Negative Pressure Wound Therapy for Open Fractures

To the Editor Dr Costa and colleagues for the UK WOLLF Collaborators found no improvement in disability at 12 months in patients with severe open fractures of the lower limb who received negative pressure wound therapy (NPWT) vs standard wound management.1 I would like to address some issues in the study.

First, differences between NPWT and standard wound dressing include frequency of dressing changes (which can influence patient pain and discomfort level) and cost. These factors were not analyzed but should be taken into account when reaching conclusions on the overall benefit of NPWT.
