Abstract: An orthopedic walking boot promotes rapid healing of diabetic foot ulcerations by lowering the maximum peak pressure imposed upon the foot. The walker has a hard unyielding shell which is designed for walking. The shell closely and rigidly supports a mid-sole in a foot-shaped bed. The mid-sole has a foot-shaped cavity with rounded sides adapted to form resilient support for the heel, arch and sides of a foot in addition to the bottom of a foot. A conformable inner-sole is adapted to fit over the foot-shaped cavity in the mid-sole and be compressed in response to foot pressure between the sides and bottom of the foot and the sides and bottom of the foot-shaped cavity in the mid-sole thereby compensating for small differences between the shape of the foot and the shape of the cavity.

Abstract: A dynamically shiftable knee brace is used to counteract anterior tibial displacement caused during leg extension by the quadriceps muscle when the anterior cruciate ligament is missing or damaged. The brace includes pairs of rigid thigh and calf support members which extend along and are strapped to thigh and calf portions of the leg, the support member pairs being pivotally connected at their inner ends to one another by a pair of specially designed hinges positioned on opposited sides of the knee. As the leg is extended from a flexed position toward its fully straightened position the hinges cause a relative anterior-posterior shift between the support member pairs in a manner creating a shear force across the knee which is opposite that generated by the quadriceps muscle.

Abstract: A passive motion exerciser for simultaneously flexing the hip and knee joints of a human leg has a base portion with an inclined guide member positionable parallel to a line extending through the ankle and hip joints of the leg, a reversible motor-driven drive member movable upwardly and downwardly along the inclined guide member, and an elongated leg support frame structure securable to the leg and longitudinally adjustable to fit legs of varying lengths. The support frame structure has a first end portion positionable adjacent the ankle joint, a second end portion positionable between the knee and hip joint, and a pivoted intermediate portion positionable adjacent the knee joint. A connecting member is attached to the guide member for movement therealong parallel to the drive member and is connected to the first outer end portion of the support frame structure. The second outer end portion of the support frame structure is pivotally interconnected to the drive member by a cam-driven linkage structure.
