Filter by: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.
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.
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.
To demonstrate the safety and efficacy of the Cormet Large Diameter Metal on Metal (LDMOM) Total Hip System using a composite clinical success (CCS) primary endpoint.
Long-term follow-up of IDE patients for publication
The purpose of this study is to perform a five-year, prospective evaluation of the Copeland™ Humeral Resurfacing Head Prosthesis for outcome and durability. Relief of pain and restoration of function will determine long-term clinical outcome while durability will be measured by the absence of revisions.
The purpose of this prospective clinical data collection is to document the performance and clinical outcomes of the M2a- Taper™ Hip System
The purpose of this prospective clinical data collection is to document the performance and clinical outcomes of the M2a- 38™ Hip System
This study is being conducted to gather medium and long-term information regarding the performance and safety of the commercially available DURALOC® Option Ceramic-on-Ceramic Hip Prosthesis System.
This study uses the cholesterol lowering drug atorvastatin, also known as lipitor, to show reduction of avascular necrosis in steroid treated lupus patients. Avascular necrosis is a disease resulting from the loss of blood supply to the bones which can cause the bone to collapse. The collapse of bone may require a surgical replacement of the joint and can be disabling for life. Avascular necrosis is presently not preventable but research has shown that lipid lowering drugs such as lipitor can reduce or prevent avascular necrosis in animals. We therefore hypothesize that lipitor will reduce the incidence of avascular necrosis in lupus patients taking high dose steroids.
