HIP IMPLANT FAILURE 29% HIGHER FOR WOMEN (Orthopedics This Week)
The failure rates for hip implants are 29% higher for women than they are for men, wrote John Gever, senior editor of MedPage Today. Gever was reporting on a study done by the Southern California Permanente Research Group in San Diego that examined the records of 35,140 patients and followed them for a mean of three years. The all-case rate of failure, involving subsequent revision surgery, was 2.3% for women and 1.9% for men, reported Maria C.S. Inacio, a member of the research group.
Gever wrote that after adjustments were made for age, body mass index, diabetes status, degree of pre-surgical symptom severity, implant fixation method, device category, and femoral head size, the authors calculated a hazard ratio for revision of 1.29% for women versus .95% for men. The researchers reported their conclusions online in JAMA Internal Medicine. The researchers found that the risk appeared most prominent for aseptic revision, compared with septic failure. Other factors leading to implant failure in women were larger femoral head sizes and metal-on-metal implants.
