Analytical biomechanical study using a finite-element (FE) model. ⋯ Using FEM, we observed that the paraspinal muscle volume decreases pressure exerted on the lumbar vertebral column. Based on these results, we believe that exercising to increase paraspinal muscle volume would be helpful for spinal pain management and preventing lumbar spine degeneration.Level of Evidence: N/A.

A retrospective analysis (2015-2019) of data collected from patients who underwent posterior lumbar spinal surgery. ⋯ Multiple independent risk factors were identified for early symptomatic DVT after posterior lumbar spine surgery. Postoperative prophylactic anti-coagulation treatment might be warranted for patients with high D-dimer or low potassium levels before the procedure.Level of Evidence: 4.

Retrospective review of prospective case-control study. ⋯ This is the largest study comparing the surgical outcomes of MIS and PSF. MIS patients benefit from increased kyphosis, fewer transfusion, lower opioid consumption, and shorter hospital stay with similar Cobb correction. Increased postoperative kyphosis is likely from muscle sparing dissection in MIS.Level of Evidence: 3.

Retrospective Cohort. ⋯ In this national sample, NAV was associated with a lower rate of total complications but no change in rates of neurological complications or reoperations. In addition, NAV was associated with a large increase in total payments, despite a modest decrease in hospital stay. Considering the increasing popularity of NAV, this study provides important context regarding the utility of NAV for AIS.Level of Evidence: 3.
