Of these, 55 cases of primary open fracture were sutured in the first stage; 32 cases underwent internal fixation after primary debridement at the time of trauma. The patients were treated with surgical debridement, removal of internal fixation, and fixation with an external fixation frame. After debridement, those with local wounds that could not be completely closed and were complicated with exposed bone were randomly selected for either VSD covering treatment (study group, n=46) or bone cement covering treatment (control group, n=41. The distribution of pathogenic bacteria, surgical indicators, inflammatory factors [tumor necrosis factor\u2043\u03b1(TNF\u2043\u03b1), interleukin\u20436 (IL\u20436), and C\u2043reactive protein (CRP) levels], functional recovery [knee, ankle, and limb function recovery], and complications were summarized.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were 87 pathogenic bacteria strains in 87 patients, including 43 Gram\u2043positive bacteria strains (49.42%), 32 Gram\u2043negative bacteria strains (36.78%), and 12 fungi strains (13.80%). The number of dressing changes in the study group was less than that in the control group. The infection control time, wound sterility time, hospitalization time, and skin flap transfer operation time in the study group were shorter than those in the control group and the difference was statistically significant (P&amp;lt;0.05). After treatment, the levels of TNF\u2043\u03b1, IL\u20436, and CRP in the two groups decreased, among which the change in the study group was the most significant and the difference between the two groups was statistically significant (P&amp;lt;0.05). After treatment, the Hospital for Special Surgery Knee Score and Baird\u2013Jackson score of the two groups increased, among which the change in the study group was the most significant and the difference between the two groups was statistically significant (P&amp;lt;0.05). The excellent and good rate of the study group (95.65%) was higher than the excellent and good rate of the control group (80.49%) and the difference was statistically significant (P&amp;lt;0.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>When a wound cannot be closed, VSD treatment of patients with secondary bone infection after internal fixation of tibial fracture can improve the level of surgical indicators and inflammatory factor levels in patients, and promote the recovery of patients\u2019 limb function, and is thus worthy of clinical promotion and application.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fcimb.2024.1508424","type":"journal-article","created":{"date-parts":[[2025,1,17]],"date-time":"2025-01-17T05:10:28Z","timestamp":1737090628000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Impact of VSD therapy on surgical outcomes, inflammatory markers, and functional rehabilitation in patients with secondary bone infection following tibial fracture surgery"],"prefix":"10.3389","volume":"14","author":[{"given":"Sheng","family":"Chang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zengshan","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,1,17]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"429","DOI":"10.1016\/j.ijantimicag.2018.11.023","article-title":"Treatment of chronic osteomyelitis with multidose oritavancin: A case series and literature review","volume":"53","author":"Chastain","year":"2019","journal-title":"Int.
