M02.359
Reiter's disease, unspecified hip
Clinical Classification Guidelines
Medical Intelligence & Overview
Reiter's disease, also known as reactive arthritis, is an inflammatory condition that primarily affects the joints, eyes, and urinary tract. When it involves the hip, it can cause significant pain and mobility issues. This condition typically develops following an infection elsewhere in the body, often related to gastrointestinal or urogenital infections. The code M02.359 specifies cases where Reiter's disease impacts the unspecified hip, reflecting the diverse ways this disease can manifest. Recognizing the symptoms and understanding the potential causes are essential steps toward managing this condition effectively.
Causes & Symptoms
Clinical Causes: Recent bacterial infections, especially from gastrointestinal pathogens like Salmonella, Shigella, Yersinia, or Campylobacter. Urogenital infections caused by organisms such as Chlamydia trachomatis. Genetic predisposition, including the presence of the HLA-B27 gene. Environmental factors and immune system responses triggering inflammation after infection.
Key Symptoms: Joint pain and swelling, especially in the hips, knees, and ankles. Inflammation of the eyes (conjunctivitis or uveitis). Pain or burning sensation during urination. Lower back pain or buttock discomfort. Skin rashes or lesions, including keratoderma blennorrhagicum or circinate balanitis. General fatigue and malaise.
Diagnostic & Treatment
Diagnosis Path: Diagnosis primarily relies on clinical evaluation, patient history, and laboratory tests. Physicians may look for recent infections, joint symptoms, and signs of inflammation. Blood tests might reveal elevated inflammatory markers like ESR and CRP, and HLA-B27 testing can support the diagnosis. Joint fluid analysis may be performed to rule out other causes of arthritis. Imaging studies such as X-rays or MRI scans can help assess joint involvement and rule out structural damage.
Treatment Protocols: Nonsteroidal anti-inflammatory drugs (NSAIDs) to control pain and swelling. Corticosteroids for more severe inflammation, administered orally or via injection. Antibiotics if active bacterial infection is identified or suspected. Physical therapy to maintain joint function and mobility. Disease-modifying antirheumatic drugs (DMARDs) in chronic or persistent cases. Rest and joint protection strategies.
