Damage to the TFCC occurs when patients break their fall with their hands. These accidents often occur when swinging a baseball bat or hitting a backhanded badminton stroke with considerable torque applied to the wrist area as well. Most injuries are caused by sudden trauma, and once TFCC becomes an issue, it often becomes a chronic condition. TFCC patients suffer from a dull pain in the ulnar area, which becomes more severe when the wrist is bent or twisted. In severe cases, patients may not be able to push themselves off the ground with their hands or push a revolving door due to severe pain.
Also, patients may experience severe pain when they are required to flick their wrist.

Patients suffer from tenderness and pain when pressing the ruptured area or when turning the wrist.
MRI is the most popular way to diagnose TFCC. Recently, hospitals are using MRAs with contrasting agents to improve the accuracy of their diagnoses. The most accurate method, however, is an arthroscopic diagnosis.

During the early stages of an acute rupture, the injured area is often immobilized with a cast. If, however, pain persists or the tear becomes more extensive, surgical repair may be required.
For severe or degenerative ruptures, a debridement procedure may be performed followed by a repair of the frayed edges.
