Overview

Ainhum is the autoamputation of a finger or toe as a result of a fibrotic band that constricts the finger or toe until it falls off. Ainhum most often affects the fifth toe on both feet. Ainhum is believed to be triggered by some sort of trauma, but the exact reason why it happens is not well understood. The condition mainly affects people that live in tropical regions.[1]
