%X Background: The femoral neck anteversion has important implications. Since these values are not documented for our population, we undertook this study to define this for Indian population. Methods: FNA was calculated on 300 dry femora by the Kingsley Olmsted method, and prospectively on otherwise normal living adults by CT method (n=72 hips), by biplanar radiography (n=138 hips) and clinically (n=138 hips). Results: The mean FNA by CT was 7.4กใ (SD 4.6กใ) and more than 75% of cases were between 3.4กใ and 11.4กใ. The mean FNA by X-ray method was 11.5กใ (SD 5.4กใ) and more than 71% of cases were between 6.5กใ and 16.5กใ. The mean, clinically, was 13.1กใ (SD 4.6กใ) and almost 75% of cases were between 9.1กใ to 17.1กใ. The mean FNA on dry femora has been calculated as 8.1กใ (SD 6.6กใ) and almost 62% of cases were between 3.1กใ to 13.1กใ. The mean FNA on right side was statistically significantly 1.7กใ less than on the left side. Statistically significant difference between the sexes was found only by the dry bone method (F>M = 3กใ). Conclusions: Considering CT to be most accurate on living subjects, FNA in our study has been found to be 7.4กใ (SD 4.6กใ). It is 4 -12กใ lower than most of the western studies by all these methods. Readings are 4.1กใ higher by the X-ray method and 5.7กใ by the clinical method. Correlation and regression equations have also been formed between the various methods and the clinical method correlates better than the X-ray method to the CT method.
