Fracture-related infection (FRI) is one of the most serious complications in orthopedic trauma surgery [1]. The role of Negative Pressure Wound Therapy (NPWT) remains controversial in the management pathway of FRI [2]. Currently, as scientific evidence is lacking, most recommendations for NPWT with respect to the treatment of FRI are based on expert opinion [3]. The aim of this study was to assess the influence of NPWT and its duration on recurrence of infection in operatively treated FRI patients. This is a retrospective cohort study based on the FRI database of three Level 1 Trauma Centres. To be included, patients had to be at least 16 years of age and needed to be surgically treated for FRI between January 1st 2015 and September 1st 2020. Included patients were subdivided in either the NPWT group, or in the control group, when no NPWT had been applied. To avoid confounding, patients were excluded if they (also) underwent NPWT prior to the FRI diagnosis. The relation between the duration of NPWT during FRI treatment and the recurrence rate of infection was analyzed using a multivariable logistic regression model.Aim
