Impact of Plastic Surgery and an Enhanced Prophylaxis Protocol on Cervical Spine Surgery Infection. Plast Surg (Oakv) 2024; 32:445-451. [PMID: 39104945 PMCID: PMC11298146 DOI: 10.1177/22925503221120542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 05/24/2022] [Accepted: 06/07/2022] [Indexed: 08/07/2024] Open
Abstract
Background: Reduction of surgical site infections (SSIs) is important in improving cervical spine surgery outcomes. Plastic surgery involvement and an enhanced modified prophylaxis protocol may reduce infection rates. Methods: A total of 962 cervical spine operations were conducted by a single surgeon (TFC). An enhanced modified prophylaxis protocol and plastic surgery were used in some operations. Differences in infection rates, surgical approach, previous operations, prophylaxis use, and plastic surgery involvement were compared using Fisher's exact tests and multivariate linear regression. Results: Four patients (0.42%) experienced SSIs. All 4 infections involved the standard protocol, posterior approach, and did not involve plastic surgery. The infection rate was lower in the enhanced protocol group when compared to the standard protocol (β -0.78, 95% CI -1.23 to -0.33, P = .0008). The enhanced protocol group had an increased percentage of operations with plastic surgery (β 0.19, 95% CI 0.10 to 0.28, P < .0001). The infection rate among the plastics group was 0.00% compared to 0.60% for the non-plastics group (P = .32). The plastics group had a lower rate of anterior approach when compared to the non-plastics group (β -0.20, 95% CI -0.24 to -0.15, P = .049). Among the posterior approach group, procedures with plastic surgery had an infection rate of 0.00% compared to 2.53% without plastic surgery (P = .13). Conclusion: The enhanced protocol was associated with a lower SSI rate and increased plastic surgery involvement. Posterior approaches were associated with increased infection rates and the likelihood of utilizing plastic surgery. Both the enhanced protocol and plastic surgery may decrease infection.

Abstract
STUDY DESIGN Observational Study. OBJECTIVES Surgical site infections (SSIs) are one of the major complications in spine surgery. Numerous factors that increase the risk of SSI have been widely described. However, clinical guidelines on antibiotic prophylaxis are usually common for all patients. There are no specific guidelines for patients with a high risk of infection. The aim of this paper is to create a specific protocol for patients at high risk of SSI. METHODS This is a three-cohort study using a prospective database. Risk patients are those who meet at least two of the following criteria: obesity, diabetes, reoperation and immunosuppression. Between October 2021 and April 2023, 132 patients were recruited.They were divided into three cohorts: cohort A, 46 patients, standard prophylaxis with cefazolin 2 g/8 h for 24 h; cohort B, 46 patients, cefazolin 2 g/8h and amikacin 500 mg/12 h for 24 h; cohort C, 40 patients, cefazolin 2 g/8h and amikacin 500 mg/12 h for 72 h. RESULTS There was a significant decrease in the infection rate depending on the prophylaxis (23.9% in cohort A, 8.7% in cohort B, and 2.5% in cohort C). When logistic regression models were applied and cohorts B and C were compared with A, the following results were obtained: OR of 0.30 (CI: 0.08 - 0.97; P = 0.057) and 0.08 (IC: 0.00 - 0.45; P = 0.019), respectively. CONCLUSIONS Prophylaxis with prolonged double antibiotic therapy with cefazolin and amikacin is associated with a statistically significant decrease in the rate of SSI in patients with a high risk of infection.

Abstract
Background Patients with poor glycemic control are at increased risk of postoperative complications. Hemoglobin A1c (HbA1c) has traditionally been used to assess preoperative glycemic control, but with limitations. More recently, fructosamine has been tested preoperatively in patients undergoing elective total joint arthroplasty. This study aims to assess whether preoperative serum fructosamine can be used to avoid adverse outcomes in patients undergoing foot and ankle surgery. Methods This was a retrospective chart review of all patients who underwent foot and ankle surgeries at 2 level 1 trauma centers from January 2020 to December 2021. Of those, 305 patients were tested for HbA1c and fructosamine levels preoperatively. Adverse outcomes were assessed over 30 and 90 days. Outcomes of interest were surgical site infection, wound dehiscence, unplanned return to the operating room, unplanned readmission, and death. Data were analyzed using independent 2-sample t tests. A mixed effects model was used for multivariate analysis. P values less than .05 were considered statistically significant. Results Preoperative serum fructosamine was significantly higher (P = .029) in those with complications within 90 days compared to those without. The mean preoperative fructosamine level was 269.2 µmol/L (SD = 58.85) in those who did have a complication vs 247.2 µmol/L (SD = 53.95) in those who did not. Clinically significant fructosamine threshold was determined using 2 different methods. Fructosamine was found to be non-inferior to HbA1c in accurately predicting postoperative complications. Conclusion Fructosamine is a serum marker that reflects nearer term glycemic control than HbA1c. Elevation in preoperative fructosamine is associated with increased perioperative complications after foot and ankle surgery within 90 days. Preoperative fructosamine may be used in patient optimization and risk stratification when determining candidacy and timing for elective foot and ankle surgeries. Level of evidence Level III, retrospective cohort study.

