| titleOfInvention | Resurfacing cup for acetabulum hemiarthroplasty of the hip joint |
| abstract | The present invention disclosed resolves the main problems of bone-sparing hip resurfacing surgery by using only an acetabular component in which the femoral head articulates, being only shaved to a spherical shape and cleared of osteophytes that could impinge on the acetabulum and so restrict the range of motion. The inner surface of the resurfacing cup (10) is aspherical in shape creating an annular contact with the femoral head. The inner, articulating surface of the cup is ADLC or pyrolytic carbon coated to reduce friction and wear of the femoral head. The surgical approach is well developed with surgery time significantly reduced by avoiding the use of the femoral resurfacing component. The cup is preferably of the double-shell type for cementless fixation, but it can also be made as a single shell for cementless or cemented fixation. Should a revision surgery due to wear of the femoral head become necessary, the cup can be retained and combined with a dual mobility femoral component. |
