A New Surgical Instrument in Treatment of Conlylar Fracture: Condylar Reductor
A study testing Condylar reductor in people with Mandibular Fracture, run by Junhui Cui.
Trial summary
In condylar fracture surgery, reduction is the most difficult step and the key factor which determined the postoperative outcome. Therefore, the aim of this study is to develop a new instrument, which the investigators call condylar redactor, to assist the surgeon to reduct the condylar segments effectively.

About this study

Read the detailed description
In this prospective cohort study, it involved condylar fractures patients who were received surgical treatment from January 2014 to June 2016. Patients in the experimental group were treated with the condylar reductor, and patients in the control group were treated with the traditional surgical instruments. The primary outcome variable was reduction time and reduction rate. The continuity correction X2 and test student t test were used.

Questions about this trial
What is this clinical trial studying?
A study testing Condylar reductor in people with Mandibular Fracture, run by Junhui Cui.
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 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 1 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.
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?
intraoperative reduction time (time frame: intraoperative). 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 1 Aug 2016; AzTrials last refreshed its copy on 8 Nov 2026.
