【摘要】：目的通过骨折地图技术,明确股骨近端外侧壁的骨折特征,为临床及生物力学研究提供参考数据。方法采集96例股骨转子间骨折的CT数据,进行分割建模、虚拟复位。其中有56例发生外侧壁骨折,测量其外侧壁及骨折区宽度、高度、面积,骨折线走行等参数,并在3D重建模型上绘制骨折特征地图。结果 96例患者中56例有外侧壁骨折,其中A2型71.4%(40例),外侧壁骨折块平均宽度(10.1±6.0)mm,高度(23.1±11.3)mm,面积(158.5±105.2)mm2,占外侧壁面积(12.1±8.1)%,骨折线与水平面成角(64.6±14.5)°;A3型28.6%(16例),外侧壁骨折块平均宽度(26.0±7.0)mm,高度(38.8±11.7)mm,面积(860.1±357.0)mm2,占外侧壁面积(64.5±25.9)%,骨折线与水平面成角(30.2±39.6)°。结论不同类型转子间骨折的外侧壁特征有明显差异,通过骨折地图技术可直观展现骨折信息,可为制作转子间骨折模型及临床治疗提供参考。
[Abstract]:Objective to identify the fracture characteristics of proximal lateral wall of femur by fracture map technique, and to provide reference data for clinical and biomechanical research. Methods CT data of 96 cases of femoral intertrochanteric fracture were collected. There were 56 cases of lateral wall fracture. The width, height, area and fracture line of lateral wall and fracture area were measured, and the characteristic map of fracture was drawn on 3D reconstruction model. Results 56 of 96 patients had lateral wall fractures. The average width, height and area of the lateral wall fracture were (10.1 卤6.0) mm, (23.1 卤11.3) mm and (158.5 卤105.2) mm, respectively. The lateral wall area was (12.1 卤8.1) mm. The fracture line was (64.6 卤14.5) 掳A3 type 28.6% (16 cases). The average width, height, and area of the lateral wall fracture mass were (26.0 卤7.0) mm, (38.8 卤11.7) mm, (860.1 卤357.0) mm, respectively, and the lateral wall area was (64.5 卤25.9) mm, the average width of the lateral wall was (26.0 卤7.0) mm, the height was (860.1 卤357.0) mm, the area was (860.1 卤357.0) mm, and the lateral wall area was (64.5 卤25.9) mm. The angle between the broken line and the horizontal plane was (30.2 卤39.6) 掳. Conclusion the characteristics of lateral wall of different types of intertrochanteric fractures are obviously different. Fracture information can be displayed intuitively by fracture map technology, which can provide reference for making intertrochanteric fracture model and clinical treatment.
