Traumatic Cervical Spinal Cord Injury: Correlation of Imaging Findings with Neurological Outcome

Background Traumatic spinal cord injury (TSCI) is extremely costly to the global health system. Due to the significant frequency rate of traumatic cervical spinal cord injuries (TCSCI), the possible association between imaging findings and clinical outcome is not yet clear. In this study, we quantified maximum spinal cord compression and maximum cord swelling following TCSCI and determined the relevance of imaging findings to clinical outcome in patients. Materials and Methods This retrospective cohort comprises 20 patients with TCSCIs (C3-C7), classified as complete, incomplete, and no SCI, who were treated at the Poursina Hospital, Iran, from 2018 to 2020, and underwent spinal surgery. Patients with penetrating injuries and multiple trauma were excluded. Imaging findings revealing spinal cord compression, swelling, and canal stenosis, based on the American Spinal Injury Association (ASIA) Impairment Scale (AIS) grades of patients from hospital admission (up to 48 hours after injury) and improvement of postoperative neurological symptoms (6–12 months) were evaluated. Results Cord compression (p = 0.05) and cord swelling (p = 0.02) were significantly related to predictive neurological outcomes in all cases. Evaluation with AIS at hospital admission and at 6 to 12 months postoperatively showed significant correlation with fracture type (p = 0.05) and the longitudinal length of the intramedullary lesion (IML); p = 0.01, respectively. Conclusion According to the results obtained in this study, it may be concluded that there is a significant association between cervical spinal cord compression and swelling, and clinical outcomes in patients with complete, incomplete, and no SCI.
