Clinical experience with three-dimensional printing techniques in orthopedic trauma

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Medical Imaging

Background:

• Three-dimensional (3D) printing is an emerging technology in orthopedic trauma.
• Its application in complex fractures requires further investigation.

Purpose of the Study:

• To report experiences with 3D printing in orthopedic trauma cases.
• To evaluate the utility of 3D printed bone models for surgical planning and education.

Main Methods:

• Retrospective study of 24 patients with acetabular (14) and clavicular shaft (10) fractures.
• Utilized 3D printed bone models for preoperative planning and surgical simulation.

Main Results:

• 3D acetabular models improved understanding of complex anatomy and fracture patterns, aiding reduction clamp positioning and screw trajectory planning.
• Pre-bending reconstruction plates using 3D models reduced operative time.
• Surgical simulation with 3D models improved guide wire positioning for percutaneous screw fixation and served as a valuable training tool for residents.
• 3D clavicle models facilitated optimal anatomical plate positioning for clavicular shaft fractures.

Conclusions:

• 3D printing significantly enhances surgeons' understanding of fracture patterns and anatomy.
• The technique is effective for preoperative planning, surgical trainee education, and simulation to optimize intra-operative outcomes.
