Sacroiliac joint (SIJ) injections are valuable tools for diagnosing the source of low back pain and selecting patients for a radiofrequency ablation procedure, which tends to provide long-term relief for low back pain associated with SIJ dysfunction. Sacroiliac joint injections are generally safe and well-tolerated procedures. The most common complication is initial pain from distension of the joint capsule with contrast and local anesthetic. Despite adequate intra-articular needle placement, extravasation of local anesthetic may diffuse to lumbosacral nerve roots and/or the sciatic nerve, causing transient numbness and/or weakness. This chapter reviews the advantages of fluoroscopically guided SIJ injections as well as the step-by-step technique and how to avoid complications.
