Case Discussion
the presence of a fat pad sign, mostly means there is an intra-articular fracture
the most common cause of elbow joint effusion in adults is a radial head fracture
sometimes the intra-articular fracture may not be visible, at that time it is called an occult fracture, and needs further imaging with either MRI, CT, or nuclear medicine studies to make the diagnosis
