McBurney's point is an unreliable landmark for the appendix base. Most appendices are located above or below this traditional anatomical reference, impacting surgical planning.

Area of Science:

  • Anatomy
  • Surgical Education

Background:

  • McBurney's point is a traditional landmark for the base of the appendix.
  • Its clinical description may not accurately reflect anatomical position.

Purpose of the Study:

  • To evaluate the anatomical accuracy of McBurney's point as an appendix landmark.
  • To inform surgical trainees about appendix anatomical variations.

Main Methods:

  • Prospective study of 100 barium enemas.
  • Films centered on McBurney's point with skin marker.
  • Analysis of appendix base location relative to McBurney's point.

Main Results:

  • Only 1% of appendix bases were at McBurney's point.
  • 67% were cephalic (above) and 32% were caudal (below) McBurney's point.

  • Demonstrates significant variability from the traditional landmark.

    • Conclusions:

    • McBurney's point has limitations as a precise anatomical landmark for the appendix.
    • Surgical incision planning should consider appendix anatomical variations.
    • Emphasizes the need for updated anatomical teaching for surgical trainees.
