This study describes a new technique that can be used for reconstructing the triangular fibrocartilage complex to correct the static palmar radius instability of the distal radioulnar joint. In the abovementioned condition, the radius is extremely unstable with respect to the ulna and dislocates palmarly in the resting position. Using a palmar approach, a palmaris longus tendon graft was sutured to the remnant of the disrupted palmar radioulnar and ulnocarpal ligaments and then anchored to the bone tunnel that was created at the ulnar fovea. This technique predominantly reinforces the palmar structure of triangular fibrocartilage complex because the palmar radioulnar ligament is the most critical stabilizer of palmar radius instability.
