Triplane Fracture

General Considerations

  • The fracture involves the frontal, lateral, and transverse planes
  • It extends sagittally through the epiphysis, transversely through the epiphyseal plate and coronally through the distal tibial metaphysis
  • Occurs in older children/young adolescents in 18 months just prior to epiphyseal plate closure (about 12-15 years)
    • This is related to the manner in which the distal tibial epiphyseal plate closes
    • Children are susceptible to triplane fractures after closure of the medial epiphyseal plate and before closure of the lateral epiphyseal plate
