摘要
目的探讨建立股骨转子间骨折Evans-Jensen分类的数字化仿真模型的方法及意义。方法对1名健康男性志愿者行髋部64排螺旋CT扫描,所得数据应用Mimics10.01软件处理,重建出股骨近端模型,依照股骨转子间骨折Evans-Jensen分类的标准模拟出各型骨折,对模型进行截图保存,并输出影片模式。5名骨科医师和10名医学生对数字骨折模型给予初步评价。结果股骨转子间骨折Evans-Jensen分类数字化仿真模型直观、立体、逼真,具有良好的视觉效果,可以从任意的方位和角度观察和截图,相对应的影片可以360°旋转观看骨折情况。4名骨科医师和10名医学生认为三维数字骨折模型更加直观、容易理解。结论股骨转子间骨折Evans-Jensen分类的数字化模型具有直观、立体、逼真、动态等特点,有利于临床工作及医学教学。
Objective To establish a digitized Evans-Jensen classification model of femoral intertrochanteric fracture. Methods 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. Results 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° rotation. Evaluation by the 4 orthopedic surgeons and 10 medical students confirmed that the digital fracture model was intuitive and easy to understand. Conclusion The digital model of femoral intertrochanteric fracture is intuitive, three-dimensional, realistic and dynamic, and may help in clinical practice and medical teaching.
