Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Baseline and short-term functional status was scored via a questionnaire, the Nurick outcome scale. Long-term follow-up functional status was scored by means of a set of questionnaires: The Nurick outcome scale, the adjusted JOA scale and Neck disability index. Preoperative fluoroscopy and MRI of the cervical spine were evaluated. The fluoroscopy was used to determine the presence of kyphosis and segmental instability using the methods of, Matsumoto and Knopp respectively. The preoperative MRI was evaluated to confirm the diagnosis of spondylotic myelopathy, to count the number of stenotic levels and to assess the presence of any lesions in the spinal cord. Moreover, the compression ratio of all cervical levels was measured by dividing the sagittal diameter of the medulla by the transverse diameter | — |
Secondary
| Measure | Time frame |
|---|---|
| At long-term follow-up a lateral and a flexion-extension fluoroscopy was obtained and evaluated for the presence of kyphosis and segmental instability. Anteroposition of more than 2 mm of two adjacent corpora occurring upon motion was considered as segmental instability. In addition, prospective data of the perceived recovery were retrieved from a questionnaire at long-term follow-up, at least 3 year postoperatively | — |
