TFCC tears are often diagnosed using the fovea test, also called the ulnar fovea sign. To do this, your doctor will apply pressure to the outside of your wrist and ask if you feel any pain or tenderness. They’ll do the same to your unaffected wrist for comparison. You may also be asked to do a variety of wrist movements.
How can you tell if a TFCC is torn?
What are the symptoms of a TFCC tear?Sounds, like clicks or pops, when you rotate your wrist or forearm.Difficulty rotating your wrist.Pain on the ulnar side of your wrist (outside, near the pinky finger).Reduced ability to grip objects tightly.Wrist weakness.
What does TFCC load test?
The TFCC load test begins with the wrist in ulnar deviation. A longitudinal load is then applied through the 4th and 5th rays to the TFCC. A positive test is pain at the TFCC. One should remember, this position is similar to the clamp test for the scaphoid.
Can TFCC tear be seen on xray?
X-ray arthrography presented with a pooled sensitivity of 76.2% and specificity of 92.5% for the detection of complete TFCC tear.
Will an MRI show TFCC tear?
Standard MRI can achieve high performance in detection of the TFCC tear. In a recent study, Zlatkin et al. found that the sensitivity, specificity and accuracy was 92%, 89% and 91% respectively (4).

What percentage of TFCC tears require surgery?
Among the patients with clinical diagnosis of triangular fibrocartilage complex injury, the rate of surgical intervention required after a minimum 4 weeks of immobilization was 43%.
What happens if a TFCC tear goes untreated?
The TFCC is what keeps the bones in the forearms, called the radius and ulna, from pulling apart. It works like a shock absorber for the joints on your hands, therefore, a tear, lesion or injury in the TFCC may cause acute wrist pain. If left untreated the pain may become chronic.
Can TFCC tear heal without surgery?
The quick answer to this question is yes, a TFCC tear can heal without surgery. It's important to understand that the area toward the outside of the wrist will heal better without surgery, and it may take some time for your pain to improve.
Is TFCC tear serious?
A TFCC tear is an injury to the triangular fibrocartilage complex, soft tissues in the wrist that cushion and support the carpal bones and help stabilize the forearm. Injuries range from mild to severe, but all can disable the wrist.
How long do TFCC tears take to heal?
Recovery time for TFCC tears that do not require surgery is generally four to six weeks. If surgery is required, it might take anywhere from six weeks to several months to restore full wrist function. Physical therapy and avoiding activities that put a pressure on your wrist might help you heal faster.
What should you avoid with a TFCC tear?
If you have a chronic TFCC tear, you'll need to take continuous care of your wrist. The best thing you can do is avoid a lot of repeated wrist movements. You can also modify motions that are typically painful.
Are TFCC tears painful?
TFCC tears are often painful and can affect a person's ability to use their hand or wrist. They can result from sports injuries, overuse of the wrist, and inflammatory conditions such as rheumatoid arthritis. TFCC tears are also more common in older people.
How do you test DRUJ instability?
DRUJ stress test or ballottement test: The radiocarpal joint is stabilized with one hand while the ulna is shucked with another hand against the radius. The test is positive if it is aching and severely unstable in symptomatic individuals. The test has a specificity of 96% but solely a sensitivity of 59% (31).
What is the TFCC in the wrist?
The triangular fibrocartilage complex consists of the triangular fibrocartilage disc, ulna meniscus, ulnar collateral ligament, carpal ligaments and the extensor carpi ulnaris tendon sheath. Its function is to provide stability, cushioning and smooth movement in the wrist joint.
What is a full thickness tear of TFCC?
A TFCC tear is an injury to the triangular fibrocartilage complex, soft tissues in the wrist that cushion and support the carpal bones and help stabilize the forearm. Injuries range from mild to severe, but all can disable the wrist.
Can you lift weights with TFCC tear?
