What type of injury occurs when a joint is twisted or stretched beyond its normal range of motion?

A sprain occurs when the ligaments that connect bones at a joint are twisted or stretched beyond their normal range of motion. This can happen during activities that involve sudden changes in direction or impact, leading to damage or tearing of the ligaments. Sprains typically result in pain, swelling, and limited joint function.

In contrast, a strain involves injury to muscles or tendons rather than ligaments, resulting from overstretching or overexertion. A fracture refers to a break in a bone, which is a different type of injury altogether. A dislocation occurs when a bone is forced out of its normal position in a joint, which may also involve sprains but is a specific condition distinct from a sprain. Understanding these distinctions helps clarify the nature of the injury and facilitates proper treatment and recovery strategies.
