About this study
Official title: The Impact of Topical Tranexamic Acid on Pre- and Post-operative Hemoglobin / Hematocrit in Isolated Operative Posterior Wall Acetabular Fractures: a Prospective, Randomized, Double-blinded, Multicenter Study
This multi-center, prospective study will evaluate the use of topical tranexamic acid (TXA - Cyklokapron; Pfizer, New York, NY) on pre-operative and post-operative hemoglobin (Hb)/hematocrit (Hct) in patients undergoing operative repair of isolated posterior wall (PW) acetabular fractures.
Read the detailed description
In this prospective, randomized, double-blinded, multi-center study comparing topical TXA with placebo, investigators will determine whether topical TXA utilization in isolated PW acetabular surgery has beneficial or detrimental effects.
In order to evaluate the delta between pre-operative and post-operative hemoglobin (blood loss parameters) in patients with isolated PW acetabular fractures that were treated with topical TXA or a placebo, investigators will prospectively enroll all eligible patients with the diagnosis of a closed, isolated, PW acetabular fracture that requires surgical fixation. Isolated PW fractures have been chosen to reduce confounding variables, particularly those associated with more complex fracture patterns including longer surgery duration and blood loss.
Each subject will have a pre-operative Hb and Hct drawn on the morning of surgery to establish a baseline level. Prior to surgery, subjects will be computer-randomized by pharmacy to one of two groups: a topical TXA group and a control group. The topical TXA group will be treated with 2 gm/100 ml of normal saline, while the control group will be treated with a placebo (normal saline) in a similar fashion to the TXA experimental group.
The surgeon and the operative team will be blinded as to whether the patient receives TXA or placebo.
Intraoperative transfusion requirements and estimated blood loss (EBL) will be recorded for every patient.
Hemoglobin and hematocrit values will be obtained on postoperative day one and two with routine morning blood draws (typically 5 am-9 am). Post-operative transfusion requirements prior to discharge will be recorded. All patients will have standard low molecular weight heparin DVT prophylaxis for four weeks post-operatively.
Prospectively demographic data will be collected. Injury and treatment data collected will include date of injury, mechanism of injury, laterality of injury, medical co-morbidities, associated injuries, date of surgery, operative time, estimated operative blood loss (EBL) from both anesthesia and operative surgeon, calculated operative blood loss, as well as hemoglobin/hematocrit as described, and blood transfusions.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This multi-center, prospective study will evaluate the use of topical tranexamic acid (TXA - Cyklokapron; Pfizer, New York, NY) on pre-operative and post-operative hemoglobin (Hb)/hematocrit (Hct) in patients undergoing operative repair of isolated posterior wall (PW) acetabular fractures.
Detailed description
In this prospective, randomized, double-blinded, multi-center study comparing topical TXA with placebo, investigators will determine whether topical TXA utilization in isolated PW acetabular surgery has beneficial or detrimental effects.

Isolated PW fractures have been chosen to reduce confounding variables, particularly those associated with more complex fracture patterns including longer surgery duration and blood loss.
Each subject will have a pre-operative Hb and Hct drawn on the morning of surgery to establish a baseline level.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Tranexamic Acid and Normal saline in people with Fracture of Posterior Wall of Acetabulum, run by University of Cincinnati 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 2 inclusion and 11 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 1 Apr 2025. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Hemoglobin (Hb) (time frame: Postoperative Day 2). 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 NCT05357079, which also lists 19 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 1 Apr 2025.
