Abstract:
Objective:To investigate the clinical effects of modified fascia flap from cutaneous branch of dorsal metacarpal artery in repairing the wound at the proximal and middle finger segments.Methods:From January 2017 to September 2018, 12 patients with wounds at the proximal and middle finger segments were admitted to the Affiliated Hospital of Zunyi Medical University, including 8 males and 4 females, aged 35-70 years. The areas of wounds ranged from 3.4 cm×2.4 cm to 6.5 cm×4.0 cm. The modified fascia flaps from cutaneous branch of dorsal metacarpal artery were resected to repair the wounds, with the size ranging from 3.5 cm×2.5 cm to 6.7 cm×4.1 cm. The flap donor sites of 5 patients were repaired with direct intermittent suture, the flap donor sites of 4 patients were repaired with full-thickness skin grafts from ipsilateral medial forearm, and the flap donor sites of 3 patients were repaired with wrist pedicled flaps. The survival of the flaps was recorded. Healing of donor site and recipient site was followed. The hand functions were evaluated with trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association.Results:All the flaps survived in 12 cases. During 3 to 12 months of follow-up, the flaps recovered satisfactorily in texture and shape. The donor sites of 11 patients were healed, and the skin graft edge area was partially necrotic in the other patient but healed later after dressing change. The distances of two-point discrimination of the patients ranged from 5.6 to 9.0 mm. Hand functions were evaluated as excellent in 5 cases, good in 4 cases, and fair in 3 cases.Conclusions:Modified fascia flap from cutaneous branch of dorsal metacarpal artery for repairing the wounds at the proximal and middle finger segments has reliable blood supply. The operation is simple and safe with short course of treatment, which is worthy of clinical promotion.
