Surgical site infections following lower extremity amputations have been reported in up to 40% of patients. Surgical site infections have significant morbidity and even mortality in terms of emergency room visits, length of hospital stay, reamputation rates and death. Since its introduction, negative pressure wound therapy has been demonstrated to promote wound healing and possibly decreasing the need for future amputations. The aim of the study is to provide level I evidence for the use of negative pressure wound therapy devices in patients undergoing lower extremity amputation.
