Femoral retroversion

Discussion:

Femoroacetabular impingement (FAI) and femoral retroversion

In this patient, both the cam-type deformity and the femoral retroversion contribute to a decreased internal rotation of the hip joint. Cam-type femoroacetabular impingement is associated with decreased femoral anteversion (or even femoral retroversion, as in this case). Because there is a wide range of femoral anteversion values both in the healthy population and in patients with femoroacetabular impingement, it is recommended that femoral anteversion is assessed individually in all patients with suspected femoroacetabular impingement.
