case_images: Anteroposterior (A) and lateral (B) radiographs taken four months after knee injury and operative reattachment of the anterior and posterior cruciate ligaments. Arrows indicate early metaphyseal arrest lines in the femur and tibia.

case_images: Post-operative radiographs (Figures  1 and 2) show conventional metaphyseal femoral, fibular and tibial growth arrest lines, but also an intra-epiphyseal distal femoral epiphyseal 'arrest silhouette' (Figure  2C).
case_images: Anteroposterior (A,C) and lateral (B) radiographs taken six months (A,B) and thirty-one months (C) after knee injury and operation. Arrows indicate mature metaphyseal arrest lines in the femur, tibia and fibula. The anteroposterior view at thirty-one months after injury (C) shows the transverse metaphyseal tibial and femoral arrest lines to be far less marked (arrowed), and to have migrated away in parallel to the physes. The middle arrow indicates the marked intra-epiphyseal femoral growth silhouette.

case_images: This 8-year-old girl sustained a right-sided tibial spine fracture (Figure  3).
case_images: Anteroposterior (A) and lateral (B) radiographs nine months post-fixation showing proximal tibia and fibula transverse metaphyseal arrest lines and a distal femoral intraepiphyseal arrest silhouette.

case_images: Anteroposterior ankle radiograph showing the comminuted Salter-Harris three distal tibia fracture, with a depressed articular 'die-punch' fragment.

case_images: A 10-year-old girl suffered a comminuted distal tibial fracture after falling from a height (Figure  5).
case_images: Anteroposterior ankle radiographs at two (A) and seven (B) months after operative fixation. The growth arrest line (arrowed) has grown away in parallel from the physis.

case_images: Serial radiographs (Figure  6) demonstrate the arrest lines moving away over time in parallel from the physis, demonstrating the absence of growth arrest at this stage.
