About this study
Lumbar Transforaminal Epidural Injection is helpful for the treatment of lumbosacral radicular pain.
Tunnel view technique is the basis of X-ray assisted intervention. In this technique, it is necessary to handle the block needle in order to adjust the direction of needle to the tunnel view toward target. If a mirror is used during needle handling, overall procedure time and radiation exposure can be reduced.
Read the detailed description
- A planned Fluoroscopically Guided Lumbar Transforaminal Epidural Injection should be performed after receiving the informed consent of the patient.
- This study is single-blind because it is not possible to blind the practitioner performing the injection.
- Subjects were randomly assigned to the normal method group (group A) and the mirror use group (group B) by a random random number table, and the possibilities for belonging to any group were all the same and can not be artificially controlled by researchers.
- After the procedure, a resident who does not know of this study records the radiation exposure time displayed on the monitor and the overall procedure time
- Being tested
- Fluoroscopically Guided Lumbar Transforaminal Epidural Injections, conventional manner
- Keywords
- epidural steroid injection, radiation exposure, mirror
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Fluoroscopically Guided Lumbar Transforaminal Epidural InjectionsProcedure or surgery
Lay the subject down on the stomach and hold the pillow on the stomach. The skin of the injection area is sterilized by aseptic method and covered with aseptic pouch. After confirming the level of he vertebrae around the C-arm and aligning the anteroposterior view of the endplate of the vertebral body, rotate the C-arm 20~30 degrees diagonally in the direction to be performed. After confirming the best Scotty dog view, confirm the final target point at 6 o'clock directly below the pedicle. At this position, the skin point is marked on the skin. And then both groups proceed in parallel with the beam direction of the transducer with the tunnel view technique until the needle reaches the back of the vertebral body at the level of the spinal nerve roots. At this time group A uses a mirror and group B dose not. The final reach of the target point (ideal depth) is confirmed through the anterior and posterior views and lateral views.
conventional mannerProcedure or surgery
A portable mirror is located at the side of surgical table and used in this procedure.
| Study group | Role | What they receive |
|---|---|---|
| normal method group (group A) | Active comparator | A mirror is not used in tunnel view technique (conventional manner) Receives: Procedure: conventional manner |
| mirror use group (group B) | Experimental | A mirror is used in tunnel view technique Receives: Procedure: Fluoroscopically Guided Lumbar Transforaminal Epidural Injections |
What is being measured
The primary outcome is the main question the study is designed to answer.
radiation exposure time(second)
In both groups, overall procedure time recorded on the monitor is recorded after the procedure is over.
Measured: Immediately after the procedure

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jan 2019; AzTrials last refreshed its copy on 7 Nov 2026.
