Intra- and inter-rater reliability of spinopelvic measurements in functional positions for total hip arthroplasty
This study demonstrates that Spino-Pelvic Tilt and Sacral Slope offer superior intra- and inter-rater reliability compared to Anterior Pelvic Plane tilt for assessing pelvic tilt in functional positions during total hip arthroplasty planning, leading to a recommendation to prioritize the former two measurements.
