Lumbosacral RadiculopathyNCT01836770
Epidural Contrast Flow Patterns of TESI Using the Inferior-Anterior Position as the Final Needle Tip Position.
An observational study of Lumbosacral Radiculopathy and Lumbar Herniated Nucleus Pulposus, run by George Washington University at 1 site in United States.
Trial summary
The purpose of this study is to describe the contrast flow patterns in the epidural space using the inferior-anterior approach with continuous fluoroscopic guidance, and determine how well this approach correlates with appropriate contrast flow patterns and with analgesia at follow up.

About this study
Official title: Epidural Contrast Flow Patterns of Transforaminal Epidural Steroid Injections Using the Inferior-Anterior Position as the Final Needle Tip Position.
The purpose of this study is to describe the contrast flow patterns in the epidural space using the inferior-anterior approach with continuous fluoroscopic guidance, and determine how well this approach correlates with appropriate contrast flow patterns and with analgesia at follow up. This knowledge may prove useful in guiding physician practice patterns in the non-surgical management of low back pain.
Hypothesis: The investigators hypothesize that there will be suitable (ventral/anterior) epidural contrast spread based on inferior-anterior needle-tip position, particularly with appropriate needle tip position.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Transforaminal Epidural Steroid Injection | Patients with a history of lumbosacral radiculopathy or lumbar herniated nucleus pulposus, scheduled for Transforaminal Epidural Steroid Injection. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Contrast flow patterns
Contrast flow patterns will be used as the primary outcome measure. The statistical test to be employed is to compare the proportions of patients in the study who experienced posterior flow, anterior flow and if that anterior flow had spread to more than 1 vertebral level in either direction, what that direction was, and the presence or absence of vascular flow.
Measured: 3 Months
Secondary outcomes (1)
VAS pain score
VAS Pain Score - The statistical test to be employed is Wilcoxon Signed Rank Test to compare if there is a difference in pain score at appointments 1 months and 3 months post-injection relative to pre-injection.
Measured: 3 months

Are results available for this study?
The study was stopped early (reason given: lack of enrollment; terminated by the Principal Investigator). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Contrast flow patterns (time frame: 3 Months). It is what the study was designed to measure, not a finding.
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 5 Mar 2018; AzTrials last refreshed its copy on 6 Nov 2026.
