Comparison of Gait in Syndesmosis Injuries Treated With Screw Fixation vs Suture Button
A study testing Suture Button vs Screw Fixation in people with Acute Disruption of Ankle Syndesmosis, run by University of Nebraska at 3 sites in United States.
Trial summary
Injuries to the distal tibiofibular syndesmosis are common and occur in an estimated 25% of all rotational ankle fractures. Anatomic reduction of the syndesmosis has been associated with improved functional outcome as well as decreased rates of posttraumatic arthritis. Read more about this study

About this study
Injuries to the distal tibiofibular syndesmosis are common and occur in an estimated 25% of all rotational ankle fractures. Anatomic reduction of the syndesmosis has been associated with improved functional outcome as well as decreased rates of posttraumatic arthritis. Both screw fixation and suture fixation have become accepted standards of care for treatment of syndesmotic injuries. Recent literature would suggest trends favoring suture fixation over screw fixation with improved quality of syndesmotic reduction, postoperative range of motion, and improved maintenance of syndesmotic reduction. However, the evidence remains heterogeneous, and patient reported outcomes have failed to show a superiority of one method over the other. Additionally, there have been no studies that demonstrate objective gait outcomes comparing screw versus suture fixation for syndesmotic injuries.
Read the detailed description
This will be a prospective randomized study. Patients with isolated rotational ankle injuries with syndesmotic instability will be randomized to either screw fixation or suture fixation for treatment of their syndesmotic injury. Patients will be followed postoperatively for one year following surgery with documentation of both clinical outcomes and subjective patient reported outcomes. Additionally, postoperative gait patterns will be measured and compared between patients who had syndesmotic injuries treated with screw fixation versus suture fixation

Patient reported outcomes - PROMIS LE (Patient-Reported Outcomes Information System Lower Extremity)
The PROMIS LE is a computer-adaptive test that reports a score of patient-perceived physical functioning (walking and mobility) specific to the lower extremity. Scores are reported as T scores, with a score of 50 equal to the mean of the general population. Higher scores indicate more favorable physical function. Theoretical maximum and minimum scores are 100 and 0, respectively.
Measured: 3 months, 6 months, and 1 year
Patient reported outcomes - Olerud-Molander Score
The Olerud-Molander Score was designed to score patient-reported outcomes regarding symptoms after ankle fracture. Scale minimum and maximum are 0 and 100, respectively, with a higher score indicative of improved outcome.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Injuries to the distal tibiofibular syndesmosis are common and occur in an estimated 25% of all rotational ankle fractures. Anatomic reduction of the syndesmosis has been associated with improved functional outcome as well as decreased rates of posttraumatic arthritis. Both screw fixation and suture fixation have become accepted standards of care for treatment of syndesmotic injuries. Recent literature would suggest trends favoring suture fixation over screw fixation with improved quality of syndesmotic reduction, postoperative range of motion, and improved maintenance of syndesmotic reduction. However, the evidence remains heterogeneous, and patient reported outcomes have failed to show a superiority of one method over the other. Additionally, there have been no studies that demonstrate objective gait outcomes comparing screw versus suture fixation for syndesmotic injuries.
Detailed description
This will be a prospective randomized study. Patients with isolated rotational ankle injuries with syndesmotic instability will be randomized to either screw fixation or suture fixation for treatment of their syndesmotic injury. Patients will be followed postoperatively for one year following surgery with documentation of both clinical outcomes and subjective patient reported outcomes. Additionally, postoperative gait patterns will be measured and compared between patients who had syndesmotic injuries treated with screw fixation versus suture fixation

Questions about this trial
What is this clinical trial studying?
A study testing Suture Button vs Screw Fixation in people with Acute Disruption of Ankle Syndesmosis, run by University of Nebraska at 3 sites 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 4 inclusion and 7 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: stopped early, as of the sponsor's last update on 13 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites 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 was stopped early (reason given: Follow-up and consent was difficult and accrual was not being met.). Results are not available in the source record.
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?
Gait parameter - Step length (time frame: 3 months). The study lists 21 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 13 Jan 2026.
