The use of intramedullary nails in tibiotalocalcaneal arthrodesis

Tibiotalocalcaneal arthrodesis is a salvage procedure undertaken for hindfoot problems that affect both the ankle and subtalar joints (eg, two-joint arthritis, severe acute trauma, osteonecrosis of the talus, severe malalignment deformities, significant hindfoot bone loss). Methods of achieving fusion include Steinmann pins, screws, plates, external fixators, and retrograde intramedullary nailing. Retrograde intramedullary nailing provides a load-sharing fixation device with superior biomechanical properties and is an excellent choice for use in tibiotalocalcaneal arthrodesis. This technique can be performed through relatively small incisions. In addition, recent design modifications include the availability of dynamization and the choice of curved or straight nails. Contraindications to the technique include the presence of infection, severe vascular disease, and severe malalignment of the tibia.
