Arthrography for rheumatic disease. When, why, and for whom.

Area of Science:

• Rheumatology
• Diagnostic Imaging
• Orthopedics

Background:

• Septic arthritis is a critical diagnosis requiring prompt identification.
• Monoarticular complaints necessitate thorough evaluation, especially with normal initial radiographic findings.
• Patients with established arthritis may experience pain exacerbations due to disease progression or complications.

Purpose of the Study:

• To outline the key rheumatologic indications for aspiration/arthrogram procedures.
• To highlight the diagnostic utility of arthrography in specific clinical scenarios.
• To detail the role of contrast studies in managing patients with known arthritis.

Main Methods:

• Review of clinical indications for joint aspiration and arthrography.
• Description of the diagnostic process for septic joints.
• Explanation of arthrographic evaluation for monoarticular complaints with normal radiographs.
• Discussion of contrast study applications in patients with known arthritis.

Main Results:

• Aspiration/arthrogram is primarily indicated for septic joint diagnosis.
• It is also valuable for evaluating monoarticular complaints when plain radiographs are normal.
• In patients with known arthritis, it assesses cartilage damage, identifies pain-exacerbating complications, and evaluates soft tissue masses.

Conclusions:

• Aspiration/arthrogram is a versatile diagnostic tool in rheumatology.
• It plays a vital role in differentiating septic arthritis and evaluating unclear joint pain.
• Its application extends to comprehensive management of known arthritic conditions.
