Repetitive microtrauma is one of the major underlying etiologies for the development of OCD in the capitellum seen in high-level athletes, especially pitchers and gymnasts.
The differential diagnosis list for LE also includes synovial plica, cervical radiculopathy, osteochondritis dissecans of the capitellum, and radiocapitellar arthrosis, (3,4,6) several of which require special imaging in order to rule out.

The capitellum should be in front of this humeral line, and it should be about 30 degrees of tilt forward.
The diagnosis of osteochondritis dissecans (OCD) of the capitellum was established.
Existing radiographs (Figure 1), although taken under suboptimal conditions, revealed no malalignment of the radiocapitellar line, a line drawn along the long axis of the radial neck, which should bisect the capitellum on all projections [1].
