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.

Case Reports
Traumatic expulsion of T4 vertebral body into the spinal canal treated by vertebrectomy and spine shortening.
A case report. ⋯ Total vertebrectomy and spinal shortening are safe and replicable procedures applicable in few patients with paraplegia. A surgical procedure after 3 weeks makes a complete reduction and a perfect sagittal alignment of the spine difficult to be obtained.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of 2 lumbar total disc replacements: results of a prospective, randomized, controlled, multicenter Food and Drug Administration trial with 24-month follow-up.
This was a prospective, randomized, controlled multicenter study with 24-month follow-up. ⋯ This prospective, randomized, controlled study comparing 2 TDRs, the first to the authors' knowledge, found the devices produced very similar clinical outcomes. Both groups improved significantly by 6 weeks postoperatively and remained improved throughout follow-up with a high patient satisfaction rate.

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 analysis of a population-based insurance claims data set. ⋯ Although previous studies have demonstrated superior efficacy for the treatment of FBSS, SCS remains underused. Despite no significant decreases in overall health care cost with SCS implantation, because it is associated with decreased complications and improved outcomes, this technology warrants closer consideration for the management of chronic pain in patients with FBSS.
