Does femoral antetorsion differ between asymptomatic volunteers and patients with different types of femoroacetabular impingement?
MR imaging can reproducibly measure femoral antetorsion, which is significantly larger in pincer-type compared to cam-type FAI.
Femoral antetorsion can be measured rapidly and with good reproducibility with MR imaging. Patients with pincer-type FAI had a significantly larger femoral antetorsion than patients with cam-type FAI.
