Overview
Radiographic imaging is important in diagnosis, classification, treatment and follow-up assessment of distal radius fractures. The routine minimal evaluation for distal radius fractures must include two views - a postero-anterior (PA) view and lateral view.
X Ray
- Radiographic imaging is important in diagnosis, classification, treatment and follow-up assessment of distal radius fractures.[1][2][3][4][5][6][7]
- The routine minimal evaluation for distal radius fractures must include two views - a postero-anterior (PA) view and lateral view.
- Positioning for the x-rays:
- The posteroanterior view should be acquired with the patient’s elbow and shoulder at 90° and the forearm in neutral rotation.
- When the lateral view is acquired correctly, i.e., in the absence of relative pronation or supination, the pisiform bone should be superimposed on the distal pole of the scaphoid.
Posteroanterior View Inspection
Radial Length
- It is used when assessing shortening of the radius after fracture, can be obtained using the posteroanterior view.
- Method:
- Two lines are drawn perpendicular to the long axis of the radius, one at the tip of the radial styloid and the second at the ulnar border of the distal radial articular surface.
- Normally, this length is about 12 mm.
- Excessive radial shortening after fracture of the distal radius may be associated with tears of the triangular fibrocartilage complex (TFCC).
Radial Inclination
 |
- Method:
- Radial inclination is the angle between a line perpendicular to the central axis of the radius and a line connecting the radial and ulnar limits of the articular surface of the distal radius.
- The articular surface of the distal radius exhibits approximately 23° (range:13–30°) of normal radial inclination.
Ulnar Variance
- Ulnar variance, defined as neutral, positive, or negative, is evaluated on the frontal view.
- Method:
- Ulnar variance, according to the method of perpendiculars, is the vertical distance between two tangential lines both perpendicular to the long axis of the radius.
- One line is drawn at the level of the radial sigmoid notch and the second at the level of the lateral cortical margin of the distal ulna.
- With excessive radial shortening, ulnar positive variance will be present.
Radial translation ratio
- Method:
- The distal radioulnar joint gap is the distance between two longitudinal lines along the cortical rim of the sigmoid notch of the radius and the adjacent ulnar head.
- The fraction of the distal radioulnar joint gap relative to the radioulnar width of the proximal fracture fragment reflects the radial translation ratio.
- This ratio was is a significant risk factor of distal radioulnar joint instability following unstable distal radius fracture and indicates tears of the triangular fibrocartilage complex (TFCC).
Lateral View Inspection
Volar Tilt
 |
- The normal distal radius shows relative volar tilt.
- Method:
- Volar tilt is the angle between a line perpendicular to the central axis of the radius and a line connecting the dorsal and volar margins of the articular surface of the distal radius on the lateral view.
- Loss of the normal volar tilt can accompany fractures of the distal radius.
- Extreme dorsal angulation may be associated with injury to the TFCC.
Teardrop angle
- The volar rim of the lunate facet of the distal radius forms a teardrop shape along the distal, volar surface of the radius on the lateral view.
- Method:
- A teardrop angle can be acquired by drawing a line down the long axis of the radius that intersects a line drawn through the center of the lunate facet–teardrop.
- A normal teardrop angle is approximately 70°.
- This angle is used to determine whether there is persistent articular incongruity after reduction of a fractured volar rim fragment.
