Clinical Trial Summary

A multicenter, prospective, non-randomized, historically controlled study. To demonstrate the Synergy Disc is at least as safe and effective as conventional anterior cervical discectomy and fusion (ACDF) to treat cervical degenerative disc disease (DDD) in subjects who are symptomatic at two levels from C3 to C7 are and are unresponsive to conservative management. Patients will be evaluated preoperatively, at the time of surgery, and at 6 weeks, and 3, 6, 12, and 24 months after surgery. Follow-up will continue annually until the last patient reaches 24-month follow-up. The primary analysis will occur at 24 months.


Clinical Trial Description

The proposed investigation is a prospective, non-randomized, multi-center, historically controlled comparison of the Synergy Disc to the control of conventional anterior cervical discectomy and fusion (ACDF) surgery in patients with cervical DDD. A total of 200 patients will be enrolled to the investigational group .The objective of this clinical study is to evaluate the safety and effectiveness of the two-level Synergy Disc compared to conventional two-level ACDF in skeletally mature patients for reconstruction of two contiguous discs from C3 to C7 following discectomy at two contiguous levels for intractable radiculopathy (arm pain and/or a neurological deficit) with neck pain or myelopathy due to abnormalities localized to the levels of the two contiguous disc spaces that are unresponsive to conservative management. ;
