Abstract
A preventive brace for supporting anatomical joints, such as the ankle joint, includes a semi-rigid leg-supporting shell conforming to the shape of the lower leg above the ankle joint, a semi-rigid foot-supporting shell conforming to the shape of the foot, and lateral and medial circular hinges rotatably securing the lateral and medial sides of the leg-supporting shell to the foot-supporting shell. The circular hinges are formed by relatively large area wall portions of the shells which overlie one another in the vicinity of the ankle bones (lateral and medial melleoli) projecting from the lateral and medial sides of the ankle. The overlying faces of the walls are rotatably interconnected along a circularly curved axis spaced outwardly from the ankle bone. In one embodiment, the circular hinge is centered generally on the ankle bone and traverses a circular path spaced a substantial distance outwardly from the ankle bone. The circular hinge allows the leg-supporting shell to rotate freely about the foot-supporting shell. A large open central region within each circular hinge prevents the supportive portions of the shell walls from applying pressure to the ankle bones. When the brace is secured to the ankle region, the large supportive walls of the shell provide substantial orthopedic support to the regions entirely around the lateral and medial melleoli. The circular hinge allows good freedom of movement of the brace while maintaining comfort by avoiding application of pressure to the ankle bones.
