Salter Harris Classification

Question 1

SH Type 1

Answer 1

Represents isolated fracture through the growth plate.

Usually the radiograph appears normal, with the diagnosis being made clinically because of tenderness over the epiphyseal plate and soft tissue swelling.

Question 2

SH Type 2

Answer 2

This is a fracture through the displaced growth plate, which carries with it a corner of the metaphysis.

Most common epiphyseal injury, comprising approximately 75% of cases.

Question 3

SH Type 3

Answer 3

The fracture line is directed along the growth plate and then turns towards the epiphysis.

Most frequent site is the distal tibia.

Question 4

SH Type 4

Answer 4

Obliquely orientated, vertical fracture that passes through the epiphysis, growth plate and metaphysis.

The fracture fragment consists of a portion each of the metaphysis, growth plate and epiphysis.

The most common sites are the lateral condyles of the distal humerus in patients under 10 yrs., and the distal tibia in those over 10.

Question 5

SH Type 5

Answer 5

Least common and results from a compressive deformity of the growth plate.
