Randomized Controlled Trial Multicenter Study
Predictive Factors Affecting Surgical Outcomes in Patients With Degenerative Lumbar Spondylolisthesis.
Post-hoc analysis of 5-year follow-up data from a prospective randomized multicenter trial. ⋯ While the degree of vertebral slippage and the presence of angulation were not associated with poor recovery after surgery for lumbar degenerative spondylolisthesis, postoperative outcomes were associated with the intervertebral angle and the presence of translation. Careful preoperative measurement of these factors may help to predict poor postoperative outcomes.Level of Evidence: 3.

Multicenter Study Comparative Study
A Comparison of Three Different Positioning Techniques on Surgical Corrections and Post-operative Alignment in Cervical Spinal Deformity (CD) Surgery.
Retrospective review of a prospective multicenter cervical deformity database. ⋯ Postoperative cervical sagittal correction or alignment was not affected by patient position. The majority of segmental correction occurred at C4-5-6 across all positioning methods, while bivector traction had the largest corrective ability at the cervicothoracic junction.Level of Evidence: 4.

Meta Analysis
Thoracolumbar Burst Fracture: McCormack Load-Sharing Classification - Systematic Review and Single Arm meta-Analysis.
A systematic review and single-arm meta-analysis of randomized clinical trials. ⋯ Load-sharing scores up to 6 are 100% reliable, only requiring posterior instrumentation for stabilization. For scores >6, the risk of implant breakage and loss of kyphosis correction in posterior fixation alone is low. Thus, other factors should be considered to define the best surgical approach to be adopted.Level of Evidence: 1.

Multicenter Study
Predictors of Superior Recovery Kinetics in Adult Cervical Deformity Correction: An Analysis Using a Novel Area Under the Curve Methodology.
Retrospective review of a prospective database. ⋯ Superior recovery kinetics following CD surgery was predicted with high accuracy using BL patient-reported (VAS EQ5D, swallow sleep, mJOA) and radiographic factors (PT, TK, T10-L2, T12-S1, L1-S1). Awareness of these factors can improve decision-making and reduce postoperative neck disability.Level of Evidence: 3.

Cultural adaptation and psychometric analysis. ⋯ This is the first study in Nigeria to culturally adapt PSEQ. The PSEQ-Y showed adequate psychometric properties similar to existing versions. Therefore, the tool can be used to assess pain self-efficacy in clinical and research settings and help to improve the health outcomes of patients chronic LBP.Level of Evidence: 3.
