![]() ![]() This latter feature depends on intra- and interobserver agreement In addition, it must be feasible, reliable, and reproducible. A good classification system must have simple language and provide reliable information for correct propaedeutics. Ankle fractures diagnosis is based on clinical history, physical examination, and regional image evaluation, usually with simple ankle radiographs in anteroposterior (AP), lateral and true AP (with 20° internal rotation) views.Ĭlassification systems are important tools for prognosis definition and to guide the most appropriate treatment. ![]() When subjected to deforming forces, mainly rotational, this complex bone-capsule-ligament anatomy suffers a number of injuries that must be studied. The demographic transition resulted in an approximately 3-fold increase in the incidence of these fractures in elderly patients for the last 30 years.Īt the ankle joint, the talus body fits into the malleolar clamp, functioning as a modified trochlea, and it is stabilized by lateral, medial and syndesmotic ligament complexes. Level of Evidence II, Diagnostic Studies – Investigating a Diagnostic TestĪnkle fractures comprise ∼ 10% of all human body fractures these injuries are more common in women and are associated with obesity and smoking. The Danis-Weber classification presented the highest reproducibility among instruments and the evaluator's little experience had no negative influence on the reproducibility of ankle fracture classifications. The Danis-Weber classification showed, on average, a significantly higher degree of agreement than the remaining classification systems ( ≤ 0.0001) for the Danis-Weber classification. Moderate to excellent interobserver agreement was highly significant ( Intraobserver analysis alone had a significant agreement in all classifications. Student t-tests for paired samples were applied to detect significant differences in the degree of interobserver agreement between instruments. Intra- and interobserver agreement was analyzed using the weighted Kappa coefficient. ![]() All images were evaluated by 11 evaluators at different stages of professional training (5 residents and 6 orthopedic surgeons), at 2 different times. ![]() The present study aims to analyze the intra- and interobserver reproducibility of the Lauge-Hansen, Danis-Weber, and Arbeitsgemeinschaft für Osteosynthesefragen (AO) classifications for ankle fractures, and the influence of evaluators training stage in these assessments.Īnteroposterior (AP), lateral and true AP radiographs from 30 patients with ankle fractures were selected. ![]()
