Obturator sign

The patient lies on her/his back with the hip and knee both flexed at ninety degrees.

In the clinical context, it is performed when acute appendicitis is suspected.

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.

The obturator sign indicates the presence of an inflamed pelvic appendix.

Evidence shows that the obturator test does not adequately diagnose appendicitis, but can be used in conjunction with other signs and symptoms to make a diagnosis.
