What does the dorsal radioulnar ligament do?
The radioulnar ligaments (dorsal and volar) are the primary stabilizers of the DRUJ. The secondary stabilizers include the ECU subsheath, the UL and ulnotriquetral (UT) ligaments, the lunotriquetral interosseous ligament (LTIOL). The distal interosseous ligament also plays a role in stabilizing the DRUJ.
Where is the dorsal radioulnar ligament?
The dorsal radioulnar ligament (posterior radioulnar ligament) extends between corresponding surfaces on the dorsal aspect of the distal radioulnar articulation.
What is a DRUJ injury?
Distal radioulnar joint (DRUJ) injuries can occur separately or in conjunction with distal radius fractures and both-bone forearm fractures. In fact, nearly 60 percent of forearm fractures adversely affect the DRUJ.
What is dorsal subluxation?
The cause for dorsal subluxation is extreme pronation and extension, with a strengthened extensor carpi ulnaris and ulnar carpal ligaments, which pull the ulnar head out through the dorsal capsule. Triangular fibrocartilage complex avulsion and weaking of the palmar radioulnar ligament will allow this dislocation.
How do you treat a TFCC injury?
TFCC can often be treated with self-care including:
- Ice the joint for 10 minutes at a time.
- Compress the area with an ace bandage.
- Take an over-the-counter pain medication such as Ibuprofen or Naproxen for pain or swelling.
How long does a TFCC injury take to heal?
TFCC tears that do not require surgery can take as long as 12 weeks to heal. If you have surgery to repair the TFCC, your doctor will prescribe a brace to keep the wrist immobilized for up to six weeks after surgery. A TFCC tear can take as long as three months to heal after surgery.
Will TFCC injury heal on its own?
In many cases, a TFCC tear will heal on its own. However, a person will need to avoid using the affected wrist to prevent further injury and to allow it to heal properly. A healthcare professional may also recommend wearing a splint, brace, or cast to protect and immobilize the wrist.
