Medial Apophysitis
Treatment
• Rest, Ice, NSAIDs
• PT?
• Gradual return (6-12 wks) to activity symptom free and exam WNL
• Modify throwing to minimize recurrence

• Sudden “pop”
• Pain medial elbow
• Inability to throw
• +/- ulnar nerve sxs
Mechanism medial tension UCL
• Flexor-Pronator contraction
Medial Epicondyle Avulsion
Physical Exam • Swelling, ecchymosis medially
• Acute tenderness at epicondyle
• Limited ROM
• Pain with resisted wrist flexion • Pain with valgus ? Instability
• Ulnar nerve involvement Beware ulnar nerve entrapment in fx

Medial Epicondyle Avulsion
• Poor ability to quantify disp on x-ray
• Pappas et al, JBJS 2010• Poor reliability
• Edmonds JBJS 2010• Anterior displacement!
Medial Epicondyle Avulsion
Treatment of choice?• 1) Long-arm cast x 4 wks
• 2) Hinged elbow brace x 6 wks
• 3) ORIF with pins, cast x 4 wks
• 4) ORIF with screw, early ROM
Medial Epicondyle Avulsion
Josefsson & Danielsson, AOS 1986
• 56 patients (7-17yrs)
• <15mm displacement
• Mean 35 year follow-up
• “Good” function
• 55% nonunited
• 20% stiffness
• 2% symptomatic instability

Medial Epicondyle Avulsion
• Ulnar Nerve Proximity
Medial Epicondyle Fracture
Why ORIF
• Stable fixation, early ROM, less stiffness
• Valgus stability and flexor pronator strength
• Avoidance of late deformity & ulnar neuropathy
• Nonunion reconstruction difficult
