Area of Science:

  • Emergency Medicine
  • Radiology
  • Orthopedics

Background:

  • Over 95% of patients with ankle injuries undergo radiographic examinations.
  • 85% of these radiographic examinations reveal no fractures, indicating overuse.
  • Need for a diagnostic tool to identify clinically significant fractures.

Purpose of the Study:

  • To develop clinical decision rules for identifying malleolar and midfoot fractures.
  • To reduce unnecessary radiographic examinations in patients with ankle and foot injuries.

Main Methods:

  • Development of the Ottawa Ankle Rules by emergency physicians.
  • Application of these rules to patients presenting with ankle and foot injuries.

Main Results:

  • The Ottawa Ankle Rules effectively identify patients requiring radiographic examination.
  • Implementation of the rules reduced ankle radiographic examinations by 28%.
  • Implementation of the rules reduced foot radiographic examinations by 14%.

Conclusions:

  • The Ottawa Ankle Rules are effective in reducing unnecessary radiographic examinations.
  • These rules aid in the selective use of imaging for ankle and foot injuries.
  • Clinical decision rules improve diagnostic efficiency in emergency settings.
