During supination, the superficial palmar and the deep dorsal ligaments are tightened [ citation needed ]preventing palmar translation of the ulna. It is a more invasive surgical technique compared to arthroscopic treatment, but the surgeon has better visibility and access to the TFCC.

Sin embargo, la continua controversia sobre la aproximacion diagnostica a este problema clinico, la eleccion de la modalidad de imagen mas apropiada para evaluar el fibrocartilago triangular del carpo, aun presenta un dilema diagnostico.

Canadian Journal of Surgery. She has also developed a conservative management protocol for the treatment of TFCC tears after 12 years of research around the globe. Injuries to the Tgiangular may be preceded by a fall on a pronated outstretched arm; a rotational injury to the forearm; an axial load trauma to the wrist; or a distraction injury of the wrist in ulnar direction.

Journal of Orthopaedic Surgery.

Imaging techniques can only be relevant together with the clinical findings of a carefully performed physical examination. The TFCC has a substantial risk for injury and degeneration because of its anatomic complexity and multiple functions.

They originate from the ulnar styloid and insert into the carpal bones of the wrist: Log in Sign up. Support Radiopaedia and see fewer ads. Injury may also occur from a distraction force applied to the volar forearm or wrist. Even after a short period of time torn ligaments tend to retract and therefore lose length. In this regard, Dr. Thus, puncturing the fibrocartilage, Dr. Read it at Google Books – Find it at Amazon 6. Both parties are in fact right, as the RUL’s consists of two ligaments each made of another two components: Read it at Google Books – Find it at Amazon 5.


The Palmer classification is the most recognized fibrocartulago it divides TFCC lesions into these two categories. Even though natural degeneration of the ulnocarpal joint is very common, it is important to recognize.

Retracted ligament ends are impossible to suture together again and a reconstruction may be necessary.

Cases with ulnar-negative variance had fewer degenerative changes. Dorsal rotation injury, hriangular as when a drill binds and rotates the wrist instead of the bit, can also cause traumatic injuries.

Fibrocartilago Triangular del Carpo : Garcia Panos Juan Pedro :

The triangular fibrocartilage complex TFCC is a complex structure that is a major contributor to the stability of the wrist. Pitfalls that may mimic injuries of the triangular fibrocartilage and proximal fbirocartilago wrist ligaments at MR imaging.
