M02.9
Reactive arthropathy, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
Reactive arthropathy, also known as reactive arthritis, is a condition where the joints become inflamed as a response to an infection elsewhere in the body. Although the exact cause isn't always clear, it typically develops after certain infections, leading to joint pain and swelling. The term 'unspecified' indicates that this diagnosis does not specify the exact joint or cause but highlights the presence of joint inflammation linked to an infection.
Causes & Symptoms
Clinical Causes: Infections caused by bacteria such as Chlamydia trachomatis, Salmonella, Shigella, Yersinia, and Campylobacter Recent gastrointestinal infections Recent urinary tract infections Genetic predispositions, such as the presence of the HLA-B27 gene Other infections leading to immune system reactions that affect the joints
Key Symptoms: Joint pain, often affecting the knees, ankles, and feet Swelling and tenderness in affected joints Limited range of motion in affected joints Inflammation of the tendons and ligaments around the joints Fatigue and general malaise Possible skin and eye symptoms, such as conjunctivitis or skin rashes Fever in some cases
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of a patient's medical history, physical examination, and laboratory tests. Physicians may look for recent infections and check for joint swelling, warmth, and tenderness. Blood tests can detect signs of inflammation and identify specific infections or genetic markers like HLA-B27. Joint aspiration (removing fluid from the joint) and imaging studies, such as X-rays, can help rule out other conditions and confirm inflammation typical of reactive arthropathy.
Treatment Protocols: Treatment focuses on relieving symptoms and managing inflammation. Approaches may include:
