Foot (DP talus view)

Last revised by Andrew Murphy on 23 Mar 2023

The medial oblique axial talus view, also known as the Canale view, is a specialized projection of the talus bone, more specifically the talar neck.

This view is specifically indicated when assessing talar neck fracture and/or their follow-up. It is particularly useful to assess varus displacement 1,2. This projection is difficult to perform in the acute setting, however often utilized to assess both the effectiveness of reduction and the monitoring of osteonecrosis 2,3.

  • the patient may be supine or upright depending on comfort
  • the affected leg must be flexed enough that the plantar aspect of the foot is resting on the image receptor
  • the foot is everted 15° (the same as a medial oblique foot)
  • oblique, axial projection
  • centering point and tube position
    • midfoot
    • the tube is angled 15° from vertical
  • collimation
    • lateral to the skin margins
    • anterior to the midoot
    • posterior to the skin margins of the calcaneum

Clear undistorted view of the talus with clear visualization of the talar neck 

This projection is essentially a medial oblique foot with DP tube angulation. It is quite useful when performing follow-up imaging of talus fractures, and, if the patient can tolerate it (and CT is not an option) a great projection to use in the acute, suspected talus fracture, setting.
