Three-Dimensional Hands-on Total Hip Arthroplasty Simulation After Surgically Treated Acetabular Fractures: A...

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Radiology

Background:

• Delayed total hip arthroplasty following acetabular fractures presents surgical challenges due to altered anatomy and existing hardware.
• Standard radiological methods struggle to accurately assess bone defects in the presence of in situ osteosynthesis material.

Purpose of the Study:

• To evaluate the utility of multicoloured 3-dimensional-printed acetabular models for preoperative surgical planning.
• To optimize acetabular component positioning in complex revision hip arthroplasty cases.

Main Methods:

• Development of patient-specific, multicoloured 3D-printed acetabular models.
• Simulation of acetabular component placement using the 3D models.
• Comparison with standard radiological assessments.

Main Results:

• 3D models provide enhanced visualization of complex acetabular anatomy and bone defects.
• Simulated component positioning on 3D models aids in planning optimal implant placement.
• Facilitates better understanding of challenges posed by in situ osteosynthesis material.

Conclusions:

• Multicoloured 3D-printed acetabular models are valuable tools for preoperative planning in delayed total hip arthroplasty after acetabular fractures.
• These models improve the assessment of bone defects and simulation of component positioning.
• Enhances surgical decision-making and potentially improves outcomes in complex cases.
