Location and Clinical Significance of Nutrient Foramina of Human Long Bones of Lower Limb
Abstract: Introduction: The nutrient artery is the chief source of blood of a long bone particularly during its active growth period. Nutrient canal normally slanted during growth. The direction of slant from outer surface to marrow cavity points towards the end that has grown relatively slowly. This is due to greater longitudinal growth at the rapid growing end. Material and methods: The material of present study consisted of 150 (50 femur + 50 tibia + 50 fibula) adult human long bones of lower limb. The location of nutrient foramina is determined by using foraminal index formula and number of foramina were examined of all the bones. Foraminal index = (DNF/TL) x 100. DNF- distance from the proximal end of the bone to the nutrient foramina, TL ? total bone length. Results: 150 adult human dried bones were taken for the study. Among 64 nutrient foramina of femur 90.62% were on the medial lip of linea aspera (Expected site) and 9.38% on lateral lip and anterior surface (Variant site). In 53 nutrient foramina of tibia 100% were located on posterior surface (Expected site). In 52 nutrient foramina of fibula 100% were located on posterior surface (Expected site). Conclusion: The knowledge about nutrient foramina of long bones of lower limb is useful in certain surgical procedure to preserve the circulation.
