Overview
Brief Summary
This study randomizes neck and arm pain patients being treated with discectomy and anterior interbody fusion into two groups: one to receive a new ceramic implant and a control group with a more traditional plastic implant. The study will measure and compare pain and disability improvement with the two products over a period of two years. The fusion status will also be judged with plane x-rays and one CT scan.

Eligibility Criteria
Inclusion Criteria
- •Age 18 75 years

- •Ability and willingness to comply with project requirements
- •Written informed consent given by the subject or the subject's legally authorised representative
Exclusion Criteria
- •Previous cervical surgery (either anterior or posterior)
- •Increased motion on dynamic studies (\> 3 mm)
- •Severe segmental kyphosis of the involved disc level (\> 7 degrees)
- •Patient cannot be imaged with MRI
- •Neck pain only (without radicular or medullary symptoms)

Outcomes
Primary Outcomes
Neck Disability Index
Time Frame: 24 months post-op
The change in the Neck Disability Index compared to the pre-op value for each group will be compared. Neck disability index is a unitless measure from zero (no disability) to 100 (absolute disability). Change is calculated as the pre-op value minus the 24 month value. A negative difference indicates that the patient is more disabled at 24 months.
Secondary Outcomes
- Fusion Status(3 mo., 6mo., 12 mo., 24 months)
