A fracture brace for a leg has an interior jacket for placement over the front of a leg, and for wrapping around the medial and lateral sides of a leg outside of a posterior shell. The posterior shell fits over the calf and the lateral and medial sides of the leg. Straps anchored on the shell unite the jacket and the shell to form an enveloping case for the leg that permits transmission of bearing pressures through the fleshy part of the leg, the tibia, and the brace. An interior pad integral with the jacket extends along the anterior of a leg from the proximal tibia to the distal tibia. There the pad wraps to the sides to provide padding for the bony prominences of the medial and lateral malleolus. A footplate connects to the jacket through a pair of uprights, each of which attaches to the footplate through a pivot and to the jacket by hook and pile fasteners. The attachment to the jacket permits adjustment of the footplate with respect to the jacket and therefore the foot with respect to the tibia: (1) in translation generally along the axis of the tibia, (2) in translation generally along an axis through the length of the foot, (3) in rotation generally around the axis of the tibia, and (4) in rotation generally about the axis through the length of the foot. The footplate can rotate about axes generally medial-to-lateral and through pivots connecting the footplate and the uprights.

An improved prefabricated fracture orthosis for a leg comprising: (a) an anterior jacket having an interior shape corresponding to the shape of a leg from about the ankle to the knee, an open posterior, and flexibility about vertical axes to contract and expand about a leg to conform to the leg; (b) a posterior shell for receipt in the jacket and having a closed posterior side, a shape generally conforming to the shape of a calf from about the ankle to the top of the calf, and flexibility about vertical axes to expand and contract into contact with the calf to conform to the calf; (c) means to secure the shell to the jacket while encasing a patient\s leg to permit loading of the soft tissue of the leg and the tibia and fibula without unacceptable angulation or rotation; (d) a footplate; (e) a lateral and a medial upright each pivotally attached to the footplate to permit rotation of the footplate about generally horizontal, pivotal axes extending from the medial side of a patient\s leg to the lateral side; and (f) means for attaching the medial and lateral uprights to the jacket with each upright having an infinite number of positions within predetermined ranges: (i) in vertical translation with respect to the jacket, (ii) in anterior-to-posterior translation with respect to the jacket, (iii) in rotation about axes generally normal to the longitudinal axis of the jacket and corresponding to the axis of a patient\s foot, and (iv) in rotation about longitudinal axes of the jacket.
