Fig. 4.
Depicted is a case with high disagreement between the classification done by MRI (a: STIR-Sequence, b: T2-Sequence) only and under consideration of both MRI and CT (c). The majority of rater classified this fracture as type OF 4 fracture after evaluating the MRI and re-classified it as type OF 3 fracture under consideration of the additional CT. However, the OF score was 7 and 9 in case of OF type 3 and OF type 4 fracture, respectively. Thus, operative treatment was recommended based on the OF-score regardless of type OF 3 or 4 fracture classification
