Cases with ulnar-negative variance had fewer degenerative changes. In this clinical case, the patient, a woman in her thirties, professional climber, suffer a posterior rupture fibrocaryilago the fibrocartilage. The ligaments are composed of longitudinally oriented lamellar collagen to resist tensile loads and have a rich vascular supply to allow healing.
Open surgery is usually required for degenerative or more complex TFCC injuries, or if additional damage to the wrist or forearm caused instability or tringular. If the fracture is treated surgically it is recommended to evaluate and if necessary repair the TFCC as well. Unable to process the form. Check for errors and try again. TFCC surgery is also indicated when conservative treatment proves insufficient in about 8—12 weeks.
Finally tears of the Fibroocartilago are frequently found by patients with distal radius fractures.
About Blog Go ad-free. She has also developed a conservative management protocol for the treatment of TFCC tears fibrocartioago 12 years of research around the globe.
However, there are also some patients who report diffuse pain throughout the entire wrist. The TFC is an articular discus that lies on the pole of the distal ulna. Description El diagnostico de pacientes con dolor de muneca sin lesiones oseas es un desafio tanto para el radiologo como para el cirujano de la mano. The objectives The goals of the procedure designed by Dr.
Even after a short period of time torn ligaments tend to retract and therefore lose length. To control the forearm rotation the DRUJ acts in concert with the proximal radioulnar joint. The ulnar variance influences the amount of load that is transmitted fibrocartilqgo the distal ulna. Looking for beautiful books?
In pronation this is reversed: This positive ulnar variance occurs during pronation. In turn, the fibrocartilage balances various complex structures of the wrist, such as carpal bones, and allows them to move in harmony. This occurs during supination, because the radius moves distally on the ulna and creates triangu,ar negative ulnar variance.

Arthroscopic debridement as a treatment for degenerative TFC tears associated with positive ulnar variance, unfortunately, show poor results. MR imaging interpretation of the Palmer classification of triangular fibrocartilage complex lesions. The central portion of the TFC is thin and consists of chondroid fibrocartilage; this type of tissue is often seen in structures that can bear compressive loads.
The central part of the TFC has no blood supply fibrocaritlago therefore has no healing capacity. The procedure is successful, allowing the patient to resume the practice of professional climbing.
Fibrocartilage injuries are especially constraining, given its role in the loads distribution of the upper limb, helping also to absorb and distribute the force exerted when tightening the fist, grasping an object, etc. These ligaments prevent dorsal migration of the distal ulna. They are more taut during supinationbecause in supination ulnar styloid moves away from the carpal bones volar side. But only if there is no serious damage to the ligaments or other surrounding structures.
The role of the TFCC in supination and in pronation is a matter of dispute. Canadian Journal of Surgery.
Fibrocartilago Triangular by pedro cervio on Prezi
The deep components insert more lateral, into the fovea adjacent to the articular surface of the pole of the distal ulna. Synonyms or Alternate Spellings: With positive ulnar variance it is reversed.
Patients may be advised to wear a temporary splint or cast to immobilize the wrist and forearm for four to six weeks. Both parties are in fact right, as the RUL’s consists of two ligaments each made of another two components: Fbirocartilago classification provides an accurate anatomic description of tears, it does not guide treatment or indicate prognosis.

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.

You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Fibrocartilqgo conclusions are opposite of those published by Af Ekenstam and Hagert.
Edit article Share article Fibrocartilagk revision history. 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.
