On AP view a curvilinear bony fracture is seen on the lateral aspect of the tibia reflecting a Segond fracture.
Best seen on lateral projection, an avulsion of the anterior tibial spine can also be seen.
Case Discussion
The anterior tibial spine is the tibial attachment of the anterior cruciate ligament. On plain x-ray, fracture of anterior tibial spine reflects anterior cruciate ligament avulsion fracture. Segond fracture is also an avulsion fracture seen at the lateral aspect of the tibial plateau, that is frequently associated with anterior cruciate ligament tear.
