Lateral tibial plateau partial fusion versus fracture. Sagittal and coronal PD images in three teens. a Normal partial closure of proximal tibial physis: similar to the distal tibial physis at the ankle, the lateral margin is last to fuse completely (arrow). Note the intact ACL. b Lateral tibial plateau fracture. On close inspection, the transverse low-signal band representing fracture (arrow) is slightly above the physis. Note also the corresponding femoral condylar impaction fracture (arrowhead). c Pseudo-fracture. On the coronal image, a transverse line just above the physis (arrow) resembles a fracture. On sagittal image, this corresponds to a point (circled), representing a vascular channel. Note the lack of visible ACL fibres, and the lateral femoral condyle impaction fracture (arrowhead)
