A TFCC tear means you have hurt the triangular fibrocartilage complex in your wrist. This complex is a group of tissues, including ligaments, tendons, and cartilage, that connect the bones in your forearm to your wrist. You might tear your TFCC if you fall, twist your wrist, or break it. As you get older, this tissue can wear out and tear more easily.
What is TFCC?
The TFCC is made up of several parts:
The triangular fibrocartilage disc
The meniscus homologue
Dorsal and volar radioulnar ligaments
Ulnar collateral ligament
Ulnocarpal ligaments
These parts work together to keep the joint where your radius and ulna bones meet, as well as the ulnar side of your wrist, stable.
What is a TFCC tear?
A TFCC tear happens when the triangular fibrocartilage complex in your wrist gets damaged. This area is between the two big bones in your forearm, the radius and ulna.
