Little Leaguer's shoulder is an injury to the upper arm bone at the shoulder. It happens to young athletes who are still growing.
This problem is also called proximal humeral epiphysitis.
Little Leaguer's shoulder is caused by overuse of the arm, usually from too much pitching or throwing. The bones of young children are still growing. Repeated throwing causes wear and tear on the new, weaker bone in the shoulder.
Little Leaguer's shoulder happens most often in young baseball pitchers between the ages of 11 and 16. Children playing other baseball positions and other sports, like tennis, are also at risk for this injury.
Children who play baseball year-round are more likely to have overuse injuries.
The main symptom is pain in the upper arm at the shoulder during throwing. Children may keep having pain and tenderness after their activity is over. The shoulder muscle may be weak. Some children may not be able to throw as fast or as accurately as they used to.
Your child’s healthcare provider will ask about your child’s symptoms, medical history, and activities and examine your child's shoulder. Tests may include X-rays or other scans.
The most important treatment is resting of the arm and shoulder. Depending on how severe the injury is, your child may need to stop throwing for 1 to 3 months. During this time your healthcare provider may recommend stretching and strengthening exercises and other types of physical therapy to help your child heal.
The pain often gets better within a few weeks with self-care, but some injuries may take several months or longer to heal. It’s important to follow all of your healthcare provider’s instructions.

When your child is not pitching, he or she needs to be sure they are not throwing hard while playing your child to learn proper pitching technique.
Children should not play through pain. If your child’s arm hurts, your child should stop throwing.
