M11.179
Familial chondrocalcinosis, unspecified ankle and foot
Clinical Classification Guidelines
Medical Intelligence & Overview
ICD-10 code M11.179 refers to a condition called familial chondrocalcinosis affecting the ankle and foot. Chondrocalcinosis, also known as calcium pyrophosphate deposition disease (CPPD), is characterized by the abnormal accumulation of calcium crystals in the cartilage. When this condition runs in families, it indicates a genetic predisposition. This condition can lead to joint pain, swelling, and reduced mobility, especially in the ankles and feet. Recognizing familial patterns can help in early diagnosis and management of symptoms.
Causes & Symptoms
Clinical Causes: Genetic predisposition to calcium crystal formation Inherited metabolic abnormalities affecting cartilage health Family history of similar joint conditions Age-related changes, especially in older adults, can exacerbate crystal deposition
Key Symptoms: Joint pain in the ankles and feet, often presenting suddenly or gradually worsening over time Swelling and tenderness in affected joints Stiffness, particularly after periods of inactivity Reduced range of motion in the joints Possible warmth and redness around the affected area Recurring episodes that may be mistaken for gout or arthritis
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a combination of clinical examination, patient history, and imaging studies. X-rays can reveal calcium deposits in the cartilage of affected joints. Synovial fluid analysis obtained via joint aspiration can detect calcium pyrophosphate crystals directly, confirming the diagnosis. Laboratory tests may also be performed to assess metabolic factors contributing to crystal formation. Given the familial nature, a detailed family history can support the diagnosis of hereditary chondrocalcinosis.
Treatment Protocols: Treatment aims to manage symptoms and improve joint function. It may include:
