Background/aim: Surgical site infection (SSI) is a severe complication of spinal surgery, which typically results in prolonged length of hospital stay, an increased number of revision surgeries, re-hospitalizations, worse clinical functional outcomes, and increased healthcare costs. The aim of the present study was to analyse if the duration of surgery can predict the spectrum of pathogens causing SSI in orthopaedic spine surgery.
Patients And Methods: We conducted a retrospective study over a period of two years at the University Hospital of Cologne in which all patients with postoperative surgical site infections were included.
