In the figure,Mc Burney’s point is depicted by:
- It is the name given to the point over the right side of the abdomen that is one-third of the distance from the anterior superior iliac spine to the umbilicus (navel).
- This point roughly corresponds to the most common location of the base of the appendix where it is attached to the cecum.
- Deep tenderness at McBurney’s point, known as McBurney’s sign, is a sign of acute appendicitis.
- For most open appendectomies (as opposed to laparoscopic appendectomies), the incision is made at McBurney’s point.
- Pitfall: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.
