Reconstruction of extreme post-burn scar contracture of the ankle using a thoracodorsal artery perforator flap: a case report

Post-burn scar contracture associated with deep second-degree or higher burns in the joint area can lead to joint immobility and may cause chronic ulcers, substantially impacting patients’ quality of life. Surgical intervention is necessary, with local flaps or skin grafts being the first option. In extreme cases, free flap transfer may be required to address large defects that occur after contracture release. This study presents a successful case of reconstruction using free flap transfer in a patient with severe post-burn scar contracture, which resulted in a club-like deformed ankle with a nonfunctional joint. Despite the extreme deformity and nonfunctioning joint, we utilized a thoracodorsal artery perforator flap to stably cover the newly fused joint in a neutral position. After reconstruction, the patient was able to wear shoes and ambulate. This case highlights the potential of free flap transfer even in the most challenging situations where joint function is severely compromised.
