Fractures of the neck of the talus: evaluation of reproducibility of Hawkins' classification.

Objective: To evaluate the intraobserver and interobserver reproducibility of Hawkins' classification for fractures of the neck of the talus.
Methods: 20 random cases of fracture of the talus were selected, to be defined according to the classification of types by eight orthopedic surgeons, 13 orthopedic residents and 15 radiology residents.
Results: Using the statistical test of Landis and Koch, measurements of 0.627 and 0.668 were obtained in the first and second evaluations, respectively. These values define a satisfactory agreement for Hawkins' classification.
Conclusion: We conclude that this classification is reproducible between observers, with better values for the more experienced observers. Level of Evidence I, Study Diagnostic - Investigating a diagnostic test.
