Randomized Controlled Trial
Equal Ratio Ventilation Reduces Blood Loss During Posterior Lumbar Interbody Fusion Surgery.
A prospective randomized double-blinded study. ⋯ Compared to conventional ratio ventilation, ERV provided lower PIP and reduced intraoperative surgical blood loss in patients undergoing PLIF surgery.Level of Evidence: 2.

Multicenter Study
A Risk Benefit Analysis of Increasing Surgical Invasiveness Relative to Frailty Status in Adult Spinal Deformity Surgery.
Retrospective review of a prospectively enrolled multicenter Adult Spinal Deformity (ASD) database. ⋯ Increasing invasiveness is associated with increased odds of major complications and reoperations. Risk-benefit cutoffs for successful outcomes were 79.3 for NF, 111 for F, and 53.3 for SF patients. Above these, increasing invasiveness has increasing risk of major complications or reoperations and not meeting MCID at 3Y.Level of Evidence: 3.

Retrospective cohort study. ⋯ Decompression and DS surgery for LSS with or without spondylolisthesis showed favorable long-term surgical outcomes with an acceptable rate of complications and ASD. However, an improved physiological DS system should be developed.Level of Evidence: 4.
-
Pre-post study. ⋯ Using a multiteam and multidisciplinary approach to recruitment may increase the likelihood that individuals with an acute SCI and their caregivers enroll in research.Level of Evidence: 3.

Observational Study
Infra-adjacent Segment Disease After Lumbar Fusion: An Analysis of Pelvic Parameters.
Cross-sectional observational cohort study. ⋯ Incidence of the SIJ dysfunction after lumbosacral fusion surgery was 3.9% and these patients had a significantly lower PT and L5 incidence compared to the control group. Significantly low PT may be derived from weak hamstring muscles, predisposing a patient to SIJ dysfunction. Therefore, hamstring muscle strengthening exercise for patients with decreased PT after lumbosacral fusion may decrease the incidence of SIJ dysfunction.Level of Evidence: 3.
