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 a one-piece, unitary, resilient element formed of polyurethane, having a generally cup-shaped configuration and defining an articulating surface for articulating engagement with a femoral head and a mounting surface for mounting engagement with a machined natural acetabulum, said mounting surface comprising a mounting surface portion configured for snap fit engagement with a corresponding machined natural acetabulum surface portion defined by said machined natural acetabulum.  
     
     
         2 . A hip joint prosthesis according to  claim 1  and wherein said articulating surface and said mounting surfaces of rotation and lie generally parallel to each other.  
     
     
         3 . A hip joint prosthesis according to  claim 1  and wherein said mounting surface portion comprises at least one protrusion.  
     
     
         4 . A hip joint prosthesis according to  claim 1  and wherein said at least one protrusion comprises a generally peripherally extending protrusion.  
     
     
         5 . A hip joint prosthesis according to  claim 1  and wherein said mounting surface portion defines an undercut.  
     
     
         6 . A hip joint prosthesis according to  claim 2  and wherein said mounting surface portion comprises at least one protrusion.  
     
     
         7 . A hip joint prosthesis according to  claim 2  and wherein said at least one protrusion comprises a generally peripherally extending protrusion.  
     
     
         8 . A hip joint prosthesis according to  claim 2  and wherein said mounting surface portion defines an undercut.  
     
     
         9 . A hip joint prosthesis according to  claim 3  and wherein said at least one protrusion comprises a generally peripherally extending protrusion.  
     
     
         10 . A hip joint prosthesis according to  claim 3  and wherein said at least one protrusion defines an undercut.
