What is TFCC anatomy?

What is TFCC anatomy?

The triangular fibrocartilage complex (TFCC) is a significant structure in the ulnar side of the wrist. Serving as the primary stabilizer of the distal radius ulnar joint (DRUJ), it also acts as a load-bearing structure.

What is the mechanism of a TFCC injury?

Injury Mechanism: The TFCC is stressed during axial loading, ulnar deviation, and extremes of forearm rotation or wrist extension. A single traumatic event and/or a repetitive strain with the aforementioned mechanism can lead to degeneration.

What is the function of the TFCC?

Biomechanical studies suggest that the TFCC functions both as a cushion for the ulnar carpus and as a major stabilizer of the distal radioulnar joint. Perforations of the TFCC can result in the ulna-lunate abutment and cartilage erosion.

What is TFCC ligament?

The triangular fibrocartilage complex (TFCC) is an area between your radius and ulna, the two main bones that make up your forearm. Your TFCC is made of several ligaments and tendons, as well as cartilage.

Where is the TFCC ligament?

The triangular fibrocartilage complex (TFCC) is a network of ligaments, tendons, and cartilage that sits between the ulna and radius bones on the small finger side of the wrist. The TFCC stabilizes and cushions the wrist, particularly when a person rotates their hand or grasps something with it.

What does DRUJ stand for?

Conditions. DRUJ stand for ‘Distal Radio-ulnar Joint’ . The radius and ulna bones in the forearm form a closed loop with a proximal joint at the elbow and a distal joint at the wrist. The DRUJ is stabilised primarily by the strong ligaments surrounding it and secondarily by the congruency of the bony surfaces.

How do you treat a TFCC injury?

TFCC can often be treated with self-care including:

1. Ice the joint for 10 minutes at a time.
2. Compress the area with an ace bandage.
3. Take an over-the-counter pain medication such as Ibuprofen or Naproxen for pain or swelling.

How do you prevent TFCC?

To help prevent a TFCC tear, your physical therapist may advise you to:

1. Avoid falling on your hand.
2. Avoid repetitive, high-impact activities using the hands.
3. Use a brace or taping.
4. Gradually increase any athletic activity, rather than suddenly increasing the activity amount or intensity.

What causes TFCC pain?

TFCC tears are often painful and can affect a person’s ability to use their hand or wrist. They can result from sports injuries, overuse of the wrist, and inflammatory conditions such as rheumatoid arthritis. TFCC tears are also more common in older people.

How do you treat TFCC?

If you have persistent TFCC tears, your doctor may recommend minimally invasive surgery. The most common surgery used to treat TFCC is arthroscopy. During arthroscopy, your orthopedic surgeon will repair the damaged area through a series of incisions along the outside of the wrist.

What is sigmoid notch?

The sigmoid notch (also referred to as the trochlear groove or semilunar notch) is a cup-like depression within the proximal ulna formed from the olecranon and the coronoid process (Fig. 2), and it is covered with articular cartilage in an arc of 190 degrees when viewed sagittally.

What are the parts of the TFCC?

The TFCC consists of fi ve parts: 1. The fi brocartilaginous disk and the meniscal homologue 2. The ulnocarpal ligaments on the volar aspect (the ulno- lunate and the ulnotriquetral ligaments) (Fig. 7.2) 3. The dorsal and volar radioulnar ligaments (each with a superfi cial and deep part) (Fig. 7.3a, b) 4.

What is the morphology of the proximal portion of the TFCC?

The proximal portion of the TFCC reinforced the hammock structure which in turn supported the carpus. The morphology of the proximal portion of the TFCC was categorised as fan shape, V-shape or funnel shape in appearance [Fig 8]. (4) Its volar and dorsal margins were found to be thick and serve as stabilizing ligaments.

What is the triangular fibrocartilage complex (TFCC)?

The Triangular fibrocartilage complex (TFCC) is an incredibly complex structure that provides intrinsic stability to the distal radioulnar joint and the ulnocarpal aspect of the wrist. It is named so because of its triangular anatomic as well as its structural shape (Figure 1).

What ligaments are in the TFCC?

Anatomically the TFCC includes the triangular fibrocartilage disc, extensor carpi ulnaris tendon subsheath, ulnotriquetral and ulnolunate ligaments, dorsal and volar distal radioulnar ligaments, meniscal homolog, and the ulnocarpal collateral ligament.
