<P> Deep tenderness at McBurney 's point , known as McBurney 's sign , is a sign of acute appendicitis . The clinical sign of referred pain in the epigastrium when pressure is applied is also known as Aaron 's sign . Specific localization of tenderness to McBurney 's point indicates that inflammation is no longer limited to the lumen of the bowel ( which localizes pain poorly ) , and is irritating the lining of the peritoneum at the place where the peritoneum comes into contact with the appendix . Tenderness at McBurney 's point suggests the evolution of acute appendicitis to a later stage , and thus , the increased likelihood of rupture . Other abdominal processes can also sometimes cause tenderness at McBurney 's point . Thus , this sign is highly useful but neither necessary nor sufficient to make a diagnosis of acute appendicitis . Also , the anatomical position of the appendix is highly variable ( for example in retrocaecal appendix , an appendix behind the caecum ) , which also limits the use of this sign as many cases of appendicitis do not cause point tenderness at McBurney 's point . For most open appendectomies ( as opposed to laparoscopic appendectomies ) , the incision is made at McBurney 's point . </P>
