A triple arthrodesis consists of the surgical fusion of the talocalcaneal (TC), talonavicular (TN), and calcaneocuboid (CC) joints in the foot. The primary goals of a triple arthrodesis are to relieve pain from arthritic, deformed, or unstable joints. Other important goals are the correction of deformity and creation of a stable, balanced plantigrade foot for ambulation.
Indications
Triple arthrodesis should be considered as a salvage procedure and only used after other treatment modalities have been exhausted. In conditions in which a lesser fusion or soft-tissue procedure will suffice, triple arthrodeses should not be used because of the potential long-term complications associated with it. The primary indications for the procedure are as follows:
- Valgus foot deformities that cannot be adequately braced
- Collapsing pes planovalgus deformity
- Advanced tibialis posterior tendon dysfunction
- Tarsal coalition
- Rheumatoid arthritis (RA)
- Degenerative arthritis (eg, DJD)
- Posttraumatic arthritis
- Chronic pain
- Varus foot deformities that cannot be adequately braced
- Cavus and cavovarus
- Talipes equinovarus
- Joint instability
- Neuromuscular disease
