Abstract:
Objective To determine sensitive indices for defining degenerative cervical spinal canal stenosis(DCSCS) with a new radiograghic measurement method. Methods One hundred normal lateral radiographs of the cervical spine were divided into two groups according to ages. The following indices were measured or calculated: sagittal diameter of spinal canal(a), sagittal diameter of cervical body(b), sagittal diameter of edge or degenerative cervical body(c), cervical spinal canal ratio[(a/b),CSCR] and effective cervical spinal canal ratio [(a+b-c)/c,ECSCR]. The comparisons of these indices between two groups were performed to select the most sensitive index for clinical reference. Results There was no significant difference between the two age groups in terms of a, b and a/b. The comparison of c and (a+b-c)/c between two age groups showed significant difference at the level of C4,C5 and C6 (P
