Abstract

Background: Soft tissue defects of the fingers are increasingly common, often with exposed tendons, bones, or joints requiring early coverage. The dorsal metacarpal artery perforator flap provides advantages for reconstruction. Subject and Methods: A cross-sectional descriptive study was conducted on 39 patients with 41 soft tissue defects of the fingers reconstructed using dorsal metacarpal artery perforator flaps at the Department of Maxillofacial, Plastic, and Aesthetic Surgery, Viet Duc Friendship Hospital, between January 2020 and March 2025. Parameters analyzed included clinical features, defect characteristics, flap type and size, complications, and postoperative outcomes at 1 and 3 months. Results: Males 69.2%, most common age 40–59 years (46.2%). Occupational injuries predominated (89.7%). Thumb most often injured (43.9%), right hand more frequent (63.4%). Associated injuries: bone 41.5%, joint 36.6%, tendon 12.2%. Reverse-flow flaps used in 61.0%. Mean size 11.77 ± 5.44 cm². At 1 month: 92.7% survived, 2.4% partial necrosis, 2.4% extensive necrosis, 2.4% failure. At 3 months: 85.0% good, 15.0% fair, no failures. Conclusion: The dorsal metacarpal artery perforator flap is a safe, effective, and practical option for finger soft tissue reconstruction, especially in complex cases with exposed tendons, bones, or joints.
