The Lacertus Syndrome of the Elbow in Throwing Athletes.

When more obvious and common causes of elbow pathology are ruled out, it is important to be aware of uncommon causes of elbow pain in throwers. The Lacertus syndrome can be a debilitating problem when overlooked; however, it can be easily diagnosed with a careful history and physical examination. If the description suggests a postexertional compartment-like problem, consider having the patient throw before the examination, and the diagnosis becomes easier to either confirm or rule out. Once the diagnosis is established treatment includes rest or fasciotomy. Recovery is uncomplicated and athletes can return to throwing within a month.
