What type of injury is characterized by overstretching of ligaments?

A sprain is specifically defined as an injury that results from the overstretching or tearing of ligaments, which are the fibrous tissues that connect bones to each other at a joint. Ligaments provide stability to joints and help them function properly. When a ligament is overstretched, it can lead to pain, swelling, and reduced mobility in the affected area.

In contrast, a fracture involves a break in a bone, a dislocation occurs when the bones in a joint are forced apart, and a strain relates to the overstretching or tearing of muscles or tendons rather than ligaments. Understanding the distinction between these injuries can aid in correct diagnosis and treatment, highlighting the importance of identifying a sprain accurately in the context of first aid and injury management.
