The humerus is the longest bone of the upper extremity and is supplied by the nutrient artery (NA). NA reaches the bone via the nutrient foramen (NF) and, like other nutrient arteries, is important in bone development during the prenatal and postnatal periods. Understanding the location of NF is critical as it may help optimize invasive procedures. We aimed to analyze the topographic location of NF in the Turkish population and present its possible clinical significance. 176 (85 right, 91 left) Turkish dry adult human humeruses were examined in the Department of Anatomy, Istanbul University, Istanbul Faculty of Medicine. NF in each bone was detected with a 0.25 X 30 mm acupuncture needle and smaller ones were excluded from evaluation. The number, direction and topography of NFs on the humerus were determined, then morphometric measurements were made using a digital caliper. Humerus length (HL), the distance of NF to the top of the humeral head (CH-NF) and the shortest distance to the medial epicondyle (ME-NF) were measured. Foraminal index (FI) was calculated and the location of NF was classified into three groups according to the results. The mean HL was found to be 31.13+2.71 cm. Single NF was found in 151 (85.8%) of 176 bones and double NF in 22 (12.5%). NF was not found in 3 (1.7%) of the bones. According to the results, NFs were most frequently localized on the anteromedial surface and middle 1/3 of the bone at a rate of 59.4%. Although most of our findings support the literature, in our study, unlike previous studies, each morphometric value was documented separately for humerus with single NF or double NF. In this context, the findings we obtained may enable surgeons to follow a more effective strategy during the operation by taking into account the location of NFs.
