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 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Harris Hip Score components including total score, pain, function and range of motion [ Time Frame: 10 years ] [ Designated as safety issue: No ]
  • device survival [ Time Frame: 10 years ] [ Designated as safety issue: Yes ]
  • device related adverse events [ Time Frame: 10 years ] [ Designated as safety issue: Yes ]
  • radiographic evaluation including radiolucencies, component migration, and femoral subsidence and tilt [ Time Frame: 10 years ] [ Designated as safety issue: Yes ]
  • whole blood trace metals and renal function [ Time Frame: 10 years ] [ Designated as safety issue: Yes ]

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: May 2018
Estimated Primary Completion Date: May 2018 (Final data collection date for primary outcome measure)
