10.3.1.Acute traumatic injury
Acute traumatic injuries usually involve a single blow from a single application of force — like getting a cross-body block in football. Acute traumatic injuries include the following:

• a fracture - a crack, break, or shattering of a bone
• a bruise - known medically as a contusion - caused by a direct blow, which may cause swelling and bleeding in muscles and other body tissues
• a strain - a stretch or tear of a muscle or tendon, the tough and narrow end of a muscle that connects it to a bone
• a sprain - a stretch or tear of a ligament, the tissue that supports and strengthens joints by connecting bones and cartilage
• an abrasion - a scrape
• a laceration - a cut in the skin that is usually deep enough to require stitches
