Cervical degenerative spondylolisthesis: analysis of facet orientation and the severity of cervical spondylolisthesis

摘要

BACKGROUND CONTEXT: Previous studies have shown an association between the degree of cervical degenerative spondylolisthesis (DS) and spinal cord conditions of the cervical spine. However, there is no information available on the association between the severity of cervical DS and the orientation of the cervical facet joints. This study examined the association between the severity of cervical DS and facet tropism.
