Hip resurfacing with metal components was first approved by the FDA in 2006. The procedure is called a metal-on-metal hip resurfacing (MOMHR).
A study of more than 2,000 patients showed this treatment was safe and effective with good results after a five-year follow-up period. This procedure preserves bone and extends the life of the joint. Patients who have severe hip pain without severe joint or bone destruction may want to consider this treatment option.
With MOMHR, hip motion and function are restored more toward the normal biomechanics compared with total hip replacement (THR). And by saving as much bone as possible, you may be able to have a THR later if needed. Studies show that the more skilled the surgeon, the more bone is preserved.
