What is the TFCC composed of?

What is the TFCC composed of?

The TFCC was found to be a homogenous structure composed of but not dissectable into, the articular disc, the dorsal and volar radioulnar ligaments, the meniscus homologue, the ulnar collateral ligament, and the sheath of the extensor carpi ulnaris.

Is the TFCC a ligament or tendon?

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 is TFCC pathology?

The triangular fibrocartilage complex (TFCC) is a load-bearing structure between the lunate, triquetrum, and ulnar head. The function of the TFCC is to act as a stabilizer for the ulnar aspect of the wrist. The TFCC is at risk for either acute or chronic degenerative injury.

What is the TFCC joint?

The Triangular FibroCartilage Complex, or TFCC, is an important structure in the wrist. The TFCC is made of tough fibrous tissue and cartilage. This tissue supports the joints between the end of the forearm bones (radius and ulna), adding to their stability.

What is fibrous cartilage?

Fibrocartilage is the tough, very strong tissue found predominantly in the intervertebral disks and at the insertions of ligaments and tendons; it is similar to other fibrous tissues but contains cartilage ground substance and chondrocytes.

Where is the triangular fibrocartilage complex located?

Overview. A triangular fibrocartilage complex (TFCC) is a structure in the wrist that supports the carpal bones on the wrist. The TFCC is responsible for keeping the radius and ulna stable as the hand grasps an object or the forearm rotates. If this cartilage tears, you can experience chronic wrist pain.

What is a full thickness tear of the TFCC?

A TFCC tear is an injury to the triangular fibrocartilage complex, soft tissues in the wrist that cushion and support the carpal bones and help stabilize the forearm. Injuries range from mild to severe, but all can disable the wrist.

How do you treat TFCC pain?

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 is TFCC diagnosed?

TFCC tears are often diagnosed using the fovea test, also called the ulnar fovea sign. To do this, your doctor will apply pressure to the outside of your wrist and ask if you feel any pain or tenderness. They’ll do the same to your unaffected wrist for comparison.

Where is TFCC found?

A triangular fibrocartilage complex (TFCC) is a structure in the wrist that supports the carpal bones on the wrist.

What is the anatomy of the TFCC?

Gross anatomy. The TFCC is located on the ulnar aspect of the wrist joint between the ulna and the lunate and triquetrum of the proximal carpal row. It has an elongated triangular shape with the apex pointing at the radius 5 and consists of the triangular fibrocartilage disc proper along with 1, 2: volar components volar radioulnar ligament.

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.

What is the proximal and distal component of a TFCC?

–Proximal component – triangular ligament and ligamentum subcruentum –Distal component – distal hammock structure (meniscus homologue) and ulnar collateral ligament i. Atzei A. New trends in arthroscopic management of type 1-B TFCC injuries with DRUJ instability.

What is the difference between TFCC and triangular fibrocartilage?

The triangular fibrocartilage (TFC) in the center is differentiated from the peripheral TFCCelements, consisting of the dorsal and palmar radioulnar ligaments, the ulnolunate and ulnotriquetral ligaments, the tendon sheath of the extensor carpi ulnaris muscle, and the ulnar collateral ligament.
