COLLIPAL, Erika et al. Diaphyseal Nutrient Foramina in the Femur, Tibia and Fibula Bones. Int. J. Morphol. [online]. 2007, vol.25, n.2, pp.305-308. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022007000200010.

The nutrient foramina of the femur and fibula are located in the middle third of the diaphysis of these bones, on the other hand in the tibia it's in the proximal third of its diaphysis. With the objective of complementing the information delivered by other authors, we investigated the location, the number of diaphysis foramines, the distance or position of the foramines in relation to the length of the bone and the proximal epiphysis and the diameter of the bone at the height of the foramen. For that purpose, we used 140 dry bones (50 femora, 50 tibiae and 40 fibulae) of adult subjects of both sexes from the Anatomy Museum Faculty of Medicine, Universidad de La Frontera, Temuco, Chile. The nutrient foramen of the femur was located in the linea áspera in the 72,5% (36,25% in the interstice, 8,75 in the lateral lip of the linea áspera and 27,5 in the medial lip of the linea áspera), and in the 21,25% in the medial surface and in the 6,25% in the lateral surface of the diaphysis of the bone. The nutrient foramen of the tibia was found under the soleal line in a 94,33% at an average distance of 117.8mm from the intercondylar eminence to the nutrient foramen (in the superior third of the bone), in the soleal line of the bone in 3,77% and in the lateral border in 1,88%. In the fibula the nutrient foramen was found in the 68% in the posterior surface; 14% in the medial surface; 12% in the interosseous border; 4% in the lateral surface and 2% in the posterior border. This data could be useful as reference for surgical procedures of the lower limb
