ICD-10: M11.07

Hydroxyapatite deposition disease, classified under ICD-10 code M11.07, is a condition characterized by the abnormal accumulation of hydroxyapatite crystals in the soft tissues of the body, particularly affecting the joints. This condition can lead to inflammation, pain, and functional impairment, especially in the ankle and foot regions.

Clinical Description

Definition

Hydroxyapatite deposition disease, also known as calcific tendinitis or calcific bursitis, occurs when hydroxyapatite crystals, which are a form of calcium phosphate, deposit in the soft tissues surrounding joints. This deposition can trigger an inflammatory response, resulting in pain and swelling in the affected areas.

Symptoms

Patients with hydroxyapatite deposition disease may experience a range of symptoms, including:
- Localized Pain: Often severe and can be exacerbated by movement or pressure on the affected joint.
- Swelling: Inflammation in the ankle and foot may lead to noticeable swelling.
- Limited Range of Motion: Pain and swelling can restrict movement, making it difficult to perform daily activities.
- Tenderness: The affected area may be sensitive to touch.

Affected Areas

While hydroxyapatite deposition disease can occur in various joints, the ankle and foot are common sites due to the mechanical stress they endure. The condition can affect tendons, ligaments, and bursae in these regions, leading to significant discomfort.

Diagnosis

Clinical Evaluation

Diagnosis typically involves a thorough clinical evaluation, including:
- Patient History: Understanding the onset, duration, and nature of symptoms.
- Physical Examination: Assessing tenderness, swelling, and range of motion in the ankle and foot.

Imaging Studies

Imaging techniques are crucial for confirming the diagnosis:
- X-rays: Can reveal calcifications in the soft tissues around the joint.
- Ultrasound: Useful for visualizing the extent of hydroxyapatite deposits and assessing inflammation.
- MRI: May be employed to evaluate soft tissue involvement and rule out other conditions.

Treatment

Conservative Management

Initial treatment often focuses on conservative measures:
- Rest: Avoiding activities that exacerbate symptoms.
