Multicenter StudyTwo-Year Evaluation of the X-STOP Interspinous Spacer in Different Primary Patient Populations With Neurogenic Intermittent Claudication due to Lumbar Spinal Stenosis.
Multicenter, prospective single-arm study in patients diagnosed with neurogenic intermittent claudication because of lumbar spinal stenosis. ⋯ Overall data are consistent with the randomized pivotal Investigational Device Exemption trial. On the basis of the COS cohort which was subject to several additional years of failed conservative treatment, overall success rates do not improve as greatly in patients with long-standing lumbar spinal stenosis symptoms.

Randomized Controlled Trial Multicenter StudyReduction of Leg Pain by Oxiplex Gel After Lumbar Discectomy in Patients With Predominant Leg Pain and Elevated Levels of Lower Back Pain: A Prospective, Randomized, Blinded, Multicenter Clinical Study.
A prospective, randomized, blinded, multicenter clinical study. ⋯ The data from this study confirm and extend results of 2 previous studies in Italy and the United States that reported statistically significantly greater reductions in leg pain in gel-treated patients with severe preoperative low back pain compared with patients who only underwent decompression surgery.

Randomized Controlled Trial Multicenter StudyA pilot evaluation of the role of bracing in stable thoracolumbar burst fractures without neurological deficit.
Prospective, 2-center, observer-blinded, randomized controlled trial. ⋯ Neurologically intact patients with stable thoracolumbar burst fractures treated with or without bracing had similar radiographic and clinical outcomes at 6 months follow-up. The no-brace group had shorter in-hospital lengths of stay. Conservative therapy involving early mobilization without brace immobilization may be warranted. Further studies with a larger series of patients and longer follow-up are required for conclusive findings.

Multicenter StudyPatterns of shoulder imbalance in adolescent idiopathic scoliosis: a retrospective observational study.
Retrospective cohort study. ⋯ Preoperative shoulder levels in AIS may be concordant with the T1 or discordant-each can have left or right shoulder elevation or balanced shoulders. Further, the shoulder might be MT dependent or PT dependent. Theoretically therefore, surgical balancing of the shoulder and upper instrumented vertebra placement should not depend only on the magnitude and stiffness of the PT curve.
