About this study
The study is aimed at patients with low back and leg pain. The experimental group of patients underwent selective lumbar nerve root block puncture under real-time ultrasound-CT fusion imaging by sonographers, and the control group underwent puncture under the guidance of ultrasound alone by sonographers.
Read the detailed description
A total of 60 patients with low back and leg pain were randomly divided into two groups, 30 people in each group. Patients in the experimental group underwent selective lumbar nerve root block puncture under the real-time ultrasound-CT fusion imaging of the sonographer, and the control group underwent puncture under the sole ultrasound guidance of the sonographer. This study was used to compare the difference between the effects of pure ultrasound guidance and ultrasound-CT fusion imaging guidance on selective lumbar nerve root block.

Questions about this trial
What is this clinical trial studying?
A study testing real-time ultrasound-CT fusion imaging and ultrasound alone in people with Low Back Pain, run by Peking University Third Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
1 month VAS pain score (time frame: VAS pain scores were performed 1 month after surgery). The study lists 4 primary outcomes in all. 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 16 Jul 2021.
