What is the biomechanical function of the triangular fibrocartilage complex in the wrist?

It aids in blood circulation

It serves as a cushion and stabilizer

The triangular fibrocartilage complex (TFCC) plays a crucial role in the wrist's biomechanics by serving as a cushion and stabilizer. It is a structure composed of cartilage and ligaments located on the ulnar side of the wrist that helps to absorb forces transmitted through the wrist joint during movements and activities involving the hand. This cushioning effect is essential for protecting the wrist's bones and joints from excessive wear and tear, especially during high-impact activities or when gripping.

Additionally, the TFCC helps stabilize the distal radioulnar joint, contributing to the wrist's overall stability during movements that require rotation or load-bearing. This stabilization is vital for the functional use of the wrist and hand, allowing for a greater range of motion while minimizing the risk of injuries.
