These ligaments support the joint through its arc of rotation. These ligaments arise from the distal radius medial border and insert on the ulna at two separate and distinct sites: In this regard, Dr.

Fibrocartilago Triangular del Carpo : Garcia Panos Juan Pedro :

These lesions common occur by patients with positive ulnar variance. If the fracture is treated surgically it is recommended to evaluate and if necessary repair the TFCC as well. MRI of the Upper Fibrpcartilago.

This test has defined stability based on age, height and bone density.

Fractures of the radius bone are fibrocartilayo associated by TFCC damage. The Journal of Hand Surgery. MR imaging interpretation of the Palmer classification of triangular fibrocartilage complex lesions. Synonyms or Alternate Spellings: The TFC is an articular discus that lies on the pole of the distal ulna. 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.

But only if there is no serious damage to the ligaments or other surrounding structures. Indications for acute TFCC surgery are: In pronation this is reversed: Rtiangular ligaments are composed of longitudinally oriented lamellar collagen to resist tensile loads and have a rich vascular supply to allow healing.


Support Radiopaedia and see fewer ads. The triangular fibrocartilage complex TFCC is a complex structure that is a major contributor to the stability of the wrist. There are two RUL’s, the palmar and dorsal radioulnar ligaments. The central part of the TFC has no blood supply and therefore has no healing capacity. Open surgery is usually required for degenerative or more complex TFCC injuries, or if additional damage to the wrist or forearm caused instability or displacement. These conclusions are opposite of those published by Af Ekenstam and Hagert.

The load transmission is directly proportional to this ulnar variance. Arthroscopic debridement as a treatment for degenerative TFC tears associated with positive ulnar variance, unfortunately, show poor results.

The superficial components insert directly onto the ulna styloid. Articles Cases Courses Quiz. Home Contact Us Help Free delivery worldwide. Check out the top trianbular of the year on our page Best Books of Some authors Schuind et al. A successful approach of her situation requires to set the exact location of the tearing and its characteristics. Injuries to the TFCC 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.

La artroscopia de muneca es considerada por muchos radiologos y cirujanos la referencia “standard.

FIBROCARTILAGO TRIANGULAR by Alejandro Quintela Aguado on Prezi

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. Thus, puncturing the fibrocartilage, Dr.

During supination, the superficial palmar and the deep dorsal ligaments are tightened [ citation needed ]preventing palmar translation of the ulna.


K; Chang, D; Plate, A. Dispatched from the UK in 4 business days When will my order arrive? In this clinical case, the patient, a woman in her thirties, professional climber, suffer a posterior rupture of the fibrocartilage.

Reconstruction and evolution of dorsal triangular fibrocartilage complex ligament].

The procedure is successful, allowing the patient to resume the practice of professional fibrocartilaago. Even though natural degeneration of the ulnocarpal joint is very common, it is important to recognize. Both parties are in fact right, as the RUL’s consists of two ligaments each made of another two components: Dorsal rotation injury, such as when a drill binds and rotates the wrist instead of the bit, can also cause traumatic injuries.

Chronic and excessive loading through the ulnocarpal joint, causes degenerative TFCC tears. Edit article Share article View revision history. The deep components insert more lateral, into the fovea adjacent to the articular surface of the pole of the distal ulna.

From Wikipedia, the free encyclopedia. The central portion of the TFC is thin and consists of chondroid fibrocartilage; this type of tissue is often seen in structures that can trinagular compressive loads. These ligaments prevent dorsal migration fbrocartilago the distal ulna. In neutral ulnar variance, approximately 20 percent of the load is transmitted.
