Multicenter Study
Translation, cross-cultural adaptation, and validation of a Chinese version of the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire.
Translation and psychometric testing of a questionnaire. ⋯ The results indicated that the Chinese JOACMEQ successfully retained the psychometric properties of the original JOACMEQ and support the usefulness of the Chinese JOACMEQ as an appropriate supplementary diagnostic and outcome measure for Chinese patients suspected of cervical spondylotic myelopathy.

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.

A case report. ⋯ NTS can be caused by even VP in patients with a pathological fracture. NTS needs to be considered in cases where it is difficult to inject polymethyl methacrylate.

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.

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.
