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。
Objective Using fracture map technology to study characteristics of the proximal femoral wall fracture, providing reference data for clinical and biomechanical studies. Method CT data from 96 patients with trochanteric fracture were collected. In the cases with proximal femoral lateral wall fracture, the lateral wall and fracture area（width, height, area, fracture line direction） were measured and fracture mapping was created. Result In 96 patients, 56 had lateral wall fractures. 71.4% were A2 type（40cases）. The average width of fractures area was（10.1±6.0） mm, the height was（23.1±11.3） mm, and the area was（158.5±105.2） mm^2, accounting for（12.1±8.1）%. The fracture line was（64.6±14.5） ° with the horizontal plane. 28.6% were A3 type（16 cases）. The average width of fracture area was（26.0 ± 7.0） mm, height was（38.8±11.7） mm, and area was（860.1±357.0） mm^2, accounting for（64.5±25.9）%. The angle of fracture line was（30.2 ± 39.6） °. Conclusion Characteristics of different types of trochanteric fractures of the lateral wall are significantly different. The fracture map can directly display fracture information. The results of this study can provide a reference for the standard fracture model in clinical and experimental study.
