Retrospective cohort study of 183 patients who underwent elective anterior cervical discectomy and fusion (ACDF) at a single institution during a 2-year period. ⋯ 3.

Comparative Study
Surgery for spinal stenosis: long-term reoperation rates, health care cost, and impact of instrumentation.
Retrospective cohort analysis. ⋯ For patients with spinal stenosis, if fusion is warranted, use of arthrodesis without instrumentation is associated with decreased costs with similar long-term complication and reoperation rates.
-
Retrospective analysis of kinematic magnetic resonance images. ⋯ Cervical spine studies that aim to investigate kyphotic deformities should make efforts to discern the different subtypes of kyphotic deformities to more accurately characterize and study the effects that the sagittal alignment has on the kinematics of the spine and the degree of spinal cord compression.
-
Retrospective study. ⋯ It seems that upper cervical levels are more likely to degenerate and to have more advanced degrees of degeneration than the lower cervical levels. As expected, age correlates with worsening degeneration. The proposed computed tomographic grading system for cervical facet arthrosis seemed to be reliable.

Retrospective review of prospective database. ⋯ Extension of long fusions to the sacrum resulted in significant and sustained improvements in Oswestry Disability Index and Scoliosis Research Society scores and alignment during 5 years PO compared with baseline. Major surgical complications occurred in 30% and reoperations were performed in 20%, but outcome scores after treatment were similar to those without complications or reoperations.
