Abstract

Background- The nutrient artery, which enters the bone shaft through the nutrient foramen, is the principal source of the blood to a long bone, particularly during its growth period in the embryo and fetus, as well as during early phases of ossification during childhood. From recent hypothesis it has been confirmed that vascularized bone and joint allograft survival depends strongly on the blood supply of bone. Objective- the present study was conducted to analyze nutrient foramen in 100 adult human Clavicle of North Indian Origin. The number and position of nutrient foramen were observed and their distribution over bone length was determined by Foramina Index. Direction of nutrient canal was also observed. Result & Conclusion- The study showed 70% clavicles with single nutrient foramen 20% of clavicles with double foramen and 10% of clavicles with more than two foramen. 69.8% of clavicles had foramen over inferior surface while 30% of clavicles had foramen on posterior surface. The range of foramina index for dominant foramen was between 30% to 76.4% with 61.1% of dominant foramen located in middle one third of bone length. The nutrient canal was directed towards acromial end.
