ABSTRACT:
An adjustable abduction shoe for treatment of metatarsus adductus includes an adjustable splint and heel wedge. The splint is disposed for abduction of the first metatarsal-phalangeal joint of the foot, and the wedge is disposed to prevent collapse of the midtarsal joint due to pressure. A specific embodiment is a rigid metal support bracket mounted to a shoe with one face along the exterior medial margin and transversing the vamp/quarter seam. A splint consisting of a rigid arm, preferably a spring steel plate, is secured to the posterior end of the bracket and extends along the interior medial margin of the shoe at least as far as the first metatarsal-phalangeal joint, i.e., adjacent the big toe. Means are provided for continuously adjusting the displacement of the unattached end of the rigid arm laterally at the first metatarsal-phalangeal joint. A convex shaped pad is mounted at the heel to form a varus wedge.
