A study of the nutrient foramina in human long bones.

The present study analyzed the location and number of the diaphysial nutrient foramina in six long bones of adult human skeletons of unknown age and sex from a statistical view point. The diaphysial nutrient foramina in the humerus, are located at between 50 and 65% of the total length; in the radius and ulna, at between 25 and 50%; in the femur, at between 25 and 58%; in the tibia, at between 30 and 40%; and in the fibula at between 35 and 67%, i.e. the middle third of the bone. Also studied were the anatomical position and number of the diaphysial nutrient foramina in each bone.
