The prevalence of sacroiliac Joint (SIJ) disease as a cause of LBP is considered to range from 21% to 25%. Nevertheless, SIJ instability is frequently underestimated. Although conventional surgery has been used for several years in an attempt to stabilize the SIJ, a new percutaneous system has been proposed for articular fusion. Recently a new “one-step” fixation procedure has been proposed. We describe the case of a patient with painful SIJ instability treated with a fully CT-guided technique in simple analogue sedation.
