Background: As the environment plays an important role in the development, the regional variation of the femur bone is influenced by geographical area, sex, stature, and heredity. In the present study, measurements on the adult human dry femora have been carried out. The knowledge of variations in the parameters of dry femora will help the orthopedicians and also assist prosthetists to design a suitable prosthesis for restoration of normal neck-shaft angle (NSA) and will also help forensic anthropologists to determine the sex. Objectives: The objectives of this present study is to determine the various parameters including femoral length, anterior neck length, and NSA of femur among Indian population and to compare them with the data available in the literature. Materials and Methods: This study was done on 100 adult dry human femora of unknown age and sex (50 right side and 50 left side), collected from the Department of Anatomy and students of J. N. Medical College, Belagavi, Karnataka, India. Results: In the present study, the length of femur ranged from 336 to 485 mm with the mean of 413.15 mm. Length of right femur ranged from 346 to 472 mm with the mean of 409.4 mm and that of left femur ranged from 336 to 485 mm with the mean of 416.9 mm. The anterior neck length of femur ranged from 20 to 40 mm with the mean of 28.8 mm. The anterior neck length of right femur ranged from 20 to 38 mm with a mean of 28.8 mm and that of left femur ranged from 21 to 40 mm with the mean of 28.8 mm. The NSA ranged from 115° to 140° with the mean of 127.21°. In the right femur, it ranged from 115° to 137° with the mean of 126.78°, and in the left femur, it ranged from 119° to 140° with the mean of 127.64°. Conclusions: There was no comparative difference between the values of right and left sides for all parameters. The values observed for all three parameters were greater in the Western world than in the present study, and it was concluded that Western people were taller and heavier than the average Indians, thus showing the regional variation. Clinically, this study plays an important role for orthopedicians and prosthetists to build suitable prostheses for Indians.
