Background: The first dorsal metacarpal artery (FDMA) flap is used mainly for reconstruction of thumb defects. We share our experience of this flap for various defects of thumb and also its use to cover other defects. Materials and Methods: Case records of 15 patients with FDMA flap between October 2015 and February 2018 at our center were analyzed retrospectively. Data were analyzed for etiology, associated comorbidities, interval between injury and operation, site of defect, harvesting technique, and inclusion of dorsal interossei muscle cuff, complications, donor-site morbidities, and postoperative sensory recovery. Results: Of 15 patients, 13 were male and 2 were female. Eleven patients had a posttraumatic defect, 2 had post-electric burn defect, 1 had a firecracker injury, and 1 had a post snakebite defect. Of 15 patients, 12 patients had thumb defects, 1 patient with defect of first web space, 1 on volar aspect of palm, and 1 on the dorsum of hand over the head of third metacarpal. All patients showed protective sensations and 6 patients with 12-month follow-up showed minimum of 9 mm of two-point discrimination with no donor-site morbidity. Conclusions: The FDMA flap has a constant anatomy, easy dissection, and shows good functional and esthetic results. FDMA flap is the first treatment of choice for defects of the thumb, but it can be used for selected small defects of hand due to its wide arc of rotation.
