Total hip replacement requires the removal of the natural femoral head and the insertion of a hip stem down the shaft of the femur. Hip resurfacing, by contrast, preserves both the femoral head and the femoral neck.
During the procedure, your surgeon will only remove a few centimeters of bone around the femoral head, shaping it to fit tightly inside the BHR implant. Your surgeon will also prepare the acetabulum for the metal cup that will form the socket portion of the ball-and-socket joint.
The femoral component is cemented over the top of the prepared femoral head like a tooth cap, and the acetabular component is pressed into place much like a typical hip replacement component would be.
