The CE angle measured automatically from X-ray projections changed from 21° preoperatively to 29° postoperatively. a Preoperative CT slice and b a zoomed in region about the acetabulum. c Preoperative CT slice with a postoperative overlay and d a zoomed in region about the acetabulum. In these displays, the postoperative was highlighted with a color-based filter to distinguish it from preoperative; the blue dots are coloring effects due to the intensity of the fixation screws. e Postoperative CT slice and f a zoomed in region about the acetabulum
