ICD-10: M85.169

Skeletal fluorosis is a bone disease caused by excessive accumulation of fluoride in the bones, typically due to prolonged exposure to high levels of fluoride, often from drinking water, industrial exposure, or excessive use of fluoride supplements. The condition can lead to various skeletal abnormalities and symptoms, including pain, stiffness, and changes in bone structure.

Clinical Description of Skeletal Fluorosis

Etiology

Skeletal fluorosis occurs when fluoride levels in the body exceed safe limits, leading to the deposition of fluoride in the bones. This can result from:
- Environmental exposure: High fluoride levels in drinking water, particularly in certain geographic areas.
- Occupational exposure: Workers in industries such as aluminum production, phosphate fertilizer manufacturing, and glass production may be at risk.
- Dietary sources: Excessive consumption of fluoride supplements or certain foods high in fluoride.

Pathophysiology

Fluoride affects bone metabolism by:
- Inhibiting osteoclastic activity: This leads to reduced bone resorption and can result in increased bone density.
- Stimulating osteoblastic activity: This can cause abnormal bone formation, leading to changes in bone architecture and increased brittleness.

Symptoms

Patients with skeletal fluorosis may experience:
- Joint pain and stiffness: Particularly in the lower extremities.
- Bone deformities: Changes in bone structure can lead to deformities, especially in the spine and long bones.
- Calcification of ligaments: This can contribute to reduced mobility and discomfort.

Diagnosis

The diagnosis of skeletal fluorosis is primarily clinical, supported by:
- Patient history: Assessing fluoride exposure through water, diet, and occupation.
- Radiological findings: X-rays may show characteristic changes in bone density and structure, such as increased radiopacity and bone deformities.
- Biochemical tests: Measurement of fluoride levels in urine or serum can help confirm excessive exposure.
