Viscosity of PMMA Bone Cement in Percutaneous Vertebroplasty for Osteoporotic Vertebral Compression Fractures: A Randomized Controlled Trial

Establishment whether usage of high viscosity PMMA bone cement in PVP for OVCFs leads to a reduction in leakage incidence compared to usage of conventional (low-medium) viscosity PMMA bone cement in PVP for OVCFs.Since evidence is scarce or…

A randomised multicenter study comparing anterior cervical discectomy with or without interbody fusion and arthroplasty in the treatment of cervical disc herniation.

To show whether Active C disc prosthesis is more effective than anterior discectomy with or without interbody fusion 1 year after surgery. Moreover, the incidence of adjacent disc degeneration will be evaluated 5 years after surgery.

A MULTI-CENTER, POST MARKETING SURVEILLANCE STUDYTO MONITOR THE SAFETY AND PERFORMANCEOF THE BARRICAID® ARD IN THE TREATMENT OF BACK ANDRADICULAR PAIN CAUSED BY PRIMARY LUMBAR DISCHERNIATION

Safety and performance will be based on a comparison of overall success rates of the Barricaid ARDand either a concurrent group (nonrandomized) of control patients treated by conventional surgicalmethods (e.g., noninstrumented discectomy) at select…

Interbody fusion devices in the treatment of cervicobrachial syndrome; a blinded randomised trial of cancellous structured ceramic (CSC) versus PEEK cages.

To compare functional recovery of the patient and the fusion status of ceramic cages versus PEEK cages on the short and long term.

Cost-effectiveness of minimal invasive spinal fusion compared to open fusion for patients with spinal stenosis with neurogenic claudication or radicular leg pain.

What is the cost-effectiveness of minimal invasive posterior lumbar interbody fusion in spinal stenosis patients, compared to the standard open fusion?

*A prospective randomized multicenter study to demonstrate the superiority of the Barricaid® to discectomy for primary lumbar disc herniation*: Extended Follow-Up of the Barricaid® Annular Closure Device (ACD) Randomized Control Trial (RCT) Postmarket Cohort for Lumbar Disc Herniation and Interaction with Other Risk Factors

The purpose of this post-approval protocol amendment is to extend the follow-up of subjects who were originally enrolled in theRCT, EUBARD-CP_001 protocol. This study extension will examine the long-term survivorship of the Barricaid® ACD when…
