Pediatric Overuse Injuries — growth plates are not adult tendons
- Scale of the problem: overuse injuries account for ~50% of all youth sport injuries (DiFiori et al., AMSSM Position Statement, Br J Sports Med 2014)
- Why it differs from adults: open growth plates direct repetitive load to the apophysis — the same mechanism that causes tendinopathy in adults causes apophysitis in young athletes
- Top syndromes: Osgood-Schlatter (tibial tubercle, ages 10-15), Sever's disease (calcaneal apophysitis, ages 8-14), Little League Elbow (medial epicondyle in young throwers)
- Dominant modifiable risk: early single-sport specialization before age 12 (Brenner et al., AAP Clinical Report, Pediatrics 2007)
- First step, not full rest: reduce the specific sport's volume by 50-70%; prevention = ≥1 sport-free day weekly and 2-3 sport-free months yearly (AMSSM)

Osgood-Schlatter, Sever, Little League Elbow — these are not "growing pains". They are growth-plate injuries that demand a sport-specific approach for the young athlete.
Why pediatric overuse injuries are different
In plain language: Children have open growth plates, so the same repetitive load that causes tendinopathy in an adult instead injures the apophysis, the tendon-to-bone insertion that has not yet fused. This produces apophysitis at the growth plate. Per the AMSSM position statement, overuse injuries account for about 50% of all youth sport injuries.
Per the AMSSM (American Medical Society for Sports Medicine) position statement by DiFiori et al. (Br J Sports Med, 2014 — DOI: 10.1136/bjsports-2013-093299), overuse injuries account for approximately 50% of all sports injuries in children and adolescents. The key difference from adults: the presence of growth plates — active cartilaginous structures that have not yet fused to bone.
Where repeated overload causes tendinopathy in an adult, the same load in a young athlete is directed to the apophysis — the tendon-to-bone insertion that has not yet ossified. The result: apophysitis — inflammation and injury at the growth plate. The same mechanism produces different pathologies depending on body location.
The Brenner et al. review (Pediatrics, 2007 — DOI: 10.1542/peds.2007-0887 — AAP Clinical Report) identified early single-sport specialization as the dominant risk factor. A child who specializes in a single sport before age 12 is at significantly increased risk of overuse injuries and burnout. Activity diversification is evidence-based protection.
The most common youth overuse syndromes
In plain language: The most common youth overuse syndromes are Osgood-Schlatter at the tibial tubercle (ages 10-15), Sever's disease at the calcaneal apophysis (ages 8-14), Little League Elbow at the medial epicondyle (ages 9-14), Sinding-Larsen-Johansson at the inferior patella (ages 10-14), spondylolysis at the L5 pars interarticularis, and Iselin disease at the 5th metatarsal base.
| Syndrome | Typical age | Site | Typical trigger |
|---|---|---|---|
| Osgood-Schlatter | 10-15 | Tibial tubercle | Running, jumping, football, basketball |
| Sever's disease | 8-14 | Calcaneal apophysis | Football, running, sport in cleats |
| Little League Elbow | 9-14 | Medial epicondyle (UCL apophysis) | Baseball, softball, repetitive throwing |
| Sinding-Larsen-Johansson | 10-14 | Inferior pole of patella | Jumpers, dancers |
| Spondylolysis | 10-15 | Pars interarticularis (L5) | Gymnastics, lacrosse, cricket |
| Iselin disease | 9-14 | Base of 5th metatarsal | Football, running |
Clinical evidence — official position statements
DiFiori JP et al. — AMSSM Position Statement (Br J Sports Med, 2014 — DOI: 10.1136/bjsports-2013-093299) — Overuse injuries are ~50% of youth sport injuries. Modifiable risk factors: early specialization, excessive training volume, inadequate recovery, rapid growth. Evidence-based recommendation: at least one sport-free day per week, and at least 2-3 sport-free months per year from the specific sport.
Brenner JS et al. — AAP Clinical Report (Pediatrics, 2007 — DOI: 10.1542/peds.2007-0887) — American Academy of Pediatrics position statement. Documented that children are participating in increasingly intensive sport, sometimes simultaneously on multiple teams. Recommendations: early identification of at-risk children, family counseling on balance and load, awareness of burnout signs.
