Dr. K. R. S. Prasad Rao, Dr. V. Janaki

Abstract :

 INTRODUCTION: The clavicle (collar bone) is an unusual long bone which has many unique emyologic features The main aim of this study is to find variation in number and position of nutrient foramen of the human clavicle which enlightens the operating surgeon in the free vascularised bone grafts and in microsurgical vascularised bone transplantation. MATERIAL AND METHODS: 58 (32 on left side & 26 on right side)adult dry human clavicles collected in the department of Anatomy, irrespective of sex and age were studied macroscopically with help of magnifying glasses the data were collected and morphologically analyzed. OBSERVATIONS AND RESULTS: neurovascular foramina were observed in all clavicles . The foramen was single in 28 (48.3%) clavicles, double in 19 cases (32.7%) and 5 clavicles (8.3%) had 3 foramina ,6 clavicles had more than 3 foramina (10.3%). In 51 clavicles (89%), the foramen was observed in the medial 2/3rd of length of the bone . In 7 clavicles (11%), the foramen was in the lateral 1/3 of length of the bone . The average distance of the foramen from the sternal end was 6.23cm. In 29 (50%) of the clavicles, the foramen was on the posterior surface . Whereas 24 (40.3%)clavicles, the foramen was observed on the inferior surface . In 4 clavicles (6.9%) had the foramen at its superior surface .only in 1 clavicle(2.7%) nutrient foramen was present on anterior surface. CONCLUSION: The present study showing the presence of nutrient foramen in the posterior surface in significant number of cases contradicts the classical textbook presentation as on in its inferior surface. Knowledge of the localization of nutrient foramina can be useful in certain surgical procedures to preserve the circulation to bone
