M11.171
Familial chondrocalcinosis, right ankle and foot
Clinical Classification Guidelines
Medical Intelligence & Overview
Familial chondrocalcinosis, also known as calcium pyrophosphate dihydrate (CPPD) crystal deposition disease, is a hereditary condition that leads to the accumulation of calcium crystals in the cartilage of joints. When this occurs specifically in the right ankle and foot, it can cause joint pain, swelling, and stiffness. This condition is inherited, meaning it runs in families, and often affects the elderly but can appear at various ages depending on the genetic factors involved.
Causes & Symptoms
Clinical Causes: Genetic predisposition passed down through families Accumulation of calcium pyrophosphate dihydrate crystals in cartilage Age-related changes in joint cartilage that facilitate crystal deposition Possible metabolic abnormalities affecting calcium and phosphate balance
Key Symptoms: Joint pain, especially during movement or activity Swelling and warmth around the affected joints Stiffness, making it difficult to move the ankle and foot Possible redness of the skin over the joint Intermittent flare-ups with sudden increases in pain and swelling Limited range of motion in the affected joints
Diagnostic & Treatment
Diagnosis Path: Diagnosing familial chondrocalcinosis involves a combination of clinical evaluation and laboratory tests. A healthcare provider will review medical history and family history, perform physical examinations, and may recommend imaging studies such as X-rays that can reveal calcification in the cartilage of the affected joints. Synovial fluid analysis obtained via joint aspiration can identify calcium pyrophosphate crystals, providing definitive diagnosis.
Treatment Protocols: While there is no cure for familial chondrocalcinosis, management focuses on relieving symptoms and preventing joint damage. Treatment options may include: - Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation - Colchicine to prevent flare-ups - Corticosteroid injections for localized joint inflammation - Physical therapy to improve joint flexibility and strength - Lifestyle modifications such as weight management and activity adjustments - Monitoring and managing any underlying metabolic disorders that might contribute to crystal formation Effective management requires regular medical follow-up to adjust treatments based on symptom severity and progression.
