One visualization simulation operation system for distal femoral fracture

Area of Science:

• Orthopedic Surgery
• Medical Imaging
• Computer-Aided Design (CAD)

Background:

• Distal femoral fractures present complex challenges in surgical treatment.
• Accurate preoperative planning is crucial for successful orthopedic interventions.
• Existing methods may lack the detailed visualization needed for complex fractures.

Purpose of the Study:

• To establish a computer-aided 3D visualization operation simulation system for distal femoral fracture treatment.
• To provide orthopedic surgeons with a reliable tool for preoperative planning and surgical guidance.
• To enhance the accuracy and safety of surgical interventions for distal femoral fractures.

Main Methods:

• Utilized Mimics software for 3D reconstruction of distal femoral fractures from CT data.
• Employed computer-aided design (CAD) Unigraphics NX for surgical instrument modeling and measurement.
• Simulated surgical procedures, including fixation with less invasive stabilization system (LISS) and retrograde intramedullary nail fixation.

Main Results:

• Successfully established a functional 3D visualization and simulation system.
• Demonstrated the system's capability to provide actual, visualized, and lifelike surgical simulations.
• Enabled preoperative estimation of surgical outcomes for distal femoral fracture treatment.

Conclusions:

• The developed system effectively assists in the treatment of distal femoral fractures using LISS and retrograde intramedullary nail fixation.
• The virtual surgery system enhances the reliability and safety of operative care.
• This technology offers a promising advancement in preoperative planning for complex orthopedic cases.
