Segond fracture of the proximal tibia

  • The Segond fracture is an avulsion fracture involving the proximal tibia immediately distal to the lateral plateau. 
  • Described by Paul Segond in 1879, in cadaveric experiments
  • It is believed to be a cortical avulsion of the tibia at the site of insertion of the middle third of the lateral capsular ligament (LCL).
  • It has an association with tears of the anterior cruciate ligament (75%–100% of patients), meniscal tears (66%–75% of patients), damage to the structures of the posterolateral corner of the knee.
