First and second postop measurements were performed within one week after surgery and after a minimum of 180 days, respectively. M, male; F, female; CE, centre-edge angle; preop, preoperative; postop, postoperative; LCPD, Legg-Calvé-Perthes disease; DDH, developmental dysplasia of the hip; N/A, suboptimal projections making reliable measurements difficult
