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.

  • 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

  • Bone and joint pathology in fluoride-exposed workers

    Clinical and radiological investigations were performed for 2,258 aluminum workers exposed to fluoride for an average of 17.6 yr (standard deviation = 7.6). Changes in bone and joints were presented in detail in three groups: (1) exposed up to 5 yr (135 cases), (2) exposed from 6-32 yr (1,463 cases),

  • Skeletal fluorosis mimicking seronegative arthritis

    Fluorosis is endemic in certain parts of the world, especially the Asian subcontinent (1). We report an unusual presentation of fluorosis mimicking seronegative spondyloarthritis. Although fluorosis is known to cause irritable bowel syndrome-like disorder and joint pain, this could be wrongly diagnosed as a case of seronegative arthritis. Case report A 35-year-old

  • Radiological criteria of industrial fluorosis

    The bone radiographs of 43 potroom workers in an aluminium factory, on whom the diagnosis of industrial fluorosis had been confirmed by bone biopsy, are compared with radiographs from 18 control subjects. A higher frequency of ossification of ligament, tendon, and muscle attachments is observed among the fluoride exposed subjects.

  • 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.

  • "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.

  • 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.

  • Fluoride & Osteomalacia

    One of fluoride's most well-defined effects on bone tissue is it's ability to increase the osteoid content of bone. Osteoid is unmineralized bone tissue. When bones have too much of it, they become soft and prone to fracture -- a condition known as osteomalacia. As shown below, fluoride has repeatedly been

  • Fluoride & DISH (Diffuse Idiopathic Skeletal Hyperostosis)

    Among individuals with skeletal fluorosis, the fluoride-induced changes to the spine, and the accompanying symptoms, can bear a close resemblance to DISH (Forestier's Disease). Some authors report that skeletal fluorosis can so closely resemble that DISH that the only way to distinguish the two would be to conduct an invasive bone biopsy. No studies have ever been conducted to determine what role, if any, fluoride plays in the development of DISH.
