Randomized Controlled Trial Multicenter Study Observational Study
Relationship between lumbar spinal stenosis and lifestyle-related disorders: a cross-sectional multicenter observational study.
A cross-sectional multicenter observational study. ⋯ After adjusting for age and sex, this study revealed a close association between diabetes and hypertension in 50- to 69-year-old patients with LSS. Physicians should consider the possibility of concomitant hypertension or diabetes mellitus when examining 50- to 69-year-old patients with LSS.

Randomized Controlled Trial Comparative Study
Five-year reoperation rates, cervical total disc replacement versus fusion, results of a prospective randomized clinical trial.
Prospective randomized clinical trial. ⋯ Five-year follow-up of a prospective randomized clinical trial revealed 5-fold difference in reoperation rates when comparing patients who underwent ACDF (14.5%) with patients who underwent TDR (2.9%). These findings suggest the durability of TDR and its potential to slow the rate of adjacent-level disease.

A retrospective, multicenter study. ⋯ Since the residual apical translation of the main thoracic curve and the lowest instrumented vertebra more cranial to the last touching vertebra were significantly associated with adding-on, surgeons may need to obtain the maximum reduction of the apical translation of the main thoracic curve and to extend the LIV at least to the LTV to avoid postoperative adding-on.

Case report. ⋯ This case report presents the association between suboccipital muscles and AARF, suggesting that the soft tissue release of suboccipital muscle group may facilitate recovery from AARF. More studies are needed to verify the inferences of this case report.

Prospective cohort study. ⋯ Postoperative STS is a self-limiting process. The magnitude of STS during the postoperative period does not seem to influence the development of chronic dysphagia.
