Arms Assigned Interventions
Experimental: 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 investigational device (P15).
Device: P-15 Synthetic osteoconductive bone substitute
Safety and efficacy of synthetic bone substitute used for fusion in spinal surgery
Other Name: i-Factor
Active Comparator: 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.
Other: Autologous bone
Local autologous bone will be harvested, milled and placed into teh cavity o fthe structural allograft ring

Detailed Description:

Anterior Cervical Discectomy and Fusion (ACDF) is a common surgical treatment option for symptomatic degenerative cervical disk disease in patients who fail conservative treatment. i-FACTOR bone graft is a unique anorganic bone mineral (ABM) and small peptide, P-15™. P-15 is a synthetic fifteen amino acid polypeptide that mimics the cell-binding domain of Type I human collagen and is responsible for osteogenic cell attachment via alpha2-beta1 integrins.

This is randomized, controlled, multi-center, prospective FDA IDE study conducted to assess the safety and effectiveness of i-FACTOR bone graft (Cerapedics, Inc. Westminster, CO) in patients treated with single level ACDF. Patients received i-FACTOR bone graft or local autologous bone inside a structural allograft.
