Baseball Injuries

Injuries in young athletes are on the rise, but elbow and shoulder injuries in children are on the verge of becoming an epidemic. Thousands of children are seen each year complaining of elbow or shoulder pain. Damage or tear to the ulnar collateral ligament (UCL) is the most common injury suffered and is often caused by pitchers throwing too much. This ligament is the main stabilizer of the elbow for the motions of pitching. When it becomes damaged, it can be difficult to repair and rehabilitate.

How Is an Elbow or Shoulder Injury Diagnosed?

Warning Signs

If a young athlete is throwing too hard, too much, too early, and without rest, a serious elbow or shoulder injury may be on the horizon. If the athlete complains of elbow or shoulder pain the day after throwing, or movement of the joint is painful or restricted compared to the opposite side, see a physician familiar with youth sports injuries immediately.

When to Act

Do not wait for pain to go away on its own. Early diagnosis is critical to preventing long-term damage. A physician familiar with youth sports injuries should be consulted as soon as any of the warning signs appear. Prompt evaluation can prevent a minor issue from becoming a season-ending — or career-ending — injury.

How Can Overuse Baseball Injuries Be Prevented?

Overuse injuries — especially those related to the UCL and shoulder — are preventable. Some tips to keep you in the game throughout your life include:

How Is an Overuse Elbow or Shoulder Injury Treated?

The most obvious treatment for overuse is rest, especially from the activity that created the injury. Ice is also used to reduce soreness and inflammation. Ibuprofen can be taken to help with any pain. If symptoms persist, it is critical that a physician be contacted, especially if there is a lack of full-joint motion. An examination and radiographs should be done. An MRI scan may also be helpful.

Usually a simple “rest cure” approach will not be enough, because even though it allows symptoms to subside, it also creates loss of muscle bulk, tone, flexibility, and endurance. Once pain is gone and full motion is present, a throwing rehabilitation program can start.

Under some circumstances, surgery may be necessary to correct a problem. Overuse and stress related problems can affect growing parts of bone, not just the soft tissue
(muscles, tendons, and ligaments). If the condition is not treated, it could cause deformity of the limb and permanent disability. The athlete should return to play only when clearance is granted by a health care professional.
