Randomized Controlled Trial Comparative Study
Cost-effectiveness and cost-benefit analyses of a multidisciplinary intervention compared with a brief intervention to facilitate return to work in sick-listed patients with low back pain.
Randomized clinical trial of 2 interventions in 351 employees sick listed due to low back pain (LBP) and a subsequent validation study (n = 120) to validate results from subgroup analyses in the original study. ⋯ 2.

Comparative Study
What is the incidence of dysphagia after posterior cervical surgery?

Surgeons should counsel their patients about possibility for dysphagia prior to all cervical spine surgery.

Multicenter Study
Radiographical spinopelvic parameters and disability in the setting of adult spinal deformity: a prospective multicenter analysis.
Prospective multicenter study evaluating operative (OP) versus nonoperative (NONOP) treatment for adult spinal deformity (ASD). ⋯ ASD is a disabling condition. Prospective analysis of consecutively enrolled patients with ASD demonstrated that PT and PI-LL combined with SVA can predict patient disability and provide a guide for patient assessment for appropriate therapeutic decision making. Threshold values for severe disability (ODI > 40) included: PT 22° or more, SVA 47 mm or more, and PI - LL 11° or more.
