This test has defined stability based on age, height and bone density. Acta Ortopedica Mexicana in Spanish. Articles Cases Courses Quiz. The load transmission is directly proportional to this ulnar variance. The central part of the TFC has no blood supply and therefore has no healing capacity. MR imaging interpretation of the Palmer classification of triangular fibrocartilage complex lesions.

Fibrocartilago Triangular by pedro cervio on Prezi

To control the forearm rotation the DRUJ acts in concert with the proximal radioulnar joint. This discus is attached by thick tissue to the base of the ulnar styloid and by thinner tissue to the edge of the radius just proximal to the radiocarpal articular surface. In turn, the fibrocartilage balances various complex structures of the wrist, trlangular as carpal bones, and allows them to move in harmony.

It is a more invasive surgical technique compared to arthroscopic treatment, but the surgeon has better visibility and access to the TFCC. The goals of the procedure designed by Dr. Looking for beautiful books? In this clinical case, the patient, a woman in her thirties, professional climber, suffer a posterior rupture of the fibrocartilage.

El dolor del borde cubital de la muneca esta causado con frecuencia por roturas del fibrocartilago triangular FCT. Read it at Google Books – Find it at Amazon 5. If the fracture is treated surgically it is recommended to evaluate and if necessary repair the TFCC as well.


Reconstruction and evolution of dorsal triangular fibrocartilage complex ligament]. 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. In neutral ulnar variance, approximately 20 percent of the load is transmitted.

Cases with ulnar-negative variance had fewer degenerative changes. Check for errors and try again. Check out the top books of the year on our page Best Books of Anatomical terminology [ edit on Wikidata ].

Patients with a TFCC injury usually experience pain fbrocartilago discomfort located at the ulnar side of the wrist, often just above the ulnar styloid. The TFCC is important in load transmission across the ulnar aspect of the wrist.

These ligaments arise from the distal radius medial border and insert on the ulna at two separate and distinct sites: We use cookies to give you the best possible experience. This page was last edited on 12 Decemberat In pronation this is reversed: These tears are a component of ulnar impaction syndrome. The ulnar variance influences the amount of load that is transmitted through the distal ulna. The connection between the distal radius and the distal ulna, maintain the congruency of the DRUJ.

With positive ulnar variance it is reversed. There are two RUL’s, the palmar and dorsal radioulnar ligaments. Thus, puncturing the fibrocartilage, Dr. Multiples estudios han demostrado diferentes resultados utilizando estos procedimientos diagnosticos. CS1 Spanish-language sources es All articles with unsourced statements Articles with unsourced statements from December Articles with unsourced statements from April Injury may also occur from a distraction force applied to the volar forearm or wrist.


The role of the TFCC in supination and in pronation is a matter of dispute. Unable to process the form. One of the warning signs for this condition, besides the pain, is the instability in the wristie the feeling of abnormal movement inside that leads to failure of the executed action.

Fibrocartilago Triangular del Carpo

Application of an extension-pronation force to an axial-load wrist, such as in a fall on an outstretched hand, causes most of the traumatic injuries of the TFCC. Wrist support straps used in sports can also be used in mild cases to compress and minimize movement of the area.

These conclusions are opposite of those published by Af Ekenstam and Hagert. The TFCC has a substantial risk for injury and degeneration fibrocartolago of its anatomic complexity and multiple fiborcartilago.

Each ligament consists of a superficial component and a deep component. Rest can reduce pain and activity can make it worse, especially with rotating movements supination and pronation of the wrist or movements of the hand sideways in ulnar direction.

Dorsal rotation injury, such as when a drill binds and rotates the wrist instead of the bit, can also cause traumatic injuries.
