|Larger cups and optimal positioning produced lowest ion
levels and wear
In a review of 585 blood serum evaluations following hip resurfacing, only femoral size and cup inclination were found to have an effect on ion levels, according a study by orthopedic investigators.
The findings were presented at the 2010 Annual Meeting of the American Academy of Orthopaedic Surgeons.
David J. Langton, MRCS, and his colleagues also found that the

AbstractINTRODUCTION: Metal-on-metal hip resurfacing has provided an alternative to standard total hip arthroplasty in younger, more active patients. However, detractors argue that many of the benefits of resurfacing can be obtained with the use of larger femoral heads. The purported advantages of the resurfacing procedure include preservation
|Archive of failed joint replacements provides tips to building a better hip replacementA study by Hospital for Special Surgery researchers has provided the first comprehensive look at just how metal-on-metal total hip replacements are failing in patients around the country. Made possible by what is thought to be the largest archive of failed joint replacements, the research should help doctors develop a better hip replacement for future patients. The study|
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.
