Part 4.
.
- Radial inclination :-
_ Is the angle between the distal radial articular surface with respect to a line perpendicular to the shaft.
_ Normal values = 21 - 25°.
_ When this angle is reduced, be alert for a fracture (likely impacted).
.
- Radial length :-
_ Is the vertical distance between the radial styloid and radial rim of the distal ulna.
_ Normal values = 10 - 13 mm.
_ When the radial height is reduced (shortened radius), be alert for a fracture (likely impacted).
