Randomized Controlled Trial
The Influence of Simulated Low Speed Vehicle Impacts and Posture on Passive Intervertebral Mechanics.
An in vitro biomechanics investigation exposing porcine functional spinal units (FSUs) to sudden impact loading although in a flexed, neutral, or extended posture. ⋯ Functional spinal units exposed to the highest severity impact (11 g) had significant neutral zone changes, with increases in joint laxity in flexion-extension and anterior-posterior shear and decreased stiffness, suggesting that soft tissue injury may have occurred. Despite observed main effects of impact severity, no influence of posture was observed.Level of Evidence: N/A.

A cross-sectional study. ⋯ The prevalence of NeP was reported to be 46.0% in healthy middle-aged and elderly population suffering from NSP, where it was associated with poor HRQOL. Therefore, strategies aimed at alleviating NeP may contribute significantly to the improvement of QOL in middle-aged and elderly people with NSP.Level of Evidence: 2.

Delphi expert panel consensus. ⋯ Although telemedicine was initially introduced out of necessity, this technology most likely will remain due to evidence of high patient satisfaction and significant cost savings. This study was able to provide a framework for appropriate telemedicine utilization in spine surgery from a panel of experts. However, several questions remain for future research, such as whether or not an in-person consultation is necessary prior to surgery and which physical exam maneuvers are appropriate for telemedicine.Level of Evidence: 4.

Genetic cross-over study of intervertebral disc degeneration (IDD) and its associated risk factors. ⋯ Genetic association between IDD and risk factors in the general population was revealed by association network. Important gene-related molecular pathways and chemical drugs closely related to IDD have been found. Further study can provide guidance for the treatment and prognosis of IDD.Level of Evidence: N/A.

Finite element analysis (FEA) and in vivo ovine spinal interbody fusion study. ⋯ Validating FEA estimates, cages with smaller diameter struts exhibited more rapid fusion consolidation and more aggressive osseointegration compared with cages with larger diameters struts.Level of Evidence: 4.
