Design outcomes

Primary

Measure	Time frame
The primary outcome parameter is the functionality of the patient that is established by scoring this functionality on several different validated scales. For the group as a whole, including those patients who are lost to follow up, the scales will be the Odom and the Likert scale. For those patients in whom follow up study is possible, the outcome will be established with a combination of the Odom and Likert scale, the Nurick score, the adjusted Japanese Orthopedic Association (JOA) score, the Cooper Myelopathy Scale (CMS), the European Myelopathy Score (EMS) and the Myelopathy Disability Index (MDI). Another primary outcome parameter is the presence of kyphosis of the cervical spine, which will be determined by comparing the pre- and postoperative X-ray of the cervical spine using the Batzdorf classification and the Matsumoto method. Not only the presence of kyphosis, but also the degree of kyphosis will be measured.	—

Secondary

Measure	Time frame
A secundary outcome parameter is the instability of the cervical spine after a cervical laminectomy. Instability will be measured on functionality X-rays of the cervical spine on the follow up visit of the patient. Instability will be determined by considering the alignment of the posterior borders of the corpora.	—
