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 the acetabular component.

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 size of the coverage angle

Abstract

INTRODUCTION: 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 of femoral bone stock, increased
