Elbow – extended lateral canine X-ray positioning guide

 

Positioning

  • Position dog in lateral recumbency, with leg to be radiographed against plate
  • Pull upper leg back and secure
  • Ensure elbow is extended to approximately 110°
  • Use cotton wool or foam pads to ensure radius and humerus are lying parallel to plate
  • Centre over humeral condyle and collimate to 1/3 of the way along radius/ulna distally and 1/3 of the way along humerus proximally
  • You may need to use ties or sand bags to ensure leg remains correctly extended
  • Ensure L/R marker in primary beam.

What to look for 

  • Ensure condyles are superimposed. 

Top tips

  • Cotton wool is great for lateral elbow positioning, as can be shaped to provide correct level of support
  • Ensure the carpus is also orientated lateromedially; this helps position the elbow correctly.
