Objective To investigate the reliability and clinical efficacy of the superficial circumflex iliac artery perforator flap (SCIP) designed on the concept of "swim trunk donor site" in repairing skin and soft tissue defects of extremities. Methods Thirty-eight patients with skin and soft tissue defects of extremities admitted to the department of Traumatology and Orthopedics of our hospital from September 2018 to June 2020 were analyzed retrospectively, including 26 males and 12 females. The injury site included hand defects in 17 cases and foot defects in 21 cases. Soft tissue defect area was 1.3 cm×1.7 cm~12 cm×8 cm. All patients were repaired with free SCIP. The area of the skin flap was 1.6 cm×2.1 cm~15 cm×11 cm. Anti-infection, anticoagulation, anti-spasm, and heat preservation treatments were routinely given after the operation and regular follow-ups were performed. Results Thirty-eight cases of skin flaps were followed up for 8-14 months, with an average of 10.4 months; all skin flaps survived successfully. Two cases had vascular crisis after flap operation, and 1 case survived smoothly after activating blood circulation and antispasmodic treatment, one case relieved spontaneously after raising the affected limb. The remaining flap had good blood circulation, and the appearance and function recovered satisfactorily. Only linear scars remained in the donor area of the flap. Conclusions Under the concept of "swimming trunks supply area", free SCIP is designed to repair soft tissue defects of limbs, which integrates the function and appearance of the transplanted area, and also takes into account the location and aesthetic degree of the donor area, with few complications. As a better choice for repairing soft tissue defects in limbs, it is worthy of further clinical application.
