From September 1996 to September 2001, 37 adult patients were diagnosed with chronic triangular fibrocartilage complex (TFCC) tears with distal radioulnar joint (DRUJ) instability in our clinic. They had all received the procedure of TFCC reconstruction with partial extensor carpi ulnaris (ECU) combined with or without ulnar shortening. There were 36 males and one female in the study with a mea...

Various authors have documented wrist ligament injuries in patients with distal radius fractures (DRFs). We conducted a study to determine whether scapholunate interosseous ligament (SLIL), triangular fibrocartilage complex (TFCC), or chondral injuries directly assessed with arthroscopy predict DRF outcomes. Forty-two patients who underwent open reduction and internal fixation of DRFs were enro...

BACKGROUND AND PURPOSE Mechanisms of injury to ulnar-sided ligaments (stabilizing the distal radioulnar joint and the ulna to the carpus) associated with dorsally displaced distal radius fractures are poorly described. We investigated the injury patterns in a human cadaver fracture model. METHODS Fresh frozen human cadaver arms were used. A dorsal open-wedge osteotomy was performed in the dis...

PURPOSE To determine whether traumatic triangular fibrocartilage complex (TFCC) tears treated by arthroscopic repair have improved functional outcome scores, range of motion, grip strength, and pain relief compared with those repaired using an open surgical technique. METHODS From 1997 to 2006, 75 patients had repair of traumatic TFCC tears. Thirty-six patients had arthroscopic TFCC repair, a...

The distal radioulnar joint (DRUJ) acts in concert with the proximal radioulnar joint to control forearm rotation. The DRUJ is stabilized by the triangular fibrocartilage complex (TFCC). This complex of fibrocartilage and ligaments support the joint through its arc of rotation, as well as provide a smooth surface for the ulnar side of the carpus. TFCC and DRUJ injuries are part of the common pa...

INTRODUCTION: Fractures of the distal radius are the most common fracture of both adults and children. Distal radius fractures frequently heal with residual displacement and angulation with cast treatment and often cause distal radioulnar joint dysfunction including pain, decreased rotation, weakness, and arthritis. In spite of the frequency of these injuries, the indications for surgical treat...

DRUJ arthroscopy was rarely reported compared with radiocarpal or midcarpal joint arthroscopy. We describe our technique, and findings of DRUJ scope for DRUJ instability cases. Technique: The portal was made at a very distal area of the DRUJ, just proximal of the TFCC surface. The 1.9 mm oblique view arthroscope was used. Curved blunt mosquito forceps were firstly inserted to the DRUJ through t...

BACKGROUND Soft tissue injuries associated with distal radius fractures have been reported by some authors. Arthroscopy can be used to evaluate the condition of the articular surface and intracarpal soft tissues and as an aid to treatment. There are three intracarpal soft tissues of particular importance: the triangular fibrocartilage complex (TFCC), the scapholunate interosseous ligament (SLIL...
