ICJR Interviews: The Durability of Hemiarthroplasty in Hip Fracture
Results of a recent retrospective chart review suggest orthopaedic surgeons should consider a cemented femoral stem when performing a hemiarthroplasty for a displaced femoral neck fracture.
After reviewing more than 700 cases in the New York Presbyterian Hospital at Columbia University database, William B. Macaulay, MD, and his colleagues concluded that a hemiarthroplasty with a cemented stem is more durable than a hemiarthroplasty with an uncemented stem, with a lower risk of periprosthetic fracture (0.7% for cemented vs. 1.4% for uncemented) and implant loosening (0.7% vs. 1.4%).
They also found that a unipolar head is just as effective as a bipolar head in hemiarthroplasty, but at a lower cost.
Overall, Dr. Macaulay said he and his colleague found hemiarthroplasty to be a good operation for these patients, with a low rate of conversion to total hip arthroplasty (THA) – although younger patients, probably because they are more active, are more likely to be converted to a THA.
