Morphometric Study in the Variations of Number, Position and Direction of Nutrient Foramen in the Clavicle

Abstract

Introduction: 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.Methodology: This study was conducted in department of Anatomy, CIMS Medical college, Bilaspur, Chattisgarh. In this study we included total 60 dried human clavicle bones. Duration of study was over a period of one year.Results: This study revealed the different number, position & direction of nutrient foramina of clavicle. It was found that in 65 % bone one foramen was present, while two nutrient foramen was present in 26.7% clavicle bones & three nutrient foramen in 8.4% clavicle bones.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.
