Retrospective cohort study. ⋯ The five-factor National Surgical Quality Improvement Program modified frailty index is an effective predictor of postoperative events following spine surgery. Severity of frailty score by the mFI-5 was associated with increased morbidity and mortality. The mFI-5 within a surgical spine population can reliably predict post-op complications. This tool is less cumbersome than mFI-11 and relies on readily accessible variables at the time of surgical decision-making.Level of Evidence: 3.

Retrospective study using prospectively collected data. ⋯ Alternative antimicrobial prophylaxis agents increased the risk of reoperation for SSI after spine surgery compared with cefazolin. Our study supports the current practice of using first-generation cephalosporins as first-line antimicrobial prophylaxis agents in spine surgery as recommended in multiple guidelines.Level of Evidence: 3.

A retrospective study. ⋯ In the present study, many factors were related to AS during 1-year after surgery. What's more, patients with smoking and preoperative Mcs were associated with AS at any follow-up. We hope this article can provide a reference for spinal surgeons to predict which patients were susceptible to suffer from AS after anterior surgery in treatment of multilevel cervical disorder with kyphosis.Level of Evidence: 3.

Cost-effectiveness analysis. ⋯ The combined protocol was less costly and more effective than the traditional protocol. Results were robust with thresholds occurring outside published ranges. Bariatric surgery is a viable, cost-effective preoperative strategy in obese patients considering elective PLDF for DS.Level of Evidence: 3.

An experimental investigation of a robot-assisted ultrasonic osteotome applied to vertebral cancellous bone. ⋯ The optimal parameters for applying a robot-assisted ultrasonic osteotome to vertebral cancellous bone are L-T mode, maximum output power of 120 W, and maximum feed rate of 2.4 mm/s.Level of Evidence: 4.
