About this study

Official title: The Difference of Two and Three Fluoroscopic Views of Sacrum for Percutaneous Sacroiliac Screw Insertion in High Energy Posterior Pelvic Ring Injured Patients, a Double-blinded Randomized Controlled Trial

The goal of this clinical trial is to learn about the surgical techniques of percutaneous sacroiliac screw fixation both the two-view fluoroscopic technique (sacral inlet and outlet views) and the standard three-view fluoroscopic technique (lateral, sacral inlet, and sacral outlet views).

The main questions it aims to answer is:

Read more
  • Is there any difference of the operative time, intraoperative radiation exposure time, screw malposition rate, and postoperative neurological complication rate for percutaneous pelvic screw fixation between two techniques?

Researchers will compare two surgical techniques of percutaneous sacroiliac screw fixation in high energy posterior pelvic ring injured patients.

Participants will:

  • Be examined neurological status carefully before and after the operation
  • Get both preoperative and postoperative CT scan
  • Undergo the percutaneous sacroiliac screw(s) fixation with or without anterior plating fixation
Being tested
Percutaneous sacroiliac screw fixation using two or three fluoroscopic views

What is being measured

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

  1. Operative time

    Operative time in minutes that takes for insertion of guide pin of cannulated SI screw; From the time of skin incision to the final acceptable positioning of the guide pin (prior to screw insertion)

    Measured: perioperative record

Secondary outcomes (3)
  1. Radiation Exposure Time

    Cumulative fluoroscopy time in seconds; From the first fluoroscopic image to the final image confirming guide pin placement

    Measured: Perioperative record

  2. Neurological complications by physical examinations and symptoms

    Neurological examinations will be assessed and recorded by an independent orthopedic resident blinded to the allocation. The evaluations include radiation pain by visual analog score, L5 and S1 motor power by physical examination motor grading scale, L5 and S1 sensation deficit (yes or no), perianal sensation deficit (yes or no), bowel bladder symptoms (yes or no), sphincter tone deficit (yes or no)

    Measured: Immediate postoperative to two months after operation

  3. Screw malposition

    Screw malpositions of S1 screw (yes or no) include cortical breakage (sacral ala, endplate, anterior cortex, ilium), foraminal penetration and canal penetration

    Measured: Two months after operation, Postoperative CT scan will be evaluated for screw position.

Questions about this trial

What is this clinical trial studying?

A study testing Percutaneous sacroiliac screw fixation using two or three fluoroscopic views in people with High-energy Trauma and Sacral Fractures, run by Chonburi hospital at 1 site in Thailand.

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 2 inclusion and 10 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: under way, not looking for participants, as of the sponsor's last update on 6 May 2026. 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 Thailand. 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?

This study is still under way. Results are not available in the source record yet.

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?

Operative time (time frame: perioperative record). 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 NCT07571798, which also lists 15 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 6 May 2026.
