ABSTRACT:
A composite orthosis immobilizes an injured joint such as the ankle, wrist, elbow or knee joint. Generally, the orthosis has lateral and medial support members extending along opposite sides of a limb adjacent the injured joint, a brace secured to the limb on the opposite side of the injured joint, and pivot means hinging the lateral and medial support members to the brace. In one form of the invention, an ankle brace is provided by lateral and medial support members extending along lateral and medial sides of the lower leg above the ankle, a shell which fits around the foot, and a separate pivot for hinging each support member to the shell in the vicinity of the ankle axis of rotation. With the user's foot in the shell and the support members extending alongside the lateral and medial sides of the lower leg, a bandage is wrapped tightly around the support members above the ankle joint for tightly securing the lateral support members to the sides of the lower leg above the ankle joint. This immobilizes the ankle joint against lateral and medial movement and provides limited resistance against torsion while allowing forward and backward rotation about the ankle joint.
