Abstract
Triangular fibrocartilage complex (TFCC) injury is generated with high frequency in a sports activities requiring a grip. In this paper, we explain the function of TFCC, conditions of TFCC injury, features of the grip and physical therapy for stabilizing the wrist joint. TFCC has three functions. These functions are to maintain the stability of the distal radioulnar joint, to provide support at the ulnar side of the wrist joint, and the transmission of power through wrist joint. The features of TFCC injuries are swelling and pain in TFCC surroundings. Moreover, an instability of distal radioulnar joint was occured in TFCC injury. The wrist joint might become unstable because of this phenomenon. In the physical therapy for TFCC injury, the improvement of grip skill is important. It involves stretching for the palmar intercarpal ligaments, flexor retinaculum and adductor pollicis muscle and mobilization of the carpal joints as well as grip exercise.
