Segond fracture = avulsion of the anterolateral aspect of the lateral tibial plateau
Mechanism - internal rotation of tibia + varus stress
Originally postulated - avulsion of the lateral capsular ligament,
Recent MR study suggests - it occurs at the distal attachments of the iliotibial tract or Lateral Collateral Ligament. (ref: CT and MRI of the Whole Body, Fifth Edition, John R. Haaga)
Most common ASSOCIATED injury - ACL tear (75-100%)
2nd MC - Meniscal tear (medial or lateral, mostly posterior horn)(66-75%).
