About this study

Official title: Periosteal Distraction Combined With Skin Grafting for the Treatment of Diabetic Foot Ulcers: A Prospective, Randomized, Controlled Study

This study is a single-center, prospective, randomized controlled trial aimed at evaluating whether periosteal distraction combined with autologous split-thickness skin grafting can significantly improve graft survival rate at postoperative day 14 compared with skin grafting alone in patients with diabetic foot ulcers (Wagner grade 2-3 or post-amputation). A total of 104 eligible patients will be randomly assigned to either the experimental group (periosteal distraction + skin grafting, n=52) or the control group (skin grafting alone, n=52). Secondary outcomes include time to complete epithelialization, wound healing quality (BWAT score at 3 months), ulcer recurrence rate (at 6 months), foot function (AOFAS score), quality of life (DFS-SF score), and safety profile. This study aims to address the critical clinical bottleneck of poor graft survival in ischemic wound environments, providing a novel, minimally invasive, and synergistic treatment paradigm for diabetic foot ulcers.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Periosteal DistractionProcedure or surgery

    A minimally invasive surgical technique based on the Ilizarov tension-stress principle. The periosteum is circumferentially stripped 1-1.5 cm from the wound edge, elevated 0.5-1.0 cm using K-wire drilling and suspension, followed by biological material coverage to promote vascularization. The distraction is applied at a rate of 1 mm per day to activate cell proliferation and angiogenesis.

  • Skin GraftingProcedure or surgery

    Autologous split-thickness skin harvested using a dermatome, trimmed to match the wound size, and transplanted onto the wound bed after debridement. The graft is secured with vaseline gauze and antibiotic dressing, followed by pressure bandaging and splint immobilization.

Study groupRoleWhat they receive
Periosteal Distraction + Skin GraftingExperimentalPatients receive periosteal distraction combined with autologous split-thickness skin grafting. Surgical procedure includes debridement, periosteal stripping and elevation (0.5-1.0 cm) using K-wire drilling, biological material coverage for vascularization, skin graft fixation, and postoperative management with delayed dressing change at day 5-7 and suture removal at day 14.
Receives: Procedure: Periosteal Distraction; Procedure: Skin Grafting
Skin Grafting AloneActive comparatorPatients receive autologous split-thickness skin grafting alone. Surgical procedure includes debridement, skin graft harvesting and transplantation, followed by postoperative management with first dressing change at day 3, suture removal at day 10-14, and gradual weight-bearing after ≥4 weeks.
Receives: Procedure: Skin Grafting

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Graft Survival Rate

    Survival area of skin graft as a percentage of the original graft area at postoperative day 14. Measured using a transparent grid film (1 cm² grid) combined with digital photography. Two blinded assessors independently measure the area; a third assessor arbitrates if the difference exceeds 10%. Formula: (surviving graft area / initial graft area) × 100%.

    Measured: Day 14 post-surgery

Secondary outcomes (5)
  1. Time to Complete Epithelialization

    Number of days from surgery to complete wound closure, defined as 100% epithelial coverage without drainage or scab. Assessed daily by clinical examination combined with digital photography.

    Measured: Assessed daily from surgery until closure, up to 3 months

  2. Wound Healing Quality Assessed by BWAT Score

    Bates-Jensen Wound Assessment Tool (BWAT) score at 3 months post-surgery. The scale ranges from 13 to 65 points, with higher scores indicating poorer wound healing quality. Assessed by blinded independent outcome assessors.

    Measured: Month 3 post-surgery

  3. Ulcer Recurrence Rate

    Proportion of participants developing a new ulcer ≥1 cm² at the original graft site within 6 months post-surgery. Confirmed by clinical examination and photographic documentation.

    Measured: Month 6 post-surgery

  4. Foot and Ankle Function Assessed by AOFAS Score

    American Orthopaedic Foot and Ankle Society (AOFAS) score at 6 months post-surgery. The scale ranges from 0 to 100 points, with higher scores indicating better functional recovery. Assessed by blinded independent outcome assessors.

    Measured: Month 6 post-surgery

  5. Quality of Life Assessed by DFS-SF Score

    Diabetic Foot Ulcer Scale Short Form (DFS-SF) score at 6 months post-surgery. The scale ranges from 0 to 100 points, with higher scores indicating better quality of life. Assessed by blinded independent outcome assessors.

    Measured: Month 6 post-surgery

Questions about this trial

What is this clinical trial studying?

A study testing Periosteal Distraction and Skin Grafting in people with Diabetic Foot Disease and Wound Healing, run by Hu Zhicheng.

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 9 inclusion and 11 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: opening soon, as of the sponsor's last update on 22 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Hu Zhicheng (020-87755766-8235, huzhch5@mail.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Graft Survival Rate (time frame: Day 14 post-surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 22 Apr 2026.
