Abstract
Acute pain in the lower extremity, which has previously been attributed to synovitis or fasciitis, develops in about 15 percent of osteoporotic patients treated with sodium fluoride. This report describes 11 osteoporotic women in whom this syndrome developed while they were being treated with sodium fluoride (mean dose 78 mg per day; range, 60 to 90). [99mTc]Hydroxymethylene diphosphonate scintiscanning showed an increased number of foci of abnormal uptake in the lower extremities (p less than 0.05), when compared with results of scintiscanning in 12 nonsymptomatic osteoporotic women treated with sodium fluoride and 12 osteoporotic women treated with oral calcium carbonate only. The increased uptake was not restricted to the areas of pain. Roentgenography revealed stress microfractures in five of the 11 symptomatic patients. It is concluded that the acute lower extremity pain syndrome during fluoride therapy usually results from intense regional bone remodeling, which may be complicated by stress microfractures.

Three-year effectiveness of intravenous pamidronate versus pamidronate plus slow-release sodium fluoride for postmenopausal osteoporosis
All currently available and approved therapies for osteoporosis inhibit bone resorption. But, despite their great value, antiresorptive agents are generally not associated with dramatic increases in bone mass. In light of these data, the aim of our prospective, placebo-controlled, randomized clinical trial, with a 3-year follow up, was to examine

Fluorosis with report of an advanced case.
It is quite possible that endemic centres [of skeletal fluorosis] exist but that the cause of the disabling spondylitis or other joint affections has not been determined, and a diagnosis of chronic arthritis has resulted. Few cases in Canada or the United States will be found to be as dramatic

Community Water Fluoridation and Rate of Pediatric Fractures
Background: The effect of community water fluoridation on bone fragility and fracture has been inconclusive in the literature. The null hypothesis of this study was that no association was observed between water fluoride level and risk of fracture in children. Methods: Community fluoridation data were obtained from the Centers for Disease Control and

Fluoride and fractures: an ecological fallacy.
Fluoridation of public water to prevent dental caries has been advocated for more than a half century in the UK and USA, and the benefits of optimum fluoridation for oral health have been affirmed by the US Public Health Service.1 In addition to the beneficial effects on teeth, fluoride ingestion

Summary of workshop on drinking water fluoride influence on hip fracture on bone health. (National Institutes of Health, 10 April, 1991)
An ecologic study [22] compared fracture rates in 216 counties with natural fluoride levels greater than 0.7 ppm with rates in 95 counties with naturally low fluoride (less than 0.4 PPM) in the drinking water (Dose Ecology Study). Hip fracture ratios used as a denominator the hip fracture rates

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.

Fluoride Reduces Bone Strength in Animals
Most animal studies investigating how fluoride effects bone strength have found either a detrimental effect, or no effect. Few animal studies have found a beneficial effect. In fact, one of the few studies that found a beneficial effect was unable to be repeated by the same authors in a later

Fluoride Content of Bone Impairs Bone Quality
Water Fluoridation Increases the Fluoride Content of Bone "Fluoride analyses of the cadaver material from Kuopio revealed that fluoridation of drinking water increases the fluoride concentration in bone. In some individual cases the amount of fluoride in trabecular bone may rise to relatively high levels, notably in patients with impaired renal

Fluoride & Spontaneous Hip Fractures in Osteoporosis Patients
Due to its ability to increase vertebral bone mass, fluoride has been used as an experimental treatment for osteoporosis (doses > 20 mg/day). Fluoride treatment, however, proved far more harmful than beneficial. Not only was fluoride therapy shown to increase fracture rates among the treated patients, it was also found to

The Relationship Between Fluoride, Bone Density, and Bone Strength
Although fluoride has generally been found to reduce the bone density of cortical bone, it is well documented that fluoride can increase the density of trabecular bone (aka cancellous bone). Trabecular bone is the primary bone of the spine, whereas cortical bone is the primary bone of the legs and arms. While increases in
