Prospective cohort study. ⋯ The PROMIS-29 scale scores assessing pain intensity, physical function, and anxiety evidenced the most responsivity in the study sample. The results, when considered in light of the findings from other investigators, support 5.0 points as a reasonable MCID for most of the PROMIS-29 scales. Further studies are needed to determine the generalizability of the findings.Level of Evidence: 2.

Retrospective observational study. ⋯ Patients with pedicle screw stimulation thresholds less than or equal to 8 mA are 4.34 times more likely to have neurological clinical manifestations. Smoking and LE deficits were shown to be significantly correlated with pedicle screw stimulation thresholds less than or equal to 8 mA. Low stimulation thresholds result in a high specificity of 90%. Pedicle screw stimulation less than or equal to 8 mA can serve as an accurate rule in test for postoperative neurological deficit, warranting reevaluation of screw placement and/or replacement intraoperatively.Level of Evidence: 3.

A 2-year follow-up review of 62 patients with severe rigid scoliosis (>120°). ⋯ For severe rigid scoliosis with a Cobb angle greater than 120°, a combination of short-term presurgical HPT and posterior surgery is an effective and safe solution. After 4 to 6 weeks of presurgical HPT the Cobb angle can be decreased by approximately 50%, providing a favorable condition for spine corrective surgery.Level of Evidence: 3.

Retrospective database analysis. ⋯ This study demonstrates a clear national paradigm shift in the management of geriatric odontoid fractures, wherein operative management nearly doubled from 46% in 2003 to 86% in 2017.Level of Evidence: 3.
