OBSERVATIONAL STUDY TO LOCATE NUTRIENT FORAMINA INLONG BONES OF UPPER EXTREMITY IN WESTERN POPULATION

Abstract

Introduction: The nutrient foramina is a opening that carry the nutrient arteries and the
peripheral nerves on the shaft of long bones. Long bones receive most of the interosseous blood
supply from the nutrient arteries, and sometimes through the periosteal vessels. The aim of the
study was to evaluate the number, position and direction of the nutrient foramina in the
humerus, radius and uulna of dry bones of western rajasthan origion and correlate the findings
clinically.
Material and Methods: Humerus, radius and ulna 100 each were taken from the department of
Anatomy,Dr S.N. Medical College,Jodhpur and studied for the location ,direction and number of
Nutrient foramina.Inclusion of these bones were irrespective of the gender and age. Sliding
caliper and osteometric board,magnifying glass were used for measuring these parameters
Result: It were found that the direction of nutrient foramina is opposite to the growing end
i.e.seek the elbow. Double nutrient foramina were found in (17% ), (18%) cases of humerus and
radius respectively.The nutrient foramen in( 100%) humerus was found in middle 1/3rd. The
nutrient foramen in (90% )radius was found in middle 1/3rd and ( 10%) in upper 1/3rd.in (85 %)
Ulna the nutrient foramina was found in middle1/3rd and( 15%) in upper 1/3.
Conclusion
This anatomical study of nutrient foramina in shaft study of long bones is of paramount
importance in medico- legal aspect and also important in surgical procedures like bone grafting
and microsurgical bone transplantation.
