Is there a tendency for the femoral head to die under the resurfacing implant?
This is a common misconception as it was once thought to be the reason some previous attempts at resurfacing were not successful. Here is a copy the abstract of a recent study on the question. J Arthroplasty 2000 Jan;15(1):120-2 Viability of femoral heads treated with resurfacing arthroplasty. Campbell P, Mirra J, Amstutz HC. ” There is a general conception that resurfacing arthroplasty causes femoral head osteonecrosis and subsequent failure of the implant. This study histologically analyzed 25 resurfaced femoral heads up to 12 years postoperatively and found that osteonecrosis was not induced by the procedure.” • Does the resurfacing implant remove more bone from the pelvis than a standard total hip replacement? Because the head is significantly larger than that of the standard total hip replacement, one might think that more bone would need to be removed on the pelvis side, but this is generally not true. The outside diameter of the acetabular component is similar in size to the typ
