Eligibility Criteria

Male or female participants of any age.

Inclusion Criteria: - Male or female patient who meets eligibility criteria consistent with product labeling - skeletally mature - mentally capable of completing follow-up forms - Will be available for follow-up out to 2 years and annually thereafter until the last patient reaches the two-year evaluation - Has been deemed a candidate for hip replacement by diagnosis of the investigator - consented to participate in the clinical study Exclusion Criteria: - Patient with active or suspected infection in or around the hip joint; - Patient with bone stock inadequate to support the device - Patient with severe osteopenia - Patient with a family history of severe osteoporosis or severe osteopenia; - Patient with osteonecrosis or avascular necrosis (AVN) with >50% involvement of the femoral head (regardless of FICAT Grade) - Patient with multiple cysts of the femoral head (>1cm) - In cases of questionable bone stock, a DEXA scan may be necessary to assess inadequate bone stock. - Patient with any vascular insufficiency, muscular atrophy, or neuromuscular disease severe enough to compromise implant stability or postoperative recovery; - Female of child-bearing age due to unknown effects on the fetus of metal ion release. - Patient with known moderate or severe renal insufficiency; - Patient who is immunosuppressed with diseases such as AIDS or person receiving high doses of corticosteroids; - Patient who is severely overweight; - Patient with known or suspected metal sensitivity (e.g., jewelry).

Additional Information

Official title Cormet Resurfacing Hip System Post PMA-Approval Study Post-approval Study Group (New Enrollment)
Description This study tracks the performance of the Cormet Hip Resurfacing system in the post-approval environment to see if there are significant changes in device performance from the pre-market IDE setting as compared to the post-approval setting. Specifically this study will compare the proportion of subjects achieving a Month 24 composite clinical success (CCS) criterion and 24 month cumulative revision rate among the newly enrolled post-approval study subjects to the IDE subjects' performance on CCS as reported in the Pre-Market Application (PMA).
