Congenital Vertical Talus.

Congenital vertical talus represents a congenital structural foot deformity characterized by the classical rocker bottom deformity. The main feature is dislocation of the talonavicular joint along with contractures of the dorsolateral tendons of the foot and tendo Achilles. In the past treatment consisted of 2- or single-stage more or less extensive soft tissue releases including reduction of the talonavicular joint following casting in the first phase. Nowadays all feet are treated by serial casting, closed or miniopen talonavicular joint reduction, and percutaneous achillotenotomy. Functional results of the miniinvasive method are superior to those of the former more extensive surgical releases.
