May only show soft tissue swelling at lateral fibula

Salter-Harris I
See radiograph-negative ankle injury (peds)
Salter-Harris II
Removable ankle brace
Salter-Harris III (25%)
Require open reduction of any displacement
Tillaux fracture
Salter-Harris type III of the anterolateral portion of the distal tibia
ATFL avulses off the distal tibia
May need oblique view to distinguish from triplane fracture
Usually requires surgical reduction
Triplane fracture
Medial portion of distal tibia growth plate closes before lateral aspect
While normal, this causes 18-month period of vulnerability until lateral aspect closes
Planes
Plane 1: Lateral side of tibia through growth plate to fused medial aspect of physis
Plane 2: Sagittal through epiphysis
Plane 3: Coronal through distial tibial metaphysis
Imaging
Appears as Salter III on AP, Salter II on lateral
Management
CT to delineate injury
Ortho consult; closed reduction sufficient in most cases
