Pediatric Tibial Tuberosity Avulsion Fracture

  • Etiology: Related to jumping injuries and most common in basketball and high jumping
  • Imaging Radiograph:
    — Ogden classification system is used to classify tibial tuberosity avulsion fractures
  • DDX:
  • Complications:
  • Treatment:
  • Clinical: Avulsion of tibial tubercle is uncommon when tibial physis is open as tibial physis is weakest point and most likely to fracture

Radiology Cases of Tibial Tuberosity Avulsion Fracture

Radiograph and CT of tibial tuberosity avulsion fracture
AP radiograph of the knee (left) shows a double density projecting over the lateral aspect of the proximal tibia. Lateral radiograph of the knee (middle) shows a moderate suprapatellar joint effusion and elevation of the tibial tubercle away from the tibia. Sagittal CT without contrast of the knee (right) shows a fracture line involving the tibial tubercle and extending superiorly into the tibial epiphysis.
