M11.149
Familial chondrocalcinosis, unspecified hand
Clinical Classification Guidelines
Medical Intelligence & Overview
Familial chondrocalcinosis, also known as calcium pyrophosphate dihydrate (CPPD) crystal deposition disease, is a condition characterized by abnormal calcium crystal deposits in the cartilage of joints. When it affects the hands, it can lead to joint pain, stiffness, and swelling. The code M11.149 specifies a familial form of this disease affecting the hand, indicating a hereditary tendency to develop calcium crystal deposits in this specific area.
Causes & Symptoms
Clinical Causes: Genetic predisposition: A family history of chondrocalcinosis increases risk. Inherited metabolic disorders that influence calcium and phosphate balance. Aging: The likelihood of crystal deposits increases with age, often seen in genetically predisposed individuals. Other contributing factors include joint trauma or previous joint injuries.
Key Symptoms: Joint pain, often described as aching or throbbing, especially during movement. Swelling and inflammation around the affected joint. Stiffness, making movement difficult, particularly in the morning or after periods of inactivity. Crepitus: A grating sensation or sound when the joint is moved. Possible warmth over the affected joint. Deformity in advanced cases, with joint swelling and misalignment.
Diagnostic & Treatment
Diagnosis Path: X-rays to identify calcium deposits within the cartilage of the hand joints. Joint aspiration to analyze synovial fluid for calcium pyrophosphate crystals. Laboratory tests to rule out other causes of joint pain, such as gout or osteoarthritis. Genetic testing if a familial pattern is suspected to understand hereditary factors.
Treatment Protocols: Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation. Colchicine, which can help prevent crystal formation and reduce flare-ups. Corticosteroid injections directly into the affected joint for significant inflammation. Physical therapy and exercises to maintain joint mobility and strength. Lifestyle modifications, such as weight management and avoiding joint stress. Monitoring and managing underlying metabolic conditions that may contribute to crystal deposits.
