Introduction Generic adolescent term for medial elbow injury can refer to a continuous spectrum of injuries to medial side of the elbow including medial epicondyle stress fractures ulnar collateral ligament (UCL) injuries flexor-pronator mass strains Epidemiology demographics younger patients are more likely to have apophysitis or avulsion injuries, rather than UCL sprains Pathophysiology due to repetitive valgus loading with throwing causing repetitive microtrauma to the immature skeleton causes tension overload of the medial structures Risk factors Greater than 80 pitches per game More than 8 months of competitive pitching per year Fastball speed > 85mph Continued pitching despite arm fatigue/pain Participating in showcases Presentation Symptoms elbow pain in throwing arm decreased throwing speed, accuracy, and distance Physical exam tenderness to palpation about medial elbow pain with valgus stress instability with valgus stress notes more severe involvement should be checked in varying degrees of elbow flexion to extension Imaging Radiographs recommended views AP/lateral elbow findings may show physeal widening may show fragmentation or avulsion of the medial epicondyle MRI will show increased edema of the medial epicondyle apophysis can be used to confirm UCL insufficiency Treatment Nonoperative rest, activity modifications, PT indication is the mainstay of treatment technique coach and parent education is critical to limit number of innings pitched per week use minimal immobilization to maintain elbow ROM Operative ORIF of medial epicondyle indication for medial epicondyle avulsion fractures UCL reconstruction indication for UCL disruption and insufficiency Technique Pediatric UCL reconstruction similar to adult treatment commonly using palmaris longus autograft Complications Ulnar nerve neuropathy Continued pain and instability Loss of motion Inability to return to same level of play

Examination reveals normal elbow range of motion. He is tender over the medial elbow to palpation. A dynamic ultrasound of his elbow shows no evidence of medial widening with valgus stress. His radiograph is shown in Figure A and an MRI is shown in Figure B. What is the most likely cause of his symptoms?
