ANKLE AND MIDFOOT FRACTURES;

DIAGNOSTIC ACCURACY OF OTTAWA RULES

Abstract

Objectives: To determine the diagnostic accuracy of Ottawa rule in ankle and
midfoot fracture keeping x-ray as gold standard. Study Design: Descriptive study. Setting:
Department of Orthopedics, Lady Reading Hospital Peshawar. Period: June 2014 to May 2016.
Materials and Methods: Through a Cross Sectional Study Design, a total of 175 patients
presenting with suspicion of ankle/mid foot fracture were selected in a consecutive manner
from the OPD and subjected to detection of fracture through Ottawa Ankle Rule followed by
X-ray to confirm the diagnosis of fracture. Results: The mean age group of patients in our
study was 36.1+10.4 years. There were 85.7% males and 14.3% were females. The sensitivity
analysis shows OAR has a sensitivity of 81.2% and specificity 61.9%., positive predictive value
of the OAR is 79.1% and negative predictive value is 65.0% keeping X-ray as a gold standard.
Conclusion: The overall sensitivity and specificity of the OAR lies within an acceptable range
in our local population however, we still recommend further research work over it before
recommendations as a routine screening test for the fracture of ankle or mid foot.
