Introduction: Introduction: The position of nutrient foramen on the shaft of long bones is specific. It transmits nerve and vessels which help in maintaining nutrition of bone. Blood supply by nutrient artery is essential during early phases of ossification as well as during growing period which passes through the nutrient foramen.
Aim: To study the topography and location of nutrient foramen on the shaft of the tibia.
Materials and Methods: For the present study, 70 adult dry tibia of unknown age and sex were studied. The number, direction and location of nutrient foramen were noted. Using Hughes formula, foraminal index was calculated.
Results: A single nutrient foramen was present in all tibia. In all the bones they were directed downwards except in two bones where it was directed upwards. Nutrient foramen was situated on posterior surface except in two bones where it was on lateral surface of one bone and lateral border of other bone. Average total length of tibia was 35.11 cm while average distance of nutrient foramen from proximal end was 11.79 cm. In 45 tibia, foraminal index was <33.33 which indicates that in 64.28% of tibia foramen was on upper 1/3 of shaft.
Conclusion: The precise knowledge and topography of nutrient foramen of tibia will help surgeons and orthopaedicians in minimising damage to vasculature of tibia during various surgical procedures.
