摘要：

目的　观察并测量寰椎侧块滋养孔的临床解剖学参数，为降低寰椎侧块螺钉固定术中血管损伤风险提供参考。方法　随机选取38例正常干燥成人寰椎骨标本，观察寰椎侧块滋养孔（以直径≥1.0 mm为判定界限）的形态、数目、位置；测量滋养孔最大横径、纵径、深度，滋养孔外缘到横突孔内缘之间的距离等。结果　38例寰椎标本中，95%存在滋养孔，42%呈圆形、8%呈横椭圆形、45%呈纵椭圆形；5%无滋养孔；79%左右两侧滋养孔对称，16%不对称。滋养孔最大横径为（2.16±0.86）mm，最大纵径为（2.82±1.03）mm，最大深度为（1.75±0.71）mm，滋养孔外缘到横突孔内缘之间的距离（8.61±1.46）mm，各测量指标左右两侧无显著差异。结论　95%的寰椎左右两侧存在滋养孔，且均位于寰椎侧块的中间区域，椎弓根螺钉通道处；临床寰椎侧块螺钉固定时，螺钉的直径可参考（8.61±1.46）mm；螺钉通道距离寰椎侧块内缘（1.73±0.7）mm。

Abstract:

Objective　To observe and measure the clinical anatomical parameters of atlas lateral mass nutrient foramen, so as to provide a reference for the reduction of vascular injury risk by atlas lateral mass screw fixation.　Methods Thirty-eight normal dry human atlas specimens were randomly selected to observe the shape, number, location and symmetry of the nutrient foramen in the lateral mass of atlas (defined as those with a diameter greater than or equal to 1.0 mm). The maximum transverse diameter, longitudinal diameter, depth, and the distance between the outer edge of the nutrient foramen and the inner edge of the transverse perforation hole were measured.　Results　 In 38 cases, 95% of atlas had nutrient foramen, 42% were round, 8% were transverse ellipse, 45% were longitudinal ellipse, and 5% had no nutrient foramen. About 79% of the sides were symmetrical, and about 16% of the sides were asymmetrical. The maximum transverse diameter of the nutrient foramen was (2.16±0.86) mm, the maximum longitudinal diameter was (2.82±1.03) mm, and the maximum depth of the nutrient foramen was (1.75±0.71) mm. The outer diameter of the nourishing hole was between the inner diameter of the transverse hole. The distance was (8.61±1.46) mm, and there was no significant difference between the left and right sides of each measurement index. Conclusion　There are nourishing holes on the left and right sides of 95% of the atlas. The position is located in the middle of the lateral mass of the atlas, which is in the channel of the pedicle screw. When atlas is fixed, the diameter of the screw can be referenced is (8.61±1.46) mm. The screw channel is located at the inner edge of the atlas lateral mass (1.73±0.7) mm.
