Abstract
Aim: This study was a prospective validation of the Ottawa Ankle Rules (OAR) in our patient population with ankle injury.
Materials and Methods: This was a prospective study conducted. Each patient’s demographic characteristics, radiography results, and status of meeting OAR criteria were recorded on a previously prepared study form. The descriptive statistics were presented as Mean, Standard Deviation, and percentage. Categorical variables were analyzed using Chi-Square test. The correlation between OAR positivity and presence of a fracture was analyzed using the Spearman’s correlation analysis.
Results: The sensitivity of OAR was 100%, specificity 27%, negative predictive value 100%, and the positive predictive value 17%.
Conclusion: A careful physical examination and use of OAR may allow avoiding unnecessary tests.
