This article revealed a previously unknown mode of implant failure after spine surgery. The investigation of the prevalence of chronic deep implant infection in patients revised for pain after spinal fusion is substantial. This, when combined with available evidence from Agarwal, et al, supports the researchers’ theory behind the cause of implant failure, that there is “a hidden prevalence of sub-clinical germ colonization on the implant could be an underlying mechanism in [pedicle screw] PS loosening.” As demonstrated in results of the two-staged approach to this research, the pedicle screws are being contaminated in two phases: preoperative phase and intraoperative phase, both of which could be mitigated by employing newer methodologies or standards of care.
