Talar head fracture

Talar head fractures most commonly result from a compressive force with a plantar flexed foot.


Talar head fractures almost always involve the talonavicular joint, and associated dislocation/subluxation is common.

Two types of talar fractures are described :

  • compression fracture, often with significant comminution
  • shear fracture

Radiographic features

The fracture may sometimes be difficult to identify on radiographs and CT may be necessary to identify the fracture line.

The incidence of avascular necrosis is low due to good vascularity, unlike talar neck fractures.
