Accepts healthy volunteers: no
Observational model: COHORT
Time perspective: PROSPECTIVE
Sampling method: NON_PROBABILITY_SAMPLE
Study population: People over the age of 21 diagnosed with cervical degenerative disc disease and for whom the Synergy Disc device is an option (prospective cohort) or has already been implanted (retrospective cohort).

Brief summary: This is a real world data collection observational study at a single site. There are both prospective and retrospective cohorts. The study will examine the safety and effectiveness of the Synergy cervical disc system in patients with degenerative cervical disc disease.


Eligibility criteria: Inclusion Criteria:

1. Age 21 or above at the time of the surgery.
2. Have had (retrospective cohort) or the decision has been made to have (prospective cohort) the Synergy Disc implanted
3. Skeletally mature patients for reconstruction of the disc from C3-C7 following a single or multiple level discectomy for intractable radiculopathy
4. Intractable radiculopathy and/or myelopathy with at least one of the following producing symptomatic nerve root and/or spinal cord compression:

   1. herniated disc and/or osteophyte formation
   2. Symptomatic nerve root and/or spinal cord compression documented by patient history (arm or neck pain and/or neurologic deficit) and imaging (CT, MRI, x-rays, etc.)
   3. Failed a minimum of 6 weeks conservative treatment
5. Written informed consent given by subject
