Commentary: Hip Implant Failure for Men, Women
In a related commentary, Diana Zuckerman, Ph.D., of the National Research Center for Women & Families, Washington, D.C., writes: "Sex-specific analyses are especially important in orthopedics because of substantial anatomical sex differences. These data of Inacio et al provide an important first step in understanding higher THA revision rates in women."
"Longer follow-up is necessary for hip implants, and the relatively small number of revisions and large number of potentially confounding variables in these short-term data make it challenging to use these data to help reduce the likelihood of revision surgery," Zuckerman continues.
"What is urgently needed is long-term comparative effectiveness research based on larger sample sizes, indicating which THA devices are less likely to fail in women and in men, with subgroup analyses based on age and other key patient traits, as well as key surgeon and hospital factors. Such data would enable p
