Described by Palmer in 1984 (1), lesions of the triangular fibrocartilage complex (TFCC) affect 27% of the population under 30 years of age. They are the ligament injury that is most frequently associated with fractures of the distal radius, with a frequency ranging from 49% to 78%, depending on the study (2, 3). A TFCC detachment can lead to instability of the distal radioulnar joint, resulting in pain in the extensor carpi ulnaris and problems with daily function. A number of biomechanical studies have confirmed the crucial importance of the TFCC in stabilizing the ulnar carpus and the distal radioulnar joint. Over the course of the last two decades, several anatomical and biomechanical studies have attempted to describe this entity and its function (4, 5). Nakamura et al (4) were the first team to describe the three-dimensional structure of the TFCC, thereby resolving the paradox of the dynamic changes of this ligament in pronation and supination (6). The development of arthroscopy has played a large part in our greater understanding of TFCC injuries and has enabled such injuries to be classified into different types. Thus, in partnership with EWAS (European Wrist Arthroscopy Society), Dr Andréa Atzei (7) introduced a classification of peripheral TFCC...
