Triangular Fibrocartilage Complex Injury
Description
The triangular fibrocartilage complex (TFCC) in the wrist consists of cartilage and ligaments and is located on the side of the wrist closest to the body (ulnar side). The TFCC helps the wrist to move normally and stabilizes the bones of the wrist. An injury, usually from a fall, can occur to the TFCC resulting in an over stretching of the ligament or cartilage (sprain), or a tear of these structures. Some injuries to the TFCC can result in persistent pain and swelling (chronic injury).
Symptoms
With the palm facing forward the side of the wrist closest to the body is called the ulnar side. Pain and clicking is experienced in this area. Other associated symptoms may be swelling, decreased wrist movement (range of motion / ROM) and decreased strength.
Tests
A history and physical exam will be performed. A Xray may be done to rule out a bony injury. An MRI with our without contrast is needed to identify specific ligament and cartilage injury to determine the severity of the damage.

Treatment
Therapy depends on the symptoms and the extent of damage. Treatment includes rest, ice, compression, and elevation (RICE). Some patients may also benefit from immobilization with a splint or cast. If symptoms persist other treatment options include physical therapy, cortisone injection, or surgery.
