Abstract

Background: The nutrient foramen of Human ulna bone is on the anterior surface of shaft of ulna almost proximal to the mid point and is directed upwards. Nutrient foramen permits the passage of the branch of anterior interosseous artery. Methods: The present study was conducted on 70 dry human ulna bones of unknown sex and age obtained from Government 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 two nutrient foramen on right side while one foramen on all the left side. The location of nutrient foramen in right and left ulna bones was 72% in the middle one third, 18% in upper third and 8% at the junction of upper and middle one third. The position of nutrient foramen was 80% on the anterior surface, 11% on the Interosseous border and 7% on the anterior border. All the foramen were directed upwards Conclusion: The study of nutrient foramen is of utmost importance to the forensic experts as in determining the length of ulna and to the orthopaedicians for deciding different treatment modalities in case of fractures of shaft of ulna so as to prevent non-union or avascular necrosis and also helpful for highly specialised surgical procedures like vascularised bone grafting involving microsurgery.