In all cases, during the initial inflammatory period rest (so no training, lifting or gymnastics), ice and immobilization are the recommended protocols. The best position for the injured wrist is in a neutral position (see left) and supported by a brace.

What customers have to say about the Assessment E-Book
The Assessment E-Book The book is fantastic. A great acquisition for all professionals because it presents all information in a concise, clear and grouped way.
How to perform a TFCC stress test?
The TFCC compression test is performed by ulnar deviating the forearm in neutral rotation. Reproduction of symptoms indicates that the test is positive In the TFCC stress test an axial load is applied to a ulnar-deviated wrist which produces pain and discomfort. The piano key test is done to assess the stability of the DRUJ. It is done in pronated position of forearm. With the hand being stabilized, the dorsal ulnar prominence relative to radius is observed and the ulnar head in pushed volarly. A positive piano key sign is noted when minimal amount of resistance is felt againt volar displacement of ulnar head, suggesting the presence of underlying DRUJ instability. The test should be repeated with the forearm in supination. Comparision of the amount of ulnar displacement must be done with contralateral side because patients with generalized ligamentous laxity may have a substantial amount of abnormal baseline displacement.
What is the TFCC?
The triangular fibrocartilage complex (TFCC) is a well defined anatomical entity located on the ulnar aspect of the wrist joint functioning primarily to stabilize the distal radio –ulnar joint (DRUJ) and also to act as a shock absorber across the ulno-carpal joint.
What is the best test to assess DRUJ laxity?
Another simple and reliable test to assess DRUJ laxity is the ballottement test.7This test involves antero-posterior and postero-anterior translation of the ulna on the radius passively in a neutrally rotated forearm. Abnormal translation of the ulnar head suggests a complete TFCC disruption. While repeating the test in full supination, comptence of dorsal component of DRUJ ligaments, and in pronation, of the volar components can be tested separately.
What causes TFCC to be damaged?
The other common cause of injury of the TFCC is the disruption of normal ulnar variance, most likely secondary to previous trauma, which renders the distal ulna to be longer than articular margin of the lunate fossa of the radius at the wrist. This positive variance has been shown to make the TFCC susceptible to injury and degeneration as a result of ulno-carpal impingement.
Where to palpate TFCC?
The best place to palpate the TFCC is the soft spot on the volar aspect of wrist distal to ulnar head between the ulnar styloid, FCU and pisiform. Tay et al.6described the “ulna fovea sign” which is positive when pain is elicited on plapation of this critical area labelled as fovea. When positive, it is a reliable test to diagnose tear of the ulno-triquetral ligament tear or disruption of the foveal attachment of the TFCC. This test has high sensitivity of 95.2% and a specificity of 86.5%.
How to perform a grind test?
The Grind test is performed by compressing the distal forearm and having the patient pronate and supinate. Presence of pain suggests DRUJ arthritis.
Is TFCC avascular or avascular?
They found that the disc is vascular on its periphery only, otherwise it is largely avascular. It is composed of fibrocartiagenous tissue. The ulnotriquetral, ulnolunate ligaments and the ECU subsheath are composed of loose as well as tightly packed, parallely oriented bundles of collagen fibers. The ligaments connecting the distal radius to ulna on volar and dorsal aspect are strong and contain tightly packet bundles of collagen and are important stabilizers of the distal radio-ulnar joint. The meniscal homolog is composed of loose connective tissue.
What is TFCC in a patient?
In patients whose ulna is longer than the radius at the wrist, the TFCC is usually thinner and more likely to tear.
What to do if TFCC doesn't help?
If these don’t help, there may be surgical treatments available. Possible surgical treatments are varied depending on the specific, underlying TFCC injury. Visit a hand surgeon to discuss your specific symptoms and work out a treatment plan.
What is the first type of TFCC tear?
The first type of TFCC tear is due to natural wear , and the other is usually from injury. Tears due to wear are the most common and are usually not seen in younger people. They become more common as one gets older. Tears from injury can come from: A fall on the hand or wrist.
