Extended Oral Antibiotic Prophylaxis in Diabetic Fracture Patients

May 6, 2026 updated by: Taylor M. Yong, Texas Tech University Health Sciences Center, El Paso

Extended Oral Antibiotic Prophylaxis in Diabetic Patients With Lower Extremity Fracture: A Multicenter Pilot Randomized Controlled Trial

The goal of this clinical trial is to learn if taking an antibiotic pill for 7 days after surgery reduces the risk of wound infection in adults with poorly controlled diabetes who have surgery to fix a broken bone in the leg, ankle, or foot. It will also learn about the safety of the extended antibiotic course. The main questions it aims to answer are:

Does a 7-day antibiotic course after surgery lower the rate of wound infection within 90 days? What medical problems do participants have when taking the extended antibiotic course?

Researchers will compare a 7-day course of an oral antibiotic (cefadroxil) to standard care (no additional antibiotics after surgery) to see if the extended course reduces infections.

Participants will:

Take an antibiotic pill or receive standard care for 7 days after surgery Receive a phone call from the study team about 1 week after surgery Visit the clinic at 3 weeks, 6 weeks, and 3 months after surgery for checkups

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this research study is to investigate whether a 7-day course of an oral, prophylactic antibiotic following surgical fixation of a lower extremity fracture effectively decreases the risk of surgical site infection in patients with poorly controlled diabetes. Patients with an uncontrolled hemoglobin A1c greater than 7.0 or a random blood glucose greater than 200 mg/dL undergoing operative fixation of a closed fracture of the distal femur, patella, tibial plateau, tibial shaft, pilon, ankle, talus, calcaneus, or other operative foot fracture are considered high-risk for surgical site infection and are the target population for this study.

Study participants will be randomized to either a 7-day course of an oral prophylactic antibiotic following surgery (cefadroxil 500 mg twice daily, or an alternative regimen based on allergy status or methicillin-resistant Staphylococcus aureus colonization) or standard care with no additional antibiotics beyond the standard perioperative intravenous antibiotic dosing. All other standard perioperative fracture care will remain the same for both groups. Outcomes assessed will include superficial and deep surgical site infection occurring within 90 days of surgery, antibiotic-related adverse effects, and patient compliance with the extended antibiotic regimen.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
