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.

Biomechanical study using cadaveric cervical spines. ⋯ Increases in the range of extension and lateral bending at C0-C1, which had not been reported previously, were observed. Further, the range of rotation on the right and left sides increased, in conjunction with the increased ranges at C0-C1 and C1-C2.Level of Evidence: N/A.

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.
