Clinical Trial Summary

The objective of this study is to investigate the clinical and radiological results of two-level cervical ProDisc-C vivo versus hybrid construct.


Clinical Trial Description

This is a prospective, randomized, multicenter trial at 7 years of follow-up comparing two level ProDisc-C vivo artificial cervical disc replacement and hybrid construct, i.e., combining ACDF (Anterior cervical discectomy fusion) and ProDisc-C vivo to treat degenerative disc disease (DDD). 542 DDD patients (age from 20 to 70) from several hospitals matching the inclusion criteria will be randomly assigned to two groups (271 patients in each group). One group will be treated with two level ProDisc-C vivo disc replacement. The other group will be treated with hybrid construct. Clinical outcomes and radiological analysis will be done at 1.5, 3, 6, 12, 24, 36, 60, and 84 months after the surgical treatments. ;
