Toes (AP view)

Dr Henry Knipe and Sarah Gorton et al.

Toes AP view is part of a three view toe series and includes the phalanges and the toe(s) of interest and the distal half of the associated metacarpals.

  • the patient can be either supine or be sitting upright on the table
  • knee should be flexed so the plantar surface of the foot makes contact with the detector
  • AP projection
  • centring point
    • x-ray beam centred to the metatarsophalangeal joint in question
    • the beam is to be perpendicular to the detector
  • collimation
    • collimate to include toe(s) of interest and at least part of the toe either side laterally
    • anterior to the skin margins of the most distal toe(s) of interest
    • posteriorly include at least the distal half of the metacarpal(s)
  • orientation
    • portrait
  • exposure
    • 50-55 kVp
    • 2-4 mAs
  • SID
    • 100 cm
  • grid
    • no
  • toe(s) of interest should be seen independently with no overlapping of soft tissues.
  • no rotation should be present, the shafts of the phalanges and metatarsals should appear equal on either side

The bases of the metatarsals are the most reliable rotation indicator on the AP view.

If the foot is over rotated externally, the metatarsal bases will be heavily superimposed.

Over rotation internally will open up the metatarsal bases. The resulting image will bea a close resemblance to the medial oblique projection.

In trauma, the patient may not be able to flex the affected knee to the desired angle. In this case, a triangular wedge can be placed under the foot.