Synthesis and evaluation of a novel vancomycin-infused, biomimetic bone graft using a rat model of spinal implant-associated infection. NORTH AMERICAN SPINE SOCIETY JOURNAL 2024; 18:100323. [PMID: 38746017 PMCID: PMC11091687 DOI: 10.1016/j.xnsj.2024.100323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 04/05/2024] [Accepted: 04/06/2024] [Indexed: 05/16/2024]
Abstract
Background Postoperative infection is a complication of spinal fusion surgery resulting in increased patient morbidity. Strategies including intraoperative application of powdered vancomycin have been proposed to reduce the incidence of infection; however, such antimicrobial effects are short-lived. Methods Instrumentation of the L4-L5 vertebrae was performed mimicking pedicle screw and rod fixation in 30 rats. Titanium instrumentation inoculated with either PBS or 1×105 CFU bioluminescent MRSA, along with biomimetic bone grafts infused with varying concentrations of vancomycin and 125 µg of rhBMP-2 (BioMim-rhBMP-2-VCM) were implanted prior to closure. Infection was quantified during the six-week postoperative period using bioluminescent imaging. Arthrodesis was evaluated using micro-CT. Results Infected animals receiving a bone graft infused with low-dose (0.18 mg/g) or high-dose vancomycin (0.89 mg/g) both exhibited significantly lower bioluminescent signal over the six-week postoperative period than control animals inoculated with MRSA and implanted with bone grafts lacking vancomycin (p=.019 and p=.007, respectively). Both low and high-dose vancomycin-infused grafts also resulted in a statistically significant reduction in average bioluminescence when compared to control animals (p=.027 and p=.047, respectively), independent of time. MicroCT analysis of animals from each group revealed pseudoarthrosis only in the control group, suggesting a correlation between infection and pseudoarthrosis. MRSA-inoculated control animals also had significantly less bone volume formation on micro-CT than the PBS-inoculated control cohort (p<.001), the MRSA+low-dose vancomycin-infused bone graft cohort (p<.001), and the MRSA+high-dose vancomycin-infused bone graft cohort (p<.001). Conclusion BioMim-rhBMP-2-VCM presents a novel tissue engineering approach to simultaneously promoting arthrodesis and antimicrobial prophylaxis in spinal fusion. Despite mixed evidence of potential osteotoxicity of vancomycin reported in literature, BioMim-rhBMP-2-VCM preserved arthrodesis and osteogenesis with increasing vancomycin loading doses due to the graft's osteoinductive composition.

Abstract
BACKGROUND CONTEXT Surgical site infections (SSI) are one of the common complications following spinal fusion surgery. Unfortunately, several studies had shown conflicting results regarding optimal timing of surgical antimicrobial prophylaxis (SAP) administration. Due to limitations in population homogeneity and sample size, these studies have not provided significant statistical correlations or clear practical recommendations. PURPOSE The purpose of the study was to investigate the impact of timing of cefuroxime SAP on the risk of SSI in patients undergoing spinal fusion surgery, and to determine the optimal timing of administration. DESIGN Retrospective nested case-control study. PATIENT SAMPLE We retrospectively analyzed consecutive patients who underwent spinal fusion surgery at our institution between October 2011 and October 2021. OUTCOME MEASURE In the current study, the primary outcome measure was SSI. METHODS This was a retrospective nested case-control study. All consecutive patients who underwent spinal fusion surgery at our institution between October 2011 and October 2021 formed a retrospective cohort. For each SSI case, 2 controls free of SSI at the time of the index date of their corresponding case were selected, matched by age, sex, and calendar year. Electronic record and radiographic data were reviewed retrospectively in electronic database. SAP related data included timing of administration, preoperative dose, intraoperative second dose, and postoperative use. To examine the effects of mismatched variables, we further adjusted for possible confounding factors using conditional logistic regression models. Subsequently, subgroup analyses were conducted to assess the robustness of the statistical associations. RESULTS According to the preplanned statistical scheme and matching factors, we matched 236 controls for these SSI cases, and the subsequent statistical analysis was performed on these 354 patients. After adjusting for confounding factors, the results indicated that the risk of SSI was 70% higher in the group receiving SAP 31 to 60 minutes before incision compared to the group receiving SAP 0 to 30 minutes before incision (OR=1.732, 95%CI 1.031-2.910, p=.038). Additionally, the risk of SSI was 150% higher in the group receiving SAP 61 to 120 minutes before incision compared to the group receiving SAP 0 to 30 minutes before incision (OR=2.532, 95%CI 1.250-5.128, p=.010). In subgroup analysis, this statistical trend persisted for both deformity surgeries and different SSI classifications. CONCLUSION Administering cefuroxime SAP within 30 minutes before skin incision significantly reduces the risk of SSI, whether they are deep or superficial, in spinal fusion surgery. This pattern remains consistent among spinal deformity patients.

Abstract
PURPOSE The objective was to determine the efficacy of intraoperative vancomycin powder in preventing SSIs in neurological surgeries. METHODS A prospective randomized controlled study of patients who had clean cranial and non-implant spine surgeries at the Irrua Specialist Teaching Hospital, Irrua, Nigeria from February 1, 2021 to January 31, 2022. Patients were randomized into two groups. Group A patients had prophylactic intraoperative vancomycin powder applied to the surgical bed before wound closure while group B patients did not. Patients in both groups were followed up for 30 days post-operatively for evidence of SSI. The occurrence of SSIs was determined using clinical and laboratory parameters. Baseline characteristics, operative details, rates of wound infection, and microbiological data for each case were recorded. Data was analyzed using Statistical Package for Scientific Solution (SPSS) version 23 software. RESULTS Forty-two patients were randomized into 2 groups of 21 patients each. The age range of the patients was 20 to 80 years. The majority of the patients were males (32 out of 42). The mean age of patients in group A was 48.05 ± 17.03 years, while group B had a mean age of 45.95 ± 19.14 years. The mean Body Mass Index of patients in groups A and B were 23.92 ± 5.21 and 23.21 ± 3.99 respectively. Seven out of 21 patients (33.3 %) in the control group ( group B) had superficial SSIs while no patient in the experimental group had SSI, p-value < 0.05. The organisms cultured were Klebsiella pneumoniae, Pseudomonas aeruginosa, and Staphylococcus aureus. CONCLUSION Intraoperative vancomycin powder was effective in reducing the rate of SSIs following neurological surgeries and without adverse drug reactions.

