A TFCC injury can be a very disabling wrist conditio… Dorsal rotation injury, such as when a drill binds and rotates the wrist instead of the bit, can also cause traumatic injuries. The TFCC keeps the forearm bones (radius and ulna) stable when the hand grasps or the forearm rotates. Retracted ligament ends are impossible to suture together again and a reconstruction may be necessary. The Triangular fibrocartilage complex (TFCC) is formed by the triangular fibrocartilage discus (TFC), the radioulnar ligaments (RULs) and the ulnocarpal ligaments (UCLs). To control the forearm rotation the DRUJ acts in concert with the proximal radioulnar joint. [6], The TFCC is a major stabilizer of the DRUJ. The TFCC is a complex structure consisting of the triangular fibrocartilage (TFC) disc proper, ulnomeniscal homologue and numerous ligaments and tendons. Wendy Medeiros, OTR, CHT(ret) has designed a weight-bearing test to objectively analyze the stability of the wrist. Die Enden von Elle (Ulna) und Speiche (Radius) des Arms werden darin fest miteinander und auch mit dem Handwurzelknochen verbunden. Traumatic injury or a fall onto an outstretched hand is the most common mechanism of injury. This study was performed to determine the prevalence of triangular fibrocartilage complex (TFCC) injuries as shown by 3.0T magnetic resonance imaging (MRI) in patients with distal radius fractures. The Triangular Fibrocartilage Complex (TFCC) is a ligament and cartilage structure that connects the radius and ulna, and the wrist to the forearm.

Tel. DRUJ stress test: with this provocation manoeuver the wrist is held in pronated or supinated position, while the physician attempts to manipulate the distal ulna in dorsal and volar direction. Tiny as it is, the TFCC is an essential component in your wrist for gripping objects like a baseball bat, for weight-bearing exercises, and any wrist rotation exercise such as tennis. Der trianguläre fibrokartilaginäre Komplex (engl. These injuries are classified based on the chronicity of the injury and the location of the tear, and the Palmer classification is most commonly used. If there is a TFCC lesion the dye will leak from one joint compartment to another. Shortening the ulnar bone may help relieve the excess pressure to the TFCC and prevent further degeneration. The Triangular Fibrocartilage Complex (TFCC) is fibrocartilage that is located on the small finger (ulnar) side of the hand. This positive ulnar variance occurs during pronation. A TFCC tear is an injury to the Triangular Fibrocartilage Complex, found in the wrist, between the end of the Ulna bone and the Carpals. Approximately one-fifth of the axial load of the wrist is transferred by the TFCC, and it is the most important stabilizer of the… Note: Imaging techniques can only be relevant together with the clinical findings of a carefully performed physical examination. Tears of the triangular fibrocartilage complex (TFCC) are relatively common but can be difficult to diagnose and treat. [citation needed]. If the fracture is treated surgically it is recommended to evaluate and if necessary repair the TFCC as well. Nonoperative management can be effective for certain injury patterns. The deep components insert more anterior, into the fovea adjacent to the articular surface of the dome of the distal ulna. Injury may also occur from a distraction force applied to the volar forearm or wrist. But only if there is no serious damage to the ligaments or other surrounding structures. Types of triangular fibrocartilage complex (TFCC) tears or sprains . The triangular fibrocartilage complex of the wrist was serially sectioned for routine histology. They originate from the ulnar styloid and insert into the carpal bones of the wrist: the ulnolunate ligament inserts into the lunate bone and the ulnotriquetral ligament into the triquetrum bone. Chronic and excessive loading through the ulnocarpal joint, causes degenerative TFCC tears. The initial treatment for both traumatic and degenerative TFCC lesions, with a stable DRUJ, is conservative (nonsurgical) therapy. D 45327 Essen In total, 57 patients with distal radius fractures underwent 3.0T MRI examinations to observe the incidence of TFCC injuries after manual reduction and cast fixation. With positive ulnar variance it is reversed. Shortening of the ulnar bone.
