TFCC tear
Pronunciation: T-F-C-C
Injury to the triangular fibrocartilage complex of the wrist, commonly affecting athletes in racquet sports.
Full Definition
TFCC tear refers to an injury of the triangular fibrocartilage complex, a structure located on the ulnar (pinky) side of the wrist that provides stability and cushioning between the ulna bone and the carpal bones. The TFCC consists of fibrocartilage, ligaments, and a meniscus-like disc that acts as a shock absorber during wrist rotation and ulnar deviation. These tears are commonly seen in athletes participating in racquet sports, gymnastics, or activities requiring repetitive wrist rotation and loading. Athletes typically present with ulnar-sided wrist pain that worsens with gripping, twisting motions, or weight-bearing on the hands. The pain may be accompanied by clicking or instability symptoms. Diagnosis often requires MRI arthrography, and treatment may range from conservative management to arthroscopic repair.
Usage
Usage note: Acronym should be spelled out as TFCC, not pronounced as word; specific to ulnar-sided wrist pathology.
