Abstract:
Objective To study the X-ray signs of forearm and leg in skeletal fluorosis and its diagnostic value,aim at finding the easy examination parts.Methods One thousand four hundred and forty subjects were examined using developed shield,darkroom and other portable dedicated device combined with a small X-ray machine.A total of 384 cases were diagnosed skeletal fluorosis.All patients were divided into different groups and the time,degree and range of X-ray to the forearm and calf elbow,knee,and long bone were compared.Results The X-ray change in the forearm elbow was earlier than that of the leg knee,and trabecular bone change was the earliest indicator,197 cases and 157 cases,respectively,and the difference was statistically significant (x2 =28.006,P ＜ 0.01).Membrane ossification of forearm backbone was earlier than that of the leg,and most of them were degree Ⅰ photos,213 cases and 126 cases respectively.The difference was statistically significant (x2 =17.626,P ＜ 0.01).The direction of the interosseous membrane ossification was from the forearm radius to the ulna,then to the fibula and tibia,and was accompanied by changes in the aggravation of forearm.A variety of indicators were observed,especially the membrane ossification in bone and joint trabecular bone and the long bone was the most active,and the forearm was more sensitive,obviously than that of the calf.Conclusion In the X-ray screening or detection of endemic fluorosis,the forearm radiography is a simple,economical,and effective diagnostic method.
