Introduction:A polyurethane material (NovoSorbTM Biodegradable Temporising Matrix or “BTM”; PolyNovo Biomaterials Pty Ltd, Port Melbourne, Victoria, Australia) has been derived and evaluated over the last decade, with various publications documenting its use in reconstruction. There is no local experience published, with the use of this novel product within New Zealand, to date. We hereby present our first-hand experience with the use of this material on the patients within our region.

Method:The BTM was employed in a series of complex wound scenarios in our unit, including large hand and foot defects following debridement for necrotising infection with exposed bone/tendons and/or underlying osteomyelitis. We followed the published protocols for BTM application and dressing changes. A total of 8 cases had been performed to date.

Results:Application, integration, delamination, and secondary coverage with split-skin grafting proceeded without complication. Photographic records were taken at every intervention. The average time frame between application and skin grafting is 40 days. The results to date demonstrated robust reconstruction of defects that otherwise would require more complex surgeries.

Conclusion:Our local experience enabled us to incorporate this novel product into our clinical practice on various complex wounds that previously would not be considered suitable to use synthetic dermal substitute. Longer-term follow-up is required and would be the basis of future studies.
