y amputation, sensory loss, and abnormal motion as described above.Note: If an amputation affects the measurement of abnormal motion, thenonly the amputation impairment is given. For example, amputationproximal to the interphalangeal joint will affect measurements of adductionand opposition. Impairment is given only for the amputation.Combine the impairment values using the Combined Values Chart toascertain impairment of the thumb.Use Tables 1, 2, and 3 to relate thumb impairment to impairments of thehand, upper extremity, and the whole person.Example: Thumb amputation impairment of 30%, sensory impairmentof 10%, abnormal motion impairment of 10%:30% combined with 10% = 37%;37% combined with 10% = 43% thumb impairment.This is equivalent to 17% impairment of the hand, 15% impairment ofthe upper extremity, and 9% impairment of the whole person.3.1d FingersAmputation
