In this prospective study, 190 hip resurfacing procedures (164 participants) were performed using a cobalt-chromium femoral component and a cementless acetabular cup with a 3.8-mm highly cross-linked polyethylene acetabular liner…

…it may be beneficial to investigate the long-term outcome of hip resurfacings using metal-on-polyethylene in the 1980’s. We report the long-term survivorship and modes of failure of a cementless metal-on-polyethylene resurfacing.
Ongoing developments using the lessons learned from these previous generation components and utilizing modern low wear materials, e.g., cross-linked polyethylene, may … Read the rest

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
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.
Hip Resurfacing With the Biomet Hybrid ReCap-Magnum System: 7-Year Results by Dr. Gross & Fei Liu 2012
|Gross TP, Liu F. – Midlands Orthopaedics, P.A., Columbia, SC. Abstract The purpose of this study was to report our clinical outcome of a large series of metal-on-metal hip resurfacing arthroplasty (HRA) using the hybrid Biomet ReCap-Magnum system. This is a single-designer surgeon series with an average of 5 ± 1 years. Seven|
|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
