Cartilage of Wrisberg, also known as the meniscus homologue or the triangular fibrocartilage complex (TFCC), is a structure located in the wrist joint. It refers to a specific area of cartilage that is found in the proximal carpal row, on the ulnar side of the wrist.
This cartilage structure serves as an important component in maintaining the stability and functionality of the wrist joint. It consists of several components, including the triangular fibrocartilage, the ulnar collateral ligament, the meniscus homologue, as well as various associated ligaments and tendons.
The main function of the Cartilage of Wrisberg is to provide support and strengthen the connection between the ulna bone and the carpals, which are the small bones in the wrist. It acts as a shock absorber, dissipating forces during wrist movement and minimizing the risk of injury. The Cartilage of Wrisberg also plays a crucial role in maintaining proper alignment and smooth movement of the wrist joint.
Injury or degeneration of the Cartilage of Wrisberg can lead to wrist instability, pain, and limited range of motion. Common causes of damage include trauma, repetitive strain, or natural aging. Treatment options for Cartilage of Wrisberg injuries may include conservative methods such as rest, immobilization, physical therapy, and medication. In some cases, surgical intervention may be required, including procedures to repair or reconstruct the damaged cartilage.
