Abstract : Femur bone is longest and strongest bone of human body supply by nutrient vessels of variable numbers, courses and sites of entrances and exits along with perosteal vessels, metaphyseal vessels and epiphyseal vessels. Knowledge of this helpful to surgeons, orthopaedic surgeons during surgical intervention; and anatomy teachers and students during routine study. This knowledge help orthopaedic surgeons to determine part of femur bone necrosed when nutrient arteries damaged. Determine number of nutrient foramina and their distance from the tip the greater trochanter. Clear, clean and unbroken 50 dry femur bones were randomly selected, examined properly and numbers, directions and distances of locations of nutrient foramina from tips of greater trochanters measured with measure tap, noted, analysed and correlated. 88 nutrient foramina found on 50 dry femur bones, 76(86.36%) nutrient foramina on linea aspera, 88(100%) directed upwards, on 18(36%) femur bones 1 nutrient foramen, on 28(56%) femur bones 2 nutrient foramina, on 2(4%) femur bones 3 nutrient foramina, on 2(4%) femur bones 4 nutrient foramina found. When no considerance of how many nutrient foramen present on femur bone, Nutrient foramen usually 88(100%) located at a distance of 10-28 cm and most commonly 20(22.8%) located at a distance of 12-14 cm from tip of greater trochanter of femur bone. Nutrient foramina most commonly located on linea aspera and directed upwards. Surgeons and orthopaedic surgeons have knowledge of nutrient vessels to prevent damage to them during surgical intervention..
