B.... most senesitive.

The correct answer is B. The posterior fat pad sign,
which indicates an effusion in the joint, is the most
specific of the findings for a radial head fracture. An
anterior fat pad sign is the most sensitive.
There is no medial fat pad sign, and while there
might be a Trusseau™s sign somewhere, it is not at all
related to the radial head.
