The TFCC has a substantial risk for injury and degeneration because of its anatomic complexity and multiple functions. 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. Articles Cases Courses Quiz. If the fracture is treated surgically it is recommended to evaluate and if necessary repair the TFCC as well.

These ligaments support the joint through its arc of rotation. Journal of Orthopaedic Surgery. 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.
Fibrocartilago Triangular del Carpo : Garcia Panos Juan Pedro :
The goals of the procedure designed by Dr. 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. Even though natural degeneration of the teiangular joint is very common, it is important to recognize.
In neutral ulnar variance, approximately 20 percent of the load is transmitted. Suturing TFCC ligaments can sometimes be performed arthroscopically.

The procedure is successful, allowing the patient to resume the practice of professional climbing. Acta Ortopedica Mexicana in Spanish. La artroscopia de muneca es considerada por muchos radiologos y cirujanos la referencia “standard.
The Journal of Hand Surgery 0: Chronic and excessive loading through the ulnocarpal joint, causes degenerative TFCC tears. Arthroscopic debridement as a treatment for degenerative TFC tears associated with positive ulnar variance, unfortunately, show poor results. These ligaments arise from the distal radius medial border and insert on the ulna at two separate and distinct sites: Imaging techniques can only be relevant together with the clinical findings of a carefully performed physical examination.
They are more taut during supinationbecause in supination ulnar styloid moves away from the carpal bones volar side. During supination, the superficial palmar ribrocartilago the deep dorsal ligaments are tightened [ citation needed ]preventing palmar translation of the ulna. Log in Sign up. Other symptoms patients with a TFCC injury frequently mention are: Physiotherapy and Occupational Therapy can help patients recover after immobilization or surgery.
Even after a short period of time torn ligaments tend to retract and therefore lose length. Green’s Operative Hand Surgery 7th ed. 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.
Retracted ligament ends are impossible to suture together again and a reconstruction may be necessary. Looking for beautiful books?
The Journal of Hand Surgery. Reconstruction and evolution of dorsal triangular fibrocartilage complex ligament]. The connection between the distal radius and the distal ulna, maintain the congruency of the DRUJ. Perforations and defects in the TFCC are not all traumatic.
Removing the damaged tissue debridement is then indicated. TFCC surgery is also indicated when conservative treatment proves insufficient in about 8—12 weeks. There are two RUL’s, the palmar and dorsal radioulnar ligaments.
