Abstract
Workers of electrolytic departments at the Novokuznetsk aluminum plant were found to suffer not only from fluorosis (28.2) per cent), but also from degenerative-dystrophic affection of the skeleton (87.7 per cent). The workers of a control group who were not exposed to a chronic action of fluorine compounds the degenerative-dystrophic lesions of the skeleton are encountered on much rarer occasions (58.1 per cent). In workers of the aluminum plant there prevailed the affection of joints in the upper extremities, largely of a symmetric nature. Of decisive influence on the development of degenerative-dystrophic lesions of the skeleton was the service-record at the plant. A careful statistical analysis of the frequency of skeletal degenerative-dystrophic lesions in workers with fluorosis and in those who only had to deal with fluorides showed fluorosis to be of no significance in the development of degenerative-dystrophic affections of the joints and the spine.

X-ray diagnosis of fluorine-associated arthropathy
I. Pathological basis and X-ray signs of fluorine-associated arthropathy Long-term uptake of excessive fluorine may cause pathological changes of bone structure and bone periphery; furthermore, animal experiments and epidemiological investigations demonstrate that fluorosis may cause necrosis, degeneration and ulceration of articular cartilage, and also cause necrosis of subchondral bones, leading to

Ancient and recent evidence of endemic fluorosis in the Naples area
Endemic fluorosis induced by high concentrations of natural fluoride in groundwater and soils is a major health problem in several countries, particularly in volcanic areas. The early stages of skeletal fluorosis, a chronic metabolic bone and joint disease rarely considered in palaeopathological diagnoses, are often misdiagnosed in endemic areas. In

Skeletal fluorosis from instant tea
INTRODUCTION: Skeletal fluorosis (SF) can result from prolonged consumption of well water with >4 ppm fluoride ion (F(-); i.e., >4 mg/liter). Black and green teas can contain significant amounts of F(-). In 2005, SF caused by drinking 1-2 gallons of double-strength instant tea daily throughout adult life was reported in

The therapeutic effect of acupuncture for treatment of joint pain of skeletal fluorosis
Objective: To observe the clinical therapeutic effect of acupuncture for joint pain of skeletal fluorosis. Methods: Ninety-six patients with skeletal fluorosis joint pain were randomly allocated to filiform needle group(33 cases), heat needle group (32 cases) and caltrate group(31 cases); the clinical therapeutic effects of three groups were measured by visual

[Two cases of skeletal fluorosis in the hand].
Skeletal fluorosis is well known, particularly in the spine, pelvis and forearm. However, the hand may also be involved. The authors report two cases of this site in endemic areas in Senegal, after ingestion of large amounts of fluoride in the water. Fluorosis consisted of deforming metacarpal and phalangeal osteoperiotitis in one case

Fluoride & Osteoarthritis
While the osteoarthritic effects that occurred from fluoride exposure were once considered to be limited to those with skeletal fluorosis, recent research shows that fluoride can cause osteoarthritis in the absence of traditionally defined fluorosis. Conventional methods used for detecting skeletal fluorosis, therefore, will fail to detect the full range of people suffering from fluoride-induced osteoarthritis.

Skeletal Fluorosis: The Misdiagnosis Problem
It is a virtual certainty that there are individuals in the general population unknowingly suffering from some form of skeletal fluorosis as a result of a doctor's failure to consider fluoride as a cause of their symptoms. Proof that this is the case can be found in the following case reports of skeletal fluorosis written by doctors in the U.S. and other western countries. As can be seen, a consistent feature of these reports is that fluorosis patients--even those with crippling skeletal fluorosis--are misdiagnosed for years by multiple teams of doctors who routinely fail to consider fluoride as a possible cause of their disease.

"Pre-Skeletal" Fluorosis
As demonstrated by the studies below, skeletal fluorosis may produce adverse symptoms, including arthritic pains, clinical osteoarthritis, gastrointestinal disturbances, and bone fragility, before the classic bone change of fluorosis (i.e., osteosclerosis in the spine and pelvis) is detectable by x-ray. Relying on x-rays, therefore, to diagnosis skeletal fluorosis will invariably fail to protect those individuals who are suffering from the pre-skeletal phase of the disease. Moreover, some individuals with clinical skeletal fluorosis will not develop an increase in bone density, let alone osteosclerosis, of the spine. Thus, relying on unusual increases in spinal bone density will under-detect the rate of skeletal fluoride poisoning in a population.

Factors which increase the risk for skeletal fluorosis
The risk for developing skeletal fluorosis, and the course the disease will take, is not solely dependent on the dose of fluoride ingested. Indeed, people exposed to similar doses of fluoride may experience markedly different effects. While the wide range in individual response to fluoride is not yet fully understood, the following are some of the factors that are believed to play a role.

Fluoride Magnifies Impact of Repetitive Stress on Joints
Research has repeatedly found that fluoride's effect on the skeleton is most pronounced in the bones and joints that undergo the greatest strain. Indeed, both the symptoms of fluorosis (i.e., joint pain and stiffness) as well as the radiological findings (e.g., exostoses, interosseuous membrane calcification) have been found to occur earliest, and most severely, in the joints
