Minimally Invasive Sacroiliac Joint Fusion

One of the tenets of spine surgery is that if a joint is proven to be a pain generator, a fusion of the joint will most likely alleviate pain. Sacroiliac joint pain (SIJ) is very difficult to diagnose, as it manifests as back and leg pain and the diagnosis is not made just from a single scan or a test but from history, physical examination, imaging, and confirmatory injections. Modern techniques to fuse the SIJ via a minimally invasive, percutaneous placement of implants across the joint is being evaluated to be an excellent alternative to open, classic techniques. This chapter reviews the nuances of this technique.
