title: Posterior tibial tendon insufficiency. Isolated fusion of the talonavicular joint.
abstract: In selected patients, fusion of the talonavicular joint can be an effective treatment of adult flatfoot deformity. Restriction of motion and altered hindfoot mechanics, however, are a consequence of talonavicular fusion and can lead to accelerated arthrosis of adjacent joints. In patients with severe long-standing deformity, medial displacement calcaneal osteotomy may be a necessary adjunct to talonavicular fusion for adequate correction of heel valgus.