Signs to watch as a parent
In plain language: Watch for pain that begins after a game or training rather than only during effort, pain that worsens across a season, a drop in performance, a change in walking or running pattern such as a slight limp, mood or motivation changes that can signal burnout, and a child quietly asking to skip practices.
- Pain that begins after a game or training — not just during effort.
- Pain that worsens through a season — starts mild and intensifies in October-November for summer-sport athletes.
- Performance decline — slower, less energetic, "doesn't run like before".
- Walking or running pattern change — slight limp, "weird" pattern that wasn't there.
- Mood or motivation change — sign of burnout.
- Child requesting to stop or "casually skip" practices — way of expressing pain.
5 evidence-based prevention rules
In plain language: Five evidence-based rules from the AMSSM: avoid early single-sport specialization before age 12, schedule sport-free time of at least one day weekly and 2-3 months yearly, follow age-appropriate load rules such as baseball pitch counts, progress training volume by no more than 10% per week, and add a complementary fitness program with core and neuromuscular work.
- Avoid early specialization — children should sample diverse sports until at least age 12. AMSSM recommendation.
- Sport-free time — at least one day per week, at least 2-3 months per year off the specific sport.
- Age-appropriate load rules — pitch counts in baseball (Little League rules), time limits at certain ages in football.
- Gradual load progression — no more than 10% increase in weekly volume. Concept applies to children too.
- Complementary fitness program — core stability, scapular stability, neuromuscular work. Strengthen the defenses before they break.
When to worry immediately
- Night pain that wakes the child — oncological screen
- Acute swelling after trauma — concern for apophyseal avulsion or fracture
- Significant weakness or numbness — neurological evaluation
- Fever + pain + swelling — concern for infection (osteomyelitis)
- Child stopping mid-game crying — sometimes acute injury masked as "babying"
Child complaining of pain? Accurate diagnosis prevents long-term damage
Untreated apophyseal injuries can become persistent structural problems. A 50-60 minute professional assessment identifies the type, sets the pathway, and recommends sport continuation parameters.

Clinical information · Recovery TLV
WHAT IT IS: Pediatric and adolescent overuse injuries form a clinical category distinct from adult overuse injuries because growth plates (apophyses, physes) remain open and biologically active. Repetitive load that causes tendinopathy in adults causes apophysitis in young athletes. DiFiori JP et al. (Br J Sports Med, 2014, DOI:10.1136/bjsports-2013-093299 — AMSSM Position Statement) found overuse injuries account for ~50% of all youth sport injuries.
COMMON SYNDROMES: Osgood-Schlatter (tibial tubercle, ages 10-15), Sever's disease (calcaneal apophysitis, ages 8-14), Little League Elbow (medial epicondyle in young throwers), Sinding-Larsen-Johansson (inferior patellar pole), Spondylolysis (pars interarticularis stress fracture), Iselin disease (5th metatarsal base).
RISK FACTORS: Early sport specialization before age 12 is the dominant modifiable risk factor (Brenner JS et al., Pediatrics, 2007, DOI:10.1542/peds.2007-0887 — AAP Clinical Report). Other factors: excessive training volume, inadequate recovery, rapid growth, technique progression mismatch.
HOW WE TREAT IT: Diagnostic-specific. For apophysitis: relative load reduction (50-70%, not full cessation), targeted strengthening of upstream muscle groups, biomechanical correction, gradual return-to-sport. For stress fractures: imaging confirmation then bracing/rest before progressive loading. For UCL stress in young throwers: pitch count limits and functional retraining.
FAMILY GUIDANCE: Per AMSSM/AAP: at least one sport-free day weekly; at least 2-3 sport-free months yearly; avoid single-sport specialization before age 12; observe pitch counts and age-appropriate load rules; monitor for burnout signs.
RED FLAGS: Night pain (oncological screen); acute swelling after trauma (apophyseal avulsion or fracture); significant weakness or numbness (neurological); fever with pain and swelling (osteomyelitis); child stopping mid-game crying (sometimes acute injury masked as "babying").
