    (Global spine journal, 2017-04) Hershman, Stuart H; Kunkle, William A; Kelly, Michael P; Buchowski, Jacob M; Ray, Wilson Z; Bumpass, David B; Gum, Jeffrey L; Peters, Colleen M; Singhatanadgige, Weerasak; Kim, Jin Young; Smith, Zachary A; Hsu, Wellington K; Nassr, Ahmad; Currier, Bradford L; Rahman, Ra'Kerry K; Isaacs, Robert E; Smith, Justin S; Shaffrey, Christopher; Thompson, Sara E; Wang, Jeffrey C; Lord, Elizabeth L; Buser, Zorica; Arnold, Paul M; Fehlings, Michael G; Mroz, Thomas E; Riew, K Daniel
    Multicenter retrospective case series and review of the literature.To determine the rate of esophageal perforations following anterior cervical spine surgery.As part of an AOSpine series on rare complications, a retrospective cohort study was conducted among 21 high-volume surgical centers to identify esophageal perforations following anterior cervical spine surgery. Staff at each center abstracted data from patients' charts and created case report forms for each event identified. Case report forms were then sent to the AOSpine North America Clinical Research Network Methodological Core for data processing and analysis.The records of 9591 patients who underwent anterior cervical spine surgery were reviewed. Two (0.02%) were found to have esophageal perforations following anterior cervical spine surgery. Both cases were detected and treated in the acute postoperative period. One patient was successfully treated with primary repair and debridement. One patient underwent multiple debridement attempts and expired.Esophageal perforation following anterior cervical spine surgery is a relatively rare occurrence. Prompt recognition and treatment of these injuries is critical to minimizing morbidity and mortality.

    Intrawound Vancomycin Decreases the Risk of Surgical Site Infection After Posterior Spine Surgery: A Multicenter Analysis.

    Study design

    Secondary analysis of data from a prospective multicenter observational study.

    Objective

    The aim of this study was to evaluate the occurrence of surgical site infection (SSI) in patients with and without intrawound vancomycin application controlling for confounding factors associated with higher SSI after elective spine surgery.

    Summary of background data

    SSI is a morbid and expensive complication associated with spine surgery. The application of intrawound vancomycin is rapidly emerging as a solution to reduce SSI following spine surgery. The impact of intrawound vancomycin has not been systematically studied in a well-designed multicenter study.

    Methods

    Patients undergoing elective spine surgery over a period of 4 years at seven spine surgery centers across the United States were included in the study. Patients were dichotomized on the basis of whether intrawound vancomycin was applied. Outcomes were occurrence of SSI within postoperative 30 days and SSI that required return to the operating room (OR). Multivariable random-effect log-binomial regression analyses were conducted to determine the relative risk of having an SSI and an SSI with return to OR.

    Results

    .: A total of 2056 patients were included in the analysis. Intrawound vancomycin was utilized in 47% (n = 966) of patients. The prevalence of SSI was higher in patients with no vancomycin use (5.1%) than those with use of intrawound vancomycin (2.2%). The risk of SSI was higher in patients in whom intrawound vancomycin was not used (relative risk (RR) -2.5, P < 0.001), increased number of levels exposed (RR -1.1, P = 0.01), and those admitted postoperatively to intensive care unit (ICU) (RR -2.1, P = 0.005). Patients in whom intrawound vancomycin was not used (RR -5.9, P < 0.001), increased number of levels were exposed (RR-1.1, P = 0.001), and postoperative ICU admission (RR -3.3, P < 0.001) were significant risk factors for SSI requiring a return to the OR.

    Conclusion

    The intrawound application of vancomycin after posterior approach spine surgery was associated with a reduced risk of SSI and return to OR associated with SSI.

    Rare Complications of Cervical Spine Surgery: Pseudomeningocoele.
    (Global spine journal, 2017-04) Ailon, Tamir; Smith, Justin S; Nassr, Ahmad; Smith, Zachary A; Hsu, Wellington K; Fehlings, Michael G; Fish, David E; Wang, Jeffrey C; Hilibrand, Alan S; Mummaneni, Praveen V; Chou, Dean; Sasso, Rick C; Traynelis, Vincent C; Arnold, Paul M; Mroz, Thomas E; Buser, Zorica; Lord, Elizabeth L; Massicotte, Eric M; Sebastian, Arjun S; Than, Khoi D; Steinmetz, Michael P; Smith, Gabriel A; Pace, Jonathan; Corriveau, Mark; Lee, Sungho; Riew, K Daniel; Shaffrey, Christopher
    This study was a retrospective, multicenter cohort study.Rare complications of cervical spine surgery are inherently difficult to investigate. Pseudomeningocoele (PMC), an abnormal collection of cerebrospinal fluid that communicates with the subarachnoid space, is one such complication. In order to evaluate and better understand the incidence, presentation, treatment, and outcome of PMC following cervical spine surgery, we conducted a multicenter study to pool our collective experience.This study was a retrospective, multicenter cohort study of patients who underwent cervical spine surgery at any level(s) from C2 to C7, inclusive; were over 18 years of age; and experienced a postoperative PMC.Thirteen patients (0.08%) developed a postoperative PMC, 6 (46.2%) of whom were female. They had an average age of 48.2 years and stayed in hospital a mean of 11.2 days. Three patients were current smokers, 3 previous smokers, 5 had never smoked, and 2 had unknown smoking status. The majority, 10 (76.9%), were associated with posterior surgery, whereas 3 (23.1%) occurred after an anterior procedure. Myelopathy was the most common indication for operations that were complicated by PMC (46%). Seven patients (53%) required a surgical procedure to address the PMC, whereas the remaining 6 were treated conservatively. All PMCs ultimately resolved or were successfully treated with no residual effects.PMC is a rare complication of cervical surgery with an incidence of less than 0.1%. They prolong hospital stay. PMCs occurred more frequently in association with posterior approaches. Approximately half of PMCs required surgery and all ultimately resolved without residual neurologic or other long-term effects.
