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.

Observational cross-sectional study. ⋯ Text neck was not associated with prevalence of NP, NP frequency, or maximum NP intensity in adults.Level of Evidence: 4.
-
Case-report and literature review. ⋯ Instrumentation removal and metallosis debridement seems to be useful for symptomatic patients, but remains controversial on fixed asymptomatic patients. If solid fusion has not been achieved, extension, and reinforcement of the failed fixation could be required.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.
