Segond fracture – small avulsed bone fragment from the lateral margin of the tibial plateau. Avulsion at this location is the result of excessive varus stress on the lateral joint capsule. It is a small but important fracture as it has a very high association with internal derangement of the knee, particularly anterior cruciate ligament tear (right image) which is present in more than 75% of cases.
