Forearm series

The forearm series is comprised of an anteroposterior and lateral projection. The series examines the entire radius and ulna including articulations distally and proximal. Typically requested for mid shaft injuries, the forearm series is not a 'two-for-one' projection of the wrist and the elbow joint due to divergent beam artefact at both ends of the image 2


Forearm x-rays are indicated for a variety of settings including:

  • trauma 
  • bony tenderness
  • suspected fracture
  • obvious deformity
  • non-traumatic pain 
  • suspected foreign body 


Standard projections
  • AP
    • demonstrates the radius and the ulna in the natural anatomical position
  • lateral
    • projection 90° to the AP view
    • illustrates partial overlapping of the radius and ulna
Modified trauma projections
  • horizontal beam lateral
    • modified lateral projection that requires little to no patient movement
    • produces a diagnostic lateral projection without risking patient pain
