What Is Radial Length

Radial height (also known as radial length) is the distance between two lines drawn perpendicular to the long axis of the radius on the AP projection from the apex of the radial styloid and level of the ulnar aspect of the articular surface.

How do you measure radial shortening?

In conclusion, shortening is best determined by measuring the distance from distal radial surface to distal ulnar surface, although rarely this may be unsuitable. Fractures involving the ulnar styloid, impaction, and radial tilt make other methods less suitable.

What is radial angle?

The radial inclination is a measurement made on the AP projection of the wrist as an angle of the distal radial surface with respect to a line perpendicular to the shaft. A normal range is considered at around 21-25° 5. It can increase in the setting of certain fractures.
