About this study
This study is a clinical, multicentric, randomised open trial. The objective is to evaluate the efficiency, in terms of wound healing speed, of peroperative application of autologous platelets gel versus standardized wound dressing. The wound Healing model used in this study is the " open palm " surgical treatment of Dupuytren's disease.
Dupuytren's disease is a fibroproliferative disease of the palmar and digital fascia of the hand that may lead to a fixed flexion contracture of the fingers.

The main indication for surgery is the loss of finger extension. In some cases of palmar Dupuytren's disease the surgical removal of diseased tissues may lead to a cutaneous loss of substance (" open palm technique "). This loss of substance is treated using vaseline dressing and the wound healing is obtained in 4 weeks.
Autologous platelets gel (Platelet Rich Fibrin) is obtained from the patient's own blood. Some recent studies have shown that it speeds up the wound healing and enhances the quality of the scar.
PRF belongs to a new generation of autologous platelet gel that are easily obtained after centrifugation of patient's own blood.
The Platelet Rich Fibrin (PRF) contains many wound healing factors : Three pro inflammatory cytokines ( IL1,IL6, TNF-alpha) , one anti-inflammatory cytokine (IL4) and a growth factor (VEGF).
The study will be running on 60 days, starting from the operation day. The wound healing evaluation will be achieved at day1, day2, day7, day14, day 21 day 28 and day 60.
The inclusion criteria are : age over 18, Dupuytren's disease with an indication of surgical treatment using the open palm technique, patients having signed the agreement form.
80 patients will be included in the study and divided into 2 groups . The first group of patients will receive PRF and the other group will receive vaseline dressings.
The speed and the quality of wound healing will be compared.We will also compare the number of patients with a complete wound healing at day 21 . Moreover,we will evaluate the pain during the dressings' change and the bleeding of the palmar wound.
For the wound healing speed , a difference of 7 days between the two groups will be considered as statistically significant.
Statistical analysis will be achieved using Chi2 test and Logrank test.
Read the detailed description
Main evaluation criteria :
Time duration between the operation and the complete wound healing. The wound healing is considered complete when the skin is closed and when the patient do not need to have dressings. A picture of the wound at the end of the wound healing process is taken for each patient.
Secondary criteria of evaluation :
At day 1, day7, day 14, day 21 and day 28 two data will be collected :
- The pain during the dressings' change using a visual scale going from 0 (no pain) to 10 (very painful).
- The bleeding (and "exudate") of the wound which can be absent, low, moderate or abundant.
The investigators will collect all the side effects described by the patients for each wound healing technique.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Autologous platelets gel and Vaselitulle in people with Dupuytren's Contracture, run by Centre Hospitalier Universitaire de Nice at 2 sites 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 4 inclusion and 6 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 20 Mar 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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?
Time duration between the operation and the complete wound healing. (time frame: 18 months). 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 NCT00931567, 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.
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 20 Mar 2012; AzTrials last refreshed its copy on 8 Nov 2026.
