ABSTRACT:
An orthopedic device suitable for controlling hip joints is provided which includes a first hinge means for flexion and extension of the hip and a second hinge means for abduction and adduction of the hip. The orthopedic hip hinge permits a shortening of the overall length of the hinge arm assembly during abduction of the hip and minimizes pistoning of the thigh attachment support. Also included with this invention are means for permitting free abduction of the orthopedic hinge within a specified range, while preventing any abduction of the hip. The disclosed device more closely approximates the actual motion of the femoral head in its socket, since the flexion hinge and the abduction hinge employ a common element, and are disposed in a ball-joint arrangement.
