A biomechanical comparison study using finite element method. ⋯ Under static and vibration loadings, the PBDSSbased topping-off device (Bioflex) provided a better protection for transition segment, and likelihood of degeneration of supraadjacent segment might be relatively lower when using the ISPbased topping-off device (DIAM).Level of Evidence: 5.

This study is a meta-analysis of prospective and retrospective studies identified in PubMed, Web of Science, and Embase with outcomes of patients who received intraoperative somatosensory-evoked potential (SSEP) monitoring during lumbar spine surgery. ⋯ SSEP changes during lumbar spine surgery are highly specific but moderately sensitive for new postoperative neurological deficits. Patients who had postoperative neurological deficit were 22 times more likely to have exhibited intraoperative SSEP changes.Level of Evidence: 2.
-
Retrospective chart review. ⋯ Prior thyroidectomy and number of spinal levels addressed during ACDF were identified as risk factors for postoperative otolaryngologic complications including dysphagia. Revision ACDF was not associated with increased odds of postoperative otolaryngologic symptoms or dysphagia.Level of Evidence: 4.

Cross-sectional survey. ⋯ Overall, the Arbeitsgemeinschaft für Osteosynthesefragen spine sacral classification system appears to be universally applicable among surgeons of various subspecialties and levels of experience with acceptable reliability, reproducibility, and accuracy.Level of Evidence: 4.
