Triangular Fibrocartilage Complex (TFCC) - Anatomy, Imaging, and Classifications with Special Focus on the CUP...

Area of Science:

• Radiology
• Orthopedics
• Anatomy

Background:

• The Triangular Fibrocartilage Complex (TFCC) has complex anatomy and requires specialized imaging.
• Existing TFCC classifications are incomplete, necessitating improved diagnostic tools.

Purpose of the Study:

• To review the anatomy and pathoanatomy of the TFCC.
• To explain and compare MRI, MR arthrography, and CT arthrography for TFCC imaging.
• To introduce and illustrate the novel CUP classification for TFCC lesions.

Main Methods:

• Review of current literature on TFCC anatomy and imaging techniques.
• Explanation of MRI, MR arthrography, and CT arthrography for TFCC lesions.
• Presentation and illustration of the CUP classification with image examples.

Main Results:

• Accurate TFCC imaging requires thin slices, high in-plane resolution, and optimized contrast.
• Gadolinium-enhanced MRI aids in visualizing repair tissue.
• MR and CT arthrography remain the reference standards for TFCC imaging.
• The CUP classification provides a comprehensive system for describing and categorizing TFCC lesions.

Conclusions:

• The TFCC comprises distinct anatomical components requiring specific imaging approaches.
• The CUP classification offers a standardized method for TFCC lesion assessment.
• Advanced imaging techniques and the CUP classification improve the understanding and diagnosis of TFCC injuries.
