Abstract

About 4 % of THA patients suffer from iliopsoas syndrome (IS). Modelling of the iliopsoas muscles is considered to be a reasonable aspect for identification of risk factors for IS. In this study we modelled the m. iliacus and the m. psoas major as separate muscles, consisting of 3 fascicles each. We analysed length and angular change of the fascicles from preoperative to postoperative state in a reference position on a database of 201 Japanese patients that underwent unilateral primary THA, with five of these patients being diagnosed with IS postoperatively. We did not find any correlation between length and angular changes and the appearance of IS. Further investigation is needed to find relevant risk factors for prediction of IS.
