Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of the study is to determine the optimal surgical approach (ventral versus dorsal) for patients with multi-level cervical spondylotic myelopathy (CSM). There are no established guidelines for the management of patients with CSM, which slowly causes spinal cord injury in afflicted patients. This study aims to test the hypothesis that ventral surgery (decompressing the spinal cord from the front of the neck) and dorsal surgery (decompressing the spinal cord from the back of the neck) might differ in their overall outcome or major complication rate.
