In this study, ultrasound had a sensitivity of 29% and specificity of 90% compared with the herniography. Correlation with surgical findings showed ultrasound to have a sensitivity of 33% and a specificity of 100%.
I'm not surprised about the ultrasound results. I can't comment on the herniography part, since I've only ever done one (many years ago), but maybe I'll need to start practising.
