Obturator test is performed when the physical suspects the patient may be presenting with acute appendicitis. In this condition, the appendix becomes inflamed and enlarged. The appendix may come into physical contact with the obturator internus muscle, which will be stretched when this maneuver is performed on the right leg. This causes pain and is an evidence in support of an inflamed appendix. Other physical examinations include the Psoas sign and Rovsing’s sign. Please watch the following Obturator sign video.
