Vacuum sealing drainage (VSD) is widely used in adult osteomyelitis, but evidence in children remains limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective cohort study included 55 consecutive children with AHO treated surgically between November 2019 and May 2025. Twenty-five patients underwent debridement plus VSD (VSD group), and 30 underwent debridement alone (control group). Baseline demographics, clinical characteristics, laboratory findings, and surgical details were collected. The primary outcome was length of hospital stay; secondary outcomes included number of surgical procedures, intravenous antibiotic duration, and infection recurrence within 3 months. Inverse probability of treatment weighting (IPTW) was applied to address confounding.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Before adjustment, VSD was associated with significantly longer hospital stay (33.2\u2009\u00b1\u200919.3 vs. 21.0\u2009\u00b1\u20099.5 days,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.003) and a greater number of surgical procedures (3.6\u2009\u00b1\u20091.5 vs. 1.0\u2009\u00b1\u20090,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.001) compared with controls. No significant differences were observed in intravenous antibiotic duration (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.51), superinfection rate (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.45), or 3-month recurrence (0% in both groups). After IPTW, all covariates were well balanced (SMD\u2009&amp;lt;\u20090.1), and the effect estimates remained essentially unchanged: VSD remained associated with longer hospitalization (mean difference: 10.1 days;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.009) and more procedures (mean difference: 2.5;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.001).
