Imaging of TFCC is challenging given its complex anatomy and small size. Recent advances in MR particularly in spatial and contrast resolution have now facilitated more accurate assessment of this structure. We propose to: 1.Describe basic scanning protocols and image optimization techniques. 2.Illustrate MR imaging anatomy of TFCC including common pitfalls. 3.Discuss spectrum of imaging findings in TFCC injuries and their therapeutic implications.

The triangular fibrocartilage complex (TFCC) is a complex anatomic and biomechanical structure. Injury to the TFCC is an important cause of ulnar wrist pain. It may be injured in its central portion, in its peripheral portions or at its attachments. Given its complex anatomy and small size, imaging of TFCC is inherently challenging. MR with its superior spatial and contrast resolution is now the gold standard in imaging the TFCC. The reporting radiologist needs to have a thorough understanding of normal anatomy and imaging findings...

Procedural Details A retrospective review of MR wrists done in our institution over a 3 year period was performed and illustrative cases were selected. Imaging technique, normal MR appearance, variant anatomy that mimic TFCC disease and spectrum of imaging findings in TFCC injury are discussed. Normal TFCC Anatomy TFCC is a complex of a fibrocartilaginous disk in association with several ligamentous structures. Fig. 1 TFCC stabilises the distal radioulnar joint, and transmits axial loading from carpus to the ulna. TFCC is comprised of the following...

MR is increasingly used in the evaluation of TFCC injuries. A thorough understanding of imaging technique, normal and variant anatomy and injury patterns is vital in improving diagnostic accuracy and guiding patient management.
