M02.31
Reiter's disease, shoulder
Clinical Classification Guidelines
Medical Intelligence & Overview
Reiter's disease, also known as reactive arthritis, is an inflammatory condition that develops as a reaction to an infection elsewhere in the body. When it affects the shoulder, it can cause pain, swelling, and limited movement. Although it is less common than other joint involvements, shoulder Reiter's disease can significantly impact daily activities and quality of life. The condition is often part of a broader pattern of joint and tissue inflammation, and early recognition can help manage symptoms effectively.
Causes & Symptoms
Clinical Causes: Infection with certain bacteria such as Chlamydia trachomatis (a common sexually transmitted infection). Other bacterial infections including Salmonella, Shigella, Yersinia, and Campylobacter, often linked to foodborne illnesses. Genetic predisposition, particularly the presence of the HLA-B27 gene. Environmental factors, such as stress or trauma, may influence the development of symptoms, though they are not direct causes.
Key Symptoms: Joint pain and swelling in the shoulder, often accompanied by stiffness. Reduced range of motion, making it difficult to lift or rotate the arm. Tenderness and warmth around the shoulder joint. Possible redness and swelling of nearby tissues. Associated systemic symptoms such as fever, fatigue, and malaise. Additional signs of reactive arthritis may include inflammation in other joints (like knees or ankles), and symptoms affecting the eyes or urinary tract.
Diagnostic & Treatment
Diagnosis Path: A physical examination to assess joint swelling, tenderness, and range of motion. Blood tests to identify markers of inflammation such as elevated ESR or CRP levels. HLA-B27 genetic testing, which can support the diagnosis if positive. Synovial fluid analysis to rule out other causes of joint inflammation, such as gout or infection. Imaging studies like X-rays or MRI scans may be used to evaluate joint damage or inflammation, especially if symptoms persist.
Treatment Protocols: Nonsteroidal anti-inflammatory drugs (NSAIDs) to control pain and inflammation. Corticosteroids, either oral or injectable, for more severe symptoms. Physical therapy to maintain joint mobility and strengthen surrounding muscles. Addressing underlying infections if identified, often involving antibiotics or other targeted therapies. In chronic or severe cases, disease-modifying antirheumatic drugs (DMARDs) may be prescribed to control immune-mediated inflammation. Lifestyle modifications such as rest during flare-ups and avoiding joint stress can be beneficial.
