[Arthroscopic stabilization of the distal radioulnar joint and treatment of TFCC lesions].

Arthroscopic treatment of TFCC lesions and stabilization of the DRUJ offer a differentiated range of findings-oriented procedures. Theses include central smoothing/partial resection via peripheral capsular sutures to foveal refixation and, in cases of irrepairable damage, anatomical reconstruction of the DRUJ-stabilizing radioulnar ligaments. The Palmer and Atzei classifications are widely used in everyday clinical practice and offer a structured approach to diagnosis and indication, with foveal integrity being the central criterion for DRUJ stability. Medical history, clinical examination, imaging and, in particular, diagnostic arthroscopy ensure precise classification, while standardized follow-up treatment concepts and realistic expectations ensure functional results. The choice of the specific procedure should be injury-specific, patient-related and experience-based.
