Eligibility Criteria:
Inclusion Criteria:~1. Age 18-69 years.~2. Diagnosis of radiculopathy or myeloradiculopathy of the cervical spine, with pain, paresthesias or paralysis in a specific nerve root distribution C3 through C7, including at least one of the following:~   * Neck and/or arm pain (at least 30mm on the 100mm VAS scale).~  * Decreased muscle strength of at least one level on the clinical evaluation 0 to 5 scale.~  * Abnormal sensation including hyperesthesia or hypoesthesia; and/or~  * Abnormal reflexes~3. Symptomatic at one or two adjacent levels from C3 to C7;~4. Radiographically determined pathology at one or two adjacent level(s) to be treated correlating to primary symptoms including at least one of the following:~   * Decreased disc height on radiography, CT, or MRI in comparison to a normal adjacent disc.~  * Degenerative spondylosis on CT or MRI.~  * Disc herniation on CT or MRI;~5. Neck Disability Index Score of ≥15/50 or ≥30%;~6. Unresponsive to non-operative, conservative treatment (rest, heat, electrotherapy, physical therapy, chiropractic care and/or analgesics) for:~   * Approximately six weeks from radiculopathy or myeloradiculopathy symptom onset; or~  * Have the presence of progressive symptoms or signs of nerve root/spinal cord compression despite continued non-operative conservative treatment.~Note: Not a complete listing~Exclusion Criteria:~1. Reported to have an active systemic infection or infection at the operative site;~2. Reported to have a history of or anticipated treatment for active systemic infection, including HIV or Hepatitis C;~3. More than one immobile vertebral level between C1 to C7 from any cause including but not limited to congenital abnormalities and osteoarthritic spontaneous fusions;~4. Previous trauma to the C3 to C7 levels resulting in significant bony or disco-ligamentous cervical spine injury;~5. Reported to have had any prior spine surgery at the operative level;~6. Reported to have had prior cervical fusion procedure at any level;~7. Axial neck pain in the absence of other symptoms of radiculopathy or myeloradiculopathy justifying the need for surgical intervention;~8. Disc height less than 3mm as measured from the center of the disc in a neutral position and disc height less than 20% of the anterior-posterior width of the inferior vertebral body;~9.
