This study is intended as a review of 3Tesla (T) magnetic resonance (MR) imaging of the triangular fibrocartilage complex (TFCC). The recent advances in MR imaging, which includes high field strength magnets, multi-channel coils, and isotropic 3-dimensional (3D) sequences have enabled the visualization of precise TFCC anatomy with high spatial and contrast resolution. In addition to the routine...

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, insid...

PURPOSE To evaluate high-resolution MRI of the triangular fibrocartilage complex (TFCC) at 3T using a surface coil (SC) or volume coil (VC). MATERIALS AND METHODS MRI was obtained from nine volunteers in the supine position with a 3-inch SC and in prone position with a transmit-receiver wrist VC at 3 T. Coronal two-dimensional-gradient echo (2D-GRE) images (TR/TE/FA = 500 msec/15 msec/40 degr...

From September 1996 to September 1997, 27 adult patients were diagnosed with chronic triangular fibrocartilage complex (TFCC) tears with distal radioulna joint (DRUJ) instability in our clinic. They all received the procedure of TFCC reconstruction with partial extensor carpi ulnaris (ECU) tendon combined with or without ulnar shortening. There were 26 males and one female in the study with a m...

Thirty-five of the 49 patients also underwent fluoroscopy-guided 3T MR arthrography of the wrist joint using a gadolinium/saline contrast mix. Arthroscopy found TFCC tears in 22 patients, scapholunate tears in 18, and lunatotriquetral tears in 11. Nineteen TFCC tears, 16 scapholunate tears, and nine lunatotriquetral tears were seen on 3T MRI. There were no false-positive readings on MRI compare...

BACKGROUND AND PURPOSE To investigate the outcome of open versus arthroscopic repair of injuries of the triangular fibrocartilage complex (TFCC). METHODS An electronic literature search of articles published between January 1, 1985, and May 26, 2016, in PubMed, Embase, and the Cochrane Library was carried out in May 2016 and updated in March and December 2017. Studies comparing open and arthr...

INTRODUCTION Ulnar variance affects the force distribution across the wrist and is related with some ulnar pathologies. Ulnar minus variance is associated with Kienböck’s disease, whereas ulnar plus variance plays an important role in triangular fibrocartilage complex (TFCC) tear and ulnar impaction syndrome. Ulnar variance is measured based on plain radiograph. However, plain radiograph shows ...

Background Although foveal tears of the triangular fibrocartilage complex (TFCC) can be surgically reattached to the fovea via a dorsal approach, the foveal lesion is difficult to visualize from the dorsal side because the extensor carpi ulnaris (ECU) sheath floor and the superficial dorsal limb of the radioulnar ligament hinders the view of the fovea. Materials and Methods Twenty-one patients ...

Doxorubicin has cardiotoxic effects that limit its clinical benefit in cancer patients. This study aims to investigate the protective effects of the total flavonoids from Clinopodium chinense (Benth.) O. Ktze (TFCC) against doxorubicin- (DOX-) induced cardiotoxicity. Male rats were intraperitoneally injected with a single dose of DOX (3 mg/kg) every 2 days for three injections. Heart samples we...

PURPOSE To measure the effects of distal radius malalignment on loading at the distal ulna. METHODS Using an adjustable mechanism to simulate angulated and translated malalignments, clinically relevant distal radius deformities were simulated in a cadaveric model. A custom-built load cell was inserted just proximal to the native ulna head to measure the resultant force and torque in the dista...
