Abstract
PURPOSE: The 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. METHODS: We 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). RESULTS: The 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. CONCLUSIONS: Extensive care should be taken during rotational acetabular osteotomy in patients showing variations of the obturator artery with corona mortis.
