Diagnostic Criteria for M13.13

Clinical Evaluation

1. Patient History: A thorough medical history is essential. The clinician should inquire about the onset, duration, and characteristics of the joint pain, including any associated symptoms such as swelling, stiffness, or redness. Previous joint injuries or family history of arthritis may also be relevant.

2. Physical Examination: The clinician should perform a detailed physical examination of the wrist joint. This includes assessing:
   - Range of Motion: Evaluating both active and passive movements to determine any limitations.
   - Swelling and Tenderness: Noting any signs of inflammation, such as swelling, warmth, or tenderness upon palpation.
   - Deformities: Checking for any visible deformities or abnormalities in the wrist structure.

Diagnostic Imaging

1. X-rays: Radiographic imaging is often the first step in evaluating joint conditions. X-rays can help identify:
   - Joint space narrowing
   - Bone erosions
   - Osteophyte formation
   - Other degenerative changes

2. MRI or Ultrasound: In some cases, advanced imaging techniques like MRI or ultrasound may be utilized to assess soft tissue structures, synovial inflammation, or to rule out other conditions such as tendon injuries or cysts.

Laboratory Tests

1. Blood Tests: While not always necessary, certain blood tests can help rule out specific types of arthritis:
   - Rheumatoid Factor (RF): To check for rheumatoid arthritis.
   - Anti-Citrullinated Protein Antibodies (ACPA): Another marker for rheumatoid arthritis.
   - Complete Blood Count (CBC): To assess for signs of infection or inflammation.
   - Erythrocyte Sedimentation Rate (ESR) or C-reactive protein (CRP): To evaluate the level of inflammation in the body.

2. Joint Aspiration: If there is significant swelling, aspiration of the joint fluid may be performed. Analyzing the synovial fluid can help determine the presence of infection, crystals (indicative of gout or pseudogout), or other inflammatory markers.

Differential Diagnosis

It is crucial to differentiate monoarthritis from other conditions that may present similarly. Conditions to consider include:
- Gout: Characterized by sudden, severe pain and swelling, often in the big toe but can affect the wrist.
