Precision of CT-based micromotion analysis is comparable to radiostereometry for early migration measurements in cemented acetabular cups
Background and purpose—CT (computed tomography) based methods have lately been
considered an alternative to radiostereometry (RSA) for assessing early implant migration …

Hip prosthetic loosening: A very personal review
B Mjöberg - World journal of orthopedics, 2021 - pmc.ncbi.nlm.nih.gov
Hip prosthetic loosening is often difficult to detect at an early stage, and there has been
uncertainty for a long time as to when the loosening occurs and thus to the basic causes. By …
