Evaluation of the retroacetabular angle. a Post-intervention 3D projection of the retroacetabular angle. The planned osteotomy plane of the crucial retroacetabular OT is depicted in red and the yellow plane shows the actual performed osteotomy plane. b 2D projection of the 3D planes. The angle between these two planes was measured in a 2D fashion. A large aberration of the performed to the planned angle could lead to a posterior column or intraarticular osteotomy
