A prosthetic constraining device (24, 30, 32) for use with a hip replacement where a femoral stem (14) includes a ball (22) component at its proximal end received within an acetabular cup assembly (10) to form a ball joint type coupling, and where the constraining device (24) includes a ring having a central aperture, where the ring is adapted to be mounted to a rim of the acetabular cup assembly so that the femoral stem passes through the central aperture, where the diameter of the central aperture is less than the diameter of the ball component on the proximal end of the femoral stem, and where the ring (24) comprises a biologic material, a biologically reabsorbable material and a combination of biologic, or biologically reabsorbable materials. Further embodiments of constraining devices for use with hip joints are disclosed: A mesh or webbing (30) used to hold the neck region of the femoral component (14), and a paste or glue (32) directed in proximity to the neck of a prosthesis and an acetabulum. |
