Panner's Disease

What is it?
The radius and capitellum are the two bones on the outer side of the elbow. Very young patients, ages 6-10, can have flattening and fragmentation of the normally round (hemispherical) capitellum part of the distal humerus. It is not certain that this is only seen in throwers, but it does cause more problems with throwers than for non-throwers.

What does it feel like?
It is usually a dull ache that is worse with throwing. Decreased endurance and poor pitch speed and location are common.

How is it treated?
Nonoperative treatment is usually successful . Casting or bracing for a short time followed by a long time off is required.

Operative treatment is rarely required. If bone chips develop which cause popping, clicking or locking of the elbow joint, arthroscopic surgery could be recommended.

How long will I be out of throwing?
If nonoperative treatment is successful, about 6 months.
If surgery is required, about 6-12 months.
