Our findings can be used to better identify patients at high risk of AMI and to develop strategies aimed at diminishing its incidence, which could in turn translate to improved hospital efficiency and quality of care.

In this study, 90 % of patients who developed a dislocation had properly positioned acetabular components. In addition, the vast majority of patients in the study group had adequate restoration of limb length and offset. The results of our study may be useful for the orthopedic surgeons who discuss instability following THA surgery, particularly in patients with radiographically sound reconstructions.
