What is a sprain?

A sprain refers specifically to overstretching, pulling, or tearing of a ligament, which are the tough bands of tissue that connect bones to one another at a joint. When a ligament is sprained, it can lead to pain, swelling, and impaired function of the affected joint. Understanding this definition is crucial, especially in a clinical setting, as it helps in diagnosing and managing injuries effectively.

In contrast, a tear in muscle tissue is classified as a strain, not a sprain, which further emphasizes the importance of distinguishing between these two types of injuries. A fracture refers to a break in the bone, and a dislocation involves the bones of a joint being displaced from their normal position. Therefore, recognizing that a sprain specifically impacts the ligaments clarifies the nature of the injury and guides treatment strategies.
