Definition

Little League elbow is the result of repetitive stress to the growth plate on the inside of the elbow. The greatest stress occurs during the acceleration phase of throwing a baseball. Growing bones are easily injured because the growth plate is much weaker than the ligaments and muscles that attach to it. Kids with Little League elbow must take a break from all throwing for about 6 weeks. For pain and swelling, they can: Put ice or a cold pack on the elbow every 1–2 hours for 20 minutes at a time. This injury most often affects pitchers ages 9-14, though baseball players in other positions, as well as other overhead athletes such as volleyball players and football quarterbacks, may also be susceptible to little league elbow.

Young athletes should avoid breaking pitches, such as a curveball or slider, until after they are 14 years old. The skeletally immature elbow and shoulder cannot handle the repetitive forces and torque produced by these pitches. Nonsurgical treatments include rest and applying ice to the painful or swollen area of the elbow for a few days, as well as over-the-counter medications for pain and physical therapy. Once the condition clears, changing or refining throwing techniques may help prevent future injury.

Other Names

  • Little League Elbow
  • Medial Epicondyle Apophysitis
  • Medial Epicondyle Stress Fracture

Pathophysiology

  • By definition occurs in skeletally immature pediatric patients
    • In these patients, avulsion or physical injuries more common than ligamentous or tendon injuries
    • As growth plates fuse, these athletes develop other causes of medial elbow pain
    • The injury pattern depends on the developmental stage of the elbow
  • Occurs as a result of overuse or repetitive valgus stress placed upon the elbow
    • Causes a tension force to overload the medial structures
    • Produces tension along the medial elbow, shearing at the posterior elbow, and compression along the lateral elbow[4]

Causes

  • Sports
    • Overhead athletes
    • Throwing athletes
  • Seen during cocking, acceleration phases of pitching
  • Overuse can be classified into 4 stages:
    • Pain in the affected area after physical activity
    • Pain during activity without restricting performance
    • Pain during the activity that restricts performance
    • Chronic unremitting pain even at rest
  • Factors that contribute to overuse
    • Pitching mechanics
    • Pitch volume (>80 per game)
    • Pitch type (especially fastball)
    • Pitch duration (> 8 months per year)
    • Pitching when fatigued
    • Physical conditioning

Associated Conditions

  • Can occur if the disease progresses
    • Ulnar Collateral Ligament Injury
    • Medial Epicondylitis

Pathoanatomy

  • Osseous structures
    • Medial Epicondyle including medial epicondyle apophysis, of distal Humerus
    • Proximal Ulna
    • Humeroulnar Joint
  • Static stabilizers
    • Ulnar Collateral Ligament
  • Dynamic stabilizers
    • Common Flexor Tendon

Diagnosis

  • History
    • Typically in 9-12-year-old males
    • Almost universally insidious in nature with no acute trauma
    • Important to clarify sport, position, frequency, etc
    • Will complain of pain in throwing arm and loss of speed, accuracy, and/or distance
    • Pain is at the medial elbow
    • Sometimes stiffness, swelling, limited elbow extension, mechanical symptoms
  • Physical: Physical Exam Elbow
    • Tenderness to medial elbow
    • Swelling and effusion can be present
  • Special Tests
    • Elbow Valgus Stress Test: Should be painful, instability suggests more significant injury

Radiographs

  • Standard Radiographs Elbow
    • Diagnosis is primarily clinical
    • Often normal early on in disease process
  • Findings
    • Apophysitis: physeal widening, sclerosis, cortical irregularity
    • Epiphysiolysis: fragmentation or avulsion of the medial epicondyle

MRI

Treatment

Nonoperative

  • Indications
    • First-line therapy in virtually all cases
  • Relative rest
    • Discontinue offending activity, typically throwing until pain and tenderness resolve
    • Usually about 4-6 weeks
  • Physical Therapy
    • Begin when pain-free
    • Strengthen dynamic stabilizers of core, shoulder
    • Eventually throwing program as the athlete approaches RTP

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Orthopedic doctor, rheumatologist, or physiotherapist depending on cause.

What to tell the doctor

  • Write which joints hurt, swelling, morning stiffness duration, fever, injury, and walking difficulty.
  • Bring X-ray, uric acid, ESR/CRP, rheumatoid factor, or previous reports if available.

Questions to ask

  • Is this injury, osteoarthritis, rheumatoid arthritis, gout, infection, or another cause?
  • Which exercises, supports, or lifestyle changes are safe?
  • Do I need blood tests or X-ray?

Tests to discuss

  • Joint examination and range of motion
  • X-ray when chronic arthritis or injury is suspected
  • ESR/CRP, uric acid, rheumatoid tests when inflammatory arthritis is suspected

Avoid these mistakes

  • Do not ignore hot swollen joint with fever.
  • Avoid repeated steroid injections/tablets without a clear diagnosis and follow-up.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Avoid heavy lifting, sudden bending, and prolonged bed rest.
  • Use comfortable posture and gentle movement as tolerated.
  • Discuss physiotherapy, X-ray, or MRI only when clinically needed.

OTC medicine safety

  • For mild back pain, pain-relief medicine may be discussed with a doctor or pharmacist.
  • Avoid repeated painkiller use if you have kidney disease, stomach ulcer, uncontrolled blood pressure, or are taking blood thinners.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Back pain with leg weakness, numbness around private area, loss of urine/stool control, fever, cancer history, or major injury needs urgent care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider
Tests to discuss with doctor
  • Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
  • Relevant blood, urine, imaging, or specialist tests only after clinical assessment
Questions to ask
  • What is the most likely cause of my symptoms?
  • Which warning signs mean I should go to emergency care?
  • Which tests are really needed now?
  • Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Safe pathway to proper treatment

Care roadmap for: Little League Elbow

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
