Clinical Correlation Of Nutrient Foramen Of Dry Human Ulna Bones In Jammu Region

ABSTRACT

Background: The nutrient foramen of Human ulna bone is on the anterior surface of shaft of ulna almost proximalto the mid point and is directed upwards. Nutrient foramen permits the passage of the branch of anteriorinterosseous artery.Methods: The present study was conducted on 70 dry human ulna bones of unknown sex and age obtained fromGovernment Medical College Jammu. The Ulna bones were observed macroscopically for nutrient foramen.Results: In our study we observed that only 2 bones were without nutrient foramen and two of the bones with twonutrient foramen on right side while one foramen on all the left side. The location of nutrient foramen in right andleft ulna bones was 72% in the middle one third, 18% in upper third and 8% at the junction of upper and middleone third. The position of nutrient foramen was 80% on the anterior surface, 11% on the Interosseous border and7% on the anterior border. All the foramen were directed upwardsConclusion: The study of nutrient foramen is of utmost importance to the forensic experts as in determining thelength of ulna and to the orthopaedicians for deciding different treatment modalities in case of fractures of shaftof ulna so as to prevent non-union or avascular necrosis and also helpful for highly specialised surgicalprocedures like vascularised bone grafting involving microsurgery
