A study of Diaphyseal Nutrient Foramina in human lower limb long bones and its clinical importance
Journal Title: INTERNATIONAL JOURNAL OF CURRENT RESEARCH IN MEDICAL SCIENCES - Year 2016, Vol 2, Issue 7
Abstract
The diaphyseal nutrient artery, main source of blood to a long bones. A natural opening in the shaft of the long bones, Nutrient foramen allows these arteries into the medullary cavity. The objective of this study is to investigate the location, number and direction of the nutrient foramen in long bones of adult lower limbs. The study was conducted on 150 human lower limb long bones. Non-metrical and metrical measurements were investigated Femora had foramen on the middle one-third between 25% and 63%, on the linea aspera. Majority of them had single dominant foramen of large size caliber directed towards the proximal end. However, in Tibia, upper one-third (between 27% and 44%) was the most common location of nutrient foramen. Most of the nutrient foramen were large in diameter and were directed towards the distal end of the bone. In fibula, the most common position of the nutrient foramen was between 31% and 75%, that is, middle one-third. Majority of the dominant foramina were of medium size caliber.However, in 6 fibulae the nutrient foramina were directed proximally which violated the law. An accurate knowledge of the location of the nutrient foramina in long bones can be useful in certain surgical procedures like bone grafting, microsurgical vascularized bone transplantation and in many fractures.
