Retrospective observational study. ⋯ 3.
-
Biomechanical Study. ⋯ This biomechanical investigation demonstrates that constructs that cross the cervicothoracic junction experience less overall spinal motion in flexion-extension compared to those that terminate at C7. However, contrary to prior studies there is no difference in cranial and caudal adjacent segment motion. Surgeons should make clinical decisions regarding the caudal extent of fusion in multi-level posterior cervical fusions without major concerns about adjacent segment motion.
-
A prospective non-randomized controlled study. ⋯ Therapeutic Level III.
-
Prospective trial comparing the investigation group to propensity matched historic control group. ⋯ PEEK-on-ceramic TDR produced significantly improved outcomes maintained throughout 5-year follow-up, were similar or superior to ACDF, supporting TDR in appropriately selected patients.
-
Retrospective cohort study. ⋯ Patients from socioeconomically disadvantaged communities experience longer hospitalizations and are more likely to be discharged to a rehabilitation or skilled nursing facility following PCDF. Social and economic barriers should be addressed as part of presurgical counseling and planning in elective spine surgery to mitigate these disparities and improve the quality and value of health care delivery, regardless of socioeconomic status.
