INTRODUCTION: In case of clinical suspicion of triangular fibrocartilage complex (TFCC) injury, different imaging techniques are used. The aim of this study was to determine whether MRA is superior to MRI and whether 3.0 T is better than 1.5 T (expresses in sensitivity, specificity and accuracy) in detecting TFCC injury, using arthroscopy as the gold standard. MATERIALS AND METHODS: The arthroscopic and MR findings of 150 patients who underwent arthroscopy for ulnar-sided wrist pain between January 2009 and November 2016 were retrospectively reviewed...

PURPOSE: Wrist arthroscopy is generally considered the reference standard in the diagnosis of triangular fibrocartilage complex (TFCC) injuries. There is a paucity of data examining the reliability of wrist arthroscopy as a diagnostic modality for TFCC injuries. The goal of this study was to evaluate the interobserver and intraobserver reliability of the diagnosis of TFCC pathology during wrist arthroscopy. METHODS: Twenty-five intraoperative digital videos were captured by the senior author during diagnostic and surgical arthroscopy of the wrist joint for known or suspected articular pathology...

BACKGROUND: The triangular fibrocartilage complex (TFCC) widens the radiocarpal joint and takes part in load transmission from the carpus to the forearm. It is thereby prone to degenerative changes. The painful situation that can accompany degeneration is called ulnar impaction. DIAGNOSIS: Clinical examination helps differentiate between various causes of ulnar-sided wrist pain. Standard X‑rays are needed to determine ulnar variance and stress radiographs can depict narrowing of the ulnocarpal joint space under load...

Triangular fibrocartilage complex (TFCC) injuries are increasingly recognized as a cause of ulnar-sided wrist pain. Palmer grouped these tears into either traumatic or degenerative, with various subclassifications. Magnetic resonance imaging (MRI), arthrogram, and arthroscopy are the methods used to establish the diagnosis. Several arthroscopic methods of TFCC repair including outside-in, inside-out, and all-inside techniques have been described. The outside-in repair, which involves piercing the TFCC via the ulnar side of the wrist, has been described by several authors, but the technique varies among authors with respect to instrumentation and subtle surgical modifications...

The aims of this study were to investigate the functional result and rate of osteoarthritis 15-25 years after a TFCC-repair. Forty-seven patients completed the questionnaire Patient Rated Wrist Evaluation (PRWE), and 43 had new X-rays. Fifty-seven percent had a simultaneous arthroscopy. Sixteen patients had later additional surgery to the wrist, of these eight had a reoperation of the TFCC-injury due to recurrent instability. Radiographs showed that 17.5% had developed radiocarpal osteoarthritis and 34% osteoarthritis in the distal radioulnar joint...

Clinopodium chinense (Benth.) O. Ktze (Labiatae), known as 'Duanxueliu' in the Chinese Pharmacopoeia, has been widely used as a traditional Chinese medicine for the treatment of hemorrhagic disease. Total flavonoids from Clinopodium chinense (Benth.) O. Ktze (TFCC), the most active ingredient, possess a variety of properties, such as antioxygenation. Until now, evidence-based toxicity data on TFCC has been limited. This study evaluated the acute (in mice and rat) and the 28-day repeated-dose (in rat) toxicity study of TFCC, respectively...

The triangular fibrocartilage complex (TFCC) is an intricate ligamentous and cartilaginous structure that helps transmit axial load across the wrist, and provide stability to the ulnocarpal and distal radioulnar joints (DRUJ). Because the blood supply to the TFCC varies depending on location, certain types of tears are more amenable to surgical repair than others. Since Palmer proposed his classification system of TFCC tears in 1989, only 1 case of a "bucket-handle" type tear has been reported. In this article, we describe two new cases of bucket-handle tears of the TFCC...

Injury of the triangular fibrocartilage complex (TFCC) is a common cause of ulnar-sided wrist pain. Volar and dorsal radioulnar ligaments and their foveal insertion are the most important stabilizing components of the TFCC. In irreparable tears, anatomic reconstruction of the TFCC aims to restore normal biomechanics and stability of the distal radioulnar joint. We proposed a novel arthroscopic-assisted technique using a palmaris longus tendon graft. Arthroscopic-assisted TFCC reconstruction is a safe and effective approach with outcomes comparable to conventional open reconstruction and may result in a better range of motion from minimizing soft tissue dissection and subsequent scarring...

The deep component of triangular fibrocartilage complex (TFCC) inserts onto the fovea of the ulnar head. This component is critical to provide distal radioulnar joint stability. The surgical techniques and results of transosseous inside-out TFCC foveal repair are discussed. The rewarding results encouraged the repair of TFCC to the fovea arthroscopically. Although the results are good, the factors of age (traumatic or degenerative) and quality of stump and TFCC proper, which relate to the results should be considered in the future...
