Brief Summary:

The purpose of this research is to test if that combining bone marrow aspirate (removing bone marrow with a needle) concentration with locally harvested (collected) autograft (patient's own bone from another part of the body) for use as the bone graft results in equal rates of a successful procedure (fusion), as compared to current best practice in high-risk patients undergoing posterior cervical fusion.

Hypothesis: Bone marrow aspirate concentration combined with locally harvested autograft results in equivalent rates of bony fusion, as compared to current best practice in high-risk patients undergoing posterior cervical decompression and fusion.

Primary Outcome Measures :
  1. Rate of Fusion [ Time Frame: 24 months ]
    Rate of fusion - (6, 12, and 24 months) Rate of fusion will be assessed by flexion extension X-rays at routine follow-up, translation method (<2mm) and/or by computed tomography (CT) scan at 2 year post-operatively.


Secondary Outcome Measures :
  1. Physical and mental health from subject's point of view [ Time Frame: 24 months ]
    Short Form 36 (SF-36) is a profile of functional health and well-being scores as well as psychometrically-based physical and mental health summary measures and a preference-based health utility index.

  2. Neck pain affects every day activities [ Time Frame: 24 Months ]
    Questionnaire that helps determine how a subject's neck pain affects their ability to manage every day activities.
