Computed tomography in the measurement of femoral anteversion.

A new technique using computed tomography for measuring femoral anteversion is presented, with advantages over prior techniques. Computed tomography allows the visual portrayal of the cervical axis to be superimposed upon the diacondylar axis for direct goniometric measurement of the anteversion angle. Beyond its accuracy, the procedure requires no complicated positioning framework and can be done in a brief span of time.
