Tillaux Fracture

  • Etiology: occurs after medial tibial physis has fused but lateral physis is unfused
  • Imaging: Salter Harris III fracture of lateral distal tibial epiphysis
  • Clinical: in adolescents, distal tibial growth plate fuses in medial to lateral direction, making lateral aspect of distal tibia prone to avulsion injuries

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)
