14-Year-Old Pitcher with Medial Elbow Pain
A 14-year-old right-handed baseball pitcher complains of medial right elbow pain that began during a tournament three days ago. He plays for a school team and a travel team; in the past 7 days he pitched 95 pitches on Saturday and 45 on Sunday, and he threw two bullpen sessions midweek. Pain is localized to the medial epicondyle and worsens with throwing. He has full elbow range of motion, no swelling, and no ulnar nerve symptoms. Valgus stress at 30 degrees of flexion reproduces pain without laxity. Grip strength is normal. Radiographs show an open medial epicondylar apophysis without fracture. He wants to pitch in a regional tournament in 6 days; his coach asks you to tape it and let him go. His parents are worried about losing a college scholarship opportunity.
1. What is the likely diagnosis and which risk factors in this history matter most?
Read the worked answer
The likely diagnosis is medial epicondyle apophysitis, often called Little League elbow, an overuse injury of the open growth plate. The medial epicondyle is a traction apophysis subjected to valgus stress during the late cocking and acceleration phases. Risk factors include pitching while fatigued, pitching for multiple teams, insufficient rest, high pitch counts, throwing breaking balls, and year-round play. The absence of laxity and a normal neurovascular examination are reassuring, but apophysitis can coexist with ulnar collateral ligament injury. Radiographs showing an open apophysis without fracture are common; comparison views may help but are not always needed. Do not diagnose simple tendonitis or tape and continue. The key is to remove the offending load and protect the physis. Red flags include an acute pop, swelling, locking, ulnar nerve symptoms, or inability to throw at all.
2. What is your immediate management, and how do current youth pitch-count and rest rules apply?
Read the worked answer
He should not pitch in 6 days. Remove him from throwing immediately; relative rest from overhead throwing for at least 2-4 weeks, with pain-free range of motion and strength before a graduated throwing program. Use current Pitch Smart guidance for age 13-14: maximum 95 pitches per day; required rest after 66 or more pitches is 4 days, after 51-65 is 3 days, after 36-50 is 2 days, after 21-35 is 1 day, and after 1-20 is 0 days. He threw 95 on Saturday and 45 on Sunday, which violates consecutive-day and rest rules, and he added two bullpens. Educate the parents and both coaches; one team must own the pitch count. No maximum-effort radar-gun throwing, no showcases, and no breaking balls until symptoms resolve. Reassess in 2 weeks; if pain persists or acutely worsens, obtain MRI and refer to a sports medicine physician. Clearance must be criteria-based, not tournament-based.
3. Design a prevention and conditioning program for the next season.

Prevention should include a written pitch-count log shared by the school and travel teams; 3-4 months off from overhead throwing per year, with at least 2-3 months away from pitching; no pitching on consecutive days and no playing for multiple teams in the same season; a proper warm-up and throw-to-warm-up progression; and recovery after throwing. Strength and conditioning should target scapular stabilizers, rotator cuff, core, and lower body. Address throwing mechanics with a qualified coach, avoid early specialization and year-round baseball, and support sleep and nutrition. The athlete and parents should understand that the scholarship goal is better served by long-term health than by pitching through apophysitis. Document the plan and provide written return-to-throw criteria. Coordinate with the school athletic trainer and physician; if the coach pressures clearance, refer back to the medical team.
