本研究的目的是(1)应用CT血管成像技术评价闭孔动脉在闭孔孔处的解剖变异和位置，以及(2)通过术后CT图像评价髋臼旋转截骨术中耻骨截骨部位，以评估闭孔动脉与耻骨截骨部位的关系。方法对98例日本患者196个髋关节进行了AIM(1)和38例髋臼旋转截骨术(2)。结果闭孔动脉吻合的发生率为14.3%，(2)闭孔动脉吻合的发生率为14.3%；(2)闭孔动脉吻合的发生率为14.3%闭孔动脉离耻骨上支和截骨点较近。结论闭孔动脉变异的髋臼旋转截骨术应慎重。
PurposeThe aims of this study were (1) to evaluate the anatomical variations and locations of the obturator artery at the obturator foramen using computed tomographic (CT) angiography images and (2) to evaluate the pubic osteotomy site in rotational acetabular osteotomy using postoperative CT images in order to assess the relationship between the obturator artery and the pubic osteotomy site.MethodsWe examined a total of 196 hips in 98 consecutive Japanese patients for aim (1), and 38 consecutive patients who underwent rotational acetabular osteotomy for aim (2).ResultsThe prevalence of arterial anastomosis of the obturator artery (corona mortis) was 14.3 %, with the obturator artery being located closer to the superior pubic ramus and the osteotomy site in these subjects.ConclusionsExtensive care should be taken during rotational acetabular osteotomy in patients showing variations of the obturator artery with corona mortis.
