313 Total loss of hand function is equivalent to amputation of the whole hand and attracts a WPI rating of 54%.
314 Table 9.14: Upper extremity function must not be used for amputations.
Table 9.12.1: Upper extremity amputations
| 54 | Amputation of thumb and all fingers through metacarpals. | | 56 | Amputation at wrist or between wrist and distal to bicipital insertion. | | 57 | Amputation from distal to deltoid insertion to bicipital insertion. | | 60 | Amputation of arm at deltoid insertion and proximally.<br>or<br>Amputation at shoulder. | | 70 | Forequarter amputation. |

9.13 Neurological impairments affecting the upper extremities
315 Sensory impairments due to digital nerve lesions alone are assessed under tables dealing with sensory losses in thumb and fingers:
a) Table 9.8.2a: Sensory losses in the thumb;
b) Table 9.8.2b: Sensory losses in the index and middle fingers;
c) Table 9.8.2c: Sensory losses in the little finger; and
d) Table 9.8.2d: Sensory losses in the ring finger.
316 Care must be taken to avoid duplicating impairment assessments for digital nerve sensory impairment with assessments for peripheral nerve sensory impairment. Assessments for digital nerve sensory impairment are assessed under Table 9.8.2a, Table 9.8.2b, Table 9.8.2c and Table 9.8.2d. Assessments for peripheral nerve sensory impairment are assessed under Table 9.13.1: Cervical nerve root impairment, Table 9.13.2a: Specific nerve lesions affecting the upper extremities – sensory impairment and Table 9.13.2b: Specific nerve lesions affecting the upper extremities motor impairment.
