Endemic fluorosis may increase the severity of osteoarthritis in the knees. . . . Twelve patients (21.4%) with endemic fluorosis and eight control patients (20%) had grade 2 osteoarthritis, 16 patients (28.6%) with endemic fluorosis and three control patients (7.5%) had grade 3 osteoarthritis, and six patients (10.7%) with endemic fluorosis and one control patient (2.5%) had grade 4 osteoarthritis. The osteoarthritis severity was greater in the endemic fluorosis group. Osteophytes at the anterio
[A]rthopathy and arthritis affected a significant number of the (fluorosis) patients, resulting in functional disability. . . . The physical signs of brick-tea type skeletal fluorosis were elbow, shoulder and knee articular dysfunction, which was the most common pathology. X-ray examination revealed that the interosseous membrane ossification, tendon attachment calcification and articular degeneration were the causes of these functional disorders.
