ABSTRACT Skin grafting may not always be possible for deep burns of the hand, due to possible exposure of tendons and bones. Although planning and use of free flaps is easier when used to cover broad defects, reconstruction of long and narrow defects is challenging. Here, we describe a patient with severe burns to his right hand who underwent reconstruction of his hand with a long narrow free radial forearm flap in a one-stage reconstruction.

ABSTRACT OBJECTIVES: Free microvascular tissue transfer can provide excess tissue in 1 stage for extensive injuries when locoregional flap options cannot be performed. Free flaps are an important reconstructive option in burn reconstruction whenever neurovascular and skeletal structures are exposed. This sophisticated technique needs surgical expertise and an understanding of burn physiology. Here, we have shared our experiences in burn reconstruction with free flaps. MATERIALS AND METHODS: Between 2017 and 2021, our center performed 26 free flap procedures in 20 burn patients. Fifteen flaps were performed in 12 patients at an early phase (first 21 days postinjury); 11 free flaps were performed in 8 patients for postburn contracture sequelae. Among these procedures, 60% were skin flaps (anterior lateral thigh, radial forearm, superficial circumflex iliac artery perforator flap, parascapular), 20% were musculocutaneous flaps (latissimus dorsi, vastus lateralis), 10% were fascia flaps (temporal fascia, serratus anterior), and 10% were pure muscle flaps (gracilis, latissimus dorsi). RESULTS: Two free flaps for early-phase reconstruction and 1 free flap for postburn contracture release were lost. Reasons for flap loss were venous congestion in 2 cases, with arterial occlusion due to hematoma formation in 1 case. All patients with flap loss had high-voltage electric burns. Debridement of the necrotic flaps was delayed until demarcation formation settled and until subflap granulation formation started. Skin grafts were performed after debridement of these flaps. All other flaps survived, with no recurrence of contractures or defects encountered in these patients. CONCLUSIONS: Although free flaps have changed the reconstructive ladder to a reconstructive elevator, performing these flaps have unique challenges in burn reconstruction, such as risk of thrombosis in those with electric burns, hemodynamic instabilities, and difficulties in patient positioning due to sedation. Meticulous care should be taken and the patient’s general condition should be well evaluated before free flap surgery.
