Sacroiliac Joint Interventions.

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.

Image and Contrast Flow Pattern Interpretation for Attempted Epidural Steroid Injections.

Fluoroscopically guided, contrast-enhanced epidural steroid injections (ESIs) are frequently performed for radicular symptoms. Interventionalists performing these procedures should have a thorough and detailed understanding of spinal anatomy to safely and effectively deliver the desired injectate to the targeted site. Being able to differentiate epidural from nonepidural contrast flow is vital as is recognizing flow to undesired locations. This article summarizes the characteristics that distinguish between ideal epidural flow patterns and nonideal subarachnoid, intradural, and other suboptimal contrast flow patterns. Recognizing these patterns is essential for safe and successful ESIs and to prevent avoidable complications.
