Preplanning and simulation of surgery using rapid modelling

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Surgical Planning

Background:

• Rapid prototyping (RP) is a key technology in biomedical engineering.
• Additive manufacturing offers solutions for complex medical challenges.
• Acetabulum fractures require precise surgical intervention.

Purpose of the Study:

• To demonstrate how advanced imaging and RP can facilitate acetabulum fracture surgery.
• To explore the application of computed tomography (CT) images, CAD, and RP in a complex fracture case.
• To evaluate the impact of RP-assisted preplanning on surgical efficiency.

Main Methods:

• Utilized computed tomography (CT) imaging for detailed anatomical data acquisition.
• Employed three-dimensional computer-aided design (CAD) to model the fractured acetabulum.
• Applied rapid prototyping (RP) to create patient-specific surgical guides or models.
• Integrated advanced imaging and RP for pre-operative surgical planning and simulation.

Main Results:

• RP-based modeling enabled effective preplanning and simulation of the acetabulum fracture surgery.
• The integrated approach provided critical feedback during surgical procedures.
• Significant time savings were achieved during the surgery due to enhanced planning and simulation.
• Successful application demonstrated in a case of complex acetabulum fracture.

Conclusions:

• Advanced imaging techniques combined with rapid prototyping significantly facilitate complex acetabulum fracture surgery.
• RP-assisted surgical planning and simulation are effective in reducing operative time.
• This methodology offers a valuable tool for improving surgical outcomes in orthopedic trauma.
• The integration of CAD and RP enhances precision and efficiency in treating acetabular fractures.
