Case report of substantial reconstruction of second ray segment by osteo-tendo-cutaneous pedicled radial forearm flap.

Introduction and importance: The hand is one of the most vital organ that the surgeon aims to preserve its function and natural appearance. Gunshot injuries are common, especially in a war zone, and unfortunately, they create complex wounds that are hard to reconstruct and infection is very common. In this article, we report rebuilding segment of index finger with a pedicled osteo-tendo-cutaneous radial forearm flap. Case presentation: A 50-year-old man-African with no past medical comorbidities, sustained trauma to his left index finger by high-velocity injury that led to composite tissue loss including metacarpal and proximal phalanx. After applying the initial irrigation and dressing to the wound, his hand was supported by a volar cast then he was referred to the hospital. The hand was examined at the operation room and the index finger was found to be hanged with a medial skin pedicle with necrotic and exposed bone and tendon. He underwent a session of debridement followed by reconstruction using a pedicled osteo-cutaneous radial forearm flap accompanied with metacarpophalangeal joint arthrodesis. Clinical discussion: A significant number of war-related hand injuries resulted in amputations because there were not enough facilities or doctors. While they are alternatives to free flap, abdominal and regional flaps won't yield the same outcomes. The second ray of the hand is reshaped using a radial flap, producing an acceptable result. Conclusion: The Radial forearm flap was used to reconstruct segment of index finger and fulfill our requirements, which include bone, tendon, and skin cover. Additionally, this is a simple and single stage procedure and micro-surgical equipment is not necessary.
