3D-printed navigation template in proximal femoral osteotomy for older children with developmental dysplasia of the hip Pengfei Zheng1,2,*, Peng Xu1,2,*, Qingqiang Yao2,3, Kai Tang1,2 & Yue Lou1,2 To explore the feasibility of 3D-printed navigation template in proximal femoral varus rotation and shortening osteotomy for older children with developmental dysplasia of the hip (DDH). Between June 2014 and May 2015, navigation templates were designed and used for 12 DDH patients. Surgical information and outcomes were compared to 13 patients undergoing the same surgery but without navigation template. In template-guided patient group, operation time (21.08 min vs. 46.92 min), number of X-ray exposures (3.92 vs. 6.69), and occurrence of femoral epiphysis damage (0 vs. 0.92) were significantly decreased (P
