Nutrient artery is the main source of blood supply to the long bones. As in 1% cases nutrient foramina and nutrient artery may be positioned in unusual positions, therefore, knowledge about various other positions of nutrient foramina is important for various operative and diagnostic prospective. Aims and objectives: The presence, position, number, direction, and distances of nutrient foramina from the various landmarks on the bone have importance in various orthopedic procedures as nutrient artery has a pivotal role in the growth and development of the long bones. The present study was done to know the prevalence of accessory nutrient foramina and its position in human ulna and radius. Materials and methods: In this study, 100 ulna and 100 radius bones were studied in the Department of Anatomy, Sarojini Naidu Medical College, Agra, Uttar Pradesh, India, for the presence of accessory nutrient foramina and its position from the proximal epiphysis of the long bones. Results: Accessory nutrient foramina was present in 6% of radius bones and 11% of ulna bones. Middle third part among radius bones and upper third part among ulna bones were most common positions of accessary nutrient foramina. Conclusion: This study provides precise knowledge of accessory nutrient foramen in long bones. Knowledge of accessory nutrient foramina prevalence and position is of immense importance for orthopedician in treating complicated fractures of long bones. The location of accessory nutrient foramen is also important in various other orthopedic procedures like bone grafts, tumor resection, correction of congenital pseudoarthrosis, and many other microvascular surgeries.
