What Is Little League Elbow?
"Little League elbow" is the common name for medial apophysitis — an overuse injury to the growth plate on the inside of a young pitcher's elbow. Every time a pitcher throws, the muscles and ligaments on the inside of the elbow pull hard on a small piece of bone that hasn't finished fusing yet. Do that too many times without enough rest, and the growth plate becomes inflamed, painful, and in serious cases, can fracture or pull away from the bone.
It almost exclusively affects pitchers ages 8–15, while the growth plates are still open. The good news: caught early and managed properly, it heals completely. Caught late, it can end a season — or a career.
Warning Signs Every Parent Should Know
- ⚠Pain on the inside of the elbow during or after throwing
- ⚠A sudden drop in velocity or accuracy
- ⚠Trouble fully straightening the arm
- ⚠Swelling or tenderness on the inner elbow
- ⚠Reluctance to throw — especially in a kid who usually loves it
- ⚠Pain that goes away with rest but comes right back when throwing resumes
If you see any of these, stop throwing immediately. Continuing to pitch through inner-elbow pain is the single fastest way to turn a 4-week recovery into Tommy John surgery.
Why It Happens
Little League elbow is almost always an overuse injury — not a single bad throw. The research is consistent on the biggest risk factors:
- Pitching more than the recommended age-based pitch count
- Not taking the required rest days after an outing
- Pitching year-round with no real off-season
- Throwing breaking balls (curveballs, sliders) before puberty
- Pitching for multiple teams in the same season
- Pitching while fatigued — the #1 predictor of arm injury
Notice the pattern: every single one is a scheduling and workload problem. That's why it's so preventable — and why tracking throws in your head or on a sticky note isn't enough.
How a Weekly Plan Prevents It
Pitcher Plan was built specifically to solve the workload problem behind Little League elbow. Instead of guessing whether your pitcher threw too much this week, you get a structured 7-day plan that builds in:
- Pitch-count limits aligned with age-based arm-care guidelines
- Mandatory rest days after every high-intensity outing
- Progressive intensity — light throws on recovery days, peak effort on game day, complete rest at week's end
- Visibility across every pitcher on a roster so coaches never accidentally overwork the same arm
The result: no surprise overuse, no "I didn't realize he'd already thrown 60 pitches Tuesday" — and dramatically lower risk of the doctor's call.

Recovery: What to Do If Your Pitcher Already Has It
- Stop throwing — immediately. No "just one more inning." No bullpens. No long toss. Complete shutdown.
- See a sports medicine doctor. X-rays may be needed to rule out a growth-plate fracture.
- Rest 4–6 weeks minimum. Most cases need at least a month with zero throwing.
- Start a structured return-to-throw program. Begin with short, light tosses and progress gradually — never jump straight back to bullpens or games.
- Rebuild with a real weekly plan. The injury came from a workload problem; recovery without fixing that workload guarantees a re-injury.
Frequently Asked Questions
What is Little League elbow?
Little League elbow (medial apophysitis) is an overuse injury to the growth plate on the inside of a young pitcher's elbow. Repeated throwing — especially without enough rest — pulls on the growth plate and causes pain, swelling, and in serious cases, fragmentation of the bone.
What are the warning signs?
Pain on the inside of the elbow during or after throwing, loss of velocity, a drop in accuracy, reduced range of motion, swelling, or a pitcher who suddenly doesn't want to throw. Any of these warrant immediate rest and an evaluation.
How long does Little League elbow take to heal?
Mild cases typically need 4–6 weeks of rest from throwing, followed by a gradual return-to-throw program. More advanced cases can require 3+ months and physical therapy. The earlier you catch it, the shorter the recovery.
Can Little League elbow be prevented?
Yes — the vast majority of cases are preventable. The biggest risk factors are exceeding age-based pitch counts, skipping required rest days, pitching year-round without an off-season, and throwing breaking pitches too young. A structured weekly plan that manages all of these is the single most effective prevention tool.
When should we see a doctor?
If elbow pain persists more than a few days of rest, if there's visible swelling, if your pitcher can't fully straighten the arm, or if pain returns as soon as throwing resumes — see a sports medicine doctor before any further throwing.
