Abstract
Abstract Background Accurate evaluation of acetabular morphology, pelvic orientation, and the hip–spine relationship is very important in hip preservation surgery. Conventional radiographs are still the standard in most places, but they give only a static two-dimensional view and can be affected by magnification and calibration issues. EOS imaging is a newer low-dose system that allows standing imaging and three-dimensional reconstruction. Even though it is getting more attention, its real role in hip preservation is still not clearly established. Purpose To systematically review the current literature on EOS imaging in hip preservation, focusing on reliability, measurement characteristics, functional assessment, and its potential clinical usefulness. Methods This study was performed following PRISMA principles. A systematic search of PubMed, Embase, and the Cochrane Library was done. We included studies that evaluated EOS imaging in hip preservation, including acetabular morphology, pelvic parameters, hip–spine relationship, biomechanical analysis, and preoperative planning. Results A total of 10 studies were included. These studies looked at different aspects of EOS use, including acetabular measurements, three-dimensional orientation, hip–spine alignment, biomechanical applications, measurement accuracy, and templating or preoperative planning. Only a few studies were directly focused on classic hip preservation patients, and many of the findings come indirectly from related areas. In terms of measurements, EOS showed good reliability, which was generally similar to conventional radiographs. However, several studies showed that there are small but consistent differences between EOS and standard radiographs. Because of this, the two methods should not be used interchangeably without caution, especially when comparing values over time. One of the main advantages of EOS is the ability to evaluate patients in a standing, functional position. Some studies showed that functional alignment can be different from anatomical alignment, and this difference is often related to pelvic tilt. This may be important in certain patients, especially when looking at hip–spine interaction. EOS also allows three-dimensional assessment, which helps to better understand individual variation in acetabular orientation. Other practical advantages include less magnification error, less dependency on calibration, and more consistent results in templating. EOS was also used as a reliable reference in some biomechanical studies. At the same time, there is still no clear consensus about its routine use, and current evidence does not show consistent improvement in clinical outcomes. Conclusion EOS imaging seems to be most useful for evaluating the hip–spine relationship, functional pelvic alignment, and in some aspects of preoperative planning such as templating. However, differences in measurements compared to radiographs, limited direct evidence in hip preservation, lack of consensus, and no clear proof of improved outcomes make it difficult to recommend routine use at this time.
