The study analyzes the position of primary nutrient foramina of tibia and fibula.
137 adult dry bones including 71 tibias and 66 fibulas were studied. The number and position of primary nutrient foramina was noted and the foraminal index was calculated.
A single primary nutrient foramen was observed in all the tibia and fibula. 97.18% of tibia had foramen on the posterior surface and 2.82% on medial surface. In the fibula all the foramina were on the posterior surface. The mean foraminal index was 32.08 in tibia and 44.60 in fibula. In the tibias 74.65% of the foramina were in the upper third and in the fibula 95.45% of the foramina were in the middle third.
A knowledge of foraminal topography helps to preserve bone vasculature during surgeries. This increases the success of fracture fixation, bone grafting and knee replacement procedures involving the bones.
