Abstract
Background: Coverage of extensive defects of the thumb, with exposure of tendon and/or bone, presents challenging reconstructive problems. Aim: The aim of this study is to evaluate the versatility, applicability, and patient satisfaction with the first dorsal metacarpal artery flap for thumb reconstruction. Methods: This prospective case series study was conducted over approximately four years (June 2017–September 2022) in the Plastic Surgery Department at Rizgary Teaching Hospital in Erbil. Twelve patients with complex soft tissue thumb defects exposing vital structures were included and treated with first dorsal metacarpal artery island flaps. Results: Twelve patients participated in the study. Their mean age (SD) was 33.7 (14) years, with an age range of 9-57 years. The majority (75%) were males. Nine flaps survived, two cases experienced partial necrosis, and one case resulted in total loss. Overall, sensory function of the flap area was satisfactory for 8 patients (66.6%) and unsatisfactory for 4 cases (33.3%). Conclusion: The first dorsal metacarpal perforator artery flap is versatile, with a reliable vascular supply, providing satisfactory functional and aesthetic restoration. This makes it an appealing choice for addressing various soft tissue defects.
