Abstract

Background: 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.
