What is it called when a ligament is overstretched or torn?

When a ligament is overstretched or torn, it is referred to as a sprain. Ligaments are the tough, fibrous tissues that connect bones to each other at joints, and when they are subjected to excessive force—such as twisting or impact—they can become injured. A sprain can vary in severity, ranging from mild stretching of the ligament fibers to complete tears.

This term specifically relates to injuries involving ligaments, distinguishing it from other types of injuries. For instance, a fracture pertains to a break in a bone, while a strain involves injury to a muscle or tendon rather than a ligament. An avulsion refers to a situation in which a fragment of bone is pulled away by a tendon or ligament, which is different from the stretching or tearing of the ligament itself. Thus, the terminology is critical in accurately describing the nature of the injury and the affected anatomical structures.
