(c) severe, total closing motion tip of digit lacks one inch of touching palm and can extend to 45 degrees flexion, 9 percent.
B. Digits other than thumb.
(1) To rate any digit excluding the thumb, find the appropriate descriptive category in item A, then multiply the rating by the following factor for the involved digit:
(a) index finger, multiply by 0.6;

(c) ring finger, multiply by 0.25;
(d) little finger, multiply by 0.125.
(2) Total ankylosis of distal interphalangeal joint, multiply rating in unit (a) or (b) by multiplier for involved digit in subitem (1):
(a) optimum position, 5.5 percent;
(b) malposition, flexed 35 degrees or more, 8 percent.
