Decreased head-neck ratio diameter and component malposition in total hip arthroplasty are factors known to result in impingement, increased rates of dislocation, wear and failure. In addition to these complications, impingement of the femoral neck on the acetabular component of a hip resurfacing may result in femoral neck fracture and loosening of

Metal ion release following hip replacement not strongly related to patient activity Read Complete Article by Clicking Here The amount of patient activity following metal-on-metal hip resurfacing arthroplasty seems to show little correlation to metal ion release, according to study presented here.

New York – May 15, 2013Metal-on-metal hip implants can cause inflammation of the joint lining (synovitis) long before symptoms appear, and magnetic resonance imaging (MRI) can be used to identify this inflammation, according to a new study by researchers at Hospital for Special Surgery. The study, which appears in an upcoming issue of the Journal … Read the rest
Staples significantly increase risk of postoperative infection studyMarch 2010
Original Link http://www.orthosupersite.com/view.aspx?rid=62584The use of staples to close wounds following orthopedic surgery – especially hip surgery – is associated with a significantly greater risk of wound infection than traditional suturing, according to orthopedic researchers from Norwich, England. Six clinical trials Toby O. Smith, MSc, BSc (Hons), MCSP, and colleagues analyzed the results of six trials that compared staples and

Adoption of Hip Resurfacing Arthroplasty at Hospital for Special Surgery: a Cohort Study
Edwin P. Su and Sherwin L. Su June 4, 2010
Background Hip resurfacing arthroplasty (HRA) is an alternative to traditional total hip replacement (THR) that allows for the preservation of femoral bone. It is a more technically difficult procedure that has led some researchers to report an unsatisfactory learning curve (Berend et al., J Bone Joint Surg … Read the rest
Joseph Daniel, Director of Research at the McMinn Center in Birmingham UK, talks about the 10 year survival of double heat-treated resurfacings from 1996 and the effect that these heat treatments had on this series of hip resurfacings.
