摘要: Artificial joint prostheses are provided whose outer surfaces include a screw thread which is interrupted by porous-coated columns so as to produce an alternating pattern of threaded columns adjacent to porous-coated columns. The threaded columns provide initial mechanical fixation of the prosthesis to bone and the porous-coated columns provide long-term fixation through bone ingrowth.

摘要: A hip assembly and method are described in which a femoral head cap component secured to the femur with at least one screw is engaged with an acetabulum shell component affixed to the acetabulum with at least one screw, and a trochanteric osteotomy plate is secured to the femur with screws. The assembly further includes a psoas recess in the acetabulum shell for allowing freedom of movement of the illiopsoas tendon, countersunk cancellous screws for securing the components to the bones, and fins mounted on the femoral cap to prevent rotation in the bone.
