Abstract：
Total calcaneus and talus loss in the hindfoot is an unusual but severe condition encountered in clinical settings. This condition affects lower-extremity function and poses a significant challenge to limb salvage. We present a case of a 43-year-old man with total calcaneus and talus loss in the right foot treated by Ilizarov technique. A staged treatment protocol was planned to reconstruct and optimize the heel for weightbearing and walking. During the 15-month postoperative follow-up, the patient reported no significant discomfort in the targeted foot and regained satisfactory function, including shoe wearing, walking, driving, and climbing stairs. The American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale score was 71, which was an improvement from a preoperative score of 40. This case is the first reported on the functional reconstruction by Ilizarov technique of hindfoot with total calcaneus and talus loss. This treatment protocol provides an effective approach to reconstructing the hindfoot with massive bone loss, although the long-term outcome remains unknown.