Abstract
OBJECTIVE To evaluate the global practice pattern of wound dressing use after lumbar fusion for degenerative conditions. METHODS A survey issued by AO Spine Knowledge Forums Deformity and Degenerative was sent out to AO Spine members. The type of postoperative dressing employed, timing of initial dressing removal, and type of subsequent dressing applied were investigated. Differences in the type of surgery and regional distribution of surgeons' preferences were analyzed. RESULTS Right following surgery, 60.6% utilized a dry dressing, 23.2% a plastic occlusive dressing, 5.7% glue, 6% a combination of glue and polyester mesh, 2.6% a wound vacuum, and 1.2% other dressings. The initial dressing was removed on postoperative day 1 (11.6%), 2 (39.2%), 3 (20.3%), 4 (1.7%), 5 (4.3%), 6 (0.4%), 7 or later (12.5%), or depending on drain removal (9.9%). Following initial dressing removal, 75.9% applied a dry dressing, 17.7% a plastic occlusive dressing, and 1.3% glue, while 12.1% used no dressing. The use of no additional coverage after initial dressing removal was significantly associated with a later dressing change (p < 0.001). Significant differences emerged after comparing dressing management among different AO Spine regions (p < 0.001). CONCLUSION Most spine surgeons utilized a dry or plastic occlusive dressing initially applied after surgery. The first dressing was more frequently changed during the first 3 postoperative days and replaced with the same type of dressing. While dressing policies tended not to vary according to the type of surgery, regional differences suggest that actual practice may be based on personal experience rather than available evidence.

EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2023; 32:4259-4264. [PMID: 37615727 DOI: 10.1007/s00586-023-07897-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 07/17/2023] [Accepted: 08/09/2023] [Indexed: 08/25/2023]
Abstract
PURPOSE It is unclear if intra-wound vancomycin powder significantly reduces the infection rate for uninstrumented spine surgery. The purpose of this study is to compare the rate of surgical site infection (SSI) in uninstrumented spine surgery that used vancomycin powder against controls. METHODS A search was performed on PUBMED/MEDLINE, Cochrane Database and Embase on 14 October 2022. Search keywords were "vancomycin, spine surgery, uninstrumented and spinal surgery." Instrumented cases were excluded. Type of surgery, type of treatment and incidence of infection among experimental or control were recorded. RESULTS 288 articles were obtained from a literature search. 16 studies met inclusion criteria. 6/16 studies that reported on the infection rate using vancomycin were obtained. There were 1376 control cases with 20 cases of post-operative infection (1.45% overall). There were 795 cases that received prophylactic intra-wound vancomycin powder with 10 cases of infection reported (1.26%). There was no significant difference in infections between cases that received vancomycin compared to control. On subgroup analysis, studies that had a high rate of infection (Strom and Cannon) had a significant difference on the rate of infection with the use of vancomycin compared to control. DISCUSSION AND CONCLUSION The current study was unable to conclude that vancomycin decreased the rate of surgical site infections. Vancomycin use may be useful in populations that have a high rate of infection. Limitations in this study include the small number of studies that report on the use of vancomycin on uninstrumented spine surgery.

Infect Dis Rep 2023; 15:717-725. [PMID: 37987402 PMCID: PMC10660755 DOI: 10.3390/idr15060064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 11/07/2023] [Accepted: 11/08/2023] [Indexed: 11/22/2023] Open
Abstract
This study evaluates potential associations between the perioperative urinary catheter (UC) carriage and (Gram-negative) surgical site infections (SSIs) after spine surgery. It is a retrospective, single-center, case-control study stratifying group comparisons, case-mix adjustments using multivariate logistic regression analyses. Around half of the patients (2734/5485 surgeries) carried a UC for 1 day (median duration) (interquartile range, 1-1 days). Patients with perioperative UC carriage were compared to those without regarding SSI, in general, and Gram-negative, exclusively. The SSI rate was 1.2% (67/5485), yielding 67 revision surgeries. Gram-negative pathogens caused 16 SSIs. Seven Gram-negative episodes revealed the same pathogen concomitantly in the urine and the spine. In the multivariate analysis, the UC carriage duration was associated with SSI (OR 1.1, 95% confidence interval 1.1-1.1), albeit less than classical risk factors like diabetes (OR 2.2, 95%CI 1.1-4.2), smoking (OR 2.4, 95%CI 1.4-4.3), or higher ASA-Scores (OR 2.3, 95%CI 1.4-3.6). In the second multivariate analysis targeting Gram-negative SSIs, the female sex (OR 3.8, 95%CI 1.4-10.6) and a UC carriage > 1 day (OR 5.5, 95%CI 1.5-20.3) were associated with Gram-negative SSIs. Gram-negative SSIs after spine surgery seem associated with perioperative UC carriage, especially in women. Other SSI risk factors are diabetes, smoking, and higher ASA scores.

Spine J 2023; 23:1580-1585. [PMID: 37473810 DOI: 10.1016/j.spinee.2023.07.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 07/03/2023] [Accepted: 07/16/2023] [Indexed: 07/22/2023]
Abstract
BACKGROUND CONTEXT Surgical site infection (SSI) following lumbar surgery can increase healthcare costs and lead to poor clinical outcome. Irrigation of wounds with saline solution is widely accepted globally and safe for nearly all kinds of surgery. However, the efficacy of different volumes of wound irrigation has not been addressed in elective spine surgery. The role and the optimal amount of intraoperative wound saline irrigation in preventing SSI in clean spinal surgery remain unclear. PURPOSE We aimed to investigate if insufficient intraoperative irrigation may be a risk factor for postoperative SSI. Additionally, we investigated the optimal amount of normal saline (NS) for irrigation to prevent postoperative SSI. STUDY DESIGN This is a retrospective study of patients with degenerative spinal stenosis who were treated surgically. Patients were grouped according to the amount of intra-wound irrigation during surgery. PATIENT SAMPLE We included 444 patients with degenerative lumbar spinal conditions who had undergone one to five level open spinal fusion surgeries from January 2015 through April 2020. OUTCOME MEASURES The definition of superficial or deep SSI in this study was based on the Centers for Disease Control and Prevention criteria for SSI. The fusion status accessed was based on the Bridwell grading system at the final follow-up. Self-reported and clinical outcome measures include visual analog scale and Oswestry Disability Index. METHODS A total of 193 patients underwent irrigation with a bulb syringe with manual method (B group) with 2,000 mL NS; 251 patients underwent interpulse battery-powered device irrigation (P group) with >6,000 mL NS. Based on our protocolized departmental guidelines, all patients received the same preoperative preparation and standard surgical steps and postoperative care plan. Patients' demographic and surgical parameters were recorded. The main outcome measures included superficial wound infection, deep infection and overall infection. RESULTS The incidence of overall SSI was 4.66% in the B group and 1.59% in the P group. The univariate analysis revealed a significant correlation with DM and irrigation amount per hour during surgery but not age, BMI, smoking, operative duration, fusion level, or blood loss. We determined the optimal irrigation amount during surgery as 1,400 mL per hour based on the receiver operating characteristic (ROC) curve (sensitivity, 92.3%; specificity, 44.1%). This was statistically significant (p=.033) with an odds ratio of 9.284 (95% confidence interval 1.2-72.0). In the analysis of surgical factors, the infection group had a significantly lower irrigation amount during surgery. To summarize, patients with diabetes and those receiving less than 1,400 mL of NS/hour had a higher likelihood of developing SSI. CONCLUSIONS We observed that diabetes and lower volume of intraoperative irrigation were both risk factors for postoperative SSI following degenerative lumbar spine surgery. To reduce SSI in lumbar spine surgery, intra-wound irrigation with more than 1,400 mL/h of NS was recommended.

