ICD-10: M85.13

Skeletal fluorosis is a bone disease caused by excessive accumulation of fluoride in the bones, leading to changes in bone structure and density. The ICD-10-CM code M85.13 specifically refers to skeletal fluorosis localized in the forearm. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of Skeletal Fluorosis

Etiology

Skeletal fluorosis occurs primarily due to prolonged exposure to high levels of fluoride, which can be found in drinking water, certain industrial environments, and some dental products. The condition is more prevalent in areas where fluoride is naturally high in groundwater or where industrial emissions contribute to environmental fluoride levels.

Pathophysiology

Fluoride is incorporated into the bone matrix, replacing hydroxyl groups in hydroxyapatite, which can lead to increased bone density but also to structural abnormalities. Over time, excessive fluoride can cause:
- Bone deformities: Changes in bone architecture can lead to stiffness and pain.
- Joint issues: Fluoride accumulation can affect joints, leading to arthritis-like symptoms.
- Calcification of ligaments: This can further contribute to mobility issues.

Symptoms

Patients with skeletal fluorosis may present with a variety of symptoms, including:
- Pain and stiffness: Particularly in the forearm and other affected areas.
- Limited mobility: Due to joint and bone changes.
- Bone deformities: Visible changes in bone structure may occur over time.
- Increased fracture risk: Although bones may be denser, they can also become brittle.

Diagnosis

Diagnosis of skeletal fluorosis typically involves:
- Clinical evaluation: Assessment of symptoms and medical history, including exposure to fluoride.
- Radiographic imaging: X-rays may reveal characteristic changes in bone density and structure.
- Laboratory tests: Measurement of fluoride levels in urine or bone may be conducted to confirm excessive exposure.

Treatment

Management of skeletal fluorosis focuses on reducing fluoride exposure and alleviating symptoms. Treatment options may include:
- Discontinuation of fluoride sources: Identifying and eliminating sources of fluoride exposure is crucial.
- Pain management: Non-steroidal anti-inflammatory drugs (NSAIDs) may be used to relieve pain and inflammation.
- Physical therapy: To improve mobility and strengthen surrounding muscles.
