[Posttraumatic arthritis in the hind foot]

Posttraumatic arthritis of the joint components of the hind foot is typically linked with hind foot deformity and involvement of the neighbouring joint. The principal goals of any hind foot reconstruction are to achieve a quasi-anatomical reconstruction of the geometry and a stable and plantigrade foot position as a prerequisite for acceptable gait function, and an overall satisfactory result for the patient. Profound knowledge of the functions of the ankle-hind foot complex is the basis for the development of a valid therapeutic strategy. Any surgical reconstruction has to consider previous interventions, local soft tissue conditions, neurovascular status, and the components of deformity and degree of arthritic destruction at the corresponding joint levels. In general, an arthrodesis of any hind foot joint, as a key element in hind foot reconstruction, will be successful if correction of the underlying deformity is also adequately addressed.
