Purpose
TFCC is a complex structure at the ulnar sided wrist joint composed of multiple components. It plays a vital role in distal radioulnar and ulnocarpal joints stability where palmar and dorsal radioulnar ligaments are regarded as the major factors [1-4]. A 3.0 T wrist MRA with a special 3D isotropic proton density-weighted fat-suppressed sequence has been used and reported to have better results [5-10, 13]. Palmer classification is widely used for TFCC injury which includes traumatic (class 1 injuries): 1A (central perforation), 1B (ulnar avulsion), 1C (distal avulsion) and 1D (radial avulsion), and atraumatic (class 2 injuries) [11]. However, there are some limitations for understanding it in detail [12]. The main objective of this study is to investigate frequency, distribution, and pattern of injuries on various components of the TFCC and associated structures using high-resolution 3.0 T MRI.
