MORPHOLOGY AND TOPOGRAPHY OF NUTRIENT FORAMINA OF FEMUR

The major blood supply to long bones occurs through nutrient arteries which enter through the nutrient foramina. The knowledge about the morphology and topography of the nutrient foramen is essential in certain surgical procedures like fracture treatment and microvascular bone grafting. The present study analysed the number, position, location and direction of nutrient foramina in fifty adult dry Femur bones. 52 percent showed the presence of single foramen. 46 percent showed double foramina and 2 percent were with absent foramen. Out of the total 72 foramina, 59 foramina were dominant. 80.56 percent foramina were located in the middle one third of the shaft of Femur bone. 41.67 percent were located within the two lips of linea aspera.