[PMID: 37355045 DOI: 10.1016/j.spinee.2023.06.392] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 06/07/2023] [Accepted: 06/17/2023] [Indexed: 06/26/2023]
Abstract
BACKGROUND CONTEXT Psoriasis is a chronic, autoimmune disease of the skin that affects approximately 3% of the US adult population. Patients with psoriasis may be predisposed to spine surgical site infections (SSI) related to the condition and/or related medications following surgeries such as lumbar laminotomy/discectomy. PURPOSE To assess the potential correlation of psoriasis and its related treatment medications on the risk of infection-related complications after lumbar laminotomy/discectomy. STUDY DESIGN Retrospective case control, national administrative database study. PATIENT SAMPLE Adult patients who underwent isolated single-level lumbar discectomy between 2010 and Q1 of 2021 were identified in the PearlDiver Mariner Ortho151 national administrative database (excluding those with concurrent diagnoses of fractures, neoplasms, or infections). OUTCOME MEASURES Ninety-day postoperative rates of surgical site infection and sepsis. METHODS Lumbar laminotomy/discectomy patients with versus without psoriasis were matched 1:4 based on age, sex, and Elixhauser Comorbidity Index. The risk of SSI and sepsis in the 90-day postoperative window between the cohorts were compared with multivariable analyses. Five-year reoperation rates were also compared with log rank test. The matched psoriasis cohort was further subdivided by psoriasis treatment regimens - no medication treatment (NT), topical therapies only (TT), topical therapies with oral systemic treatments (TT/OS), and topical therapies with biologics (TT/B). Multivariable logistic regression was used to assess the risk of SSI and sepsis within 90 days after lumbar laminotomy/discectomy for each treatment subgroup compared to patients without psoriasis. RESULTS In total, 2,262 patients with psoriasis who underwent single-level lumbar laminotomy/discectomy were identified and matched by age, sex, and Elixhauser Comorbidity Index to 9,044 patients without psoriasis. Multivariable logistic regression showed that, compared to the patients without psoriasis, patients with psoriasis had a 1.795 times higher chance of developing SSI (odds ratio [OR]) (p<.001) and sepsis (OR: 1.743, p=.027) within 90 days of surgery. Having psoriasis did not significantly correlate with 5-year reoperation rates. Of those with psoriasis, NT subcohort had 1,038 patients, TT subcohort 571 patients, TT/OS subcohort 226 patients, and TT/B subcohort 140 patients. Based on multivariable analysis and compared to nonpsoriasis patients, those in the NT, TT, TT/OS were not at greater odds of postoperative SSI or sepsis. Conversely, those in the TT/B subcohort were at significantly greater odds of SSI (OR: 3.102, p=.019) and sepsis (OR: 6.367, p=.027). CONCLUSIONS Of single-level lumbar laminotomy/discectomy patients with psoriasis, only those on topical therapies and biologics were at greater risk of postoperative SSI and sepsis. This subcohort warrants specific attention when undergoing lumbar laminotomy/discectomy and possibly holding such medications for a period prior to surgery may be warranted if possible.

Abstract
Early postoperative infections can affect a significant number of spinal surgery patients. Many studies reported on the features that may associate with elevated risk of infectious complications in this group. Data on the impact of glucose metabolism disorders in this area are well known. At the same time information on the correlation of preoperative HbA1c level and postoperative infections in spinal surgery are still scarce. Furthermore there are no strict recommendations regarding routine HbA1c testing prior to elective surgery. In present SR we aimed to report available clinical evidence on association between preoperative HbA1c and early postoperative infections. We used PubMed and EMBASE database and a set of specific key words (spine surgery AND infections AND HbA1c) to identify eligible studies. The study was registered in PROSPERO database and reported according to PRISMA recommendations. 16 studies were selected for further assessment. Predominance of data indicated a significant correlation between preoperative HbA1c concentration and elevated risk of postoperative infections, as well as higher rate of non - infective complications and worse patients future outcome. Adequately designed future studies on purposely dimensioned sample size are needed to confirm the role of preoperative HbA1c testing in preoperative management of spinal surgery patients.

