Rovsing sign is commonly used to describe pain elicited in the right iliac fossa on deep palpation of the left iliac fossa.
It is used in clinical examination to detect peritoneal irritation in the right iliac fossa, most frequently associated with acute appendicitis. Most teaching erroneously describes the sign as elicited by deep palpation or percussion in the left iliac fossa 3. However the sign as described by Rovsing described sliding the hand cranially from the left iliac fossa to push descending colon contents back towards the caecum, distending it and causing right lower quadrant pain 1,3.
A meta-analysis of the usefulness of history, examination findings, blood tests and POCUS in paediatric acute appendicitis presenting to an emergency department found that Rovsing sign was the physical sign correlating best with acute appendicitis (likelihood ratio (LR) 3.52, CI 2.65-4.68). Although this is for the "erroneous" sign (see above) 2.
