What is a TFCC tear?
The triangular fibrocartilage complex (TFCC) connects the bones in your forearm with bones in your wrist. The structure — made up of ligaments, tendons and cartilage — helps support and stabilize your wrist. You can tear your TFCC if you fall on, twist or fracture your wrist. TFCC tears can also result from tissue wearing down as you age.
What is the function of the TFCC?
It attaches your forearm bones (ulna and radius) to each other and to the small bones of your wrist. Your TFCC helps stabilize, support and cushion your wrist. You can rotate your wrist and grip objects tightly thanks to your TFCC. When you tear your TFCC, your wrist joint may feel weaker and less stable.
What is the TFCC made of?
The Triangular FibroCartilage Complex, or TFCC, is an important structure in the wrist. The TFCC is made of tough fibrous tissue and cartilage. This tissue supports the joints between the end of the forearm bones (radius and ulna), adding to their stability.

Where is the TFCC on the wrist?
The TFCC is located on the ulnar aspect of the wrist joint between the ulna and the lunate and triquetrum of the proximal carpal row. It has an elongated triangular shape with the apex pointing at the radius 5 and consists of the triangular fibrocartilage disc proper along with 1,2:
