|Experimental: INFUSE™ Bone Graft/CORNERSTONE-SR™||
Device: INFUSE™ Bone Graft/CORNERSTONE-SR™ /ATLANTIS™
Cornerstone-SR™ allograft bone containing recombinant human Bone Morphogenetic Protein (rhBMP-2) soaked into an absorbable collagen sponge (ACS) used in conjunction with ATLANTIS™ anterior cervical plate system.
|Active Comparator: Autogenous bone/CORNERSTONE-SR™||
Device: Autogenous bone/CORNERSTONE-SR™ /ATLANTIS™
Cornerstone-SR™ allograft bone packed with autogenous iliac crest bone graft used in conjunction with ATLANTIS™ anterior cervical plate system.
Other Name: Autograft
Primary Outcome Measures :
- Fusion [ Time Frame: 24 month ]
Fusion is defined as:
- No evidence of motion as defined by: less than 4° difference in angular motion between flexion and extension as seen on the lateral flexion/extension radiographs.
- No radiolucency greater than 2mm of thickness covering more than 50% of superior or inferior graft surface.
- Evidence of bridging trabecular bone.
- Pain/Disability Status [ Time Frame: 24 month ]The self-administered Neck Disability Index will be used. Success for each individual patient will be defined as pain/disability improvement postoperatively according to the following definition: Preoperative Score - Postoperative Score >= 15
- Neurological Status [ Time Frame: 24 month ]Neurological status will be assessed preoperatively and postoperatively using a comprehensive neurological status scale.
Secondary Outcome Measures :
- Time to fusion [ Time Frame: 24 month ]
- Hip (Donor Site) Pain [ Time Frame: 24 month ]
- General Health Status (SF-36) [ Time Frame: 24 month ]
- Pain Status (neck pain, arm pain) [ Time Frame: 24 month ]
- Patient Satisfaction [ Time Frame: 24 month ]
- Patient Global Perceived Effect [ Time Frame: 24 month ]
