Scapholunate advanced collapse and scaphoid nonunion advanced collapse: MDCT arthrography features

Area of Science:

• Radiology
• Orthopedic Imaging
• Musculoskeletal Imaging

Background:

• Scapholunate advanced collapse (SLAC) and scaphoid nonunion advanced collapse (SNAC) wrist represent common patterns of wrist arthritis.
• Accurate diagnosis is crucial for effective management and treatment planning.

Purpose of the Study:

• To detail the imaging characteristics of SLAC and SNAC wrist on multi-detector computed tomography (MDCT) arthrography.
• To correlate imaging findings with the stages of disease progression.

Main Methods:

• MDCT arthrography was performed on patients with suspected SLAC or SNAC wrist.
• Imaging features, including joint space narrowing, erosions, and carpal alignment, were analyzed.
• Correlation with clinical presentation and surgical findings was assessed.

Main Results:

• MDCT arthrography demonstrated characteristic findings for both SLAC and SNAC wrist.
• The imaging modality allowed for detailed assessment of cartilage degeneration, subchondral bone changes, and ligamentous integrity.
• Specific patterns were identified corresponding to different stages of disease.

Conclusions:

• MDCT arthrography is a valuable tool for diagnosing and classifying SLAC and SNAC wrist.
• It provides comprehensive visualization of the spectrum of pathological changes.
• The findings directly influence treatment decisions and patient management strategies.
