Tibiotalocalcaneal (TTC) arthrodesis is a surgical procedure that fuses the ankle and subtalar joints, which includes the tibia, talus, and calcaneus. This procedure is generally reserved for patients with severe deformities, arthritis, or instability in the ankle and hindfoot. Femoral head allografts can be used in this procedure to fill large bone defects or gaps, provide structural support, and facilitate arthrodesis.

Specification Clinical Support

This study presents two cases where Tibiotalocalcaneal (TTC) arthrodesis, using a bulk femoral head allograft and a novel pseudoelastic intramedullary nail, successfully salvaged failed total ankle replacements. These cases provide initial evidence that this approach is an effective treatment for failed total ankle replacements.
This study reviewed 24 Tibiotalocalcaneal (TTC) arthrodesis procedures with femoral head allografts. It suggested that the use of femoral head allograft with TTC arthrodesis resulted in improved functional scores, sustained radiographic outcomes, and complete radiographic union in 63% of patients and 75% of all joints, suggesting its potential as a beneficial treatment for complex hindfoot osseous deficits.
