Fig 1.
Representative images of brick-tea type skeletal fluorosis by X-ray examination.
Normal (a) and (b): Normal forearm and shin. Mild (c) and (d): The interosseous membrane in the forearm or lower leg bone was mildly ossified with rough edges (arrows). Moderate (e) and (f): The radial crest and the border were enlarged; the interosseous membrane in the forearm or shin was ossified with serration or wave edge (arrows). Severe (g) and (h): The radial crest was enlarged and the border was obviously enlarged so that ulna and elbow joints presented severe degenerative changes; the interosseous membrane in the forearm or shin was obviously ossified with large shape (arrows).
