Kehr's sign

Kehr's sign

Kehr's sign is the occurrence of acute pain in the tip of the shoulder due to the presence of blood or other irritants in the peritoneal cavity when a person is lying down and the legs are elevated. Kehr's sign in the left shoulder is considered a classical symptom of a ruptured spleen. May result from diaphragmatic or peridiaphragmatic lesions, renal calculi, splenic injury or ectopic pregnancy.

Kehr's sign is a classical example of referred pain: irritation of the diaphragm is signalled by the phrenic nerve as pain in the area above the collarbone.

The discovery of this is often attributed to a German gall bladder surgeon named Hans Kehr, but extensive studies into research he conducted during his life shows inconclusive evidence as to whether or not he actually discovered it.
