Vigdorchik JM, Sharma AK, Madurawe CS, et al. - This study was sought to characterize the spinopelvic risk factors and quantify the prevalence of risk factors for pathologic spinopelvic mobility. Between January 2014 and February 2020, researchers performed a retrospective cohort analysis on a multicenter series of 9,414 primary total hip arthroplasty (THA) by 168 surgeons, all with preoperative spinopelvic measurements in the supine, standing, and flex-seated positions. It was shown that 46% of patients had spinopelvic pathology driven by one or more of the risk factors. The results indicated that the number of risk factors present and, risk of adverse spinopelvic mobility were positively correlated, with 57% of patients with all three risk factors exhibiting adverse spinopelvic mobility. As per the findings, although this research characterizes the prevalence of these risk factors in this highly selected cohort, it does not report incidence in a general THA population.
