Radiocapitellar Impingement after a Pediatric Type II Capitellar Fracture.

We present a case of radiocapitellar impingement caused by osteochondral fragment after type II capitellar fracture. Painful extension limitation of the elbow was treated successfully by diagnostic arthroscopy and mini-open removal of loose body. A displaced type II capitellar fracture in children is extremely rare, but must be carefully diagnosed and treated.
