Retrospective cohort study at a single institution. Patients undergoing specific, elective spinal procedures between 2012 and 2018. ⋯ Patients receiving the lowest dosage of opioid prescriptions with sufficient nonopiate analgesics did not report worse pain relief at POD 30 compared to those receiving higher opioid prescriptions. In light of the opioid epidemic, this study supports initial dosing recommendations by the American Society for Addiction Medicine.Level of Evidence: 3.

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.
-
A retrospective analysis of prospectively collected data. ⋯ Constructing a prognostic ML model for surgical outcomes in patients with OPLL is feasible, suggesting the potential application of ML for predictive models of spinal surgery.Level of Evidence: 4.
-
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.

Multicenter Study
Characteristics of Tc-MEP Waveforms in Spine Surgery for Patients with Severe Obesity.
Prospective multicenter study. ⋯ Tc-MEPs can be used in spine surgery for severely obese cases to predict postoperative motor deficits, but the rate of undetectable waveforms is significantly higher in such cases. Use of a multichannel waveform approach or multiple modalities may facilitate safe completion of surgery. Waveforms should be carefully evaluated and an appropriate rescue procedure is required if the alarm criterion occurs.Level of Evidence: 3.
