Randomized Controlled Trial Multicenter Study
Cost-effectiveness of balloon kyphoplasty versus standard medical treatment in patients with osteoporotic vertebral compression fracture: a Swedish multicenter randomized controlled trial with 2-year follow-up.
A multicenter, randomized, controlled, cost-effectiveness analysis. ⋯ In this randomized controlled trial, it was not possible to demonstrate that BKP was cost-effective compared with standard medical treatment in patients treated for an acute/subacute vertebral fracture due to osteoporosis. However, sensitivity analysis indicated a certain degree of uncertainty, which needs to be considered.

Randomized Controlled Trial Multicenter Study
Lumbar disc herniation in the Spine Patient Outcomes Research Trial: does educational attainment impact outcome?
Randomized trial with concurrent observational cohort. A total of 1171 patients were divided into subgroups by educational attainment: high school or less, some college, and college degree or above. ⋯ Patients with higher educational attainment demonstrated significantly greater improvement with nonoperative treatment while educational attainment was not associated with surgical outcomes.

Multicenter Study
Predicting health-utility scores from the Cervical Spine Outcomes Questionnaire in a multicenter nationwide study of anterior cervical spine surgery.
Cross-sectional analysis of the Cervical Spine Research Society Outcomes Study, a longitudinal multicenter cohort study. ⋯ Our findings show that the CSOQ's domain scores can be used to estimate health-utility scores among those undergoing elective anterior cervical decompression and fusion for cervical degenerative disc disease. The ability to assess health utility, coupled with the psychometric properties of the CSOQ, should increase the clinical utility of this patient-reported outcomes instrument.

Randomized Controlled Trial Multicenter Study
Lumbar disc arthroplasty with Maverick disc versus stand-alone interbody fusion: a prospective, randomized, controlled, multicenter investigational device exemption trial.
Randomized, controlled, multicenter, investigational device exemption trial. ⋯ The investigational group consistently demonstrated statistical superiority versus fusion on key clinical outcomes including improved physical function, reduced pain, and earlier return to work.
