摘　　要：目的:研究外斜位X线片上股骨距的影像特征,探讨外斜位片显示股骨距的临床意义。方法:用成人干燥股骨标本143根,进行外斜45°拍片,对股骨距影像进行分析测量。结果:外斜位和正位显示股骨距阳性率分别为86.5%和29.0%。股骨颈主要抗压力骨小梁总宽度由上向下递减,与股骨距相交于Ward三角下角,此区骨小梁稀疏。次级抗压力骨小梁与股骨距相连为一体。结论:股骨距与主要抗压力骨小梁交界处相对薄弱,是股骨颈骨折的好发部位。次级抗压力骨小梁即股骨距松质骨影像。外斜位X线片可以为临床上显示股骨距特征提供参考。Objective: To study the morphologic characteristics of the femoral calcar on craniocaudal oblique view of 45 degree X-ray films and evaluate the importance of this image technology in clinic practice. Methods: The craniocaudal oblique view of 45 degree roentgenographs were performed in 143 dry thighbones, while the characteristics of the bone trabeculae and the femoral calcar was observed and analyzed. Results: The femoral calcar was observed on the majority of films (87%) and it joined to the main pressureproof bone trabeculae in the lower region of Ward triangle where the mechanics was weakness. Conclusions: The femoral calcar can be shown completely in the craniocaudal oblique view of 45 degree X-ray films and it is a better way in clinic to provide the information of osteoporosis in femur and that conduce to the operation of the upper segment of femur.
