Establishment of a digital Evans-Jensen classification model of femoral intertrochanteric fracture / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To establish a digitized Evans-Jensen classification model of femoral intertrochanteric fracture.</p><p><b>METHODS</b>The hip of a healthy male volunteer was examined with 64-slice spiral CT, and the data were processed using Mimics 10.01 software to reconstruct the proximal femur model. According to Evans-Jensen classification criteria of femoral intertrochanteric fracture, each type of fracture model was simulated. Five orthopedic surgeons and 10 medical students undertook the preliminary evaluation of the digital fracture model.</p><p><b>RESULTS</b>The digital fracture model is intuitive, three-dimensional, and realistic with good visual effect. The fracture could be observed and charted from optional direction and angle. The corresponding animation allowed 360 degrees rotation. Evaluation by the 4 orthopedic surgeons and 10 medical students confirmed that the digital fracture model was intuitive and easy to understand.</p><p><b>CONCLUSION</b>The digital model of femoral intertrochanteric fracture is intuitive, three-dimensional, realistic and dynamic, and may help in clinical practice and medical teaching.</p>
