Introduction: Since 2011 the Swedish Fracture Register (SFR) has collected information on fracture epidemiology, treatment and outcome. More than 112 000 fractures, including 11 600 ankle fractures, have been registered so far. The accuracy of the classification is crucial when using the register in future research and quality improvement of care.
