Abstract

BACKGROUND: Now, total hip arthroplasty (THA) is one of the effective methods for the treatment of severe hip osteoarthritis due to fluorosis.

OBJECTIVE: To investigate the strategies and efficacy of THA for the treatment of severe hip osteoarthritis due to fluorosis.

METHODS: A total of five cases with severe hip osteoarthritis due to fluorosis were treated with THA using biological prosthesis.

RESULTS AND CONCLUSION: All incisions were healed in one stage. Position of the prosthesis was good confirmed by X-rays observation at 1 week after operation. All the cases were followed-up for averagely 13.8 months. Loosening and sinking of the prosthesis were not found during the follow-up. The average Harris scores were 83.6 and 87.8 points at postoperative 3 and 6 months respectively, which was improved as compared with preoperative score (38.4 points). Heterotopic ossification occurred in two cases, one was Brooker degree I and another was degree II. THA is an effective method to treat severe hip osteoarthritis due to fluorosis, which can significantly improve joint function and has few complications. Heterotopic ossification should be prevented after the operation.

    As shown in Table 1, a limited number of participants from both Bartlett and Cameron showed some degree of roentgenographic bone change but, in general, these changes were minimal. There was a larger number with no observable change in the ten-year interval, a fact disregarded or unreported in most fluoride

  • Medical aspects of excessive fluoride in a water supply

    A 10-year study of 116 persons in Bartlett and 121 in Cameron, Tex., was conducted to determine if prolonged exposure to fluoride in the water supply of Bartlett had produced detectable physiological effects. Bartlett's water contained about 8 p.p.m. F until 1952, when an experimental defluoridation unit was installed, reducing the

    In a 68-year-old man with a painful syndrome of the lower extremities which began at the age of 64 years, workup revealed a generalized osteopathy with sclerosis of the axial skeleton and osteopenia at the extremities associated with pathologic fractures. The occupational history showed exposure to several synthetics such as

    (1) Fluoride concentrations were determined for autopsy samples of rib, sacrum, ilium, vertebra, adhering soft tissue, and rib marrow from a patient suffering from rheumatoid (ankylosing) spondylitis of 10 years’ duration. The fluoride concentrations were not increased above normal levels. In this case, the increased bone density seen in this

    Azole therapy is widely utilized in hematopoietic stem cell transplant (HCT) recipients for the treatment of aspergillus. Complications of voriconazole treatment related to its elevated fluoride content have been described in adults, including reports of symptomatic skeletal fluorosis. We review fluoride levels, clinical, and laboratory data in five pediatric HCT recipients

  • 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.

  • 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

  • Fluoride & Osteopetrosis

    One of the most common radiological findings in skeletal fluorosis is osteosclerosis - a hardening of bones with a blurring of the trabecular structure. In advanced cases, the osteosclerotic form of fluorosis may closely resemble the appearance of osteopetrosis, a "marble bone" disease in which the bones are dense, but fragile and prone to fracture.
