Radiographical changes and clinical prognosis after cervical laminectomy with posterior instrumented fusion for degenerative cervical myelopathy

In LF, long-segment and short-segment decompression did not produce significant differences in intervertebral foraminal, spinal canal, or spinal cord morphology pre- and postoperative. Neurological improvement was correlated with the postoperative SAS and SCE, but not with other spinal cord, intervertebral foraminal, or spinal canal morphologies. The incidence of postoperative C5P was significantly correlated with preoperative SAP in the spinal canal morphology, making it a potential predictive factor for C5P.
