A Two Centre Study to Assess the Long-term Performance of the Pinnacle™ Cup With a Metal-on-Metal Bearing in Primary Total Hip Replacement
Uncontrolled Prospective Multi-Centre Post Marketing Surveillance Study to Monitor the Long Term Survivorship of Pinnacle Acetabular Cup Prosthesis With a Metal on Metal Bearing in Subjects With Aetiologies Requiring a Primary Total Hip Replacement
The purpose of this study is to monitor the performance and determine the metal ion release of the Pinnacle™ Cup with a metal-on-metal bearing combination in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments. A subset of patients will also have blood samples taken at regular intervals to allow the metal ion levels to be determined.
