Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Following free-flap harvest (either anterolateral thigh flap or radial forearm flap), a biodegradable polyurethane dermal matrix sealed with a non-biodegradable polyurethane film will be implanted into the donor site. When integrated, the film is removed and a thin split skin graft applied to the integrated neo-dermis.
Intervention code [1] 266875 0
Treatment: Devices
Comparator / control treatment
Comparison will be made against data collected in 2010 and 2011 in porcine wounds of similar depth where a variety of treatments were employed. These included healing by secondary intention, implantation of unsealed polymer matrices, implantation of sealed polymer matrices, matrices with immediate split skin graft application, matrices with delayed split-skin graft application, matrices with sealing membranes of different thicknesses.
Control group
Historical

Outcomes
Primary outcome [1] 269096 0
Appearance of the donor site compared to historical data. Assessment will be by clinical appearance (incorporation of the foam is visible and progressive to day 7 then consolidates), ease of delamination of the sealing membrane in historical comparison to Integra dermal regeneration template, Visitrak wound measurement to assess degree of contraction.
Timepoint [1] 269096 0
Weekly to 6 weeks, then monthly to 12 months
Secondary outcome [1] 276922 0
Function of the donor site compared to historical data. This will be assessed by clinical means (pinching, shearing mobility, visibilty or otherwise of deeper structures (eg tendons in free radial forearm flap donor sites).
Timepoint [1] 276922 0
Weekly to 6 weeks, then monthly to 12 months
