Hip devices have a slightly greater risk of failing in women than in men, a recently conducted research suggests, revealing that women may have a 29 percent higher likelihood of experiencing repeat surgery within the first three years after a hip replacement procedure, regardless of the type of hip device.
The study by the United States Food and Drug Administration was reportedly published in JAMA Internal Medicine.
After looking at 35,000 surgeries at 46 hospitals in the Kaiser Permanente health system, the research team found that 2.3 percent of the women and 1.9 percent of the men went through revision surgery at an average of three years following after hip replacement surgery. Most of the complications reportedly associated with the hip devices were instability, infection, broken bones and loosening. While women have a higher likelihood of having a failing hip implant, lead author, Dr. Maria Inacio raises the observation that “This is still a very small number of failures.”
Women often need smaller prosthesis as their joints and bones are generally smaller in size than men, according to medical experts. However, devices with smaller parts are reportedly more prone to come out of the joint, necessitating a surgical repair. Experts have yet to find out the all the risk factors that may have contributed to the difference between women and men in the study although it is in theory that one contributing factor could be a greater loss of bone density in women. Although the absolute risk is low, online media reports highlight that women make up the majority of thousands of Americans who submit to total or partial hip replacement operations each year.
Metal-on-metal hip implants were also associated with nearly twofold increase in failure rate in women than in men, according to the study. While they were designed and sold as a more durable device compared to conventional implants, most implants with metal-on-metal bearings, such as those that have been affected the DePuy ASR hip replacement systems recall, have been reportedly linked to surprisingly higher failure rates.
