The VSS for preoperative planning of proximal femoral varus osteotomy. a Geomagic reverses reconstruction of DDH. b Place a 2.0 K-wire above the ventral surface of the femoral neck, which marks the anteversion of the femoral neck. c Apply the aiming block for 3.5 mm screws with help of the positioner for aiming device, in order to place the central guide wire approximately 10 mm distal to the physis of the greater trochanter. d Calculate the varus angle via Solidworks design software. e Simulate proximal femoral varus osteotomy. f The osteotomy was performed with LCP-PHP as preoperative planning
