Filter by:This is a post-approval study with prospective enrollment in the United States and a retrospective enrollment outside the United States to obtain functional, quality of life and radiographic data, which will facilitate assessment of the clinical performance of the Zimmer Trilogy AB Acetabular Hip System.
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.
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
