The occurrence of surgical site infection (SSI) after lumbar spinal fusion is a serious complication. Therefore, an increasing number of clinicians are applying vancomycin powder topically in the surgical field to reduce the incidence of SSI. However, there is concern that topical vancomycin powder application may affect intervertebral fusion. The purpose of this study was to analyse the effect of clinically relevant topical vancomycin doses on the rate of intervertebral fusion after lumbar fusion and to further investigate the effect of vancomycin powder on the prevention of SSI. ⋯ Topical application of 0.5 g, 1.0 g, or 1.5 g vancomycin powder did not affect the rates of intervertebral fusion after lumbar fusion. In addition, topical application of vancomycin powder significantly reduced the rates of SSI.

Case Reports
Endoscopic Transsphenoidal Resection of Cystic Third Ventricular Craniopharyngioma with Cysto-Cisternal Fenestration.
Cystic craniopharyngiomas of the third ventricle can be challenging to treat because complete resection of the cyst wall can be associated with hypothalamic dysfunction and minimal rostral displacement of the optic chiasm leads to a small endonasal operative corridor. Various methods to overcome the frequent recurrences have been described, such as intracystic bleomycin or catheter placement, with mixed results.1-12 In Video 1, we describe a simple cystocisternal fenestration technique with preservation of the rostral cyst wall via an endoscopic endonasal approach where the solid portion of the tumor is resected, and the inferior wall of the cyst is opened into the prepontine cistern and the superior wall of the cyst and adjacent third ventricle are preserved. This allows for ventricular pressure to collapse the cyst cavity in the postoperative period. In select patients where safe complete resection of a cystic craniopharyngioma is prohibitive, this may provide a durable treatment and can be performed through a small endonasal corridor below a nondisplaced optic chiasm.

Giant falcine meningiomas are surgically complex as they are deep in location, concealed by normal brain parenchyma, in close proximity to various neurovascular structures, and frequently involve the falx bilaterally. Although classically accessed using a bifrontal craniotomy and interhemispheric approach, little data exist on alternative operative corridors for these challenging tumors. We evaluated perioperative and long-term outcomes in patients undergoing transcortical resection of giant bilateral falcine meningiomas. ⋯ The transcortical approach is a safe alternative corridor for accessing giant, falcine meningiomas, and postoperative seizures were not found to correlate with increasing corticectomy depth. Further prospective studies are necessary to determine the best approach to these surgically complex lesions.

This study aimed to explore the clinical efficacy of metagenomic next-generation sequencing (mNGS) in diagnosing and treating suspected spinal infectious diseases. ⋯ mNGS demonstrated significantly higher detection rates for bacterial, fungal, viral, and mixed infections in cases of suspected spinal infectious diseases. The clinical implementation of mNGS could further enhance the efficiency of diagnosing and treating suspected spinal infectious diseases.
