Retrospective case-control study. ⋯ Many medical comorbidities have less impact in obese patients than nonobese patients in predicting adverse outcomes despite increased rates of adverse outcomes in obese patients. These findings reflect the impact of obesity as an independent risk factor and have important implications for preoperative optimization.Level of Evidence: 3.

Comparative Study
Comparison of Morphometric Measurements of Raditional Posterior Cervical Screw and Paravertebral Foramen Screw in Chinese Population.
A morphometric measurement study. ⋯ Although the length of PVFS is limited, it still can be used as an effective substitute for LMS and PS. The PVFS does not have the risk of directly injuring the vertebral artery, its safety angle of insertion is larger than that in PS, and it has higher surgical safety.Level of Evidence: 3.

Multicenter Study Observational Study
Impact of New Motor Deficit on HRQOL after Adult Spinal Deformity Surgery: Subanalysis from Scoli Risk 1 Prospective Study.
International, multicenter, prospective, longitudinal observational cohort. ⋯ In the subgroup of deformity patients who developed a new motor deficit, total HRQOLs and HRQOL changes were negatively impacted. Patients with more than 2 points of LEMS worsening had the worst changes, but still showed overall HRQOL improvement at 6 months and 2 years compared with pre-op baseline.Level of Evidence: 3.
