Illustration of HU value thresholding, FEA and intraoperative surgical techniques. A The identification of calcar femorale (arrowhead) and lateral cortical bone based on HU value thresholding. B The identification of trabecular bone based on HU value thresholding showing principle compressive trabecular bone (arrowhead), principle tensile trabecular bone (empty arrowhead) and Ward triangle (arrow). C The biomechanical distribution of the proximal femur analyzed by finite elements showing the direction and location of the applied loading force. D The lateral approach for the exposure of the proximal and middle thigh. E Intraoperative application of the 3D-printed osteotomy guide plate. F The resected tumor-involved segment
