What is the definition of a stress fracture?

A stress fracture is a tiny crack in a bone that occurs due to repetitive stress or overuse. Unlike acute fractures caused by a sudden impact or trauma, stress fractures develop gradually over time when the muscles and soft tissues can no longer sufficiently absorb shock during physical activities. They are frequently observed in individuals participating in high-impact sports, military training, ballet dancing, running long distances, or engaging in similar physically demanding endeavors.
