Little league elbow and shoulder

Little league elbow and shoulder are overuse injuries that affect young throwing athletes, causing pain, weakness or reduced motion in the elbow or shoulder joint. These conditions develop gradually from repetitive throwing motions common in baseball and softball. With early diagnosis and the right care, most young athletes recover fully and return safely to the sports they love.

Anatomy of the elbow and shoulder

The elbow and shoulder work together to power each throw. In young athletes, growth plates, areas of soft cartilage near the ends of bones, are still developing. The elbow's growth plate sits on the inside of the joint; the shoulder's is near the top of the upper arm bone.

Because growth plates are softer than mature bone, they're more vulnerable to repeated throwing stress. Little League elbow affects the growth plate on the inside of the elbow; Little League shoulder affects the growth plate near the shoulder.

Overview

Symptoms

Little League elbow and shoulder often develop slowly, and young athletes may not mention pain until it starts affecting their performance. Watch for:

Pain in the elbow or shoulder during or after throwing
Reduced throwing speed or accuracy
Swelling around the elbow or shoulder joint
Tenderness to the touch
Limited range of motion
Elbow that feels like it locks or catches
A noticeable decrease in pitching or throwing distance

Symptoms typically start mild and worsen with continued throwing. Pain that once appeared only during activity can eventually persist at rest if not addressed.

Causes

Little League elbow and shoulder result from repetitive stress on growth plates that haven't fully matured. Common contributing factors include:

Throwing too many pitches without adequate rest
Poor throwing mechanics
Playing on multiple teams or in multiple leagues at once
Pitching curveballs or other breaking pitches at a young age
Insufficient rest between seasons

These injuries build up over time rather than occurring from a single incident.

Risk factors

Certain factors can increase a young athlete's chances of developing Little League elbow or shoulder, though having one or more of these does not mean an injury is guaranteed:

Pitching or throwing year-round without an off-season
Playing catcher or pitcher, positions with high throwing volume
Early specialization in baseball or softball
Fatigue during play
Inadequate warm-up before throwing activities

Understanding these risk factors can help families and coaches make informed decisions about training and playing time.

Diagnosis

Diagnosing Little League elbow or shoulder starts with a discussion about throwing history, position played and how symptoms developed. A physical exam checks for tenderness, swelling and range of motion in the affected joint. Imaging tests, such as X-rays, may be used to evaluate the growth plate and rule out other injuries.
