Abstract: A fracture brace for leg and ankle treatment includes a shoe having a support surface for supporting the sole of a patient's foot, side walls extending generally perpendicularly to the support surface and an outer sole member. The side walls of the shoe include a receptacle having an outer wall spaced apart from the side wall of the shoe and end walls disposed generally perpendicularly to the shoe side wall and the outer wall. The side walls of the shoe include a spring disposed within the receptacle. The brace further includes side plates each having first and second ends for selective interconnection to the receptacle. The second ends of the side plates are adapted to be received and locked between the spring and the outer wall of the receptacle to prevent removal therefrom.
