The triangular fibrocartilage complex tfcc is formed by the triangular fibrocartilage discus tfc the radioulnar ligaments ruls and the ulnocarpal ligaments ucls.

Triangular fibrocartilage complex cadaver. The triangular fibrocartilage complex was unaffected in only of the patients older than 70 years. Journal of hand surgery. An injury or tear to the tfcc can cause chronic wrist pain. The triangular fibrocartilage complex tfcc is a cartilage structure located on the small finger side of the wrist that cushions and supports the small carpal bones in the wrist.

Trehan sk wall lb calfee rp shen ts dy cj yannascoli sm goldfarb ca. The triangular fibrocartilage complex is the ligamentous and cartilaginous structures that separate the radiocarpal from the distal radioulnar joint. The triangular fibrocartilage complex tfcc is a complex structure that is a major contributor to the stability of the wrist. Previous studies found a correlation between age and abnormalities 10 17 in cadavers and asymptomatic patients.

Medial border of distal radius. Type i lesions are subclassified as a to d based on the tear location and fracture association. Gross anatomy the tfcc is located on the ulnar aspect of the wrist joint between the ulna and the lunate and triquet. The tfcc consists of an articular disc meniscus homologue ulnocarpal ligament dorsal volar radioulnar ligament and extensor carpi ulnaris sheath.

Triangular fibrocartilage complex tfcc injuries are classified based on their cause and location. Background although foveal tears of the triangular fibrocartilage complex tfcc can be surgically reattached to the fovea via a dorsal approach the foveal lesion is difficult to visualize from the dorsal side because the extensor carpi ulnaris ecu sheath floor and the superficial dorsal limb of the radioulnar ligament hinders the view of the fovea. The triangular fi brocartilage complex tfcc is one of the intrinsic ligaments of the wrist. It is often injured due to a fall on an outstretched hand or in association with distal radius fractures and central perforations are commonly seen in degenerative processes during aging.

The tfcc keeps the forearm bones radius and ulna stable when the hand grasps or the forearm rotates. This review also shows that abnormality rate increases in symptomatic patients. We found an increasing prevalence of triangular fibrocartilage complex abnormalities diagnosed by various modalities. Arthroscopic diagnosis of the triangular fibrocartilage complex foveal tear.

The triangular fibrocartilage complex tfcc consists of the articular disc meniscus homolog dorsal and volar radioulnar ligaments ulnocarpal ligaments ulnar joint capsule and extensor carpi ulnaris subsheath. The palmer classification 1 divides tfcc injuries into types i acute and ii degenerative. Normal tfcc anatomy facilitates smooth forearm and wrist motion.
