Accelerated flap coverage for severe lower leg injuries

Official title: Accelerated Flap Coverage Versus Standard Timing in the Treatment of Severe Lower Extremity Musculoskeletal Injuries

Run by Johns Hopkins University · NCT06293469 · Data updated 2026-11-12

This study is testing if getting surgery to cover severe leg injuries within 72 hours helps reduce infections better than the usual timing for treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with acute open fractures or dislocations below the knee requiring flap coverage.

Probably not a fit

Patients who are expected to undergo primary amputation or have critical limb ischemia will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to compare the effectiveness of accelerated flap coverage within 72 hours of injury to standard flap coverage timing in patients with severe lower extremity open fractures and dislocations. Participants will be randomly assigned to one of the two treatment groups, and the primary outcome will assess infection-related complications and overall clinical status six months post-randomization. The study seeks to address the critical knowledge gap regarding optimal timing for soft tissue coverage to reduce infection rates, which are currently high in the U.S. compared to the U.K. guidelines. A total of 356 participants will be enrolled in this trial.

Why it matters

Potential benefit: If successful, this approach could significantly reduce infection rates and improve recovery outcomes for patients with severe lower extremity injuries.

How similar studies have gone: While there is promising data supporting early flap coverage, this trial is necessary to provide definitive evidence, as similar studies have not yet established a consensus.

Who can join: the full rules

Show full inclusion / exclusion criteria
The inclusion criteria are:

1. Patients 18 years of age or older.
2. Severe lower extremity open fracture and/or dislocation below the knee requiring an acute flap for management of the musculoskeletal injury.
3. Will have all planned flap surgeries performed by a participating surgeon or delegate.
4. Able to be randomized within 48 hours of injury.

The exclusion criteria are:

1. Site is unable to implement the accelerated flap protocol due to local logistics.
2. Primary amputation anticipated prior to attempted flap for management of the injury.
3. Critical limb ischemia that requires re-vascularization for limb perfusion.
4. Chronic or acute infection at or near the musculoskeletal injury site at the time of initial injury surgery.
5. Burns at the musculoskeletal injury site.
6. Incarceration.
7. Expected injury survival of less than 12 months.
8. Terminal illness with expected survival of less than 12 months.
9. Currently enrolled in a trial that does not permit co-enrollment.
10. Declined to provide informed consent.
11. Unable to obtain informed consent due to language barriers.
12. Unable to obtain informed consent because a legally authorized representative was unavailable.
13. Anticipated problems, in the judgment of research personnel, with maintaining follow-up with the patient.
14. Prior enrollment in the trial.
15. Eligible patient or LAR was not approached within screening window (missed participant).
16. Other reason to exclude the patient, as approved by the Principal Investigators.
