AbstractThe diagnosis of chronic wrist pain is challenging and wrist arthroscopy has been recognised as the "gold standard". The present study investigated the efficacy of adding distal radioulnar joint (DRUJ) arthroscopy to routine wrist arthroscopy. The records of 67 patients who underwent DRUJ arthroscopy were reviewed, and the success rates for visualisation of intra-articular structures were determined. Pathological findings were correlated with ulnar-side wrist pain. In seven patients, pre-operative diagnoses were altered after DRUJ arthroscopy. The ulnar head and proximal surface of the triangular fibrocartilage complex (TFCC) were visualised in 100% and 99% of patients, respectively, while the foveal insertion of TFCC and sigmoid notch were visualised in 57% and 69%, respectively. Pathological findings of the proximal surface of TFCC tended to relate to ulnar wrist pain (p = 0.06). DRUJ arthroscopy should be included in routine wrist arthroscopy to enhance the accuracy of diagnosis.
