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.
-
Retrospective cohort studying using a national, administrative database. ⋯ Patients with a diagnosis of obesity at time of LDD surgery are at a higher risk for postoperative complications, reoperation, and readmission.Level of Evidence: 4.

Observational Study
Subaxial Spine Fractures: A Comparison of Patient-reported Outcomes and Complications Between Anterior and Posterior Surgery.
Observational study on prospectively collected data. ⋯ Anterior surgery and posterior surgery were associated with similar neck disability and general quality of life at follow-up, whereas anterior surgery was associated with higher patient satisfaction and lower infection rates.Level of Evidence: 3.

In vitro and in vivo laboratory studies. ⋯ CC suppressed S. aureus and P. acnes proliferation compared with Ti in vitro and in an in vivo infection model.Level of Evidence: N/A.
