Complex orthopedic cases such as thoracolumbar burst fractures and spinal vertebral body tumors have severe musculoskeletal damages, low satisfactory and high healthcare costs. Surgical planning is critical for these surgeries to ensure accurate patient evaluation and proper surgical design. Traditional surgical planning methods that rely on 2D medical images are unable to accurately reveal anatomic geometry of complex musculoskeletal damages. As a result, surgical planning is problematic and the clinical outcome is poor. Patient-specific 3D medical models allow the surgeon to plan and practice surgeries without to determine the correct surgical approach.
