Adjustable abduction device for treatment of metatarsus adductus

摘要

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.
