Salter-Harris III fractures are physeal injuries that extend into the epiphysis and involve the articular surface.
In the distal tibia, simple fractures are classified as 43t-E/3.1.
An associated fibular fracture may have a different configuration and is classified separately.
This type of physeal fracture has a high risk of growth disturbance, nonunion, and subsequent osteoarthritis. Anatomical restoration of these fractures reduces these risks.
A CT scan may be required to assess the fracture pattern and articular surface displacement.
