Further study details as provided by Corin:

Primary Outcome Measures:
  • to monitor the clinical performance of the Cormet implant system for a period of up to 10 years postoperative in order to confirm that there are no unexpected reductions in device performance following PMA approval [ Time Frame: 10 years ]

Secondary Outcome Measures:
  • Harris Hip Score components including total score, pain, function and range of motion [ Time Frame: 10 years ]
  • device survival [ Time Frame: 10 years ]
  • device related adverse events [ Time Frame: 10 years ]
  • radiographic evaluation including radiolucencies, component migration, and femoral subsidence and tilt [ Time Frame: 10 years ]
  • whole blood trace metals and renal function [ Time Frame: 10 years ]

Biospecimen Retention:   Samples With DNA
blood specimens for metal ion testing and renal function testing

Estimated Enrollment: 350
Study Start Date: May 2008
Estimated Study Completion Date: March 2018
Estimated Primary Completion Date: March 2018 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
IDE subjects who received the Cormet Hip Resurfacing device
Device: Cormet Hip Resurfacing System
Cormet Hip Resurfacing System
Other Name: Corin Cormet

Detailed Description:
Maintaining "at least good clinical status" will be determined based upon the composite clinical success (CCS) criterion which includes no revision, removal, or replacement of any device component and a Harris Hip Total score of greater or equal to 80 points.
