The instantly disclosed implant is designed to resurface or partially replace (two versions) the arthritic or osteonecrotic femoral head in an anatomic fashion with maximum fixation, durability and stability. It will serve a wide range of patient ages, arthritic/traumatic deformity, and bone pathologies while providing for high performance activity. The implant has absolute fixation utilizing existing, contoured femoral head bone with or without bone cement/porous texturing, an internal plate with modular head attachment, and advantageously benefit from the concurrent use of precision guided instrumentation. This implant optimizes maximal femoral head contact with or without porous contact surfaces but does not rely purely on the head for long term stability. This new concept prevents the common failure mechanisms of femoral neck fracture, loosening and malpositioning as well as makes patient bone quality less important for this high performance hip resurfacing implant.
