Prospective longitudinal study. ⋯ The present study demonstrated dynamics of BTMs after lumbar spinal fusion in patients without osteoporosis. These normal population data contribute as a baseline to evaluate the effect of osteogenic agents on bone metabolism after spinal fusion.Level of Evidence: 2.
-
Retrospective cohort. ⋯ We identified several novel drivers of radiation exposure during interbody fusion procedures, including the relative importance of technique and the level at which the fusion is performed. More caudal levels of intervention and lateral based techniques had significantly greater radiation exposure.Level of Evidence: 4.

Observational Study
What is the Return on Investment of Spine Society Research Grants?
Retrospective, observational -study. ⋯ CSRS grants appear to have the highest ROI of all spine society grants when evaluating subsequent NIH and DOD funding. However, the overall conversion rate to NIH and DOD grants remains low.Level of Evidence: 3.
