INTRODUCTION: Lower extremity defects may account for 14.6% of the approximately 117 million visits to emergency departments in the U. S. in 2007. In this article, we present a reconstruction of a traumatic plantar foot defect with a medial triceps brachii (MTB) free flap. CLINICAL CASE: A 53-year-old man sustained an accidental gunshot wound to the right foot. The patient was admitted after the failure of a sural flap procedure performed in another hospital. He presented with a soft-tissue defect with calcaneal exposition and osteomyelitis. The defect was reconstructed with a MTB free flap anastomosed to his dorsalis pedis vessels. RESULTS: Flap raising time was 52 min. There were no intraoperative complications. The total flap surface was 38.5 cm². The pedicle length was 3 cm. The diameters of the artery and vein of the flap pedicle were 1.1 mm and 1.4 mm, respectively. Ischemia time was 28 min. His donor site healed uneventfully without any morbidity, and the scar was well concealed. The flaps survived and there was no partial flap necrosis. A split-thickness skin graft was performed 12 days postoperatively. Two months later, he had a completely healed wound with no contour abnormality. The total follow-up was 24 months. The patient was able to walk normally. CONCLUSION: MTB free flap appears to be an excellent option for plantar foot defects in patients with preserved vascularization of the foot. Due to the anatomical shape of the flap, the position of its pedicle, and the moldability of the muscle, we predict that the use of the MTB free flap will grow and develop rapidly for reconstruction of ankle and foot defects.
