“…The increase in agreement between the two sessions is attributed to the value of additional clinical information and the increased level of agreement between the observers who became more familiar with the system. Our values in the second session were similar to results obtained by Oner et al utilizing CT (0.35 -slight) and MRI (0.39 -moderate) in the evaluation of thoraco-lumbar fractures of 53 patients [17]. The mean intra-observer agreement T1 -T9 11 1 26 T10 -L2 14 30 57 L3 -L5 3 [3].…”

“…The mean levels of agreement of the AO-type classification for both the inter-and intra-observer agreement in this study were comparable with those utilizing CT and MRI in the study by Oner et al [17]. There was some improvement in inter-observer agreement when compared with the study by Blauth et al utilizing radiographs and CT [3].…”

“…Differentiation between type A and non-type A (B and C fractures) depends on disruption of the posterior ligamentous complex (the only exception being type B3.1.1). Oner et al [17] and Blauth et al [3] recommended the use of MRI to assist with the evaluation of posterior injury. The difficulty in using MRI is that no clear guidelines regarding MRI findings are incorporated in the original classification as stated by Oner et al [17].…”

“…Appendicular skeleton classification systems have been shown to have a poor to moderate intra-observer reproducibility and interobserver reliability [1,2,7,9,11,15,16,18,19]. There are relatively few studies assessing the reproducibility of thoracolumbar fracture classification systems [3,17].…”

“…Previous studies assessing the reproducibility of the AO-classification have suggested the addition of MRI to increase the level of agreement regarding the type classification [3,17]. The rationale of these proposals was based on the importance of posterior element involvement in the AO-classification.…”

This study was designed to assess the inter-observer reliability and intra-observer reproducibility of standard radiographic evaluation of 150 thoraco-lumbar fractures using the AO-classification. The influence of clinical information on agreement levels was also evaluated. Six observers (two junior and four senior residents) evaluated the radiographic images. The injuries were classified by each observer as either type A, B or C according to the AOclassification system and the levels of agreement were documented. After 3 months the injuries were again classified with the addition of the clinical findings of each patient and the level of agreement evaluated. The level of agreement was measured using Cohen's j-test. The overall inter-observer agreement was rated as fair (0.291) in the first session and moderate (0.403) in the second. Intra-observer values ranged from slight (0.181) to moderate (0.488). The increased level of agreement in the second session was attributed to the value of additional clinical information, the learning curve of the junior residents and the simplicity of the classification.
