Introduction: Introduction: Nutrient foramina are important as they provide passages to the nutrient arteries into the marrow cavity of long bones, which are the principal source of blood supply and nourishment of long bones. Active bone growth in embryo, fetus and early phase of ossification depend on its blood supply.
Aim: To note the number, position, direction and obliquity of nutrient foramen along with measurement of physiological length, foraminal index and co-relations between foraminal index and distances of nutrient foramina from three important bony landmarks. The present study also included comparison of above data between right and left sided femur.
Materials and Methods: The present study was conducted on 60 adult, dry, cleaned normal human femur (30 right and 30 left), collected from the Department of Anatomy, ESIC & PGIMSR Medical College, Joka, Kolkata for a period of three months from September to November, 2016. The objectives of the study were noted and analysed.
Results: The study revealed predominance of single foramen in 63.66% femur. There was no nutrient foramen in two right sided femor. The nutrient foramina were predominant on middle 1/3rd of femoral diaphysis (94.94%), both on right and left sides mostly on and around linea aspera. All foramina were directed proximally and there was no change in obliquity. The foraminal index ranged between 36.741±2.122 to 58.008±2.218. The study also showed positive co-relations between foraminal index and distance of nutrient foramina from fovea, lesser trochanter, mid intertrochanteric crest separately each being statistically significant.
Conclusion: The present study is useful in calculating the length of a long bone from a given fragment which is important for medicolegal and anthropological work. It is also important for vascular bone grafting.
