The love of (or sexual attraction to) amputees. It is a fetish focused on amputations, generally of limbs.
There are two subtypes of this fetish. Acrotomophilia is an intense desire for one's partner to be an amputee. Acrotomophiles are also known as "devotees." Apotemnophilia is an intense desire to be an amputee. Aptemnophiles are also known as "wannabes."
That guy on Uuntold Stories of the E.R who chopped of his own hand has Acrotomophilia.
Attraction to amputees, a paraphilia.
