Two cases of typical ochronotic arthropathy were reported.Case 1; A 70-year-old man had had a considerable pain in the large joints for about ten years and a gait disturbance for eighteen months. The dark pigementation was noticed in sclera and ear cartilage, and his urine turned dark when a strong alkali was added to it. The ragiological examination showed disc calcification and bamboo spine, characteristic sign of ochronotic arthropathy. And the shoulder, hip and knee joints showed marked osteoarthrosis, but not ankylosis.Case; A 71-year-old woman had low back pain and right caxalgia. The findings of sclera, ear cartilage and urine were the same as Case 1. The ragiological examination showed marked disc degeneration and calcification without vertebral fusion, and moderate osteoarthrosis in the right hip.
