摘　　要：目的:探寻可供临床应用的次髎穴定位取穴及针刺操作方法及先进的测量研究手段。方法:利用CT扫描仪对106例女性进行盆部扫描。将原始图像数据进行三维重建,在三维立体空间中测量次髎穴相关径线、角度,并进行统计分析。结果:髂间距与孔间距存在直线相关性,骶髂距与孔髂距存在直线相关性,据此确定次髎穴的坐标定位点。体重与直刺深度存在直线相关性,根据体重可得出直刺深度。第2骶孔倾斜角度为(30.08±4.26)°,孔深距为(20.13±2.11)mm,从而提出次髎穴斜刺法。结论:CT三维重建模型能够更加准确、合理、科学地进行穴位解剖测量。Objective To determine the location of Ciliao （BL 32） by the help of three-dimensional （3-D） surface reconstruction of computed tomography （CT） so as to provide a reference for clinical application. Methods A total of 106 female volunteer subjects were enrolled in the present study. A GT scanner was used to scan the subjects＇ pelvis, and the collected image data was processed by Dextroscope workstation. The distances and angels of Ciliao（BL 32） in the 3-D space were measured. Results A linear correlation existed between the inter-lilac distance （L 1 ） and sacro-foremen distance （L 2, with the regression equation being Y= 20.219 ＋ 0.25X）, and between the sacro-iliac distance and sacral foremen-lilac distance （with the regression equation being Y= - 14.007 ＋ 0. 446X）, which were used to determine the location of BL 32. A linear correlation also existed be- tween the body weight and the needling depth （with the regression equation being Y= - 18. 893 ＋ 0.988X）. So, the suitably inserted straight depth of acupuncture needle could be determined according to the woman＇s body weight. The oblique angle of the 2nd sacral foremen was （30.08 ± 4.26）°, and the depth of the 2nd sacral foramen was （20. 13±2. 11 ） mm. Conclusion In accordance with the results obtained from CT 3-D reconstruction, oblique needling of an acupuncture needle for Ciliao （BL 32） is highly recommended.
