Abstract
A controlled motion ankle fracture walker includes a foot supporting rocker to which the foot of a patient is releasably secured, and a leg support wrapped around the patient's lower leg above the ankle joint. The foot support includes a rigid shell with a curved bottom forming a rocker for rolling contact with the ground to provide a rocking heel to toe motion of the patient's foot during weight bearing. Rigid lateral and medial uprights are rigidly affixed alongside the leg support, and adjustable double action ankle joints pivotly interconnect the bottoms of the uprights with the rigid support arms on the lateral and medial sides of the foot supporting shell. The ankle joints permit adjustable range of motion of the uprights in dorsiflexion or plantar flexion. The walker allows the patient to apply weight to the ankle joint during a normal walking gait while the ankle joint can be flexed through a controlled degree of dorsiflexion, plantar flexion, or both, by the front to rear settings of the adjustable double action ankle joints.
