Morphometric Study Of Nutrient Foramen In Diaphysis Of Lower Limb Long Bones With Their Clinical Significance.

[摘要] Knowing the number, location and direction of nutrient foramen which will immensely helporthopedic surgeons, to carry out hassle free surgeries without affecting nutrient artery and help in fastand rapid wound healing. To study the number, location and direction of nutrient foramen in the lowerlimb long bones. The study was carried on 150 human adult, dry lower limb long bones (50 femur, 50tibia and 50 fibula) for a period of 6 months in The Oxford Medical College, Hospital and Research Centre,Bangalore. Number of nutrient foramen in each bone are checked, it’s location on the surface of shaft ofeach bone is observed, distance of each foramen from upper end, length of each bone is measured byosteometric board and foraminal index is calculated. Out of 150 lower limb long bones, 81.33% of thelong bones had single nutrient foramen. Foramina on these bones were found on the posterior surface ofrd rd the shaft of bone. Foramina were located either in upper 1/3 or in the middle 1/3 of the shaft of eachbone and are directed away from growing end, with an exception of fibula where 12%of the foraminawere directed upward which is it’s growing end. This study provides information regarding normal andvariant number, location and direction of nutrient foramen of each lower limb long bones which helpssurgeons to plan orthopedic surgeries accordingly.
