Filter by: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.
The purpose of this study is to monitor the performance of artificial hip joints implanted with two different bone cements, SmartSet® HV and SmartSet® GHV, in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to SmartSet® HV or SmartSet® GHV and will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments
The aim of this study is to evaluate a simple and rapid method in order to better define and treat Polymyalgia Rheumatica by measuring levels of muscle achiness and pain with a blood pressure cuff.
Osteoporotic vertebral fracture (VF) and osteonecrosis of the femoral head (OFH) are major concerns in patients with systemic rheumatic diseases treated with high-dose glucocorticoids (GCs). The investigators examined and compared the incidence and risk factors of VF with those of OFH in patients who had recently received high-dose GC therapy to clarify the relationship between these two complications.
This pilot study will explore the usefulness of a series of questions asking about views of research from the perspective of minority and economically disadvantaged research participants. Racial and ethnic minorities are consistently under-represented in clinical research. This under-representation has been attributed primarily to an unwillingness to participate in research because of mistrust in the research establishment, especially in light of widely known historical examples of abuse. However, more recent data suggests that not being invited to participate in research, or stringent entry criteria, may contribute substantially to the low numbers of ethnic minority research participants. The perspectives of racial and ethnic minorities who are knowledgeable about or participating in research are important to understanding the kinds of vulnerabilities that exist and any important barriers to participation. People 18 years of age and older from the Cardozo clinic in Washington, D.C., who are enrolled in the National Institute of Arthritis and Metabolic Studies' natural history study are eligible to participate in this protocol. Participants are interviewed with questions about their own experiences in clinical research as well as some hypothetical research studies. Questions include participants' general views of clinical research, perceived risks and benefits of research, alternatives to research participation, the limits of what they would be willing to accept in research and types of research or research procedures they might perceive as unfair.

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 compare the performance and compare the wear characteristics of two polyethylene cup liners, Marathon™ and Enduron™, in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to one of the polyethylene cup liners, Marathon™ or Enduron™ and will be evaluated at regular intervals using clinical and x-ray assessments.
