Background: Clavicle is a curved modified long bone placed horizontally at the root of neck.It transmits the weight of upper limb to the axial skeleton.The aim of this study is to determine position, number, and direction of nutrient foramen.Material method: The present study was conducted on 50 (25 right and 25 left) dried clavicles, in the department of Anatomy, Forensic medicine, Narayan Medical College, Jamuhar, Sasaram, Bihar.Result: The nutrient foramen was present in all the clavicles.One nutrient foramen was present in 70%, two in 24% and three in 6% of clavicles.Predominant position of nutrient foramen was on the posterior surface (55.88%) and predominant location was in the middle one third (70.58%) of clavicles.Direction of all the nutrient foramina were towards the acromial end. Conclusion:The study of number, position, location and direction of nutrient foramina of clavicles are useful to preserve the arterial supply during surgical procedure like internal fixation and vascularised bone graft.
