Anthropometric measurements were performed on 51 normal, supine, barium enema examinations to determine the position of the lower pole of the caecum and the base of the appendix relative to palpable bony landmarks (the anterior superior iliac spine and the symphysis pubis). Four quadrants were defined (iliac, umbilical, inguinal and pelvic) by the intersection of the right lateral line and the interspinous line (the line joining the left and right anterior superior iliac spines). The position of the lower pole of the caecum was iliac in 12%, inguinal in 37%, and pelvic in 51%. The appendix or appendix stump was visualised on 53% of the barium examinations. The position of the appendix was iliac in 15%, umbilical in 15%, inguinal in 11%, and pelvic in 59%. The positions of the lower pole of the caecum and base of the appendix are lower and more medial than previously described. 70% of appendices were found to lie inferior to the interspinous line, contrary to established surgical teaching, which assumes McBurney's point to be the surface landmark for the appendix.
对51例正常仰卧位进行钡剂灌肠检查，测量人体测量学指标，以确定盲肠下极和阑尾根部相对于可触及骨性标志（髂前上棘和耻骨联合）的位置。通过右侧侧线和棘间线（连接左右髂前上棘的线）的交点定义了四个象限（髂部、脐部、腹股沟部和盆腔部）。盲肠下极位于髂部的占12%，腹股沟部的占37%，盆腔部的占51%。在53%的钡剂检查中可见阑尾或阑尾残端。阑尾位于髂部的占15%，脐部的占15%，腹股沟部的占11%，盆腔部的占59%。盲肠下极和阑尾根部的位置比先前描述的更低且更靠内侧。发现70%的阑尾位于棘间线下方，这与既定的外科教学观点相反，后者认为麦氏点是阑尾的体表标志。
