- Extension of hip will cause pain
Rovsing's sign: Rovsing sign, pressure over the point on the left side corresponding to the McBurney point will elicit the typical pain at the McBurney point on the right side in appendicitis.
- Deep palpation of the left iliac fossa causes pain in the right iliac fossa.
Obturator sign: If an inflamed appendix is in contact with the obturator internus, spasm of the muscle can be demonstrated by flexing and internally rotating the hip. This manoeuvre will cause pain in the hypogastrium.
