297 The following tables assess impairments to range of motion of the elbows, including ankylosis:
a) Table 9.10.1a: Elbow – flexion/extension; and
b) Table 9.10.1b: Pronation and supination of forearm.
298 Loss of range of motion in each functional plane is measured from the neutral position. The range of motion is expressed as the two achievable limits of active motion in each direction through the normal range of motion. It is possible that the only motion that can be achieved is between two points on one side of the neutral position.
299 The WPI rating for restriction of motion in one direction is assessed according to the active motion than can be achieved in that direction. It is then added to the WPI rating for the active motion in the reverse direction.
300 Add the abnormal motion WPI rating for each direction of motion for both elbow flexion/extension and pronation/ supination. Where there is ankylosis, including after an arthrodesis procedure, the assessment should be made only under the ankylosis scale.
301 Where an arthroplasty procedure has been undertaken, refer to the AMA5. Assess the upper extremity impairment rating for abnormal motion and the upper extremity impairment rating for arthroplasty in accordance with AMA5, then convert each of those ratings into WPI ratings using Table 16-3 of the AMA5. Combine those WPI ratings obtained from the AMA5 using the combined values chart (see Appendix 1).
