Acetabular Component Migration Following Revision Total Hip Replacement
type: CreativeWork
description: Background: The most common reason for revision of the acetabular component after total hip replacement (THR) is loosening. Identifying a surrogate, such as early migration, that could predict the long-term performance of revision acetabular components and techniques is important given the introduction of new implants and techniques. Radiostereometric Analysis (RSA) and Ein-Bild Roentgen Analyse (EBRA-Cup) are the only validated methods to measure component migration that can predict long-term survivorship of primary THR implants. The advantage of EBRA-Cup is that it can be performed retrospectively, and therefore, is currently arguably the best method to establish thresholds for component migration that predict component loosening. The advantage of RSA is that it is the most accurate method to measure component migration and the current gold standard. If EBRA-Cup established thresholds of migration could be applied to RSA measurements, RSA could be used to predict loosening of revision acetabular components and therefore assess the early performance of various components as well as the effect that variation in technique can have on the performance of components. Aims: The aims of this thesis were: (1) to undertake a scoping review of all studies that used RSA, to measure the migration of acetabular components used at revision THR. (2) To determine the amount of acetabular component proximal translation and sagittal rotation as measured by EBRA-Cup after revision THR to predict and (3) diagnose aseptic loosing at re-revision surgery. (4) To determine the accuracy of EBRA-Cup measurements of uncemented acetabular component migration after revision THR, and (5) to compare the number of cases identified using EBRA-Cup and RSA as having proximally migrated above and below 1mm at 2 years post-operatively. (6) To compare the migration of the revision acetabular system thought to have the best results to treat severe bone defects, using porous tantalum acetabular component…
