Pelvic anatomy-related indicators for evaluating feasibility of DAA and their measurement on a standard anteroposterior pelvic X-ray. A Left femoral neck fracture in a pelvis with normal anatomy related-index is strongly indicated for both DAA beginner and expert. B Bilateral high-dislocated developmental dysplasia of the hip in a pelvis with abnormal anatomy related-index is conditionally indicated for DAA expert. C Infection sequela of the right hip in a pelvis with abnormal anatomy related-index is fairly indicated for DAA beginner. Symbol illustration: a, the distance from inferior AIIS to superior GT (abbreviated as DGT-AIIS/DFH); b, the distance from lateral ASIS to lateral GT; c, pelvic width max, the maximal distance between bilateral ASIS; d, pelvic width min, the minimal distance between bilateral teardrop. Iliac crest angle, the angle between lines connecting the AIIS and the ischial tuberosity
