Isolated injury refers to an injury that affects only one specific area or part of the body, rather than multiple areas at once. This type of injury is often easier to diagnose and treat compared to more complex, systemic injuries that involve multiple areas of the body. Isolated injuries can result from various causes such as accidents, overuse, repetitive motion, or sudden trauma. Common examples of isolated injuries include sprains, strains, fractures, and dislocations. Treatment typically involves rest, physical therapy, and sometimes surgery depending on the severity of the injury.