Abstract
PURPOSE Postoperative surgical site infection in patients treated with lumbosacral fusion has usually been thought to be caused by perioperative contamination. With the proximity of these incisions to the perineum, this study sought to determine if contamination by gastrointestinal and/or urogenital flora should be considered as a major cause of this complication. METHODS We conducted a retrospective review of adults treated with open posterior lumbosacral fusions between 2014 and 2021 to identify common factors in deep postoperative infection and the nature of the infecting organisms. Cases of tumor, primary infection and minimally invasive surgery were excluded. RESULTS 489 eligible patients were identified, 20 of which required debridement deep to the fascia (4.1%). Mean age, operative time, estimated blood loss and levels fused were similar between both groups. The infected group had a significantly higher BMI. The mean time from primary procedure to debridement was 40.8 days. Four patients showed no growth, 3 showed Staphylococcus sp. infection (Perioperative Inside-Out) requiring debridement at 63.5 days. Thirteen showed infection with intestinal or urogenital pathogens (Postoperative Outside-In) requiring debridement at 20.0 days. Postoperative Outside-In infections led to debridement 80.3 days earlier than Perioperative Inside-Out infections (p = 0.007). CONCLUSIONS 65% of deep infections in patients undergoing open lumbosacral fusion were due to early contamination by pathogens associated with the gastrointestinal and/or urogenital tracts. These required earlier debridement than Staphylococcus sp. INFECTIONS There should be renewed focus on keeping these pathogens away from the incision during the early stages of wound healing.

Abstract
BACKGROUND Perioperative prophylactic antibiotic (PPA) use in spine surgery is known to reduce the rate of surgical site infections. In the past decade, several evidence-based guidelines have been published and surveillance systems to monitor the proper use of antimicrobials had been adapted by many institutes. OBJECTIVE To report the trends of PPA prescription in lumbar fusion surgeries nationwide in the Republic of Korea. METHODS This is a nationwide registry study. Using the population-based data from the Republic of Korea provided by the Korean Health Insurance Review and Assessment Service, data of all lumbar spinal fusion surgeries performed between 2010 and 2018 in adult patients (age ≥19 years) were reviewed. RESULTS The most frequently used antibiotics were first-generation cephalosporins, which accounted for 38.2 % of total PPA prescriptions and were prescribed in 58.96 % of lumbar fusion surgeries. A gradual increase in prescription trends was observed. The second most frequently used PPAs were second-generation cephalosporins, which showed decrease in use from 2016. The frequency of vancomycin prescriptions gradually increased over the observation period and showed an almost four-fold increase in 2018 compared to 2010. First- and second-generation cephalosporins were prescribed less frequently to patients with renal disease. CONCLUSION The pattern of PPA use has changed remarkably over the observation period. Furthermore, specific differences in PPA prescriptions were observed among patients with certain co-morbidities.

Abstract
STUDY DESIGN This is a retrospective cohort study. OBJECTIVE The aim was to evaluate differences in readmission rates, number of debridements, and length of antibiotic therapy when comparing bacterial gram type following lumbar spinal fusion infections. SUMMARY OF BACKGROUND DATA Surgical site infections (SSIs) after spinal fusion serve as a significant source of patient morbidity. It remains to be elucidated how bacterial classification of the infecting organism affects the management of postoperative spinal SSI. METHODS Patients who underwent spinal fusion with a subsequent diagnosis of SSI between 2013 and 2019 were retrospectively identified. Patients were grouped based on bacterial infection type (gram-positive, gram-negative, or mixed infections). Poisson regressions analyzed the relationship between the type of bacterial infection and the number of irrigation and debridement (I&D) reoperations, and the duration of intravenous (IV) antibiotic therapy. Significance was set at P <0.05. RESULTS Of 190 patients, 92 had gram-positive (G+) infections, 57 had gram-negative (G-) infections, and 33 had mixed (M) infections. There was no difference in 30 or 90-day readmissions for infection between groups (both P =0.051). Patients in the M group had longer durations of IV antibiotic treatment (G+: 46.4 vs. G-: 41.0 vs. M: 55.9 d, P =0.002). Regression analysis demonstrated mixed infections were 46% more likely to require a greater number of debridements ( P =0.001) and 18% more likely to require an increased duration of IV antibiotic therapy ( P <0.001), while gram-negative infections were 10% less likely to require an increased duration of IV antibiotic therapy ( P <0.001) when compared with G- infections. CONCLUSION Spinal SSI due to a mixed bacterial gram type results in an increased number of debridements and a longer duration of IV antibiotics required to resolve the infection compared with gram-negative or gram-positive infections. LEVEL OF EVIDENCE Level III.

Abstract
Purpose This work is aimed at determining the application value of platelet-rich plasma (PRP) therapy plus total knee arthroplasty (TKA) in traumatic arthritis (TA) of the knee. Methods A retrospective study was conducted on 78 cases of TA of the knee admitted between March 2021 and January 2022 to the Quanzhou First Hospital Affiliated to Fujian Medical University. Based on different treatment methods, 38 cases treated with TKA were assigned to the control group, and 40 cases intervened by PRP+TKA were included in the observation group. The operation time (OT), drainage volume (DV), total blood loss (TBL), incision inflammatory reaction rate, and grade A healing rate were recorded. Besides, preoperative and postoperative knee joint Hospital for Special Surgery (HSS) scores, knee joint pain assessed by visual analogue scale (VAS), knee joint range of motion (ROM), and bone metabolism parameters (osteocalcin (OST), total N-terminal propeptide of type I procollagen (tPINP), and β-isomerized C-terminal telopeptides (β-CTX)) were recorded. Results The observation group showed reduced postoperative DV and TBL than the control group (P < 0.05). The two cohorts differed insignificantly in OT, incision inflammatory response rate, and grade A healing rate (P > 0.05). The observation group also had better improvement in the HSS score, pain VAS score, and knee ROM (P < 0.05). And higher postoperative OST and tPINP levels while lower β-CTX were determined in the observation group (P < 0.05). Conclusions PRP+TKA can validly improve the levels of bone metabolism markers in patients with TA of the knee and promote their knee functional recovery, with favorable safety.

