There is widening of the epiphyseal plate with visible soft tissue swelling separating epiphyses and metaphyses. The metaphyses are broadened and cupped around the epiphyses, particularly of radius ulna and metacarpals. The provisional zone of sclerosis in the metaphyses is widened amd more instense than normal. The bone trabecular detail is blurred. A line of 'lucency' in the cortex on the medial side of the distal ulna on the right resembles sub-periosteal bone resorption.
