PY - 2015 T2 - Atlas of Pain Medicine Procedures AB - The sacroiliac joint (SIJ) is the largest axial joint in the body with an abundance of nociceptive pain fibers within the joint and surrounding ligaments. SIJ dysfunction or syndrome is pain originating in the sacroiliac joint without demonstrable anatomic lesion and is presumed to be due to a biochemical abnormality.1 Predisposing factors include conditions causing stress on the joint such as spinal deformity, previous spinal surgery, and leg length discrepancy. Symptoms of SI joint dysfunction include pain in the superior medial quadrant of the buttock, the lateral buttock, and inferior to the posterosuperior iliac spine, with radiation to the greater trochanter, upper lateral thigh, and groin (Figure 26-1).
