Comparison of the Effectiveness of Two Medical Compression Bandage Application Techniques by Measuring Interface Pressures Depending on Whether or Not the Heel is Included in Patients With Open Venous Ulcers
A study testing Heel-free bandage in people with Venous Ulcer, run by Nantes University Hospital at 1 site in France.
Trial summary
The importance of wearing medical compression to heal the venous ulcer has already been shown. However, no studies have been carried out on variations in medical compression tape and their impact on interface pressures which explains the lack of consensus on how to lay, including or not to include the heel.

About this study
Official title: Comparison of the Effectiveness of Two Medical Compression Bandage Application Techniques by Measuring Interface Pressures Depending on Whether or Not the Heel is Included in Patients With Open Venous Ulcers: Non-inferiority, Controlled, Randomized Trial
The importance of wearing medical compression to heal the venous ulcer has already been shown. However, no studies have been carried out on variations in medical compression tape and their impact on interface pressures which explains the lack of consensus on how to lay, including or not to include the heel. Studies on adherence to patients with medical compression have been carried out showing that one of the determining factors is comfort. The investigators therefore wish to conduct a randomized open prospective quantitative study comparing these two modes: including or not the heel .

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Heel-free bandageOther
The bandage is made by leaving the heel uncovered.
| Study group | Role | What they receive |
|---|---|---|
| Heel included | No intervention | The bandage is made by including the heel as recommended in routine. |
| Heel not included | Experimental | he bandage is made by leaving the heel uncovered. Receives: Other: Heel-free bandage |
What is being measured
The primary outcome is the main question the study is designed to answer.
Interface Pressure at V3
Compare the interface pressure measurements generated by a medical compression bandage between two groups of patients with open venous ulcer(s) :
- experimental group: uncovered heel
- control group: heel covered by the bandage.
Measured: At V3 (i.e. between 4 to 8 weeks): 48h after the final bandagin (which occurs at V2)
Secondary outcomes (5)
Ankle Circumference
Compare the evolution or appearance of an edema in the ankle. The circumference of the ankle is measured with a tape measure using a technique called the figure of 8.
Measured: Day 0 and the last day at V3 (between week 4 and week 8)
Interface Pressure at V2
Compare, between the two groups, the interface pressures measured during the installation of bandage at home by the home nurse (V2 follow-up visit), compared to the recommended pressures (30-40 mmHg)
Measured: 48 hours before the last visit of the protocol V3 (V3 which occurs between 4 to 8 weeks)
Interface Pressure Between V2 and V3
Compare, between the two groups, the evolution of interface pressures after 48 hours of bandage wear.
Measured: At V2 and at V3, 48 hours apart (V3 which occurs between 4 to 8 weeks)
Patient Satisfaction: Questionnaire
Between the two groups, compare patient satisfaction with a heterogeneous questionnaire.
There is no scale or score. It is asked which type of bandage the patient prefers: with or without heel included?
Measured: At the last visit of the protocol (Between 4 and 8 weeks)
Number of Bandage Repairs
Evaluate the number of bandage repairs required to reach the recommended therapeutic pressure
Measured: Day 0

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The importance of wearing medical compression to heal the venous ulcer has already been shown. However, no studies have been carried out on variations in medical compression tape and their impact on interface pressures which explains the lack of consensus on how to lay, including or not to include the heel. Studies on adherence to patients with medical compression have been carried out showing that one of the determining factors is comfort. The investigators therefore wish to conduct a randomized open prospective quantitative study comparing these two modes: including or not the heel .

Questions about this trial
What is this clinical trial studying?
A study testing Heel-free bandage in people with Venous Ulcer, run by Nantes University Hospital at 1 site in France.
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 5 inclusion and 4 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 19 Mar 2026. 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 France. 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?
Yes. Results are posted in the registry (first posted 19 Mar 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?
Interface Pressure at V3 (time frame: At V3 (i.e. between 4 to 8 weeks): 48h after the final bandagin (which occurs at V2)). 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 NCT04046120, which also lists 1 linked publication.
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.
