A Fifty-year old man. He visited our clinic due to bilateral shoulder pain and left knee pain. Black-brown pigmentations were observed on the conjunctiva bulbi and the auricle. Plain X-ray films showed severe osteoarthritic changes of both shoulders. Ranges of motion of the shoulder were 100 degrees of flexion in the right shoulder, 80 degrees in the left shoulder, 15 degrees of external rotation in the right shoulder, 0 degree in the left, 4th lumbar vertebra of internal rotation in both shoulders. The preoperative JOA scores were 55 points in the right shoulder and 78.5 points in the left, respectively. Total shoulder arthroplasties were performed on bilateral shoulder. The JOA scores revealed 90.5 points in the right shoulder at 55 months after the surgery and 91 points in the left at 62 months after the surgery, respectively. Although the cause of this disease could not be cured, but the mid period clinical results of total shoulder arthroplasty are excellent.
