[Abstract] Objectives: To analyze the relationship between neurological progression following traumatic spinal cord injury and Spinal Cord Compression (SCC) and Spinal Ligamentous Injury (LI) by magnetic resonance imaging. Design: Retrospective observational study. Setting: Spinal Cord Injury Unit (A Coruña, Spain). Participants: Patients were admitted for traumatic spinal cord injury between January 2010 and December 2018 with a magnetic resonance imaging examination performed during the acute phase. Intervention: Evaluation of SCC and LI by magnetic resonance imaging. Outcome measures: Comparisons between neurological examination at admission and discharge were made, assessing ASIA Impairment Scale (AIS) grade and motor score. Results: Data from 296 patients were collected. A relationship between SCC and LI and complete injuries were found (P < 0.001). Improvement of the AIS grade was observed in 31.6% of patients with SCC and 31.3% with LI versus 42.7% and 37.8% of subjects without these complications, respectively. Regarding motor score, patients with SCC had lower mean values at the beginning (46.9 ± 26.8 versus 61.1 ± 29.9 in the control group, P < 0.001), as well as less improvement when assessed by the percentage of change (35.1 ± 37.5% versus 49.4 ± 38.1% in the control group, P = 0.010). Similar results were obtained in cases with LI: mean motor score at admission was 45.9 ± 26.7 versus 54.9 ± 29.4 in the control group (P = 0.014) and the percentage of change was 28.5 ± 37.1% in comparison to 46.0 ± 37.5% (P = 0.001) in the controls. Conclusions: There is a relationship between SCC and LI and complete spinal cord injury. This patient population has lower possibilities of improving their AIS grade and motor score.

[Resumen] Objetivo. Valorar en individuos con lesión medular traumática (LMT) la relación entre la mortalidad y la necesidad de UCI y las alteraciones objetivadas mediante resonancia magnética (RM) precoz, analizando alteraciones parenquimatosas, disrupción de ligamentos vertebrales (DLV) y compresión del cordón medular (CCM). Diseño. Estudio retrospectivo. Ámbito. Hospital de tercer nivel, unidad de lesionados medulares y UCI. Pacientes. Individuos con LMT aguda entre los años 2010 y 2019. Intervenciones. Análisis de RM realizada en las primeras 72 horas. Variables de interés. Ingreso en UCI y mortalidad. Resultados. Recogidos 269 casos. El patrón que se asoció a una mayor mortalidad fue la hemorragia (16,7%) por 12,5% de los edemas a un nivel y 6,5% de los edemas a múltiples niveles (p = 0,125). Lo mismo aconteció con los ingresos en UCI: 69,0% en hemorragia por 60,2% en edema múltiple y 46,3% en edemas cortos (p = 0,018). Con respecto a la CCM, la mortalidad fue del 13,4% con 59,2% de ingresos en UCI por 2,2% y 42,2% de quienes no presentaban compresión (p = 0,020 y p = 0,003). Las cifras de éxitus e ingreso en UCI en los individuos con DLV fueron del 15,0% y el 67,3%, respectivamente, por un 6,2% y 44,4% de los individuos sin DLV (p < 0,001 y p = 0,013). Conclusiones. La presencia de hemorragia medular, CCM y DLV se asoció a una mayor necesidad de UCI. Existe un significativo aumento de la mortalidad en los casos con CCM y DLV., [Abstract] Objective. To assess in individuals with traumatic spinal cord injury (TSCI) the relationship between mortality and need for ICU and early magnetic resonance imaging (MRI), analyzing spinal parenchymal alterations, disruption of vertebral ligaments (DVL) and spinal cord compression (SCC). Design. Retrospective study. Setting. Third-level hospital, Spinal Cord Injury Unit and ICU. Patients. Individuals with acute TSCI between 2010 and 2019. Intervention. Analysis of MRI performed in the first 72 h. Variables of interest. Admission to ICU and mortality. Results. 269 cases collected. The pattern that demonstrated higher mortality was cord hemorrhage (16.7%) for 12.5% of single-level edema and 6.5% of multilevel edema (p = 0.125). The same happened with ICU admissions: 69.0% in hemorrhage, 60.2% in multilevel edema and 46.3% in short edema (p = 0.018). Analyzing CCM, mortality was 13.4% with 59.2% of ICU admissions, for 2.2% and 42.2% of individuals without cord compression (p = 0.020 and p = 0.003). The figures of death and ICU admission among cord injuries with DVL were 15.0% and 67.3%, for 6.2% and 44.4% of the individuals without DLV (p < 0.001 and p = 0.013). Conclusions. The presence of spinal cord hemorrhage, SCC and DVL was associated with a higher admission in ICU. A significant increase in mortality was observed in cases with SCC and DVL.
