ABSTRACT:
A prosthetic joint is comprised of three basic components. A first component is adapted to be associated with a first bone and has an arcuate bearing surface at one end thereof. The first component is constructed such that it may pivot on its bearing surface. A second component is adapted to be associated with a second bone adjacent to the first bone. The second component has a terminal portion at one end facing toward the bearing surface of the first component and has rigid walls defining an open-ended socket. The walls of the second component are connected to the first component in a manner to allow pivoting of the first component with respect to the second component. A third component has an arcuate bearing surface mating with the arcuate bearing surface on the first component. The third component is located in the open-ended socket with its walls embracing the same so that the mating bearing surfaces cooperate to carry the loading forces of the joint in use.
