Elbow series

The elbow series is a set of radiographs taken to investigate elbow joint pathology, often in the context of trauma. It usually comprises an AP and lateral projection, although other non-standard, modified projections are utilised for specific indications.


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

  • trauma
  • bony tenderness
  • suspected fracture of the proximal radius and ulna
  • suspected fracture of the distal humerus
  • radial head dislocations
  • obvious deformity
  • detecting joint effusions
  • arthritis
  • infection


Standard projections
  • AP
    • ​demonstrates distal humerus, proximal ulna, and radius
    • shows both the medial and lateral epicondyles in profile
  • lateral
Modified trauma projections
  • horizontal beam lateral
    • modified lateral projection that requires little to no patient movement
    • ​produces a diagnostic lateral/AP projection without risking patient pain
