Résumé
Aim: The aim of the study is to determine the variations in diaphyseal nutrient foramen(NF) of femur with respect to theirnumber, location, direction and size in Jharkhand state population.Materials and Methods: 70 dry adult femora(38 Right side and 32 Left side) were collected from the department of Anatomy,Mahatma Gandhi Memorial Medical College, Jamshedpur, Jharkhand. Femora were examined for mean length of femur, number,position including foraminal index, direction and size of nutrient foramina.Result:- Mean length of femur was 42.27cm. According to Foraminal Index the location of nutrient foramina were 72.34% inright side and 86.84% were located in left side in middle 1/3 of bone. Most common position was between two lips of Lineaaspera(42.35%). Single nutrient foramen was 64.70%.Conclusion:- The knowledge of anatomical variation in diaphyseal nutrient foramen of femur is important for bone ossification,bonehealing and it also give additional information to orthopedicians for microvascular bone grafting.
