Video Summary

This study compared radiographic measurements of the hip from standing versus supine AP pelvis radiographs in hip preservation patients. Key findings include that supine radiographs are more likely to show positive crossover and ischial spine signs, while standing radiographs yield lower lateral center edge angles and acetabular depth, and higher acetabular inclination. Since pelvic tilt affects these diagnostic measurements influencing treatment plans, standing AP pelvis radiographs provide a more consistent and functional view. The authors recommend obtaining standing radiographs for all hip preservation patients to improve diagnostic accuracy and treatment planning.
