目的 确定骨盆 X线片泪痕影像的解剖学结构并探讨其临床意义。方法 制作一完整干燥成人骨盆 ,在 X线投照下找出构成泪痕的结构部位 ;拍摄 1 97名正常成人正位骨盆片 ,测量相关数据。结果 构成泪痕下端弧型影为髋臼切迹前端的柱状骨皮质重叠影 ,泪痕外侧脚为髋臼切迹处向髂前上棘方向延伸之骨皮质重叠影 ,内侧脚则是由构成外侧脚所对应盆面骨皮质重叠影形成。结论 构成泪痕的结构为髋臼窝前下方处的内、外骨皮质影。泪痕宽与髋臼窝的前下方厚度有关 ,与髋臼窝底的厚度无关。泪痕宽及泪痕外侧脚与股骨头下端处之髋关节间隙 ,在同性的左、右侧间无显著差异 ,但却有显著的性别差
Objective To determine the anatomy of pelvic radiology and its clinical significance. Methods A complete dry adult pelvis was made. X-ray castings were used to identify the structural parts that formed the tear marks. A total of 1 97 normal adult pelvis were taken to measure the data. The results of the formation of the lower end of the arc tear shadow acetabular notch forearm columnar cortical overlap, tear the lateral foot acetabulum notch at the anterior superior iliac spine extending cortical overlap, the medial foot is constituted by the lateral foot Corresponding to the pelvis cortex overlapping shadow into. Conclusion The structure of the tear marks is the medial and lateral cortical shadow of the anterior inferior acetabulum. The width of the tear is related to the thickness of the anterior and inferior acetabular fossa, regardless of the thickness of the bottom of the acetabulum. There was no significant difference between the left and right sides of the same sex in the width of the tear and the gap between the lateral foot of the tear and the lower end of the femoral head, but there was a significant gender difference
