BACKGROUND Two of the most commonly used classifications for the posterior malleolus fracture are Haraguchi and Bartoníček. Both classifications are based on the morphology of the fracture. This study makes an inter- and intra-observer agreement analysis of the mentioned classifications. METHODS 39 patients with ankle fractures who met inclusion criteria were selected. All the fractures were analyzed and classified twice by each of the 20 observers using Bartoníček and Haraguchi's classifications, with a window period of at least 30 days between the two rounds. RESULTS Analysis was made by Kappa coefficient (ƙ). The global intraobserver value was ƙ = 0.627 in the Bartoníček classification and ƙ = 0.644 in the Haraguchi one. The first round global interobserver ƙ = 0.589 (0.574-0.604) on the Bartoníček classification and ƙ = 0.534 (0.517-0.551) on the Haraguchi one. Second round coefficients were ƙ = 0.601 (0.585-0.616) and ƙ = 0.536 (0.519-0.554), respectively. The best agreement was when there was involvement of the posteromedial malleolar zone with ƙ = 0.686 and ƙ = 0.687 in Haraguchi II and ƙ = 0.641 and ƙ = 0.719 in Bartoníček III. No differences were observed in Kappa values when an experience-based analysis was made. CONCLUSIONS Bartoníček and Haraguchi classifications of the posterior malleolus fracture have both substantial intraobserver agreement but moderate to substantial agreement in interobserver analysis.

D015203 Reproducibility of Results The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.

D015588 Observer Variation The failure by the observer to measure or identify a phenomenon accurately, which results in an error. Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material).
