Tillaux Fracture

  • Etiology:
    — Distal tibial growth plate fuses in medial to lateral direction making lateral aspect of distal tibia prone to avulsion injuries
    — Is a transitional fracture which occurs after medial tibial physis has fused but lateral physis is unfused
  • Imaging Radiograph:
    — Salter-Harris Type III fracture of anterolateral distal tibial epiphysis
    — Vertical lucency in distal tibial epiphysis
  • DDX:
  • Complications:
  • Treatment:
  • Clinical: In adolescents 12-15 years old

Radiology Cases of Tillaux Fracture

Radiograph and CT of Tillaux fracture
AP (upper left), mortise (upper right) and lateral (lower left) radiographs of the ankle show a lucency through the lateral aspect of the tibial epiphysis that is better demonstrated on the sagittal CT 2D reconstruction without contrast of the ankle (lower right)
