ABSTRACT:
An ankle orthotic of substantially resilient material is provided comprised of a heel portion, an ankle support portion, and a talofibular support portion. The heel portion is substantially rigid and form fitting, preventing excessive inversion forces from being generated at the subtalar joint. The ankle support portion is relatively resilient and extends vertically from the heel portion, with the medial aspect extending higher than the lateral aspect. This form results in creating a three-point pressure system, which resists inversion forces from displacing the ankle mortise. The proximal end of the ankle support portion is enclosed via a fastening strap to customize fit. The talofibular support portion extends laterally and distally from the heel portion and reinforces the relatively vulnerable anterior talofibular ligament, providing stabilization and decreasing injury to the lateral ligamentous complex of the ankle. A flange or similar device may be present on the heel and/or forefoot of the orthotic allowing incorporation into the body or last of a shoe. This exoskeletal design would allow maximal structural stability by decreasing shear forces which might form between the shoe/orthotic interface.
