A cross-sectional study based on an online questionnaire. ⋯ Level 4.

Retrospective case series. ⋯ Bundled payment models utilize wage index and diagnosis-related groups to determine reimbursement of ACDF. However, machine learning algorithms identified additional variables, such as hospital volume, readmission, and patient age, that are also important for determining the cost of care. Machine learning can improve cost-effectiveness and reduce the financial burden placed upon physicians and hospitals by implementing patient-specific reimbursement.

Observational Study
Anatomical Characteristics and Variations of Thoracic Segmental Arteries with 3-dimensional CT Analysis.
Observational study using retrospective contrast-enhanced computed tomography (CT) analysis. ⋯ The distribution of the segmental arteries was asymmetrical and varied depending on the vertebral level. In the upper to middle thoracic, segmental arteries ran at every position of the vertebral body due to their longitudinal nature and the presence of multiple segmental arteries within a single vertebra, especially in T5-7. The results of this study provide critical information for thoracic spine surgery.
