Diseases and Conditions
A ruptured spleen is a medical emergency that occurs when your spleen develops a break in its surface. Your spleen, located just under your rib cage on your left side, helps your body fight infection and filter old blood cells from your bloodstream.
A ruptured spleen is generally caused by a forceful blow to your abdomen — during a sporting mishap, a fistfight or a car crash, for example. Without emergency treatment, a ruptured spleen can cause life-threatening internal bleeding.
Some people with ruptured spleens need emergency surgery. Others can be treated with several days of hospital care.
