Retrospective observational cohort study. ⋯ We propose a classification for the severity of ATCSCI based on DTI and DTT that may explain why some patients with ASIA A recover, whereas others do not.Level of Evidence: 4.

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 Comparative Study
Comparison of 2-level cervical disc replacement vs. 2-level anterior cervical discectomy and fusion in the outpatient setting.
Retrospective cohort study. ⋯ To our knowledge, this is the largest multicenter study examining the safety of two-level outpatient CDR procedures. Outpatient two-level CDR was associated with similarly safe outcomes when compared to inpatient two-level CDR and outpatient two-level ACDF. This suggests that two-level CDR can be performed safely in the outpatient setting.Level of Evidence: 3.
