<p>COD 34 LOAD-STABILIZING PROSTHETIC JOINT AND COMPONENTS THEREOF A load-stabilizing 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 and a shank terminating in a headed member. A second component is adapted to be associated with a second bone adjacent the first bone and has a terminal portion with rigid wall means defining an open ended socket. A third component, for connecting the first and second components, has an internal cavity and passage means communicating therewith. The third component is su flexible to permit the headed member to be passed through the passage means into the cavity to connect the first and third components. The rigid wall means of the second component embraces the third component providing support therefor, and prevents the headed member from passing outwardly of the COD 34 passage means in use. Included on the third component is an arcuate bearing surface mating with the arcuate bearing surface of the first component, the bearing surfaces cooperating to carry the loading forces of and stabilize the joint in use. A prosthetic component for use in a joint includes a stem for insertion in the intramedullary canal of a bone, and an arcuate bearing surface at one end thereof. A shank terminating in a headed member is included to provide pivotal attachment of the component in the joint. A connecting component for interconnecting two components of a prosthetic joint together comprises a substantially cylindrically shaped flexible body having a convex peripheral surface and two flat sides. A cavity is located internal the body, and passage means from the peripheral surface. communicates with the internal cavity for accommodating means to connect one of the joint components thereto. Means on the flat sides is provided to engage the second of the joint components whereby the connecting component interconnects the first and second joint components.</p> |
