STUDY OF VARIATIONS OF NUTRIENT FORAMINA IN LOWER LIMB LONG BONES

Author(s): Arun Kumar S. Bilodi1

BACKGROUND
The objective of the present study is to know the variations of the numbers, the directions, the locations and the shapes of the nutrient foramina that is observed in the long bones of lower limbs i.e., Femur, Tibia and Fibula. Place of Study: This study was done in the Department of Anatomy at Sree Mookambika Institute of Medical Science, Kulasekharam in Kanyakumari district of Tamil Nadu. Period of Study: This study was done during the month of July and August of 2015.
MATERIALS AND METHODS
The bones of lower limb from the Department of Anatomy of the above institute constituted the materials for the present study. A thorough study was done on Nutrient Foramina of the long bones of Lower limb i.e., femur, tibia, fibula. Each bone was carefully observed for the variations of nutrient foramina, about their numbers, shapes and directions. All the findings were observed and then noted in the tabular form and later they were well compared and correlated with available literatures.
RESULTS
Present study was done on 29 femora on the right side and 30 on the left side. The study showed, double foramina in only one bone on the right side but not on left side and no bone showed more than two foramina. The highest percentage of single foramen was seen on femur of left side [69.69 %] followed by 59% on the right side. Double foramina were more seen on the right side [28.12%] and the absence of foramina were 12.5% on the right side and 3.03% on the left side. Our study showed double foramina in only one bone on the right side, but not on left side and no bone showed more than two foramina.
CONCLUSION
This study provides an additional information regarding the morphology and topographical study. The knowledge of nutrient foramina is the paramount importance in some of the surgeries in order to preserve the circulation of the bone. Hence, it has been studied in detail and reported.
