Summary
This study introduces a novel tool for planning surgeries for pelvic and acetabular fractures. The system uses patient-specific models and virtual simulations to improve surgical accuracy and reduce operation time.
Area of Science:
- Orthopedic Surgery
- Medical Imaging
- Biomechanical Engineering
Background:
- Pelvic and acetabular fractures present significant challenges in trauma surgery.
- Current treatment planning methods may lack precision and efficiency.
Purpose of the Study:
- To present a novel tool for intervention planning of pelvic and acetabular fractures.
- To enhance surgical planning through patient-specific modeling and virtual simulation.
Main Methods:
- Development of a planning tool utilizing Computed Tomography (CT) data for patient-specific bone models.
- Incorporation of virtual reduction of bone fragments and virtual adaptation of osteosynthesis implants.
- Integration of Finite Element Analysis (FEA) for mechanical behavior assessment of the surgical plan.
- Utilizing an intuitive visuo-haptic interface for trauma surgeons.
Main Results:
- The tool allows for determination of osteosynthesis material type and size.
- Measurements of distances and angles relative to landmarks can be accurately taken.
- Initial prospective results demonstrate excellent correlation and a significant reduction in operation time.
Conclusions:
- The presented tool offers a promising approach for improving the planning and execution of surgeries for complex pelvic and acetabular fractures.
- Virtual planning and simulation can lead to enhanced surgical outcomes and efficiency.
