Reporting Groups
  Description
Bone Graft Substitute

Subjects will receive anterior cervical discectomy with fusion and instrumentation (anterior plate). Structural allograft ring will be used. The cavity of the ring will be filled with P-15 synthetic osteoconductive bone substitute (investigational device).

P-15 Synthetic osteoconductive bone substitute: Safety and efficacy of synthetic bone substitute used for fusion in spinal surgery

Autologous Bone

Subjects will receive anterior cervical discectomy with fusion and instrumentation (anterior plate). Structural allograft ring will be used. The cavity of the ring will be filled with local autologous bone.

Autologous bone: Local autologous bone will be harvested, milled and placed into the cavity of the structural allograft ring
