Objective:
To evaluate the intra-observer reproducibility of Schatzker classification for tibial plateau fractures through smartphone applications.
Methods:
Radiographs were evaluated in two incidences (anteroposterior and profile) and CT slices (axial, sagittal and coronal) of 37 patients with tibial plateau fracture. Two evaluators, knee surgery experts, classified the cases by viewing the images of the isolated radiographs and then X-rays associated with CT slices in four different stages via smartphones and then presential assessment. Data were statistically analyzed with the Kappa coefficient (k).
Results:
There was intra-observer agreement by comparing the two methods of evaluation: display or via smartphone, and the analysis made showed statistical significance.
Conclusion:
The use of smartphones did not affect the reliability of Schatzker classification. Level of Evidence III, Diagnostic Study - Investigating a Diagnostic Test.
