Tibiocalcaneal Arthrodesis

Abstract

A review of eight patients who underwent nine tibiocalcaneal arthrodeses was performed. The surgical indications were failed previous surgery, posttraumatic talar avascular necrosis, and rheumatoid arthritis. The average age at the time of operation was 54 years. The average time of follow-up was 40 months after the operation. Fusion was achieved in all nine feet, with an average time of fusion of 5 months. Results were excellent in three feet, good in four feet, fair in one foot, and poor in one foot. The average leg length discrepancy was 2 cm. The average position of fusion was 6° of valgus and 2° of plantarflexion. All patients stated that they had improvement of pain and function. Seven of the eight patients stated that they would have the procedure done again. Complications were local infection in two patients, malunion in two patients, wound slough in one patient, and a prominent fibula in one patient. Tibiocalcaneal arthrodesis should be reserved as a salvage procedure because it is technically difficult and has a significant risk of complications.
