Abstract

BACKGROUND: Knee osteoarthritis caused by endemic skeletal fluorosis is a complex and chronic systemic disease,which can cause the damage of surrounding bone and sclerotin of knee joint.

OBJECTIVE: To investigate the effect of total knee arthroplasty (TKA) in the treatment of knee osteoarthritis caused by endemic skeletal fluorosis.

METHODS: Nine patients suffered from knee osteoarthritis caused by skeletal fluorosis that diagnosed by local epidemiology,dental fluorosis,clinical and imaging from March 2010 to October 2011 and all the patients were treated with bilateral TKA. The clinical efficacy was evaluated according to the knee scoring system of United States Hospital for Special Surgery before arthroplasty and final follow-up after arthroplasty.

RESULTS AND CONCLUSION: Score results showed that 5 knees were excellent, 3 knees were good and 1 knee was fair after knee arthroplasty. All patients have been improved in pain, function and range of motion. TKA is an effective method for the treatment of knee osteoarthritis caused by skeletal fluorosis.

  • 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

    Article w/o Photos (see pdf attached) Patient SK, a 40-yr-old female, resident of Bhagalpur village in Bihar, India, was operated for gallstones 3 years previously. On pre-operative checkup, mild renal dysfunction was detected. She was asymptomatic for renal disease with serum creatinine of 159 mmol/l (1.8mg/dl), bland urinary sediment and small echo-genic kidneys on ultrasound. She was

  • Industrial fluorosis [Franke et al.]

    This is a review of findings on workers in an aluminum plant with industrial fluorosis. Early signs of the disease are nocturnal back pains and restriction of the rotation of the trunk. Stage I of the disease usually occurs after 10 years, stage II after 15 years and stage III

  • Elevated fluoride levels and periostitis in pediatric hematopoietic stem cell transplant recipients receiving long-term voriconazole

    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

  • Screening vs. individual detection of industrial fluorosis: a decision analysis model

    In preventive medicine and occupational health, decision-makers face uncertainty, divergent opinions, and varying needs. In the Swiss aluminum industry, screening for industrial fluorosis illustrates how decision analysis and cost-effectiveness analysis can provide rational and explicit models of decision-making in such contexts. Data on fluoride-exposed potroom workers are used to compare

  • 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 Reduces Bone Strength Prior to Onset of Skeletal Fluorosis

    The majority of animal studies investigating fluoride's impact on bone strength have found that fluoride has either no effect, or a detrimental effect, on bone strength. Importantly, several of the animal studies that have found fluoride reductes bone strength have reported that this reduction in strength occurs before signs of skeletal fluorosis

  • Similarities between Skeletal Fluorosis and Renal Osteodystrophy

    It is quite possible, and indeed likely, that some kidney patients diagnosed with renal osteodystrophy are either suffering from skeletal fluorosis or their condition is being complicated/exacerbated by fluoride exposure.
