15 year old male presents to the emergency department after he has a fall from a skateboard. Xray below reveals a fracture. What classification of Salter-Harris fracture does the patient have?

A. Type I

B. Type II

C. Type III

D. Type IV

B. Type II- Your patient has a Type II Salter-Harris fracture above the physis. Type II is the most common type, representing 75% of physeal fractures, and it has a lower rate of growth arrest compared to types III and IV. Keep in mind that even if X-ray is negative, occult type I fractures are possible - if the patient has significant growth plate tenderness, splint and arrange for ortho follow up
