The purpose of this study is to evaluate the safety and effectiveness of the investigational implant (INFUSE® Bone Graft/PEEK Interbody Spacer/Anterior Cervical Plate) as a method of facilitating spinal fusion at a single level from C3-C7 in patients with symptomatic cervical degenerative disc disease.
This pivotal clinical trial is being conducted to evaluate the safety and effectiveness of INFUSE® Bone Graft with the PEEK Interbody Spacer and Anterior Cervical Plate in patients with symptomatic cervical degenerative disc disease (DDD). The implant under investigation in this clinical trial is INFUSE® Bone Graft, the PEEK Interbody Spacer, and Anterior Cervical Plate. The device will be implanted using an anterior surgical approach. Safety and effectiveness data for patients in this study will be compared to that of historical controls. Historical control data will be taken from the control arms of the following Medtronic studies: (1) the Artificial Cervical Disc (also known as PRESTIGE® Cervical Disc System) pivotal IDE trial (NCT00642876) and (2) the BRYAN® Cervical Disc System pivotal IDE trial (NCT00437190).

Rate of Overall Success
Rate of overall success is reported as the percentage of participants who met all of the following criteria: 1. fusion at the treated level; 2. pain/disability (Neck Disability Index) success; 3. neurological status success; 4. no serious adverse event classified as "implant associated" or "implant/surgical procedure associated;" 5. no additional surgical procedure classified as a "failure."
Time frame: 24 months post-operation
Success Rate of Fusion
Success Rate of Fusion is reported as percent of participants who met the following fusion criteria: 1. Evidence of bridging bone. This is based on the evidence of a continuous bony connection from the superior vertebral body to the inferior vertebral body in at least one of the following areas: lateral, anterior, posterior and/or through the PEEK spacer. 2. No evidence of radiolucency at greater than 50% of the superior or inferior PEEK spacer-vertebra interface. 3. No evidence of motion as defined by ≤ 4º of angular motion (based on flexion-extension lateral plain radiographs).
Time frame: 24 months post-operation
Success Rate of Neck Disability Index
Success rate of Neck Disability Index is reported as the percentage of participants whose neck disability index score met: Pre-treatment Score - Post-treatment Score ≥ 15.
Time frame: 24 months post-operation
Success Rate of Neurological Status
Success rate of neurological status is reported as the percentage of participants who met neurological success defined as maintenance or improvement in all sections (motor, sensory, and reflexes) for the time period evaluated. In order for a section to be considered a success, each element in the section must remain the same or improve from the time of the preoperative evaluation to the time period evaluated.
Time frame: 24 months post-operation
