Disc - Discus triangularis - TFCC

Articular disc

A cartilaginous triangular-shaped disc holds the ulnar and the radius together, it simultaneously shares a section of the radiocarpal joint and is an important shock absorber. This disc-like structure in the wrist is called an articular disc or triangular fibrocartilage disc. The disc is fixed in ligaments between the ulnar and the radius and is an important stabiliser in the wrist. In addition to injuries following a fall onto the hand, wear of the articular disc can occur. Both can lead to persistent pain, with restriction of the mobility and primarily to the turning outwards of the hand. Arthroscopy is the treatment of choice in the event of long–lasting symptoms. Prior to an operation, however, the extent of the injury must be investigated by means of an MRI to assess whether an operation is really necessary.

Arthroscopy

 

Arthroscopy of the wrist can be carried out under regional anaesthesia (plexus anaesthesia), and also general anaesthesia at the patient’s request. The operation itself does not pose a significant burden as there is no blood loss to deal with, however the patient must have the possible complications explained to them in detail (mainly injuries to the tendons and nerves).

The majority of indications for arthroscopy of the wrist involve the articular disc complex in the wrist. Additional causes are ligament injuries and loose bodies. With all these problems, there is also irritation of the joint mucosa (synovitis), which also causes pain in itself and can restrict the mobility of the joint.

 

In the case of injuries to the articular disc, it is resutured, smoothed or even partially removed, depending on the type of tear. Only the unstable part of the torn articular disc must be removed, however, the edge with the ligament attachments should always be retained.

Please note that medical indications and treatments change constantly. Sometimes these changes occur more rapidly than I am able to update on my homepage. Some information regarding dosage, prescription and compositions of medications may have changed in the meantime. Reading an internet page cannot replace visiting a doctor - it may be that during an examination and subsequent discussion with your doctor, other information is also communicated as a result of new scientific knowledge.
