Ankle disarticulation amputation in patients with peripheral vascular disease is sometimes complicated by delayed healing or residual limb volume fluctuation. This change in shape and contour presents several challenges to the prosthetist charged with producing a static prosthesis that must meet the demands of a constantly changing residual limb.This article describes a method of producing a preparatory ankle disarticulation prosthesis that can be quickly and inexpensively fabricated, and can adapt to changing residual limb size and shape.
