McBurney's Sign is primarily used to diagnose which condition?

McBurney's Sign is primarily associated with appendicitis, which is an inflammation of the appendix. This clinical sign is elicited by applying pressure to McBurney's point, located in the right lower quadrant of the abdomen, approximately one-third of the distance from the hip bone to the navel. When a patient has appendicitis, the area tends to be tender, and the patient often experiences increased pain upon release of pressure, known as rebound tenderness.

The use of McBurney's Sign in diagnosing appendicitis is well-rooted in clinical practice, as it helps healthcare providers assess the likelihood of appendicitis based on physical examination findings. Other conditions listed, such as cholecystitis, bowel obstruction, and gastritis, do not typically present with a positive McBurney's Sign, making this sign a specific indicator for appendicitis.
