Fratura diafisária do fêmur: reprodutibilidade das classificações AO-ASIF e Winquist
Acta Ortopedica Brasileira(2010)
摘要
Objective: To evaluate inter-observer reproducibility of AO / ASIF and Winquist-Hansen classifications for shaft fractures of the femur in adults. Methods: 50 anterior-posterior and lateral radiographs were randomly selected, of adult patients with diaphyseal fracture of the femur. The radiographs were analyzed by 5 observers-a member of the Brazilian Society of Orthopedic Trauma, a radiologist and 3 residents. To assess the concordance between these classifications, we used the statistical index Kappa (K). Results: In all analyses, we observed a statistically significant correlation coefficient between observers (p <0.05) and according to the criteria of Landis and Koch, they were ranked as good (values of 0.61 to 0.80) or very good (values above 0.80). Conclusion: The AO rating and Winquist present a high rate of concordance between observers for shaft fractures of the femur in adults.
