From WikiSM

Other Names

The examiner's thumb applies pressure to the scaphoid tubercle while the subject's hand is moved from ulnar deviation to radial deviation[1]
A During the performance of the scaphoid shift test, the examiner applies pressure using their thumb to the scaphoid tubercle while the subject's hand is moved from ulnar deviation and slight extension to radial deviation and slight flexion. B Fluoroscopic view of a positive scaphoid shift test result, demonstrating subluxation of the proximal scaphoid from the scaphoid fossa of the distal radius (arrow)[2]

Purpose


Description

  • The patient is seated with arm resting on table
  • The examiner places their thumb on the scaphoid tubercle on the palmer side, other fingers placed on the distal radius
  • The other hand holds the patients hand at the metacarpals
  • The wrist is slightly extended with ulnar deviation
  • This position is then inverted to radial deviation and slight palmer flexion
  • During this maneuver, the examiner is applying constant pressure with their thumb on the scaphoid tubercle
  • Positive Test:
    • Dorsal shift or displacement of fracture fragment
    • When pressure is removed, fragment will spontaneously reduce
  • Compare with unaffected wrist
