A cavovarus foot is characterized by exacerbated medial longitudinal arch (cavus), hindfoot varus, plantar flexed first ray, forefoot pronation (apparent supination), forefoot adduction, and claw toe deformities. It can be broadly divided as flexible and rigid and further classified based on the neurological and non-neurological causes. Diabetes associated peripheral neuropathy complicates individual bony deformities associated with cavovarus foot with early callus which can breakdown to ulceration rapidly. Based on the disease progression in neurological and non-neurological causes of cavovarus feet in patients with diabetic neuropathy, 3 stages of the disease and its management is described.
