Reliability of the radiographic variables in the International Spinal Cord Injury Spinal Column Injury Basic Data Set...

Area of Science:

• Spinal Cord Injury Research
• Radiology
• Orthopedic Surgery

Background:

• Standardized data collection is crucial for spinal cord injury (SCI) research.
• Existing classification systems may have limitations in radiological variable assessment.
• The International SCI Spinal Column Injury Basic Data Set aims to standardize injury descriptions.

Purpose of the Study:

• To evaluate the intra- and interrater reliability of radiological variables within the International SCI Spinal Column Injury Basic Data Set.
• To compare the reliability of the SCI data set with the established Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification system.

Main Methods:

• A reliability study involving two international observers assessing radiological variables.
• Data collected from surgically treated spine trauma patients at a regional SCI referral center.
• Statistical analysis using Cohen's kappa (κ) coefficients for agreement assessment.

Main Results:

• The International SCI Spinal Column Injury Basic Data Set demonstrated substantial intra- and interrater reliability (κ=0.67-0.97).
• AO classification showed moderate-to-substantial intrarater reliability (κ=0.57-0.75) and substantial interrater reliability (κ=0.67-0.69).
• No significant difference in agreement was found between the SCI data set and AO classification.

Conclusions:

• The radiological variables of the International SCI Spinal Column Injury Basic Data Set are reliably assessed.
• The SCI data set's reliability is comparable to the AO classification system.
• Adoption of the SCI data set can enhance global spinal column injury description and data comparability.
