Burns SP, Weaver F, Chin A, Svircev J, Carbone L. Cervical stenosis in spinal cord injury and disorders. The journal of spinal cord medicine. 2016 Jul 1; 39(4):471-5.
CONTEXT/OBJECTIVE: The purpose of this study was to characterize etiologies of spinal cord injury and disorders (SCI/D) in persons with and without cervical stenosis/spondylosis (CSS) and to describe clinical characteristics and underlying comorbidities in these populations. DESIGN AND SETTING: We reviewed administrative data for 1954 Veterans who had onset of traumatic or non-traumatic tetraplegia during FY 1999-2007. This included 1037 with a diagnosis of CSS at or in the two years prior to SCI onset of SCI/D and 917 without a diagnosis of CSS. OUTCOME MEASURES: Demographics, etiologies of SCI/D and comorbidities by CSS status. RESULTS: Veterans with SCI/D and CSS were older, more likely to have incomplete injuries and more likely to be Black than those with SCI/D and no CSS. Of patients with traumatic etiologies for SCI, 35.1% had a diagnosis of CSS at the time of or in the 2 years prior to SCI onset. Of those with tetraplegia due to falls, 40.0% had CSS, whereas for other known traumatic etiologies the percentages with CSS were lower: vehicular (25.0%); sports (16.1%); and acts of violence (10.2%). Total comorbidity scores measured by the Charlson co morbidity index and CMS Hierarchical Condition Category (CMS-HCC) were higher in those with CSS and SCI/D compared to those with SCI/D without CSS (P? < 0.0001 respectively). CONCLUSIONS: CSS is commonly present in patients with new traumatic tetraplegia. Falls are a particularly important potentially modifiable risk for SCI in patients with CSS.
