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.

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.

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.