Can a TFCC tear cause pain?
For some, a TFCC tear may not cause any pain or instability problems in a wrist . Often, MRI studies show tears in people with no pain or problems using the wrist. Others may experience some or all of the following symptoms: Clicking or popping while turning the forearm or moving the wrist from side to side. Pain.
Can a TFCC tear cause ulnar sided pain?
It can be difficult to find the cause of ulnar-sided wrist pain in the area of the TFCC since there are other conditions in this area that can cause similar problems. A hand surgeon may use special wrist examination methods to diagnose a TFCC tear.
What is TFCC in wrist?
TFCC stands for triangular fibrocartilage complex. It contains a dense cartilage on the ulnar side of the wrist and binds the radius to the ulna (Morrison, 2019).
What is a type 2 TFCC?
Type 2 TFCC injury is considered degenerative and chronic where the cartilage wears down over time. TFCC injuries may be seen in inflammatory disorders such as gout and rheumatoid arthritis as well (Morrison, 2019). Tears can be located in the ulnar or central portion of the ligament.
How long does it take for a TFCC to heal?
If the TFCC injury is recent, hand therapists may create a muenster splint to limit supination and pronation or wrist mobility while the TFCC injury heals for the first 6-8 weeks (Barlow, 2016).
What are the two types of TFCC tears?
There are two types of TFCC tears. Type 1 is caused by excessive wrist movements. Examples of this include gymnasts who continually land on extended wrists, construction workers using high velocity tools like a drill or jackhammer, or an individual falling on an outstretched hand (Atzei & Luchetti, 2011). Type 2 TFCC injury is considered degenerative and chronic where the cartilage wears down over time. TFCC injuries may be seen in inflammatory disorders such as gout and rheumatoid arthritis as well (Morrison, 2019).
What is the last proactive test?
The last proactive test is called the “pressed” test. The client sits on a chair with hands grasping the edges of chair. The client is directed to weight bear on extended wrists as they push themselves up off of the chair. If pain in ulnar region occurs, the test is considered positive.
Can X-rays detect soft tissue?
An X-ray is unable to detect soft tissue but may provide insight with fractures and abnormalities within the wrist and may correlate with a TFCC injury.
Can a TFCC tear occur from an outstretched fall?
Individuals with repetitive trauma from work or leisure activities may also acquire wrist pain. A TFCC tear may also occur unintentionally from an outstretched fall ...
How to test for TFCC?
Piano key test: Place both hands on an exam table and press the palms on the table. If the distal ulna is prominent on the affected side, this suggests distal radioulnar joint instability which can have associations with TFCC injury. If the palms are relaxed and the ulnar head goes back to normal position, this is a positive test
What is the function of TFCC?
The function of the TFCC is to act as a stabilizer for the ulnar aspect of the wrist. The TFCC is at risk for either acute or chronic degenerative injury. Forced ulnar deviation and positive ulnar variation carry associations with injuries to the TFCC.
What is the best treatment for TFCC?
MRI imaging is useful as a preliminary diagnostic tool; arthroscopy is the diagnostic gold standard. Treatment options include conservative therapies such as rest, NSAIDs, and corticosteroid injections as well as operative management. Prognosis for TFCC injury is generally favorable.
Where is the TFCC palpation?
On exam, palpation of the TFCC is best with the wrist in pronation. It is between the flexor carpi ulnaris, ulnar styloid, and os pisiform. Several physical exam tests can suggest the diagnosis of TFCC injury. These include:
Can TFCC be injured?
In gymnastics the TFCC can be injured through overuse injury (both support skills and hanging elements). With repetitive weight bearing (both compressive and tensile), this area can become inflamed and tendonitis /tendonosis can develop in the anchoring wrist ligaments (often misdiagnosed as a wrist sprain).
Can ulnar variation leave the TFCC vulnerable to injury?
Positive ulnar variation can leave the TFCC vulnerable to injury.
