1.Primary Outcome
Title Radiologic Fusion
Hide Description Successful fusion was based on roentgenographic examination showing: evidence of bridging trabecular bone between the involved motion segments, translational motion <3mm, and angular motion <5 degrees. If there was a lack of evidence of fusion on 12 month plain x-ray examination, a CT-scan was performed and final determination of the fusion status was made using the CT reading. The criteria for fusion on CT scans were: trabecular bone formation patterns within the intervertebral disc space and bridging bone formation that crosses the interspace.
Time Frame 12 months
Hide Outcome Measure Data

2.Primary Outcome
Title Change in of the Overall Neck Disability Index (NDI) Score From Baseline.
Hide Description The NDI consists of ten items addressing functional activities (personal care, lifting, reading, work, driving, sleeping, recreational activities), pain intensity, concentration and headache. For each item, there are six potential responses, describing increasing degrees of disability (no disability = 0 to total disability = 5). An overall NDI score, out of 100, is calculated by adding up the scores for each item and multiplying by two. A higher NDI score indicates greater disability.

3.Primary Outcome
Title Neurologic Success
Hide Description The neurological endpoint is a binary variable. Neurologic success was assessed in the motor, sensory and reflex domains specific for the cervical spine as follows: maintenance or improvement of motor function in the elbow flexors (i.e. biceps muscle), elbow extensors (i.e. triceps muscle) and wrist extensors of both arms; maintenance or improvement of sensory function of both arms; maintenance or improvement of reflexes of both arms as measured at biceps tendon, triceps tendon and brachioradialis (supinator) reflex AND absence of Babinski reflex (if not present prior to surgery). Worsening of neurological status (neurological failure) was defined as a permanent decline in the subject's neurological status based on adjudication of accumulated neurological data by an independent blinded evaluator.
