Study summary

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

Read the 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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Low extremity fracture requiring surgical treatment
  • Uncontrolled diabetes ( > 7.0 or random glucose > 200 mg/dL)
  • Age 18 years or older
  • Able to provide
  • English or Spanish speaker

Exclusion criteria

Exclusion Criteria:

  • Known allergy to prescribed antibiotic and pre-determined alternatives
  • Open fractures
  • Current infection requiring antibiotic treatment
  • status (chemotherapy, immunosuppressant medications)
  • End-stage renal disease that medication dosing cannot be adjusted for
  • Pregnant or breast-feeding
  • Unable to comply with follow-up
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2026 (actual). Primary completion is estimated for Dec 2027, 20 months after the start.

Of 149 non-industry phase 4 interventional studies under Diabetes Mellitus, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 53. This study's planned 20 months is below that.

Counting every sponsor, half of 197 studies reached it within 24 months; a quarter within 13 and three quarters within 40.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 8, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
