The triangular fibrocartilage complex (TFCC) is located in the wrist between the ulnar bone end and the carpals. It is a complex structure and is a major function is stabilising, cushioning and smooth movement at the radioulnar joint of the wrist. It has an extended triangular shape and consists of –- The triangular fibrocartilage disc.
- Ulna meniscus.
- Ulnar collateral ligament.
- Several carpal ligaments.
- Extensor carpi ulnaris (ECU) tendon sheath.
You can tear your triangular fibrocartilage complex TFCC from various activities like playing sports, fall with an extended arm etc. The TFCC tear can cause pain in the wrist. Other symptoms of this injury include pain on the side of the pinky finger, tenderness on the wrist back. You will experience extreme pain if you bend your wrist sideways. You will also suffer from swelling in the wrist and loss gripping strength.
In most of TFCC injury, traditional treatment works wonders. This treatment involves adding a splint to your wrist for approximately 4 weeks. After this period a removable splint is added allowing you to move your wrist slowly. Other treatments include anti-inflammatory medication, electrotherapy, mobility and strengthening exercises.
Another problem that your wrist may suffer is the Kienbock's disease. It is also known as avascular necrosis of the lunate, occurs when the lunate bone in the wrist is damaged due to loss of blood supply. It is a rare and incapacitating disease that can lead to chronic pain and dysfunction. An Australian radiologist Robert Kienböck first mentioned the disorder and thus it got its name after him.
The National Institutes of Health stated that affected will at first have the feeling of sprain in their wrist. It is progressive disease and hence its symptoms do not fade ways easily. However, the progress of Kienbock's disease is different from patient-to-patient. Initially, the patient suffers from swelling and pain but later the entire mechanism of the wrist is affected.
