Medical Eponyms
Murphy Sign (1896)
In 1896, Naunyn, in his treatise on cholelithiasis described clinical examination for gallstones with palpation in the right upper quadrant on inspiration and comparing right and left hypochondria.
Naunyn’s method of palpation was published 7 years before that of John B. Murphy (1857 – 1916) and bears the closest resemblance to the clinical examination skill employed today.
If the liver is swollen as the result of the attack (i.e., recently) the organ is always more or less tender, and often very acutely so; but frequently it is tender without being swollen. In such cases it is found that pain is induced when, during a deep inspiration, pressure is made with the hand as far upwards as possible beneath the right costal border. At the moment when the liver impinges upon the tips of the fingers the patient experiences a deep-seated pain which sometimes radiates over the entire hepatic region and on to the epigastrium. By no means rarely, however, the tenderness of the liver is only manifested by tension of the muscles of the anterior abdominal wall on the right side, and in such cases the difference in tension of the right and left side respectively is best observed in the rectus abdominis.
