This article describes an innovative technique for effective analgesia and enhanced accuracy in placement of percutaneous sacroiliac screws in patients with unstable, posterior pelvic ring injuries. Our approach involves introducing radio-opaque contrast through an indwelling caudal epidural catheter to enhance existing computer navigation systems. This delineates the lumbosacral nerve roots to promote the safe and accurate placement of sacroiliac screws and concurrently provides effective analgesia. We describe the technique and our first cases. It can be used to supplement your current technique in placing sacroiliac joint screws and provide effective analgesia for our patients.
