A Multicenter Registry-Based Study Across the Spectrum of Degenerative Cervical Myelopathy

This is a multicenter, prospective, longitudinal, observational registry-based study of degenerative cervical myelopathy (DCM) across the full disease spectrum, linked to a disease-specific biobank. The study will enroll adults with non-myelopathic degenerative cervical cord compression, including asymptomatic degenerative cervical cord compression with or without radiculopathy, as well as patients with mild, moderate, or severe DCM. The study does not assign treatment or interfere with real-world clinical decision-making. All participants will undergo standardized baseline assessment, scheduled follow-up, and event-driven supplemental data collection. Core data include demographic information, comorbidities, disease characteristics, neurological examination, objective functional tests, patient-reported outcomes, cervical MRI findings, treatment pathway, treatment changes, adverse events, and long-term clinical outcomes. In participating centers, standardized biospecimen collection will be performed to support nested biomarker, immune, imaging, electrophysiological, and traditional Chinese medicine syndrome substudies. The main objective is to establish a standardized multicenter registry platform covering non-myelopathic degenerative cervical cord compression and mild, moderate, and severe DCM; to describe clinical trajectories, imaging evolution, treatment pathways, and long-term outcomes; and to identify factors associated with disease deterioration and functional prognosis.

M6-C Post Approval Study (PAS)

The M6-C Post Approval Study is a long term follow-up study of subjects previously enrolled and treated in the M6-C Artificial Cervical Disc IDE Study.