Abstract
BACKGROUND Preoperative oral antibiotic use in patients undergoing foot and ankle surgery is standard practice, but no consensus has been reached regarding the efficacy of postoperative oral antibiotics. The purpose of this study was to determine whether postoperative oral antibiotics reduce the rate of surgical site infections (SSIs) in patients, with and without comorbidities, undergoing foot and ankle surgery. METHODS A retrospective chart review was conducted identifying patients who underwent foot and ankle surgery by 4 fellowship-trained, foot and ankle orthopaedic surgeons between January 1, 2015, and January 1, 2019. Patients were divided into 2 groups: those who received postoperative oral antibiotics (group 1) and those who did not (group 2). Two surgeons routinely prescribed postoperative oral antibiotics, and 2 did not. Demographics, comorbidities, and procedure complexity based on surgical site and Current Procedural Terminology code were recorded from the charts. The primary outcome was postoperative infection (superficial or deep) within 6 months after surgery. Patients with antibiotic use prior to surgery, preoperative infection, or lack of follow-up >6 weeks were excluded. Multivariate logistic regression modeling was used to analyze differences in infection rate and severity. RESULTS Chart review identified 3631 patients, 1227 of whom did not receive postoperative oral antibiotics whereas 2394 patients did. Routine postoperative oral antibiotic use did not significantly affect postoperative infection rates or severity. However, all covariates studied (diabetes, hypertension, obesity, tobacco use, alcohol use, rheumatoid conditions, and age) influenced postoperative infection rates and severity. CONCLUSION The results of this study indicate that postoperative oral antibiotics are not associated with differences in infection rates or severity. We do not recommend routine use in foot and ankle surgery.

Abstract
OBJECTIVE To clarify the influence of obstructive sleep apnea (OSA) on postoperative cognitive dysfunction (POCD) in elderly patients undergoing joint replacement. METHODS This study retrospectively enrolled130 patients who underwent joint replacement in the Department of Orthopaedics of Taizhou Municipal Hospital between January 2019 and March 2021 for analysis. According to polysomnography (PSG) results, 80 patients without OSA were included in group A and 50 with OSA were assigned to group B. The two groups were compared with respect to the following items: surgical indications (length of stay (LOS), intraoperative blood loss (IBL) and operation time (OT), incidence of postoperative delirium (POD), postoperative cognitive function (Mini-mental State Examination, MMSE), neurological function recovery (National Institutes of Health Stroke Scale, NIHSS) and (Scandinavian Stroke Scale, SSS)), mental health (Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS)), compliance, overall response rate (ORR), complications and patient satisfaction. RESULTS The LOS and OT were shorter, and the IBL was less in group A compared with those in group B. Group A also showed reduced NIHSS and SSS scores as well as SAS and SDS scores when compared with group B. In addition, lower incidence of POD, and higher compliance, ORR and satisfaction were observed in group A than in group B. In terms of cognitive function, although the MMSE score in both groups decreased after surgery, patients in group B had a lower MMSE score and a milder form of POCD. CONCLUSIONS OSA may affect the postoperative cognitive function and adversely influence the treatment outcome of elderly patients undergoing joint replacement.

Abstract
BACKGROUND Immediate-use steam sterilization (IUSS), formerly termed "flash" sterilization, has been historically used to sterilize surgical instruments in emergency situations. Strict guidelines deter its use, as IUSS has been theorized to increase the risk of surgical site infections (SSIs), leading to increased health-care costs and poor patient outcomes. We sought to examine the association between the use of IUSS and the rate of orthopaedic SSIs. METHODS The cases of 70,600 patients who underwent orthopaedic surgery-total knee or hip arthroplasty, laminectomy, or spinal fusion-from January 2014 to December 2020, were retrospectively reviewed for IUSS use. Of this group, 3,526 patients had had IUSS used during surgery. A propensity score-matched (PSM) analysis was conducted to account for known predictors of SSIs and included a total of 7,052 patients. The risk difference (RD), relative risk (RR), odds ratio (OR), and McNemar test compared the SSI risk for patients whose procedure had included the use of IUSS and those whose procedure had not included IUSS. RESULTS After propensity score matching, 111 (1.57%) of the 7,052 matched patients developed an SSI. Of the 111 patients, 61 (54.95%) were in the IUSS group and 50 (45.05%) were in the non-IUSS group. The estimated probability for developing an SSI was 1.42% for the patients in the non-IUSS group versus 1.73% for the patients in the IUSS group (RR = 0.82 [95% confidence interval (CI)]: 0.57 to 1.19], RD = -0.3% [95% CI: -0.9% to 0.27%]).There was no evidence that the proportion of SSI was greater in the IUSS group (McNemar test, p > 0.29). CONCLUSIONS SSI rates were not significantly different between IUSS and non-IUSS patients undergoing orthopaedic surgery. Future prospective studies are warranted to further explore the utility of IUSS during orthopaedic procedures. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
OBJECTIVE Since 2002, France has adopted the Patients' Rights Law, an alternative malpractice scheme creating a faster, less expensive out-of-court settlement ensuring compensation even in the absence of fault. We aimed to describe the implications of this system by analyzing 5 years of claims for infections related to spinal surgeries collected by the main insurer of French spine surgeons. METHODS We retrospectively analyzed 98 anonymized malpractice claims from 2015 to 2019 (20% of overall claims), including anonymized medical records of the patients, reports of the independent experts, final judgments, and entities supporting the compensation if any. RESULTS Claims included 8 deaths and 17 newly acquired neurological sequelae. The conclusions identified 22 faulty cases. The most frequent fault was a delay in diagnosis (10 cases), followed by inadequate surgical management (6 cases), inadequate antibiotic therapy (5 cases), and inadequate follow-up (1 case). Among the 67 cases (68.4%) proved not to be at fault, 10 were covered by the national solidarity fund because of their severity, and the remaining 57 were covered by hospitals. CONCLUSIONS Since the 2002 Patients' Rights Law, patients with postoperative infections have always received compensation. The out-of-court settlement offers the patients incurring morbidities the assurance of faster compensation. Although certainly subject to selection criteria, this procedure is free and does not necessitate the presence of a lawyer. The analysis of expert reports and the resulting court decisions imply prevention, anticipation, and collaboration of all health care providers and open an opportunity to improve their practices to limit these crucial followings.

