TFCC Tear
TFCC Tear
The wrist has a crucial structure called the Triangular FibroCartilage Complex, or TFCC. The TFCC is constructed of cartilage and thick fibrous tissue. The stability of the joints between the ulna and radius ends of the forearm bones is increased by the support provided by this tissue. The little bones on the ulnar side (sometimes known as the “pinkie finger” side) of the wrist are likewise connected to the forearm by the TFCC. The TFCC is made up of a variety of tissues that work together to stabilize the ulnar side of the wrist.
WHAT ARE THE SYMPTOMS?
Some people may not experience any discomfort or wrist instability issues due to a TFCC tear. Often, MRI studies show tears in people with no pain or problems using the wrist.
Some or all of the following symptoms may also be felt by other people:
- Clicking or popping while turning the forearm or moving the wrist from side to side
- Pain
- Weakness
- Limited motion
An issue with the TFCC may be indicated by pain or instability in the wrist. In this situation, talking with your doctor can assist to make things clearer.
WHAT ARE THE CAUSES & RISK FACTORS?
TFCC tear is normally due to natural wear, and the other is usually from injury. The most frequent type of tears, wear-related tears, are typically not present in younger people. They grow more frequent as one ages.
Tears caused by trauma might stem from:
- A fall on the hand or wrist
- A twisting injury (like a drill bit catching, causing a twist of the arm)
- A fracture at the end of the radius
