Three kinds of skin flaps for hand wound repair:an effectiveness evaluation / 中国组织工程研究

ABSTRACT

BACKGROUND:Donor site, recipient site and operator are three important factors for flap transplantation in the repair of hand soft tissue defects. Depth studies are needed on how to choose flaps according to the principle of“good reconstruction of the recipient site, little damage to the donor site, reliable survival, simple and easy operation”. OBJECTIVE:To compare the repairing effects of pedicled neurovascular fasciocutaneous flap, abdominal skin flap and free flap, thereby providing a reference for clinical choice. METHODS:Twenty-eight patients who underwent transplantation of pedicled neurovascular fasciocutaneous flap, abdominal skin flap and free flap in the repair of hand defects, respectively, were al fol ow-up to compare and analyze the disability of the arm, shoulder and hand (DASH), injured site, touch and pressure sensation (Semme-Weinstein monofilament method), dynamic and static two-point discrimination (m2PD, s2PD), temperature sensation, swel ing degree, and degree of scar contracture at donor sites. RESULTS AND CONCLUSION:No significant difference in the degree of scar contracture, temperature sensation, touch sensation, and two-point discrimination was found among the three kinds of flaps, but DASH score, swel ing degree and tough and pressure sensation in the abdominal skin flap group were significantly different from those in the other two groups. These findings indicate that these three kinds of flaps have their own characteristics, and can be selected clinical y based on a variety of objective requirements.
