Dorsal foot flap transplantation for skin and soft tissue defects of the hand：survival rate and success analysis / 中国组织工程研究

ABSTRACT

BACKGROUND:Skin and soft tissue defects of hands are easy to appear due to different factors, such as trauma. Flap transplantation is a clinical treatment for soft tissue defects of hands. Dorsal foot flap, which is thicker with constant vessel traveling, is very suitable for repair of hand soft tissue defects. OBJECTIVE: To explore the success rate and survival rate of dorsal foot flap transplantation in the repair of hand skin and soft tissue defects. METHODS: A retrospective analysis was performed on the clinical data of 86 patients with skin and soft tissue defect of hands. These patients were respectively given conventional skin wound skin grafting (control group) and dorsal foot flap transplantation (observational group). Hand appearance, infection rate, perception recovery and complications were observed during the postoperative folow-up. RESULTS AND CONCLUSION:Skin flaps al survived after grafting, and the texture of flaps was good. Patients were satisfied with hand shape and the recovery of hand function. After flap transplantation, one patient had local skin necrosis at the donor region, and the scar healed after dressing; another patient had venous crisis, and was given vascular re-anastomosis. In the observation group, the postoperative appearance was better than that of the control group, the infection rate was lower than that of the control group, the perception recovery was better, and there were fewer complications (P < 0.05). These findings suggest that the dorsal foot flap transplantation is better to repair skin and soft tissue defects in the hand.
