We evaluated patients after laminoplasty for more than 10 years. We were able to follow up on 38 patients via telephone. Twenty-six patients were men and 12 were women. Thirty patients had cervical spondylotic myelopathy (CSM), and 8 had ossification of posterior longitudinal ligament (OPLL).
We examined the Xp of the cervical spine of 13 patients who were able to visit our hospital. After cervical spine operation on these patients, the transverse distance of the spinal canal increased and kyphosis decreased. The ROM of the total cervical spine also decreased, and no new displacement was seen.
Generally, though the death rate of patients after operation is relatively high, the JOA score rate of improvement is relatively high.
