Segond fractures: not necessarily pathognemonic of anterior cruciate ligament injury in the pediatric population.

Initially described following cadaveric studies in the late 19th century by Dr. Paul Segond, the Segond fracture is now widely accepted as a pathognemonic radiographic marker of anterior cruciate ligament injury. This fracture in a skeletally immature 16-year-old was not seen with an anterior cruciate ligament injury, but with a Salter-Harris type IV fracture of the tibial plateau. A nonweightbearing knee immobilizer with the leg in full extension was used for 6 weeks. Recovery was uncomplicated, and range of motion and weightbearing began at 6 weeks.
