[Management of post-traumatic tibiotalar osteoarthritis following a failed osteosynthesis : retrograde plantar nailing].

Tibiotalar osteoarthritis, uncommon and often of post-traumatic origin, leads to functional limitations, chronic pain and significantly impairs the quality of life. Both tibiotalar arthrodesis and arthroplasty have been proven effective. Tibiotalocalcaneal (TTC) arthrodesis is generally reserved for ankle osteoarthritis associated with severe degeneration of the subtalar joint and hindfoot. Nevertheless, new data showed good outcomes regardless of the subtalar joint state. We present the clinical case of an 86-year-old female patient with severe tibiotalar osteoarthritis after a failed osteosynthesis. She underwent successfully TTC arthrodesis using a retrograde intramedullary nail.
