## Definition

Prosthesis, hip, semi-constrained, metal/metal, resurfacing device relieves hip pain and improves hip function by replacing the parts of the hip that have been severely damaged by degenerative joint diseases.  This device is indicated for patients with degenerative joint diseases including osteoarthritis, rheumatoid arthritis, traumatic arthritis, dysplasia, or avascular necrosis and for patients who, due to their relatively younger age or increased activity level, may not be suitable for traditional total hip replacement due to an increased possibility of requiring future hip joint revision.
