Abstract
Clinical assessment of distal radioulnar joint (DRUJ) instability has been shown to be unreliable among experienced hand surgeons in the United Kingdom (UK). The aim of this study was to test the reliability of assessing DRUJ stability in European surgeons outside the UK. Four participants (eight wrists) with four unstable and four stable DRUJs as measured with a proven jig were assessed by 34 surgeons (22 men and 12 women) with a mean age of 43 years (range 29–61). Clinical assessment of DRUJ instability had a sensitivity of 32%, specificity of 88%, a positive predictive value of 72% and a negative predictive value of 56%. Surgeons who had attended a 1-hour workshop on clinical assessment of DRUJ stability the day before the testing were no more reliable at assessing DRUJ instability when compared with those who did not. This further highlights the need for better training with feedback when assessing the DRUJ and the need for objective assessment of DRUJ instability when reported in scientific studies.
