Talonavicular arthrodesis.

Isolated talonavicular fusions have most commonly been performed for pes valgus deformity, rheumatoid arthritis, and post-traumatic arthritis. Recent reports have advocated its use for posterior tibial tendon dysfunction. The isolated fusion of the talonavicular joint is an effective procedure to reduce rearfoot biomechanical faults. This allows the procedure to not only address local pathology but general rearfoot deformities as well. Complications with the procedure are rare.
