Assessment of variations in number, position and direction of nutrient foramina of clavicle

Abstract

Background: Human beings are bestowed with the power of bipedal locomotion; the clavicle serves as a strut that permits the upper limb to freely move away from the chest wall. The present study was conducted to assess variations in the number, position, and direction of nutrient foramina in the clavicle 
Materials & Methods: 54 dried adult human clavicles were taken. The foraminal distance from the sternal end (DNF) and the total length of the clavicle (TL) were measured. The foramen index (FI): FI = (DNF/TL) ×100, DNF = distance of nutrient foramen from the proximal end (sternal end) of the clavicle, TL = total length of clavicle, was calculated.
