Interlaminar epidural steroid injection

In the midline interlaminar epidural steroid injection approach, the placement of the needle in the dorsal epidural space under fluoroscopic guidance is relatively easy and safe; but the spread of the injectate into the lateral and ventral epidural spaces may be minimal due to the presence of epidural ligaments/scar tissue. Hence, the clinical efficacy is limited.
