Today’s video post is on MRI of Segond Fracture which is one of the injuries associated with ACL tears. We look at where to look, what to look for and how to report it.
Segond Fractures are fractures of the lateral tibial plateau often associated with ACL tears. It’s thought to be related to the tibial insertion of the anterolateral ligament. However, this ligament is not distinctly identified on MRI, and the best landmark is to look immediately posterior to the ITB insertion.
View the video to see how you can use a structured way to easily diagnose a Segond fracture on MRI.
A Segond fracture is an avulsion fracture of the lateral tibial plateau at the site of attachment of the Anterior Longitudinal Ligament (ALL). It is strongly associated with an underlying anterior cruciate ligament (ACL) tear.
Key MRI findings include a a step or break in the black cortical line, bony avulsion fragment at the lateral tibial plateau and in the acute stage bone marrow edema.
A Segond fracture typically results from internal rotation and varus stress to the knee. This mechanism puts excessive tension on the lateral capsular ligament, leading to the avulsion at the site of attachment of the Anterior Longitudinal Ligament (ALL).
