What is the optimal imaging plane for visualizing a triangular fibrocartilage complex (TFCC) tear?

Axial wrist
Sagittal wrist
Coronal wrist
Transverse wrist

The correct answer is: Coronal wrist

The optimal imaging plane for visualizing a triangular fibrocartilage complex (TFCC) tear is the coronal wrist. This imaging orientation allows for the most comprehensive evaluation of the TFCC, as it enables clear visualization of the structure in its entirety, including both the dorsal and volar aspects. The coronal plane aligns well with the anatomical positioning of the TFCC, which is located on the ulnar side of the wrist, connecting the ulnar head to the distal radius. By utilizing the coronal plane, radiologists and clinicians can better assess the integrity of the TFCC and identify any tears or degenerative changes. This plane also facilitates the assessment of the surrounding anatomical structures, which can be crucial for accurate diagnosis and treatment planning. While the axial and sagittal planes may provide some information about the wrist's anatomy, they are not as effective for a detailed evaluation of the TFCC specifically. Therefore, the coronal wrist is indeed the optimal choice for this purpose.
