Abstract
We examined four patients with fluorosis, presenting with compressive myelopathy, by MRI, using spin-echo and fast low-angle shot sequences. Cord compression due to ossification of the posterior longitudinal ligament (PLL) and ligamentum flavum (LF) was demonstrated in one and ossification of only the LF in one. Marrow signal was observed in the PLL and LF in all the patients on all pulse sequences. In patients with compressive myelopathy secondary to ossification of PLL and/or LF, fluorosis should be considered as a possible cause, especially in endemic regions.

Ossification of the ligamentum flavum as a result of fluorosis causing myelopathy: report of two cases
OBJECTIVE AND IMPORTANCE: Ossification of the ligamentum flavum (OLF) is increasingly being recognized as a cause of myeloradiculopathy. However, the cause of such OLF has been identified only occasionally. The purpose of this case report is to highlight one more cause of OLF causing myelopathy. CLINICAL PRESENTATION: Two middle-aged men residing

Fluorosis in Nalgonda District, Hyderabad-Deccan
Details of inviestigations of 32 cases of skeletal fluorosis with neurological manifestations are described. The results of the eighth-nerve functions are reported. The probable factors responsible for early skeletal changes in patients from Kamaguda are discussed. A case is described in which excretion of previously stored fluoride continued in the

Skeletal fluorosis causing high cervical myelopathy
Skeletal fluorosis is endemic in some parts of the world and is the result of life-long ingestion of high amounts of fluoride in drinking water. Its clinical presentation is characterized mostly by bone and dental changes with later ossification of many ligaments and interosseous membranes. We present a rare case of high cervical myelopathy

Intraosseous schwannoma of the cervical spine associated with skeletal fluorosis
Intraosseous Schwannoma of the cervical spine is very rare. Its association with skeletal fluorosis is also extremely rare. A case of successfully treated intraosseous neurofibroma of the cervical spine associated with skeletal fluorosis causing tetraparesis is reported. The clinical features, diagnostic aspects and the management is described and the literature

Fluorosis... causing paraplegia... mutilating life...
Fluorosis is thought to be rare in Pakistan but endemic in various parts of the world, especially in India and China. In Pakistan only a few cases have been reported from Thar, Sibbi and Manga Mandi, with probability of fluorosis on MRI findings, supported by high drinking waterfluoride content. Neurological

Fluoride & Spinal Stenosis
Spinal stenosis is a narrowing of the spaces in the spine that results in pressure being placed on the spinal cord and/or nerve roots. Although stenosis can develop without symptoms, it may produce numbness, tingling, pain and difficulty in walking, as well as a heavy/tired feeling in the legs. It is estimated that 250,000 to 500,000 Americans currently have symptoms of spinal stenosis. Skeletal fluorosis is one cause of stenosis.

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 & 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.

Kidney Patients Are at Increased Risk of Fluoride Poisoning
It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients
