Abstract Fractures of the humerus are common on the midshaft of the bone, often causing injury to the nutrient artery.Successful fracture repair and healing requires preservation of the blood supply to the long bones which is conveyed through the nutrient foramina (NF).The topography of long bone NF varies in different populations.These variations
