Retrospective cohort study. ⋯ Our analysis of ABOS Part II candidates demonstrates that reported complication rates may be increasing while mortality is decreasing. The etiologies behind these findings are likely multifactorial. Encouragingly, we believe that observed reductions in mortality suggest overall improvements in patient safety following spine surgery. At a minimum, our data provide benchmarks through which spine surgeons, hospitals, and residency or fellowship programs can evaluate performance.Level of Evidence: 4.

This is an observational study on the measurement properties of the Oswestry Disability Index (ODI) version 1.0. ⋯ Our study lends value to a burgeoning repository of evidence that suggests the ODI is a useful tool for capturing outcomes in clinical practice. We recommend its continued use in clinical practice.Level of Evidence: 4.

The study is designed as a retrospective cohort study. ⋯ Glycopyrrolate use, benign prostate hyperplasia, and postoperative urinary tract infection were independent risk factors for postoperative urinary retention. The use of glycopyrrolate is a potentially modifiable risk factor for postoperative urinary retention.Level of Evidence: 3.

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.

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.
