Which of the following is NOT an acute injury type mentioned?

A skeletal fracture is considered an acute injury type, meaning it occurs suddenly due to trauma or impact, rather than developing over time. Acute injuries are characterized by their immediate onset and are often associated with a specific incident, such as a fall or collision.

Muscle strains, rotator cuff tears, and ACL injuries also fall under acute injuries as they can result from sudden movements, overexertion during physical activity, or accidents. Recognizing the nature of these injuries is crucial for understanding their treatment and recovery processes. Each type of injury may have similar immediate effects, but skeletal fractures distinctly represent a break in bone structure, which is consistent with the acute injury definition.
