Zeid Al-Ani, Syed Ali, Simon Beardmore, Vinay Parmar, Teik Chooi Oh
BACKGROUND: Although subspecialist orthopaedic surgeons usually request Magnetic Resonance Arthrogram (MRA) examinations, some orthopaedic surgeons may request this examination for a body part that is different from their subspecialty. The purpose of the study is to compare the MRA and the clinical findings in the subspecialist and non-subspecialist groups. METHOD: Retrospective analysis of MRA examinations over a 6-month period. Findings were compared with the clinical information...

Ulnar-sided wrist pain can be a challenging entity for the hand surgeon and even more so in the athletic population. The authors present 8 causes of ulnar-sided wrist pain in an athlete (hook of hamate fracture, pisiform fracture, hypothenar hammer syndrome, triangular fibrocartilage complex injuries, ulnocarpal impaction syndrome, lunotriquetral ligament tears, extensor carpi ulnaris tendinitis, subluxation of extensor carpi ulnaris) and their associated imaging and treatment options.

The importance of foveal repair of the triangular fibrocartilage complex (TFCC) on stability of the distal radioulnar joint (DRUJ) has been emphasized with increasing knowledge of the anatomy and biomechanics of the TFCC and DRUJ. Although both open and arthroscopic techniques have been described for improving DRUJ stability, there has been a marked evolution of arthroscopic TFCC repair technique with successful clinical outcome. Recently, an arthroscopic trans-osseous technique has been described to repair foveal tears of the TFCC...

INTRODUCTION: Fractures of the distal radius account for 15% of all fractures. The use of arthroscopy is increasingly popular in the last years, with the goal to achieve a better anatomical reduction of the articular fragments. SOURCES OF DATA: We searched the literature on Medline (PubMed), Web of Science and Scopus databases using the combined keywords 'wrist', 'distal radial fracture', 'distal radius fracture' and 'arthroscopy'. Twenty-eight studies were identified...

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 wrist protocol, there are specific techniques used to optimize 3T imaging of the wrist; including driven equilibrium sequence (DRIVE), parallel imaging, and 3D imaging...

Treatments for acute distal radioulnar joint (DRUJ) instability with distal radius fracture vary from conservative to operative treatment, although it seems to be no consensus regarding which treatment is optimal. This prospective randomized study was designed to compare the clinical outcomes for operative and conservative treatment of acute DRUJ instability with distal radius fracture, according to the presence or absence and type of ulnar styloid process fracture and the degree of its displacement. Between July 2008 and February 2013, we enrolled 157 patients who exhibited an unstable DRUJ during intraoperative manual stress testing (via the ballottement test) after fixation of the distal radius...

OBJECTIVE: Arthroscopic decompression (wafer procedure) of the ulnocarpal compartment in patients with ulnar impaction syndrome. INDICATIONS: The arthroscopic wafer procedure is recommended in ulnar-plus situations with up to 3 mm length-excess. To perform this procedure the ulnar head needs to be accessible for the burr through a pre-existing, impaction-related, centroradial lesion of the triangular fibrocartilage complex (TFCC). The additional presence of a distal radioulnar joint (DRUJ) type C confirms the indication...

OBJECTIVE: The goal of this operation technique is a stable refixation of the triangular fibrocartilage complex (TFCC) to the fovea ulnaris. The stability of the distal radio-ulnar joint (DRUJ) should be re-established. The patients pain and the feeling of instability should be reduced. INDICATIONS: Lesions of the foveal component of the TFCC resulting in DRUJ instability. Combined lesions of both components of the TFCC. Complete detachment of the TFCC from the ulna either without fracture of the styloid process of the ulna or with fracture (floating styloid)...

We investigated the reliability and accuracy of the distal radioulnar joint (DRUJ) ballottement test using five fresh-frozen cadaver specimens in triangular fibrocartilage complex (TFCC)-intact, and TFCC-sectioned wrists. The humerus and proximal ulna were fixed. The ulna was allowed to translate in dorsopalmar directions without rotation, and the radius was allowed to move freely. Four sensors of a magnetic tracking system were attached to the radius and ulna, and the nails of each examiner's thumbs. Five examiners conducted the DRUJ ballottement test before and after TFCC sectioning...

BACKGROUND: Disruption of the triangular fibrocartilage complex (TFCC) foveal insertion can lead to distal radioulnar joint (DRUJ) instability accompanied by ulnar-sided pain, weakness, snapping, and limited forearm rotation. We investigated the clinical outcomes of patients with TFCC foveal tears treated with arthroscopic-assisted repair. MATERIALS AND METHODS: Twelve patients underwent foveal repair of avulsed TFCC with the assistance of arthroscopy between 2011 and 2013...

We present a series of eight patients who underwent wrist arthroscopy for presumed solitary tears of the triangular fibrocartilage (TFC) and were, instead, found to have combined 1A (central tear) and 1B (ulnar avulsion) tears. The Palmer Classification does not currently categorize this combined pattern. All but one patient had a traumatic injury. Each subject had preoperative radiographs and MRI scans. TFC tears were evident on all MRI scans, though only one was suggestive of a combined tear pat - tern. Surgical management included arthroscopic central tear debridement and ulnar peripheral repair...
