Abstract

Background: The purpose of this study to estimate mean values of femoral anteversion, acetabular anteversion, combined anteversion and anteversion ratio in normal Indian population.


Methods: It is a prospective study conducted between october 2019 to May 2023 in R.D.Gardi Medical College, Ujjain, M.P.188 normal Indian adults (376 hips), of which 96 were males and 92 were females, fulfilling the inclusion and exclusion criteria selected on a random basis were included in the study.


Results: The mean FA in our study was found to be 16.020, with a mean value of 16.560 on the right side and a mean value of 15.490 on the left side. The mean AA in our study was found to be 16.110, with a mean value of 17.050 on the right side and a mean value of 15.180 on the left side. The mean CA in our study was found to be 32.140, with a mean value of 33.610 on the right side and a mean value of 30.670 on the left side.  Mean anteversion ratio in the total population was found to be 1.11, with a mean of 1.07 on the right side while on the left side it was 1.16.


Conclusion: The correct estimation of FA, AA, CA and AR in a given population depends on the appropriate method along with a proper technique. MRI was found to be better and safer than CT scan, as oblique images of the femoral neck can be obtained without the use of ionizing radiation.
