Review of TFCC Injuries and Tears Introduction The Triangular Fibrocartilage Complex, or TFCC, is a load bearing ligamentous structure in the wrist that is prone to injury.
Review of TFCC Injuries and Tears The Triangular Fibrocartilage Complex, or TFCC, is a load bearing ligamentous structure in the wrist that is prone to injury. It is the most common cause of ulnar sided wrist pain. Injuries and tears can occur from acute trauma or more chronic degenerative causes.
The diagnosis is made by a combination of history, physical exam and appropriate imaging. Management is controversial and can be either conservative or surgical depending on a variety of factors including acuity, type or severity of symptoms and individual patient factors. Anatomy of the TFCC The TFCC is called a "complex" as it is derived from a variety of structures that collectively support the ulnar side of the wrist.
Broadly speaking, it is formed by the Triangular Fibrocartilage Disc (TFC), Radioulnar Ligaments (RULs), and Ulnocarpal Ligaments (UCLs). The Disc, which can be thought of as the "meniscus of the wrist", lies on the distal ulna and consists of chondroid fibrocartilage. The radioulnar ligaments stabilize the distal radioulnar joint.
The ulnocarpal ligaments stabilize the ulnocarpal joint. The TFCC is responsible for (a) load transmission and shock absorption across the ulnocarpal joint, (b) forearm rotation with a strong, flexible connection between distal radius and ulna, and (c) supports the ulnar portion of the carpus Mechanism of Injury The mechanism of injury involves different combinations of axial loading, rotation and radial or ulnar deviation. Causes can be broken down into traumatic or atraumatic/ degenerative.
Traumatic cases most commonly involve falling on a pronated, outstretched hand. Another traumatic cause can be a load compressed on the TFCC while in ulnar deviation, such as swinging a racket or bat.
If you are experiencing symptoms that may be related to tfcc injury review, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
