Validation of the Classification of Leonetti and Tigani in Tibial Pilon Fractures Through Resident Doctors in Traumatology and Orthopedics and Foot and Ankle Fellows
Main Article Content
Abstract
Materials and Methods: 54 patients with 54 tibial pilon fractures were evaluated retrospectively. Patients were studied using AP and lateral radiography of the distal tibia, as well as CT scans (axial, coronal, and sagittal images with reconstruction). All subtypes of the Leonetti classification were included. The evaluators presented different levels of training: two Foot and Ankle fellows and two residents in their last year of training. To determine the interobserver agreement, each case was classified into types I, II, III and IV according to Leonetti. To determine the intraobserver agreement, the cases were analyzed by the same evaluator after 6 weeks. The kappa coefficient (k) was used to determine the degree of agreement between the evaluators, that value was expressed with a 95% confidence interval.
Results: The intraobserver agreement between the first and second evaluation for fellows was moderate and very good. For the residents, it was good and very good. The interobserver agreement for the classification of tibial pilon fractures presented an overall kappa of 0.7156 (95%CI: 0.60 to 0.83), which is a good value when all fractures are considered by all evaluators.
Conclusion: This tibial pilon fracture classification system surpasses previous studies of other classifications in terms of agreement. These agreements were reached with physicians with varying levels of expertise. Our findings contribute to the external and independent validation of this new classification system.
