Cervical disk arthroplasty replacement (CDA) was developed to avoid specific disadvantages of cervical fusion. The purpose of this paper is to provide 10-year follow-up results of an ongoing prospective study after CDA. ⋯ Our 10-year results showed significant improvement in all clinical outcomes, with low rates of revision or failure. This experience in patients with long-term follow-up after CDA endorses durable, favorable outcomes in properly selected patients.

Optimizing the Definition of Proximal Junctional Kyphosis: A Sensitivity Analysis.
Diagnostic binary threshold analysis. ⋯ Out of all possible PJA magnitude and change combinations, without stratifying by upper thoracic versus lower thoracic fusions, a magnitude of ≤-28° and a change of ≤-22° provide the best test performance metrics for predicting PJF.

Multicenter Study
Long-Term Clinical, Radiographic, and Cost Analysis of Corrective Spine Surgery for Adult Symptomatic Lumbar Deformity With a Mean of 7.5 years Follow-Up.
Multicenter retrospective study. ⋯ Long-term surgical outcomes for ASLDs were favorable, with a relatively low rate of late-stage complications and reoperations, as well as reasonable direct costs. Despite the higher reoperation and complication rate, ASLD patients of more advanced age achieved similar improvement to those in the younger age groups.

Multicenter Study
A Propensity Score-matched Analysis of Clinical Outcomes between Single- and Multi-level Intervertebral Decompression for Cervical Radiculopathy.
Retrospective multicenter study with propensity score matching. ⋯ In patients with cervical radiculopathy, the surgical outcomes of the SLDG showed better improvement in clinical outcomes than those of the MLDG. Numbness remained on the distal (arms) rather than the central (neck and upper back) areas in patients receiving multilevel decompression.