Abstract
BACKGROUND The risk of surgical site infections (SSIs), particularly methicillin-resistant Staphylococcus aureus (MRSA) SSIs, after spinal surgeries is one of the most daunting experiences to patients and surgeons. Some authors suggest applying vancomycin powder on the wound before skin closure to minimize the risk of SSIs; however, this practice is not supported by well-established evidence. This study sought to assess the effectiveness of topical (i.e. intra-wound) vancomycin in minimizing the risk of SSIs in patients who underwent spinal surgeries at a Saudi hospital. METHODS A retrospective cohort study was conducted using the hospital database. Patients who underwent spinal surgeries from the period of 09/2013 to 09/2019 were included and followed up (observed from the time of the surgery) to 30 days (surgeries without implants) or 90 days (with implants). The odds ratio (OR) of the primary outcome between vancomycin treated versus non-treated patients was estimated using a logistic regression model adjusting for the measured confounders. A sensitivity analysis was conducted using propensity score analysis (inverse probability of treatment weighting [IPTW] with stabilized weights) to control for confounding by indication. All study analyses were completed using RStudio Version 1.2.5033. RESULTS We included 81 vancomycin treated vs. 375 untreated patients with 28 infections (8/81 vs. 20/375; respectively). The adjusted OR of SSIs between the two groups was 0.40 (95% confidence interval [CI] 0.11 to 1.34). The result of the propensity score analysis was consistent (OR: 0.97 [95% CI 0.35 to 2.68]). CONCLUSIONS We could not find a lower association of SSIs with intra-wound vancomycin in patients who underwent spinal surgeries. Further studies are needed to assess benefits of using topical vancomycin for this indication vs. the risk of antimicrobial resistance.

Abstract
BACKGROUND Posterior cervical decompression and fusion (PCF) is a common procedure used to treat various cervical spine pathologies, but the 90-d outcomes following PCF surgery continue to be incompletely defined. OBJECTIVE To identify risk factors associated with 90-d readmission and reoperation following PCF surgery. METHODS Adults undergoing PCF from 2012 to 2020 were identified. Demographic and radiographic data, surgical characteristics, and 90-d outcomes were collected. Univariate analysis was performed using Student's t-test, chi square, and Fisher exact tests as appropriate. Multivariable logistic regression models with lasso penalty were used to analyze various risk factors. RESULTS A total of 259 patients were included. The 90-d readmission and reoperation rates were 9.3% and 4.6%, respectively. The most common reason for readmission was surgical site infection (SSI) (33.3%) followed by new neurological deficits (16.7%). Patients who smoked tobacco had 3-fold greater odds of readmission compared to nonsmokers (odds ratio [OR]: 3.48; 95% CI 1.87-6.67; P = .0001). Likewise, the most common reason for reoperation was SSI (33.3%) followed by seroma and implant failure (25.0% each). Smoking was also an independent risk factor for reoperation, associated with nearly 4-fold greater odds of return to the operating room (OR: 3.53; 95% CI 1.53-8.57; P = .003). CONCLUSION Smoking is a significant predictor of 90-d readmission and reoperation in patients undergoing PCF surgery. Smoking cessation should be strongly considered preoperatively in elective PCF cases to minimize the risk of 90-d readmission and reoperation.

Abstract
BACKGROUND Use of a closed-incisional negative pressure therapy (ci-NPT) dressing is an emerging strategy to reduce surgical site infections (SSIs) in spine surgery that lacks robust data. OBJECTIVE To determine the impact of a ci-NPT, as compared with a standard dressing, on the development of SSIs after spine surgery. METHODS This was a prospective observational study over a 2-yr period. Indications for surgery included degenerative disease, deformity, malignancy, and trauma. Exclusion criteria included anterior and lateral approaches to the spine, intraoperative durotomy, or use of minimally invasive techniques. SSIs up to 60 d following surgery were recorded. RESULTS A total of 274 patients were included. SSI rate was significantly lower with ci-NPT dressing (n = 118) as compared with the standard dressing (n = 156) (3.4 vs 10.9%, P = .02). There was no statistical difference in infection rate for decompression alone procedures (4.2 vs 9.1%, P = .63), but there was a statistically significant reduction with the use of a negative-pressure dressing in cases that required instrumentation (3.2 vs 11.4%, P = .03). Patients at higher risk (instrumentation, deformity, and malignancy) had less SSIs with the use of ci-NPT, although this did not reach statistical significance. There were no complications in either group. CONCLUSION SSI rates were significantly reduced with a ci-NPT dressing vs a standard dressing in patients who underwent spinal surgery. The higher cost of a ci-NPT dressing might be justified with instrumented cases, as well as with certain high-risk patient populations undergoing spine surgery, given the serious consequences of an infection.

Abstract
OBJECTIVE The use of intrawound vancomycin powder in spine surgery has been shown to decrease the rate of surgical site infections; however, the optimal dose is unknown. High-dose vancomycin inhibits osteoblast proliferation in vitro and may decrease the rate of solid arthrodesis. Bone marrow-derived mesenchymal stem cells (BMSCs) are multipotent cells that are a source of osteogenesis in spine fusions. The purpose of this study was to determine the effects of vancomycin on rat BMSC viability and differentiation in vitro. METHODS BMSCs were isolated from the femurs of immature female rats, cultured, and then split into two equal groups; half were treated to stimulate osteoblastic differentiation and half were not. Osteogenesis was stimulated by the addition of 50 µg/mL l-ascorbic acid, 10 mM β-glycerol phosphate, and 0.1 µM dexamethasone. Vancomycin was added to cell culture medium at concentrations of 0, 0.04, 0.4, or 4 mg/mL. Early differentiation was determined by alkaline phosphatase activity (4 days posttreatment) and late differentiation by alizarin red staining for mineralization (9 days posttreatment). Cell viability was determined at both the early and late time points by measurement of formazan colorimetric product. RESULTS Viability within the first 4 days decreased with high-dose vancomycin treatment, with cells receiving 4 mg/mL vancomycin having 40%-60% viability compared to the control. A gradual decrease in alizarin red staining and nodule formation was observed with increasing vancomycin doses. In the presence of the osteogenic factors, vancomycin did not have deleterious effects on alkaline phosphatase activity, whereas a trend toward reduced activity was seen in the absence of osteogenic factors when compared to osteogenically treated cells. CONCLUSIONS Vancomycin reduced BMSC viability and impaired late osteogenic differentiation with high-dose treatment. Therefore, the inhibitory effects of high-dose vancomycin on spinal fusion may result from both reduced BMSC viability and some impairment of osteogenic differentiation.

