Little League elbow is a stress injury of the medial elbow growth plate in skeletally immature throwing athletes. The condition is the elbow equivalent of Little League shoulder and develops from repetitive valgus loading during the throwing motion. Recognition matters because continued throwing can worsen the injury and lead to permanent growth plate damage.
What Is Little League Elbow?
The medial epicondyle is the attachment site for the wrist flexor muscles and the ulnar collateral ligament. In skeletally immature throwers, the medial epicondyle has its own growth plate (apophysis) that is the weakest link in the medial elbow. Repetitive valgus loading during the throwing motion stresses this growth plate, producing inflammation, widening, and pain. In severe cases, the medial epicondyle can avulse off the humerus.
The condition is typically seen in baseball pitchers ages 9 to 14 and is closely related to pitch counts, throwing volume, and pitch type.
Causes and Risk Factors
- High pitch counts in young pitchers (the most consistent risk factor)
- Year-round throwing without adequate rest periods
- Throwing breaking pitches at young ages
- Pitching for multiple teams concurrently
- Poor throwing mechanics
- Skeletal immaturity with open medial epicondyle apophysis
- Age 9 to 14 is the most common demographic
Symptoms
- Medial elbow pain with throwing
- Decreased pitch velocity or command
- Loss of pitch effectiveness
- Pain that resolves with rest and recurs with throwing
- Tenderness over the medial epicondyle on examination
- Pain with valgus stress testing in advanced cases
- Visible deformity if avulsion has occurred
Diagnosis
Dr. Chudik’s evaluation includes the pitch count history, throwing pattern, and a focused examination. Tenderness over the medial epicondyle and pain with valgus stress reproduce the symptoms. X-rays compare the affected side to the opposite elbow, looking for widening or avulsion of the medial epicondyle. MRI characterizes the inflammation pattern and detects subtle apophyseal injury. The Westmont office has on-site high-field MRI and X-ray.
Treatment
Treatment is almost always non-surgical for non-displaced injuries. The cornerstone is rest from throwing for six to 12 weeks. During this period:
- No throwing of any kind, including warm-up tosses
- A targeted physical therapy program for elbow mechanics, scapular control, and core strengthening
- Mechanical review with a coach or pitching specialist
- Progressive non-throwing conditioning
Once symptoms resolve and imaging shows recovery, a graduated return-to-throw program is started.
Surgical treatment is reserved for displaced medial epicondyle avulsions, which are uncommon. Dr. Chudik performs open reduction and internal fixation when needed.
Recovery and Outcomes
Recovery typically takes three to four months from the start of rest to full return to competitive throwing. Outcomes are excellent when the condition is recognized early and the rest period is respected. Continued throwing through pain extends total time away from sport and risks more severe injury.
Preventing recurrence requires adherence to age-appropriate pitch counts, adequate rest days, and attention to throwing mechanics.
When to See Dr. Chudik
Schedule an evaluation if a young thrower has medial elbow pain that has persisted beyond a throwing outing or two, or if velocity or command has dropped without clear injury. Call 630-324-0402 or request an appointment online.
