Is there a relationship between femoral anteversion and leg torsion?

In this study, the association between increased femoral anteversion and external torsion of the leg was investigated by computed tomography in adults. In a control group of 15 women, the anteversion angle of the femoral neck measured 11 degrees +/- 9 degrees and 12 degrees +/- 9 degrees for the right and left sides, respectively. The external torsion of the leg was 40 degrees +/- 8 degrees and 39 degrees +/- 10 degrees, respectively. The patient group consisted of 16 women who were evaluated for clinical symptoms related to increased femoral anteversion. In this group, the femoral anteversion was 31 degrees +/- 7 degrees and 33 degrees +/- 7 degrees for the right and left sides, respectively, and the external torsion of the leg was 35 degrees +/- 10 degrees and 33 degrees +/- 12 degrees, respectively. There were no correlations between the degree of femoral anteversion and the degree of external torsion of the leg. This study indicates that in cases of increased femoral anteversion, compensatory external torsion of the leg does not develop regularly during growth.
