What is a TFCC (Triangular Fibrocartilage Complex) injury?
First, the Triangular Fibrocartilage Complex (TFCC) is a critical structure located in the wrist,
specifically on the side of the pinky finger. It plays a role in stabilizing the wrist joint, particularly during activities that involve gripping or weight-bearing through the hands. It is comprised of a triangular fibrocartilage disc, ligaments, and associated structures. Importantly, the TFCC provides cushioning and stability between the 2 bones at the end of the forearm/beginning of the wrist (the radius and the ulna)
A closer look at the TFCC
The TFCC consists of several components, including the triangular fibrocartilage, the ulnar collateral ligament, and the dorsal and palmar radioulnar ligaments. These components work together to stabilize the wrist, absorb shock, and facilitate smooth movement between the radius and ulna. Especially, the complex is important for athletes and individuals who engage in activities requiring repetitive wrist motion or heavy lifting. Namely, it helps to prevent injuries in these high-stress situations.
How does the TFCC get injured?
TFCC injuries can occur due to various factors, primarily categorized into traumatic and degenerative causes. Traumatic injuries often result from a fall onto an outstretched hand, direct impact to the wrist, or sudden twisting motions. These injuries are common in sports such as gymnastics, football, and skiing. On the other hand, degenerative injuries, develop over time, often due to repetitive wrist motions or age related wear and tear. Medical conditions such as rheumatoid arthritis can also contribute to the deterioration of the TFCC.
Symptoms of a TFCC Injury
Individuals with a TFCC injury typically experience a range of symptoms. This can include but is not limited to:
- Pain, localized to the ulnar/pinky side of the wrist
- Worsened by gripping, twisting, or weight-bearing activities on the hand/wrist
- Swelling around the wrist
- Decreased range of motion in the wrist
- A feeling of instability in the wrist joint
- Clicking or popping sounds when moving the wrist
How is a TFCC Injury treated?
The treatment for TFCC injuries varies based on the severity and how it was injured. Primarily, conservative options are the first line of defense and often include rest, immobilization in a splint or brace, and physical therapy. Physical therapy goals include improving range of motion, strength, coordination, and a return to sport/activity plan. Pain management may involve the use of nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation. In cases where conservative treatments are ineffective, surgical intervention may be necessary. Surgical options can include debridement, repair, or, in severe cases, reconstruction of the TFCC itself.
Where can I find help?
In conclusion, a TFCC injury can significantly impact wrist function and quality of life. Early
intervention with appropriate treatment are the best options. The longer you leave the injury untreated, the trickier it becomes to return to your normal function and activities.
