All nutrient vessels arose from the iliolumbar artery, forming a breakthrough-anastomosis to the superior gluteal artery. Two branches were seen in 57.6% on the right and 61.2% on the left side, constituting the most prevalent branching pattern. Three branches were seen in a third for each side. One or four branches were seen in 3\u20134.5% for both sides. A prominent branching pattern we coined \u201ccentral-vessel-convolute\u201d (CVC) at the central part of the ilium was seen in 75% on either side. Perivascular fatty areas were found in 25% of cases, and in 3.7\u20132.4% adjacent bone-marrow edema was observed.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Prominent nutrient vessels in the ilium are seen in almost all individuals, the majority exhibiting a specific CVC-pattern.
