Treatment of ankle instability with an associated cavus deformity.

This article reviews the role of cavus in foot and ankle injury and summarizes the current surgical and nonsurgical treatments. Recognition of foot position is crucial in the management of ankle instability associated with cavovarus. Correcting foot alignment with orthoses or surgery improves the mechanics of the ankle, reducing the risk of instability and potentially delaying the onset of posttraumatic ankle arthritis. Progressive steps in the correction alignment are described, with technical tips and strategies for dealing with chronic instability.
