Fig. 1. The 4-week postoperative radiograph from a left total hip arthroplasty performed without an intraoperative radiograph (No X-ray group) shows the cup at 44° of abduction (yellow line) and 30° of anteversion (yellow ellipse). The left leg is 6.5 mm (8.3–1.8 mm) shorter than the right leg and has 5.9 mm (100.6–94.7 mm) less offset.
