How to Avoid Missing a Pediatric Elbow Fracture - ACEP Now

Those of us who manage kids with acute elbow injuries undoubtedly see pulled elbows and supracondylar fractures. We look for effusions on lateral X-rays, think about the anterior humeral line, and possibly recall the mnemonic CRITOE (see below). Supracondylar fractures comprise 60 to 70 percent of pediatric elbow fractures; the bulk of the rest are two commonly missed fractures.
