Little League elbow, technically termed medial epicondyle apophysitis, is a condition that is caused by repetitive overhand throwing motions in children.

[4] In 2007, in order to protect against overuse injuries, Little League Baseball began limiting the number of pitches a player could throw per day.

Instead, adult athletes have a fused growth plate, meaning that ligaments and tendons must bear the stress of the repeated throwing motion.

[9] Doctors usually notice Little League elbow based on physical exam and history, as X-rays are typically normal.

[3] X-rays may be helpful to check if the growth plate is open, see if loose bone chips are present, and see if there are signs of early arthritis.

[10] Following a pitching outing, athletes should rest their arms for a day or two, and should avoid other high-demand throwing positions on the field (eg.

Another key of prevention is proper throwing form and avoidance of "offspeed pitches" to minimize stress on the elbow.

Rehab consists of focused physical therapy to increase elbow range of motion and build muscle groups for throwing (arm, shoulder, back, and core).
