Title: Panner's disease<br/>Author: Brian Corwell<br/><a href='http://umem.org/profiles/faculty/294/'>[Click to email author]</a><hr/><p>
9-year-old male left hand dominant, presents with left elbow pain.</p>
<p>
He is a future “star pitcher,” says his coach dad. “Doc, I bet you didn’t know that although only 10% of people throw with their left hand almost a 1/3<sup>rd</sup> of MLB pitchers are lefties. He is 3x more likely than a righty to pitch in MLB.” “Maybe I’m asking him to throw too much.”</p>
<p>
<strong>Hx</strong>: Lateral elbow pain and “stiffness” worse with activity that is better with rest</p>
<p>
<strong>PE</strong>: Lateral elbow tenderness (capitellum) with slight (approx. 20 degrees) decreased loss of extension. Minimal swelling noted.</p>
<p>
<strong>Dx</strong>: Panner's disease refers to osteochondrosis of the capitellum (similar to Legg Calve Perthes). Likely due to AVN from repetitive trauma. May also be due to endocrine disturbances.</p>
<p>
Affects the dominant elbow of boys between the ages of 5 and 10</p>
<p>
Associated with the repetitive trauma of throwing or gymnastics.</p>
<p>
Must be differentiated from osteochondrosis dissecans which occurs in the older child >13yo when the ossification of the capitellum is complete</p>
<p>
<strong>Radiology</strong>: </p>
<p>
The articular surface of the capitellum may appear irregular or flattened with areas of radiolucency (43%). Loose bodies not seen with Panners, much more likely with OCD lesions.</p>
<p>
<strong>Treatment</strong>: Ice and NSAIDs. Avoid pitching/gymnastics etc. until full radiographic and clinical healing. If significant pain and/or swelling place patient in long arm posterior splint for 7-10 days. Resolution may take several months and up to one year.</p>
