About this study
Official title: Comparison of Low Dose Computed Tomography to Conventional Dose Computed Tomography in the Evaluation of Distal Radius Fractures
This study is a prospective, departmental funded study examining the outcomes of Low Dose CT scans compared to Conventional Dose CT scans in patients who present to Duke University with a Distal Radius Fracture.
Read the detailed description
The purpose of this study is to compare the use of a conventional dose computed tomography scan (C-CT) to a low dose computed tomography scan (L-CT) in the assessment of articular displacement, and development of a treatment plan for intraarticular distal radius fractures in an effort to reduce the radiation exposure to future patients with this injury pattern. Reviewers will be tasked with reporting data aimed at investigating 3 primary outcome measures: 1) Are L-CT images of sufficient quality to be used for diagnostic purposes, 2) Can accurate measurements of step and gap displacement be made on L-CT images, 3) Do proposed treatment plans change with the use of L-CT relative to those chosen based on C-CT images We hypothesize that reviewers will find L-CT images of sufficient image quality for diagnostic purposes, measurements of step and gap displacement will not be significantly different between L-CT and C-CT, and no significant differences in treatment options will be chosen based on the use of L-CT rather than C-CT for the same fracture. The secondary aim will be to evaluate the interobserver and intraobserver reliability of L-CT in evaluating intraarticular fractures of the distal radius.

Questions about this trial
What is this clinical trial studying?
An observational study of Radius Fractures, run by Duke University at 1 site in United States.
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 3 inclusion and 5 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 10 Sep 2020. 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 United States. 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?
Low Dose CT Images of Sufficient Diagnostic Quality (time frame: 12 months.). 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 NCT03423043, which also lists 12 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 10 Sep 2020.
