Abstract

The triangular fibrocartilage complex (TFCC) is the most important stabilizer of the distal radioulnar joint (DRUJ). Its injury is the main cause for ulnar sided pain after wrist trauma. In recent years, advancements of wrist arthroscopy improved the diagnostics and treatment of the TFCC tears. The purpose of this article is to describe a variant of radial tears (1D according to Palmer), in which the radio-ulnar ligaments were ruptured in the midsubstance just before (Pre) their insertion on the sigmoid notch and illustrate the arthroscopic surgical technique used for its treatment. We name this variant of the Palmer 1D lesion, the pre-1D TFCC lesion.
