Talar head fractures are rare fractures that have a high frequency of co-existing foot fractures.
On this page:
Epidemiology
Talar head fractures account for ~5% (range 2.6-10%) of talar fractures 4.
Pathology
Talar head fractures are almost always associated with other foot fractures, frequently with peritalar fracture-dislocation and/or Chopart injuries 4.
Four types of talar fractures are described 3,4:
- impaction/compression fracture, often with significant comminution
- complete transverse
- shear fracture
- avulsion fractures
Radiographic features
The fracture may sometimes be difficult to identify on radiographs and CT may be necessary to identify the fracture line 4.
Complications
The incidence of avascular necrosis is low due to good vascularity, unlike talar neck fractures 4.
Treatment and prognosis
- non-displaced fractures: short leg cast and partial weight-bearing
- displaced fractures: open reduction - internal fixation (ORIF)
