Distal radius x-ray: Difference between revisions

Latest revision as of 14:52, 14 October 2019

Checklist

Is there loss of normal anatomy (e.g. fracture displacement or angulation, loss of radial height)
Is there involvement of the radiocarpal or distal radioulnar joint?
Is there discontinuity of the articular surface or diastasis (separation) of the articular fragments?
Are high-risk features present (severe comminution, articular step-off >2 mm, fracture-dislocation)?

Specific Views

PA

Radial inclination (angle between line perpendicular to long axis of radius and line between radial styloid and ulnar corner of lunate fossa)
- Normal = 15-25 degrees
  - Often smaller with fracture
Radial height (Distance between distal tip of radial styloid and articular surface of the radius)
- Normal ~ 10-17mm
  - Often smaller with comminuted or impacted fracture
Ulnar variance (Distance between ulnar-side articular surface of radius and the ulnar carpal surface)
- Normally 1-2mm

Lateral

Palmar Tilt (angle between line perpendicular to long axis of radial shaft and line through the apices of the palmar and dorsal rims of the radius
- Normally 10o-25o
  - Often smaller with fracture

Oblique

May reveal intra-articular involvement not seen on other views
