Establishment of three-dimensional simulation model of acetabular fracture and its significance / 中华创伤杂志

ABSTRACT

Objective To establish three-dimensional (3D) simulation model of acetabular fracture based on Letournel-Judet classification and analyze its significance. Methods Pelvis of one healthy female volunteer was scanned with 16 slice spiral CT. Dicom format data were processed by software Mimics 10.01 to reconstruct 3D model of hip bone. Different fracture types were simulated based on Letournel-Judet classification of acetabular fracture. The fracture fragments were displayed with different color. Screen-captures of fracture model from different directions were saved and video mode of fracture model was exported. Five orthopedic doctors and 10 medical students were employed to compare 3D fracture model with two-dimensional planar schematic diagram and made preliminary evaluation. Results The 3D simulation model of acetabular fracture had realistic form and stereoscopic sense, with satisfactory visual effect. The fracture could be observed and charted from optional direction and angle. Fracture model could rotate for 360° in the corresponding video mode. Four orthopedic doctors and nine medical students considered that 3D simulation model of acetabular fracture was helpful for understanding fracture classification. Conclusion The 3D simulation model of acetabular fracture is intuitive, realistic and dynamic and is helpful for clinical work and medical teaching.
