What is Thrower’s Shoulder?

A throwing athlete is an athlete that repetitively uses the “throwing” motion throughout their games, workouts or trainings. Baseball players, swimmers, basketball players and more are all affected by thrower’s shoulder. Thrower’s shoulder, also known as “little league shoulder” is an overuse injury to the upper arms (humerus) growth plates caused by the repetitive throwing motion. The term “little league” is coined because athletes between the ages of 8 to 12 are most susceptible to this injury. Below, we will go over everything you need to know about this injury.

How is Thrower’s Shoulder Injury Sustained?

A thrower’s shoulder injury is sustained through repetitive “throwing” motions that stress the humerus near the shoulder and widen the growth plate. This results in swelling and pain in the shoulder, most common in players aged 8-12. The most common contributors to thrower’s shoulder are pitching and throwing without the proper technique and mechanics, overusing the shoulder and not resting between pitching, and lack of upper back and shoulder strength to support proper throwing.

Symptoms of Thrower’s Shoulder

There are some common symptoms of little league shoulder to be on the lookout for. Pain and weakness in the shoulder when completing the throwing motion are the most common symptoms. For any young athlete, pain and or weakness when performing a repetitive motion should always be addressed with a medical professional immediately. Your child may not want to admit they are in pain, but thrower’s shoulder will cause the athlete to change the way they are throwing to avoid the pain. Th
