The triangular fibrocartilage complex (TFCC) is a structure of cartilage and ligaments on the pinky (ulnar) side of the wrist. It cushions and stabilizes the small carpal bones during gripping and rotating movements. A TFCC tear can result from trauma (falls on an outstretched hand, sudden twisting) or from degenerative wear over time, causing ulnar-sided wrist pain and instability.
TFCC injuries are common in athletes who grip and rotate—tennis players, golfers, and gymnasts—as well as anyone who falls onto an outstretched hand. At Mountain Spine & Orthopedics, our hand and wrist specialists use advanced MRI imaging and clinical examination to diagnose TFCC tears and determine the optimal treatment approach.
