ICD-10: M11.09

Hydroxyapatite deposition disease, classified under ICD-10 code M11.09, is a condition characterized by the abnormal accumulation of hydroxyapatite crystals in various tissues, leading to inflammation and pain. This condition is often associated with calcific tendinitis and can affect multiple sites in the body, particularly in the joints and soft tissues.

Clinical Description

Definition

Hydroxyapatite deposition disease is a type of crystal-induced arthropathy, where hydroxyapatite crystals, which are calcium phosphate minerals, deposit in the synovial tissues, tendons, and ligaments. This deposition can trigger an inflammatory response, resulting in pain, swelling, and reduced mobility in the affected areas.

Symptoms

Patients with hydroxyapatite deposition disease may experience:
- Joint Pain: Often severe and can be acute or chronic, typically affecting the shoulder, hip, or knee joints.
- Swelling and Inflammation: Localized swelling around the affected joints or tendons.
- Limited Range of Motion: Due to pain and inflammation, patients may find it difficult to move the affected joint.
- Tenderness: The affected area may be sensitive to touch.

Etiology

The exact cause of hydroxyapatite deposition disease is not fully understood, but it is believed to be related to:
- Metabolic Disorders: Conditions that affect calcium and phosphate metabolism may predispose individuals to crystal formation.
- Trauma or Overuse: Repetitive stress or injury to a joint can lead to the deposition of hydroxyapatite crystals.
- Age: The condition is more common in older adults, possibly due to degenerative changes in the joints.

Diagnosis

Clinical Evaluation

Diagnosis typically involves a thorough clinical history and physical examination. Key aspects include:
- Symptom Assessment: Evaluating the nature, duration, and location of pain.
- Physical Examination: Checking for swelling, tenderness, and range of motion in the affected joints.

Imaging Studies

• X-rays: May reveal calcifications in the soft tissues or around the joints.
• Ultrasound: Useful for detecting hydroxyapatite deposits in tendons and soft tissues.
• MRI: Can provide detailed images of the affected areas, helping to assess the extent of inflammation and damage.

Laboratory Tests

While there are no specific blood tests for hydroxyapatite deposition disease, tests may be conducted to rule out other conditions, such as gout or rheumatoid arthritis.

Treatment

Conservative Management

• Rest and Activity Modification: Reducing activities that exacerbate symptoms.
• Physical Therapy: To improve range of motion and strengthen surrounding muscles.
• Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to manage pain and inflammation.

Invasive Procedures

In cases where conservative treatment fails, more invasive options may be considered:
- Corticosteroid Injections: To reduce inflammation directly in the affected area.
- Surgery: In severe cases, surgical intervention may be necessary to remove large deposits or repair damaged tissues.
