A Multi-centre Study to Assess the Long-term Performance of the Pinnacle™ Cup With a Polyethylene-on-metal Bearing in Primary Total Hip Replacement

June 27, 2017 updated by: DePuy International

Uncontrolled Prospective Multi-Centre Post Marketing Surveillance Study to Monitor the Long Term Survivorship of Pinnacle Acetabular Cup System With a Metal on Enduron Polyethylene Bearing in Subjects With Aetiologies Requiring a Primary Total Hip Replacement

The purpose of this study is to monitor the performance of the Pinnacle™ Cup with a polyethylene-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.
