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 review of the literature. ⋯ It may be possible for IMCLs to serve as a 'proxy' prognostic marker of lumbar MF-AMI in CLBP patients. Further, if this assertion were correct, then reductions in IMCLs could potentially quantify recovery and the efficacy of rehabilitation management strategies directed at lumbar MF activation.Level of Evidence: 5.

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.

A case control study. ⋯ Cervical malalignment patients had more tensional posterior cervical muscle and poor muscle functions. CG-SVA showed advantages in evaluating cervical malalignment.Level of Evidence: 3.
