Cross-sectional cohort study. ⋯ We have developed a model that differentiates patients with ankylosing spondylitis/axial SpA from those with mechanical spinal disease and can be used as a self-completed screening tool.

A retrospective single-center study. ⋯ The parameter INTmin correlated with the occurrence of postoperative ACS. A cutoff point of 4.0 mm is most appropriate for alerting spine surgeons to a high likelihood of postoperative ACS.

Cost-effectiveness of single-level anterior cervical discectomy and fusion five years after surgery.
Longitudinal cohort. OBJECTIVE.: The purpose of this study is to determine the cost per quality-adjusted life year (cost/QALY) gained for single-level instrumented anterior cervical discectomy and fusion (ACDF) over 5 years. ⋯ Increasing health care costs call for demonstration of cost-effectiveness in order to justify payment for interventions, including ACDFs. This study indicates that at 5-year follow-up, single-level instrumented ACDF is both effective and durable resulting in a favorable cost/QALY gained as compared to other widely accepted health care interventions.

Retrospective investigation of cross-sectional data. ⋯ Our investigation revealed a substantially high prevalence of vitamin D abnormality in the analyzed population. Although advanced age is a well-established risk factor for hypovitaminosis, young adults undergoing fusion should not be overlooked with regard to vitamin D screening; this age bracket is less likely to have been previously supplemented. In the absence of better-recognized determinants, spinal disability indices may also be useful in identifying those with deficiency.