Abstract
BACKGROUND In order to elucidate whether serum inflammatory markers identify patients with local surgical site infection(SSI) as underlying disease for recurrent or new symptomatology following spine surgery, we evaluated the diagnostic potential of interleukin-6(IL-6) as a marker of SSI. The diagnostic significance of IL-6 was compared to the standard serum inflammatory markers C-reactive protein(CRP) and white blood cell count (WBCC). METHOD Ninety-eight consecutive patients with readmission due to recurrent or new symptomology after spinal surgery of degenerative spine disorders entered the study. Baseline patients' characteristics and the abovementioned inflammatory markers were collected, and arithmetical means with standard deviation, area under the curve (AUC), thresholds, sensitivity, specificity, positive(+)likelihood ratio (LR), and negative(-)LR with corresponding 95% confidence interval(95%CI) were calculated and correlated with presence or absence of SSI. RESULTS Nine patients suffered from a SSI, whereas the remaining 89 patients had a recurrent/adjacent-segment degenerative disorder without evidence of infection. The most significant parameter for diagnosing a SSI was serum IL-6 (cut-off value > 15.3 pg/ml, AUC = 0.954, SE = 85.7%, SP = 97.3%), followed by CRP (cut-off value = 0.8 mg/dl, AUC = 0.916, SE = 88.9%, SP = 84.5%) CONCLUSIONS: In the case of recurrent or new symptomatology following spinal surgery, serum IL-6 has the highest diagnostic potential for diagnosing spinal SSI.

Abstract
BACKGROUND Surgical-site infection (SSI) after spine surgery leads to increased length of stay, reoperation, and worse patient quality of life. We sought to develop a web-based calculator that computes an individual's risk of a wound infection following thoracolumbar spine surgery. METHODS We performed a retrospective review of consecutive patients undergoing elective degenerative thoracolumbar spine surgery at a tertiary-care institution between January 2016 and December 2018. Patients who developed SSI requiring reoperation were identified. Regression analysis was performed and model performance was assessed using receiver operating curve analysis to derive an area under the curve. Bootstrapping was performed to check for overfitting, and a Hosmer-Lemeshow test was employed to evaluate goodness-of-fit and model calibration. RESULTS In total, 1259 patients were identified; 73% were index operations. The overall infection rate was 2.7%, and significant predictors of SSI included female sex (odds ratio [OR] 3.0), greater body mass index (OR 1.1), active smoking (OR 2.8), worse American Society of Anesthesiologists physical status (OR 2.1), and greater surgical invasiveness (OR 1.1). The prediction model had an optimism-corrected area under the curve of 0.81. A web-based calculator was created: https://jhuspine2.shinyapps.io/Wound_Infection_Calculator/. CONCLUSIONS In this pilot study, we developed a model and simple web-based calculator to predict a patient's individualized risk of SSI after thoracolumbar spine surgery. This tool has a predictive accuracy of 83%. Through further multi-institutional validation studies, this tool has the potential to alert both patients and providers of an individual's SSI risk to improve informed consent, mitigate risk factors, and ultimately drive down rates of SSIs.

Abstract
Over the last years the number of spine surgeries with instrumentation has grown to an indispensable column in the treatment for different pathologies of the spine. A further increase in the incidence of instrumented spinal surgery is expected throughout the next years. Although the implementation and development of new techniques offer faster and more minimal invasive procedures, shortening surgery time, reducing soft tissue injury and revision due to hardware misplacement, the incidence of postoperative spinal implant infections (PSII) remains high. PSII related complications and revision procedures pose an enormous socioeconomic burden. Therefore, standardized strategies and protocols for treatment of PSII are urgently needed. While in former times hardware exchange or hardware removal was common practise in the field of spine surgery this approach has changed over the last years. Although the evidence from clinical studies in the field of PSII is of limited evidence, critical variables for revision strategies of PSII have been identified. Further, to quickly advance in the field of PSII it is certainly important to extrapolate and learn using data regarding the management from other fields of prosthetic joint infections. This should include clinical as well as experimental work in particular in the context of the biofilm, sonication as well as microbiological concepts. Over the last years, at our institution standardized procedures for diagnostic, surgical as well as antimicrobial treatment have been developed, based on the latest recommendations in peer-reviewed literature and our own data. Here we give an overview about surgical revision strategies for PSII and discuss the key points of our standardized protocol.

Abstract
Background: Removal of hardware with irrigation and debridement in patients with surgical site infections (SSIs) is performed commonly. However, the removal of hardware from patients with SSIs after spinal procedures is controversial. Moreover, primary spinal infections such as spondylodiscitis may require instrumentation along with surgical debridement. The purpose of this article was to evaluate critically and summarize the available evidence related to retention of hardware in patients with deep SSIs, and the use of instrumentation in surgical treatment of primary spinal infections. Methods: A literature search utilizing PubMed database was performed. Studies reporting the management of deep SSIs after instrumented spinal procedures, and of primary spinal infections using instrumentation published in peer-reviewed journals were included. Identified publications were evaluated for relevance, and data were extracted from the studies deemed relevant. Results: Because SSIs occur typically during the early post-operative period before stable bony fusion has been achieved, the removal of instrumentation may be associated with instability of the spinal column, pseudarthrosis, progressive deformity, pain, loss of function, and deterioration in the activities of daily living (ADL). Hence, early SSIs after spinal instrumentation are usually treated without removal of hardware. Moreover, primary spinal infections such as spondylodiscitis may require surgical debridement and instrumentation in cases with associated instability. Conclusions: Retaining or using instrumentation in patients with SSIs after spinal procedures or in patients with primary spinal infections, respectively, are commonly practiced in the field of spine surgery. Further evidence is required for the development of definitive algorithms to guide spine surgeons in decision making regarding the fate of instrumentation in the treatment of spinal infections.
