W20-W49: Exposure to inanimate mechanical forces

W20: Struck by thrown, projected or falling object(s)

The classification "Struck by thrown, projected or falling object(s)" refers to a group of injuries most often seen in accidents or traumatic events where an individual is hit by an object that has been thrown, projected, or has fallen. These injuries can affect any part of the body and may range from minor bumps and bruises to more serious injury like fractures, concussions, or internal damage depending on the force and nature of the incident. Common symptoms may include pain at the site of impact, bleeding, bruising, swelling, and potentially loss of function if the trauma is severe. The progression of these injuries largely depends on their severity and their timely and appropriate management. For instance, a minor bruise may heal within a few days, while a fracture or internal injury would require professional medical intervention and longer recovery time.
