Filter by:Prospective, randomized study of Summit Porocoat versus Summit DuoFix HA in total hip arthroplasty
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.
The purpose of this study is to monitor the performance of the DePuy PROXIMA™ 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. A subset of patients will undergo scans to allow the bone mineral density of the bone surrounding the implant to be monitored
The purpose of this study is to monitor the stability of a total hip replacement within the thigh bone when used in artificial hip joints implanted with two different bone cements, Acryloc™ and Palacos® R, in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to Acryloc™ or Palacos® R and will be evaluated at regular intervals following hip surgery using patient, clinical, x-ray assessments and special x-rays which allow the stability of the hip implant to be determined
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.
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 December 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.
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.
