title: Negative pressure wound therapy reduces deep infection rate in open tibial fractures.
abstract: OBJECTIVE
  To evaluate the effect of negative pressure wound therapy (NPWT) on deep infection rate in open tibial fractures.
  
  
  METHODS
  Retrospective cohort study. Data was collected from medical records and radiographs.
  
  
  METHODS
  Two level-1 trauma centers.
  
  
  METHODS
  Patients who sustained an open tibial fracture which underwent delayed soft tissue coverage between January 2002 and December 2007 were included. Exclusion criteria included open fractures receiving a combination of NPWT and conventional dressings, fractures which were treated with a primary amputation, and fractures associated with mortality.
  
  
  METHODS
  : NPWT with reticulated open cell foam or conventional dressings at surgeon's discretion.
  
  
  METHODS
  Deep infection rate.
  
  
  RESULTS
  A total of 229 open tibial fractures in 220 patients met the inclusion criteria and received either NPWT (166/229-72%) or conventional dressings (63/229-28%). There was a decreased rate of deep infection in the NPWT group compared with the conventional dressing group [8.4% (14/166) vs. 20.6% (13/63); P = 0.01]. Univariate predictors of deep infection included Gustilo type {odds ratio (OR): 3.13 [95% confidence interval (CI): 1.74-5.64]; P < 0.001} and use of NPWT [OR: 0.35 (95% CI: 0.16-0.80); P = 0.01]. When adjustment was performed for Gustilo type with multivariate analysis, use of NPWT was found to reduce the risk of deep infection by almost 80% [OR: 0.22 (95% CI: 0.09-0.55); P = 0.001].
  
  
  CONCLUSIONS
  These results suggest that NPWT reduces the rate of deep infection when used for the dressing of traumatic wounds in open tibial fractures.
