Descriptive Cadaveric Study Comparing the Accuracy of Ultrasound versus Fluoroscopic Guidance for First Sacral Transforaminal Injections

Ultrasound is rarely used for guiding lumbosacral epidural steroid injections due to its technical limitations. For example, sonographic imaging lacks the ability to confirm epidural spread and identify vascular uptake. The perceived risk that these limitations pose to human subjects has precluded any large scale clinical trials to date.
