Multicenter Study Comparative Study
Comparison of the lowest instrumented, stable, and lower end vertebrae in "single overhang" thoracic adolescent idiopathic scoliosis: anterior versus posterior spinal fusion.
A retrospective multicenter study. ⋯ These data confirm that anterior spinal fusion techniques result in a mean shorter fusion of 1.5 vertebral segments/patient when compared to posterior spinal fusion techniques with respect to the position of the lowest instrumented and stable vertebrae for "single overhang" thoracic (Lenke 1A/B) curves. However, because this is a retrospective multicenter study over 10 years, it represents various posterior spinal fusion techniques that do not include all pedicle screw constructs.

Randomized Controlled Trial Multicenter Study
Evaluation of surgical volume and the early experience with lumbar total disc replacement as part of the investigational device exemption study of the Charité Artificial Disc.
A prospective, randomized, multicenter, Food and Drug Administration regulated Investigational Device Exemption (IDE) clinical trial. ⋯ Surgeons and institutions with a high volume of lumbar total disc replacement cases have a reduction in key perioperative and postoperative parameters that provide a clinical and/or economic benefit. Surgeons may expect longer hospital stays, higher blood loss, and a higher rate of certain complications in their early experience with total disc replacement procedures, but there was no effect on clinical outcomes.

Multicenter Study Clinical Trial
Balloon kyphoplasty for symptomatic vertebral body compression fractures results in rapid, significant, and sustained improvements in back pain, function, and quality of life for elderly patients.
Prospective, single-arm interventional cohort. ⋯ Elderly patients with symptomatic VCFs had rapid, significant, and sustained improvements in back pain, back function, and quality of life following balloon kyphoplasty.

Randomized Controlled Trial Multicenter Study Comparative Study
Randomized controlled trial of specific spinal stabilization exercises and conventional physiotherapy for recurrent low back pain.
Pragmatic, multicentered randomized controlled trial, with 12-month follow-up. ⋯ Patients with LBP had improvement with both treatment packages to a similar degree. There was no additional benefit of adding specific spinal stabilization exercises to a conventional physiotherapy package for patients with recurrent LBP.
