ICD-10: M11.18

ICD-10 code M11.18 refers to Familial chondrocalcinosis, vertebrae, a specific type of crystal arthropathy characterized by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in the cartilage and other connective tissues. This condition is part of a broader category of disorders known as chondrocalcinosis, which can lead to joint pain and inflammation.

Clinical Description

Definition

Familial chondrocalcinosis is a hereditary condition that results in the accumulation of calcium pyrophosphate crystals in the joints, particularly affecting the vertebrae in this case. This condition can lead to degenerative changes in the cartilage and may result in symptoms similar to those of osteoarthritis.

Symptoms

Patients with familial chondrocalcinosis may experience:
- Joint Pain: Often localized to the affected areas, particularly in the spine.
- Stiffness: Reduced range of motion in the affected joints.
- Swelling: Inflammation around the joints may occur, leading to visible swelling.
- Acute Attacks: Episodes of acute pain and inflammation, resembling gout attacks, can occur.

Pathophysiology

The underlying mechanism involves the abnormal metabolism of pyrophosphate, leading to its accumulation and subsequent crystal formation. These crystals can trigger inflammatory responses in the joints, resulting in pain and swelling. The condition is often inherited in an autosomal dominant pattern, meaning that a single copy of the mutated gene can cause the disorder.

Diagnosis

Clinical Evaluation

Diagnosis typically involves a combination of clinical evaluation and imaging studies:
- Medical History: A thorough history of symptoms and family history of similar conditions.
- Physical Examination: Assessment of joint tenderness, swelling, and range of motion.
- Imaging Studies: X-rays may reveal calcifications in the cartilage and other changes associated with chondrocalcinosis.

Laboratory Tests

• Joint Aspiration: Analysis of synovial fluid can help identify the presence of CPPD crystals.
• Blood Tests: While not definitive for diagnosis, they can help rule out other conditions.

Treatment

Management Strategies

Treatment for familial chondrocalcinosis focuses on alleviating symptoms and may include:
- Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): To reduce pain and inflammation.
- Corticosteroids: In cases of severe inflammation, corticosteroids may be injected into the affected joints.
- Physical Therapy: To improve joint function and mobility.
- Surgical Intervention: In severe cases, surgical options may be considered to relieve symptoms or correct joint deformities.
