Overview
A TFCC tear is an injury to the triangular fibrocartilage complex, a group of tissues on the ulnar (pinky side) of the wrist that helps cushion the joint and stabilize the distal radioulnar joint (DRUJ). When the TFCC is torn, the wrist may become painful during gripping, twisting, or loading, and the DRUJ can feel unstable. Tears can happen suddenly after trauma or gradually from repetitive stress and degeneration. Pain is often localized on the ulnar side of the wrist and may worsen with rotation of the forearm.
Symptoms
Patients commonly notice sharp or aching ulnar-sided wrist pain, especially with twisting motions like opening jars or turning a key. Gripping, push-ups, or lifting with the wrist may feel weak or uncomfortable, and some people report clicking, popping, or a sense of catching. Swelling can occur after a new injury, while chronic tears may cause persistent soreness. Forearm rotation and wrist extension may aggravate symptoms, and some patients feel tenderness when pressing the ulnar fovea area near the wrist crease.
Causes
TFCC tears can result from a fall onto an outstretched hand, a direct blow to the wrist, or forceful twisting that injures the tissue. In other cases, wear-and-tear degeneration weakens the TFCC over time, making it more vulnerable to small repeated stresses. DRUJ instability, abnormal ulnar variance, or associated wrist injuries can also contribute to TFCC damage.
Risk Factors
Risk is higher in people who participate in activities with repetitive wrist loading or rotational stress, such as racquet sports, weight training, or manual labor. Acute risk increases after wrist trauma, especially falls with the hand extended or sudden rotational forces. Degenerative changes with age, prior wrist injuries, and anatomic variations such as ulnar positive variance can make tears more likely.
Prevention
To reduce risk, use proper technique and avoid sudden increases in repetitive wrist loading, allowing gradual conditioning when starting or returning to sports or work. A neutral wrist position during lifting and minimizing extreme twisting can help protect the TFCC and DRUJ. Forearm and wrist strengthening with guidance from a clinician or therapist can improve joint control, and supporting the wrist with a brace during higher-risk activities may reduce strain.
How the Diagnosis Is Evaluated
Clinicians usually start with a detailed history of how the injury occurred and what movements reliably reproduce pain. A focused physical exam assesses ulnar-sided tenderness, wrist range of motion, grip-related pain, and DRUJ stability using maneuvers such as ulnar fovea tenderness and TFCC-specific tests. X-rays are commonly obtained to rule out fractures, arthritis, or ulnar variance and do not directly show the TFCC tear in many cases. MRI or MR arthrogram may be used to confirm the tear and evaluate associated ligament or joint injury when symptoms persist or when the diagnosis is unclear.
Nonsurgical Treatment Options
Treatment focuses on reducing stress to allow symptom improvement and tissue healing or stabilization. Many patients benefit from short-term wrist immobilization with a splint or brace that limits forearm rotation, along with activity modification to avoid twisting, heavy gripping, and painful extension. Hand therapy can restore range of motion and strengthen supporting muscles while teaching movement strategies to reduce ulnar-side loading. Over-the-counter or prescribed anti-inflammatory pain control may help manage flare-ups. Corticosteroid injections may be considered for persistent pain after conservative measures, and platelet rich plasma (PRP) injections may be considered in some cases as an adjunct, depending on local practice and patient factors.
When to Seek Medical Attention
Seek prompt medical attention if you have a recent injury with significant pain, marked swelling, deformity, or you cannot comfortably use the hand or grip. Get evaluated urgently if there is sudden loss of wrist function, rapidly worsening pain, or a feeling that the wrist or forearm is unstable or "shifting." Fever, redness spreading across the wrist, or severe pain out of proportion to the injury should be assessed urgently. Seek care sooner if symptoms persist beyond a couple of weeks despite rest and bracing, or if clicking, catching, or weakness continues to interfere with daily activities.
Frequently Asked Questions
TFCC tears usually cause ulnar-sided wrist pain that worsens with twisting, gripping, push-ups, or turning the forearm, sometimes with clicking or popping.
Not always; clinicians often diagnose based on history and exam findings, and imaging like MRI or MR arthrogram is used when the diagnosis is uncertain or symptoms do not improve.
Corticosteroid injections can reduce pain for some people, and PRP may be considered in select cases, usually after initial conservative treatment.
Next Steps
If your symptoms match ulnar-sided wrist pain that worsens with twisting or gripping, arrange an evaluation with an orthopedic or sports medicine clinician or a hand specialist. In the meantime, reduce twisting and heavy loading, consider a supportive wrist brace or splint, and monitor whether pain improves with rest. If pain is severe after a recent injury or you feel unstable shifting, seek care sooner rather than waiting.
