Overview
The goal of this study is to explore if an adipose-based therapeutic strategy can treat contracted scars secondary to soft-tissue burn wounds in injured individuals, especially those with severe burns or soft-tissue loss. The main question it aims to answer are:
\- Can autologous layered composite grafting demonstrate non-inferiority compared to full-thickness skin grafting for delayed reconstruction of post-burn or trauma scar contracture?
Researchers will compare the single-stage autologous layered composite grafting method to traditional methods to see if it improves healing outcomes, minimizes scarring, and reduces infection risk.
Participants will:
- Receive fat grafting at time of scar revision.
- Undergo simultaneous split-thickness skin grafting for full soft-tissue reconstruction.
Description
Soft-tissue injuries from blasts, burns, or multiple traumas can cause severe damage, leading to loss of function, lower quality of life, long recovery times, and inability to work. When these injuries involve deep burns or full-thickness tissue loss in areas that move a lot, they are especially difficult to treat due to the risk of scarring, stiffness, and tissue sticking together. There is a need for a reliable, single-stage treatment that can provide soft, flexible tissue reconstruction with minimal risk, cost, and, complexity. To address this issue, the investigators propose a fat-based approach to reconstruction. Fat tissue is easily available from the patient's own body and carries many benefits in reconstructive surgery. Our team has shown that using a layer of fat immediately in treatment creates a soft, vascular layer that reduces scarring, improves tissue volume, and supports a one-stage, multi-layer reconstruction without the need for complex surgery or causing harm to the donor area. The purpose of this study is to compare this reconstructive approach under the following conditions:
• Demonstrate non-inferiority of autologous layered composite grafting to full-thickness skin grafting for delayed reconstruction of post-burn/trauma scar contracture.
Evaluators including dedicated observers will be blinded to treatment group/strategy.
