Observational Study
Factors Affecting Pedicle Screw Insertional Torque in Spine Deformity Surgery.
Retrospective observational study of consecutive patients. ⋯ We propose the concept of an optimal S/P ratio for obtaining rigid pedicle screw fixation during spinal corrective surgery, which is different for patients with ASD and patients with AIS. The S/P ratio is useful for deciding the appropriate diameter screw for each case in preoperative planning.Level of Evidence: 4.

Retrospective cohort study. ⋯ The incidence of surgical site infection in NMS patients decreased significantly (16.1% vs. 4.4%) after the implementation of the strategies mentioned in the 2013 Best Practice Guideline. Further studies are required to continue to decrease the incidence in this high-risk population.Level of Evidence: 3.
