OAR 436-035-0030: Amputations in the Upper Extremities

(1) Loss of the arm at or proximal to the elbow joint is 100% loss of the arm. (2) Loss of the forearm at or proximal to the wrist joint is 100% loss of the forearm. (3) Loss of the hand at the carpal bones is 100% loss of the hand. (4) Loss of all or part of a metacarpal is rated at 10% of the hand. (5) Amputation or resection (without reattachment) proximal to the head of the proximal phalanx is 100% loss of the thumb. The ratings for other amputation(s) or resection(s) (without reattachment) of the thumb are as follows (6) Amputation or resection (without reattachment) proximal to the head of the proximal phalanx is 100% loss of the finger. The ratings for other amputation(s) or resection(s) (without reattachment) of the finger are as follows: (7) Oblique (angled) amputations are rated at the most proximal loss of bone. (8) When a value is granted under sections (5) and (6) of this rule which includes a joint, no value for range of motion of this joint is granted in addition to the amputation value. (9) Loss of length in a digit other than amputation or resection without reattachment (e.g., fractures, loss of soft tissue from infection, amputation or resection with reattachment, etc.) is rated by comparing the remaining overall length of the digit to the applicable amputation chart under these rules and rating the overall length equivalency.
