance of the flaps was measured, the satisfaction degree of patients for the appearance of hand was evaluated based on Michigan Hand Function Questionnaire, and the total active range of motion of the injured fingers joint was assessed by the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association.Results:All flaps survived after operation. Tension blisters appeared on surface of one dorsal branch of digital artery pedicled flap, and the wound healed after removing the stitch at the pedicle and changing dressings. During follow-up of 6-20 months, with an average of 12 months, three kinds of flaps had good appearance, soft texture, and similar color with surrounding tissue, and there was only linear scars in donor site of the dorsal hand. At the final follow-up, the static two-point discrimination distances of V-Y advancement flaps, dorsal branch of digital artery pedicled flaps, and reverse dorsal metacarpal recurrent artery pedicled island flaps were 4-7 mm, 5-10 mm, and 8-15 mm, respectively. Sixteen patients were strongly satisfied and the remaining five patients were satisfied with the appearance of hand. The total active range of motion of the injured fingers joint was evaluated as excellent in 17 cases, good in 4 cases.Conclusions:The operation is simple and reliable for dorsal branch of digital artery pedicled flap combined with V-Y advancement flap to repair the degloving injury of fingertip, and reverse dorsal metacarpal recurrent artery pedicled island flaps to repair the soft tissue defects in the donor sites of the proximal dorsum, and the appearance and function of the affected fingers recover well, with minimal subsidiary-injury.
