Abstract :

introduction– Bones are structures that adapt to their mechanical environment and from the fetal age adapt to the presence of naturally occurring holes. These holes are called as nutrient.Method–The study was conducted on 100 fibulae, using osteometric board, vernier caliper, and hand lens. Adult fibulae were examined for position of nutrient foramen from the styloid process by calculating forminal index using Hughs formula and its variation. Result– most common distribution of nutrient foramina was on middle one third of the bone (Type–2), seen in 86.59% of fibulae, followed by 7.2% in lower one third (Type–3), and then 6.18% on upper one third of bone (Type–1)with mean ForminalIndex(FI) 43.04±9.35,mean length of fibulae is 35.87 (SD±2.35), distance of nutrient foramina (DNF) is 15.41 (SD±3.63).Conclusion–. Most common location of nutrient foramen was in the middle 1/3^rd of posterior surface of fibula. Thus middle 1/3^rd of fibula must be used for transplant to reconstruct mandible, stabilization of spine and tibia, as well as for dental implants, and also in avascular necrosis of femoral head.
