Primary | Number of Participants With Differing Severity of Adjacent Level Ossification | Qualitatively assessed by an independent Radiologist using lateral radiographs Grade 0 - None Grade 1 - Mild (if the ossification extended across <50% of the disc space) Grade 2 - Moderate (if the ossification extended across = 50% of the disc space) Grade 3 - Severe (if there is complete bridging of the adjacent disc space) | 24 Months | |
Secondary | Change in Neck Disability Index (NDI) | The Neck Disability Index (NDI) is a patient-completed, condition-specific functional status questionnaire with 10 items including pain, personal care, lifting, reading, headaches, concentration, work, driving, sleeping and recreation. Each section is scored on a 0 to 5 rating scale, in which zero means 'No pain' and 5 means 'Worst imaginable pain', with the points summed to a total score. The test can be interpretated as a raw score, with a minimum score of 0 and a maximum score of 50. A higher score indicates more patient-rated disability. To use the NDI for patient decisions, a clinically important change was calculated as 5 points. | 24 Months |
