The posterior-only approach is effective but requires 4\u20136 weeks of antibiotic treatment postoperatively. We hypothesized that AIBG used in an all-posterior approach could enhance infection control and shorten the postoperative course of PDVO.Methods: Thirty patients with PDVO of the lumbar or thoracic spine treated with transforaminal interbody debridement and fusion (TIDF) with AIBG between March 2014 and May 2022 were reviewed (AIBG group). For comparative analysis, 28 PDVO patients who underwent TIDF without AIBG between January 2009 and June 2011 were enrolled (non-AIBG group). The minimum follow-up duration was 2 years. Clinical characteristics and surgical indications were comparable in the two groups. C-reactive protein (CRP) levels and the postoperative antibiotics course were compared between the two groups.Results: Surgical treatment for PDVO resulted in clinical improvement and adequate infection control. Despite the shorter postoperative intravenous antibiotic duration (mean: 19.0 days vs. 39.8 days), the AIBG group had significantly lower CRP levels at postoperative 4 and 6 weeks. The mean Visual Analog Scale pain scores improved from 7.3 preoperatively to 2.2 at 6 weeks postoperatively. The average angle correction at the last follow-up was 7.9\u00b0.Conclusions: TIDF with AIBG for PDVO can achieve local infection control with a faster reduction in CRP levels, leading to a shorter antibiotic duration.<\/jats:p>","DOI":"10.31616\/asj.2024.0388","type":"journal-article","created":{"date-parts":[[2025,1,20]],"date-time":"2025-01-20T07:38:42Z","timestamp":1737358722000},"page":"38-45","update-policy":"https:\/\/doi.org\/10.31616\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Transforaminal
