This is an international multicenter retrospective review of 219 surgically treated consecutive adult spinal deformity (ASD) patients who had a minimum of five fused segments, completed a 2-year follow-up. ⋯ We refined the PRISM by adding preventive procedures to the risk indices. Further validation and adjustment in a large different patient cohorts may improve the predictive probability of PRISM2.Level of Evidence: 3.

Numerical in-silico human spine stability finite element analysis. ⋯ This investigation demonstrated torso tissues exhibiting different roles toward static spine stability. The TLF appeared able to dissipate and absorb excessive loads, the muscles acted as antagonistic to external perturbations, and the IAP played a role limiting movement. Furthermore, the different combinations explored suggested an optimized engagement and coordination between different tissues to achieve a specific task, while minimizing individual work.Level of Evidence: N/A.

Randomized Controlled Trial
Effectiveness and Safety of Inelastic vs. Elastic Lumbosacral Orthoses on Low Back Pain Prevention in Healthy Nurses: A Randomized Controlled Trial.
A randomized controlled trial. ⋯ Six-month wearing of LSO showed neither a significant difference in preventing LBP nor causing adverse effects to participants.Level of Evidence: 1.

Retrospective study of data collected prospectively. ⋯ The degree of improvement in symptoms 6 hours after SNRB can predict the degree of improvement in LLRP at 12 months after surgery. However, symptomatic improvement after SNRB does not predict postoperative functional outcome or quality of life.Level of Evidence: 4.
