NCT ID: NCT00872794 Terminated - Clinical trials for Rheumatoid Arthritis

A Single Centre Study to Assess the Long-term Performance of the DePuy ASR™ System in Primary Hip Resurfacing Surgery

Start date: November 2003
Phase: Phase 4
Study type: Interventional

The purpose of this study is to monitor the performance and determine the metal ion release of the DePuy ASR™ System in the treatment of patients with hip joint disease requiring hip resurfacing surgery. 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 and undergo scans to allow the bone mineral density of the bone surrounding the implant to be monitored. DePuy decided to close this Study in 4Q 2009. The Study was terminated with effect from November 2010 to allow for the completion of the 5 year follow up assessments. Please note that subsequent to this decision DePuy voluntarily recalled the ASR products on 24 August 2010. Additional information regarding this voluntary recall and the follow-up of patients affected by the recall can be found at the following links http://www.mhra.gov.uk/Publications/Safetywarnings/MedicalDeviceAlerts/CON079157 and http://www.depuy.com/countries_list.

NCT ID: NCT00872573 Terminated - Clinical trials for Rheumatoid Arthritis

A Two Centre Study to Assess the Stability and Long-term Performance of the C-Stem™ AMT in a Total Primary Hip Replacement

Start date: July 1, 2006
Phase: Phase 4
Study type: Interventional

The purpose of this study is to monitor the stability of the C-Stem™ AMT hip within the thigh bone when used 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, standard x-ray assessments and special x-rays which allow the stability of the implant to be determined.

NCT ID: NCT00872547 Terminated - Clinical trials for Rheumatoid Arthritis

Multi-Centre Study to Assess the Long-term Performance of the DePuy ASR™ System in Resurfacing and Primary Total Hip Replacement

Start date: September 2006
Phase: Phase 4
Study type: Interventional

The purpose of this study is to monitor the performance of a large metal-on-metal bearing from the DePuy ASR™ System in the treatment of patients with hip joint disease requiring hip resurfacing surgery or 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. The Study was terminated with effect from 30th November 2011 following the completion of 2 year follow up assessments for those patients remaining in the study. Please note that prior to this decision DePuy voluntarily recalled the ASR products on 24 August 2010. Additional information regarding this voluntary recall and the follow-up of patients affected by the recall can be found at the following links http://www.mhra.gov.uk/Publications/Safetywarnings/MedicalDeviceAlerts/CON155761 and http://www.depuy.com/countries_list.

NCT ID: NCT00872222 Terminated - Clinical trials for Rheumatoid Arthritis

A Single Centre Study to Assess the Long-term Performance of the Pinnacle™ Cup With a Ceramic-on-ceramic Bearing in Primary Total Hip Replacement

Start date: January 2007
Phase: Phase 4
Study type: Interventional

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

NCT ID: NCT00208468 Terminated - Osteoarthritis Clinical Trials

A Randomised Multi-centre Study to Compare the Long-term Performance of the Future Hip to 3 Other Implants in Primary Total Hip Replacement

Start date: February 2000
Phase: Phase 3
Study type: Interventional

This post-market clinical follow-up study was designed to compare hip replacement outcomes of the European Hip against 3 controls (Omniflex, Zweymuller, and Spotorno), however Omniflex did not end up being used. The first patient had surgery on February 18, 2000 and the final patient had surgery on September 2, 2005. There were 317 subjects consented but only 301 had hip replacement surgery (subjects received: 220 European hips, 33 Zweymuller, and 48 Spotorno). The study took place at three sites. Each site used their standard device as the control. The Austrian site enrolled 69 European hips and 33 Zweymuller hips. 92 European hips and 48 Spotorno hips were enrolled in Germany. Finally, the site in Italy enrolled 59 European hips. Although the study protocol intended collecting DEXA and RSA outcomes, the data collected by the sites did not include these outcomes.

NCT ID: NCT00208390 Terminated - Clinical trials for Rheumatoid Arthritis

A Multi-centre Study to Assess the Long-term Performance of the Summit™ Hip in Primary Total Hip Replacement

Start date: February 2003
Phase: Phase 4
Study type: Interventional

The purpose of this study is to monitor the performance of the Summit™ hip 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.
