Urinary bladder matrix devices support closure in complex sacral wounds

The management of sacral wounds is often complicated by patient comorbidities and anatomical factors. This retrospective case series describes the management of 5 complex sacral wounds in which UBM devices were applied to facilitate wound closure. The wounds in this series were exacerbated by comorbidities and challenging wound presentations including tunneling and exposed bone. In this series, application of UBM particulate and sheets supported progressive wound closure, marked by neo-tissue formation and depth reduction with closure of tunneling in all cases. Results from this series underscore the utility of UBM devices in the management of sacral wounds and especially those further hindered by extensive tunneling.
