An evaluation for compensated anterior cavus

Anterior cavus is a multiplane structural deformity that can originate from different areas within the foot. Differentiation of these areas is a necessary examination in order to determine the effect of proper treatment. A depressed fourth and fifth ray or lateral column is a major deformity in anterior cavus. The lateral column deformity is a pronatory force that causes a premature medial shift of weight. The premature shift can cause a breakdown of the medial column of the foot. We have developed an examination of the compensated anterior cavus deformity that enables the practitioner to isolate better the pronatory forces within the foot.
