摘　　要：目的:探讨骶骨解剖参数CT测量了解新型骶骨蝶形钢板DenisI区安全置钉通道。方法:回顾性分析2020年1月至2020年6月正常成年骶骨CT资料101例,女49例,男52例,年龄(49.11±15.02)岁。重建骶骨三维模型,根据所需测量平面重新分割三维模型,并进行数据测量及统计分析。结果:骶骨上关节突下缘至S2骶后孔下缘的竖直距离为(42.55±4.73) mm;S_(1)、S_(2)、S_(3)孔平面骶外侧嵴至骶髂关节面的水平距离依次为(19.09±3.07) mm、(15.34±2.69) mm、(8.29±2.48) mm;S_(1)孔平面由骶外侧嵴向前进钉,内侧角、外侧角为(7.49±7.49)°、(24.07±4.89)°;S_(2)孔平面内侧角、外侧角为(-3.10±8.95)°、(24.95±5.74)°。不同性别间除S_(1)水平距离、S_(1)内侧角外其余差异均有统计学意义,年龄与所有数据均无相关性。结论:新型骶骨蝶形钢板在Denis I区有足够的安全置钉范围;成年人骶骨形态间存在差异,差异主要与性别相关而与年龄无关。Objective:To investigate the CT measurement of sacral anatomical parameters and understand the safe nail placement channel of Denis I area with a new sacral butterfly plate.Methods:The CT data of 101 normal adult sacrum from January 2020 to June 2020 were retrospectively analyzed,including 49 females and 52 males,aged(49.11±15.02) years old.Firstly,the three-dimensional model of sacrum was reconstruct,the three-dimensional model according to the plane was re segment to be measured,and data measurement and statistical analysis were carried out.Results:The vertical distance from the lower edge of superior sacral articular process to the lower edge of S2 posterior sacral foramen was(42.55±4.73) mm;The horizontal distance from the lateral sacral crest of S_(1),S_(2) and S_(3) hole plane to the sacroiliac joint surface was(19.09±3.07) mm,(15.34±2.69) mm and(8.29±2.48) mm respectively;The plane of S1 hole moves forward from the lateral sacral ridge,the inner and outer angles are(7.49±7.49)° and(24.07±4.89)° respectively;The inside and outside angles of S2 hole plane are(-3.10±8.95)° and(24.95±5.74)° respectively.There were significant differences between different genders except S_(1) horizontal distance and S_(1) medial angle,and there was no correlation between age and all data.Conclusion:The new sacral butterfly plate has enough safe nail placement range in Denis Ⅰ area;There are differences in sacral morphology among adults.The differences are mainly related to gender but not age.
