Subchondral cysts were observed in the distal epiphysis of both radius and ulna. The 5th metacarpal bone of the left hand was short. b Bilateral hip joint spaces are markedly narrowed. Bilateral coxa vara deformity was observed. Bilateral femoral heads were flat, femoral necks were short. c The joint space was narrowed in both knees. d Chronic degenerative changes were observed in both hip joints. Coxa vara deformity, narrowing of the joint spaces, millimetric subchondral cysts on the femoral heads were observed. The changes were more prominent on the left side. Coxa magna deformity was detected in the left femur. e Fluid increase in the joint space and contrast enhancement consistent with synovitis were observed on the left side
