About this study

Official title: Application of 3-Dimensional Printing Guide Template and Pointed Lotus-style Regulator in Percutaneous Pedicle Screw Fixation for Thoracolumbar Fractures

This study aims to analysis the efficacy of the 3D printing percutaneous guide template in combination with the pointed lotus-style regulator in percutaneous pedicle screw fixation.

Read the detailed description

All thoracolumbar fractures patients receiving percutaneous pedicle screw fixation (PPSF) were enrolled and randomly divided into 3 groups. Patients in Group A received traditional PPSF, while patients in Group B received PPSF with flat end lotus-style regulator and patients in Group C received PPSF with pointed lotus-style regulator.

Being tested

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. First puncture success rate,number of insertions before reaching the desired position, number of fluoroscopy before reaching the desired position, radiation dosage before reaching the desired position, operation time before reaching the desired position

    All the operations were successfully completed. The number of pedicles successfully first pierced in group C was higher than that in group A and group B (P<0.05);The number of insertion, fluoroscopy and operation time before the insertion needle reached the ideal position, the total number and time of intraoperative fluoroscopy, and the intraoperative blood loss in group C were all significantly lower than those of group A and group B (P<0.05)

    Measured: twenty months

  2. VAS scores after surgery

    All patients were followed up 6 months after surgery. VAS scores at 1 day and 7 days after surgery were higher in Group A than those in other groups(P<0.05), but no differences were found VAS scores at 1 , 3 and 6 months after surgery in 3 groups.Specific methods: drawing a 10cm line on the paper, one end of the horizontal line is 0, that is painless; The other end is 10, which means severe pain; The intermediate part indicates different levels of pain. Asking the patient to mark the level of pain on a horizontal line according to how he or she feels. 0-2: meaning comfortable; 3-4: slight discomfort; 5-6: moderate discomfort; 7-8: Severe discomfort;9-10: Extreme discomfort.

    Measured: twenty-two months

Questions about this trial

What is this clinical trial studying?

A study testing Pointed lotus root regulator and guide template aided PPSF and Flat ended lotus root regulator and guide template aided PPSF in people with Vertebral Fracture, run by Ming Zhang 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 4 inclusion and 6 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 28 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?

First puncture success rate,number of insertions before reaching the desired position, number of fluoroscopy before reaching the desired position, radiation dosage before reaching the desired position, operation time before reaching the desired position (time frame: twenty months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04980131, which also lists 2 linked publications.

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 28 Jul 2021.
