Study Details

Brief summary:

The purpose of this study is to use Radiostereometric Analysis (RSA) and clinical outcome measures to evaluate early, post-operative implant stability, post-operative implant fixation, clinical performance, and in-vivo wear of the Zimmer® Continuum® Cup with vitamin E stabilized polyethylene.

Interventions and Outcome Measures

Arms

other: Vitamin E Polyethylene and RSA

All subjects will have the Vitamin E polyethylene and RSA beads placed during surgery. Subjects will then have standard x-ray images and RSA images taken at specific time points up until 2 years post-operatively.

Primary outcome measure

  • Assessing the Continuum® Cup for adequate fixation to the underlying bone as measured by migration and tilt [ Time Frame: 2 years ]
  • Assessing the migration pattern of the Continuum® Cup [ Time Frame: 2 years ]
  • Determining a correlation between radiolucent lines (RLLs) measured by Charnley-DeLee Zone Analyses and migration characteristics using RSA [ Time Frame: 2 years ]
  • Determine if inducible displacement is indicative of adequate fixation [ Time Frame: 2 years ]
  • Assess the health status and functional outcome of patients with the Continuum® Cup [ Time Frame: 2 years ]
  • Assess the wear rate of the Vitamin E polyethylene with a ceramic femoral head [ Time Frame: 2 years ]
  • Determine if the wear rate of the Vitamin E liner is the same in-vivo as it is in simulation testing [ Time Frame: 2 years ]
