Abstract Objective: To explore the MRI characteristics of injuries of triangular fibrocartilage complex (TFCC), and provide imaging basis for the early diagnosis and treatment of the injuries. Figure 19 Comparison of TFCC visualization by non-arthrogram MRI (A) and MR arthrogram (B). Before injection of contrast, the prestyloid recess (block curved arrow) is not distended and the radiocarpal joint surface of TFCC cannot be well delineated. After contrast injection into the joint, the joints are well distended including the prestyoid recess (block curved arrow) and DRUJ Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu.

The imaging evaluation and interpretation of the triangular fibrocartilage complex (TFCC) is both challenging and rewarding for the radiologist and surgeon alike. The TFCC comprises a complicated group of fibrocartilaginous and ligamentous structures at the ulnar aspect of the wrist that plays an im Although MRI is highly accurate in the detection of TFCC tears, MRI cannot reliably differentiate traumatic from degenerative injuries. History of recent antecedent trauma for traumatic injuries and positive ulnar variance for degenerative injuries are helpful distinguishing features.

Abstract Introduction: The diagnostic value of clinical tests and magnetic resonance (MR) imaging for the investigation of triangular fibrocartilaginous complex (TFCC) lesions is not clear due to a lack of clinical data.

The triangular fibrocartilaginous complex is made of multiple components, of which the palmar and dorsal radioulnar ligaments play an important role in distal radioulnar joint stability. The ulnar wrist ligaments may be injured during forearm and wrist trauma. There are several aspects of triangular fibrocartilaginous complex management that are still open to

There is dorsal subluxation of the distal ulna at the sigmoid notch associated with moderate subchondral cystic changes (block long arrows) of the radius; (B) coronal proton density fat-suppressed MR image of another patient showed an ulnar-sided tear of the TFCC (solid long Ritesh Durgapersad, RT (R) ARMIT The triangular fibrocartilage complex (TFCC) is a major stabilizer of the distal radioulnar joint. An injury to the triangular fibrocartilage complex can result in chronic wrist pain. TFCC tears can be difficult to diagnose via imaging as it is an intrinsic small and thin structure with complex anatomy (1) . A dorsal-sided, partial triangular fibrocartilaginous complex (TFCC) tear was arthroscopically confirmed and sutured. The intra-articular fragments in the distal radioulnar joint were arthroscopically removed.

The triangular ligament attaches triangular fibrocartilage to the uln The triangular fibrocartilage complex (TFCC) is an example of one such structure, for which lesions may be missed unless high-resolution magnetic resonance imaging (MRI) obtained via a standard matrix with a small field of view or high-resolution imaging matrix (small spatial scale matrix elements/large matrix size) is utilized.

In 14 of the patients who underwent surgery, a diagnosis of triangular fibrocartilage (TFC) tear was made at MR imaging; in 13 of the 14 the tear was confirmed by surgical findings. In the six patients with an MR diagnosis of an intact TFC, surgical findings confirmed the diagnosis. MR imaging has emerged as the mainstay in imaging internal derangement of the soft tissues of the musculoskeletal system largely because of superior contrast

More recently, additional tear variations have been described, involving a displaced flap or bucket-handle of triangular fibrocartilage tissue, similar to bucket-handle meniscal tears in the knee.

However, triangular fibrocartilage complex (TFCC) tear is difficult to be diagnosed on MRI for its intrinsic small and thin structure with complex anatomy. The purpose of this article is to review the anatomy of TFCC, state of art MRI imaging technique, normal appearance and features of tear The triangular fibrocartilage complex (TFCC) is a complex structure which has historically been difficult to image and evaluate due to its small size and complexity. Recent advances in magnetic resonance (MR) imaging has enabled the visualization of the TFCC with increased spatial and contrast resolution. Abstract MR imaging has emerged as the mainstay in imaging internal derangement of the soft tissues of the musculoskeletal system largely because of superior contrast resolution. The complex geometry and diminutive size of the triangular fibrocartilage complex (TFCC) and its constituent structures can make optimal imaging of the TFCC challenging; therefore,
