Study Summary

This trial will compare the Synergy Disc, a new device, to ACDF surgery, the current standard of care, to see if the new device is at least as safe and effective.

Who is the study for?
This trial is for adults aged 18-70 with cervical degenerative disc disease at one level from C3-C7, who haven't improved after six weeks of non-surgical treatment. Participants should have certain symptoms like arm pain or weakness and be able to follow the study's check-up schedule. People with previous major neck surgeries, multiple affected spinal levels, severe other diseases (like diabetes needing daily insulin), or pregnancy are excluded.Check my eligibility
What is being tested?
The study tests whether the Synergy Disc implant is as safe and effective as traditional surgery (ACDF) for treating single-level cervical degenerative disc disease unresponsive to conservative care. Patients will be monitored over two years with evaluations before surgery and several times postoperatively.See study design
What are the potential side effects?
Potential side effects may include typical surgical risks such as infection, pain at the site of operation, nerve damage, problems with the implant like loosening or breakage, difficulty swallowing, hoarseness, and possibly a need for additional surgeries.

Experimental Treatment
Group I: Synergy DiscExperimental Treatment1 Intervention
The Synergy Disc is a cervical disc prosthesis that can be inserted between C3-C7 in skeletally mature patients after anterior discectomy to provide restoration of motion to the functional spinal unit. The Synergy Disc is designed to restoring kinematics to the cervical spine. The Synergy Disc is intended for use in the cervical spine for reconstruction of the disc following a single level discectomy for intractable radiculopathy and/or myelopathy.
