When pain occurs along the pinky side of the wrist, a tear of the triangular fibrocartilage complex (TFCC) may be one possible cause. In this article, we will explain what causes a triangular fibrocartilage complex tear, the signs and symptoms to watch for, how a TFCC tear is diagnosed, and the nonsurgical and surgical options available.

The triangular fibrocartilage complex, commonly called the triangular fibrocartilage complex TFCC, is a group of cartilage and ligaments located on the ulnar side of the wrist. It cushions the wrist bones, stabilizes the ulna bone and radius bone, and helps the wrist and forearm move properly.
A TFCC tear occurs when this tissue becomes damaged. Some tears happen suddenly, while others develop gradually. Many TFCC tears are minor TFCC tears that may respond well to conservative care, while more significant injuries can cause instability or ongoing loss of wrist function.
TFCC injuries can have several causes. An acute injury may occur after falling onto an outstretched hand, experiencing a twisting injury, or forcefully rotating the wrist. Athletic injuries are also common, particularly in sports that involve repeated gripping, swinging, or wrist rotation.
A wrist fracture can sometimes occur alongside a TFCC injury. Repetitive stress and age-related changes may also cause degenerative TFCC tears. Another contributing factor can be positive ulnar variance, in which the ulna is relatively longer than the radius and places additional stress on the TFCC. Conditions such as rheumatoid arthritis may also contribute to wrist damage over time.
The most common symptom is ulnar-sided wrist pain, or pain along the pinky side of the wrist. Symptoms may include:
Symptoms can vary depending on the location and severity of the tear. Persistent pain should be evaluated rather than ignored, particularly after an injury.
To determine whether a TFCC tear is responsible for your symptoms, an orthopedic specialist will review your medical history and perform a detailed examination. The wrist may be assessed for tenderness, stability, range of motion, and grip strength.
X-rays can help evaluate the wrist bones, alignment, and conditions such as positive ulnar variance or a previous wrist fracture. MRI may provide detailed images of soft tissue and help identify a triangular fibrocartilage complex injury. In some cases, wrist arthroscopy may be used to directly examine the joint and confirm the diagnosis.
Treatment depends on the severity and type of injury. Many minor TFCC tears can improve without surgery, particularly when treatment begins early. Initial care may include temporarily limiting activities that aggravate the wrist and using a brace or splint to support the joint.
As symptoms improve, a carefully structured rehabilitation program can help restore movement, forearm muscle strength, and grip strength. The goal is to protect the damaged tissue while gradually returning the wrist to normal use. Your orthopedic specialist can recommend the appropriate treatment based on your specific injury.
Surgery may be considered when pain continues despite nonsurgical treatment, when the TFCC tear causes significant instability, or when the injury substantially interferes with daily activities or athletic performance.
Surgical treatment may involve wrist arthroscopy, a minimally invasive technique using a small camera inserted through tiny incisions. Depending on the injury, the surgeon may remove damaged tissue, repair the TFCC, or address associated ligament problems. The goal is to relieve pain, improve stability, and restore function.
Recovery varies according to the severity of the injury and whether surgery was necessary. Following treatment, the wrist may need temporary protection while the tissue heals. Activity is gradually increased according to your orthopedic specialist’s recommendations.
Rehabilitation focuses on restoring wrist motion, strength, stability, and wrist function. Returning to sports, heavy lifting, or repetitive wrist activities too quickly can increase the risk of further injury. Following your individualized recovery plan can support a safe return to normal activities.
Although not every TFCC tear can be prevented, several habits can reduce unnecessary stress on the wrist. Use proper technique during athletic activities, avoid repeatedly forcing the wrist into extreme positions, and allow adequate recovery after strenuous activity. Strengthening the forearm muscles and maintaining good wrist mobility can also support wrist stability.
If wrist pain develops after an injury, early evaluation can help identify the problem before symptoms become more difficult to manage.
If you have persistent ulnar wrist pain, weakness, clicking, or instability, Georgia Hand, Shoulder & Elbow provides specialized orthopedic care for conditions affecting the hands, shoulders, and elbows. Schedule an appointment at our office in Marietta or Atlanta, GA, to have your wrist evaluated and learn which treatment options may be right for you.
