Differentiated Approaches to Treat Lesions of the TFCC Based on new arthroscopic Classification

Abstract

AbstractIn this article, pathology of the TFCC lesions, image diagnosis and arthroscopic examination were described. According to the radiocarpal arthroscopic findings, TFCC lesions are classified into intra-disc lesions (Class 1), radial lesion (Class 2), peripheral disc lesions which indicate slight to moderate DRUJ instability (Class 3) and degenerative lesion (Class 4). The radioulnar ligament (RUL) lesions that indicate moderate to severe DRUJ instability were classified with staging system with DRUJ arthroscopic findings (Stage 1 to 5). Author’s treatment algorism with wrist arthroscopic findings including DRUJ arthroscopy was demonstrated and along with this algorism, various arthroscopic and open techniques to treat TFCC injuries were selected and resulted in success. Precise diagnosis of the TFCC lesions helped to select an adequate treatment for each lesion.
