Abstract
Abstract Aim Negative pressure wound therapy has frequently been used in a variety of surgical specialities, yet its effectiveness as a prophylactic therapy in spinal surgery remains unclear. A comprehensive systematic review and meta-analysis was performed, incorporating the most recent evidence, addressing this paucity in the literature. Method A systematic search of the literature from inception to June 2023 was conducted using the following databases: Ovid Medline, EMBASE, Cochrane Register of Controlled Trials (CENTRAL) and Web of Science. All included studies assessed primary wound closure for posterior spinal surgical incisions. Evidence was quality assessed and outcomes of interest were meta-analysed using odds ratios, comparing negative pressure wound therapy and standard dressing groups. Results Seven studies (n = 1319, mean age = 59.9 years, 55.8% male) were included. Patients with negative pressure dressings had a reduced risk of surgical site infection (odds ratio = 0.45, 95% CI 0.29 to 0.72, p < 0.001). Wound dehiscence approached significance favouring negative pressure dressings (odds ratio = 0.53, 95% CI 0.26 to 1.06, p = 0.07). Patients requiring a return to theatre for wound related complications showed no significant difference between groups (odds ratio = 0.66, 95% CI 0.37 to 1.18, p = 0.16). Conclusions Negative pressure wound therapy reduces the risk of surgical site infection in posterior spinal surgery patients. Given that surgical site infection in spine surgery is associated with significant morbidity and financial costs, implementation of prophylactic negative pressure wound therapy for this patient demographic may be beneficial.
