A Segond Fracture is an avulsion of a small chip of bone off the lateral side of the femur, commonly seen in association with an anterior cruciate ligament rupture. 

This very subtle bony avulsion indicates the likelihood of inadequacy of the anterolateral ligament, which has avulsed from its attachment to the femur.


Significance of a Segond fracture

The small avulsion chip used to be considered as an indicator of a torn anterior cruciate ligament (ACL), but nowadays it is generally accepted to be an indicator of a torn anterolateral ligament that occurs in association with ACL tears.
