BackgroundThe risk of wound-related complications, including surgical site infections (SSIs), in patients undergoing surgery for metastatic spine disease (MSD) is high. Consequently, patients requiring wound revision surgery face delay in resuming oncological care and incur additional hospitalization. Recent reports suggest that negative pressure wound therapy (NPWT) applied on a closed wound at the time of surgery significantly reduces postoperative wound complications in degenerative spine disease and trauma setting. Here, we report a single institution experience with incisional NPWT in patients undergoing surgery for MSD.MethodsWe compared rates of wound complications requiring surgical revision in a surgical cohort of patients with or without NPWT from 2015 to 2020. Adult patients with radiographic evidence of MSD with mechanical instability and/or accelerated neurological decline were included in the study. NPWT was applied on a closed wound in the operating room and continued for 5 days or until discharge, whichever occurred first.ResultsA total of 42 patients were included: 28 with NPWT and 14 without. Patient demographics including underlying comorbidities were largely similar. NPWT patients had higher rates of prior radiation to the surgical site (36% vs. 0%, P = 0.017) and longer fusion constructs (6.7 vs. 3.9 levels, P < 0.001). Three patients (21%) from the control group and none from the NPWT group contracted SSI requiring wound washout (P = 0.032).ConclusionsOur data suggest that SSI and wound dehiscence are significantly reduced with the addition of incisional NPWT in this vulnerable population.Copyright © 2021 Elsevier Inc.
