The sacroiliac joint complex (SIJC) is composed of complex anatomy of numerous potential pain generators that demonstrate varying pathophysiology and differing innervations. This heterogeneity has been a challenge to advancing research and clinical care. Moving forward, individualized approaches taking these factors into account may be a path forward to improved outcomes. Thus, as we move toward precision medicine in interventional spine care, it is imperative to investigate more targeted diagnostic and therapeutic approaches to the SIJC.
