“…In many previous studies, it has been stated that FN is located mostly on the posterior surface [6,11,14,16,21,22]. However, there are also studies showing that the FN is most often in the inferior position, as in our study [20,24]. Similar to our study, some studies show that the number of FNs on the posterior and inferior sides are close to each other [12,24].…”

“…However, FN with Type 1 localization was not observed as in the study of Cihan et al [6]. Many previous studies have shown similar results to our ndings and have shown that the most common localization type is Type 2 localization [6, 15,16,22,24]. The FI value above 50 indicates that the FN is farther from the proximal (sternal) end and closer to the distal (acromial) end.…”

“…In classical texts, it is stated that the FN is located on the inferior surface of the clavicle and lateral to the subclavian groove [26]. However, previous studies have shown that FN can be found not only on the inferior surface of the clavicle but also on other surfaces [6,11,16,20,24]. In our study, the FN was most frequently found on the inferior surface (57 cases − 48%) and the second most frequently on the posterior surface (52 cases − 44%).…”

“…There is a subclavian groove on the inferior surface of the clavicle, and there is usually a foramen nutricium (FN) directed outward laterally to this groove [26]. FN is a hole in the body of long bones that allows the nutrient artery, which is of vital importance for bone development, especially in intrauterine life, to reach the bone tissue [6, 15,24,26]. A fascicle of the supraclavicular nerve also passes through the FN on the clavicle along with the nutrient artery [12,14].…”

“…However, in the study conducted by Havet et al [9], an FN marked by a branch of the suprascapular artery was detected on the inferior surface of the clavicle. On the other hand, many studies have been conducted on the morphometric features, localization, position and variations of FN on the clavicle [7,14,15,21,24,27]. Likewise, there are many studies on the morphological and morphometric features of the clavicle [2-4, 19, 28].…”

Purpose The aim of this study was to analyze the relationship between the location and number of foramen nutricium (FN) on the clavicle and other clavicular parameters. Methods This study was performed on 86 dry clavicles (46 left, 40 right). Morphometric measurements were measured with a digital caliper. Results The most of the bones had a single FN. There was no FN on 3 bones, and there were 4 FN on 2 bones. The right-left side differences in the sagittal and vertical thickness of the sternal end (STs and VTs, respectively), the distance of the FN to the sternal end and the posterior edge (DFS and DFpost, respectively) and the foraminal index (FI) were statistically significant. There was a positive correlation between some FN parameters and clavicular parameters. FN was mostly located in Type 2 and was mostly located in the inferior face. The bones without FN were longer and thicker. The vertical and sagittal thickness of the thinnest point of the clavicle was greater in bones with 4 FN. Conclusion It was observed that there was a relationship between the number and location of the FN and its morphometric features, and many clavicular parameters. Knowing the location of the FN on the clavicle is important for protecting the nutrient artery in orthopedic surgery applications.
