Retrospective cohort study and systematic literature review. ⋯ The return-to-work rates for a universal no-fault compensation system are higher than those under WC cover, and are compatible with non-WC cases. This suggests that the features of WC may contribute to the inferior return-to-work rates.

Retrospective dose-simulation comparison. ⋯ Spinal CT scans done for preoperative planning can be performed at 25% of current radiation doses without a loss in surgical planning measurement accuracy or precision. These 25% dose-reduced scans would have average Computed Tomography Dose Index volume dose levels of roughly 1.0 to 2.5 mGy (depending on patient size) and size-specific dose estimates of roughly 2.5 mGy representing a substantial dose savings compared to current practice for many sites. Standardization of consistent landmarks may be useful to further improve inter-rater concordance.

Cross-sectional analysis. ⋯ LSDI scores are low among asymptomatic volunteers, although stiffness-related disability increases with increasing age. Patients with ASD report substantial stiffness-related disability even prior to surgical fusion. Stiffness-related disability correlates with pain- and function-related disability measures among patients with spinal deformity.

A retrospective cohort study with chart review. ⋯ A large cohort of ACDF patients with more than 2 years of follow-up had reoperations for nonunion rates significantly lower than reported in the literature for radiographical nonunions. We think our data add to the literature an important parameter (reoperations for nonunion rates) and provide useful information for patients, spine surgeons, and health care payers.
