Kehr's sign

The sweep - mark ( Kehr 's sign ) is a radiating to the left shoulder pain symptoms with accompanying hypersensitivity ( hyperesthesia ) of the skin, which is a classic sign of a spleen or tubal rupture, but also in other disorders, often with direct or indirect involvement of the diaphragm (rupture of the diaphragmatic artery ( phrenic ), gastric perforation, subphrenic (sitting below the diaphragm ) abscess ) may occur. In a supine patient with suspected splenic rupture the sweeping character can be triggered by deep better positioning of the head. The sweeping character is an example of referred pain, which is based on an erroneous assignment of a viscerosensory sensation to an area of ​​skin ( dermatome ).

Whether the first description - as long suspected - indeed on Berliner surgeon Hans Kehr (1862-1916) goes back, is unclear.
