This x-ray shows a widened growth plate with an irregular pattern on the metaphyseal side.

This is an x-ray of the same patient taken after treatment with calcium and vitamin D. The growth plate has been reduced to its normal width as the cartilage has begun to calcify. The margin is smooth and clean on the end of the ulna. The calcification bands are visible on both radius and ulna.
