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 Comparative Study
A randomized trial comparing acupuncture and simulated acupuncture for subacute and chronic whiplash.
A randomized controlled trial with 3 and 6 months follow-up. ⋯ Real electroacupuncture was associated with a significant reduction in pain intensity over at least 6 months. This reduction was probably not clinically significant. There was no improvement in disability or quality of life.

Randomized Controlled Trial
Multidisciplinary intensive functional restoration versus outpatient active physiotherapy in chronic low back pain: a randomized controlled trial.
Randomized parallel group comparative trial with a 1-year follow-up period. ⋯ Both programs are efficient in reducing disability and sick-leave days. The FRP is significantly more effective in reducing sick-leave days. Further analysis is required to determine if this overweighs the difference in costs of both programs.

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.

Randomized Controlled Trial Comparative Study
Segmental contribution toward total cervical range of motion: a comparison of cervical disc arthroplasty and fusion.
Prospective radiographic evaluation of patients that underwent cervical total disc replacement (TDR-C) or anterior cervical discectomy and fusion (ACDF) for one-level cervical disc disease. ⋯ Compensation for the loss of motion at the operative level in ACDF is seen throughout the unfused cervical spine. Cervical disc arthroplasty, however, increases total cervical ROM compared with ACDF and maintains a physiologic distribution of ROM throughout the cervical spine at 2 years, potentially lowering the risk for adjacent segment breakdown.
