Ossification of the interosseous membrane of the leg

Last revised by Dr Daniel J Bell on 02 Jun 2022

Ossification of the interosseous membrane of the leg is considered a form of heterotopic ossification. It is typically seen as bridging ossification between the tibia and fibula.

Three types have been described.

  • type I: usually occurs after a syndesmosis ankle sprain
  • type II: usually from a tibial fracture
  • type III: by repetitive minor traumas to the leg
