Thoracolumbar Injury Classification and Severity Score in children: a reliability study

Area of Science:

• Orthopedics
• Pediatric Traumatology
• Spinal Surgery

Background:

• Numerous classification systems exist for thoracolumbar spine injuries.
• The Thoracolumbar Injury Classification and Severity Score (TLICS) is a validated tool for adult patients.
• The reliability of the TLICS in pediatric populations requires further investigation.

Purpose of the Study:

• To evaluate the interrater reliability of the Thoracolumbar Injury Classification and Severity Score (TLICS) in pediatric patients with acute, traumatic thoracolumbar fractures.
• To compare TLICS-determined treatment recommendations with actual treatment received.
• To assess the impact of imaging modalities (CT and MRI) on TLICS reliability and treatment concordance.

Main Methods:

• Retrospective review of medical records for pediatric patients with thoracolumbar fractures.
• Calculation of TLICS scores by five independent raters using CT and MRI data.
• Comparison of TLICS-suggested treatment with actual treatment provided.
• Statistical analysis of interrater reliability using Fleiss' generalized kappa (κ).

Main Results:

• Eighty-one pediatric patients were included (mean age 10.9 years).
• The overall interrater reliability for TLICS treatment suggestion was good (κ = 0.69).
• Interrater reliability decreased when MRI was incorporated into the TLICS calculation (κ = 0.57 for MRI-only vs. 0.73 for CT-only).
• Agreement between TLICS-suggested and actual treatment was poorer with MRI use.

Conclusions:

• The TLICS system demonstrates good interrater reliability for guiding thoracolumbar fracture treatment in pediatric patients.
• Physicians should exercise caution when utilizing MRI findings within the TLICS framework for pediatric surgical decision-making.
• Further research may be needed to refine the TLICS for optimal use in pediatric spinal trauma assessment.
