Computer-assisted virtual surgical procedure for acetabular fractures based on real CT data

Abstract

Objective: To develop and evaluate a computer-assisted virtual surgical procedure for preoperative planning that simulates the reduction and plate fixation for acetabular fractures based on real computed tomography (CT) data using computer softwares on personal computers.

Methods: Virtual preoperative planning for reduction and plate fixation for seven acetabular fractures was performed. Three-dimensional (3D) models of acetabular fractures based on real CT data in Dicom format were built to perform reduction first. Then fixation was undertaken after plate contouring. Virtual planning was compared with real surgery with respect to operative approach, plate length and screw count. Furthermore, the time required for virtual surgery was recorded.

Results: Virtual surgery was successfully achieved and identical to the real operation in all cases. The mean time required was 79 min.

Conclusion: The virtual surgical procedure for acetabular fractures is feasible and useful clinically for surgeons to determine surgical planning. It may be a valuable tool for surgeons in learning about the nature of the fracture and in formulating an appropriate surgical plan.
