Medial epicondyle fracture (peds)

Background

• Not true Salter-Harris fx (apophysis, not physis, is involved)
• 50% assoc w/ elbow dislocation

Diagnosis

• Displacement of medial epicondyle ossification center
• May become entrapped w/in elbow joint
• Use CRITOE to determine if bone in joint is medial epicondyle or nl trochlear oss center
  • If think is trochlear but cannot see medial epicondyle fragment is medial epicondyle
    • (Medial epicondyle normally ossifies before the trochlea)
• Fat pad sign not usually present because most injuries are extra-articular
