Triangular fibrocartilage complex disorder is a lesion of the anatomical structure called the articular disc and adjacent ligaments connecting the radioulnar and ulnocarpal joints. These structures are included in wrist movements, cushioning, and stabilization of the joints.
Triangular fibrocartilage complex (TFCC) disorder is distinguished by symptoms of pain on the ulnar side of the wrist, uncomfortable rotation of the wrist, or strain during movements against resistance. These clinical clues propose a possibility of injury in the TFCC. This is most commonly caused by events of mechanical trauma, degenerative processes, and ulnocarpal impaction  .
Chronic overburdening of the radioulnar and ulnocarpal joints may be the reason for impaired blood supply which results in a degeneration of the joint structures. Subsequently, restriction of mobility, pain, and weakness of wrist is noted . Patients usually complain of inefficiency when performing basic tasks, affecting their lifestyle and ability to work .
Physical examination is useful in identifying the severity of TFCC damage. A wrist ulnar stress test comprises the act of a physician which apply an axial force on the radioulnar and ulnocarpal joints, perform rotatory movements, and observe the patients for symptoms and signs of pain or discomfort. If the pain is recognized, the wrist ulnar stress test is regarded as positive and further investigations should be performed. The palpation of the inner part of the affected wrist will reveal tenderness associated with triangular fibrocartilage complex disorder  .

It occurs most often in those who fall on an outstretched hand. Athletes are at risk, especially those who use a racquet, bat or club and those who put a lot of pressure on the wrist such as gymnasts. [rushortho.com]
Causes of triangular fibrocartilage complex (TFCC) tears or sprains There are many causes of triangular fibrocartilage complex (TFCC) tears or sprains including: Falls — triangular fibrocartilage complex (TFCC) tears can occur if someone falls on their [mercy.com]
For example, if someone was to fall on an outstretched hand, damage to cartilage, tendons or ligaments may occur. Type 2 tears are caused by a slow breakdown of the cartilage in the TFCC. [mcboh.com]

Just as importantly, the wrist must be strong and stable, so that when we grasp an object, the joint does not collapse or flop around. The TFCC has a hard job. The TFCC is formed as a ring of cartilage, much like the meniscus of the knee. [verywellhealth.com]
The most common finding is amorphous calcifications within the triangular fibrocartilage complex (TFCC) of the wrist, radiocarpal narrowing and in advanced cases scapholunate advanced collapse. [cedars-sinai.edu]

Two patients developed reflex sympathetic dystrophy, and one patient had a localized wound infection through the skin because of the PDS suture knot. A 0-Vicryl suture is now used for all repairs. [healio.com]
Although rehab therapy has shifted away from prolonged immobilization, even for many fractures, there is a “Tea Party” faction in every group. [rockandice.com]
An x-ray will rule out fractures and dislocation, while also providing information on potential wrist instability. When there is concern for a complete tear, an MRI will allow visualization of the TFCC. [handsport.us]
A clicking sensation may be appreciated by the examiner on range of motion and depression or sag of the carpals on the ulnar side of the unsup- ported wrist. [pocayo.com]

Triangular fibrocartilage complex disorder is diagnosed by clinical examination and different imaging modalities . After the imaging findings give ground for the diagnosis of TFCC disorder, an arthroscopy with an evacuation of injured tissues and the treatment of affected ligaments is performed . An arthroscopy provides an opportunity to examine the joint in situ, rendering it the most valued method of examination and the main method in a making of a final diagnosis . Abnormalities such as ligament injuries, cartilage lesions, TFCC disconnection, degenerative tears, as well as a proliferation of the synovium, can be distinguished  .
Imaging studies include computer tomography (CT) and magnetic resonance imaging (MRI). CT could reveal displacements of the bones involved in the ulnocarpal and radioulnar joints which commonly accompany TFCC disorder. Axial plane is used for such purposes .
MRI examination in a coronal plane is advantageous when investigating specific areas and the intricate anatomy of the injured TFCC. An exclusion is a dorsal tear, which is better observed in sagittal and axial planes . High-resolution 3T MRI modality is favored if a suspicion of TFCC disorder arises . Although magnetic resonance imaging is a very useful procedure, it can be difficult for specialists to determine the correct diagnosis based exclusively on the imaging findings. Misdiagnosed TFCC disorder may lead to serious problems, thus appropriate diagnosis confirmed by arthroscopy is of immense importance .
