Adult Cavovarus Foot

Abstract

Pes cavovarus is defined by the clinical finding of an elevated medial longitudinal arch in association with a varus hindfoot, and is commonly associated with clawing of the hallux and lesser toes. Typically, the cavovarus foot is the result of an abnormal balance of the muscle forces about the foot, often from a neuromuscular disorder. Weakness of the intrinsic muscles of the foot and/or foot dorsiflexors causes an initial flexible deformity, which becomes rigid over time. Treatment is guided by the location and rigidity of the deformity, with the goal of creating a plantigrade, pain-free foot for ambulation. More severe or progressive deformities may require surgical management. The potential combinations of soft-tissue and bony procedures are numerous, and selection of the appropriate procedures is based on the particular clinical features of the patient.
