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.
-
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.

Multicenter Study
Does Achieving Global Spinal Alignment Lead to Higher Patient Satisfaction and Lower Disability in Adult Spinal Deformity?
Multicenter retrospective review of prospective database. ⋯ The ability to restore global alignment depends on the severity of the preoperative deformity as well as the correction of the main aspect of the deformity. Achieving global coronal and sagittal alignment is an independent predictor of both satisfaction and disability at 2 years post-op. Patients who continue to be disabled are also not satisfied.Level of Evidence: 3.

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. ⋯ This study revealed that lumbar degenerative disease patients, who have greater preoperative kyphotic lumbar alignment in the standing versus supine position, tend to have postoperative residual symptoms after TLIF. A preoperative comparison of lateral radiographs between the standing and supine positions is useful to predict patients' postoperative residual symptoms.Level of Evidence: 3.
