Introduction: Femur is highly rich in blood supply by various surrounding arteries of lower limb. The arteries of shaft (diaphysis) are known as nutrient arteries. The purpose of this study was to find the number, site and direction of nutrient foramina over the shaft of the femur which will be helpful the surgeons for treatment planning. Methodology: Unpaired 102 dry femurs, 50 of female (27 right and 23 left) and 52 of male (27 right and 25 left) devoid of any gross pathology were used to find the number and site of nutrient foramina of femur from Department of Anatomy, Govt. Medical College, Bhavnagar in year 2005. They were examined by magnifying glass and hypodermic deedless. The data were statistically analyzed. Result: 1. Number of foramina: Out 102 bones - 2 bones have no foramina, 44 have 1 foramina, 41 have 2 foraminas, 10 have 3 foramina, 3 have 4 foramina, 1 has 5 and 1 has 6 foramina. 2. Site: 80.95% of foramina are in the middle 1/3 of the shaft. No nutrient foramina found in upper and lower 1/6 of the femur. The mean of femoral foraminal index is 49.88. 3. All foramina were directed upwards towards the upper end of femur. Conclusion: The data received in this study were analyzed and compared with previous studies. The findings in this study will be helpful during various surgeries over femur like fracture treatment, bone grafting and vascular surgeries of lower limb. [Ankur Z NJIRM 2017; 8(4):38-40]
