Abstract

A joint prosthesis comprising at least a first and a second load carrying member, the first load carrying member being substantially more shock absorbing and resilient than the second load carrying member.

Claims

exact text as granted — not AI-modified
1 . A hip joint prosthesis comprising an artificial femoral head which is adapted to articulate with both a femur and an acetabulum.  
     
     
         2 . A hip joint prosthesis according to  claim 1  and wherein said artificial femoral head is constructed of a relatively rigid material, compatible with human tissue.  
     
     
         3 . A hip joint prosthesis according to  claim 1  and wherein said artificial femoral head is constructed of a material which is shock absorbing.  
     
     
         4 . A hip joint prosthesis according to  claim 1  and wherein said artificial femoral head is constructed of a material which is resilient.  
     
     
         5 . A hip joint prosthesis according to  claim 1  and wherein said artificial femoral head is generally spherical.  
     
     
         6 . A hip joint prosthesis according to  claim 1  and wherein said artificial femoral head is formed with a hollow core.  
     
     
         7 . A hip joint prosthesis according to  claim 1  and also comprising an artificial acetabulum having an articulating surface with which said artificial femoral head articulates.  
     
     
         8 . A hip joint prosthesis according to  claim 1  and also comprising an artificial femoral socket having an articulating surface with which said artificial femoral head articulates, said artificial femoral socket being adapted for fixed attachment to said femur.  
     
     
         9 . A hip joint prosthesis according to  claim 2  and also comprising an artificial femoral socket having an articulating surface with which said artificial femoral head articulates, said artificial femoral socket being adapted for fixed attachment to said femur.  
     
     
         10 . A hip joint prosthesis according to  claim 1  and wherein said artificial femoral head is formed with fluid passages adapted to allow flow therethrough of synovial fluid.  
     
     
         11 . A joint prosthesis comprising an artificial ball element which is adapted to articulate with both first and second ball sockets defined by a joint.  
     
     
         12 . A joint prosthesis according to  claim 11  and wherein said artificial ball element is constructed of a relatively rigid material, compatible with human tissue.  
     
     
         13 . A joint prosthesis according to  claim 11  and wherein said artificial ball element is constructed of a material which is shock absorbing.  
     
     
         14 . A joint prosthesis according to  claim 11  and wherein said artificial ball element is constructed of a material which is resilient.  
     
     
         15 . A joint prosthesis according to  claim 11  and wherein said artificial ball element is generally spherical.  
     
     
         16 . A joint prosthesis according to  claim 11  and wherein said artificial ball element is formed with a hollow core.  
     
     
         17 . A joint prosthesis according to  claim 11  and also comprising an artificial ball socket having an articulating surface with which said artificial ball element articulates.  
     
     
         18 . A joint prosthesis according to  claim 11  and also comprising an artificial ball element socket having an articulating surface with which said artificial ball element articulates, said artificial ball element socket being adapted for fixed attachment to a bone.  
     
     
         19 . A joint prosthesis according to  claim 12  and also comprising an artificial ball element socket having an articulating surface with which said artificial ball element articulates, said artificial ball socket being adapted for fixed attachment to a bone.  
     
     
         20 . A joint prosthesis according to claim II and wherein said artificial ball element is formed with fluid passages adapted to allow flow therethrough of synovial fluid.
