Finger series

Last revised by Andrew Murphy on 23 Mar 2023

The finger series is comprised, conventionally of a posteroanterior, oblique and a lateral view. The series examines in detail the distal, middle and proximal phalanx as well as the interphalangeal, metacarpophalangeal and carpometacarpal joints. 

Note: the thumb (first digit) reviewed under the thumb series


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


Standard projection
  • PA view
    • typically performed with adjacent fingers in the field of view to ascertain what finger is being imaged 
    • displays the distal, middle and proximal phalanx in the PA (AP) position  
  • oblique view
    • the entire finger is displayed at roughly 45° to the PA projection
    • it has been proven to enhance the diagnostic accuracy of the finger series 2
  • lateral view
    • demonstrate the entire finger in the lateral position
    • excellent view to evaluate for dislocations and volar plate avulsions
