Patient Data

Age: 31
Gender: Male

CT Pelvic bones

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 a syndrome of painfully limited hip motion as result of certain types of underlying morphological abnormalities in the femoral head - neck region and / or surrounding acetabulum. On this case there is a osseous bump causing a CAM type impingement. 

This can lead to early degenerative disease.
