Multicenter Study
Residual Paresthesia after Surgery for Degenerative Cervical Myelopathy: Incidence and Impact on Clinical Outcomes and Satisfaction.
Multicenter, prospective cohort study. ⋯ 3.

This is a retrospective study of a consecutive case series of dropped head syndrome (DHS). ⋯ In DHS, contrast-enhanced MRI showed intramuscular enhancement of the cervical extensor muscles, which was not present in non-DHS cases. The enhanced muscles included the splenius capitis muscle in all cases. These findings may be useful for developing a strategy for DHS treatment.

Retrospective cohort study. ⋯ The findings suggest that patients with hypercholesterolemia have an increased risk of developing pseudarthrosis following PLIF/TLIF while statin use is associated with a decreased risk. The data presented may underscore an overlooked opportunity for perioperative optimization in lumbar fusion patients, warranting further investigation in this area.

Multicenter Study
Cannabis Use is Associated with Higher Rates of Pseudarthrosis Following TLIF: A Multi-Institutional Matched-Cohort Study.
This was a retrospective cohort study. ⋯ After 1:1 exact matching to control for confounding variables, the findings of this study suggest that cannabis use is associated with higher rates of pseudarthrosis, as well as higher rates of all-cause surgical and all-cause medical complications. Further studies are needed to corroborate our findings.
