Quasi-experimental intervention study. ⋯ After implementation of the care bundle, the incidence of SSI in spine fusion surgery decreased significantly. Multivariate analysis showed that the care bundle was an independent protective factor. The implementation of these measures should be reinforced on the routine medical practice to reduce the SSI incidence.Level of Evidence: 3.

Multicenter Study
Passive Recharge Burst Spinal Cord Stimulation provides sustainable improvements in pain and psychosocial function: 2-year results from the TRIUMPH study.
Prospective, international, multicenter, single-arm, post-market study. ⋯ Early positive results with B-SCS were maintained long term. Evidence across multiple assessment tools show that B-SCS can alleviate pain intensity, psychological distress, and improve physical function and health-related quality of life.Level of Evidence: 3.

The 2001 Functional Rating Index (FRI) was not developed under today's standard psychometric analysis. The original data of 108 cases were re-analyzed using Rasch item response theory. In 2015, 2 alternative forms were administered to an additional 140 patients for establishing and perhaps improving its psychometric characteristics. ⋯ The original FRI and alternative forms all fail failed crucial psychometric tests and fail to accurately measure more than one latent construct. It is thus unfit as a pain, function, and disability assessment. Only reducing the number of Likert choices improved the test. Other back pain assessments should be used instead, and all surveys would benefit from periodic item responses to adjust to shifts in grammar and meaning.Level of Evidence: 3.

Multicenter Study
Scheuermann Kyphosis Patients have a Similar Revision and Infection Rate to Adolescent Idiopathic Scoliosis Patients.
Multicenter retrospective review. ⋯ Contrary to previously published literature, our analyses indicate that in a matched population, postoperative complication rates (i.e., infection and revision rates) are not significantly different between SK and AIS patients.Level of Evidence: 4.

Observational Study
A Natural History of Patients Treated Operatively and Non-Operatively for Spinal Metastases Over 2 Years Following Treatment: Survival and Functional Outcomes.
Prospective observational study. ⋯ We found that patients treated operatively and nonoperatively for spinal metastases benefitted from treatment in terms of HRQL. Two-year mortality for the cohort as a whole was 70%. When prognosticating survival, the NESMS appears to be an effective utility, particularly among patients with scores of 0 or 1.Level of Evidence: 2.
