Introduction Nutrient foramina are entry points of nutrient arteries in bones and form important landmarks on human bones. Understanding the nutrient foramina is critical to surgical practice. An insult to the nutrient foramina leads to devascularization of bone. The number, position, patency and direction of nutrient foramina are important in various surgical procedures and vary with race, ethnicity and geographical areas highlighting the importance of this study. The objective of the present study was to describe the number, position, direction, size, and foraminal index of nutrient foramen in the human adult femurs. Its importance in orthopaedic procedures has inspired us to undertake this study Materials and methods This study was conducted on 100 adult dry femur bones (50 right and 50 left). All the important parameters were studied using osteometric board, vernier calipers, and needles of different gauges. Results: Mean distance of nutrient foramen from upper end was 18.09 cms. The most common location of NF was on lateral surface 58.8%. In 71% femur only one NF was seen, while 25% had two NF, 1% femur had three NF and 3% femur had no NFs. In 64.5% femur big size or dominant NFs were seen in present study. Results 56% of femurs were right-sided and single foramina was seen in 75% of bones. In two- thirds of bones, nutrient foramina were found in upper two-thirds of femur and most common site of nutrient foramina was medial lip of Linea aspera. The direction of nutrient foramina was away from growing end in 95% of bones and in same percentage of bones nutrient foramina were found patent. The mean foraminal index for the femur bones was 40.8 with SD of 12.62 and mean length was 38.9cm with SD of 2.5cm. Conclusion The study of nutrient foramina in dry adult femur bones reveals important aspects of bone vascularization and can provide insights into bone health and development. By examining the number, size, and location of nutrient foramina, researchers can better understand the biology of bone growth, aging, and pathology. This knowledge is essential not only for anatomical and forensic studies but also for clinical applications such as orthopedics and surgery.
