Finger series
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
Indications
Finger x-rays are indicated for a variety of settings including:
- fractures
- dislocations
- foreign body localization
- scleroderma
- erosive arthritis
- traumatic injuries
- avulsion fractures
Projections
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
- lateral view
- demonstrate the entire finger in the lateral position
- excellent view to evaluate for dislocations and volar plate avulsions
