Introduction: The clavicle is a modified long bone. It is the most important bone for transmission of weight from upper limb to the axial skeleton. It supports the shoulder so that the arm can swing clearly away from the trunk.
Materials and Methods: The study included 102 adult clavicles 52 right sides and 52 left side which were obtained from the department of the Anatomy Dr. S.N. Medical College Jodhpur. The age and sex of the clavicles were not determined. All the bones were grossly observed for the number, location and direction of the nutrient foramina. The data were collected and morphologically analysed.
Results: In our Present study Nutrient foramina were present in 50 clavicles (Right) and 44 clavicles (left). Out of which single foramina in 41 clavicles (Right) and 36 clavicles (Left), double foramina in 9 clavicles (Right) and 6 clavicles (left) and three foramina in 2 clavicles (Left). Absence of nutrient foramina were found in 2 clavicles (Right) and 8 clavicles (Left).
Maximum number was present in the medial 2/3 and on the posterior surface of 46 bones (Right) and 34 Bones (Left). All foramina were directed towards the acromial end.
Conclusion: The knowledge of nutrient foramina in clavicles is important for surgical procedures such as bone grafting and in microsurgical vascularized bone transplantation.
