Detailed 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).

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

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).
