“…The diagnosis was selected using ICD-9 (other paralytic syndromes 344.0-344.9; fracture of vertebral column without mention of SCI 805.0-805.5; fracture of the vertebral column with SCI 806.0-806.6; dislocation of vertebra 839.4; SCI without evidence of spinal bone injury 952.0-952.9) or ICD-10 (fracture of vertebra S12.0-S12.9, S22.0, S32.0, S32.9; dislocation, subluxation of vertebrae, traumatic rupture of intervertebral disc S13.0-S13.1, S23.0-S23.1, S33.0-S33.1; injury of nerves and spinal cord S14.0-S14.9, S24.0-S24.2, S34.0-S34.2) based on the registry data, we excluded patients with preexisting disability (de ned as Glasgow Outcome Score [GOS] <4 before the injury), traumatic brain injury (TBI) (de ned as traumatic cerebral edema, diffuse/focal TBI, epidural hemorrhage, traumatic subdural hemorrhage, traumatic subarachnoid hemorrhage using ICD-9 854.0, 851.0-852.5; ICD-10 S06.1-S06.9), incomplete data on immobilization, Injury Severity Score (ISS), Revised Trauma Score (RTS) at the ED, functional outcome at discharge or prehospital time interval. We excluded patients with TBI because the prevalence of concomitant TBI in patients with an SI can be as high as 32.5% 21 , and we could not differentiate whether the disability resulted from TBI or SI.…”
