Reconstruction of Bilateral Hindfoot Open Fracture Using the Femoral Head Allograft: A Three-Year Follow-Up Case Report.

This case report presents a three-year follow-up of a young male with bilateral hindfoot fractures due to a high-energy road traffic accident, resulting in a comminuted open calcaneal fracture on the left and an open fracture-dislocation of the right talus. Staged reconstruction was performed, including initial debridement, temporary cement spacers, and subsequent fixation with femoral head allografts (FHAs). The right foot underwent a tibiotalocalcaneal (TTC) fusion, and the left foot received a double arthrodesis. Follow-up imaging confirmed allograft integration and complete fusion. At three years, the patient had a stable, plantigrade foot and satisfactory function for daily activities. This case demonstrates the successful use of FHAs for complex hindfoot reconstructions, preserving limb length and functionality.
