Cervical Spondylotic Myelopathy Surgical Trial

Ventral decompression and fusion will be performed using a multi-level discectomy (including partial or single level corpectomy) with fusion and plating. Allograft will be used at each disc space and all compressive osteophytes will be removed using the operating microscope. Fixation will be performed with rigid, semi-constrained, or dynamic titanium plates to optimize fusion and minimize complications.

Dorsal decompression and fusion will be performed using midline cervical laminectomy with the application of lateral mass screws and rods for rigid fixation. All surgeons will use local bone and allograft as needed to perform a lateral mass fusion, which typically will include one level rostral to the levels decompressed.

Laminoplasty will be performed using an open-door approach with the application of plates and screws at each treated level. Ceramic or allograft laminar spacers (surgeon's choice) can be used with plates and screws to expand the canal diameter.
