309     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 the AMA5, then convert each of those ratings into WPI ratings using Table 16-3 of AMA5. Combine those WPI ratings obtained from the AMA5 using the combined values chart (see Appendix 1).
    310     For ankylosis, the optimal or functional position is 20°-40° of flexion, 20°-50° of abduction and 30°-50° of internal rotation. Unless the shoulder has been arthrodesed, an assessment for ankylosis under this table would be rare.
