Abstract

Background

Classification of ankle fracture is important when deciding for operative or conservative treatment. This study rates the reproducibility of ankle stability assessment and compares it with the classification by Lauge-Hansen and Arbeitsgemeinschaft für Osteosyntesefragen (AO) in adult patients with primary ankle fractures.

Methods

A total of 496 consecutive ankle fractures were included, and the X-ray images were reviewed 2 times by 2 medical students, 2 residents, and 1 consultant in orthopedic traumatology. The raters were blinded to each other and to their own results. Unweighted Kappa statistics were used to assess reproducibility.

Results

Overall mean (95% CI) interrater Kappa results were 0.65 (0.64; 0.68) for Lauge-Hansen, 0.62 (0.60; 0.63) for AO and 0.61 (0.57; 0.62) for the stability assessment. The intrarater results ranged from a mean Kappa of 0.64–0.80 for the medical students, 0.65–0.81 for the residents and 0.82–0.84 for the consultant.

Conclusion

The stability assessment has substantial to almost-perfect agreement which is comparable to the Lauge-Hansen and AO classifications.
