The controversy regarding adverse wear in metal-metal bearings
Thomas P. Gross, MD 3/5/2010
I have used over 3000 metal bearings in primary total hip and hip resurfacing as well as revision surgery. I have revised 2 for adverse wear 7 years after implantation. I know that most other high volume hip resurfacing surgeons have a similar experience. The revisions were straightforward and the patient enjoyed the same rapid and complete

The lubricant has more in|

Rush University Medical Center Study Finds More Complications in Women and in Males Over the Age of 55 CHICAGO – Hip resurfacing is often seen as a modern alternative to the more conventional total hip replacement, but new data from a study led by Rush University Medical Center suggest that a patient’s age and gender are key to the operation’s success.In a review of
Does commitment to rehabilitation influence the clinical outcome of total hip resurfacing arthroplasty study 2010
|The purpose of this study was to evaluate whether compliance and rehabilitative efforts were predictors of early clinical outcome of total hip resurfacing arthroplasty. Methods: A cross-sectional survey was utilized to collect information from 147 resurfacing patients, who were operated on by a single surgeon, regarding their level of commitment to rehabilitation following|
The femoral head shell Onlay is a hip resurfacing of the latest generation. It is manufactured by ESKA Implants. The minimal invasive implant permits an unique bone- preserving surgical procedure.For the Pure Resurfacing the femoral head only gets modified the surface with a broach, before it gets crowned with the Pure Resurfacing Onlay. The bone substance remains completely unaffected and the further wear of the joint is haltered.
