Abstract
Unlike the prior art crutch that in essence extends the shoulder to the ground to bear the weight of the injured person when walking, the novel walking device of the invention includes an upright staff that extends the pelvis to the ground on the side of an injury. Upper and lower receiving members for receiving and securing to the thigh and calf of an injured leg are attached to the staff and securing means secure the thigh and calf to said receiving means. The injured limb bears the load in compression rather than in shear.
