Elbow joint- Watch out for the fat pads!!
1 )35 yrs male with history of trauma
Sail sign- Anterior displacement of anterior coronoid fossa fat pad due to joint effusion.
Posterior fat pad is displaced out from the olecranon fossa.
These features favour joint effusion. In adults the commonest site of intra-articular fracture producing these signs is the radial head. The subtle radial head fracture is also seen in above images.
In children its the supra-condylar fracture which produces these signs.
2) Radius neck fracture with fat pad sign-
