What it is
Little League Elbow is irritation of the growth plate and tendon attachment on the inner elbow in children and adolescents. Valgus stress during throwing loads the medial apophysis before it has matured. Pain rises with repeated throwing and settles with rest and a planned return.
The goal is to calm the growth plate, build forearm and shoulder capacity, and then reintroduce throwing with sound mechanics and season planning.
What happens when it occurs
Rapid arm rotation and late cocking create traction at the medial apophysis. The flexor–pronator muscles attempt to protect the elbow, but fatigue redistributes the load to the growth plate. A rest phase is followed by strength and control work, then an interval return‑to‑throw plan.
Common causes and risk factors
- High throwing volumes, overlapping school and club seasons
- Fast bowling or pitching without a gradual build-up
- Limited hip and trunk power, which shifts the load to the elbow
- Previous elbow or shoulder pain in the same season
Who is most affected
Boys present more often than girls. The majority are affected in the dominant arm. Cricket fast bowlers, as well as baseball and softball throwers, feature in Australian clinics.
Typical symptoms
- Inner elbow ache with throwing or serving
- Reduced ball speed or accuracy
- Tenderness over the medial epicondyle and pain with resisted pronation
When to seek care
If pain appears during a season and does not settle within a week of rest. Seek urgent review after a sharp event with weakness or bruising.
How we diagnose
History and examination with strength and control tests. An X-ray may reveal apophyseal changes when symptoms persist. Ultrasound assists in some cases. MRI is seldom required.
Management
- Initial break from throwing and heavy forearm loading
- Strength for flexor–pronator, rotator cuff, scapular stabilisers, trunk, and hips
- Mobility for the thoracic spine and posterior shoulder
- Interval return‑to‑throw plan with technique coaching and workload caps
- Communication between family, coach, and clinician
Rehabilitation milestones
Phase 1 weeks 0–3: pain control, no throwing, gentle range and isometrics.
Phase 2 weeks 3–8: heavy slow strength for forearm, cuff, and scapula; trunk and hip power; conditioning without throwing.
Phase 3 weeks 8–12: begin interval throwing at low volume; progress distance and intensity by plan.
Phase 4 months 3–6: position‑specific skills and competition readiness.
Readiness to progress
- No pain with daily tasks and drills
- Forearm and external rotation strength within 90 per cent
- Throwing steps completed without next‑day soreness
Prevention
- Plan season volumes with rest days and deload weeks
- Build trunk and hip drive to reduce elbow load
- Avoid overlapping team commitments during busy terms
Australia snapshot
- Seen in cricket, baseball, and softball programmes
- Dominant arm involvement is the rule
- Boys are present more often in Australian youth sport clinics
Latest insights
Rest the plate early, then build the engine around it. Throwing returns smoothly when the lower body and trunk drive the motion.
Clear season plans reduce recurrence and protect the enjoyment of sport.
