FCP or UAP?

A

FCP

  • Fractured coronoid process*
  • Note the new bone formation on proximal aspect of anconeal process. THIS IS NOT UNUNITED ANCONEAL PROCESS*
29

Note the increased opacity of the medullary cavity

30
Q

A

True

31
Q

A
36
Q

What disease are we observing in this image?

A

Legg-Calve-Perthes

  • Aseptic necrosis of the femoral head*
  • Note the widening of the joint space due to hyperplastic cartilage as well as the deformation of the femoral head*
