Background: The Femur bone is a vascular structure with unique features in its blood supply via numerous foramina located over its different segments, being named as nutrient foramina. Among vascular foramina, nutrient foramen is an important one which gives way to the nutrient artery.
Methods: This study was conducted using descriptive cross sectional based of the study designs & it will include 50 femur bones of different cadaveric specimen’s which will be obtained from the osteology section of our Department of Anatomy. All bones belonged to Sudanese cadavers, the age and gender of which are not determined. All the bones will macroscopically observe for the number, location and direction of the nutrient foramina. A magnifying lens were used to observe the foramina. The nutrient foramina were identified by the well-marked, often slightly raised, edge at the commencement of the canal.
Results: The nutrient foramina of 50 dry adult human Femora, 38 Femora had single nutrient foramen, 9 had two nutrient foramina and 3had absent nutrient foramina. Location of 28 of single nutrient foramina were located at the junction of upper and middle 1/3rd of the femur, 4 of single nutrient foramina were located at the junction of middle and lower 1/3rd of the femur, 6 of single nutrient foramina were located in middle half of the length of the femur, 5 of double  nutrient foramina were located in upper and middle position and 4 of double nutrient foramina located at upper and lower position .according to surface relationship ,37 of single nutrient foramen located at posterior surface and 1 at medial surface .7 of double nutrient foramina located at posterior surface and 3at medial surface   all nutrient foramina were seen to be directed upwards.
