Triple arthrodesis is used for severe hindfoot deformities in which condition?

• A. Charcot joint due to trauma
• B. Charcot-Marie-Tooth disease
• C. Clubfoot deformity
• D. Rheumatoid arthritis

Answer: (B)

Triple arthrodesis is a salvage procedure used when the hindfoot joints are irreversibly destroyed by neuropathic Charcot changes and a rigid, painful deformity persists. In Charcot neuroarthropathy, which can occur in hereditary neuropathies such as Charcot‑Marie‑Tooth disease, the subtalar, talonavicular, and calcaneocuboid joints collapse and lose stability. Fusing these joints across the hindfoot converts it into a single stable column, relieves pain, and allows weight bearing in a plantigrade position. This makes it the best option for severe hindfoot deformity in this neuropathic setting.
