M12.459
Intermittent hydrarthrosis, unspecified hip
Clinical Classification Guidelines
Medical Intelligence & Overview
Intermittent hydrarthrosis of the hip is a condition characterized by recurring episodes of joint swelling caused by the accumulation of excess fluid within the hip joint. Also known as fluctuating or episodic hip joint effusion, this disorder can cause discomfort and impact mobility. The ICD-10 code M12.459 specifically identifies cases where the hydrarthrosis of the hip occurs intermittently without a specified underlying cause.
Causes & Symptoms
Clinical Causes: Underlying joint diseases such as osteoarthritis or rheumatoid arthritis Infections affecting the joint, including bacterial or viral infections Trauma or injury to the hip joint leading to fluid accumulation Overuse or repetitive stress on the joint Inflammatory conditions like bursitis or synovitis Gout or pseudogout involving crystal deposits in the joint Degenerative changes associated with aging Idiopathic causes, where no specific reason can be identified
Key Symptoms: Intermittent swelling and puffiness around the hip joint Pain or tenderness during episodes of swelling Limited range of motion or stiffness in the hip Discomfort that worsens with activity or prolonged movement A feeling of instability or weakness in the hip Warmth or redness around the joint during acute episodes
Diagnostic & Treatment
Diagnosis Path: Diagnosis of intermittent hydrarthrosis involves a combination of clinical evaluation and diagnostic tests. Healthcare professionals typically perform a physical exam to assess swelling, tenderness, and mobility. To confirm the presence of excess fluid and evaluate its characteristics, procedures such as joint aspiration (arthrocentesis) may be performed, where fluid is drawn from the joint for analysis. Imaging studies like X-rays, ultrasound, or MRI can help identify joint abnormalities, signs of arthritis, or other underlying conditions. Blood tests might be utilized to detect signs of infection or autoimmune disorders related to joint inflammation.
Treatment Protocols: Treatment options focus on relieving symptoms and addressing any underlying causes. Common approaches include:
