W20-W49: Exposure to inanimate mechanical forces
W21: Striking against or struck by sports equipment
The group of conditions classified under "Striking against or struck by sports equipment" refer to injuries caused by encounters with sports equipment. These incidents can occur during a wide array of sporting activities and are usually accidental. Symptoms can vary greatly, depending on the nature and force of the impact, and the area of the body affected. For example, being struck by a hard baseball can induce significant bruising, fractures, or concussions, particularly if the head is impacted. On the other hand, striking against softer equipment, such as a misplaced yoga ball, may result in minor bruising or sprains. These conditions do not progress or transmit, as they are incidents with immediate consequences, but repeated injuries in sports may have long-term effects on the body's musculoskeletal or neurological systems.
