Correlation between score values and morphofunctional parameters in THA

EPiC series in health sciences, vol. 6, pp. 1–

Abstract

Morpho-functional analysis is a major aspect of preoperative planning for THA. This study aims to investigate whether pain or movement restrictions correlate with the morphofunctional parameters pelvic tilt, pelvic bend and pelvic rotation. Pre- and postoperative CT and EOS images, as well as score values of 201 Japanese patients were analyzed. No statistical relevant correlation between the score values and the parameters could be found (|rmax| = 0,38). However, the statistical power was found to be low for our data ((1-β ~ 0.10). Further research with larger data sets is desirable.
