The angle between the two lines is the angle of volar or dorsal tilt of the wrist. Measurement of volar or dorsal tilt should be made in true lateral view of the wrist because pronation of the forearm reduces the volar tilt and supination increases it. When dorsal tilt is more than 11 degrees, it is associated with loss of grip strength and loss of wrist flexion.
