Bony reconstruction during tibiotalocalcaneal arthrodesis in the face of large bony defects remains a challenging procedure. These large bony defects could be caused by avascular necrosis of the talus, trauma, failed total ankle replacement, osteomyelitis, Charcot arthropathy, tumours of the talar body or failed reconstructive surgery (1). Previous studies have shown that treating body defects of the talus with tibiocalcaneal fusion could result in significant limb length discrepancy, ankle instability and chronic pain (2). The use of bulk femoral head allograft in tibiotalocalcaneal fusion can reconstruct the height of the ankle and at the same time provide a good bed for fusion to occur (3). We report a case of traumatic bone loss of the talus in which a tibiotalocalcaneal arthrodesis was done using bulk femoral head allograft.
