Triangular Fibrocartilage Complex (TFCC) Injuries

A Patient's Guide to Triangular Fibrocartilage Complex (TFCC) Injuries

Introduction

Triangular fibrocartilage complex (TFCC) injuries of the wrist affect the ulnar (little finger) side of the wrist. Mild injuries of the TFCC may be referred to as a wrist sprain. As the name suggests, the soft tissues of the wrist are complex. They work together to stabilize the very mobile wrist joint. Disruption of this area through injury or degeneration can cause more than just a wrist sprain. A TFCC injury can be a very disabling wrist condition.

This guide will help you understand

  • what parts if the wrist are involved
  • how these injuries occur
  • how doctors diagnose the condition
  • what treatment options are available

Anatomy

What parts of the wrist are involved?

The wrist is actually a collection of many bones and joints. It is probably the most complex of all the joints in the body. There are 15 bones that form connections from the end of the forearm to the hand.

The wrist itself contains eight small bones, called carpal bones. These bones are grouped in two rows across the wrist. The proximal row is where the wrist creases when you bend it. The second row of carpal bones, called the distal row, meets the proximal row a little further toward the fingers.

The proximal row of carpal bones connects the two bones of the forearm, the radius and the ulna, to the bones of the hand. On the ulnar side of the wrist, the end of the ulna bone of the forearm moves with two carpal bones, the lunate and the triquetrum.

The triangular fibrocartilage complex (TFCC) suspends the ends of the radius and ulna bones over the wrist. It is triangular in shape and made up of several ligaments and cartilage. The TFCC makes it possible for the wrist to move in six different directions (bending, straightening, twisting, side-to-side).

The entire triangular fibrocartilage complex (TFCC) sits between the ulna and two carpal bones (the lunate and the triquetrum). The TFCC inserts into the lunate and triquetrum via the ulnolunate and ulnotriquetral ligaments. It stabilizes the distal radioulnar joint while improving the range of motion and gliding action within the wrist.

There is a small cartilage pad called the articular disc in the center of the complex that cushions this part of the wrist joint. Other parts of the complex include the dorsal radioulnar ligament, the volar radioulnar ligament, the meniscus homologue (ulnocarpal meniscus), the ulnar collateral ligament, the subsheath of the extensor carpi ulnaris, and the ulnolunate and ulnotriquetral ligaments.

Injury to the triangular fibrocartilage complex involves tears of the fibrocartilage articular disc and meniscal homologue. The homologue refers to the piece of tissue that connects the disc to the triquetrum bone in the wrist. The homologue acts like a sling or leash between these two structures.
