The objective of the current study is to establish the number, location, orientation, and foraminal index of nutritional foramen. A bone in the upper limb known as the clavicle transmits body weight to the axial skeleton. The primary nutritional artery can pass via one nutrition foramen, which is often located on the shaft of the clavicle, distant from the growing end. In joint allograft and bone grafting surgeries, the vascularized clavicle is frequently employed. The current investigation involved 62 clavicles of unknown age and sex, of which 34 belonged to the right side and 28 to the left. The bones were taken from the Department of Anatomy and Forensic Medicine Museum at Bhubaneswar, India’s IMS and SUM Hospital. The quantity, position, and direction of the nutrient foramina were recorded and compared to the results of the previous authors’ research. Hughes’ formula was used to obtain the mean foramen index. In 62 bones, a total of 92 nutritional foramina were found. Single foramina were found in 42 of them (67.74%) and double foramina in 12 of them (19.35 percent ). In eight (12.89 percent) clavicles, there were more than two nutritional foramina. There were more foramina (76%) on the posterior surface than on the inferior surface (24 percent ). The central third of the clavicle included 65.21 percent of the foramina. All are turned away from the bone’s developing end. According to our research, the mean foramen index was 53.80 and the foramen’s average distance from the sternal end was 67.9mm. In conclusion, nutritional foramina must be understood in order to do vascularized bone grafts, internal fixation implantation, and microsurgical vascularized bone transplantation. Additionally, it preserves vascular supply throughout radiation therapy. The findings will also provide biomedical engineers with inspiration for creating the clavicle bone model. The vascularity during radiation therapy also requires an understanding of the nutritional foramina.
