Background

Wandering spleen is most commonly diagnosed in young children as well as women between the ages of 20 and 40. Even so, the disease is very rare and fewer than 500 occurrences of the disease have been reported as of 2005, of which around 148 (including both children and adult cases) were documented to have been from between 1960 and 1992. Less than 0.5% of all splenectomies, surgical removal of the spleen, are performed due to having this disorder.

Characteristics of the disorder include the loss, weakening, or malformation of the ligament
Ligament
In anatomy, the term ligament is used to denote any of three types of structures. Most commonly, it refers to fibrous tissue that connects bones to other bones and is also known as articular ligament, articular larua, fibrous ligament, or true ligament.Ligament can also refer to:* Peritoneal...
