Salter-Harris type II fractures are the most common physeal fractures that occur in children. The fracture line will include the physis and a portion of the metaphysis, leaving a triangular metaphyseal fragment intact, otherwise known as the Thurston Holland fragment.
Salter-Harris fractures are injuries where a fracture of the metaphysis or epiphysis extends through the physis. Not all fractures that extend to the growth plate are Salter-Harris fractures.
Approximately 75% of physeal fractures will be a Salter-Harris type II with 33-50% occurring at the distal radius. Other common fracture sites are the distal tibia, distal fibula and, phalanges 2,3.
Salter-Harris type II fractures describe a fracture that extends through the physis and into a portion of the metaphysis.
In reality, the majority of fractures that involve the physis have at least a small fragment of metaphysis associated with them and are therefore type II injuries.
- fracture through the physis
- Thurston Holland fragment
- angulation, displacement and rotation may occur
