Coronal and axial oblique images exhibit typical piston-grip deformity of bilateral proximal femora, lack of femoral neck concavity, diminished femoral head-neck offset, aspherical femoral heads, acetabulo-femoral uncovering and bony bump with subchondral edema at anterosuperior neck . The lateral femoral tubercles are also prominent. These features are compatible with bilateral CAM type of femoroacetabular impingement ( FAI type 1 ).
The right hip reveals linear knife like hyper intensity at anterior labrum along the articular surface reaching midsubstance of labrum, suggesting partial anterior labral tear.
The left hip reveals a large anterosuperior complete labral tear with intervening fluid cleft ( 10 - 2 o'clock position). A chronic femoral neck fracture is seen with marrow edema and cortical overriding with minimal edema at iliopsoas muscle and small volume joint effusion.
