Abstract
A hip replacement system including a socket having generally hemispherical cavity therein, a ball member cantably affixed within the socket, a stem affixed to the ball member and extending outwardly therefrom, and a lubricant located within a channel formed interior of the stem. The exterior surface of the ball member has at least one opening therein communicating with channel of the stem. The lubricant fills a space between the exterior surface of the ball member and the inner wall of the cavity of the socket. The lubricant is compressed body fat. An inlet is connected to the channel so as to extend outwardly of the stem for allowing the introduction of the lubricant into the channel.
Claims17
A hip replacement system comprising:
- a socket having a generally hemispherical cavity therein;
- a ball member cantably affixed within said socket, said ball member having an exterior surface positioned within said generally hemispherical cavity of said socket, said exterior surface having at least one opening therein communicating with an interior of said ball member;
- a stem affixed to said ball member and extending outwardly therefrom, said stem having a channel therein in communication with said opening on said ball member;
- and
- a lubricant located within said channel of said stem, said lubricant being body fat.
A hip replacement system comprising:
- a socket having a generally hemispherical cavity therein;
- a ball member cantably affixed within said socket, said ball member having an exterior surface positioned within said generally hemispherical cavity of said socket, said exterior surface having at least one opening therein communicating with an interior of said ball member;
- a stem affixed to said ball member and extending outwardly therefrom, said stem having a channel therein in communication with said opening on said ball member;
- and
- a lubricant located within said channel of said stem, said socket comprising:
- a metallic exterior body having an interior surface;
- and
- a polymeric lining affixed to said interior surface of said metallic exterior body, said ball member juxtaposed against said polymeric lining;
- and
- a sealing means affixed to an end of said socket for retaining said lubricant in a space between said exterior surface of said ball member and said interior surface of said socket, said sealing means being an annular gasket having an inner edge juxtaposed against said exterior surface of said ball member.
A joint replacement system comprising:
- a socket having a polymeric lining;
- a ball member cantably affixed within said socket, said ball member having an exterior surface within said socket, said exterior surface having an opening thereon;
- a stem affixed to said ball member and extending outwardly therefrom, said stem having a channel therein in communication with said opening on said ball member;
- a lubricant received within said channel of said stem and extending into a space between said exterior surface of said socket and said polymeric lining of said socket;
- and
- an inlet means connected to said channel and extending outwardly of said stem, said inlet means for allowing said lubricant to be introduced into said channel.
