Posterior interosseous artery perforator propeller flap for the repair of wrist and hand dorsal wounds.

Objective: This study aimed to evaluate the clinical efficacy of the posterior interosseous artery (PIA) perforator propeller flap for the repair of dorsal wrist and hand wounds. Methods: From October 2018 to October 2022, 12 patients with dorsal defects of the wrist ( Results: Twelve cases of skin flaps were successfully harvested, and the donor sites were directly sutured. Postoperatively, 11 flaps survived completely, while one case developed a wound infection that resolved with debridement and dressing changes. Patients were followed for 6-18 months (mean 12 months). Flap texture and appearance were satisfactory, with no significant swelling observed. Patient satisfaction reached 91.67%. At the final follow-up, DASH scores ranged from 2 to 15, with a mean of 9.2. Mild scar hyperplasia was observed at the donor site in two cases and at the flap margin in one case. Conclusion: For repairing soft tissue defects of the dorsal wrist, the posterior interosseous artery perforator flap provides a valuable and reliable clinical option due to its consistent vascular supply, preservation of major vessels, minimal surgical complexity, favorable aesthetic and tactile qualities, minimal donor-site trauma, and high flap survival rate.
