Study: Hip resurfacing arthroplasty and effects on bone mineral density

Hip resurfacing preserves bone mineral density, bone stock, but disadvantages must be considered (Healio)
Although there is a high level of evidence that hip resurfacing arthroplasty preserves bone mineral density and bone stock in the proximal femur, the clinical relevance should be weighed against potential disadvantages, such as a higher revision rate for metal-on-metal bearings, according to researchers.
To determine whether bone mineral density (BMD) was preserved without significant femoral neck narrowing (FNN), the researchers randomly assigned 42 patients who needed primary hip arthrop...
