Triplane Fracture

  • Etiology: Salter-Harris Type IV fracture of distal tibia before closure of lateral physis
  • Imaging: sagittal fracture through epiphysis, axial fracture through physis, coronal fracture through metaphysis

Radiology Cases of Triplane Fracture

Radiograph and CT of triplane fracture
AP (left upper) and lateral (right upper) radiographs of the ankle show a sagittal fracture through the tibial epiphysis, an axial fracture through the physis, and a coronal fracture through the tibial metaphysis. This is better demonstrated on the coronal (lower left) and sagittal (lower right) CT 2D reconstructions without contrast of the ankle.
