Extraarticular, wedge fracture

These wedge fractures are metaphyseal fractures of the distal tibia that can be further described as:

  • Having posterolateral impaction (classified by AO/OTA as 43A2.1)
  • Having an anteromedial wedge fracture (classified by AO/OTA as 43A2.2)
  • Having the wedge fracture extend into the diaphysis (classified by AO/OTA as 43A2.3)
Clinical assessment must include the condition of the soft tissues as well as the sensory and motor function of the foot structures. Special attention is given to any signs of a compartment syndrome.  Standard AP and lateral x-rays are taken. In case of doubt, CT-scans may be helpful to detect or exclude involvement of the articular surface.  For all distal tibia fractures, the fibula must be classified as intact, or fractured into two or multiple fragments.
