简要总结
DTRAX Graft is used to relieve nerve pressure in the neck in order to provide relief for Cervical Degenerative Disc Disease. This study is being conducted to determine the effectiveness of the graft, and to find out whether or not it provides better results or faster healing than traditional ways of performing surgery for Cervical Degenerative Disc Disease.

结局指标
主要结局
Gather clinical outcome data on DTRAX Graft.
时间窗: Baseline throughout 12 months post-operatively
Clinical outcome data will be collected using the Neck Disability Index (NDI), Visual Analogue Scale (VAS), and a quality of life questionnaire.
次要结局
- Safety information will be evaluated by collecting the type, frequency, severity, device, and procedure-relatedness of adverse events.(Baseline throughout 12 months post-operatively)
