Metal and Plastic Implants. A prosthetic made of metal and plastic are the most commonly used hip replacement implants. Both the ball and the socket of the hip joint are replaced with a metal implant, and a plastic spacer is placed in between. The most commonly used metals used include titanium and stainless steel.
Surface Replacement of the Hip. In surface replacement, the femoral neck is preserved rather than amputated as is done in conventional stem-type total hip replacement. The femoral head is reshaped and resurfaced with a prosthetic shell.
