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. Wrist support straps used in sports can also be used in mild cases to compress and minimize movement of the area.[10]. The TFC transmits and absorbs compressive forces. Suturing of the RUL’s this is, just like arthroscopic suturing of these ligaments, only possible when the damage is not too serious and if both ends of the ruptured ligament are not yet retracted. Imbriglia JE, Boland DS. She has also developed a conservative management protocol for the treatment of TFCC tears after 12 years of research around the globe. 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. The TFCC was found to be a homogenous structure composed 1~j; but not dissectab/e into, the articular disc, the dorsal and volar radioulnar … This attachment is mainly created by the RUL's of the TFCC. Methods. Patients with a positive ulnar variance are more susceptible to TFCC damage. The ulnar variance influences the amount of load that is transmitted through the distal ulna. Ulnar grind test: the forearm is fixated and the wrist is held in dorsiflexion. Triangular fibrocartilage complex (TFCC) injuries may be traumatic or degenerative in nature. This page was last edited on 14 November 2020, at 14:57. Traumatic disruption of the triangular fibrocartilage complex. To control the forearm rotation the DRUJ acts in concert with the proximal radioulnar joint. [1], The Palmer classification is the most recognized scheme; it divides TFCC lesions into these two categories. Die Enden von Elle (Ulna) und Speiche (Radius) des Arms werden darin fest miteinander und auch mit dem Handwurzelknochen verbunden. Histologic anatomy of the triangular fibrocartilage. The Triangular Fibrocartilage Complex is the ligamentous and cartilaginous structures that separate the radiocarpal from the distal radioulnar joint. The initial treatment for both traumatic and degenerative TFCC lesions, with a stable DRUJ, is conservative (nonsurgical) therapy. The triangular fibrocartilage complex (TFCC) is a differentiated fibroligamentary structure located between the ulnarhead, the lunate and the triquetrum on the ulnar side of the wrist. Even after a short period of time torn ligaments tend to retract and therefore lose length. The TFCC consists of an articular disc, meniscus homologue, ulnocarpal ligament, dosal & volar radioulnar ligament and extensor carpi ulnaris sheath.Origin: Medial border of distal radius Insertion: Base of ulnar styloid Vascular Supply: central disc is avascular, peripheral blood vessels penetrate TFCC margins Function of TFCC: 1. This procedure is indicated for DRUJ instability caused by an irreparable TFCC. Background and purpose: To investigate the outcome of open versus arthroscopic repair of injuries of the triangular fibrocartilage complex (TFCC). There is little information on these injuries in young athletes and a scarcity of data regarding their ability to return to preinjury levels of athletic participation. [9][8], Suturing TFCC ligaments can sometimes be performed arthroscopically. If there is a TFCC lesion the dye will leak from one joint compartment to another. Triangular fibrocartilage tears. Note: Imaging techniques can only be relevant together with the clinical findings of a carefully performed physical examination. The tendon graft is tunnelled through drilled holes in the ulnar and radius bones. Approximately one-fifth of the axial load of the wrist is transferred by the TFCC, and it is the most important stabilizer of the… The triangular fibrocartilage complex (TFCC) plays an important role in the stability and mobility of the ulnar side wrist. As the name suggests, the soft tissues of the wrist are complex. Other symptoms patients with a TFCC injury frequently mention are: swelling, loss of grip strength, instability and grinding or clicking sounds (crepitus) that can occur during activity of the wrist.[7]. The TFCC is made of tough fibrous tissue and cartilage. Its function is to provide stability, cushioning and smooth movement in the wrist joint. Der „triangular fibrocartilage complex“ (TFCC) stellt eine funktionell wichtige anatomische Struktur der Ulnarseite des Handgelenks dar. [citation needed], The ligaments are composed of longitudinally oriented lamellar collagen to resist tensile loads and have a rich vascular supply to allow healing. [2][3][4], The UCL's consist of the ulnolunate and the ulnotriquetral ligaments. The Triangular Fibrocartilage Complex (TFCC) is an area between your radius and ulna, the two main bones that make up your forearm. Arthroscopic debridement as a treatment for degenerative TFC tears associated with positive ulnar variance, unfortunately, show poor results. Radiographs are useful to diagnose or rule out possible bone fractures, a positive ulnar variance or osteoarthritis. Mild injuries of the TFCC may be referred to as a wrist sprain. : Triangular fibrocartilage complex, daher die Abkürzung TFCC), der auch ulnokarpaler Komplex genannt wird, ist eine dreieckig geformte Faserknorpelscheibe, die sich zwischen den Gelenkknochen des menschlichen Handgelenks befindet. Palpation: the best place to palpate the TFCC is between the extensor carpi ulnaris (ECU) and the flexor carpi ulnaris (FCU), distal to the ulnar styloid and proximal to the pisiform bone. The triangular fibrocartilage complex (TFCC) is a differentiated fibroligamentary structure located between the ulnarhead, the lunate and the triquetrum on the ulnar side of the wrist. Dorsal rotation injury, such as when a drill binds and rotates the wrist instead of the bit, can also cause traumatic injuries. The central part of the TFC has no blood supply and therefore has no healing capacity. Both parties are in fact right, as the RUL's consists of two ligaments each made of another two components: the superficial and the deep ligaments. Fax: 0201 - 371 90 84 biomechanics of TFCC 1, 4 overall, TFCC functions to stabilize distal radioulnar joint, and provide shock absorption between ulna and carpus (during axial loading of wrist and ulnar deviation of wrist) This study addressed the arthroscopic repair of peripheral tears in the TFCC, in a sample of 37 patients who were undergoing TFCC repair by wrist arthroscopy. Even though natural degeneration of the ulnocarpal joint is very common, it is important to recognize. Triangular fibrocartilage complex is a major stabilizer of the distal radioulnar joint (DRUJ). The triangular fibrocartilage complex consists of the triangular fibrocartilage disc, ulna meniscus, ulnar collateral ligament, carpal ligaments and the extensor carpi ulnaris tendon sheath. [citation needed], These ligaments arise from the distal radius medial border and insert on the ulna at two separate and distinct sites: the ulna styloid and the fovea (a groove that separates the ulnar styloid from the ulnar head). The Triangular Fibrocartilage Complex (TFCC) is fibrocartilage that is located on the small finger (ulnar) side of the hand. When a tear occurs in this area of the TFC, it typically creates an unstable flap of tissue that is likely to catch on other joint surfaces. These tears are a component of ulnar impaction syndrome. ZiFF - GmbH Current Concepts Review. An injury or tear to the TFCC can cause chronic wrist pain. [11] They are more taut during supination, because in supination ulnar styloid moves away from the carpal bones volar side.[1][5].
