Knee MRI : Segond Fracture

Segond Fractures on MRI may only be seen as an area of bone marrow oedema rather than the classic fracture fragment seen on x-ray. It is not related to an iliotibial band avulsion and the area to look for it is posterior to the Ilio Tibial Band insertion. Here is a quick review of what it looks like and where to look for it.
