A 13 year old patient with bilateral coxa vara underwent a proximal femoral osteotomy that included virtual surgical planning and 3D printed patient-specific guides. Detailed anatomical modeling and advanced surgical planning processes were employed to create surgical simulations and patient-specific cutting guides. Various clinical parameters were documented, including the duration of the procedure and the patient's vital signs on the day of surgery. The costs  associated with 3D Printing and 3D Virtualization Technologies, and the surgery were calculated based on both labour and operating costs. Post-surgical evaluation included a survey with the lead surgeon reflecting on the impact of the 3D solutions used on implementation, communication, accuracy, efficiency, patient outcomes, and satisfaction.

Procedural time was 250 minutes. The surgeon reported that the 3D solutions shortened operating time, improved accuracy in achieving the desired Hip Shaft Angle correction and plate positioning, and increased overall confidence during the procedure. The models were shared with the patient and family, the clinical care team, and trainees, significantly enhancing their understanding of the disease, proposed surgery, as well as potential complications. The 3D solutions also improved consensus among the clinical care team regarding the treatment plan. Procedural time was significantly reduced, despite a slight increase in preoperative planning time. Additionally, the 3D solutions led to a significant reduction in fluoroscopy and radiation exposure. The surgeon was highly satisfied with the 3D solutions, citing their value in enabling the simulation of various angular corrections, predefining screw quantities and lengths, and improving inventory management. The ability to manipulate the virtual model in the operating room and take live measurements was identified as a key advantage. The total cost of implementing 3D solutions was CAD $3,806.21. 3D printed material costs were $868.00 and labour costs were $3,806.21. Total operating room costs were CAD $19,743.94. Operating room personnel costs were CAD $3,518.94 and operating room operating costs were CAD $16,225.00
