ICD-10: M11.15

Familial chondrocalcinosis, also known as familial calcium pyrophosphate deposition disease (CPPD), is a hereditary condition characterized by the accumulation of calcium pyrophosphate crystals in the cartilage and synovial fluid of joints. This condition can lead to joint pain, swelling, and inflammation, particularly affecting the hips, knees, and wrists.

Clinical Description

Pathophysiology

Familial chondrocalcinosis is primarily caused by genetic mutations that affect the metabolism of pyrophosphate, leading to its accumulation in the cartilage. The excess pyrophosphate promotes the formation of calcium pyrophosphate crystals, which can deposit in the cartilage and synovial fluid, resulting in inflammation and joint damage. This condition is often inherited in an autosomal dominant pattern, meaning that only one copy of the mutated gene from an affected parent can cause the disease in offspring.

Symptoms

Patients with familial chondrocalcinosis may experience a range of symptoms, including:
- Joint Pain: Often severe and can be episodic or chronic.
- Swelling: Affected joints may appear swollen due to inflammation.
- Stiffness: Particularly after periods of inactivity or in the morning.
- Limited Range of Motion: Affected joints may have reduced mobility.

The hip joint is commonly affected, leading to significant discomfort and functional impairment. Attacks of acute arthritis can mimic gout, making differential diagnosis important.

Diagnosis

Diagnosis typically involves:
- Clinical Evaluation: A thorough history and physical examination to assess symptoms and joint involvement.
- Imaging Studies: X-rays may reveal calcifications in the cartilage, particularly in the hip joint. Advanced imaging techniques like MRI can provide more detailed views of joint structures.
- Synovial Fluid Analysis: Aspiration of joint fluid can help identify the presence of calcium pyrophosphate crystals under polarized light microscopy.

Treatment

Management of 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 joint.
- Physical Therapy: To improve joint function and mobility.
- Surgical Intervention: In severe cases, procedures such as arthroscopy may be necessary to remove calcified deposits.

ICD-10 Code M11.15

The ICD-10 code M11.15 specifically designates "Familial chondrocalcinosis, hip." This classification is part of the broader category of chondrocalcinosis, which encompasses various forms of calcium pyrophosphate deposition diseases.
