[Does Kehr's sign derive from Hans Kehr? A critical commentary on its documentation?].

Kehr's sign (pain in the left shoulder) is a well-known sign for a rupture of the spleen. After a thorough investigation into the body of research conducted by Hans Kehr, one must come to the conclusion that there is insufficient evidence that the term refers to his own work. The question of why the violent pain in the left shoulder during rupture of the spleen is named after the German gall bladder surgeon will remain a mystery of medical history.
