clubfoot [ME, clubbe + AS, fot] , a congenital deformity of the foot, sometimes resulting from intrauterine constriction and characterized by unilateral or bilateral deviation of the metatarsal bones of the forefoot. Ninety-five percent of clubfoot deformities are equinovarus, characterized by medial deviation and plantar flexion of the forefoot, but a few are calcaneovalgus, or calcaneovarus, characterized by lateral deviation and dorsiflexion either outward from or inward toward the midline of the body. Treatment depends on the extent and rigidity of the deformity. Splints and casts in infancy may produce complete correction. Surgery in several steps may be necessary to achieve normal function. See also Denis Browne splint, talipes.
