Ultrasound-guided vs fluoroscopy-guided lumbar nerve injections for leg/back pain

Official title: Ultrasound-Guided Versus Fluoroscopy-Guided Selective Lumbar Nerve Root Injections for Lumbosacral Radiculopathy: A Randomized Clinical Trial

Run by Tanta University · NCT07627308 · Data updated 2026-11-12

In adults with leg and lower back nerve pain, this study tests whether ultrasound guidance works as well as traditional X-ray guidance for lumbar nerve root injections.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–75 with MRI-confirmed lumbar radiculopathy due to disc herniation or foraminal stenosis who have not improved after at least 3 months of conservative care.

Probably not a fit

Patients with isolated S1 radiculopathy, significant spinal deformities, prior lumbar surgery, or contraindications to injections may not benefit.

What this trial studies

This randomized clinical trial compares ultrasound-guided selective lumbar nerve root injections to fluoroscopy-guided injections in adults with lumbosacral radiculopathy. Participants are assigned 1:1 to receive a targeted nerve injection of a steroid and numbing medicine using either ultrasound or fluoroscopy. The study aims to see if ultrasound provides similar pain relief at 3 months, supports better recovery in daily activities, and offers comparable speed and safety to fluoroscopy while eliminating radiation exposure. It is conducted at Tanta University Hospitals and uses MRI-confirmed nerve compression with prior conservative treatment failure. Primary outcomes focus on pain relief, functional improvement, and safety profiles of the two guidance methods.

Why it matters

Potential benefit: If ultrasound guidance is as effective as fluoroscopy, patients could receive comparable pain relief without radiation exposure.

How similar studies have gone: This study builds on growing evidence that ultrasound guidance can visualize soft tissues and nerves, with prior work suggesting comparable effectiveness to fluoroscopy in spinal injections.
