There is a decreased offset of the femoral head-neck junction, which is the difference between the widest diameter of the femoral head and the most prominent part of the femoral neck, that appear as a lack of the normal wasting of the femoral head-neck junction. There is also a prominent lateral extension of the femoral head at the expected step-off to the adjacent femoral neck (femoral “bump”).
Case Discussion
Femoro-acetabular impingement is an impingement syndrome of painfully limited hip motion as a result of certain types of underlying morphological abnormalities in the femoral head-neck region and/or surrounding acetabulum. In this case, the osseous bump or cam morphology is causing the impingement.
This can lead to early hip osteoarthritis.
