Objective To determine the average angle of Femoral Neck Anteversion (FNA) in bones of South Indian population. Methods: One hundred and fifty intact dry femur bones belonging to 78 males (63 Right & 15 Left) and 72 females (36 Right and 36 Left) were chosen for the study. The FNA, angle between a transverse line that passes through bicondylar plane of the distal end of femur and an imaginary line passing through the center of femoral head and neck were evaluated by Kingsley Olmsted method and the results statistically analyzed. Results: The mean FNA of the bones observed was 12.86 0 + 7.38 0 . The mean measurements in the male and female bones was 14.11 0 + 6.19 0 and 11.5 0 + 8.32 0 . It was observed that in 58% of bones the FNA was 11‐20 0 , in 24% it was 0‐ 10 0 , in 12% it was 21‐ 30 0 and in 9% bones the femoral neck was retroverted. Conclusion The cause for variation in measurement of FNA can be multifactorial and has important implications in arthroplasties and evaluation of pathology of hip. The values of the present study add to the data on FNA as it is known to increase in conditions like Perthe's disease, cerebral palsy, postural defects etc and is known to decrease in toing out and rickety chondrodystrophy.
