There are basically two types of injuries: acute injuries and overuse injuries.
Acute injuries are usually the result of a single, traumatic event. Common examples include wrist fractures, ankle sprains, shoulder dislocations, and hamstring muscle strain. While overuse injuries are more common in sports than acute injuries, they are subtle and usually occur over time, making them challenging to diagnose and treat. They are the result of repetitive micro-trauma to the tendons, bones, and joints.
Common examples include tennis elbow, swimmer’s shoulder, youth pitching elbow, runner’s knee, jumper’s knee, Achilles tendinitis, and shin splints.
