avulsion
In medical contexts, this term describes a violent separation of tissue, such as a tendon or a digit, from its origin. It is distinct from a simple cut or laceration because it implies a tearing force that rips the structure away entirely or partially from its attachment point.
In geomorphology, the term refers to a rapid change in the course of a river. This occurs when a stream breaches its banks and creates a new channel, abandoning the old one. This is a sudden, catastrophic event rather than the gradual migration seen in meandering rivers.
