Distal radius fracture
Author:
Mikael Häggström [notes 1]
In projectional radiography ("X-ray") of a distal radius fracture, the most important findings are displacement and whether there is intra-articular involvement.
Displacement
Dorsal or volar tilt
File:Dorsal tilt of distal radius fracture.jpg
Fracture with a dorsal tilt: Dorsal is left, and volar is right in the image.
The dorsal or volar tilt can be described by an angle from the axial plane of the radius, shown in red in the image at right, and goes between:[1]
- A line drawn between the distal ends of the articular surface of the radius.
- A line that is perpendicular to the diaphysis of the radius.
Sometimes, the diaphysis of the radius is hard to distinguish from the ulna, and a line between them (turquoise line) may be used instead.[2]
Although this is the standard definition of dorsal or volar tilt, the parameter can be interpreted by clinicians as being in relation to the normal anatomical position of the articular surface of radius (which normally has a volar tilt of 11° to 12°), and should therefore be specified as shown in report.
Report
- Any dorsal or volar tilt, the degree thereof, and that is it in comparison to the axial plane of radius (to avoid mixup with being in relation to the normal anatomical position)
- Any additional complicating factors such as being comminuted or otherwise displaced
- Other skeletal fractures, commonly a loose ulnar styloid process.
