Abstract
Abstract An adjustable leg brace for rapid attachment to the leg of an individual, as desired. The lowermost member of the brace is secured to the heel of the user''s shoe. Also secured to this member is a horizontal adjustment member to allow for horizontal adjustment of the lower angle upright. The upper angle upright is vertically secured to the lower upright, and between the two, the lowermost member is adjusted for the specific vertical location of the user''s ankle joint. A removable Tee-strap bar provides an anchor for an ankle support strap. Calf and thigh uprights may also be individually adjusted in the same manner as the ankle uprights to accommodate the vertical variation of the user''s leg. Adjustable cuffs are secured to the calf and thigh at appropriate locations with means to accommodate the circumference of the particular user. The brace may be used either to support the whole leg or just the lower leg, alone.
