1. Fracture distal radius for undergraduate Prof Dr Osama A Amin

2. Fracture distal radius Neutral ulnar variance.

3. Fracture distal radius (A) Negative ulnar variance. The articular surface of the ulna projects 5 mm proximal to the site of radiolunate articulation. (B) Positive ulnar variance. The articular surface of the ulna projects 8 mm distal to the site of radiolunate articulation.

4. Fracture distal radius Ulnar slant. The ulnar slant of the articular surface of the radius is determined, with the wrist in the neutral

5. Fracture distal radius Palmar inclination.
