Validation of the TLICS and AOSpine injury score for surgical management of paediatric traumatic spinal injuries.

Fractures of the thoracolumbar spine in children are rare. Consequently, classification systems providing detailed treatment recommendations as already established in adults are still lacking in the paediatric population. We aimed to evaluate the validity and reliability of the thoracolumbar injury classification and severity score system (TLICS) and the AOSpine injury score in paediatric patients presenting with a traumatic fracture of the thoracolumbar spine. Patients younger than 18 years presenting with a traumatic thoracolumbar fracture at a large academic trauma centre between 2010 and 2020 were included retrospectively. Demographic and clinical data were retrieved from electronic medical reports. The AOSpine injury score and TLICS were calculated using plain radiography, magnetic resonance imaging, and/or computed tomography. Sixty patients with 167 fractures were included. Surgical treatment was performed in 14 patients. The mean AOSpine injury score was 1.49 ± 2.0, the mean TLICS was 1.32 ± 1.65. A significant correlation between the classification systems was found (Spearman r = 0.975, p < 0.001). Interrater reliability analysis revealed Kappa values of 0.868 for the TLICS and 0.860 for the AOSpine injury score (p < 0.001). Contingency table analysis showed a sensitivity of 1.00 and specificity of 0.94 for the AOSpine injury score and a sensitivity of 0.90 and specificity of 0.90 for the TLICS in predicting the performed treatment. Our results confirm that the TLICS is a valid classification system for determining treatment decisions in paediatric patients and show slightly higher accuracy of the AOSpine injury score as well as high interrater reliabilities for both classification systems.

Superiority of thoracolumbar injury classification and severity score (TLICS) over AOSpine thoracolumbar spine injury classification for the surgical management decision of traumatic spine injury in the pediatric population.

Thoracolumbar fractures are the most common kind of spine injury in children. Several types of spine injury can occur, and for this reason, treatment algorithms have been put in place for the management of these patients. At present, the thoracolumbar injury classification and severity score system (TLICS) and the thoracolumbar AOSpine injury score (AOSpine score) aimed at providing treatment recommendations. We aimed to assess the reliability, in children, of the TLICS scoring and AOSpine scoring systems, and to define the superiority of one of the methods of scoring, to spread its use in routine clinical management in the pediatric spine trauma. A retrospective chart review of consecutive children admitted to a Level 1 trauma center for traumatic thoracolumbar fractures, between 2006 and 2019, was performed. We compared the management we performed in clinical practice in children with spine trauma, to the decisional algorithms based on the TLICS and AOSpine scores. According to these scores, surgical treatment should be performed when the TLICS score ≥ 5 and the AOSpine score > 5; and surgical or conservative treatment was considered reasonable when the TLICS score = 4 and the AOSpine score = 4 or 5. Surgical indications were based on the clinical status, the anatomy of the fracture, and the risk of sagittal imbalance of the growing spine. Fifty-four patients met the inclusion criteria. We demonstrated that both the AOSpine score and the TLICS scores had a significant correlation for surgical management decision of spine trauma (p < 0.0001). We found a high concordance between surgical decision making in the pediatric clinical practice and the TLICS score. In our pediatric cohort, there were significantly more patients with TLICS ≥ 5 (n = 47, 87%) than with AOSpine score > 5 (n = 26, 46%, p < 0.0001). There were significantly more patients with TLICS ≥ 4 (n = 53, 98%), than with AOSpine score ≥ 4 (n = 42, 77%, p = 0.001). ConclusionsThe TLICS score was significantly more appropriate than the AOSpine score, for the surgical treatment decision in children, especially when considering the future risk of sagittal imbalance.

The AOSpine thoracolumbar spine injury classification system: A comparative study with the thoracolumbar injury classification system and severity score in children.

There is no uniform classification in the pediatric population for thoracolumbar (TL) fractures, nor any operative guidelines. This study evaluates the AOSpine TL spine injury classification in the pediatric population and compares it to the thoracolumbar injury classification system (TLICS), which has previously been validated in pediatric spine trauma. Twenty-eight patients with operative TL injuries were identified from 2006 to 2016. Inclusion criteria included available imaging, operative records, age <18, and posterior approach. Each case was classified by AOSpine TL spine injury classification and TLICS. Each classification was compared to documented intraoperative posterior ligamentous complex (PLC) integrity as well as each other. Utilizing the AOSpine TL spine injury classification, 7 patients had type A injuries, 15 patients had type B injuries, and 6 patients had type C injuries; 21 patients had injuries classified as involving the PLC. Using TLICS, 16 patients had burst fractures, 6 patients had distraction injuries, and 6 patients had translation injuries; 21 patients had injuries classified as involving the PLC. Spearman correlation analysis substantiated convergence of AOSpine TL spine injury classification scores to TLICS scores (r = 0.75; 95% confidence interval, CI = 0.51 to 0.98; P < .001). Concordance between PLC integrity by each classification and intraoperative evaluation was 96% (27/28) of cases (k = 0.91; 95% CI = 0.73 to 1.08). Neurologic status was 100% concordant between the AOSpine TL spine injury classification and TLICS. There is high statistical correlation between the AOSpine TL spine injury classification and TLICS, and to intraoperative evaluation of the PLC, suggesting that the AOSpine TL spine injury classification is applicable to the pediatric population.
