Point of special abdominal tenderness indicating acute appendicitis. It lies over and corresponds with the normal position of the appendix.
The point of special tenderness in acute appendicitis; corresponds with the normal position of the base of the appendix.
A point which indicates the usual position of the appendix on the right side of the abdomen, between the hip bone and the navel, which is extremely painful if pressed when the person has appendicitis [Described 1899. After Charles McBurney (1845-1913), US surgeon.]
The location of the most pronounced pain during an acute appendicitis episode is typically found about a third of the distance on an imaginary line connecting the navel to the front part of the hipbone, known as the anterior superior iliac spine. However, this is only true when the appendix is in its standard position. If the appendix is tucked under the colon, the most tender spot might be on the side of the abdomen.
