The largest and longest bone in the upper limb is the humerus. The nutrient foramen is an aperture in the bone's shaft that permits blood vessels to get to the bone's medullary cavity for nutrient and growth. The long bones' nutrient foramina have been the subject of numerous published research. Since the literature has not yet established a palpable landmark for the nutrient foramina, the purpose of this study was to characterize the nutrient foramen in dry adult humeri in terms of their numbers and location.
Methods: The study comprised all the humerii (not necessarily paired and those of unknown age and sex) from the university of the Aam Admi Party's medical colleges. The length of the humerus, the number of nutrient foramen, the size of the nutrient foramen, the location of the nutrient foramen in regard to the surfaces and the zones, and the distance of the nutrient foramen from the midpoint of the humerus were all observed. All the data were recorded, and the percentage, mean, range, and standard deviation were computed as part of the statistical analysis.
Results: In our study we examined 147 humeri. Among 147 examined humeri there were 82 right humerus and 65 left humeri. The number of single nutrient foramen was most commonly recorded among examined humerus (78.91%). The examination of humerus for location of nutrient foramen based on surface showed that more than four fifth of nutrient foramen were located on anteromedial surface (83.67%). The mean total length of humerus examined was 269.75±22.53 mm and the mean distance from of nutrient foramen from proximal end of humerus was 151.93±17.57 and calculated foraminal Index (FI) was 55.36%.
Conclusion: When performing various surgical procedures on the humerus, such as treating fractures, bone repair, bone grafting, micro-surgical bone transplantation, in numerous fractures, and during extensive periosteal stripping, orthopaedic surgeons must have a thorough understanding of the anatomy of the number, location, and direction of the nutrient foramina of the humerus in order to minimise damage to the nutrient artery of the humerus.

Nutrient artery enters the bone obliquely through the nutrient foramen, which is directed away as a rule from the growing end. Aim & Objective- To locate and describe as well as to observe any variation in the number and position of nutrient foramen of fibulae. Material and Methods- Present study was done on 107 human dried fibulae collected from Krishna Mohan Medical College & Hospital, Mathura. In this study we used magnified hand lens and a thin stiff wire to confirm the number and direction of nutrient foramen. Results- Out of 107 fibulae examined, 88(82.24%) showed a single foramen while 17(15.88%) possessed double foramina and 2(1.86%) are having no nutrient foramen of the total 122 foramina, 115(94.26%) existed in the middle third, 5(4.09%) in upper third and 2(1.63%) were in the lower third of the shaft. Conclusion- This study has provided information on the morphology and topography of nutrient foramen of fibulae. This knowledge of nutrient foramen is useful in certain surgical procedure to preserve circulation

Background: The nutrient foramina of the clavicle have extensive clinical importance as these are involved in the repair of clavicular fracture. Therefore, the aim of the present study was to evaluate the morphometry and topography of nutrient foramen in clavicle.
Material and Methods: This study was conducted in department of Anatomy. In this study we were included total 60 dried human clavicle bones. The duration of study was over a period of one year.
Results: The result of this study was revealed that one foramen was present in 65% bone. While, two nutrient foramen present in 26.7% clavicle bones & three nutrient foramen present in 8.4% clavicle bone. Which were found macroscopically.
Conclusion: This study concludes that from all the findings that the nutrient artery should be preserved carefully while doing surgical procedure like internal fixation and vascularised bone graft.
